    The Female Athlete Triad is a syndrome of the interrelated components of disordered eating, amenorrhea, and osteoporosis. Sometimes inadvertently, but more often by willful dietary restriction, many female athletes do not ingest sufficient calories to adequately fuel their physical or sport activities, which can disrupt menstrual functioning, thereby increasing their risk of bone loss. Although its prevalence is unknown, the Female Athlete Triad is believed to affect many athletes at all ages and all sport competition levels. Even though the Triad affects athletes in all sports, girls and women in sports that emphasize a thin or small body size or shape appear to be most at risk. This article focuses on the risks of the Female Athlete Triad for middle- and high-school-age female athletes as well as the unique issues related to the identification, management, and treatment of the various components of the Triad in this special adolescent subpopulation.

    The female athlete triad is defined as the combination of disordered eating, amenorrhea and osteoporosis. This disorder often goes unrecognized. The consequences of lost bone mineral density can be devastating for the female athlete. Premature osteoporotic fractures can occur, and lost bone mineral density may never be regained. Early recognition of the female athlete triad can be accomplished by the family physician through risk factor assessment and screening questions. Instituting an appropriate diet and moderating the frequency of exercise may result in the natural return of menses. Hormone replacement therapy should be considered early to prevent the loss of bone density. A collaborative effort among coaches, athletic trainers, parents, athletes and physicians is optimal for the recognition and prevention of the triad. Increased education of parents, coaches and athletes in the health risks of the female athlete triad can prevent a potentially life-threatening illness.

    The female athlete triad is a spectrum of interrelated pathophysiologic consequences of low energy availability, menstrual dysfunction, and low bone mineral density. Components of the triad are not only counterproductive to athletic performance goals, but can lead to serious long-term negative health outcomes. Practitioners caring for female athletes play an important role detecting at-risk athletes early in their course along the disease spectrum. Importantly, women who are evaluated for one component of the triad should always be screened for the other two. Detecting the disorder early is the most important factor for preventing the potentially severe consequences, and requires heightened vigilance on the part of all those who work with this special patient population. In this article, we discuss the epidemiology, pathophysiology, diagnosis, evaluation, and management of the female athlete triad.

    The passage of Title IX legislation in 1972 provided enormous opportunities for women to reap the benefits of sports participation. For most female athletes, sports participation is a positive experience, providing improved physical fitness, enhanced self-esteem, and better physical and mental health. Nonetheless, for a few female athletes, the desire for athletic success combined with the pressure to achieve a prescribed body weight may lead to the development of a triad of medical disorders including disordered eating, menstrual dysfunction, and low bone mineral density (BMD)--known collectively as the female athlete triad. Alone or in combination, the disorders of the triad can have a negative impact on health and impair athletic performance.

    The Female Athlete Triad poses serious health risks, both short and long term, to the overall well-being of affected individuals. Sustained low energy availability can impair health, causing many medical complications within the skeletal, endocrine, cardiovascular, reproductive, and central nervous systems. With the surge of females participating in athletics within the past 10 to 15 years, it is both conceivable and likely that the prevalence of this syndrome will continue to grow. Therefore, it is imperative that appropriate screening and diagnostic measures are enacted by a multidisciplinary team of health care providers, counselors, teachers, and dieticians in order to provide the proper care to affected athletes. Initial awareness should take place within the educational confines of elementary and high schools. Screening for female athletes exhibiting risk factors for the triad should also take place at the time of sports physicals. If one component of the triad is identified, the clinician should take the time to effectively workup the other 2. Treatment for each component of the triad includes both pharmacological and nonpharmacological measures, with emphasis placed upon increased energy availability and overall improved nutritional health. Using this all-encompassing type of approach, sports medicine practitioners should feel empowered to continue to promote the lifelong well-being of female athletes in the years to come.

    Context: The female athlete triad (the triad) is an interrelationship of menstrual dysfunction, low energy availability (with or without an eating disorder), and decreased bone mineral density; it is relatively common among young women participating in sports. Diagnosis and treatment of this potentially serious condition is complicated and often requires an interdisciplinary team. Evidence Acquisition: Articles from 1981 to present found on PubMed were selected for review of major components of the female athlete triad as well as strategies for diagnosis and treatment of the conditions. Results: The main goal in treatment of young female athletes with the triad is a natural return of menses as well as enhancement of bone mineral density. While no specific drug intervention has been shown to consistently improve bone mineral density in this patient population, maximizing energy availability and optimizing vitamin D and calcium intake are recommended. Conclusions: Treatment requires a multidisciplinary approach involving health care professionals as well as coaches and family members. Prevention of this condition is important to minimize complications of the female athlete triad. PMID:23016101

    Since the passage of Title IX in 1972, women's participation in physical activity and sports has increased significantly. A concurrent expansion in the body of knowledge regarding women and sports has occurred. Questions regarding menstrual dysfunction and exercise continue, while new questions about menstrual dysfunction and its effect on bone mineral density have arisen. Physical and physiological differences between men and women not only guide treatment, but help fuel policy decisions regarding competition between males and females. It is essential for the physical therapist to remain current on issues related to women and sports in order to better advise and treat the female athlete.

    Participation of adolescents and young women in strenuous sports activity may lead to various metabolic and psychological derangements of clinical relevance to the endocrinologist. The most common manifestations encountered in practice are primary and secondary amenorrhea, reduced bone mineral density and eating disorders. The occurrence of all three together has been named "the athletic triad". The underlying hormonal drivers that lead to some of these manifestations are the reduced leptin level as well as the persistent low grade stress response commonly observed in such females. "Exercise-related female reproductive dysfunction" (ERFRD), can possibly include short-term (infertility) and long-term (osteoporosis) consequences. Functional hypothalamic amenorrhea, a manifestation of ERFRD in adolescence, is an integrated response to the combination of excessive physical and emotional stress, exercise, and/or reduced food intake characterized by decreased endogenous GNRH secretion. The primary aim of treating these athletes should be the prevention of the development of any component of the triad as well as the whole complex by educating athletes, trainers, parents and health care professionals about proper nutrition and safe training. The long term prognosis is good. However, significant long term morbidity may affect these young women later in life.

    The number of girls participating in sports has increased significantly since the introduction of Title XI in 1972. As a result, more girls have been able to experience the social, educational, and health-related benefits of sports participation. However, there are risks associated with sports participation, including the female athlete triad. The triad was originally recognized as the interrelationship of amenorrhea, osteoporosis, and disordered eating, but our understanding has evolved to recognize that each of the components of the triad exists on a spectrum from optimal health to disease. The triad occurs when energy intake does not adequately compensate for exercise-related energy expenditure, leading to adverse effects on reproductive, bone, and cardiovascular health. Athletes can present with a single component or any combination of the components. The triad can have a more significant effect on the health of adolescent athletes than on adults because adolescence is a critical time for bone mass accumulation. This report outlines the current state of knowledge on the epidemiology, diagnosis, and treatment of the triad conditions.

    The practitioner, as well as specialist such as gynecologist and endocrinologist, may face in their office women with eating disorders, abnormalities of menstrual cycles and low bone mass, which may be the first hints of the female athlete triad. In these situations, the practitioner may search other findings of these triad by looking at some particular physical findings and by using appropriate questionnaire. In some advanced forms of this triad specific abnormalities of eating disorders (anorexia and boulimia) may be present as well as amenorrhea and osteoporosis, which may disturb the well-being and cause health damages of women practising sport either as amateur or in a elite setting. An appropriate handling of such disorders has to be proposed to these women.

    The last three decades have witnessed a tremendous increase in female sports participation at all levels. However, increased sports participation of female athletes has also increased the incidence of sport-related injuries, which can be either acute trauma or overuse injuries. Overuse injuries may be defined as an imbalance caused by overly intensive training and inadequate recovery, which subsequently leads to a breakdown in tissue reparative mechanisms. This article will review the most frequent overuse injuries in female athletes in the context of anatomical, physiological, and psychological differences between genders.

    Inadequate dietary intake is the primary nutritional concern of today's female athlete. As these athletes fail to consume enough energy to support the physical demands of training, they become at risk for disordered eating, amenorrhea, and osteoporosis, conditions collectively identified as the female athlete triad. This review addresses nutritional concerns of the female athlete, identification of those at risk, relationship of energy intake to menstrual irregularities, and recently identified chronic diseases associated with the female athlete triad. Strategies are offered to prevent harmful behaviors leading to the comorbidities associated with inadequate dietary intakes.

    After the passage of Title IX in 1972, female sports participation skyrocketed. In 1992, the female athlete triad was first defined; diagnosis required the presence of an eating disorder, amenorrhea, and osteoporosis. However, many athletes remained undiagnosed because they did not meet all three of these criteria. In 2007, the definition was modified to a spectrum disorder involving low energy availability (with or without disordered eating), menstrual dysfunction, and low bone mineral density. With the new definition, all three components need not be present for a diagnosis of female athlete triad. Studies using the 1992 definition of the disorder demonstrated a prevalence of 1% to 4% in athletes. However, in certain sports, many female athletes may meet at least one of these criteria. The actual prevalence of athletes who fall under the "umbrella" diagnosis of the female athlete triad remains unknown.

    Peak bone mass (PBM) is a negative predictor of osteoporosis and lifelong fracture risk. Because osteoporosis is such a prevalent disease with life-threatening consequences, it is important to try to maximize PBM. Adolescence is a critical period for bone acquisition. This article discusses some of the differences in male and female skeletal development and modifiable factors that enhance bone accrual in this age group, particularly in athletes. Hormonal influences, effects of physical activity, and nutritional contributions are included, with a focus on the adolescent athlete. Emphasis is placed on the importance of appropriate energy availability in this age group. We also review prevention and treatment strategies for the female athlete triad (ie, the inter-relationship of decreased energy availability, menstrual irregularity, and low bone density) in adolescents and athletic women. Recommendations for maximizing bone density in both male and female adolescents are discussed.

    Female sports participation at the high school level has significantly increased since the 1970s. Physical activity in females has numerous positive benefits, including improved body image and overall health. Unfortunately, a select population of exercising females may experience symptoms related to the "female athlete triad," which refers to the interrelationships among energy availability, menstrual function, and bone mineral density. Clinically, these conditions can manifest as disordered eating behaviors, menstrual irregularity, and stress fractures. Athletes with conditions related to the triad are distributed along a spectrum between optimal health and disease and may not experience all conditions simultaneously. Previous research related to the triad has primarily focused on collegiate and elite athletes. However, mounting evidence demonstrates that the triad is present in the high school population. High school athletes should be assessed for triad components at preparticipation physicals. In addition, parents, coaches, and health care professionals should be educated and informed about the female athlete triad syndrome. In the presence of triad symptoms, further evaluation and treatment by a multidisciplinary team is strongly recommended for the athlete.

    Participation in sports offers many health benefits to athletes of both sexes. However, subsets of both female and male athletes are at increased risk of impaired bone health and bone stress injuries. The Female Athlete Triad (Triad) is defined as the interrelationship of low energy availability (with or without disordered eating), menstrual dysfunction, and low bone mineral density. The Triad may result in health consequences, including bone stress injuries. Our review presents evidence that an analogous process may occur in male athletes. Our review of the available literature indicates that a subset of male athletes may experience adverse health issues that parallel those associated with the Triad, including low energy availability (with or without disordered eating), hypogonadotropic hypogonadism, and low bone mineral density. Consequently, male athletes may be predisposed to developing bone stress injuries, and these injuries can be the first presenting feature of associated Triad conditions. We discuss the evidence for impaired nutrition, hormonal dysfunction, and low bone mineral density in a subset of male athletes, and how these health issues may parallel those of the Triad. With further research into the mechanisms and outcomes of these health concerns in active and athletic men, evidence-based guidelines can be developed that result in best practice.

    This study examined the prevalence of and relationship between the disorders of the female athlete triad in collegiate athletes participating in aesthetic, endurance, or team/anaerobic sports. Participants were 425 female collegiate athletes from 7 universities across the United States. Disordered eating, menstrual dysfunction, and musculoskeletal injuries were assessed by a health/medical, dieting and menstrual history questionnaire, the Eating Attitudes Test (EAT-26), and the Eating Disorder Inventory Body Dissatisfaction Subscale (EDI-BD). The percentage of athletes reporting a clinical diagnosis of anorexia and bulimia nervosa was 3.3% and 2.3%, respectively; mean ( SD) EAT and EDI-BD scores were 10.6 9.6 and 9.8 7.6, respectively. The percentage of athletes with scores indicating "at-risk" behavior for an eating disorder were 15.2% using the EAT-26 and 32.4% using the EDI-BD. A similar percentage of athletes in aesthetic, endurance, and team/anaerobic sports reported a clinical diagnosis of anorexia or bulimia. However, athletes in aesthetic sports scored higher on the EAT-26 (13.5 10.9) than athletes in endurance (10.0 9.3) or team/anaerobic sports (9.9 9.0, p <.02); and more athletes in aesthetic versus endurance or team/anaerobic sports scored above the EAT-26 cut-off score of 20 (p <.01). Menstrual irregularity was reported by 31% of the athletes not using oral contraceptives, and there were no group differences in the prevalence of self-reported menstrual irregularity. Muscle and bone injuries sustained during the collegiate career were reported by 65.9% and 34.3% of athletes, respectively, and more athletes in aesthetic versus endurance and team/anaerobic sports reported muscle (p =.005) and/or bone injuries (p <.001). Athletes "at risk" for eating disorders more frequently reported menstrual irregularity (p =.004) and sustained more bone injuries (p =.003) during their collegiate career.

    Stress fractures are a common occurrence in athletes, and the incidence of stress fractures in female Division 1 collegiate athletes is double that of men. Hormonal influences on bone and bone morphology may influence the risk for fracture. A high level of suspicion and special imaging procedures allow for accurate diagnosis of these fractures. In stress fractures that are associated with the female athlete triad, addressing the three aspects of the triad--eating disorders, amenorrhea, and osteoporosis--are critical for successful treatment. Preparticipation screening for the presence of signs of the female athlete triad by monitoring weight, energy level, menstrual cycles, and bone mineral density may help to prevent the occurrence of stress fractures in this population.

    Iron deficiency (ID) is the most prevalent micronutrient deficiency disorder in the world. In the developed world, the greatest prevalence of ID and iron deficiency anemia (IDA) occurs in premenopausal women. Premenopausal women experience ID and IDA due to inadequate consumption of dietary iron coupled with iron losses through physiologic processes such as menstruation. Further, female athletes may experience an elevated risk of ID and IDA, as hepcidin, a peptide hormone that inhibits iron absorption and sequesters iron in the macrophage, may rise in response to physical activity. Declines in physical and cognitive performance have been demonstrated in female athletes with ID and IDA. Performance decrements are attenuated as iron status improves. This review will focus on iron status in female athletes, and will include a review of nutritional countermeasures to prevent ID and IDA.

    The aim of this study was to determine the prevalence of the female athlete triad, which is a clinical condition defined as the simultaneous occurrence of disordered eating, amenorrhea, and osteopenia and/or osteoporosis in female athletes. A total number of 224 female athletes from Edirne city participated in our study. Eating attitudes test (EAT 40) and a self-administered questionnaire were used to assess disordered eating behavior and menstrual status respectively. The participants having both disordered eating and amenorrhea were performed dual energy x-ray absorptiometry to evaluate bone mineral density. Thirty seven subjects (16.8%) had disordered eating behavior and 22 subjects (9.8%) were reported to have amenorrhea. Six athletes (2.7%) met two criteria (disordered eating and amenorrhea) of the triad. Of these, only three athletes met all components of the triad. We have found that the prevalence rate of female athlete triad was 1.36% among young Turkish female athletes. Female athletes have under considerable risk for the disordered eating and amenorrhea components of the triad. Key PointsThe prevalence rate of the occurrence of whole criteria of the female athlete triad was 1.36 % in young Turkish athletes in Edirne.Female athletes who met whole criteria of female athlete triad are more prone to the eating disorders.The occurrence of disordered eating behavior was higher in female athletes according to general population.Amenorrhea prevalence was significantly higher in female athletes who had disordered eating.

    Eating disorders are serious mental diseases that frequently appear in female athletes. They are abnormal eating behaviors that can be diagnosed only by strict criteria. Disordered eating, although also characterized as abnormal eating behavior, does not include all the criteria for diagnosing eating disorders and is therefore a way to recognize the problem in its early stages. It is important to identify factors to avoid clinical progression in this high-risk population. Therefore, the purpose of this review is to discuss critical information for the prevention of eating disorders in female athletes. This review discusses the major correlates for the development of an eating disorder. We also discuss which athletes are possibly at highest risk for eating disorders, including those from lean sports and female adolescent athletes. There is an urgent need for the demystification of myths surrounding body weight and performance in sports. This review includes studies that tested different prevention programs’ effectiveness, and the majority showed positive results. Educational programs are the best method for primary prevention of eating disorders. For secondary prevention, early identification is essential and should be performed by preparticipation exams, the recognition of dietary markers, and the use of validated self-report questionnaires or clinical interviews. In addition, more randomized clinical trials are needed with athletes from multiple sports in order for the most reliable recommendations to be made and for some sporting regulations to be changed.

    Context: Physical activity may affect the concentrations of circulating endogenous hormones in female athletes. Understanding the relationship between athletic and physical activity and circulating female hormone concentrations is critical. Objective: To test the hypotheses that (1) the estradiol-progesterone profile of high school adolescent girls participating in training, conditioning, and competition would differ from that of physically inactive, age-matched adolescent girls throughout a 3-month period; and (2) athletic training and conditioning would alter body composition (muscle, bone), leading to an increasingly greater lean–body-mass to fat–body-mass ratio with accompanying hormonal changes. Design: Cohort study. Settings: Laboratory and participants' homes. Patients or Other Participants: A total of 106 adolescent girls, ages 14–18 years, who had experienced at least 3 menstrual cycles in their lifetime. Main Outcome Measure(s): Participants were prospectively monitored throughout a 13-week period, with weekly physical activity assessments and 15 urine samples for estrogen, luteinizing hormone, creatinine, and progesterone concentrations. Each girl underwent body-composition measurements before and after the study period. Results: Seventy-four of the 98 girls (76%) who completed the study classified themselves as athletes. Body mass index, body mass, and fat measures remained stable, and 17 teenagers had no complete menstrual cycle during the observation period. Mean concentrations of log(estrogen/creatinine) were slightly greater in nonathletes who had cycles of <24 or >35 days. Mean log(progesterone/creatinine) concentrations in nonathletes were less in the first half and greater in the second half of the cycle, but the differences were not statistically significant. Conclusions: A moderate level of athletic or physical activity did not influence urine concentrations of estrogen, progesterone, or luteinizing hormones. However, none of the

    Screening female athletes for eating disorders is not performed commonly even though the American College of Sports Medicine, National Athletic Trainer Association, and International Olympic Committee have guidelines recommending screening. Eating disorders are more prevalent in the female athlete population than in the general population and carry short-term and long-term consequences that can affect sport performance. There are several screening tools available that have been studied in the general population and fewer tools that were validated specifically in female athletes. Female athletes with eating disorder pathology often have different factors and environmental pressures contributing to their pathology that can be identified best with an athlete-specific screening tool. We will discuss various screening tools available and the evidence for each one. Screening for eating disorders in all female athletes is an important part of the preparticipation examination and should be done using a tool specifically validated for the female athlete.

    2013-06-01

    Updated prevalence estimates of all 3 components of the Female Athlete Triad, a syndrome characterized by low energy availability, functional hypothalamic amenorrhea, and osteoporosis, is low (0 %-16 %), however, estimates of 1 or 2 concurrent components approach 50 %-60 % among certain athlete groups. Recent research identifies components of the Triad among female adolescent athletes, particularly those participating in leanness sports, such as endurance running. This is alarming, as adolescents require adequate nutrition and normal hormone function to optimize bone mineral gains during this critical developmental period. Current literature highlights new assessments, such as measurements of bone microarchitecture and hormone levels to better evaluate bone strength and the hormonal and metabolic profile of athletes with and at risk for the Triad. Recent data also provides support for additional potential consequences of the Triad, such as endothelial dysfunction and related cardiovascular effects, stress fractures, and musculoskeletal injuries. Additional prospective research is needed to evaluate long-term indicators and consequences of the Triad and identify effective behavioral treatment strategies.

    Objective: To discuss the rehabilitation program after anterior cruciate ligament (ACL) reconstruction in the female athlete. In addition, we will discuss 8 unique characteristics identified in the female athlete and specific training drills to address and correct the potentially deleterious effects of these unique characteristics. Background: The female athlete appears to be more susceptible to noncontact ACL injuries than the male athlete. There seem to be many differences between the female and male athlete that may contribute to the increased injury rate in the female athlete. These variations include anatomical and neuromuscular considerations and differences. Description: Based on the unique characteristics of the female athlete and the anatomical and neuromuscular dissimilarities, a specially designed rehabilitation program has been established for the female athlete after ACL surgery. Clinical Advantages: The rehabilitation drills discussed in this article challenge the neuromuscular system through proprioception, kinesthesia, dynamic joint stability, neuromuscular control, and perturbation training activities. Improving the female athlete's neuromuscular system will, we believe, expedite the injured athlete's recovery after ACL injury or surgery. Although the concepts discussed are part of a postoperative rehabilitation program after ACL surgery, these concepts may also be implemented as a preventive program to assist in reducing the incidence of ACL injuries in the female athlete.

    Context: Very few women have leadership positions in athletic training (ie, head athletic training positions) in intercollegiate athletics. Research exists on the barriers to attaining the role; however, our understanding about the experiences of those currently engaged in the role is limited. Objective: To examine the experiences of female head athletic trainers as they worked toward and attained the position of head athletic trainer. Design: Qualitative study. Setting: National Collegiate Athletic Association Division I setting. Patients or Other Participants: Eight female athletic trainers serving in the role of head athletic trainer participated in our study. The mean age of the participants was 45 ± 12 years, with 5 ± 1.5 years of experience in the role of head athletic trainer and 21 ± 10 years of experience as athletic trainers. Data Collection and Analysis: We conducted phone interviews with the 8 participants following a semistructured format. Interviews were transcribed verbatim and analyzed following a general inductive approach as described by Thomas. To establish credibility, we used a peer reviewer, member checks, and multiple-analyst triangulation. Results: Six major themes emerged from our analysis regarding the experiences of female head athletic trainers. Opportunities to become a head athletic trainer, leadership qualities, and unique personal characteristics were discussed as factors leading to the assumption of the role of the head athletic trainer. Where women hold back, family challenges, and organizational barriers speak to the potential obstacles to assuming the role of head athletic trainer. Conclusions: Female head athletic trainers did not seek the role, but through persistence and encouragement, they find themselves assuming the role. Leadership skills were discussed as important for success in the role of head athletic trainer. Life balancing and parenting were identified as barriers to women seeking the role of head athletic

  8. A systematic review of studies comparing body image concerns among female college athletes and non-athletes, 1997-2012.

    PubMed

    Varnes, Julia R; Stellefson, Michael L; Janelle, Christopher M; Dorman, Steven M; Dodd, Virginia; Miller, M David

    2013-09-01

    Research prior to 2001 indicated that athletes experienced better body image than non-athletes, with no differences among sport types. Since then, female athletes have become increasingly sexually objectified in the media, and the sociocultural beauty ideal has shifted to emphasize appearing both athletic and thin. Part I of this paper explores the literature describing these changes. Part II presents a systematic and comprehensive literature review of 10 recent studies comparing body image concerns (BIC) among collegiate female athletes and non-athletes to identify the current status of BIC in female athletes. Findings indicate that involvement in collegiate athletics provides some protection from BIC; however, this protection appears attenuated for athletes in more feminine sports (e.g., gymnastics), and higher level athletes (Division I). Researchers should examine how sociocultural pressures unrelated to competition predict female athletes' BIC using measures that focus on objectification, positive body image, body functionality, and thin- and athletic-ideal internalization.

  9. Pathophysiology of bone loss in the female athlete.

    PubMed

    Lambrinoudaki, Irene; Papadimitriou, Dimitra

    2010-09-01

    Low bone mass is frequent among female athletes. The "female athlete triad" is a term that describes the interaction among energy availability, menstrual function, and bone metabolism that may lead to amenorrhea and osteopenia or osteoporosis. The main pathophysiologic mechanisms that lead to low bone mass in female athletes are low energy availability and functional hypothalamic amenorrhea. Increased energy expenditure and/or decreased energy intake, as well as the presence of eating disorders, are associated with low bone mass. In addition, menstrual dysfunction is quite common, especially among athletes competing in sports favoring leanness, and also associates with low bone mass. Screening for bone loss in female athletes should take place in the presence of amenorrhea or body mass index <18 kg/m(2) . Management of low bone mass aims to restore normal energy availability and nutritional habits. Hormone replacement therapy has no effect in abnormally underweight patients unless normal eating behaviors are restored.

    Summary Background There is a greater incidence of menstrual disorders in female athletes than in their sedentary counterparts. The menstrual disorder is reported in female athletes suffering from athletic triad syndrome, while few data in those free of this syndrome are available. The study aims to ascertain the presence of menstrual disorders and the eventual relationship with myocardial performance in female athletes practicing different sports. Methods A sample of 64 subjects aged 18.5±2 was selected and divided into 3 groups (37 subjects practicing rhythmic gymnastics, 11 swimmers, and 16 volleyball players). All underwent echocardiography, biompendance analysis, and answered a questionnaire. Results All anthropometrics parameters were normal. Few athletes reported menstrual disorders. No association between the presence of menstrual disorders and BMI. All echo results were within the normal range. Cardiac Mass Index (CMI) was normal for all athletes despite in swimmers significantly higher values (90.64±14.9 g/m2) compared to the volleyball players (78.25±14.0 g/m2; p<.04) and rhythmic gymnasts (77.89±13.4 g/m2; p<.009) were found. Conclusions Despite menstrual disorders are represented among female athletes, the eventual relationship with the sport practiced is not so evident. Questionnaire should be used to identify menstrual disorders in non-elite athletically active females. PMID:27900290

    PubMed

    Gropper, Sareen S; Blessing, Daniel; Dunham, Kim; Barksdale, Jeffrey M

    2006-01-01

    Iron status was assessed in 70 female athletes aged 18-25 yr participating in collegiate cross-country track, tennis, softball, swimming, soccer, basketball, and gymnastics. No significant differences in mean hemoglobin, hematocrit, serum iron, total iron-binding capacity, transferrin saturation, and ferritin were found among teams. The mean concentrations of each parameter for each of the teams were within the normal ranges. However, several athletes from different sports had suboptimal iron status indexes. Of 17 athletes with a serum ferritin concentration < or = 15 microg/L, 8 (4 freshmen, 2 sophomores, 2 unknown) also exhibited low serum iron concentrations (< 60 microg/dL) and low transferrin saturation (< 16%). Thirteen (6 freshmen, 3 sophomores, 2 juniors, 2 seniors) of 51 (25%) athletes failed to consume two-thirds of the Recommended Dietary Allowance for iron and exhibited suboptimal serum concentrations of ferritin, iron, and/or transferrin saturation. Of nine athletes taking iron supplements, one exhibited suboptimal iron status. In summary, nonanemic iron depletion was present among female collegiate athletes involved in many different sports and in all years of participation (freshmen, sophomore, junior, and senior athletes). Female athletes should continue to be individually and routinely evaluated for nutritional deficiencies throughout their collegiate athletic careers.

    2010-06-01

    The adolescent female athlete has become a common part of the sports environment at all levels from childhood play to professional adult sports. This article considers various issues common to this athlete to help clinicians care for their patients. Basic sports physiology is reviewed and then specific conditions are considered, including iron deficiency anemia, stress urinary incontinence, breast issues (ie, pain, asymmetry, galactorrhea, injury), the female athlete triad (ie, menstrual dysfunction, abnormal eating patterns, and osteopenia or osteoporosis), and injuries. Clinical conundrums are considered including the difficulty in caring for a dedicated athlete whose intense love of her sport may lead to menstrual and bone loss complications. The knowledgeable clinician in the twenty-first century can be of considerable help to the female athlete who is at and beyond puberty.

    2017-04-01

    Maximal inspiratory mouth pressure (MIP) is a common measurement of inspiratory muscle strength, which is often used in a variety of exercises to evaluate the effects of inspiratory muscle training. The characteristics of MIP in elite female athletes remain unclear. This study aimed to determine the characteristics of MIP at rest in a variety of sport-specific elite female athletes. We also aimed to clarify if there is a sex difference of MIP in elite athletes. We studied 169 Japanese elite female athletes and 301 Japanese elite male athletes. MIP was assessed using a portable autospirometer with a handheld mouth pressure meter. Female athletes who regularly experienced exercise-induced inspiratory muscle fatigue tended to have higher MIP values. The mean absolute MIP value in females was significantly lower than that in males. However, when this value was expressed relative to body mass, this difference disappeared. Our findings provide essential information for prescribed, sport-specific, inspiratory muscle training in elite female athletes.

  19. Long term consequences of the female athlete triad.

    PubMed

    2013-06-01

    In the past 40 years, female sports participation, particularly at the high school level, has significantly increased. Physical activity in females has numerous positive benefits, including improved body image and overall health. Unfortunately, a select population of exercising females may experience symptoms related to the female athlete triad, which refers to the interrelatedness of energy availability, menstrual function, and bone mineral density. Clinically, these conditions can manifest as disordered eating behaviors, menstrual irregularity, and stress fractures. Triad symptoms are distributed along a spectrum between optimal health and disease; all of the components of the triad may not be affected simultaneously. The female athlete triad was first identified in 1992. Since that time, a vast amount of research related to the identification, management and prevention of this condition has been published. More recently, research related to the long term effects of triad components has come into light. Women who were diagnosed with female athlete triad syndrome as adolescents and young adults in the 1990s are now in their 30s and 40s; negative long term effects of the female athlete triad, such as low bone mineral density, are now starting to manifest. Women of all ages should be assessed for triad components during routine annual physical examinations; appropriate measures to treat any current triad components should be implemented. In addition, women in their 30s, 40s and early 50s should be screened for a history of the female athlete triad. Multidisciplinary management of these conditions is strongly recommended.

    Information is limited on the effect of exercise on bone density in young eumenorrheic athletes. We studied 12 Caucasian intercollegiate volleyball players (V), nine basketball players (B), ten swimmers (S), and 13 non-athletes (N) with bone density measurements by photon absorptiometry of their calcaneus and lumbar spine (L2-L4). The effect of athletic status on bone density was analyzed by multivariate analysis of covariance, with height and weight as covariates. The bone densities reported below are mean +/- SE, adjusted for the covariates; units = g.cm-2, P less than 0.005. The swimmers had a significantly lower mean density in the lumbar spine than all other groups; the non-athletes' mean density was also lower than that of volleyball players (V = 1.31 +/- 0.03, B = 1.26 +/- 0.04, N = 1.18 +/- 0.03, S = 1.05 +/- 0.03). The volleyball and basketball players' mean calcaneal densities were greater than those of the swimmers and non-athletes (V = 0.530 +/- 0.017, B = 0.564 +/- 0.023, N = 0.438 +/- 0.018, S = 0.375 +/- 0.019). The higher bone densities for athletes in vertical weight-bearing activities are consistent with some but not all published data. The swimmers' low bone density in the lumbar spine, less than published values for amenorrheic runners, was unexpected.

  1. Use of the preparticipation physical exam in screening for the female athlete triad among high school athletes.

    PubMed

    De La Torre, Dena M; Snell, B J

    2005-12-01

    The female athlete triad comprises 3 individual but interrelated conditions associated with athletic training: disordered eating, amenorrhea, and osteoporosis. Each condition is of medical concern, but when found within the triad, they can have serious medical consequences. The purpose of this study was to evaluate the effectiveness of preparticipation history and physical forms in high school athletic programs to screen for the triad, and to determine the prevalence of educational programs related to the female athlete triad. Results suggest that a majority of high school athletic programs are not adequately screening girls for the components of the triad, and schools lack educational programs targeting athletes and coaches. School nurses have the potential to play a vital role in the prevention and early identification of the triad through a preparticipation physical exam that specifically screens female athletes and in the implementation of educational programs for athletes and coaches regarding the disorders of the female athlete triad.

    The female athlete triad is an increasingly prevalent condition involving disordered eating, amenorrhea, and osteoporosis. An athlete can suffer from all 3 components of the triad, or just 1 or 2 of the individual conditions. The main element underlying all the aspects of the triad is an adaptation to a negative caloric balance. Screening for these disorders should be an important component of an athlete's care. Prevention and treatment should involve a team approach, including a physician, a nutritionist, and a mental health provider.

    Women participating in a wide range of competitive sports are at higher risk of developing eating disorders, menstrual irregularities and osteoporosis, which are generally referred to as the 'female athlete triad'. The objective of this study was to determine the prevalence of female athlete triad and factors associated with this condition among athletes participating in different sports. A total of 67 elite female athletes aged between 13-30 years participated in the study and were subdivided into the 'leanness' and 'non-leanness' groups. Eating disorders were assessed using a body image figure rating and the Eating Disorder Inventory (EDI) with body dissatisfaction (BD), drive for thinness (DT), bulimia (B) and perfectionism (P) subscales. Menstrual irregularity was assessed with a self-reported menstrual history questionnaire. Bone quality was measured using a quantitative ultrasound device at one-third distal radius. Prevalence of the female athlete triad was low (1.9%), but the prevalence for individual triad component was high, especially in the leanness group. The prevalence of subjects who were at risk of menstrual irregularity, poor bone quality and eating disorders were 47.6%, 13.3% and 89.2%, respectively, in the leanness group; and 14.3%, 8.3% and 89.2%, respectively, in the non-leanness group. Since the components of the triad are interrelated, identification of athletes at risk of having any one component of the triad, especially those participating in sports that emphasise a lean physique, is an important aid for further diagnosis.

    The number of female athletes participating at the high school, collegiate, and elite levels has increased nearly 10-fold since the passage of Title IX. President Nixon signed title IX into law in 1972. It required that all schools receiving federal funding provide equal opportunities for men and women. With this large increase in high-level female athletes comes a special set of medical and orthopaedic issues. One of the most important is the female athlete triad. The triad consists of disordered eating, amenorrhea, and premature osteoporosis. Currently, this problem is largely unrecognized. The purpose of this article is to help to educate orthopaedic nurses about this important issue so that we can detect the triad early and help address this growing national health issue.

    2010-12-01

    The prevalence of anxiety disorders in adolescents range from 6% to 20%, and it is much higher for anxiety symptoms not meeting criteria for a specific anxiety disorder. The prevalence is much higher in females. Athletes participating in sports experience different levels of stress from competitive sports. For most young athletes (generally 13 to 24 years old, i.e., high-school and college age group) sport participation is reported to be no more stressful than many other activities of daily student or work life in general where competition is involved and performance is measured. Some level of sport related performance anxiety is considered to be normal and healthy; however, extreme anxiety in athletes can be detrimental in these performance situations. A number of factors may contribute to the development, severity, and persistence of performance anxiety related to sport participation. This article reviews the definitions, theories, clinical presentation, evaluation, and management principles of performance anxiety symptoms in young athletes.

    The female athlete triad is a medical condition often observed in physically active girls and women and involves three components: (1) low energy availability with or without disordered eating, (2) menstrual dysfunction, and (3) low bone mineral density. Female athletes often present with one or more of the three triad components, and early intervention is essential to prevent its progression to serious end points that include clinical eating disorders, amenorrhea, and osteoporosis. This consensus statement presents a set of recommendations developed following the first (San Francisco, CA) and second (Indianapolis, IN) International Symposia on the Female Athlete Triad. This consensus statement was intended to provide clinical guidelines for physicians, athletic trainers, and other health care providers for the screening, diagnosis, and treatment of the female athlete triad and to provide clear recommendations for return to play. The expert panel has proposed a risk stratification point system that takes into account magnitude of risk to assist the physician in decision making regarding sport participation, clearance, and return to play. Guidelines are offered for clearance categories, management by a multidisciplinary team, and implementation of treatment contracts.

    2015-01-01

    The purpose of this study was to assess the risk of disordered eating (DE) among female athletes in lean and non-lean sports using the ATHLETE survey. The ATHLETE survey is divided into six different constructs, and a high score indicates a high risk for DE. Eighty-three varsity female athletes from eight Campbell University sports teams completed the survey and a medical history form anonymously. The sports were divided into sports that traditionally have a high risk for DE (lean sports) and those with a low risk (non-lean sports). The lean sports included: cheerleading, cross country/track and field, swimming, and volleyball. The non-lean sports included: basketball, golf, soccer, and softball. The total mean score of the ATHLETE survey for the lean sports was 100.1 ± 17.4, compared to the non-lean sports scoring 90.1 ± 16.9, p = 0.011. The two constructs that showed significant difference between lean and non-lean sports were Social Pressure on Body Shape (lean: 12.2 ± 3.9, non-lean: 9.4 ± 4.6, p = 0.005) and Team Trust (lean: 7.4 ± 3.3, non-lean: 5.6 ± 2.2, p = 0.004). The results indicate that lean sports exhibited a higher risk for development of DE compared to athletes participating in non-lean sports. It appears that the primary influence of DE in these female athletes came from external social pressures that may therefore dictate their exercise and nutritional habits. PMID:27293502

    This paper, which was part of the International Association of Athletics Federations (IAAF) 2007 Nutritional Consensus Conference, briefly reviews the components of the female athlete triad (Triad): energy availability, menstrual status, and bone health. Each component of the Triad spans a continuum from health to disease, and female athletes can have symptoms related to each component of the Triad to different degrees. Low energy availability is the primary factor that impairs menstrual dysfunction and bone health in the Triad. We discuss nutritional issues associated with the Triad, focusing on intakes of macronutrients needed for good health, and stress fractures, the most common injury associated with the Triad. Finally, we briefly discuss screening and treatment for the Triad and the occurrence of the Triad in men.

    The power and performance model of sport stresses a sport ethic of doing "whatever it takes" to win (Coakley, 2004). Uncritical acceptance of this model may lead to various health-compromising behaviors. Employing achievement goal theory, we examine why female athletes may adopt the power and performance approach. An ego motivational climate and a…

    We examined heavy training-induced changes in baroreflex sensitivity, plasma volume and resting heart rate and blood pressure variability in female endurance athletes. Nine athletes (experimental training group, ETG) increased intense training (70-90% VO2max) volume by 130% and low-intensity training (< 70% Vo2max) volume by 100% during 6-9 weeks, whereas the corresponding increases in six control athletes (CG) were 5% and 10% respectively. Maximal oxygen uptake (VO2max) in the ETG and CG did not change, but in five ETG athletes VO2max decreased from 53.0 +/- 2.2 (mean +/- SEM) (CI 46.8-59.2) ml kg-1 min-1 to 50.2 +/- 2.3 (43.8-56.6) ml kg-1 min-1 (P < 0.01), indicating overtraining. Baroreflex sensitivity (BRS) measured using the phenylephrine technique and blood pressure variability (BPV) did not change, but the low-frequency power of the R-R interval variability increased in the ETG (P < 0.05). The relative change in plasma volume was 7% in the ETG and 3% in the CG. The changes in BRS did not correlate with the changes in plasma volume, heart rate variability and BPV. We conclude that heavy endurance training and overtraining did not change baroreflex sensitivity or BPV but significantly increased the low-frequency power of the R-R interval variability during supine rest in female athletes as a marker of increased cardiac sympathetic modulation.

    Introduction Due to increased life expectancy among the population, studying the vocal parameters of the elderly is key to promoting vocal health in old age. Objective This study aims to analyze the profile of the extension of speech of elderly female choristers, according to age group. Method The study counted on the participation of 25 elderly female choristers from the Choir of Messianic Church of São Paulo, with ages varying between 63 and 82 years, and an average of 71 years (standard deviation of 5.22). The elders were divided into two groups: G1 aged 63 to 71 years and G2 aged 72 to 82. We asked that each participant count from 20 to 30 in weak, medium, strong, and very strong intensities. Their speech was registered by the software Vocalgrama that allows the evaluation of the profile of speech range. We then submitted the parameters of frequency and intensity to descriptive analysis, both in minimum and maximum levels, and range of spoken voice. Results The average of minimum and maximum frequencies were respectively 134.82–349.96 Hz for G1 and 137.28–348.59 Hz for G2; the average for minimum and maximum intensities were respectively 40.28–95.50 dB for G1 and 40.63–94.35 dB for G2; the vocal range used in speech was 215.14 Hz for G1 and 211.30 Hz for G2. Conclusion The minimum and maximum frequencies, maximum intensity, and vocal range presented differences in favor of the younger elder group. PMID:26722341

    The purpose of the study was to compare the prevalence of disordered eating between female college athletes and non-athletes and explore emotion regulation as a potential mediator of the link between participation in athletics and disordered eating symptoms. Data for this cross-sectional study came from 527 college students in a mid-western state of the USA in fall of 2013 (376 non-athletes and 151 athletes). Disordered eating symptoms and emotion regulation were assessed utilizing the Eating Attitudes Test and the Difficulties with Emotion Regulation Scale in a survey-based format. The prevalence of disordered eating was higher in non-athletes (16.5%, vs. 6.6%; X(2)=62.8; p<.05). Non-athletes reported more signs and symptoms of disordered eating than athletes (p<.01). A linear regression approach indicated a statistically significant indirect effect (0.63, CI95=0.18, 1.20) of athletic-status on disordered eating via emotion regulation; however, this effect did not reach practical significance. Our findings show that female athletes in our sample were somewhat protected from disordered eating compared to non-athletes, but the mechanism of this relationship is unclear. A further in-depth examination of other factors, such as self-esteem and body satisfaction, that may have contributed to this finding is warranted utilizing a large sample of female college students and athletes representing a variety of sports.

    The aim of the study was to assess fitness profile of elite Croatian female taekwondo athletes and to determine which physical, physiological and motor characteristics differentiate mostly the successful from the less successful fighters. Thirteen national taekwondo champions were divided into two groups according to their senior international competitive achievements. Physiological characteristics, including maximal oxygen uptake (VO2max), were assessed during a continuous progressive treadmill test. The measured motor abilities included explosive and elastic leg strength, maximal strength, muscular endurance, anaerobic alactic power, agility and flexibility. Differences between the successful and less successful athletes were determined using independent t-test. Even though the differences were not statistically significant, the successful athletes had somewhat less fat (2.3%) and were taller by 5.8 cm. The successful athletes achieved significantly higher maximum running speed (15.8 +/- 0.5 versus 14.9 +/- 0. 7 km h(-1); p < 0.05), their ventilatory anaerobic threshold was significantly higher (41.4 +/- 4.1 versus 37.6 +/- 2.0 ml kg(-1) min(-1); p < 0.05) at a significantly lower heart rate (166.8 +/- 6.8 versus 171.0 +/- 8.2 beats min(-1); p < 0.05) than in the less successful athletes. Significant differences were also found in three tests of explosive power (p < 0.05), anaerobic alactic power (p < 0.01), and lateral agility (p < 0.05). The performance of taekwondo female athletes primarily depends on the anaerobic alactic power, explosive power expressed in the stretch-shortening cycle movements, agility and aerobic power.

    Background: Osteitis pubis represents a non-infectious inflammation of the pubic symphysis causing varying degrees of lower abdominal and pelvic pain. Although, the disease is believed to affect mainly young athletic patients, it is also encountered in other specific patient groups. Both conservative and surgical treatment options are available. While for elite athletes surgical treatment is indicated, leading to fast pain relief and mobilization, for non-athletic patients no clear indication can be established. Methods: Eight non-athletic women with osteitis pubis, referred to our Department for treatment, were evaluated. All were initially treated conservatively with bed rest, per os non steroidal anti-inflammatory drugs and physical therapy. Results: Seven patients improved significantly with conservative treatment while one displayed no improvement and was treated surgically with arthrodesis. Conclusion: We conclude that, for non-athletic female patients suffering from osteitis pubis, surgery is rarely required and that conservative treatment by means of non steroidal anti inflammatory drugs and physical modalities represents a fair option regarding pain and limitation of everyday activity.

    Objective To determine the prevalence of the female athlete triad (low energy availability, menstrual dysfunction and low bone mineral density) in high school varsity athletes in a variety of sports compared with sedentary students/controls. Design Prospective study. Setting Academic medical center in the Midwest. Participants Eighty varsity athletes and eighty sedentary students/controls volunteered for this study. Intervention Subjects completed questionnaires, had their blood drawn and underwent bone mineral density testing. Main Outcome Measures Each participant completed screening questionnaires assessing eating behavior, menstrual status and physical activity. Each subject completed a 3-day food diary. Serum hormonal, TSH and prolactin levels were determined. Bone mineral density (BMD) and body composition were measured by dual energy x-ray absorptiometry (DXA). Results Low energy availability was present in similar numbers of athletes (36%) and sedentary/control subjects (39%; p=0.74). Athletes suffered more menstrual abnormalities (54%) compared with sedentary students/controls (21%) (p=<0.001). DXA revealed that 16% of the athletes and 30% of the sedentary/controls had low BMD (p=0.03). Risk factors for reduced BMD include sedentary control student, low BMI and increased caffeine consumption. Conclusions A substantial number of high school athletes (78%) and a surprising number of sedentary students (65%) suffer from one or more components of the triad. Given the high prevalence of triad characteristics in both groups, education in the formative elementary school years has the potential to prevent several of the components in both groups, therefore, improving health and averting long-term complications.

    Early detection of the female athlete triad is essential for the long-term health of adolescent female athletes. The purpose of this study was to assess relationships between common anthropometric markers (ideal body weight [IBW] via the Hamwi formula, youth-percentile body mass index [BMI], adult BMI categories, and body fat percentage [BF%]) and triad components, (low energy availability [EA], measured by dietary restraint [DR], menstrual dysfunction [MD], low bone mineral density [BMD]). In the sample (n = 320) of adolescent female athletes (age 15.9± 1.2 y), Spearman's rho correlations and multiple logistic regression analyses evaluated associations between anthropometric clinical cutoffs and triad components. All underweight categories for the anthropometric measures predicted greater likelihood of MD and low BMD. Athletes with an IBW >85% were nearly 4 times more likely to report MD (OR = 3.7, 95% CI [1.8, 7.9]) and had low BMD (OR = 4.1, 95% CI [1.2, 14.2]). Those in <5th percentile for their age-specific BMI were 9 times more likely to report MD (OR 9.1, 95% CI [1.8, 46.9]) and had low BMD than those in the 50th to 85th percentile. Athletes with a high BF% were almost 3 times more likely to report DR (OR = 2.8, 95% CI [1.4, 6.1]). Our study indicates that low age-adjusted BMI and low IBW may serve as evidence-based clinical indicators that may be practically evaluated in the field, predicting MD and low BMD in adolescents. These measures should be tested for their ability as tools to minimize the risk for the triad.

    Clinical Scenario: Eating disorders in female athletes are a commonly underdiagnosed condition. Better screening tools for eating disorders in athletic females could help increase diagnosis and help athletes get the treatment they need. Focused Clinical Question: Should screening tools be used to detect eating disorders in female athletes? Summary of Key Findings: The literature was searched for studies that included information regarding the sensitivity and specificity of screening tools for eating disorders in female athletes. The search returned 5 possible articles related to the clinical question; 3 studies met the inclusion criteria (2 cross-sectional studies, 1 cohort study) and were included. All 3 studies reported sensitivity and specificity for the Athletic Milieu Direct Questionnaire version 2, the Brief Eating Disorder in Athletes Questionnaire version 2, and the Physiologic Screening Test to Detect Eating Disorders Among Female Athletes. All 3 studies found that the respective screening tool was able to accurately identify female athletes with eating disorders; however, the screening tools varied in sensitivity and specificity values. Clinical Bottom Line: There is strong evidence to support the use of screening tools to detect eating disorders in female athletes. Screening tools with higher sensitivity and specificity have demonstrated a successful outcome of determining athletes with eating disorders or at risk for developing an eating disorder. Strength of Recommendation: There is grade A evidence available to demonstrate that screening tools accurately detect female athletes at risk for eating disorders.

    2012-02-01

    With the rising participation of women in sports events, the prevalence of eating disorders and the female athlete triad (FTS), a syndrome of disordered eating, amenorrhea, and osteoporosis, have also increased in recent years. FTS is often seen in sports that emphasize thinness (e.g. gymnastics, figure skating and dancing) and also in endurance events. Elements of the FTS are pathophysiologically linked, leading to several disease risks and even to mortality. In spite of the considerable knowledge about sports nutrition, there is no consensus as to the correct nutrition regime for the female athlete. There is consensus that minimizing fluctuations in 'target-body-weight' is an indication of a long-term energy balance. Female athletes (e.g. in endurance events and gymnastics) are less likely to achieve the recommended carbohydrates (CHO) and fat consumption due to chronic or episodic constraints of total energy intake while struggling to achieve or maintain low levels of body fat. It is recommended that dietary CHO and fat content be increased to preserve fat-free mass thus enhancing health and performance. Energy balance should also be maintained during recesses. Furthermore, within-day episodes of energy deficits/surplus (measured by the frequency and/or magnitude of the episodes) should be monitored and treated closest to the time of the incidents.

    The incidence of rotator cuff tear increases with age. Degenerative rotator cuff tears are commonly seen in athletes above 40 years. These athletes are commonly involved in overhead activities. Repetitive microtrauma is a more important factor in rotator cuff degeneration than acute trauma. Conservative treatment is the mainstay treatment for these injuries. A case report of an elderly athlete who sailed competitively is presented. The clinical and radiographic presentations, management and rehabilitation of degenerative rotator cuff tears are discussed.

    To examine the effect of concurrent verbal encouragement on the performance of the WAnT in female athletes vs. female non-athletes. College-age female subjects were recruited where ten of the subjects were intercollegiate athletes (ATH, n1 =10) and the nine were non-athletes (NON, n2 =9). The WAnT was novel to all subjects and the subjects were blinded to the study's purpose. Prior to the experimental trials, subjects were measured for body composition and performed a familiarity WAnT trial without verbal encouragement. Subjects then performed the WAnT twice, once with concurrent verbal encouragement (VE) and once without (NVE), in a balanced cross-over design. Peak (PP) and mean power (MP), and total work (TW) were compared between ATH and NON across VE and NVE using an ANOVA (1 between, 1 within), α=0.05. ATH and NON did not differ (p>0.05) in age or body composition with the exception of fat-free mass which differed significantly (ATH=53.7±6.6, NON=46.1±5.7 kg) (p<0.05). A significant (p<0.05) main effect for ATH/NON was observed where ATH outperformed NON when pooled across VE/NVE trials for PP (ATH=13.0±1.4, NON=11.3±1.7 W·kg(-1)), MP (ATH=7.7±1.1, NON=6.7±0.9 W·kg-1) and TW (ATH=232±35, NON=201±26 J·kg(-1)). When pooled across all subjects (ATH and NON), the VE/NVE trials did not differ (p>0.05) for PP (VE=12.4±1.7, NVE=12.0±1.9 W·kg(-1)), MP (VE=7.3±1.1, NVE=7.2±1.2 W·kg(-1)) and TW (VE=219±33, NVE=215±35 J·kg(-1)). The ATH/NON interaction with VE/NVE was not significant (p>0.05). Concurrent verbal encouragement does not affect performance on the WAnT in females, nor does it affect WAnT performance in female athletes and non-athletes differently.

    With increasing numbers of women competing in high school and collegiate athletics, it is important that physicians become familiar with injury patterns and medical conditions unique to the female athlete. Observations and clinical data have elucidated unique biomechanical, anatomic and hormonal factors that predispose skeletally mature female athletes to anterior cruciate ligament (ACL) injuries, patellofemoral disorders and lower extremity stress fractures. Additionally, younger female athletes are particularly at risk of developing components of the "Female Athlete Triad" (more recently included under the syndrome of "Relative Energy Deficiency in Sport" [RED-S]): disordered eating, amenorrhea and osteoporosis. An understanding of the pathophysiology of these conditions has led to the development of programs that can treat their underlying causes, decrease susceptibility to injury, and improve the long-term health of the female athlete. This paper is intended to provide physicians with a review of the sex-specific etiology, prevention and treatment of injuries common to the female athlete.

    One purpose of the present study was to compare Social Physique Anxiety (SPA) scores among four different female groups (physique-salient (PS) athletes-aerobics competitors and divers, n = 63; weight-restricted athletes-rowers, n = 60; non-physique-salient (NPS) athletes--soccer, n = 75; and non-athlete students, n = 53). A second purpose of the study was to examine relations between SPA and disturbed eating attitudes among these four groups. Participants completed the Social Physique Anxiety Scale (SPAS; Hart, Leary, & Rejeski, 1989) and the Eating Attitude Test (EAT; Garner & Garfinkel, 1979). With respect to purpose one, an analysis of variance (ANOVA) with SPA (i.e., 9-item single factor model of the SPAS) as the dependent measure, failed to reach significance (F (3,184) = 1.61, p> .05). With respect to purpose two, significant relations were found between SPA and EAT scores for all four groups. Inferential comparison of the bivariate correlations (Fisher's Z transformations), however, showed no significant differences between groups. In addition, a moderated regression analysis was computed using EAT scores as the dependent measure. The variables were entered in the following order: SPA, followed by dummy vectors for each sport-type category, and then the interaction term between SPA and the dummy vectors. Results showed that there was no significant interaction effect. Thus, these analyses, taken together. suggest that the type of sport activity does not serve to moderate relations between SPA and disordered eating. Implications of the findings are discussed.

    2000-09-01

    Iron status was studied in 126 female endurance athletes and 52 control subjects, all aged 16-20 years. The study aimed at identifying factors responsible for iron deficiency. Twenty-six percent of athletes and 50% of controls had latent iron-deficiency without anemia symptoms. A too low intake of iron (especially heme iron: 0.3 mg daily), and of nutrients influencing iron metabolism, were identified as main causes of iron deficiency in control subjects. In athletes, whose iron intake was sufficient (14.6 mg), the principal cause of iron deficiency were blood losses due to menstruation. High level of physical activity, expressed as training volume and experience, did not adversely affect iron stores, as these were higher than in control subjects and the incidence of iron deficiency was much lower than in the control group. It was concluded that an increased intake of iron and of dietary factors involved in iron metabolism prevented possible exercise-induced losses of iron in young athletes.

    Marathon runners are ranked in 5-year age groups. However the extent to which 5-year groupings facilitates equitable competition has not been evaluated. The aim of this study was to evaluate the effect of relative age in male and female marathon running. Marathon finishing times for the top ten male (aged 20-69 years) and female athletes (aged 20-64 years) were obtained from the 2013 New York and Chicago marathons. Intra-class and inter-class validity were evaluated by comparing performances within (intra-class) and between (inter-class) the 5-year age groups. Results showed intra-class effects in all male age groups over 50 years, in all female age groups over 40 years, and in male and female 20-24 age groups (p < 0.05). Inter-class differences existed between the 20-24 and 25-29 age groups in both males and females, between all male age groups over 50 years, and between all female age groups over 40 years (p < 0.05). This study provided the first evaluation of the effects of relative age in male and female marathon running. The results provide preliminary but compelling evidence that the relatively older male athletes in age groups over 50 years and the relatively older females in age groups over 40 years are competitively disadvantaged compared to the younger athletes in these age groups. Key points Results showed a curvilinear relationship between age and marathon running performance with the negative effect of age becoming more pronounced in older runners. Relative age effects were found in all age groups over age 50 years in males and over age 40 years in females indicating that the relatively older runners were competitively disadvantaged compared to the relatively younger runners in these age groups. Relative age affected the 20-24 age classification which is consistent with the hypothesis that marathon performance improves until peak performance occurs in the 25-29 age classification.

    This study was conducted to describe and compare various anthropometric, body composition, cardiorespiratory, metabolic and neuromuscular characteristics of 12 female athletes, members of the Puerto Rico national softball team. The subjects were divided into three categories according to their game specific requirements (game position): infielders (n = 5), outfielders (n = 4), and pitchers (n = 3). The mean and standard deviations of all the variables in each group was calculated. These athletes demonstrated high levels of body fat and below optimal levels of flexibility, cardiorespiratory endurance, and muscular strength and endurance. The results revealed deficiencies in the health related fitness components and in the physical preparation for sports competition. These results also suggest that the subjects are at risk for the development of cardiovascular diseases, sport injuries, and poor sport performance.

    2007-12-01

    Sports medicine physicians often encounter athletes with at least one component of the Female Athlete Triad-disordered eating, menstrual dysfunction, and altered bone mineral density. Recognizing these conditions early is critical because prolonged exposure can lead to serious, potentially irreversible, health consequences. Knowledge of the pathophysiology, detection, and treatment of these problems has evolved significantly. This review focuses on the newer scientific findings in this important area of women's health. There remains a distinct lack of prospective epidemiologic data assessing prevalence and causes, and outcome studies on the efficacy of prevention and treatment of the Triad disorders. Nevertheless, the underlying message remains that participation in sports and physical activity benefits the long-term health of girls and women, and should be encouraged.

    Postural control is a crucial element in regular training of athletes, development of complex technical movement, and injury prevention; however, distributing factor of the postural control such as fatigue have been neglected by athletic trainers in novice and inexperienced athletes. The objective of this study was to compare changes in dynamic postural control of young female athletes and non-athletes after a fatigue protocol. Thirty females (15 athletes and 15 non-athletes) with no orthopedic problems were recruited to participate in this study. All participants completed the pre-SEBT (Star Excursion Balance Test) in eight directions at baseline; then they performed a 20- minute fatigue protocol following which post-SEBT was measured. Rating of perceived exertion was measured using the Borg scale immediately before, mid-way through (i.e. after the third station), and after performing the fatigue protocol (i.e. immediately before the post-SEBT). Female non-athlete groups had significant differences in dynamic balance performance after fatigue in the medial, posterormedial, and posterior directions (p < 0.01) measured by SEBT. Athletes, however, showed no significant changes after the fatigue protocol. Our results indicates the importance of evaluation and monitoring of dynamic postural control of the novice with progressing the exercise time. Our findings could also help coaches to develop trainings focused on the three directions of medial, posterormedial, and posterior directions and aimed at exercises increasing fatigue resistance.

    This study sought to investigate how interpersonal communication between coaches and female athletes influences the female athletes' perceptions of body image and health choices. Much of the current literature has focused on the fact that female athletes are at risk for disordered eating and a distorted body image due to susceptibility to the feminine "thin-ideal" while maintaining the fitness levels necessary to compete in their sport. However, very little research has examined how interpersonal interaction plays a role in female athletes' body image perceptions and health behaviors. Utilizing the Communication Theory of Identity (CTI) as a lens to examine communication between female athletes and their coaches, the researchers analyzed transcripts from in-depth interviews with 28 female athletes and identified themes within the personal, relational, enacted, and communal layers of identity. Coach communication with their female athletes was found to be influential to the athletes' body images and health choices.

    Context: Research has suggested that the prevalence of young women with eating disorders (EDs) is increasing, but determining the exact prevalence of EDs within the female student–athlete (FS-A) population is difficult. Looking at certain traits may help us to identify their level of susceptibility to developing an ED. Objective: To determine the susceptibility of FS-As to EDs in relation to self-concept, including self-esteem and body image. Design: Cross-sectional study. Setting: Athletic training and health centers at National Collegiate Athletic Association Division I, II, and III institutions via e-mail questionnaire correspondence. Patients or Other Participants: A total of 439 FS-As from 17 participating institutions completed the questionnaires. The sample was primarily white (83.1%) and underclass (61.8%). Main Outcome Measure(s): The questionnaire consisted of 4 parts: 3 subscales of the Eating Disorder Inventory-2, the Rosenberg Self-Esteem Scale, the Body Cathexis Scale, and demographic items. Results: A total of 6.8% of FS-As were susceptible to anorexia and 1.8% were susceptible to bulimia. The majority of FS-As (61%) reported normal self-esteem levels, whereas 29.4% had high self-esteem. Overall, 64.5% were satisfied and 23% were very satisfied with their body image. Conclusions: These results are generally positive in that they suggest FS-As have high levels of self-concept and are at low risk to develop EDs. However, these findings do not mean that all concerns should be dismissed. Although more than 90% of the respondents were not susceptible to an ED, there are still FS-As who may be. Athletic departments should evaluate their FS-As' levels of self-concept so that their susceptibility to EDs can be addressed. The emotional aspect of health care should be included in providing holistic care for student–athletes. Athletic trainers often are the primary health care providers for FS-As, so they should be made aware of this concern. PMID:24762233

    The purpose of this study was to determine the effect of postactivation potentiation (PAP)-inducing activities in 4 separate studies examining vertical (VJP) and horizontal (HJP) jump performance, shot put performance (SPP), and sprint performance (SP), in National Collegiate Athletic Association Division II athletes. Study 1: 12 male (mean ± SD; age = 20.2 ± 2.0 years; height = 178.1 ± 6.2 cm; weight = 73.3 ± 6.43 kg) and 8 female (age = 20.1 ± 1.0 years; height = 169.6 ± 5.5 cm; weight = 59.8 ± 7.6 kg) track athletes participated in HJP and VJP testing before and after performing a parallel back squat (PBS) at 85% 1 repetition maximum (RM). Study 2: 10 (6 men and 4 women) shot put throwers (age = 20.6 ± 0.7 years; height = 182.1 ± 9.8 cm; weight = 102.8 ± 23.6 kg) participated in SPP testing for control (C), 3RM bench press, and 3RM PBS protocols. Study 3: 7 football players (age = 20.4 ± 1.6 years; weight = 87.8 ± 8.3 kg; height = 184.3 ± 7.2 cm) participated in SP testing before (PBS1) and after (PBS2) performing a 3RM PBS. Study 4: 11 football players (age = 20.3 ± 1.8 years; height = 180.6 ± 7.5 cm; weight = 86.1 ± 12.8 kg) participated in VJP testing for C and 3RM PBS protocols. Results of study 1: There was a significant (p ≤ 0.05) increase in VJP (PRE = 61.9 ± 12.3 cm; POST = 63.6 ± 11.6 cm) and HJP (PRE = 93.7 ± 11.0 cm; POST = 95.9 ± 11.5 cm). Study 2: SPP after PBS (11.67 ± 1.92 m) was not different vs. C (11.77 ± 1.81), but bench press (11.91 ± 1.81 m) was significantly greater (p ≤ 0.05) than both PBS and C. Study 3: SP time was significantly lower for PBS2 (4.6014 ± 0.17995 seconds) vs. PB1 (4.6557 ± 0.19603 seconds). Study 4: There was no difference in VJP for C (68.35 ± 2.16 cm) vs. PBS (68.12 ± 2.51 cm). Our data show that a 3RM PBS resulted in significant improvements in VJP, HJP, SPP, and SP in National Collegiate Athletic Association Division II male and female athletes.

  1. The female athlete triad: an emerging role for physical therapy.

    Over the last thirty years, participation by girls and women in organized athletics has increased dramatically. This presents unique challenges in the area of sports medicine, orthopaedics, and pediatrics. While the benefits of participation in sports and exercise vastly outweigh the risks of permanent injury, an evolving concern is the number of stress fractures in active women. The female athlete triad ("triad") describes the coexistence of 3 distinct medical conditions that may occur in athletic girls and women. Originally, the triad included eating disorders, amenorrhea, and osteoporosis. Presently, it includes eating disorders/disordered eating behavior, amenorrhea/oligomenorrhea, and decreased bone mineral density (osteoporosis and osteopenia). Briefly, when coupled with inadequate nutrition, the high caloric expenditure of exercise training resultsin a sustained negative caloric balance or low energy availability, which is exquisitely sensed by the hypothalamus, initiating a complex neuroendocrine adaptive cascade. This cascade is associated with changes in the hypothalamic-pituitary-ovarian axis, such that estrogen levels are decreased, resulting in reproductive dysfunction that may include amenorrhea, oligomenorrhea, or anovulation. Low estrogen in otherwise young healthy women, like menopause, is associated with decreased bone mineral density and increased risk of fractures. The triad is not an inevitable consequence of participation in sports or physical activity at any level, however, exercise may contribute to the disruption of caloric balance. The triad is a complex disorder that requires intervention by a multidisciplinary team. Physical therapists bring a unique expertise to the team. The present review summarizes each component of the triad, component linkage, and the role of physical therapy in prevention, assessment, and intervention.

  8. Female athletes: a population at risk of vitamin and mineral deficiencies affecting health and performance.

    PubMed

    McClung, James P; Gaffney-Stomberg, Erin; Lee, Jane J

    2014-10-01

    Adequate vitamin and mineral status is essential for optimal human health and performance. Female athletes could be at risk for vitamin and mineral insufficiency due to inadequate dietary intake, menstruation, and inflammatory responses to heavy physical activity. Recent studies have documented poor iron status and associated declines in both cognitive and physical performance in female athletes. Similarly, insufficient vitamin D and calcium status have been observed in female athletes, and may be associated with injuries, such as stress fracture, which may limit a female athlete's ability to participate in regular physical activity. This review will focus on recent studies detailing the prevalence of poor vitamin and mineral status in female athletes, using iron, vitamin D, and calcium as examples. Factors affecting the dietary requirement for these vitamins and minerals during physical training will be reviewed. Lastly, countermeasures for the prevention of inadequate vitamin and mineral status will be described.

  9. Dynamic neuromuscular analysis training for preventing anterior cruciate ligament injury in female athletes.

    PubMed

    Hewett, Timothy E; Myer, Gregory D; Ford, Kevin R; Slauterbeck, James R

    2007-01-01

    Female athletes are four to six times more likely to sustain an anterior cruciate ligament (ACL) injury than male athletes. Since the enactment of Title IX, male athletic participation at the high school level has remained steady (3.8 million), whereas female athletic participation has increased tenfold (from 0.3 to 3.0 million). Geometric growth in athletic participation and the higher injury rate in female athletes have led to gender inequity in ACL injury rates. Most ACL injuries occur as a result of noncontact mechanisms such as during landing from a jump or while making a lateral pivot. Dynamic knee instability, caused by ligament dominance (decreased dynamic neuromuscular control of the joint), quadriceps dominance (decreased hamstring strength and recruitment), and leg dominance (side-to-side differences in strength and coordination) may be responsible for gender inequity in ACL injury rates.

    The female athlete triad (Triad), links low energy availability (EA), with menstrual dysfunction (MD), and impaired bone health. The aims of this study were to examine associations between EA/MD and energy metabolism and the prevalence of Triad-associated conditions in endurance athletes. Forty women [26.2 ± 5.5 years, body mass index (BMI) 20.6 ± 2.0 kg/m(2), body fat 20.0 ± 3.0%], exercising 11.4 ± 4.5 h/week, were recruited from national teams and competitive clubs. Protocol included gynecological examination; assessment of bone health; indirect respiratory calorimetry; diet and exercise measured 7 days to assess EA; eating disorder (ED) examination; blood analysis. Subjects with low/reduced EA (< 45 kcal/kg FFM/day), had lower resting metabolic rate (RMR) compared with those with optimal EA [28.4 ± 2.0 kcal/kg fat-free mass (FFM)/day vs 30.5 ± 2.2 kcal/kg FFM/day, P < 0.01], as did subjects with MD compared with eumenorrheic subjects (28.6 ± 2.4 kcal/kg FFM/day vs 30.2 ± 1.8 kcal/kg FFM/day, P < 0.05). 63% had low/reduced EA, 25% ED, 60% MD, 45% impaired bone health, and 23% had all three Triad conditions. 53% had low RMR, 25% hypercholesterolemia, and 38% hypoglycemia. Conclusively, athletes with low/reduced EA and/or MD had lowered RMR. Triad-associated conditions were common in this group of athletes, despite a normal BMI range. The high prevalence of ED, MD, and impaired bone health emphasizes the importance of prevention, early detection, and treatment of energy deficiency.

    The aims were to examine the percentage of female elite athletes and controls reporting sexual harassment and abuse (SHAB), and whether a higher percentage of female athletes with eating disorders (ED) had experienced SHAB. A questionnaire was administered to the total population of female elite athletes (n = 660) and controls (n = 780) aged 15-39 years. Sexual harassment and abuse were measured through 11 questions, ranging from light to severe SHAB. In addition, questions about dietary-, menstrual- and training-history and the Eating Disorder Inventory were included. The response rate was 88% for athletes and 71% for controls. Athletes (n = 121) and controls (n = 81) classified as "at risk" for ED and non-ED controls participated in a clinical interview. A higher percentage of controls compared with athletes reported experiences of SHAB in general (59% vs. 51%, P < 0.001). A lower percentage of athletes had experienced SHAB inside sports than outside sport (28% vs. 39%, P < 0.001). A higher percentage of ED athletes than non-ED athletes had experienced SHAB (66% vs. 48%, P < 0.01), both inside sport and outside sport. In spite of the fact that a higher percentage of controls compared with athletes had experienced SHAB, it is necessary to formulate clear guidelines, set up educational workshops and implement intervention programs for both ED and SHAB in sport.

    2016-03-01

    Functional hypothalamic amenorrhea is a diagnosis of exclusion that is common in female athletes, particularly those participating in aesthetic sports (ballet, other dance genres, figure skating, and gymnastics) and endurance sports (cross-country running). Although common, it should be considered abnormal even in the high-level elite athlete. Amenorrhea in combination with low energy availability and low bone density is labeled "the Female Athlete Triad." Studies have demonstrated numerous long-term consequences of athletes suffering from all or a portion of this triad, including increased rate of musculoskeletal injuries, stress fractures, abnormal lipid profiles, endothelial dysfunction, potential irreversible bone loss, depression, anxiety, low self- esteem, and increased mortality. This article provides the clinician with the tools to evaluate an athlete with secondary amenorrhea, reviews the recommended treatment options for affected athletes, and discusses when to return to the activity in an effort to facilitate "healthy" participation.

    As female athletic participation has increased, the positive effects of exercise on health have become evident. However, with this growth in sports activity, a set of health problems unique to the female athlete has emerged. The female athlete triad as first described in 1992 by the American College of Sports Medicine consisted of disordered eating, amenorrhea, and osteoporosis; the definition was updated in 2007 to include a spectrum of dysfunction related to energy availability, menstrual function, and bone mineral density. For this review, a comprehensive search of databases-MEDLINE In-Process & Other Non-Indexed Citations, MEDLINE, EMBASE, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, and Scopus, from earliest inclusive dates to January 2013-was conducted by an experienced librarian with input from the authors. Controlled vocabulary supplemented with keywords such as female athlete triad, amenorrhea, oligomenorrhea, fracture, osteopenia, osteoporosis, bone disease, anorexia, bulimia, disordered eating, low energy availability was used to search for articles on female athlete triad. Articles addressing the prevalence, screening, and management of the female athlete triad were selected for inclusion in the review. This article reviews the current definitions of the triad components, epidemiology, pathophysiology, and recommended screening and management guidelines. The lack of efficacy of current screening of athletes is highlighted. Low energy availablity, from either dietary restriction or increased expenditure, plays a pivotal role in development of the triad. Athletes involved in "lean sports" (those that emphasize weight categories or aesthetics, such as ballet, gymnastics, or endurance running) are at highest risk. Treatment is centered on restoring energy availability to reverse adverse changes in the metabolic milieu. Prevention and early recognition of triad disorders are crucial to ensure timely intervention

    The objective of this study was to assess high school coaches' knowledge, attitudes, communication, and management decisions with respect to the Female Athlete Triad and to determine whether results are patterned by coach gender. Data were obtained through an online survey of high school coaches (n = 227). Significant differences were found between male and female coaches in certain attitudes and communication behaviors related to eating and menstrual irregularity. School or district level policies may help reduce these differences and may help mitigate the health consequences for athletes related to possible differential prevention and detection of the comorbidities of the Female Athlete Triad.

    There are relatively few studies on female athletes examining cardiac size and function and how these measures relate to maximal oxygen uptake (VO2max). When determining sports eligibility, it is important to know what physiological adaptations and characteristics may be expected in female athletes, taking body and cardiac size into account. The purposes of this study were (a) to compare right and left heart dimensions and function in female endurance athletes (ATH) and in non-athletic female controls of similar age (CON); and (b) to explore how these measures related to VO2max. Forty-six ATH and 48 CON underwent a maximal bicycle exercise test and an echocardiographic examination at rest, including standard and color tissue Doppler investigation. All heart dimensions indexed for body size were larger in ATH (all P < 0.01). The diastolic mitral E/A ratio was 27% higher in ATH (P < 0.001) while systolic left and right atrio-ventricular longitudinal displacement was 7% (P = 0.002) and 15% (P < 0.001) larger in ATH, respectively. Half (50.3%) of the variability in VO2max could be explained by left ventricular end-diastolic volume. Our results could be useful in evaluating female endurance athletes with suspected cardiac disease and contribute to understanding differences between female athletes and non-athletes.

    2003-09-01

    Iron deficiency is the most prevalent nutritional deficiency in the United States. This condition has been reported to affect 60% of female athletes. The Centers for Disease Control and Prevention emphasize screening for anemia in women of childbearing age. The purpose of this study was to determine the number of National Collegiate Athletic Association (NCAA) Division I-A schools that implement screening for iron deficiency in female athletes as well as the screening policies for those who do. A link to an online survey was sent to 94 NCAA Division I-A schools to determine current practices concerning screening and treating female athletes for iron deficiency. There was a 58% response rate. Frequencies for each response were computed. Forty-three percent of responding institutions report screening female athletes for iron deficiency. This study suggests that screening for iron deficiency in female athletes at NCAA Division I-A schools is not a routine procedure and, for those who do screen, variability exists in the criteria for diagnosis, as well as in treatment protocols. Standard protocols for assessment and treatment of iron deficiency in female athletes need to be developed and implemented.

    Background Anterior cruciate ligament (ACL) rupture is the biggest concern for orthopedic surgeons who are involved in sports injuries, so most of ACL reconstruction surgeries are sports related. ACL injuries in female athletes are 2 - 8 times more common than male athletes in similar sport injuries. Objectives The aim of this study was to compare knee laxity changes in the menstrual cycle in female athletes referred to the orthopedic clinic of Imam Khomeini hospital in the north of Iran, Sari, 2013. Patients and Methods The present descriptive study was conducted on 40 female athletes that were referred to the orthopedic clinic. Hormone levels, such as estrogen and progesterone were assessed by one laboratory in 3 phases of the menstrual cycle. We used Lachman test and anterior drawer test for knee laxity rate. The descriptive statistics were calculated as indices of central distribution of bonds (x ± SD) and relative frequency distribution was used for qualitative variables. Results The results of the current study showed that there is no significant difference in ACL laxity in female athletes in three phases of menstrual cycle; namely menstruation time, ovulation time and mid-luteal phase. Conclusions Despite numerous studies and research in the field of knee laxity and effects of female hormones, many researchers do not agree about the effect of female hormones on knee laxity. The current study also reported no relationship between female hormones and knee laxity, while statistics show fundamental difference between male and female athletes. PMID:28144404

    Although there are numerous benefits to women from athletic participation, a complex combination of endocrine and metabolic factors exaggerates risk for a serious health concern: the female athlete triad. The purpose of this article is to provide updates on new issues related to the triad, specifically the relationship between athletic-associated amenorrhea and endothelial dysfunction-a potential fourth component to the triad that is a concern for future cardiovascular risk, public health issues, and athletic performance. Folic acid should be considered a potential safe and inexpensive therapeutic treatment to restore endothelial-dependent vasodilation.

    Background An estimated 30 to 40 million school children participate in sports in the United States; 34% of middle-school participants become injured and seek medical treatment at an annual cost close to $2 billion. The purpose of the current study was to evaluate the injury incidence and rates in female athletes in the middle-school setting during the course of 3 seasons. Methods Female basketball, soccer, and volleyball players were recruited from a single county public school district in Kentucky consisting of 5 middle schools. A total of 268 female athletes (162 basketball, 26 soccer, and 80 volleyball) participated. Athletes were monitored for sports-related injury and number of athlete exposures (AEs) by an athletic trainer. Injury rates were calculated for specific types of injuries within each sport. Injury rates for games and practices were also calculated and compared for each sport. Results A total of 134 injuries were recorded during the 3 sport seasons. The knee was the most commonly injured body part (99 injuries [73.9%]), of which patellofemoral dysfunction (31.3%), Osgood-Schlatter disease (10.4%), and Sinding-Larsen-Johansson/patella tendinosis (9%) had the greatest incidence. The ankle was the second most commonly injured body part, accounting for 16.4% of all injuries. The overall rates of injury by sport were as follows: soccer, 6.66 per 1000 AEs; volleyball, 3.68 per 1000 AEs; and basketball, 2.86 per 1000 AEs. Conclusions Female middle-school athletes displayed comparable injury patterns to those seen in their high-school counterparts. Future work is warranted to determine the potential for improved outcomes in female middle-school athletes with access to athletic training services. Clinical Relevance As the participation levels and number of injuries continue to rise, middle-school athletes demonstrate an increasing need for medical services provided by a certified athletic trainer.

    ACL tear is a major concern among athletes, coaches and sports scientists. More than taking the athlete away from training and competition, ACL tear is a risk factor for early-onset of knee osteoarthritis, and, therefore addressing strategies to avoid such injury is pertinent not only for competitive athletes, but for all physically active subjects. Imbalances in the prelanding myoelectric activity of the hamstrings and quadriceps muscles have been linked to ACL injuries. We investigated the effect of landing from different heights on prelanding myoelectric activity of the hamstrings and quadriceps muscles in recreational athletes. Thirty recreational athletes (15 male and 15 female) performed three bilateral drop jumps from two different heights; 20cm and 40cm while myoelectric activity of the vastus medialis, rectus femoris, biceps femoris and medial hamstrings were collected. When increasing the height of drop landing tasks prelanding normalized myoelectric activity of the quadriceps was increased by 15-20% but no significant changes were found for the hamstrings. Female athletes exhibited higher activity of the medial hamstrings compared to their male counterparts. We concluded that increasing the height of drop landing tasks is associated with increased myoelectric activity of the quadriceps but not the hamstrings in recreational athletes. These differences in muscle activity may be related to increased risk for ACL injury when the height is increased. Female athletes demonstrated higher recruitment of the medial hamstrings.

    Context: The recent increase in women's varsity soccer participation has been accompanied by a lower extremity injury rate that is 2 to 6 times that of their male counterparts. Objective: To define the differences between lower extremity biomechanics (knee abduction and knee flexion measures) and performance (maximal vertical jump height) between National Collegiate Athletic Association Division I and III female soccer athletes during a drop vertical jump. Design: Mixed 2 × 2 design. Setting: Research laboratory. Patients or Other Participants: Thirty-four female collegiate soccer players (Division I: n = 19; Division III: n = 15) participated in the study. The groups were similar in height and mass. Intervention(s): Each subject performed a maximal vertical jump, followed by 3 drop vertical jumps. Main Outcome Measure(s): Kinematics (knee abduction and flexion angles) and kinetics (knee abduction and flexion moments) were measured with a motion analysis system and 2 force platforms during the drop vertical jumps. Results: Knee abduction angular range of motion and knee abduction external moments were not different between groups (P > .05). However, Division I athletes demonstrated decreased knee flexion range of motion (P = .038) and greater peak external knee flexion moment (P = .009) compared with Division III athletes. Division I athletes demonstrated increased vertical jump height compared with Division III (P = .008). Conclusions: Division I athletes demonstrated different sagittal-plane mechanics than Division III athletes, which may facilitate improved performance. The similarities in anterior cruciate ligament injury risk factors (knee abduction torques and angles) may correlate with the consistent incidence of anterior cruciate ligament injury across divisions.

    In Spring 2003, a qualitative approach was used to investigate relevant beliefs and norms associated with ephedra initiation and perceived addiction to the drug among 43 primarily minority athletes, attending a historically Black university in the southwestern region of the United States, who self-identified as past users. In general, participants stated that their second ephedra use event occurred on the same day as or the day after initiation. The majority of participants perceived that addiction was established by routine and eccentric behavior. Male athletes stated they used ephedra for improved athletic performance while females stated they used the drug for weight loss. Male participants stated it is difficult to quit ephedra use because of the resulting decrease in athletic performance, sickness, and weight gain. Female athletes were more concerned with their appearance. These findings are important in determining the early extent to which addiction is self-identified.

    While the benefits of physical activity are numerous, the female athlete triad poses a significant health risk to young athletes. Emerging research links the triad to endothelial dysfunction--a sentinel event in cardiovascular disease--suggesting that this complex interplay of metabolic and endocrine factors may be described more accurately as a tetrad. Effective treatment of the triad/tetrad requires a multidisciplinary approach. Emphasis must be placed on prevention, recognition, and treatment of triad for the promotion of healthy nutritional and activity profiles in female athletes across their lifespans.

    Sports and exercise settings as well as other socio-cultural environments emphasize a thin and physically fit female body. However, there is a clear need for a better understanding of the physical and psychological correlates of social physique anxiety and body image dissatisfaction in female athletes. This study aimed to examine the association of the social physique anxiety, body image satisfaction, and personality with the anthropometric measurements in female college athletes according to their sport type using the Co-Plot technique. The sample included 63 female athletes ranging in age from 18 to 26. Results of the Co-Plot analysis revealed a significant association among social physique anxiety, personality and anthropometric measurements. This means that certain physical measurements may lead to greater social physique anxiety and body image dissatisfaction in female athletes. It was found that females having higher levels of social physique anxiety and thus, lower levels of body image satisfaction may be less emotionally stable and more negatively perfectionist. In conclusion, the results of the present study provided evidence to the claim that both physical self-perception and anthropometric measurements may be closely associated with psychological criteria in female athletes.

    ABSTRACT Objective: To determine the prevalence of sexually transmitted diseases in female athletes. Methods: An observational, cross-sectional study was conducted including 50 female athletes with mean age of 20±3 years. Colposcopy, pap smear, and polymerase chain reaction for Chlamydia trachomatis, human papillomavirus and Neisseria gonorrhoeae were performed. Blood samples were collected to test for the human immunodeficiency virus, syphilis, hepatitis B and C. The athletes presenting clinical diseases or conditions identifiable by laboratory tests were treated and followed up in the unit. Results: Forty-six percent of the participants were unaware of sexually transmitted diseases. The prevalence of sexually transmitted diseases among athletes was 48% (24 cases). Human papillomavirus was the most frequent agent (44%). Considering the human papillomavirus genotypes, subtype 16 was the most prevalent (53%), followed by 11-6 (22%) and 18 (13%). Two athletes tested positive for C. trachomatis. There were no cases diagnosed of infection by N. gonorrhoeae, syphilis, hepatitis B, hepatitis C and human immunodeficiency virus. However, only 26 athletes had been vaccinated for hepatitis B. Conclusion: The prevalence of sexually transmitted diseases in female athletes was high. Primary prevention measures (hepatitis B and human papillomavirus vaccination) and secondary (serology, pap smears) must be offered to this specific group of women. The matter should be further approached in sports. PMID:24728243

    PURPOSE: Prevention of the female athlete triad is essential to protect female athletes' health. The aim of this study was to investigate the knowledge, attitudes and behaviours of regularly exercising adult females towards eating patterns, menstrual cycles and bone health. METHODS: A total of 191 female exercisers, aged 18-40 y, engaging in ≥2 hr/wk of strenuous activity, completed a survey. After excluding 11 surveys (due to incomplete answers), the 180 participants were categorised into lean-build sports (n=82; running/athletics, triathlon, swimming, cycling, dancing, rowing), non lean-build sports (n=94; basketball, netball, soccer, hockey, volleyball, tennis, trampoline, squash, Australian football) or gym/fitness activities (n=4). RESULTS: Mean (±SD) training volume was 9.0±5.5 hr/wk, with participants competing from local up to international level. Only 10% of respondents could name the 3 components of the female athlete triad. Regardless of the reported history of stress fracture, 45% of the respondents did not think that amenorrhoea (absence of menses for ≥ three months) could affect bone health, and 22% of those involved in lean-build sports would do nothing if experiencing amenorrhoea (vs. 3.2% in non lean-build sports, p=0.005). Lean-build sports, history of amenorrhoea and history of stress fracture were all significantly associated with not taking action in the presence of amenorrhoea (all p<0.005). CONCLUSIONS: Few active Australian women are aware of the detrimental effects of menstrual dysfunction on bone health. Education programs are needed to prevent the female athlete triad and ensure appropriate actions are taken by athletes when experiencing amenorrhoea.

    There is little research investigating relationships between the Functional Movement Screen (FMS) and athletic performance in female athletes. This study analyzed the relationships between FMS (deep squat; hurdle step [HS]; in-line lunge [ILL]; shoulder mobility; active straight-leg raise [ASLR]; trunk stability push-up; rotary stability) scores, and performance tests (bilateral and unilateral sit-and-reach [flexibility]; 20-m sprint [linear speed]; 505 with turns from each leg; modified T-test with movement to left and right [change-of-direction speed]; bilateral and unilateral vertical and standing broad jumps; lateral jumps [leg power]). Nine healthy female recreational team sport athletes (age = 22.67 ± 5.12 years; height = 1.66 ± 0.05 m; body mass = 64.22 ± 4.44 kilograms) were screened in the FMS and completed the afore-mentioned tests. Percentage between-leg differences in unilateral sit-and-reach, 505 turns and the jumps, and difference between the T-test conditions, were also calculated. Spearman's correlations (p ≤ 0.05) examined relationships between the FMS and performance tests. Stepwise multiple regressions (p ≤ 0.05) were conducted for the performance tests to determine FMS predictors. Unilateral sit-and-reach positive correlated with the left-leg ASLR (r = 0.704-0.725). However, higher-scoring HS, ILL, and ASLR related to poorer 505 and T-test performance (r = 0.722-0.829). A higher-scored left-leg ASLR related to a poorer unilateral vertical and standing broad jump, which were the only significant relationships for jump performance. Predictive data tended to confirm the correlations. The results suggest limitations in using the FMS to identify movement deficiencies that could negatively impact athletic performance in female team sport athletes. PMID:25729149

    It was reported in 1980s that ages at which peak performance was observed had remained remarkably stable in the past century, although absolute levels of athletic performance increased dramatically for the same time span. The emergence of older (masters) athletes in the past few decades has changed the demographics and age-spectrum of Olympic athletes. The primary aim of the present study was to determine whether the ages at which peak performance was observed had increased in the recent decades. The data spanning 114 years from the first Olympics (1898) to the most recent Olympics (2014) were collected using the publically available data. In the present study, ages at which Olympic medals (gold, silver, and bronze) were won were used as the indicators of peak performance age. Track and field, swimming, rowing, and ice skating events were analyzed. In men, peak performance age did not change significantly in most of the sporting events (except in 100 m sprint running). In contrast, peak performance ages in women have increased significantly since 1980s and consistently in all the athletic events examined. Interestingly, as women's peak performance age increased, they became similar to men's peak ages in many events. In the last 20-30 years, ages at which peak athletic performance is observed have increased in women but not in men.

    In this study, we used social cognitive career theory (Lent, Brown, & Hackett, 1994) to examine the development of female athletes' career interest in coaching and, specifically, the impact of contextual factors (female coaching role models, working hours, and perceived discrimination) on coaching self-efficacy and outcome expectations. Participants were 205 predominantly White, heterosexual female student athletes. A path analysis indicated that role models and working hours predicted coaching self-efficacy, which predicted coaching outcome expectations. Additionally, coaching self-efficacy, coaching outcome expectations, and contextual factors predicted coaching interest. Practical implications are discussed as well as suggestions for further research in this relatively unexplored area.

    The purpose of this study was to examine the effectiveness of maximal and rapid isometric torque characteristics of the hip extensor muscles and postural balance performance to discriminate between female collegiate soccer athletes and non-athlete controls. Ten athletes (mean ± SE: age = 19·20 ± 0·36 year; mass = 62·23 ± 3·12 kg; height = 162·43 ± 1·70 cm) and 10 non-athletes (age = 20·30 ± 0·40 year; mass = 69·64 ± 3·20 kg; height = 163·22 ± 2·10 cm) performed two isometric maximal voluntary contractions (MVCs) of the hip extensor muscles. Peak torque (PT) and absolute and relative rate of torque development (RTD) at early (0-50 ms) and late (100-200 ms) phases of muscle contraction were examined during each MVC. Postural balance was assessed using a commercially designed balance testing device, which provides a measurement of static stability based on sway index (SI). Results indicated that absolute and relative RTD at 0-50 ms (RTD50 and RTD50norm) were greater (P = 0·007 and 0·026), and postural SI was lower (P = 0·022) in the athletes compared with the non-athletes. However, no differences (P = 0·375-0·709) were observed for PT nor absolute and relative RTD at 100-200 ms (RTD100-200 and RTD100-200norm). Significant relationships were also observed between RTD50 and RTD50norm and SI (r = -0·559 and -0·521; P = 0·010 and 0·019). These findings suggest that early rapid torque characteristics of the hip extensor muscles and postural balance performance may be sensitive and effective measures for discriminating between college-aged athletes and non-athletes. Coaches and practitioners may use these findings as performance evaluation tools to help in identifying athletes with both superior early rapid torque and balance performance abilities, which may possibly be an indicator of overall athletic potential.

    Gravidity studies have intimated a relationship between serum relaxin levels and joint laxity. To assess its applicability to eumenorrheic athletes, weekly serum relaxin and knee arthrometry measurements were obtained in 57 collegiate women and 5 men for 4 consecutive weeks. The former included athletes, ACL-injured athletes, and nonathletes, while the latter formed an a priori hormonal control. Analysis of variance revealed a significant change in weekly serum relaxin levels in females but not in anterior translation. Regression analysis failed to disclose a relationship between these variables. Therefore, we conclude relaxin does not affect knee laxity.

  6. The New Policy on Hyperandrogenism in Elite Female Athletes is not about “Sex Testing”

    2012-01-01

    In April 2011, the International Olympic Committee (IOC) and the International Association of Athletic Federations (IAAF) updated their regulations regarding female elite athletes with hyperandrogenism: Females whose testosterone levels crossed into the male range could not compete with other females unless it is shown that they are resistant to the effects of testosterone. Although the new rule is a marked improvement over past attempts to ensure that males were not trying to compete as women in elite competition, there have been several criticisms leveled against the new regulations. Here we offer our reactions to claims that the new regulation promotes a sex-verification test, claims that intersex athletes will automatically be disqualified from competition, and proposals to either divide athletes based on variables beyond sex or completely eliminate sex groupings. Although elite sports can never achieve a perfect, level playing-field, there should be parameters within which athletes must adhere for a given sport. Yet, elite athletes themselves should play a decisive role in what is best for their sport. PMID:23320653

  7. Rationale and implementation of anterior cruciate ligament injury prevention warm-up programs in female athletes.

    2011-01-01

    The sex disparity in anterior cruciate ligament (ACL) injury risk and the subsequent adverse effects on knee joint health, psychosocial well-being, and financial costs incurred have produced a surge in research on risk factors and interventions designed to decrease this disparity and overall incidence. Biomechanical and neuromuscular differences have been identified throughout the trunk and lower extremity that may increase noncontact ACL injury risk in female athletes. Evidence demonstrates that many risk factors are modifiable with intervention programs and that athletic performance measures can be enhanced. No universally accepted ACL injury prevention program currently exists, and injury prevention programs are diverse. Anterior cruciate ligament injury prevention programs introduced in a warm-up format offer multiple benefits, primarily, improved compliance based on improved practicality of implementation. However, drawbacks of warm-up style formats also exist, most notably that a lack of equipment and resources may preclude measurable improvements in athletic performance that foster improved compliance among participants. The purpose of this review is to analyze the current literature researching possible biomechanical and neuromuscular risk factors in noncontact ACL injury in female athletes and the most effective means of implementing critical elements of a program to decrease ACL injury risk in female athletes while improving athletic performance. Hip and hamstring training, core stabilization, plyometrics, balance, agility, neuromuscular training with video and verbal feedback to modify technique, and stretching appear to be essential components of these programs. Further research is critical to determine ideal training program volume, intensity, duration, and frequency.

    Olympic weightlifting movements and their variations are believed to be among the most effective ways to improve power, strength, and speed in athletes. This study investigated the effects of two Olympic weightlifting variations (hang cleans and hang snatches), on power (vertical jump height), strength (1RM back squat), and speed (40-yard sprint) in female collegiate athletes. 23 NCAA Division I female athletes were randomly assigned to either a hang clean group or hang snatch group. Athletes participated in two workout sessions a week for six weeks, performing either hang cleans or hang snatches for five sets of three repetitions with a load of 80-85% 1RM, concurrent with their existing, season-specific, resistance training program. Vertical jump height, 1RM back squat, and 40-yard sprint all had a significant, positive improvement from pre-training to post-training in both groups (p≤0.01). However, when comparing the gain scores between groups, there was no significant difference between the hang clean and hang snatch groups for any of the three dependent variables (i.e., vertical jump height, p=0.46; 1RM back squat, p=0.20; and 40-yard sprint, p=0.46). Short-term training emphasizing hang cleans or hang snatches produced similar improvements in power, strength, and speed in female collegiate athletes. This provides strength and conditioning professionals with two viable programmatic options in athletic-based exercises to improve power, strength, and speed. PMID:27601779

    Background: Sports activities were thought to be the major cause of meniscus injury in both men and woman, but our observations of non-athletic females show that the cause of meniscus injury was unrelated to any type of sports activity. Objectives: This study revealed squat winnowing to be a major cause of meniscus injury in non-athletic females. Patients and Methods: This retrospective study was conducted in a tertiary care orthopaedic hospital which caters to a population of 10 million people. We assessed 120 non-athletic females who had received treatment in our hospital over a period of 2 years. The most probable cause of knee injury, per initial patient history, was recorded for all non-athletic females who presented clinical signs and symptoms of meniscus injury. The diagnoses were confirmed by relevant MRI and arthroscopy of patients’ knees. All females who engaged in athletic activity and other females with unrelated, non-traumatic knee pathologies were excluded from the study. Results: Through our study, we found that 42% (n = 50) of females suffered an injury during squat winnowing of rice, either at home or at work. Another 29% (n = 35) of females cited a history of slipping and spraining their knee as a cause of knee injury, while 19% (n = 16) of females suffered a knee injury during complex accidents such as a traffic accident. Finally, 13% (n = 16) of the females had no definite history of knee injury. Conclusions: Our observations add to the knowledge base of the various causes of meniscus tears; this study also revealed that socio-cultural factors influence and contribute to the mechanism of various types of knee injury.

    The aim was to analyse the physical growth and body composition of rhythmic gymnastics athletes relative to their level of somatic maturation. This was a cross-sectional study of 136 athletes on 23 teams from Brazil. Mass, standing height and sitting height were measured. Fat-free and fat masses, body fat percentages and ages of the predicted peak height velocity (PHV) were calculated. The z scores for mass were negative during all ages according to both WHO and Brazilian references, and that for standing height were also negative for all ages according to WHO reference but only until 12 years old according to Brazilian reference. The mean age of the predicted PHV was 12.1 years. The mean mass, standing and sitting heights, body fat percentage, fat-free mass and fat mass increased significantly until 4 to 5 years after the age of the PHV. Menarche was reached in only 26% of these athletes and mean age was 13.2 years. The mass was below the national reference standards, and the standing height was below only for the international reference, but they also had late recovery of mass and standing height during puberty. In conclusion, these athletes had a potential to gain mass and standing height several years after PHV, indicating late maturation.

    2014-01-01

    Post-activation potentiation (PAP) is a phenomenon in which the power output of a muscle is immediately enhanced after heavy resistance exercise. Whereas the majority of PAP research has examined males, minimal research exists as to how female athletes respond. Therefore, the purpose of this study was to investigate the acute PAP response of back squats on static squat jump (SSJ) performance among NCAA Division II female athletes. Female athletes (n=29) who were current roster members from basketball, softball, and volleyball, performed 3 SSJ prior to 3 repetitions of the back squat exercise at 90% 1RM. After a 5-min rest, athletes once again performed 3 SSJ for maximal height, with peak power calculated using the Sayers equation. There was a significant interaction effect observed between time and team, p=0.022; post-hoc tests indicated that the volleyball team had a significant decrease in power, p=0.008. The main effect for time was not significant, p=0.279, indicating for the group as a whole, there was no evidence of a PAP response. The main effect for team was also non-significant, p=0.173, indicating no difference in power outputs by team. Strength and conditioning coaches who work with female athletes should be aware that the successful implementation of PAP complexes within this population appears to be highly individualized. Therefore, the use of PAP complexes in female athletes should consider both the absolute and relative strength of each athlete in conjunction with the length of the rest period when attempting to optimize the PAP response.

    Baghbani, F, Woodhouse, LJ, and Gaeini, AA. Dynamic postural control in female athletes and nonathletes after a whole-body fatigue protocol. J Strength Cond Res 30(7): 1942-1947, 2016-Postural control is a crucial element in regular training of athletes, development of complex technical movement, and injury prevention; however, distributing factor of the postural control such as fatigue has been neglected by athletic trainers in novice and inexperienced athletes. The objective of this study was to compare changes in dynamic postural control of young female athletes and nonathletes after a fatigue protocol. Thirty females (15 athletes and 15 nonathletes) with no orthopedic problems were recruited to participate in this study. All participants completed the pre-SEBT (star excursion balance test) in 8 directions at baseline; then, they performed a 20-minute fatigue protocol after which post-SEBT was measured. Rating of perceived exertion was measured using the Borg scale immediately before, mid-way through (i.e., after the third station), and after performing the fatigue protocol (i.e., immediately before the post-SEBT). Female nonathlete groups had significant differences in dynamic balance performance after fatigue in the medial, posteromedial, and posterior directions (p < 0.01) measured by SEBT. Athletes, however, showed no significant changes after the fatigue protocol. Our results indicates the importance of evaluation and monitoring of dynamic postural control of the novice with progressing the exercise time. Our findings could also help coaches to develop trainings focused on the 3 directions of medial, posteromedial, and posterior directions and aimed at exercises increasing fatigue resistance.

    Female high school athletes are an at-risk population for the Female Athlete Triad-a syndrome including low energy availability (with or without disordered eating), menstrual dysfunction, and low bone mineral density. School nurses can play an important role in reducing the health burden of this syndrome, by educating coaches and athletes, and by referring symptomatic student-athletes to appropriate community resources for evaluation and treatment. This study assessed knowledge, attitudes, communication, and referral behaviors of U.S. high school nurses about the Female Athlete Triad. Participants were a random sample of 370 U.S. high school nurses. The results indicated that only 19% of the nurses were able to identify the three components of the Triad and only 25% reported that they work proactively with coaches to help prevent health issues among their female athletes. Over 95% expressed interest in learning more about the Triad. Implications for educational program design are discussed.

    In this paper, we report survival estimates for male and female Olympic medal winners and for male and female finalists at the British and U S national tennis championships. We find a consistent longevity advantage of Olympic medal-winning female athletes over Olympic medal-winning male athletes competing separately in the same events since 1900 and for female finalists over male finalists competing separately in the finals of the national tennis championships of Britain and of the United States since the 1880s. This is the case for sample mean comparisons, for Kaplan-Meier survival function estimates, including life expectancy, and for Cox proportional hazard estimates, which show statistically significant lower hazard rates for women with birth year and other variables constant. The female longevity advantage over males is similar in the early period samples (birth years before 1920) and in the full period samples, and is 5-7 years.

    Purpose To quantify the prevalence of biomechanical deficit patterns associated with ACL injury risk and their inter-connections in a large cohort of female athletes during an unanticipated cutting task. Methods High school female athletes (N=721) performed an unanticipated cutting task in the biomechanics laboratory. Trunk and lower extremity 3D kinetics and kinematics were measured and entered into a latent profile analysis model. Results Approximately 40% of female athletes demonstrated no biomechanical deficits and were categorized into the low risk group. The second most prevalent profile (24%) demonstrated a combination of high quadriceps and leg dominance deficits and was labeled as quadriceps-leg. The third most prevalent profile (22%) demonstrated a combination of trunk and leg dominance deficits and to lesser extent ligament dominance deficits, and was labeled as trunk-leg-ligament. Finally, the fourth profile (14%) demonstrated very high ligament dominance deficits only and it was labeled as ligament dominance profile. Conclusions This is the first study to identify the most common biomechanical profiles associated with ACL injury during a cutting task in a large cohort of female athletes. Approximately 60% of female athletes belong to one of the high-risk profiles. With the exception of the ligament dominance profile, the current analysis indicates that risk profiles consist of a combination of biomechanical deficits. The findings provide important insight into the prevalence of biomechanical deficits and future directions for the development of injury prevention programs. The findings can be used to guide the development of quick and easy tests that accurately categorize athletes into one of the profiles and subsequently prescribe tailored injury prevention programs that will be more effective and efficient than the current generic ones.

    Background The aims of this study were to determine the prevalence and incidence of patellofemoral pain (PFP) in young female athletes and prospectively evaluate measures of frontal plane knee loading during landing to determine their relationship to development of PFP. We hypothesized that increased dynamic knee abduction measured during preseason biomechanical testing would be increased in those who developed PFP relative to teammates who did not develop PFP. Methods Middle and high school female athletes (n=240) were evaluated by a physician for PFP and for landing biomechanics prior to their basketball season. The athletes were monitored for athletic exposures and PFP injury during their competitive seasons. Findings At the beginning of the season, the point prevalence of PFP was 16.3 per 100 athletes. The cumulative incidence risk and rate for the development of new unilateral PFP was 9.66 per 100 athletes and 1.09 per 1000 athletic exposures, respectively. All new PFP developed in middle school athletes who demonstrated mean International Knee Documentation Committee score of 85.6 ± 7.7 at diagnosis. The new PFP group demonstrated increased knee abduction moments at initial contact (95% CI: 0.32 to 4.62 Nm) on the most-symptomatic limb and maximum (95% CI: 1.3 to 10.1 Nm; p=0.02) on the least-symptomatic (or no symptoms) limb relative to the matched control limbs. Knee abduction moments remained increased in the new PFP group when normalized to body mass (p<0.05). Interpretation The increased knee abduction landing mechanics in the new PFP group indicate that frontal plane loads contribute to increased incidence of PFP. PMID:20466469

    Objective The primary aim of this paper was to investigate moderators and predictors of response to two programs designed to reduce eating disorder risk factors in collegiate female athletes. This study served as an ancillary study to a parent trial that investigated the feasibility of an athlete modified cognitive dissonance-based program (AM-DBP) and an athlete modified healthy weight intervention program (AM-HWI). Design 157 female collegiate athletes were randomized to either the AM-DBP or the AM-HWI program. Participants completed surveys at baseline, post-intervention, 6 weeks, and 1 year. Methods After classifying sports as either lean or non-lean, we investigated if sport type acted as a moderator of program response to AM-DBP and AM-HWI using ANOVAs. Next, we examined whether baseline thin-ideal internalization, weight concern, shape concern, bulimic pathology, dietary restraint, and negative affect acted as predictors of changes in bulimic pathology using linear regression models. Results Athletes in non-lean sports who received AM-DBP showed more improvement in negative affect versus non-lean sport athletes in AM-HWI. Higher baseline scores of bulimic pathology predicted greater response in bulimic pathology to both programs at 6-weeks. In contrast, athletes with higher dietary restraint and negative affect baseline scores showed decreased response to both interventions at 6-weeks. Finally, athletes with higher baseline shape concern showed a decreased response to the AM-HWI intervention at the post intervention time point. Conclusion Results from the present study indicate that lean/non-lean sport may not play a strong role in determining response to efficacious programs. Further, factors such as pre-existing bulimic pathology, dietary restraint, negative affect, and shape concern may affect general response to intervention versus specific responses to specific interventions.

    Previous research has identified that the second pull phase of the clean generates the greatest power output and that the midthigh variations of the power clean also result in the greatest force and power output in male athletes; however, no research has compared the kinetics of the variations of the power clean in women. The aim of this investigation was to identify any differences between variations of the clean, across a range of loads, in inexperienced female collegiate athletes. Sixteen healthy female collegiate athletes (age 19 ± 2.3 years; height 166.5 ± 3.22 cm; body mass 62.25 ± 4.52 kg; 1 repetition maximum [1RM] power clean 51.5 ± 2.65 kg) performed 3 repetitions of 3 variations (power clean, hang power clean, midthigh power clean) of the power clean at 60, 70, and 80% of their predetermined 1RM power clean, in a randomized and counterbalanced order. A 2-way analysis of variance (3 × 3; load × variation) revealed no significant differences (p > 0.05) in peak power, peak vertical force (Fz) or rate of force development (RFD) between loads or variations of the power clean. There appears to be no advantage in terms of peak power, Fz, or RFD between variations of the clean, in inexperienced female athletes, it is suggested, therefore, that inexperienced athletes intermittently perform different variations of the clean to ensure all round development and technical competence in each variation of the exercise.

  1. Physiological and nutritional aspects of post-exercise recovery: specific recommendations for female athletes.

    2011-10-01

    Gender-based differences in the physiological response to exercise have been studied extensively for the last four decades, and yet the study of post-exercise, gender-specific recovery has only been developing in more recent years. This review of the literature aims to present the current state of knowledge in this field, focusing on some of the most pertinent aspects of physiological recovery in female athletes and how metabolic, thermoregulatory, or inflammation and repair processes may differ from those observed in male athletes. Scientific investigations on the effect of gender on substrate utilization during exercise have yielded conflicting results. Factors contributing to the lack of agreement between studies include differences in subject dietary or training status, exercise intensity or duration, as well as the variations in ovarian hormone concentrations between different menstrual cycle phases in female subjects, as all are known to affect substrate metabolism during sub-maximal exercise. If greater fatty acid mobilization occurs in females during prolonged exercise compared with males, the inverse is observed during the recovery phase. This could explain why, despite mobilizing lipids to a greater extent than males during exercise, females lose less fat mass than their male counterparts over the course of a physical training programme. Where nutritional strategies are concerned, no difference appears between males and females in their capacity to replenish glycogen stores; optimal timing for carbohydrate intake does not differ between genders, and athletes must consume carbohydrates as soon as possible after exercise in order to maximize glycogen store repletion. While lipid intake should be limited in the immediate post-exercise period in order to favour carbohydrate and protein intake, in the scope of the athlete's general diet, lipid intake should be maintained at an adequate level (30%). This is particularly important for females specializing in

    Context Anterior cruciate ligament (ACL) injury is a major concern in physically active females. Although ACL reconstruction techniques have seen significant advances in recent years, risk associated with re-injury and future osteoarthritis remains a major concern. Thus, prevention of ACL injury is a logical step to protect and preserve healthy knee joints in young athletes. The current report aims to summarize a list of evidence-based prevention strategies to reduce ACL injury in female athletes. A list of six critical principles, which come from documented, large scale clinical trial studies and further analyses, were presented with ABC format including age, biomechanics, compliance, dosage, exercise, and feedback. Also, a grade for evidence and implications of future research is noted. Finally, in the conclusion section, importance of collaborative efforts from healthcare practitioners, researchers, and personnel associated with athletics is addressed. PMID:26042191

    The purpose of this study was to assess dietary intake and body composition of prepubescent girls competing in 3 aesthetic sports (artistic and rhythmic gymnastics and ballet). Because physiological demands of ballet training are similar to those in other aesthetic sports, ballet dancers were, for the purpose of this study, regarded as athletes. The sample consisted of 39 athletes (median age, 11 years, range 9-13) and 15 controls (median age, 11 years, range 10-12). Dietary intake was assessed using a quantitative food frequency questionnaire, and body composition, by means of anthropometry. There was no significant difference in total energy intake between groups, but there was a significant difference in energy substrate distribution. Artistic gymnasts reported significantly higher carbohydrate and lower fat contribution to total energy (57% +/- 6% and 29% +/- 5%, respectively) than rhythmic gymnasts (48% +/- 6% and 36% +/- 5%), ballet dancers (51% +/- 4% and 34% +/- 3%), or controls (51% +/- 5% and 34% +/- 4%). Relative to body weight, artistic gymnasts reported higher intake of carbohydrates (9.1 +/- 4.2 g/kg) than rhythmic gymnasts (5.6 +/- 3.1 g/kg), ballet dancers (6.6 +/- 2.5 g/kg), or controls (5.4 +/- 1.9 g/kg). Artistic gymnasts also had the lowest body-fat percentage among the groups. In all the groups mean reported daily intakes of most nutrients were higher than the current daily recommended intakes. The exceptions were dietary fiber and calcium. The proportion of athletes with an inadequate reported intake was highest for phosphorus (33%), followed by vitamin A and niacin (18%) and zinc (13%).

    The article presents the morphogenetic performance of 31 female athlete aged 18-23 years specializing in fencing, compared to women of the same age group not involved in professional sports. The research program included: evaluation of a complex of anthropometric parameters (longitudinal, transverse, circumferential body sizes), somatotype diagnostics using of Heath-Carter method, evaluation of body composition, qualitative and quantitative characteristics of digital dermatoglyphics (pattern type, ridge count, delta index, a combination of phenotypic patterns), determination of sex chromatin content in the epithelial cells of the oral cavity mucous membrane. The study demonstrated that the somatic status of female fencers could be defined as a balanced mesomorphic somatotype with the prevailing mesomorphic vector. The proportion of muscular component in female athletes was higher, while that of the fat mass was lower than the similar parameters in the control group. The athletes were characterized by the peculiarities of dermatoglyphic constitution: high values of delta index and the total ridge count, higher proportion of complex patterns and minimal amount of simple patterns. In female athletes, significantly lower amounts of sex chromatin were demonstrated as compared to those not engaged in sports.

    The incidence of anterior cruciate ligament (ACL) injury remains high in young athletes. Because female athletes have a much higher incidence of ACL injuries in sports such as basketball and team handball than male athletes, the IOC Medical Commission invited a multidisciplinary group of ACL expert clinicians and scientists to (1) review current evidence including data from the new Scandinavian ACL registries; (2) critically evaluate high-quality studies of injury mechanics; (3) consider the key elements of successful prevention programmes; (4) summarise clinical management including surgery and conservative management; and (5) identify areas for further research. Risk factors for female athletes suffering ACL injury include: (1) being in the preovulatory phase of the menstrual cycle compared with the postovulatory phase; (2) having decreased intercondylar notch width on plain radiography; and (3) developing increased knee abduction moment (a valgus intersegmental torque) during impact on landing. Well-designed injury prevention programmes reduce the risk of ACL for athletes, particularly women. These programmes attempt to alter dynamic loading of the tibiofemoral joint through neuromuscular and proprioceptive training. They emphasise proper landing and cutting techniques. This includes landing softly on the forefoot and rolling back to the rearfoot, engaging knee and hip flexion and, where possible, landing on two feet. Players are trained to avoid excessive dynamic valgus of the knee and to focus on the "knee over toe position" when cutting.

    2009-05-01

    The present study investigated whether moderate, organized physical activity during high school has a positive residual effect on bone mineral density (BMD) in 30-35-year-old females. Seventy-three female former high-school varsity athletes and 67 self-reported low-activity age-matched controls completed a collegiate women's health survey and participated in a one-time clinical visit with bone scan. Lumbar (L1-L4) spine BMD, total hip BMD, percentage body fat, age at menarche, history of amenorrhea, family history of osteoporosis, college alcohol consumption, number of high school varsity seasons, as well as current nutritional intake (including calcium), number of weekly weight training sessions, and caloric expenditure were assessed. Using a saturated linear regression model, current percentage body fat and number of high school seasons predicted 22% of the observed variation in total hip BMD and 25% of the observed variation of lumbar (L1-L4) spine BMD (P<0.001). High school athletes were more likely to be frequent adult exercisers (P<0.001). Athletic participants were more likely to have denser hip and spine bones than low-activity controls. Results suggest that participation in high school athletics is associated with greater BMD. Additionally, the varsity athletes continued to exercise frequently in their early 30s.

    Vitamin D (VD) insufficiency is a concern, particularly among young females. The VD status shows seasonal variations, since it correlates with duration of sunlight exposure. VD insufficiency in indoor athletes is therefore suggested in winter. The aim of the present study was to determine seasonal variations in VD and bone status among indoor and outdoor female athletes. The prospective study was conducted in participants aged 20–22 years old. The participants comprised of 15 indoor and 15 outdoor athletes. The biochemical markers and bone parameters were measured in March, June, September and December. The serum 25-hydroxyvitamin D (25-OH-VD) concentration showed a seasonal oscillation, with a nadir in March (indoor, 19±4.0 ng/ml; outdoor, 32±2.7 ng/ml) and a peak in September (indoor, 32±6.6 ng/ml; outdoor, 39±5.7 ng/ml). The amplitude of oscillation was greater in the indoor compared to the outdoor athletes. Seasonal variations in serum calcium exhibited a similar pattern, while the parathyroid hormone showed an inverse pattern to serum 25-OH-VD. The nadir in bone mass, measured as speed of sound, occurred in June after peaking in December among the indoor and outdoor athletes. The pattern followed 3 months after the changes in 25-OH-VD. Indoor sports athletes are more susceptible to VD insufficiency compared to outdoor sports athletes. Insufficiency is most likely to arise in winter, and could affect bone mineralization observed 3 months after. PMID:27347414

    Eberman, Lindsey E; Cleary, Michelle A

    2005-01-01

    Objective: To present the case of an elite female volleyball player who complained of diarrhea and fatigue after preseason training. Background: The athlete lost 8.1 kg during the first 20 days of training, and we initially suspected an eating disorder. The sports medicine team interviewed the athlete and found she did not have psychological symptoms indicative of an eating disorder. The results of routine blood tests revealed critically high platelet counts; in conjunction with the physical findings, the athlete was referred to a gastroenterologist. Differential Diagnosis: Our initial suggestion was an eating disorder. Therefore, the differential diagnosis included anorexia athletica, anorexia nervosa, and bulimia nervosa. On referral, the differential diagnosis was anemia, gastrointestinal dysfunction, lymphoma, or bowel adenocarcinoma. Diarrhea, weight loss, and blood test results were suggestive of active celiac disease, and a duodenal biopsy specimen confirmed this diagnosis. Treatment: The athlete was treated with a gluten-free diet, which excludes wheat, barley, and rye. Dietary substitutions were incorporated to maintain adequate caloric intake. Uniqueness: The presence of active celiac disease may not be uncommon. However, elite athletes who face celiac disease present a new challenge for the athletic trainer. The athletic trainer can help guide the athlete in coping with the lifestyle changes associated with a gluten-free diet. Conclusions: One in every 200 to 400 individuals has celiac disease; many of these individuals are asymptomatic and, therefore, their conditions are undiagnosed. Undiagnosed, untreated celiac disease and patients who fail to follow the gluten-free diet increase the risk of further problems. PMID:16404459

    Context Female athletic trainers (ATs) experience gender discrimination in the workplace due to stereotypical gender roles, but limited information is available regarding the topic. Objective To understand the challenges and obstacles faced by young female ATs working in National Collegiate Athletic Association Division I athletics. Design Exploratory study using semistructured interviews. Setting Division I clinical setting. Patients or Other Participants A total of 14 female ATs were included in the study, using both criterion and snowball- sampling techniques. Their mean age was 27 ± 2 years, with 5 ± 2 years of overall clinical experience. Criteria included employment at the Division I clinical setting, being a full-time assistant AT, and at least 3 years of working experience but no more than 9 years to avoid role continuance. Data Collection and Analysis Analysis of the interview data followed inductive procedures as outlined by a grounded theory approach. Credibility was established by member checks, multiple-analyst triangulation, and peer review. Results Clear communication with both coaches and players about expectations and philosophies regarding medical care, a supportive head AT in terms of clinical competence, and having and serving as a role model were cited as critical tools to alleviate gender bias in the workplace. Conclusions The female ATs in this study stressed the importance of being assertive with coaches early in the season with regard to the AT's role on the team. They reasoned that these actions brought forth a greater perception of congruity between their roles as ATs and their gender and age. We suggest that female athletic training students seek mentors in their field while they complete their coursework and practicums. The ATs in the current study indicated that a mentor, regardless of sex, helped them feel empowered to navigate the male-centric terrain of athletic departments by encouraging them to be assertive and not second

    Maintaining low body weight for the sake of performance and aesthetic purposes is a common feature among young girls and women who exercise on a regular basis, including elite, college and high-school athletes, members of fitness centres, and recreational exercisers. High energy expenditure without adequate compensation in energy intake leads to an energy deficiency, which may ultimately affect reproductive function and bone health. The combination of low energy availability, menstrual disturbances and low bone mineral density is referred to as the 'female athlete triad'. Not all athletes seek medical assistance in response to the absence of menstruation for 3 or more months as some believe that long-term amenorrhoea is not harmful. Indeed, many women may not seek medical attention until they sustain a stress fracture. This review investigates current issues, controversies and strategies in the clinical management of bone health concerns related to the female athlete triad. Current recommendations focus on either increasing energy intake or decreasing energy expenditure, as this approach remains the most efficient strategy to prevent further bone health complications. However, convincing the athlete to increase energy availability can be extremely challenging. Oral contraceptive therapy seems to be a common strategy chosen by many physicians to address bone health issues in young women with amenorrhoea, although there is little evidence that this strategy improves bone mineral density in this population. Assessment of bone health itself is difficult due to the limitations of dual-energy X-ray absorptiometry (DXA) to estimate bone strength. Understanding how bone strength is affected by low energy availability, weight gain and resumption of menses requires further investigations using 3-dimensional bone imaging techniques in order to improve the clinical management of the female athlete triad.

    The female athlete triad (Triad) refers to the interrelationships among energy availability, menstrual function, and bone mineral density, which may have clinical manifestations including eating disorders, functional hypothalamic amenorrhea, and osteoporosis. With proper nutrition, these same relationships promote robust health. Athletes are distributed along a spectrum between health and disease, and those at the pathological end may not exhibit all these clinical conditions simultaneously. Energy availability is defined as dietary energy intake minus exercise energy expenditure. Low energy availability appears to be the factor that impairs reproductive and skeletal health in the Triad, and it may be inadvertent, intentional, or psychopathological. Most effects appear to occur below an energy availability of 30 kcal.kg(-1) of fat-free mass per day. Restrictive eating behaviors practiced by girls and women in sports or physical activities that emphasize leanness are of special concern. For prevention and early intervention, education of athletes, parents, coaches, trainers, judges, and administrators is a priority. Athletes should be assessed for the Triad at the preparticipation physical and/or annual health screening exam, and whenever an athlete presents with any of the Triad's clinical conditions. Sport administrators should also consider rule changes to discourage unhealthy weight loss practices. A multidisciplinary treatment team should include a physician or other health-care professional, a registered dietitian, and, for athletes with eating disorders, a mental health practitioner. Additional valuable team members may include a certified athletic trainer, an exercise physiologist, and the athlete's coach, parents and other family members. The first aim of treatment for any Triad component is to increase energy availability by increasing energy intake and/or reducing exercise energy expenditure. Nutrition counseling and monitoring are sufficient

    BACKGROUND/OBJECTIVES The purpose of this study was to assess the accuracy of a dietary reference intake (DRI) predictive equation for estimated energy requirements (EER) in female college tennis athletes and non-athlete students using doubly labeled water (DLW) as a reference method. MATERIALS/METHODS Fifteen female college students, including eight tennis athletes and seven non-athlete subjects (aged between 19 to 24 years), were involved in the study. Subjects' total energy expenditure (TEE) was measured by the DLW method, and EER were calculated using the DRI predictive equation. The accuracy of this equation was assessed by comparing the EER calculated using the DRI predictive equation (EERDRI) and TEE measured by the DLW method (TEEDLW) based on calculation of percentage difference mean and percentage of accurate prediction. The agreement between the two methods was assessed by the Bland-Altman method. RESULTS The percentage difference mean between the methods was -1.1% in athletes and 1.8% in non-athlete subjects, whereas the percentage of accurate prediction was 37.5% and 85.7%, respectively. In the case of athletic subjects, the DRI predictive equation showed a clear bias negatively proportional to the subjects' TEE. CONCLUSIONS The results from this study suggest that the DRI predictive equation could be used to obtain EER in non-athlete female college students at a group level. However, this equation would be difficult to use in the case of athletes at the group and individual levels. The development of a new and more appropriate equation for the prediction of energy expenditure in athletes is proposed. PMID:28194265

    Knee injuries are highly prevalent in athletic populations, particularly among female athletes. Many of these injuries occur during landing from a jump. Various comprehensive knee injury prevention programs have been developed to date. However, there is a need to determine which components of these programs contribute directly to changes in knee biomechanics. Therefore, the purpose of this study was to investigate the immediate effect of three different simple verbal instructions on knee biomechanics during landing in adult female recreational athletes. Three-dimensional kinematic and kinetic analysis of landing from a countermovement jump was conducted in a counterbalanced cross-over repeated measures design. Results indicated that the instruction to land with equal weight distribution reduced the asymmetry of peak vertical ground reaction force compared to the control condition. The instruction to land softly reduced peak vertical ground reaction force and increased peak knee flexion compared to the control condition. The instruction to land with knees over toes increased peak knee flexion compared to the control condition. These findings indicate that verbal instruction may be a key component of the effects seen in previous research studies that have investigated the benefits of more complex training programs designed to reduce knee injury risk in female athletes.

    Objectives: Female soccer athletes have a three-fold greater risk of sustaining an ACL injury compared with their male counterparts yet only 1 in 5 teams engage in ACL risk reduction programs due to several participation barriers. The purpose of this study was to determine the effects of a wearable neuromuscular (WNM) device on postural control, performance and ACL injury risk in female soccer athletes. Methods: Seventy-nine elite youth and collegiate female soccer athletes (age range: 12-25 y) trained with a WNM device that applied bi-lateral, topical pressure to the medial quadriceps and hamstrings muscles (Topical Gear, Austin, TX). The athletes performed 7-9 weeks of pre-season training with the WNM device consisting of strength and conditioning exercises and on-field team practices (46-64 total hours of exposure). Postural control was measured in 15 athletes with and without the WNM device before and after the training program; and performance was measured in 25 athletes without the WNM device before and after the training program. Postural control was determined from a single-leg landing on a force plate from a horizontal distance normalized to leg length. The athletes were instructed to gain their balance as fast as possible upon landing and remain balanced for 5 seconds. The peak ground reaction forces (GRF) and the medial-lateral, anterior-posterior and net center of pressure (COP) velocities and displacement ranges were calculated during 2 seconds of single-leg stance. Performance measures including speed, power and endurance were measured from the 40 yard dash, vertical jump for height and the Beep test, respectively. A two-way repeated measures ANOVA and post-hoc comparisons were used to compare the postural variables; and t-tests were used to compare the performance tests (p=.05). ACL injury rates, the absolute risk reduction (ARR) and the number needed to treat (NNT) to prevent one ACL injury were calculated between the WNM intervention group and 11

    Core stability training (CST) has increased in popularity among athletes and the general fitness population despite limited evidence CST programmes alone lead to improved athletic performance. In female athletes, neuromuscular training combining balance training and trunk and hip/pelvis dominant CST is suggested to reduce injury risk, and specifically peak vertical ground reaction forces (vGRF) in a drop jump landing task. However, the isolated effect of trunk dominant core stability training on vGRF during landing in female athletes had not been evaluated. Therefore, the objective of this study was to evaluate landing kinetics during a drop jump test following a CST intervention in female capoeira athletes. After giving their informed written consent, sixteen female capoeira athletes (mean ± SD age, stature, and body mass of 27.3 ± 3.7 years, 165.0 ± 4.0 cm, and 59.7 ± 6.3 kg, respectively) volunteered to participate in the training program which consisted of static and dynamic CST sessions, three times per week for six weeks. The repeated measures T-test revealed participants significantly reduced relative vGRF from pre- to post-intervention for the first (3.40 ± 0.78 vs. 2.85 ± 0.52 N·NBW-1, respectively [p<0.05, effect size = 0.60]), and second landing phase (5.09 ± 1.17 vs. 3.02 ± 0.41 N·NBW-1, respectively [p<0.001, effect size = 0.87]). The average loading rate was reduced from pre- to post-intervention during the second landing phase (30.96 ± 18.84 vs. 12.06 ± 9.83 N·NBW·s-1, respectively [p<0.01, effect size = 0.68]). The peak loading rate was reduced from pre- to post-intervention during the first (220.26 ± 111.51 vs. 120.27 ± 64.57 N·NBW·s-1 respectively [p<0.01, effect size = 0.64]), and second (99.52 ± 54.98 vs. 44.71 ± 30.34 N·NBW·s-1 respectively [p<0.01, effect size = 0.70]) landing phase. Body weight, average loading rate during the first landing phase, and jump height were not significantly different between week 0 and week 6

    This report presents a case of a displaced stress fracture of the femoral neck in an adolescent female distance runner with amenorrhea. Both reduction and internal fixation were performed early after the injury. At 24 months postoperatively, magnetic resonance imaging and bone scintigraphy showed no positive signs of femoral head necrosis and bone union was confirmed on plain X-ray. A medical examination for the presence of the signs of the female athlete triad by checking weight, calorie intake and menstrual cycles is most important to prevent such stress fractures. Athletes as well as their coaches or parents therefore need to understand female athlete triad.

    Background and Aim Recent studies revealed a link between hypovitaminosis D3 and the risk for hyperglycemia. Further mechanistic and interventional investigations suggested a common reason for both conditions rather than a causal relationship. Exposure to sunlight is the most relevant source of vitamin D3 (25(OH)D), whereas adipose tissue is able to store relevant amounts of the lipophilic vitamin. Since running/bicycling leads to increased out-door time and alters physiological response mechanisms, it can be hypothesized that the correlation between hypovitaminosis D3 and hyperglycemia might be disturbed in outdoor athletes. Methods 47 elderly marathoners/bicyclists and 47 age/sex matched controls were studied in a longitudinal setting at baseline and after three years. HbA1c as a surrogate for (pre-)diabetic states was quantified via HPLC, 25(OH)D levels were measured by means of chemiluminescent assays. Physical performance was assessed by ergometry. Results When adjusted for seasonal variations, 25(OH)D was significantly higher in athletes than in controls. 25(OH)D levels inversely correlated with triglycerides in both groups, whereas only in controls an association between high BMI or low physical performance with hypovitaminosis D3 had been found. Likewise, the presence of hypovitaminosis D3 at baseline successfully predicted hyperglycemia at the follow up examinations within the control group (AUC = 0.85, 95% CI [0.74, 0.96], p < .001, statistically independent from BMI), but not in athletes. Conclusion Our data suggest that mechanisms of HbA1c elevation might differ between athletes and controls. Thus, intense physical activity must be taken into account as a potential pre-analytic confounder when it is aimed to predict metabolic risk by vitamin D3 levels. PMID:27304888

    This paper compares the prevalence of sexual harassment and abuse among 660 Norwegian elite female athletes and an age-matched control sample of nonathletes. It also explores differences in the prevalence of harassment and abuse in sport and work or school settings and compares harassment and abuse perpetrated by male authority figures and peers in these different contexts. No differences were found between the athletes and controls in overall prevalence of sexual harassment or abuse. However, the athletes experienced significantly more harassment from male authority figures than did the controls. Based on these results, the article considers whether or not sport offers women any particular immunity from sexual harassment and abuse. The implications of the findings for structural and cultural change in sport are discussed.

    With female collegiate athletes, we examined the relationship of eating pathology to body image concerns, weight pressures, sociocultural internalization, and mood state. Multivariate analyses revealed that the symptomatic and eating disorder groups were similar on seven of eight weight pressures, three of four mood states, on internalization, and on five of six body image measures; in all instances, these two groups reported more pathological scores than the asymptomatic athletes. Except for pressures from coaches, the psychosocial variables differentiated the groups, correctly classifying 79% of the cases. These findings suggest that athletes symptomatic of eating disorders report similarly high levels of disturbance across a wide range of psychosocial risk factors, and both groups warrant prevention and treatment efforts.

    Bidirectional, longitudinal relations between alcohol and marijuana use and prosocial behaviors in women college student athletes were examined. Participants were 187 female college students (Mage = 19.87 years; 91% White) who completed questionnaires on their use of marijuana and alcohol, and six forms of prosocial behaviors across 6 years (2004-2010). The findings yield overall evidence that earlier marijuana use predicted lower levels of most specific forms of prosocial behaviors for women athletes in later young adulthood. Early expressions of altruistic behaviors predicted less marijuana use in later young adulthood. Expression of public prosocial behaviors early in young adulthood predicted higher levels of hazardous drinking in late young adulthood. These novel findings have important implications for links between prosocial development and substance use in women college athletes.

    Objective To identify psychological and physiological correlates of stress fracture in female endurance athletes. Design A cross-sectional design was used with a history of stress fractures and potential risk factors assessed at one visit. Methods Female-endurance athletes (58 runners and 12 triathletes) aged 26.0±7.4 years completed questionnaires on stress fracture history, menstrual history, athletic training, eating psychopathology and exercise cognitions. Bone mineral density, body fat content and lower leg lean tissue mass (LLLTM) were assessed using dual-x-ray absorptiometry. Variables were compared between athletes with a history of stress fracture (SF) and those without (controls; C) using χ², analysis of variance and Mann-Whitney U tests. Results Nineteen (27%) athletes had previously been clinically diagnosed with SFs. The prevalence of current a/oligomenorrhoea and past amenorrhoea was higher in SF than C (p=0.008 and p=0.035, respectively). SF recorded higher global scores on the eating disorder examination questionnaire (p=0.049) and compulsive exercise test (p=0.006) and had higher LLLTM (p=0.029) compared to C. These findings persisted with weight and height as covariates. In multivariate logistic regression, compulsive exercise, amenorrhoea and LLLTM were significant independent predictors of SF history (p=0.006, 0.009 and 0.035, respectively). Conclusions Eating psychopathology was associated with increased risk of SF in endurance athletes, but this may be mediated by menstrual dysfunction and compulsive exercise. Compulsive exercise, as well as amenorrhoea, is independently related to SF risk. PMID:23166136

    Objective To propose the inclusion of a gynecological investigation during the evaluation of athletes before competitions, using a specific instrument called the Pre-participation Gynecological Examination (PPGE). Methods The study assessed 148 athletes, mean age of 15.4±2.0 years, who engaged in eight different sports modalities, and who responded to a questionnaire named Pre-Participation Gynecological Examination (PPGE), to the International Consultation on Incontinence Questionnaire - Short Form (for urinary loss), and to the Eating Attitudes Test (for eating disorders). Results Fifty percent of the participants reported irregular menstrual intervals, 23.0% did not know about sexually transmitted diseases, and 72.4% denied having, at least, an annual gynecological appointment. The study identified 18.2% who had urinary loss, and 15% presented with an increased risk of eating disorders. Moreover, 89.9% were not familiar with the occurrence of urinary incontinence in athletes and did not know that they were susceptible to the female athlete triad. A total of 87.1% of them stated that would not mention these issues to their coaches even if this would improve their health or performance. Conclusion The Pre-Participation Gynecological Examination can be considered an easy-to-apply instrument that allowed the diagnosis of alterations often underestimated by the athletes themselves. After its application, the alterations were identified, and determined the athletes’ referral to appropriate evaluation and treatment. PMID:25628197

    2003-10-01

    Iron deficiency is probably the most common nutrient deficiency in the western world. Low levels of iron in the body are caused by several mechanisms, and become symptomatic with the onset of iron deficiency anemia. Athletes are a special group with additional reasons for iron or blood loss, such as plasma expansion, increase perspiration, 'foot strike hemolysis, and occasionally--malnutrition. Female athletes have yet another source of blood loss--menstruation. However, the most common cause for low hemoglobin levels in an athlete is dilutional pseudoanemia, which is caused by exercise-induced fluid retention. Athletes are more sensitive to the effects of anemia and iron deficiency, as exercise performance depends on maximal oxygen carrying capacity to the active muscle, and efficient oxygen utilization. Iron deficiency without anemia can also reduce athletic performance. Diagnosis is ultimately made by a blood count and red blood cell parameters, with ferritin serving as an index of body iron stores. Treatment requires iron supplements, as it is nearly impossible to refill the iron stores through diet alone.

    The purpose of this study was to compare plasma leptin, plasma zinc, and plasma copper levels and their relationship in trained female and male judo athletes (n = 10 women; n = 8 men). Blood samples were obtained 24 h after training to measure plasma zinc, copper, and leptin levels. Subjects presented similar values to age (22 +/- 2 years old), body mass index (24 +/- 1 kg/m(2)), plasma zinc (17.2 +/- 2 micromol/L), copper (12.5 +/- 2 micromol/L), and leptin (5.6 +/- 1.3 microg/L). However, height, total body mass, lean mass, fat mass, and sum of ten-skinfold thickness were higher in male than female. Plasma leptin was associated with sum of ten skinfolds in male (r = 0.91; p < 0.001) and female athletes (r = 0.84; p < 0.003). Plasma zinc was associated with leptin in males (r = 0.82; p < 0.05) while copper was associated with plasma leptin in females (r = 0.66; p < 0.05). Our results suggest that young judo athletes lost sex-related differences in leptin levels. Plasma zinc, plasma copper, and energy homeostasis may be involved in regulation of plasma leptin.

    Women with increased risk of the female athlete triad (Triad) are more susceptible to osteoporosis compared to other women. The study included 65 women with increased risk of the Triad who had their osteoporosis health beliefs measured to assess their concern for the disease. Participants were female collegiate cross-country runners at different levels of competition, including National Association of Intercollegiate Athletics (NAIA) and National Collegiate Athletic Association (NCAA) Divisions III, II, and I. Although these participants have an increased risk of the Triad and are more susceptible to osteoporosis, on a scale of 1 to 5, results showed that they had low to moderate perceived susceptibility to osteoporosis with a mean score as high as 2.81 and moderate perceived severity of osteoporosis with a mean score as high as 3.38. A statistically significant difference in perceived susceptibility to osteoporosis was found between female collegiate cross-country runners in the NAIA and those in the NCAA DIII. Reasons that could explain relatively low levels of concern for osteoporosis in female collegiate cross-country runners and reasons for significant differences in perceived susceptibility to osteoporosis are given, and recommendations for health education and intervention to help care for this population are provided.

Although these participants have an increased risk of the Triad and are more susceptible to osteoporosis, on a scale of 1 to 5, results showed that they had low to moderate perceived susceptibility to osteoporosis with a mean score as high as 2.81 and moderate perceived severity of osteoporosis with a mean score as high as 3.38. A statistically significant difference in perceived susceptibility to osteoporosis was found between female collegiate cross-country runners in the NAIA and those in the NCAA DIII. Reasons that could explain relatively low levels of concern for osteoporosis in female collegiate cross-country runners and reasons for significant differences in perceived susceptibility to osteoporosis are given, and recommendations for health education and intervention to help care for this population are provided.

    Menstrual disorders are common among female athletes and ballet dancers. Endocrine changes, such as high testosterone (HT) levels and high luteinizing hormone (LH)/follicle-stimulating hormone (FSH) ratios, may suggest functional ovarian hyperandrogenism which may induce such dysfunction. The aim of this study was therefore to evaluate endocrine status in female athletes and ballet dancers with menstrual disorders. Their nutritional status and dietary habits were analysed in relation to the testosterone levels. In a cross-sectional approach, 31 female athletes (18.1 ± 2.6 years) and 21 ballerinas (17.1 ± 0.9) with menstrual disorders participated in the study. The levels of serum LH, FSH, progesterone (P), estradiol (E2), prolactin (PRL), thyroid-stimulating hormone, testosterone (T) and sex hormone-binding globulinwere measured to assess hormonal status. In addition, the free androgen index (FAI) was calculated. Nutritional status, total daily energy expenditure and nutritional habits were evaluated. Girls were assigned to one of the following groups: low testosterone (LT) level, normal testosterone level or HT level. There were significant differences between ballerinas and other female athletes in terms of testosterone levels, FAI, age at the beginning of training, length of training period and age at menarche. The PRL level was lowest in the LT group while the FAI index was highest in the HT group. Daily energy and carbohydrate intakes were significantly lower in the HT group. T levels in the study subjects were found to be associated with nutritional factors, energy availability, age at the beginning of training and frequency of training. This is the first report of HT levels being associated with the status of a female ballet dancer, the age of menarche and the length of the training history. Further research is necessary to confirm the results in a larger study group.

    Studies have reported the benefits of pre-cooling prior to exercise in the heat for male athletes, but at this time no research has investigated female athletes. The aim of the following study was to test the effects of pre-cooling on female repeat sprint performance in hot, humid conditions; namely is ice ingestion effective in reducing core temperature (Tc) and does this reduced Tc lead to improved repeat sprint performance in female athletes? Nine female team sport athletes with mean age (21.0 ± 1.2 y), height (169.8 ± 4.1 cm) and body mass (62.3 ± 5.0 kg) participated in this study. Participants completed 72 min of an intermittent sprint protocol (ISP) consisting of 2 × 36 min halves in hot, humid conditions (33.1 ± 0.1 °C, 60.3 ± 1.5% RH) on a cycle ergometer. This was preceded by 30 min of either ice ingestion (ICE) or water consumption (CON) in a randomised order. At the end of the pre-cooling period, Tc significantly decreased following ICE (-0.7 ± 0.3 °C) compared to CON (-0.1 ± 0.2 °C; p = 0.001). Tc also remained lower in ICE compared to CON during the ISP (p = 0.001). Ratings of perceived thermal sensation were lower in ICE compared to CON (p = 0.032) at the beginning (p = 0.022) and mid-point (p = 0.035) of the second half. No differences in work, mean power, peak power, rating of perceived exertion, heart rate or sweat loss between conditions were recorded (p > 0.05). Ice ingestion significantly reduced female Tc prior to intermittent exercise in the heat and reduced thermal sensation; however, this did not coincide with improved performance.

    Stress fractures occur in normal bone due to mechanical overload by cyclic stress increasing the osteoclastic activity, thus facilitating weakening leading to fracture of bones. Long-distance running may lead to stress fractures of the mid- and distal tibia and of the metatarsal bones. Stress fractures to the sacrum are rare. Certain factors for stress fractures in runners have been identified, such as leg-length inequality, a high longitudinal arch of the foot, forefoot varus, and menstrual irregularities in case of female athlete triad. We report on a 22-year-old female runner (usually training 140 km/week) suffering a sacral fatigue-type fracture. The female athlete triad with eating disorders, dysmenorrhea, and osteopenia was ruled out. Sexual hormone blood samples proofed normal values. The diagnosis was performed using magnetic resonance imaging 2 weeks after the onset of buttock pain. A conservative treatment regimen was initiated with strict physical rest for the first 2 weeks, and then gradual increase of physical activity with 60-90 min of daily cycling and moderate 2 x 60 min cross-training. After another 2 weeks time, daily 60-90 min of walking, Nordic pole walking, and moderate strength training two times a week was performed. At 7 weeks running was started, gradually increased to 90 km/week without any pain. A rapid rehabilitation programme after sacral stress fractures involving low impact physical activity, such as Walking and Nordic pole walking, is applicable to female athletes after ruling out the female athlete triad.

    OBJECTIVE--To study the effects of amenorrhoea and intensive back exercise on the bone mineral density of the lumbar spine in female athletes. DESIGN--Cross sectional study comparing amenorrhoeic with eumenorrhoeic athletes and rowers with non-rowers. SETTING--The British Olympic Medical Centre, Northwick Park Hospital. PATIENTS--46 Elite female athletes comprising 19 rowers, 18 runners, and nine dancers, of whom 25 were amenorrhoeic and 21 eumenorrhoeic. MAIN OUTCOME MEASURE--Trabecular bone mineral density of the lumbar spine measured by computed tomography. RESULTS--Mean trabecular bone mineral density was 42 mg/cm3 (95% confidence interval 22 to 62 mg/cm3) lower in the amenorrhoeic than the eumenorrhoeic athletes; this difference was highly significant (p = 0.0002). Mean trabecular bone mineral density was 21 mg/cm3 (1 to 41 mg/cm3) lower in the non-rowers than the rowers; this was also significant (p = 0.05). There was no interaction between these two effects (p = 0.28). CONCLUSION--The effect of intensive exercise on the lumbar spine partially compensates for the adverse effect of amenorrhoea on spinal trabecular bone density. Images p516-a PMID:2207417

    Elite athletes undergo heavy training programs throughout the year. The aim of the present study was to evaluate blood biomarkers of redox status, oxidative stress, inflammation and angiogenesis over the course of a competitive season in elite female water polo players. The biomarkers were evaluated in four distinct phases of an athletic season. It was found that the reduced glutathione (GSH) concentration was significantly increased, whereas catalase activity was decreased in erythrocytes in phases 3 and 4 compared to phase 2. Plasma concentration of thiobarbituric acid reactive substances (TBARS) was increased in phases 3 and 4 compared to phases 1 and 2, the concentration of protein carbonyls was increased in phase 4, and total antioxidant capacity (TAC) was decreased in phases 2 and 3. Plasma monocyte chemoattractant protein-1 (MCP-1) was decreased in phases 3 and 4; interleukin-10 (IL-10) was increased in phase 4, whereas no change was observed for adiponectin and endoglin. The findings of this study indicate that oxidative stress and inflammation varies over the season in elite female water polo athletes and this information might be used to apply remedies for optimizing athletic performance and accelerating training recovery.

    In May 2011, more than a decade after the International Association of Athletics Federations (IAAF) and the International Olympic Committee (IOC) abandoned sex testing, they devised new policies in response to the IAAF's treatment of Caster Semenya, the South African runner whose sex was challenged because of her spectacular win and powerful physique that fueled an international frenzy questioning her sex and legitimacy to compete as female. These policies claim that atypically high levels of endogenous testosterone in women (caused by various medical conditions) create an unfair advantage and must be regulated. Against the backdrop of Semenya's case and the scientific and historical complexity of "gender verification" in elite sports, we question the new policies on three grounds: (1) the underlying scientific assumptions; (2) the policymaking process; and (3) the potential to achieve fairness for female athletes. We find the policies in each of these domains significantly flawed and therefore argue they should be withdrawn.

    Despite the severity and prevalence of iron deficiency in exercising women, few published reports have explored how iron deficiency interacts with another prevalent and severe condition in exercising women: the 'female athlete triad.' This review aims to describe how iron deficiency may interact with each component of the female athlete triad, that is, energy status, reproductive function, and bone health. The effects of iron deficiency on energy status are discussed in regards to thyroid function, metabolic fuel availability, eating behaviors, and energy expenditure. The interactions between iron deficiency and reproductive function are explored by discussing the potentially impaired fertility and hyperprolactinemia due to iron deficiency and the alterations in iron metabolism due to menstrual blood loss and estrogen exposure. The interaction of iron deficiency with bone health may occur via dysregulation of the growth hormone/insulin-like growth factor-1 axis, hypoxia, and hypothyroidism. Based on these discussions, several future directions for research are presented.

    Two elite female athletes presented with anterior knee pain with range of motion and reproducible tenderness to palpation. Diagnostic arthroscopy was performed in both cases resulting in excision of a nodular pigmented villonodular synovitis (PVNS) in the first patient and scar tissue in the second patient. Correct diagnosis of anterior knee pain in the elite female athlete can present a challenge to clinicians. Although patellofe-moral pain is the most common diagnosis, other uncommon causes include PVNS and residual scar formation in patients with a history of surgery or trauma. Magnetic resonance imaging (MRI) images are helpful in confirming the diagnosis, however, in a subset of patients, the physician must rely on clinical suspicion and physical exam to make the proper diagnosis. Given the possibility of a false negative MRI images, patients with persistent anterior knee pain with a history of knee surgeries and focal tenderness reproducible on physical exam may benefit from a diagnostic arthroscopy.

    2013-01-01

    Iron is an essential micronutrient involved in oxidative metabolism and critical to exercise performance. The prevalence of iron deficiency (ID) is much higher in active women for a variety of reasons, and poor iron status has been shown to be detrimental to overall health as well as physical performance. Iron status can be assessed using a number of indicators; however clinical cut-offs for active populations remain controversial. Randomized, placebo-controlled supplementation trials of iron-depleted female athletes have shown that oral iron supplementation in doses of 100-mg FeSO4·d (approximately 20 mg elemental iron) improves iron status and may improve measures of physical performance. It is recommended that female athletes most at risk of ID be screened at the beginning of and during the training season using hemoglobin and serum ferritin, and appropriate dietary and/or supplementation recommendations be made to those with compromised iron status.

    Adolescence and emerging adulthood are critical windows for establishing life-long behaviors. We assessed long-term outcomes of a prospective randomized harm reduction/health promotion program for female high school athletes. The intervention's immediate beneficial effects on diet pill use and unhealthy eating behaviors have been reported; however, tobacco, alcohol and marijuana use were not immediately altered (Elliot et al, 2004). One to three years following graduation, positive benefits in those domains became evident, and intervention students reported significantly less lifetime use of cigarettes, marijuana, and alcohol. Sport teams may be effective vehicles for gender-specific interventions to promote competency skills and deter harmful actions, and those benefits may manifest when acquired abilities are applied in new environments following high school graduation.

    Background: Vertical jump is an index representing leg/kick power. The explosive movement of the kick is the key to scoring in martial arts competitions. It is important to determine factors that influence the vertical jump to help athletes improve their leg power. The objective of the present study is to identify anthropometric factors that influence vertical jump height for male and female martial arts athletes. Methods: Twenty-nine male and 25 female athletes participated in this study. Participants were Malaysian undergraduate students whose ages ranged from 18 to 24 years old. Their heights were measured using a stadiometer. The subjects were weighted using digital scale. Body mass index was calculated by kg/m2. Waist–hip ratio was measured from the ratio of waist to hip circumferences. Body fat % was obtained from the sum of four skinfold thickness using Harpenden callipers. The highest vertical jump from a stationary standing position was recorded. The maximum grip was recorded using a dynamometer. For standing back strength, the maximum pull upwards using a handle bar was recorded. Multiple linear regression was used to obtain the relationship between vertical jump height and explanatory variables with gender effect. Results: Body fat % has a significant negative relationship with vertical jump height (P < 0.001). The effect of gender is significant (P < 0.001): on average, males jumped 26% higher than females did. Conclusion: Vertical jump height of martial arts athletes can be predicted by body fat %. The vertical jump for male is higher than for their female counterparts. Reducing body fat by proper dietary planning will help to improve leg power. PMID:23785254

    Low or reduced energy availability (LEA) is linked to functional hypothalamic oligomenorrhea/amenorrhea (FHA), which is frequently reported in weight-sensitive sports. This makes LEA a major nutritional concern for female athletes. The aim of this study was to describe dietary characteristics of athletes with LEA and/or FHA. Endurance athletes (n = 45) were recruited from national teams and competitive clubs. Protocols included gynecological examination, body composition, eating disorder evaluation, and 7-day dietary intake and EA assessment. Athletes with disordered eating behavior/eating disorders (n = 11), menstrual dysfunction other than FHA (n = 5), and low dietary record validity (n = 4) were excluded. Remaining subjects (n = 25) were characterized by EA [optimal: ≥ 45 kcal (188 kJ)/kg fat-free mass (FFM)/day (n = 11), LEA: < 45 kcal (188 kJ)/kg FFM/day (n = 14)] and reproductive function [eumenorrhea (EUM; n = 10), FHA (n = 15)]. There was no difference in EA between FHA and EUM subjects. However, FHA and LEA subjects shared the same dietary characteristics of lower energy density (ED) [(P = 0.012; P = 0.020), respectively], and fat content [(P = 0.047; P = 0.027), respectively]. Furthermore, FHA subjects had a lower intake of carbohydrate-rich foods (P = 0.019), higher fiber content (P < 0.001), and drive for thinness score (P = 0.003). Conclusively, low ED together with high fiber content may constitute targets for dietary intervention in order to prevent and treat LEA and FHA in female athletes.

    Few published studies of left ventricular (LV) mass in female endurance athletes have been performed with M-mode echocardiography, which involves assumptions of LV geometry. Therefore, magnetic resonance imaging, a 3-dimensional technique, was used to examine LV mass, LV end-diastolic volume and mean wall thickness in female long distance runners (n = 13; mean age 29 years), cyclists (n = 12; mean age 26 years) and cross-country skiers (n = 11; mean age 24 years), and the findings were compared with sedentary control subjects (n = 10; mean age 27 years) matched for height and body weight. The physical characteristics for all subjects included height (mean 166 cm, and body weight (mean 56 kg). The percent body fat (mean 11.7) and maximal oxygen uptake (VO2max, mean 63 ml.kg-1.min-1) were similar (p greater than 0.05) among all athletic groups, but significantly different from the control group (body fat, mean 22.5%; VO2max, mean 35 ml.kg-1.min-1). LV mass (mean 159 kg), LV end-diastolic volume (mean 122 ml), and mean wall thickness (mean 11.5 mm) were also similar among the athletic groups and significantly larger than the following control values: LV mass (mean 115 g), LV end-diastolic volume (mean 93 ml) and mean wall thickness (mean 9.8 mm). Ratios of LV mass to lean body weight were similar among all athletic groups, although athletic groups had larger ratios (p less than 0.05) than the sedentary control subjects. LV mass/LV end-diastolic volume ratio was similar (p greater than 0.05) among all groups.(ABSTRACT TRUNCATED AT 250 WORDS).

    Female athletes experience pressure to conform to social and sporting norms concerning body weight. This study compared general and sporting body dissatisfaction and disordered eating symptomatology among 320 elite, recreational, and noncompetitive female athletes aged 17 to 30 years competing in leanness focused sports and nonleanness focused sports. Participants completed an online questionnaire including demographic questions, the Eating Attitudes Test, and the Figure Rating Scale. Athletes from leanness focused sports reported higher levels of body dissatisfaction and greater disordered eating symptomatology regardless of participation level. Elite athletes reported higher levels of body dissatisfaction and greater disordered eating symptomatology regardless of sport type, and differences between recreational and noncompetitive athletes were not found. More than 60% of elite athletes from leanness focused and nonleanness focused sports reported pressure from coaches concerning body shape. The findings have important implications for identifying risk factors for eating disorders among female athletes, where athletes who compete at elite level and those who compete in leanness focused sports at any level may be at higher risk for developing eating disorders.

  17. Anabolic-androgenic steroid use among young male and female athletes: is the game to blame?

    PubMed

    Harmer, P A

    2010-01-01

    The use of anabolic-androgenic steroids (AAS) by young athletes has been a primary concern of sports governing bodies because of the implications for unfair advantage in performance and the potential for adverse side effects. Research over several decades indicated a lifetime prevalence of AAS use for adolescent males of 4-6% and for females of 1.5-3%, indicating a problem involving millions of athletes and a potential epidemic of AAS-related pathologies. However, recent studies have questioned the presumption that participation in organised sport is the primary risk factor for AAS use in adolescents as well as the extant estimates of the magnitude of the problem. Increasing evidence indicates that AAS use is associated with non-athletes and is linked to a broader syndrome of problem behaviours rather than efforts to achieve sporting success, and that sports participation may be protective against AAS use. Moreover, employing lifetime prevalence to gauge AAS use limits accurate evaluation of the personal and public health risk as the majority of respondents are not habitual users. Previous studies may have also inflated prevalence values through ambiguously worded survey questions and other design flaws, and few data are available on actual dosages. Prevention efforts need to be focused beyond organised sport and target the general adolescent population rather than athletes and should be founded on interventions with demonstrated efficacy for delinquent, antisocial and self-destructive behaviours rather than the ethical imperative of fair play.

    Iron deficiency anemia is the most prevalent micronutrient deficiency in the world, affecting 20-50% of the world's population. It is estimated that 10 and 20% of male and female athletes are iron deficient, respectively. Iron deficiency has deleterious effects on the physical performance of athletes. It decreases aerobic capacity, increases heart rate and elongates the recovery time after exercise. In this cross-sectional study, 42 semi-professional female athletes who had been playing in basketball, volleyball and handball super league teams served as subjects. Data on socioeconomic and fertility status as well as the type of sport were obtained through a questionnaire. Nutritional data were gathered with a 3 day dietary recall. Total intake of calorie, iron, zinc, folate, vitamin C and B12 were also analyzed. In addition, ferritin and TIBC were measured and a CBC test was done for each subject. The results showed that the mean total calorie intake of women was 2049.79 +/- 735.12 kcal, where their iron intake was 22.33 +/- 9.24 mg day(-1). There was a significant difference between the iron intake of basketball and volleyball players (p = 0.036). Of our subjects, 33.33% had low ferritin levels (< 30 ng mL(-1)) and it was lowest in handball players. Higher than normal ferritin levels were seen in 12.5% of the subjects. We saw a significant difference in ferritin levels of basketball and handball players (p = 0.047). We conclude that the intake of calorie and iron is low in female athletes and therefore, their hematological indices such as ferritin level are below standard values.

    Purpose The aim of this study was to determine the effect of Ramadan fasting on body composition, calorie intake and physical performance in young female athletes undertaking training sessions during Ramadan. Methods Twelve voluntary female athletes (15-27 years old) were assigned to the research. A prospective study was conducted to investigate the athletes on four different occasions: one week before Ramadan (T1), the second (T2) and fourth (T3) weeks of Ramadan, and two weeks after the end of Ramadan (T4). Food intake, body composition and physical performance (agility, balance and explosive leg power) were investigated on each occasion. Further, Physical performance was assessed by agility, vertical jump and balance tests. Results There was a significant main effect for time for body composition indices. A significant decrease was observed in weight (P=0.01) and body mass index (BMI) (P=0.01) in T2 compared with T1, further decrease in weight (P<0.001) and BMI (P<0.001) was observed in T3 compared to T1. Calorie intake decreased significantly in T3 compared with T1 (P=0.008), and increased significantly in T4 compared with T3 (P=0.04). There was a significant main effect for time for agility performance (P=0.03), but no significant main effect for time was observed for vertical jumping (P=0.1) and balance performance (P=0.3). Conclusions This study has found that Ramadan fasting could affect the body composition, but not physical performance in female athletes during Ramadan. PMID:22375235

    The purpose of this study was to examine physiologic performance test differences by competition level (high school and Division-I collegiate athletes) and player position (hitter, setter, defensive specialist) in 4 volleyball-related tests. A secondary purpose was to establish whether a 150-yd shuttle could be used as a field test to assess anaerobic capacity. Female participants from 4 varsity high school volleyball teams (n = 27) and 2 Division-I collegiate volleyball teams (n = 26) were recruited for the study. Participants completed 4 performance-based field tests (vertical jump, agility T-test, and 150- and 300-yd shuttle runs) after completing a standardized dynamic warm-up. A 2-way multivariate analysis of variance with Bonferroni post hoc adjustments (when appropriate) and effect sizes were used for the analyses. The most important findings of this study were that (a) college volleyball athletes were older, heavier, and taller than high school athletes; (b) high school athletes had performance deficiencies in vertical jump/lower-body power, agility, and anaerobic fitness; (c) lower-body power was the only statistically significant difference in the performance test measures by player position; and (d) the correlation between the 150- and 300-yd shuttle was moderate (r = 0.488). Female high school volleyball players may enhance their ability to play collegiate volleyball by improving their vertical jump, lower-body power, agility, and anaerobic fitness. Furthermore, all player positions should emphasize lower-body power conditioning. These physical test scores provide baseline performance scores that should help strength and conditioning coaches create programs that will address deficits in female volleyball player performance, especially as they transition from high school to college.

    Hyperactivity of the Hypthalamus-Pituitary-Adrenal (HPA)-axis is common in major depression and evident from e.g., a frequently exaggerated response to combined application of dexamethasone and CRH in this disorder. HPA-axis activity and hence the secretion of glucocorticoids (GC), the endpoint of the HPA-axis, depends to some extent on GC binding to glucocorticoid receptors (GR) that are abundantly expressed in the hippocampus. To assess whether differences in hippocampal GR expression occur in association with depression, we investigated GR-alpha protein immunoreactivity (ir) in postmortem hippocampal tissue of an elderly cohort of 9 well-characterized depressed patients and 9 control subjects that were pair-wise matched for age, sex, CSF-pH and postmortem delay. Abundant nuclear GR-ir was observed in neurons of the hippocampal Ammon's horn (CA) and dentate gyrus (DG) subregions. GR-ir in the DG correlated positively with age in the depressed but not the control group. Although no significant differences were found in GR-ir between the depressed and control groups, a significant increase in GR-ir was present in depressed females compared to depressed males. Whether this sex difference in hippocampal GR-ir in depression relates to the increased incidence of depression in females awaits further study.

    We investigated heavy training- and overtraining-induced changes in heart rate and blood pressure variability during supine rest and in response to head-up tilt in female endurance athletes. Nine young female experimental athletes (ETG) increased their training volume at the intensity of 70-90% of maximal oxygen uptake (VO2max) by 125% and training volume at the intensity of < 70% of VO2max by 100% during 6-9 weeks. The corresponding increases in 6 female control athletes were 5% and 10%. The VO2max of the ETG and the control athletes did not change, but it decreased from 53.0 +/- 2.2 ml x kg(-1) x min(-1) to 50.2 +/- 2.3 ml x kg(-1) x min(-1) (mean+/-SEM, p < 0.01) in five overtrained experimental athletes. In the ETG, low-frequency power of R-R interval (RRI) variability during supine rest increased from 6 +/- 1 ms2 x 10(2) to 9 +/- 2 ms2 x 10(2) (p < 0.05). The 30/15 index (= RRI(max 30)/RRI(min 15), where RRI(max 30) denotes the longest RRI close to the 30th RRI and RRI(min 15) denotes the shortest RRI close to the 15th RRI after assuming upright position in the head-up tilt test), decreased as a result of training (analysis of variance, p = 0.05). In the ETG, changes in VO2max were related to the changes in total power of RRI variability during standing (r = 0.74, p < 0.05). Heart rate response to prolonged standing after head-up tilt was either accentuated or attenuated in the overtrained athletes as compared to the normal training state. We conclude that heavy training could increase cardiac sympathetic modulation during supine rest and attenuated biphasic baroreflex-mediated response appearing just after shifting to an upright position. Heavy-training-/overtraining-induced decrease in maximal aerobic power was related to decreased heart rate variability during standing. Physiological responses to overtraining were individual.

    Little data exist for upper and lower body mechanical power capability of adolescent athletes. This study compared arm (A) and leg (L) anaerobic peak and mean power (PP and MP) of 20 male and 20 female adolescent athletes after normalization for body mass (BM), fat-free mass (FFM), and lean A and L cross-sectional area (CSA). Power outputs were assessed by the Wingate anaerobic test. FFM and CSA were estimated via anthropometry. No significant (P > 0.05) differences existed between the sexes in Tanner sexual maturity, chronological age, or overall training activity. Males had higher (P < 0.001) absolute PP (W) (L 694 vs 442; A 494 vs 309) and MP (L 548 vs 307; A 337 vs 214). Ratio normalization and ANCOVA were used to remove the influence of body size differences. Ratio normalization showed that males had greater leg PP/BM, MP/BM, MP/FFM, MP/CSA, as well as arm PP/BM and MP/BM, whereas all leg and arm PP and MP ANCOVA adjusted means for BM, FFM, and CSA, except arm MP adjusted for FFM, were significantly (P < 0.01) higher for males than females. We conclude that factors other than muscle mass, possibly qualitative in nature, are responsible for the sex difference in anaerobic performance of adolescent athletes.

    This study evaluates the relationship between body iron losses and gains in artistic gymnastics female athletes. It shows that despite the low iron intake and exercise-induced hemolysis, iron deficiency or iron-deficiency anemia does not occur, but partial changes in the hematological profile do. The hypothesis that gymnasts' nutritional behavior contributes to anemia, which may be aggravated by exercise-induced hemolysis, led to this cross-sectional study, conducted with 43 female artistic gymnasts 6-16 yr old. The control group was formed by 40 nontraining girls, paired by age. Hemogram, serum iron, ferritin, soluble transferrin receptor, haptoglobin, total and fractional bilirubin, Type I urine, and parasitologic and occult fecal blood tests were evaluated. The athletes presented mean hematimetric and serum iron values (p = .020) higher than those of the control group. The bilirubin result discarded any hemolytic alteration in both groups. The haptoglobin results were lower in the athlete group (p = .002), confirming the incidence of exercise-induced hemolysis. Both groups presented low iron intake. The results suggest that artistic gymnastics practice leads to exercise-induced hemolysis and partially changes the hematological profile, although not causing iron deficiency or iron-deficiency anemia, even in the presence of low iron intake.

  5. Current perspectives on the etiology and manifestation of the "silent" component of the Female Athlete Triad.

    The Female Athlete Triad (Triad) represents a syndrome of three interrelated conditions that originate from chronically inadequate energy intake to compensate for energy expenditure; this environment results in insufficient stored energy to maintain physiological processes, a condition known as low energy availability. The physiological adaptations associated with low energy availability, in turn, contribute to menstrual cycle disturbances. The downstream effects of both low energy availability and suppressed estrogen concentrations synergistically impair bone health, leading to low bone mineral density, compromised bone structure and microarchitecture, and ultimately, a decrease in bone strength. Unlike the other components of the Triad, poor bone health often does not have overt symptoms, and therefore develops silently, unbeknownst to the athlete. Compromised bone health among female athletes increases the risk of fracture throughout the lifespan, highlighting the long-term health consequences of the Triad. The purpose of this review is to examine the current state of Triad research related to the third component of the Triad, ie, poor bone health, in an effort to summarize what we know, what we are learning, and what remains unknown.

    Contemporary nutrition guidelines promote a variety of periodized and time-sensitive recommendations, but current information regarding the knowledge and practice of these strategies among world-class athletes is limited. The aim of this study was to investigate this theme by implementing a questionnaire on dietary periodization practices in national/international level female (n=27) and male (n=21) middle- and long-distance runners/race-walkers. The questionnaire aimed to gain information on between and within-day dietary choices, as well as timing of pre- and post-training meals and practices of training with low or high carbohydrate (CHO) availability. Data are shown as percentage (%) of all athletes, with differences in responses between sub-groups (sex or event) shown as Chi-square x(2) when p<0.05. Nearly two-thirds of all athletes reported that they aim to eat more food on, or after, hard training days. Most athletes said they focus on adequate fueling (96%) and adequate CHO and protein (PRO) recovery (87%) around key sessions. Twenty-six percent of athletes (11% of middle vs 42% of long-distance athletes [x(2) (1, n=46) = 4.308, p=0.038, phi=0.3])) reported to undertake training in the fasted state, while 11% said they periodically restrict CHO intake, with 30% ingesting CHO during training sessions. Our findings show that elite endurance athletes appear to execute pre- and post-key session nutrition recovery recommendations. However, very few athletes deliberately undertake some contemporary dietary periodization approaches, such as training in the fasted state or periodically restricting CHO intake. This study suggests mismatches between athlete practice and current and developing sports nutrition guidelines.

    We evaluated the effects of regular physical exercise on anemia and iron status in young non-professional female athletes. A total of 191 healthy white Italian women (23.5 +/- 4.68 years) were analyzed; 70 were non-professional athletes performing 11.1 +/- 2.63 h week(-1) exercise and 121 were sedentary controls. Blood markers of anemia and iron status-hemoglobin (Hb), hematocrit (Hct), red blood cells (RBC), serum ferritin, iron, transferrin (Tf), transferrin saturation (TfS), soluble transferrin receptor (sTfR), and the sTfR/log ferritin ratio (sTfR-F index)-were evaluated. Anemia threshold was Hb < 120 g l(-1). Ferritin concentrations < 12 microg l(-1) were considered as iron deficiency (ID). Frequency of anemia (15.7 versus 10.7%, P = 0.32), ID (27.1 versus 29.8%, P = 0.70), and ID anemia (8.6 versus 5.8%, P = 0.46) was not different in athletes and controls. However, athletes were threefold more likely than controls (17.1 versus 5.8%) to have serum iron < 50 microg dl(-1) [odds ratio (OR) 3.37, P = 0.012]. Low-TfS (<15%) was found in 25.7% of athletes and in 13.2% of controls, OR 2.27, P = 0.030. Elevated-sTfR (>1.76 mg l(-1)) was found in 24.3% of athletes and in 12.4% of controls, OR 2.27, P = 0.034. Regular non-professional sport activity does not cause an increased rate of anemia or of iron deficiency in fertile women. However, physical exercise has an impact on iron status as it reduces serum iron and transferrin saturation, and elevates sTfR. Nearly one fifth of recreational athletes have anemia and a third have iron deficit, these conditions can decrease their physical performance.

    Controlling dynamic interactions between the lower limb and ground is important for skilled locomotion and may influence injury risk in athletes. It is well known that female athletes sustain anterior cruciate ligament (ACL) tears at higher rates than male athletes, and exhibit lower extremity biomechanics thought to increase injury risk during sport maneuvers. The purpose of this study was to examine whether lower extremity dexterity (LED)--the ability to dynamically control endpoint force magnitude and direction as quantified by compressing an unstable spring with the lower limb at submaximal forces--is a potential contributing factor to the "at-risk" movement behavior exhibited by female athletes. We tested this hypothesis by comparing LED-test performance and single-limb drop jump biomechanics between 14 female and 14 male high school soccer players. We found that female athletes exhibited reduced LED-test performance (p=0.001) and higher limb stiffness during landing (p=0.008) calculated on average within 51 ms of foot contact. Females also exhibited higher coactivation at the ankle (p=0.001) and knee (p=0.02) before landing. No sex differences in sagittal plane joint angles and center of mass velocity at foot contact were observed. Collectively, our results raise the possibility that the higher leg stiffness observed in females during landing is an anticipatory behavior due in part to reduced lower extremity dexterity. The reduced lower extremity dexterity and compensatory stiffening strategy may contribute to the heightened risk of ACL injury in this population.

    We investigated the iron-related haematological parameters in both male and female athletes participating in different sporting disciplines necessitating different metabolic energy demands. A total of 873 athletes (514 males, mean age: 22.08 ± 4.95 years and 359 females, mean age: 21.38 ± 3.88 years) were divided according to gender and to the predominant energy system required for participation in sport (aerobic, anaerobic or mixed) and haematological and iron-related parameters were measured. For both male and female athletes, significant differences related to the predominant energy system were found at a general level: male (Wilks' λ = 0.798, F = 3.047, p < 0.001) and female (Wilks' λ = 0.762, F = 2.591, p < 0.001). According to the ferritin cutoff value of 35 μg/L, whole body iron and sTfR significantly differed in all three groups of male and female athletes (p < 0.001). The percentage of hypochromic erythrocytes in male athletes was significantly higher only in those who required an anaerobic energy source (p < 0.001), whilst in the females hypochromic erythrocytes (p < 0.001) and haemoglobin (anaerobic, p = 0.042; mixed, p = 0.006) were significantly different only in anaerobic and mixed energy source athletes. According to the ferritin cutoff value of 22 μg/L, in females, whole body iron, sTfR and hypochromic erythrocytes were significantly higher in all three groups of athletes than those below the aforementioned cutoff value (p < 0.001). We conclude that the predominant energy system required for participation in sport affects haematological parameters. sTfR and body iron proved to be reliable parameters for monitoring the dynamics of iron metabolism and could contribute to successful iron-deficiency prevention.

    Introduction Exercise training, besides many health benefits, may result in cardiac remodelling which is dependent on the type and amount of exercise performed. It is not clear, however, whether significant adaptation in cardiac structure is possible in females undergoing resistance type of exercise training. Rigorous high volume training of most muscle groups emphasising resistance exercises are being undertaken by athletes of some aesthetic sports such as female fitness (light bodybuilding). The impact of this type of training on cardiac adaptation has not been investigated until now. The aim of the current study was to disclose the effect of high volume resistance training on cardiac structure and function. Methods 11 top-level female fitness athletes and 20 sedentary age-matched controls were recruited to undergo two-dimensional echocardiography. Results Cardiac structure did not differ between elite female fitness athletes and controls (p > 0.05), and fitness athletes had a tendency for a smaller (p = 0.07) left ventricular (LV) mass indexed to lean body mass. Doppler diastolic function index (E/A ratio) and LV ejection fraction were similar between the groups (p > 0.05). Conclusions Elite female fitness athletes have normal cardiac size and function that do not differ from matched sedentary controls. Consequently, as high volume resistance training has no easily observable effect on adaptation of cardiac structure, when cardiac hypertrophy is present in young resistance-trained lean female, other reasons such as inherited cardiac disease are to be considered carefully.

    Dermoid cysts rarely present as mesenteric cysts. Mesenteric cysts are rare pathologic entities, with a reported incidence of approximately 1 of 27 000 to 1 of 100 000 admissions. Mesenteric cyst was first described by Florentine anatomist Benevieni in 1507, while performing an autopsy on an eight-year-old boy. Most commonly, teratoma occurs in the early age group. Mature mesenteric teratoma in adulthood is extremely rare. Teratoma are germ cell tumours commonly composed of multiple cell types derived from one or more of the 3 germ layers. We present the case of a 69-year-old elderly female who presented with abdomen pain for nine months with right lumbar and right iliac fossa mass. Computed Tomography (CT) abdomen revealed bilocular cystic lesion with possibility of mucinous cystadenoma with no definitive organ of origin. She underwent explorative laparotomy and total excision of the cystic mass. Histopathologic examination confirmed diagnosis of mature cystic teratoma of mesentery. This case report highlights the need to maintain high index of suspicion while evaluating abdominal mass. PMID:28274002

    Resistance exercise (RE) preceding the provision of high-quality dairy protein supports muscle anabolism. Milk contains bioactive components, including two high-quality protein fractions, calcium and vitamin D, each of which has been shown modulate body composition (increasing lean mass and decreasing fat mass) under energy balance and hypoenergetic conditions. These dairy nutrients are also essential for skeletal health. Acutely, no study of RE and milk/whey consumption has been undertaken exclusively in female athletes, let alone women, nevertheless, studies with both men and women show increased lean mass accretion following milk/whey compared to soy/placebo. Currently, no longer-term RE studies with milk supplementation have been done in female athletes. However, trials in young recreationally active women demonstrated augmented increases in lean mass and decreases in fat mass with RE and milk or whey protein consumption. The amount of protein consumed post-exercise is also important; two trials using yogurt (5 g protein/6 oz) failed to demonstrate a positive change in body composition compared to placebo. For bone health, RE plus dairy improved bone mineral density at clinically important sites and reduced bone resorption. With energy restriction, in one study, higher dairy plus higher protein resulted in greater fat loss, lean mass gain and improved bone health in overweight women. In another study, milk and calcium supplementation showed no greater benefit. Neither trial exclusively utilized RE. Overall, RE and milk/dairy consumption positively impact body composition in women by promoting losses in fat, gains or maintenance of lean mass and preservation of bone. Future studies in female athletes and under energy restriction with RE alone are warranted.

    The purpose was to investigate perceived stress and recovery related to cycling performance of female athletes over one full year. 20 female athletes (age, 27±8 years; ˙VO2max, 50.3±4.6 mL·kg(-1)·min(-1)) were measured 8 times in one year to determine perceived stress and recovery (RESTQ-Sport) in relation to cycling performance (Lamberts and Lambert Submaximal Cycle Test (LSCT)). All 19 RESTQ-Sport scales were calculated and scores of the 4 main categories were determined (i. e., general stress, general recovery, sport-specific stress and sport-specific recovery). A balance score of total stress and recovery was calculated by recovery-stress. Power at the second stage (P80), third stage (P90) and heart rate recovery (HRR60 s) of the LSCT were determined as performance parameters. 110 RESTQ-Sports and LSCTs were analysed using a multilevel approach (random intercepts model). Higher self-efficacy was related to improvement of all performance parameters. Higher total recovery stress, and lower emotional stress were related to improvement of P90 and HRR60 s. Higher sport-specific recovery was related to P80, higher general stress, fatigue and physical complaints were related to decreased P90 and higher social stress and injury were related to decreased HRR60 s. Improved perceived recovery and stress contributed to an improved performance. Relevant information could be provided by monitoring changes in perceived stress and recovery of female athletes.

    The purpose of this investigation was to determine the agreement between multifrequency bioelectrical impedance analysis (BIA) and dual-energy x-ray absorptiometry (DXA) for measuring body fat percentage (BF%), fat-free mass (FFM), and total body and segmental lean soft tissue (LST) in collegiate female athletes. Forty-five female athletes (age = 21.2 ± 2.0 years, height = 166.1 ± 7.1 cm, weight = 62.6 ± 9.9 kg) participated in this study. Variables measured through BIA and DXA were as follows: BF%, FFM, and LST of the arms (ARMS(LST)), the legs (LEGS(LST)), the trunk (TRUNK(LST)), and the total body (TOTAL(LST)). Compared with the DXA, the InBody 720 provided significantly lower values for BF% (-3.3%, p < 0.001) and significantly higher values for FFM (2.1 kg, p < 0.001) with limits of agreement (1.96 SD of the mean difference) of ±5.6% for BF% and ±3.7 kg for FFM. No significant differences (p < 0.008) existed between the 2 devices (InBody 720-DXA) for ARMS(LST) (0.05 kg), TRUNK(LST) (0.14 kg), LEGS(LST) (-0.4 kg), and TOTAL(LST) (-0.21 kg). The limits of agreement were ±0.79 kg for ARMS(LST), ±2.62 kg for LEGS(LST), ±3.18 kg for TRUNK(LST), and ±4.23 kg for TOTAL(LST). This study found discrepancies in BF% and FFM between the 2 devices. However, the InBody 720 and DXA appeared to provide excellent agreement for measuring total body and segmental LST. Therefore, the InBody 720 may be a rapid noninvasive method to assess LST in female athletes when DXA is not available.

    Context: Deficits in lower limb kinematics and postural stability are predisposing factors to the development of knee ligamentous injury. The extent to which these deficits are present after anterior cruciate ligament (ACL) reconstruction is still largely unknown. The primary hypothesis of the present study was that female athletes who have undergone ACL reconstruction and who have returned to sport participation would exhibit deficits in dynamic postural stability as well as deficiencies in hip- and knee-joint kinematics when compared with an age-, activity-, and sex-matched uninjured control group. Objective: To investigate dynamic postural stability as quantified by the Star Excursion Balance Test (SEBT) and simultaneous hip- and knee-joint kinematic profiles in female athletes who have undergone ACL reconstruction. Design: Descriptive laboratory study. Setting: University motion-analysis laboratory. Patients or Other Participants: Fourteen female athletes who had previously undergone ACL reconstruction (ACL-R) and 17 age- and sex-matched uninjured controls. Intervention(s): Each participant performed 3 trials of the anterior, posterior-medial, and posterior-lateral directional components of the SEBT. Main Outcome Measure(s): Reach distances for each directional component were quantified and expressed as a percentage of leg length. Simultaneous hip- and knee-joint kinematic profiles were recorded using a motion-analysis system. Results: The ACL-R group had decreased reach distances on the posterior-medial (P < .01) and posterior-lateral (P < .01) directional components of the SEBT. During performance of the directional components of the SEBT, ACL-R participants demonstrated altered hip-joint frontal-, sagittal-, and transverse-plane kinematic profiles (P < .05), as well as altered knee-joint sagittal-plane kinematic profiles (P < .05). Conclusions: Deficits in dynamic postural stability and concomitant altered hip- and knee-joint kinematics are present after ACL

    Background The aim of this study was to evaluate the influence of three months of dietary intervention on menstrual cycle in young female athletes with amenorrhea or oligomenorrhea. Methods From forty-five female professional athletes with menstrual irregularity that were recruited thirty-one, aged 18.1 ± 2.6 years, completed the study and were analyzed. Hyperprolactinemia, thyroid dysfunction, primary ovarian failure and hyperandrogenism were excluded in the study participants. The subjects started intense training at the age of 11.2 ± 3.5 years and continued during next 6.8 ± 3.3 years. Energy and nutrients intake, total energy expenditure, energy availability and body composition as well as serum concentrations of LH, FSH, 17 – beta estradiol and progesterone were measured at the beginning of the study and after three months of individualized dietary intervention. Results Following three months of dietary intervention significant increase in energy intake (2354 ± 539 vs. 258 8 ± 557 kcal, P = 0.004) and energy availability (28.3 ± 9.2 vs. 35.8 ± 12.3 kcal/kg FFM/d, P = 0.011) was observed as well as improved energy balance (−288 ± 477 vs. -51 ± 224 kcal/d, P = 0.002). Though no changes in BMI and body composition were noted but significant rise in LH concentrations (3.04 ± 1.63 vs. 4.59 ± 2.53 mIU/ml, P = 0.009) and LH to FSH ratio (0.84 ± 0.56 vs. 0.96 ± 0.52, P = 0.001) was achieved, but no restoration of menstrual cyclicity. Conclusions This report provides further support for the role of energy deficiency in menstrual disorders among young female athletes and the benefits of an adequate energy intake and energy availability on hormones concentration. Continuation controlled dietary intervention is needed to assess the extent to which long-term improvement in the nutritional status results in improvements in the hormonal status of female athletes, to an extent that

    Few studies have examined sex differences in body perceptions in sports where the pressure to display a certain physique is reduced. The aim of the present study was to investigate sex differences in physical self-perceptions and body image in junior athletes who are involved in sprint kayaking, a sport where a low body weight is relatively unimportant. 12 male and 13 female members (aged 13-17 yr.) of the British Canoe Union Junior Development Squad for sprint-kayak racing completed the Physical Self-perception Profile for Children and the Multidimensional Body-Self Relations Questionnaire. Multivariate analysis of variance indicated that girls reported significandy higher Sports Competence and lower Appearance Orientation scores than boys. This study has raised a number of issues surrounding the physical self-perceptions and body image of junior athletes involved in a power- and strength-based sport. It seems that male athletes may also experience pressures to conform to a male version of a 'beautiful body'.

    The purpose of the study was to evaluate marked postural asymmetry and gross joint mobility in elite female volleyball athletes. Sixty-two Czech and Slovak elite female volleyball athletes (age 20.7±2.03 years, body mass 71.1±6.18 kg, body height 1.804±.0618 m, BMI 21.8±1.78) were examined by an experienced rehabilitation physician. The set of tests included the frontal posture gross examination, the forward bending test from the standing position and the deep squat test. The spiking hand and the presence of any lower extremity injury were estimated by interview. The proportion test, Mann-Whitney test and t-test were used to evaluate statistical significance (p<0.05). Fifty subjects (80.6%) exhibited "typical" frontal plane posture in which the acromion, scapula and the iliac crest were in a higher position on the left side than on the right, significantly more frequently than all the other patterns (proportion test, p<0.0001). Ninety-eight percent of the subjects with the "LLL pattern" preferred the right arm for spiking (proportion test, p<0.0001). Forty-one subjects (66%) exhibited hypermobility in the forward bending test, significantly more frequently than twenty-one subjects (34%) with normal results (proportion test, p=0.0003). Thirty-four subjects (55%) did not succeed in the deep squat test and hypermobility in the forward bending test paradoxically prevailed in them significantly (proportion test, p=0.004). Restriction in the deep squat test was not linked to obesity, age (t-test, p=0.081) nor knee (proportion test, p=0.85) and ankle injury (Mann-Whitney test, p=0.36) in the past. Significant prevalence of hypermobility in the forward bending test was not surprising because of general body composition and the performance of regular stretching exercises in elite female volleyball athletes. On the other hand, surprisingly, more than half of the subjects did not succeed in the deep squat test. The cause of poor results in the deep squat test could be due

    Context: Anterior cruciate ligament (ACL) injuries are common in female athletes and are related to poor neuromuscular control. Comprehensive neuromuscular training has been shown to improve biomechanics; however, we do not know which component of neuromuscular training is most responsible for the changes. Objective: To assess the efficacy of either a 4-week core stability program or plyometric program in altering lower extremity and trunk biomechanics during a drop vertical jump (DVJ). Design: Cohort study. Setting: High school athletic fields and motion analysis laboratory. Patients or Other Participants: Twenty-three high school female athletes (age = 14.8 ± 0.8 years, height = 1.7 ± 0.07 m, mass = 57.7 ± 8.5 kg). Intervention(s): Independent variables were group (core stability, plyometric, control) and time (pretest, posttest). Participants performed 5 DVJs at pretest and posttest. Intervention participants engaged in a 4-week core stability or plyometric program. Main Outcome Measure(s): Dependent variables were 3-dimensional hip, knee, and trunk kinetics and kinematics during the landing phase of a DVJ. We calculated the group means and associated 95% confidence intervals for the first 25% of landing. Cohen d effect sizes with 95% confidence intervals were calculated for all differences. Results: We found within-group differences for lower extremity biomechanics for both intervention groups (P ≤ .05). The plyometric group decreased the knee-flexion and knee internal-rotation angles and the knee-flexion and knee-abduction moments. The core stability group decreased the knee-flexion and knee internal-rotation angles and the hip-flexion and hip internal-rotation moments. The control group decreased the knee external-rotation moment. All kinetic changes had a strong effect size (Cohen d > 0.80). Conclusions: Both programs resulted in biomechanical changes, suggesting that both types of exercises are warranted for ACL injury prevention and should be

    The purpose of the study was to assess the within-session and between-session reliability of knee kinematics and kinetics in a vertical drop jump task among elite female handball and football athletes. Specifically, we aimed to quantify the within-session waveform consistency and between-session consistency of the subject ranking for a variety of knee kinematics and kinetics. Forty-one elite female handball and football (soccer) athletes were tested in two sessions. The reliability of three-dimensional knee biomechanical measurements was quantified by the intra-class correlation, Spearman's rank correlation, and typical error. All the selected discrete variables achieved excellent within-session reliability (ICC>0.87). The typical error of valgus angles, internal rotation angles, and internal rotation moment was constant throughout the whole stance phase. For between-session reliability, the selected discrete variables achieved good to excellent reliability (ICC>0.69), except peak internal rotation moment (ICC=0.40). All between-session rank correlation coefficients ranged from 0.56 to 0.90. Most of the discrete variables achieved good to excellent reliability in both within-session and between-session analysis. Moreover, moderate to strong between-session consistency of subject rankings was found, implying that the measurements assessed during the vertical drop jump demonstrate sufficient reliability to be used in both single-session and multiple-session studies.

    The study explored the psychometric properties of the Eating Disorder Examination Questionnaire (EDE-Q) among 1637 university students. Participants were divided into male (n=432) and female (n=544) competitive athletes, and male (n=229) and female (n=429) comparison groups comprised of individuals who had not engaged in competitive sports for at least one year. All groups were subjected to confirmatory factor analysis (CFA) to test the fit of the published factor structure in this population, and then exploratory FA (EFA). A three-factor solution was the best fit for three out of four groups, with a two-factor solution providing best fit for the male comparison group. The first factor for all groups resembled a combined Shape and Weight Concern subscale. The factor structure among male and female competitive athletes was remarkably similar; however, non-competitive athletic/low activity males appear qualitatively different from other groups.

    The steroid module of the Athlete Biological Passport, the newest innovation in doping testing, is currently being finalized for implementation. Several factors, other than doping, can affect the longitudinal steroid profile. In this study, we investigated the effect of hormonal contraceptives (HC) as well as the effect of three polymorphisms on female steroid profiles in relation to doping controls. The study population consisted of 79 female elite athletes between the ages of 18 and 45. HC were used by 32% of the subjects. A full urinary steroid profile was obtained using World Anti-Doping Agency accredited methods. In addition all subjects were genotyped for copy number variation of UGT2B17 and SNPs in UGT2B7 and CYP17. Subjects using HC excreted 40% less epitestosterone as compared to non-users (p = 0.005) but showed no difference in testosterone excretion. When removing individuals homozygous for the deletion in UGT2B17, the testosterone to epitestosterone (T/E) ratio was 29% higher in the HC group (p = 0.016). In agreement with previous findings in men, copy number variation of UGT2B17 had significant effect on female urinary testosterone excretion and therefore also the T/E ratio. Subjects homozygous for the T allele of CYP17 showed a lower urinary epitestosterone concentration than the other CYP17 genotypes. It is of great importance that the athlete’s steroidal passport can compensate for all possible normal variability in steroid profiles from women. Therefore, considering the large impact of HC on female steroid profiles, we suggest that the use of HC should be a mandatory question on the doping control form. PMID:24782830

    The exercising woman with nutritional deficits and related menstrual irregularities is at risk of compromising long-term bone health, i.e., the female athlete triad. There is no animal model of the female athlete triad. The purpose of this study was to examine long-term energy restriction in voluntary wheel-running female rats on estrous cycling, bone mineral content, and leptin levels. Twelve female Sprague-Dawley rats (age 34 days) were fed ad libitum and given access to running wheels during an initial 14-wk period, providing baseline and age-related data. Daily collection included dietary intake, body weight, estrous cycling, and voluntary running distance. At 4 mo, rats were randomized into two groups, six restrict-fed rats (70% of ad libitum intake) and six rats continuing as ad libitum-fed controls. Energy intake, energy expenditure, and energy availability (energy intake - energy expenditure) were calculated for each animal. Serum estradiol and leptin concentrations were measured by RIA. Femoral and tibial bone mineral density and bone mineral content (BMC) were determined by dual-energy X-ray absorptiometry. Restrict-fed rats exhibited a decrease in energy availability during Weight Loss and Anestrous phases (P = 0.002). Compared with controls after 12 wk, restrict-fed rats showed reduced concentrations of serum estradiol (P = 0.002) and leptin (P = 0.002), lower ovarian weight (P = 0.002), and decreased femoral (P = 0.041) and tibial (P = 0.05) BMC. Decreased energy availability resulted in anestrus and significant decreases in BMC, estrogen and leptin levels, and body weight. Finally, there is a critical level of energy availability to maintain estrous cycling.

    Body composition can affect athletic performance. Numerous studies have documented changes in body composition in female collegiate athletes from pre- to postseason; however, longitudinal studies examining changes across years are scarce. Therefore, the primary purpose of this study was to assess longitudinal body composition changes among female collegiate athletes across 3 years. Two hundred twelve female athletes from basketball (BB; n = 38), soccer (SOC; n = 47), swimming (SW; n = 52), track (sprinters and jumpers; TR; n = 49), and volleyball (VB; n = 26) with an initial mean age of 19.2 ± 1.2 years, height of 172.4 ± 8.9 cm, and total mass of 66.9 ± 9.0 kg had body composition assessments using dual-energy x-ray absorptiometry pre- and postseason over 3 years. A restricted maximum-likelihood linear mixed model regression analysis examined body composition differences by sport and year. Changes (p < 0.05) over 3 years included the following: Lean mass increased in VB from year 1 to 2 (0.7 kg), year 2 to 3 (1.1 kg), and year 1 to 3 (1.8 kg) and in SW from year 1 to 3 (0.6 kg); and percent body fat (%BF) increased in BB from year 1 to 3 (1.7%). There were no changes in SOC or TR. These results indicate that during their college careers, female collegiate athletes can be expected to maintain their %BF and athletes in sports like SW and VB can anticipate an increase in lean mass, but the increases may be less than many athletes, coaches, and trainers envision.

    Numerous reports have described a poor iron status in female endurance athletes. However, the traditionally applied indicators of iron status (hemoglobin, ferritin, transferrin) may not truly reflect the iron status. Therefore we studied the newly developed soluble transferrin receptor and other indicators of iron status in twelve female endurance athletes before and after a triathlon race. Resting values showed a poor iron status in the participants of the race. Serum TfR concentration increased slightly after the race. However, if the values are corrected for hemoconcentration no change could be found. Hemoglobin, serum ferritin and transferrin values were increased after the race.

    Protecting the health of the athlete is a goal of the International Olympic Committee (IOC). The IOC convened an expert panel to update the 2005 IOC Consensus Statement on the Female Athlete Triad. This Consensus Statement replaces the previous and provides guidelines to guide risk assessment, treatment and return-to-play decisions. The IOC expert working group introduces a broader, more comprehensive term for the condition previously known as 'Female Athlete Triad'. The term 'Relative Energy Deficiency in Sport' (RED-S), points to the complexity involved and the fact that male athletes are also affected. The syndrome of RED-S refers to impaired physiological function including, but not limited to, metabolic rate, menstrual function, bone health, immunity, protein synthesis, cardiovascular health caused by relative energy deficiency. The cause of this syndrome is energy deficiency relative to the balance between dietary energy intake and energy expenditure required for health and activities of daily living, growth and sporting activities. Psychological consequences can either precede RED-S or be the result of RED-S. The clinical phenomenon is not a 'triad' of the three entities of energy availability, menstrual function and bone health, but rather a syndrome that affects many aspects of physiological function, health and athletic performance. This Consensus Statement also recommends practical clinical models for the management of affected athletes. The 'Sport Risk Assessment and Return to Play Model' categorises the syndrome into three groups and translates these classifications into clinical recommendations.

    Thirty-five male veteran athletes were studied between 55 and 79 years of age, having exercised track-and-field sports in the amateur class for at least 15 years without interruption. These athletes were divided into power and endurance groups. The subjects examined were compared to a male control group of 30 elderly, healthy persons aged between 51 and 77 years, leading a sedentary lifestyle. All the subjects were submitted to a standard protocol using BOSCO ERGOJUMP. These trials permitted us to evaluate in the laboratory the explosive power of the inferior limbs, maximal alactic and lactic capacities. The results obtained suggest interesting correlations between the unwinding of physical activity and a deterioration of explosive and anaerobic power, above all in subjects over 65 years of age. Therefore, a regular training program could attenuate the modifications and the age-associated decline.

    Research has often examined the relationship between 1 or 2 measures of strength and change of direction (COD) ability reporting inconsistent relationships to performance. These inconsistencies may be the result of the strength assessment used and the assumption that 1 measure of strength can represent all "types" of strength required during a COD task. Therefore the purpose of this study was to determine the relationship between several lower-body strength and power measures, COD, and agility performance. Twelve (n = 12) elite female basketball athletes completed a maximal dynamic back squat, isometric midthigh pull, eccentric and concentric only back squat, and a countermovement jump, followed by 2 COD tests (505 and T-test) and a reactive agility test. Pearson product-moment correlation and stepwise regression analysis were performed on all variables. The percentage contribution of each strength measure to an athletes total strength score was also determined. Our results demonstrated that both COD tests were significantly correlated to maximal dynamic, isometric, concentric, and eccentric strength (r = -0.79 to -0.89), with eccentric strength identified as the sole predictor of COD performance. Agility performance did not correlate with any measure of strength (r = -0.08 to -0.36), whereas lower-body power demonstrated no correlation to either agility or COD performance (r = -0.19 to -0.46). These findings demonstrate the importance of multiple strength components for COD ability, highlighting eccentric strength as a deterministic factor of COD performance. Coaches should aim to develop a well-rounded strength base in athletes; ensuring eccentric strength is developed as effectively as the often-emphasized concentric or overall dynamic strength capacity.

    Controlling dynamic interactions between the lower limb and ground is important for skilled locomotion and may influence injury risk in athletes. It is well known that female athletes sustain anterior cruciate ligament (ACL) tears at higher rates than male athletes, and exhibit lower extremity biomechanics thought to increase injury risk during sport maneuvers. The purpose of this study was to examine whether lower extremity dexterity (LED) – the ability to dynamically control endpoint force magnitude and direction as quantified by compressing an unstable spring with the lower limb at submaximal forces – is a potential contributing factor to the “at-risk” movement behavior exhibited by female athletes. We tested this hypothesis by comparing LED-test performance and single-limb drop jump biomechanics between 14 female and 14 male high school soccer players. We found that female athletes exhibited reduced LED-test performance (p=0.001) and higher limb stiffness during landing (p=0.008) calculated on average within 51 ms of foot contact. Females also exhibited higher coactivation at the ankle (p=0.001) and knee (p=0.02) before landing. No sex differences in sagittal plane joint angles and center of mass velocity at foot contact were observed. Collectively, our results raise the possibility that the higher leg stiffness observed in females during landing is an anticipatory behavior due in part to reduced lower extremity dexterity. The reduced lower extremity dexterity and compensatory stiffening strategy may contribute to the heightened risk of ACL injury in this population. PMID:24275440

    Cerebral blood flow (CBF) is stably maintained through the combined effects of blood pressure (BP) regulation and cerebral autoregulation. Previous studies suggest that aerobic exercise training improves cardiac baroreflex function and beneficially affects BP regulation, but may negatively affect cerebral autoregulation. The purpose of this study was to reveal the impact of lifelong exercise on cardiac baroreflex function and dynamic cerebral autoregulation (CA) in older adults. Eleven Masters athletes (MA) (8 men, 3 women; mean age 73 ± 6 yr; aerobic training >15 yr) and 12 healthy sedentary elderly (SE) (7 men, 5 women; mean age 71 ± 6 yr) participated in this study. BP, CBF velocity (CBFV), and heart rate were measured during resting conditions and repeated sit-stand maneuvers to enhance BP variability. Baroreflex gain was assessed using transfer function analysis of spontaneous changes in systolic BP and R-R interval in the low frequency range (0.05-0.15 Hz). Dynamic CA was assessed during sit-stand-induced changes in mean BP and CBFV at 0.05 Hz (10 s sit, 10 s stand). Cardiac baroreflex gain was more than doubled in MA compared with SE (MA, 7.69 ± 7.95; SE, 3.18 ± 1.29 ms/mmHg; P = 0.018). However, dynamic CA was similar in the two groups (normalized gain: MA, 1.50 ± 0.56; SE, 1.56 ± 0.42% CBFV/mmHg; P = 0.792). These findings suggest that lifelong exercise improves cardiac baroreflex function, but does not alter dynamic CA. Thus, beneficial effects of exercise training on BP regulation can be achieved in older adults without compromising dynamic regulation of CBF.

    The management of osteochondritis dissecans of the capitellum of the adolescent elbow is still controversial. We report on 5 cases of female high-level athletes aged from 10 to 19 years (4 gymnasts, 1 waterpolo player). All these athletes had a symptomatic osteochondritis dissecans of the capitellum, which was treated arthroscopically in all cases. Follow-up time averaged 5 months (1 to 6.5 months). During the arthroscopy, loose osteochondral fragments of the capitellum and radial head were removed, and the defect was debrided. Thorough evaluation of the anterior and posterior joint including the olecranon fossa was performed. One of the 5 patients had a loose body requiring arthroscopic removal. Within 6 months after surgery, all except 1 elbow, the elbow with a loose body, regained maximum range of motion. Two patients returned to a high level of gymnastics and 1 was considering return. The short-term results of this treatment suggest that arthroscopic debridement of the loose osteochondral fragments provides a good result.

    This investigation examined the effect of intramuscular iron injections on aerobic-exercise performance in iron-deficient women. Sixteen athletes performed a 10-min steady-state submaximal economy test, a VO2max test, and a timed test to exhaustion at VO2max workload. Subjects were randomly assigned to an iron-supplemented group (IG) receiving intramuscular iron injections or to a placebo group (PG). Twenty days after the first injection, exercise and blood testing were repeated. A final blood test occurred on Day 28. Post supplementation, no differences were found between the groups' submaximal or maximal VO2, heart rate, or blood lactate (P > 0.05). Time to exhaustion was increased in the IG (P < 0.05) but was not greater than that of the PG (P > 0.05). The IG's serum ferritin (SF) was significantly increased on Days 20 and 28 (mean +/- standard error: 19 +/- 3 to 65 +/- 11 to 57 +/- 12 microg/L; P < 0.01), with a percentage change from baseline significantly greater than in the PG (P < 0.01). It was concluded that intramuscular iron injections can effectively increase SF without enhancing submaximal or maximal aerobic-exercise performance in iron-depleted female athletes.

    Radical, curative surgery may not be considered in elderly patients with gynecologic cancer, yet the morbidity for this population from radiotherapy and cytotoxics may be high. This study compared the feasibility and outcome of such surgery in 226 consecutive patients, 72 women over 70 years old and 154 younger patients, in our institution over a 26-month period. Older patients presented with more advanced-stage cancers and, as a group, had significantly poorer presurgical performance status and more intercurrent medical problems. Nevertheless, the planned radical surgical procedure could be carried out in 90% of elderly patients, with a postoperative mortality of 1.5%. Minor postoperative complication rates were similar for the two groups and, except for vulvectomy patients, the mean inpatient stay was the same for both groups. Chronological age alone is a poor determinant of surgical risk, and elderly patients withstand radical surgery almost as well as their younger counterparts.

    Female athletes are at least as at risk as other women for eating disorders (EDs) and at risk for the female athlete triad (i.e., inadequate energy availability, menstrual disorders, and osteoporosis). This study investigated whether two evidence-based programs appear promising for future study if modified to address the unique needs of female athletes. Athletes were randomly assigned to athlete-modified dissonance prevention or healthy weight intervention (AM-HWI). ED risk factors were assessed pre/post-treatment, and 6-week and 1-year follow-up. Results (analyzed sample, N=157) indicated that both interventions reduced thin-ideal internalization, dietary restraint, bulimic pathology, shape and weight concern, and negative affect at 6 weeks, and bulimic pathology, shape concern, and negative affect at 1 year. Unexpectedly we observed an increase in students spontaneously seeking medical consultation for the triad. Qualitative results suggested that AM-HWI may be more preferred by athletes.

    Sports magazines portrayal of female athletes over the past ten years, in terms of body size, age, and race was examined. Using the Contour Drawing Rating Scale (CDRS), estimated body size was obtained for cover models on a set of judged and non-judged sport magazines. The frequency with which the full bodies of models were depicted on the covers of these magazines was also investigated. Cover models on judged sport magazines were rated as significantly thinner than cover models on non-judged sport magazines. Judged sport magazines also displayed a higher number of full-body images than non-judged sport magazines. These findings suggest that individuals who read judged sport magazines are more likely to be exposed to thin media images than those reading non-judged sport magazines.

    Objective To determine the prevalence of the 3 components of the female athlete triad [disordered eating, menstrual dysfunction, low bone mineral density (BMD)] and their relationships with brachial artery flow-mediated dilation in professional dancers. Design Prospective study. Setting Academic institution in the Midwest. Participants Twenty-two professional ballet dancers volunteered for this study. Interventions The prevalence of the female athlete triad and its relationship to endothelial dysfunction. Main Outcome Measures Subjects completed questionnaires to assess disordered eating and menstrual status/history. They also completed a 3-day food record and wore an accelerometer for 3 days to determine energy availability. Serum baseline thyrotropin, prolactin, and hormonal concentrations were obtained. Bone mineral density and body composition were measured with a GE Lunar Prodigy dual-energy X-ray absorptiometry. Endothelial function was determined as flow-mediated vasodilation measured by high-frequency ultrasound in the brachial artery. An increase in brachial diameter <5% to hyperemic flow stimulus was defined a priori as endothelial dysfunction. Results Seventeen dancers (77%) had evidence of low/negative energy availability. Thirty-two percent had disordered eating (EDE-Q score). Thirty-six percent had menstrual dysfunction and 14% were currently using hormone contraception. Twenty-three percent had evidence of low bone density (Z-score < −1.0). Sixty-four percent had abnormal brachial artery flow-mediated dilation (<5%). Flow-mediated dilation values were significantly correlated with serum estrogen and whole-body and lumbar BMD. All the 3 components of the triad plus endothelial dysfunction were present in 14% of the subjects. Conclusions Endothelial dysfunction was correlated with reduced BMD, menstrual dysfunction, and low serum estrogen. These findings may have profound implications for cardiovascular and bone health in professional women dancers

    Landing awkwardly from a jump is a common mechanism of injury for the anterior cruciate ligament (ACL) of the knee. Augmented feedback, such as verbal or visual instruction, has been shown to cause an immediate, positive change in landing biomechanics in a laboratory setting. No data exist on the longer term effects of feedback on jump landing biomechanics in a sports-specific setting. The purpose of this study was to explore whether providing video and verbal feedback to adolescent (12-14 years old) female volleyball athletes would improve their landing technique. Trunk and lower extremity kinematic variables were measured in 19 participants before a feedback session was provided to the intervention group (IG). Follow-up kinematic measurements of the IG were taken immediately postintervention, and again after 2 and 4 weeks. Two-way repeated measures analysis of variance (ANOVA) was used to compare the IG with a control group (CG), who received no feedback. The IG (n = 10) demonstrated increased maximal hip and trunk flexion compared with the CG (n = 9) at week 4 (p ≤ 0.05). One-way repeated measures ANOVA was used to determine if changes were evident within the IG over time. Ankle dorsiflexion, right knee and hip flexion, and trunk flexion changed significantly (p ≤ 0.05) over the 4-week period. Augmented feedback appeared to produce a positive change in landing biomechanics in adolescent female volleyball athletes performing a sports-specific skill. Courtside video and verbal feedback may present a relatively simple, cost-effective method of introducing one component of a comprehensive ACL injury prevention program at a young age.

    Taekwondo and judo competitions are divided into weight categories. Many athletes reduce their body mass a few days before competition in order to obtain a competitive advantage over lighter opponents. To achieve fast body mass reduction, athletes use a number of nutritional strategies, including choline supplementation. The goal of this study was to identify the effects of choline supplementation on body mass reduction and leptin levels among female taekwondo and judo athletes. Twenty-two female athletes (15 taekwondo and 7 judo athletes) were selected from different weight categories and divided into two groups, according to weight. The players in the experimental group took choline tablets for one week before a competition. The results revealed significant differences between pre- and post-competition measurements of leptin, free plasma choline, urine choline and urine malondialdehyde levels; body mass was also reduced in the post-competition measurements. In conclusion, choline supplementation could rapidly reduce body mass without any side effects on biochemical levels or static strength. PMID:25031675

    Taekwondo and judo competitions are divided into weight categories. Many athletes reduce their body mass a few days before competition in order to obtain a competitive advantage over lighter opponents. To achieve fast body mass reduction, athletes use a number of nutritional strategies, including choline supplementation. The goal of this study was to identify the effects of choline supplementation on body mass reduction and leptin levels among female taekwondo and judo athletes. Twenty-two female athletes (15 taekwondo and 7 judo athletes) were selected from different weight categories and divided into two groups, according to weight. The players in the experimental group took choline tablets for one week before a competition. The results revealed significant differences between pre- and post-competition measurements of leptin, free plasma choline, urine choline and urine malondialdehyde levels; body mass was also reduced in the post-competition measurements. In conclusion, choline supplementation could rapidly reduce body mass without any side effects on biochemical levels or static strength.

    Context Single-sport specialization (SSS) is becoming more prevalent in youth athletes. Deficits in functional movement have been shown to predispose athletes to injury. It is unclear whether a link exists between SSS and the development of functional movement deficits that predispose SSS athletes to an increased risk of knee injury. Objective To determine whether functional movement deficits exist in SSS athletes compared with multi-sport (M-S) athletes. Design Cross-sectional study. Setting Soccer practice fields. Patients or Other Participants A total of 40 (21 SSS [age = 15.05 ± 1.2 years], 19 M-S [age = 15.32 ± 1.2 years]) female high school athlete volunteers were recruited through local soccer clubs. All SSS athletes played soccer. Intervention(s) Participants were grouped into 2 categories: SSS and M-S. All participants completed 3 trials of the standard Landing Error Scoring System (LESS) jump-landing task. They performed a double-legged jump from a 30-cm platform, landing on a rubber mat at a distance of half their body height. Upon landing, participants immediately performed a maximal vertical jump. Main Outcome Measure(s) Values were assigned to each trial using the LESS scoring criteria. We averaged the 3 scored trials and then used a Mann-Whitney U test to test for differences between groups. Participant scores from the jump-landing assessment for each group were also placed into the 4 defined LESS categories for group comparison using a Pearson χ2 test. The α level was set a priori at .05. Results Mean scores were 6.84 ± 1.81 for the SSS group and 6.07 ± 1.93 for the M-S group. We observed no differences between groups (z = −1.44, P = .15). A Pearson χ2 analysis revealed that the proportions of athletes classified as having excellent, good, moderate, or poor LESS scores were not different between the SSS and M-S groups ( = 1.999, P = .57). Conclusions Participation in soccer alone compared with multiple sports did not affect LESS scores in

    The purpose of this study was to examine post-exercise hypotension (PEH) responses to three different resistance exercise velocities in female athletes. The 13 female subjects with experience of resistance training performed a series of resistance exercises with 80% of one repetition maximum for 3 sets with differing in velocity of movements: fast movement (FM; 1-second eccentric and 1-second concentric actions), moderate movement (MM; 1-second eccentric and 2-second concentric actions) and slow movement (SM; 2-second eccentric and 4-second concentric actions). After completing each training session, systolic blood pressure (SBP) and diastolic blood pressure (DBP) were taken every 10 min for a period of 60 min of recovery. The results indicated significant increases in SBP at 10th min post-exercise in comparison to baseline. After 60-min recovery, all conditions showed statistically significant decreases in SBP when compared with pre-exercise. In all measured moments, there were no significant differences among experimental sessions in post-exercise levels of SBP and DBP. Therefore, resistance training with FM, MM, and SM can induce increases in SBP after exercise, whereas after 60-min recovery, can induce decreases in SBP or post-exercise hypotension. PMID:25598990

    Static stretching was once recognized as a method of preparation for physical activity that would inhibit performance and increase risk of injury. However, a growing body of research suggests that static stretching may not have an inhibitory effect. Regardless, the data have not examined gender differences or the fatigue index (FI) and flexibility effects of static stretching on the back squat over multiple sets. Therefore, the purpose of this study was to examine the relationship between a static-stretch condition (SC) and control condition (CC) on flexibility and the FI of Division I female athletes during 4 sets of the back squat. Eighteen subjects (mean ± SD; age 20 ± 1 yrs; height 164.5 ± 14.6 cm; mass 74.1 ± 26.8 kg; waist circumference 73.2 ± 5.4 cm) participated in 3 testing days over the course of 3 weeks. Each subject's 1RM back squat was assessed during the first day of testing and verified during the second. On the third testing day, subjects assigned to the SC held 3 lower-body stretches twice for 30 second intervals and those assigned to the CC rested during the corresponding 7 minutes and 50 second time period. The subjects also performed a fatiguing squat protocol consisting of 4 sets of maximum repetitions on the third day of testing. A significant (p=0.04) interaction was noted for flexibility. No significant interaction (p=0.41) was observed between the FI of the CC (41.8 ± 24.1%) or the SC (27.6 ± 45.2%). These results indicate that static stretching does not have a significant effect on multiple sets of the back squat. Therefore, coaches may allow their athletes to engage in static stretching prior to resistance exercise ad libitum.

    Objective The purpose of this case report is to describe chiropractic rehabilitation of a master's-level athlete with proximal femoral stress fracture and provide a brief discussion of stress fracture pathology. Clinical Features A 41-year-old female master's-level endurance athlete presented with chronic groin pain later diagnosed and confirmed by magnetic resonance imaging as a stress fracture of the femoral neck. After diagnosis, the patient was referred to a doctor of chiropractic at week 1 of the non–weight-bearing physical rehabilitation process. At that time, the patient presented with sharp and constant groin pain rated 6/10 on a numeric rating scale. Intervention and Outcome This patient avoided weight-bearing activity for 8 weeks while cross-training and was able to return to her sport after this period. The patient was progressed through a series of non–weight-bearing strengthening exercises for the lower extremity. Myofascial release therapy was performed on the gluteal, hip flexor, and groin muscle groups to improve range of motion. Motion palpation testing the lumbar and sacroiliac joints was performed during each session, and manipulative therapy was performed when necessary. The patient was seen once a week for 8 weeks. Reevaluation was performed at week 8; at that time, the patient reported no groin pain (0/10). The patient was discharged from care and referred back to the supervising physician for clearance to return to sporting activities. One month after discharge, she reported that she was pain free and had fully returned to sport activities. Conclusion This case report demonstrates the importance of a through clinical history, physical examination, and magnetic resonance imaging in the accurate diagnosis of a patient with chronic groin pain and that chiropractic care can contribute to rehabilitation programs for these injuries.

  10. Iron and the female athlete: a review of dietary treatment methods for improving iron status and exercise performance.

    PubMed

    2015-01-01

    Iron is a functional component of oxygen transport and energy production in humans and therefore is a critically important micronutrient for sport and exercise performance. Athletes, particularly female athletes participating in endurance sport, are at increased risk of compromised iron status due to heightened iron losses through menstruation and exercise-induced mechanisms associated with endurance activity. Conventionally oral iron supplementation is used in prevention or/and treatment of iron deficiency. However, this approach has been criticised because of the side effects and increased risk of iron toxicity associated with the use of supplements. Thus, more recently there has been a growing interest in using dietary modification rather than the use of supplements to improve iron status of athletes. Dietary iron treatment methods include the prescription of an iron-rich diet, or/and haem iron-based diet, dietary advice counselling and inclusion of novel iron-rich products into the daily diet. Although studies using dietary modification are still scarce, current literature suggests that dietary iron interventions can assist in maintaining iron status in female athletes, especially during intensive training and competition. Future research should focus on the most efficient method(s) of dietary modification for improvement of iron status and whether these approaches can have a favourable impact on sports and exercise performance.

    Binocular vision is the most important visual cue for spatial orientation in many sports. In this study, we investigated how binocular vision was influenced by an eye training program that may be used to improve individual's oculomotor function. The experiment involved twenty-four female student athletes from team ball sports (soccer, basketball, handball). After an initial testing session, 12 participants were randomly allocated to the experimental group. Optometric investigation which included synoptophore testing and a test of dissociated horizontal phoria based on the Maddox method was performed three times: before the experiment, after eight weeks of eye training (3 times a week for 20 minutes), and four weeks after the experiment was terminated. Eye exercise methodology was based on orthoptic, sport and psychological aspects of performance. The phoria screening examination showed that exophoria was the most frequent disorder of binocular vision. Low fusional vergence range was also observed. Following the training period, 3 of the 6 oculomotor variables improved. The greatest effect was observed in near dissociated phoria (χ(2) =14.56, p=0.001 for the right eye; χ(2) =14.757, p=0.001 for the left eye) and fusional convergence (χ(2) =8.522, p=0.014). The results of the retention test conducted four weeks after the experiment confirmed the effectiveness of the vision training program. The results of the study suggest that binocular functions are trainable and can be improved by means of appropriate visual training.

  12. Pseudohypertension-Like Presentation: An Exceptionally Rare Presentation in an Athletic Female Patient with Morphea

    PubMed Central

    2016-01-01

    Introduction. Pseudohypertension is a condition which mainly occurs due to thickening-calcification of tunica intima of the arterial wall, leading to a faulty measurement of the intra-arterial blood pressure. To the best of our knowledge, this is the first case report in literature, of a pseudohypertension-like presentation in association with Morphea en plaque. Case Presentation. This is a rare presentation of a young athletic female and a professional tennis player, with pseudohypertension-like presentation. The patient had a traumatic injury to the right elbow joint; the injury occurred during a professional tennis match. The injury was managed by immobilization, physiotherapy, and Low-Level Laser Therapy. Soon after that, the patient had a circumscribed sclerotic ivory plaque affecting the skin of the right cubital fossa. The histopathology analysis, together with the serological-hematological tests and the clinical picture, along with positive Osler's signs, leads to the conclusive diagnosis of Morphea en plaque. The peculiar anatomic localization of the plaque anterior to the brachial artery leads to faulty blood pressure measurement as recorded by mercurial sphygmomanometer. Conclusion. This unique presentation of Morphea en plaque carries an important message in relation to the basic medical practice and in relation to the accurate measurement of the vital signs. PMID:28127475

    This study evaluated levels of plasma zinc, copper, and leptin, body composition, and their relationship in nine elite female judo athletes under two different training conditions. Body composition and biochemical measurements (hematological indexes, plasma zinc, plasma copper, and plasma leptin) were analyzed 24 h after intense training and following a 5-d period without training (no-training). Plasma leptin and plasma zinc increased with no-training. Plasma zinc correlated negatively with percent fat mass (r= -0.62; r=0.05) and positively with plasma leptin (r=0.83; p=0.002) in the no-training condition. Plasma copper did not change during the study and correlated positively with plasma leptin (r=0.66; p=0.05) and with percent fat mass (r=0.80; p=0.007) after training. Percent fat mass was associated negatively with plasma zinc (r=-0.62; p=0.05) in the no-training condition. Moreover, percent fat mass was negatively associated with the Zn/Cu plasma ratio under both training conditions (r< -0.78, p< 0.001). These results are consistent with the possible function of zinc as a lipid-mobilizing factor and of copper as a limiting factor in energy metabolism.

    Low bone-mineral density (BMD) is associated with menstrual dysfunction and negative energy balance in the female athlete triad. This study determines BMD in elite female endurance runners and the associations between BMD, menstrual status, disordered eating, and training volume. Forty-four elite endurance runners participated in the cross-sectional study, and 7 provided longitudinal data. Low BMD was noted in 34.2% of the athletes at the lumbar spine, and osteoporosis in 33% at the radius. In cross-sectional analysis, there were no significant relationships between BMD and the possible associations. Menstrual dysfunction, disordered eating, and low BMD were coexistent in 15.9% of athletes. Longitudinal analysis identified a positive association between the BMD reduction at the lumbar spine and training volume (p=.026). This study confirms the presence of aspects of the female athlete triad in elite female endurance athletes and notes a substantial prevalence of low BMD and osteoporosis. Normal menstrual status was not significantly associated with normal BMD, and it is the authors' practice that all elite female endurance athletes undergo dual-X-ray absorptiometry screening. The association between increased training volume, trend for menstrual dysfunction, and increased loss of lumbar BMD may support the concept that negative energy balance contributes to bone loss in athletes.

    Playing positions in soccer can exhibit different movement demands during a match, contributing to variations in physical and performance characteristics. NCAA soccer features different substitution rules when compared to FIFA-sanctioned matches, which could influence each players' characteristics. Therefore, this study determined the athletic performance characteristics of Division I female soccer players. Twenty-six players (3 goalkeepers; 8 defenders; 10 midfielders; 5 forwards) from the same squad completed assessments of: lower-body power (vertical and standing broad jump); linear (0-5, 0-10, 0-30 meter [m] sprint intervals) and change-of-direction (pro-agility shuttle; Arrowhead change-of-direction speed test) speed; and soccer-specific fitness (Yo-Yo Intermittent Recovery Test [YYIRT] levels 1 and 2). Players were split into position groups, and a Kruskal-Wallis H test with post hoc pairwise analyses (p < 0.05) calculated significant between-group differences. There were no differences in age, height, or body mass between the positions. Midfielders had a faster 0-5 m time compared to the defenders (p = 0.017), and the goalkeepers (p = 0.030). The defenders (p = 0.011) and midfielders (p = 0.013) covered a greater YYIRT2 distance compared to the goalkeepers. There were no other significant between-position differences. Overall, Division I collegiate female players from the same squad demonstrated similar characteristics as measured by soccer-specific performance tests, which could allow for flexibility in position assignments. However, a relatively homogenous squad could also indicate commonality in training prescription, particularly regarding acceleration and high-intensity running. Strength and conditioning coaches may have to consider the specific movement demands of individual positions when training these capacities.

  17. The importance of maximal leg strength for female athletes when performing drop jumps.

    A common suggestion is that a predetermined level of maximal leg strength is required before drop jump (DJ) training can begin. This study sought to examine the relationship between maximal squat strength (1 repetition maximum [RM]) and DJ performance in 15 female rugby players (n = 15). The subjects were tested for 1RM, countermovement jump, squat jump, and DJs from 0.24, 0.36, 0.48, 0.60, 0.72, and 0.84 m. Jump height (JH) was calculated for all jumps and relative peak eccentric force, relative peak concentric force, ground contact time (GCT), and reactive strength index were also calculated for DJs. Pearson correlations were used to examine the relationship between 1RM relative to body mass (BM) (1RM/BM) and JHs, reactive strength index, and GCT during DJs. The subjects were placed in a high strength (HS) or low strength (LS) group depending on whether or not their 1RM/BM was >1 or <1. The T-tests and 2-way analysis of variance (ANOVA) were used to compare the groups. A Fishers post hoc test was used for the ANOVA with significance set at p < 0.05. A large correlation between JH and 1RM/BM was shown at the 0.84-m dropping height (r = 0.56). A significant overall difference was found between the HS and LS groups for DJ JH with a post hoc analysis revealing a significant difference at the 0.84-m drop height (p = 0.029). It is likely beneficial for female athletes to achieve high levels of maximal leg strength if they are going to use high (>0.8-m) drop heights when performing DJs.

    Context: The relationship between generalized joint laxity and plantar pressure distribution of the foot and the potential implications for lower extremity injury have not been studied. Objective: To determine the relationship between generalized joint laxity and dynamic plantar pressure distribution. We hypothesized that individuals with greater generalized joint laxity, or hypermobility, would have greater dynamic medial midfoot pressure and loading during walking than nonhypermobile individuals. Design: Case control. Setting: Institutional biomechanics laboratory. Patients or Other Participants: Participants included 112 female soccer players between 11 and 21 years of age. Main Outcome Measure(s): Each participant was tested for generalized joint laxity using the Beighton and Horan Joint Mobility Index (BHJMI; range, 0–9) and was categorized as having either high (BHJMI score ≥4) or low (BHJMI score <4) generalized joint laxity. Peak pressure and maximum force were calculated from a dynamic, barefoot plantar pressure distribution system. Results: Peak pressure and maximum force were greater in the 27 participants categorized as having high generalized joint laxity than in the 85 participants categorized as having low generalized joint laxity. The midfoot region exhibited greater loading in participants with high generalized joint laxity than in the other participants. We found an effect of BHJMI classification in the medial midfoot; peak pressure in the dominant (F1,109  =  11.262, P  =  .001) and nondominant (F1,109  =  14.32, P < .001) sides and maximum force in the dominant (F1,109  =  7.88, P  =  .006) and nondominant (F1,109  =  9.18, P  =  .003) sides were greater in the high generalized joint laxity group than in the low generalized joint laxity group. Conclusions: Athletes classified as having high generalized joint laxity demonstrated increased midfoot loading. Delineation of risk factors for medial collapse of the foot

    In the present study, we examined developmental and contextual factors that may increase the odds of reporting higher social physique anxiety (SPA) among 404 adolescent athletes 11 to 16 years old. Findings showed older, later maturing athletes past peak height velocity and with greater body mass index (BMI) reported higher SPA. Individual aesthetic sport athletes were older at menarche, had lower BMI, and reported higher SPA. The odds of reporting higher SPA were 4.5 times higher (odds ratio = 4.61) for individual aesthetic sport athletes than for nonaesthetic sport athletes. Team aesthetic sport contexts were not implicated in SPA risk. Results are discussed in terms of self-selection away from individual aesthetic sports and the relevance of physical size and puberty in the SPA construct.

    2016-12-20

    The purpose of the current study was to assess the suitability of the 30-15 IFT as a test in netball using female athletes. 26 female sub-elite netballers (mean age = 19.7 ± 4.6 years, mean height = 176.0 ± 6.1 cm, mean body mass = 69.7 ± 9.3 kg) completed the yo-yo intermittent recovery test level 1 (yo-yo IRT1) and the 30-15 Intermittent Fitness Test (30-15 IFT). Participants performed both assessments one week apart prior to the intervention and both tests one week apart following the training intervention (for a total of four testing sessions). A six-week training intervention occurred between the test occasions. Pearson's correlations revealed significant very large relationships between the 30-15 IFT and yo-yo IRT on both test occasions (test occasion 1: r = 0.71, p = 0.003 (95% CI 0.35 - 0.89), magnitude of effect, most likely; test occasion 2: r = 0.72, p = 0.001 (95% CI 0.42 - 0.88), magnitude of effect, most likely). Repeated measures ANOVAs examining the effect of position on performance changes revealed main effects for test occasion and a position x test occasion interaction for both the 30-15 IFT and the yo-yo IRT1 (30-15 IFT: test occasion (F(1,14) = 28.68, p = 0.001, ηp = .67), position x test occasion interaction (F(2,14) = 9.38, p = 0.003, ηp = .57; yo-yo IRT1: test occasion (F(1,15) = 11.72, p = 0.004, ηp = .44), position x test occasion interaction (F(2,15) = 9.96, p = 0.002, ηp = .57). Results show that the 30-15 IFT is a suitable test for female netballers as it was able to detect improvements in performance after a training intervention, in addition to having a very large significant relationship with the yo-yo IRT1.

    Conflicting results have been documented in the Special Judo Fitness Test (SJFT) for mean parameters of performance between male and female judo athletes matched by age and competitive level. Therefore, it is debatable whether previously established norms for the SJFT prepared for men, should be adopted for use in women. The goal of this investigation was to prepare standards to allow coaches and researchers to control and evaluate training effects in female judoka. Systematic review was used to compile previously published scientific studies containing information on female judo athletes who were tested using the SJFT. The results were derived using meta-analysis and included data obtained from 11 relevant studies published between January 1997 and December 2013. Combined mean and SDs were computed based on studies containing 161 individual results from the SJFT. A 5° scale was adopted as follows: Excellent = highest 5%, Good = next highest 15%, Regular = middle 60%, Poor = next lowest 15%, and Very poor = lowest 5%. The results of the current investigation provide normative data for the SJFT for junior and senior female judoka. Classification for each of the parameters of the SJFT, including number of throws completed during the test, heart rate (HR) measured immediately after the effort, HR after a 1-minute recovery period and SJFT index, were established. This normative data can be used in the design of training programs for female judoka, as well as evaluation after training, and in preparation for competition.

    Objective To determine the relationship between relative body composition and body mass to height, anterior knee pain, or patellofemoral pain (PFP) in adolescent female athletes. Background Patellofemoral pain is common in female athletes and has an undefined etiology. The purpose of this study was to examine whether there was an association among higher body mass index (BMI), BMI z-scores, and relative body fat percentage in the development of PFP in an adolescent female athlete population. We hypothesized that female athletes who developed PFP over the course of a competitive basketball season had higher relative body mass or body fat percentage compared with those who did not develop PFP. Methods Fifteen middle school basketball teams that consisted of 248 basketball players (mean age, 12.76 ± 1.13 years; height, 158.43 ± 7.78 cm; body mass, 52.35 ± 12.31 kg; BMI, 20.73 ± 3.88 kg/m2) agreed to participate in this study over the course of 2 basketball seasons, resulting in 262 athlete-seasons. Testing included the completion of the Anterior Knee Pain Scale (AKPS), International Knee Documentation Committee (IKDC) form, standardized history, physician-administered physical examination, maturational estimates, and anthropometrics. Results Of the 262 athlete-seasons monitored, 39 athletes developed PFP over the course of the study. The incidence rate of new PFP was 1.57 per 1000 athlete-exposures. The cumulative incidence of PFP was 14.9%. There was no difference in BMI between those who developed PFP (mean body mass, 20.2 kg/m2; 95% CI, 18.9–21.4) and those who did not develop PFP (mean body mass, 20.8 kg/m2; 95% CI, 20.3–21.3; P > 0.05). Body mass index z-scores were not different between those who developed PFP (mean, 0.3; 95% CI, 0.7–0.6) and those who did not develop PFP (mean, 0.4; 95% CI, 0.3–0.6; P > 0.05). A similar trend was noted in relative body fat percentage, with mean scores of similar ranges in those who developed PFP (mean body fat

    Female gender and younger age are protective factors against disease progression in chronic hepatitis B (CHB). However, it is not clear whether the disease progression still remains slow in elderly females. This study investigated the interaction of female gender and older age on the development of cirrhosis in patients recorded in China Registry of Hepatitis B. A total of 17,809 CHB patients were enrolled in this multi-center cross-sectional study. The prevalence of cirrhosis in female CHB patients increased faster than that in male CHB patients over 50 years old. Multivariate analysis showed that the increase of adjusted ORs for developing cirrhosis in females started to accelerate after 50 years old: 11.19 (95% CI: 5.93–21.11) in women versus 14.75 (95% CI: 8.35–26.07) in men at ages of 50–59 years, 21.67 (95% CI: 11.05–42.47) versus 24.4 (95% CI: 13.00–45.80) at ages 60–69 years, and 18.78 (95% CI: 6.61–53.36) versus 12.09 (95% CI: 4.35–33.61) in those over 70 years. In conclusion, the protective effect of female gender against cirrhosis gradually lost with increasing age, therefore disease progression should be monitored more closely in elderly women with CHB.

    INTRODUCTION: Despite the growing popularity of off-road running events, little information is available about the physiological stress of such activities. The demands of such events are unique in terms of the rough surface of the terrain encountered as well as the underfoot vegetation and the gradient. OBJECTIVES: The aim of this study was to investigate the physiological response of female athletes, as measured by heart rate, to three common off-road running events: cross country running (n = 15), fell running (n = 20), and orienteering (n = 25). METHODS: Heart rate responses were recorded during cross country and fell races, and orienteering by means of short range radiotelemetry. Road running (n = 21) was also studied as a reference. RESULTS: The mean heart rates for each event varied with the differing demands of the terrain. The highest (182 (10) beats/minute; mean (SD)) was for road running and the lowest (172 (10) beats/minute) for orienteering. Orienteering evoked a significantly more variable response than all other events (F4,100 = 112.4; p<0.01), with a range of 44 beats/minute (142-186 beats/minute) in the heart rate. This may be due to both the variability of the terrain and the additional technical aspect of this sport. There was a positive trend in the slope of the regression lines of heart rate against time for both road and cross country running, which was not evident in the fell runners or the orienteers. The latter events demonstrated no consistent pattern. CONCLUSIONS: It is concluded that running off-road elicits a heart rate response that varies with the altering demands of surface, vegetation, and gradient.

    The timing of morning endurance competition may limit proper pre-race fueling and resulting performance. A nighttime, pre-sleep nutritional strategy could be an alternative method to target the metabolic and hydrating needs of the early morning athlete without compromising sleep or gastrointestinal comfort during exercise. Therefore, the purpose of this investigation was to examine the acute effects of pre-sleep chocolate milk (CM) ingestion on next-morning running performance, metabolism, and hydration status. Twelve competitive female runners and triathletes (age, 30 ± 7 years; peak oxygen consumption, 53 ± 4 mL·kg(-1)·min(-1)) randomly ingested either pre-sleep CM or non-nutritive placebo (PL) ∼30 min before sleep and 7-9 h before a morning exercise trial. Resting metabolic rate (RMR) was assessed prior to exercise. The exercise trial included a warm-up, three 5-min incremental workloads at 55%, 65%, and 75% peak oxygen consumption, and a 10-km treadmill time trial (TT). Physiological responses were assessed prior, during (incremental and TT), and postexercise. Paired t tests and magnitude-based inferences were used to determine treatment differences. TT performances were not different ("most likely trivial" improvement with CM) between conditions (PL: 52.8 ± 8.4 min vs CM: 52.8 ± 8.0 min). RMR was "likely" increased (4.8%) and total carbohydrate oxidation (g·min(-1)) during exercise was "possibly" or likely increased (18.8%, 10.1%, 9.1% for stage 1-3, respectively) with CM versus PL. There were no consistent changes to hydration indices. In conclusion, pre-sleep CM may alter next-morning resting and exercise metabolism to favor carbohydrate oxidation, but effects did not translate to 10-km running performance improvements.

  11. Current perspectives on the etiology and manifestation of the “silent” component of the Female Athlete Triad

    2014-01-01

    The Female Athlete Triad (Triad) represents a syndrome of three interrelated conditions that originate from chronically inadequate energy intake to compensate for energy expenditure; this environment results in insufficient stored energy to maintain physiological processes, a condition known as low energy availability. The physiological adaptations associated with low energy availability, in turn, contribute to menstrual cycle disturbances. The downstream effects of both low energy availability and suppressed estrogen concentrations synergistically impair bone health, leading to low bone mineral density, compromised bone structure and microarchitecture, and ultimately, a decrease in bone strength. Unlike the other components of the Triad, poor bone health often does not have overt symptoms, and therefore develops silently, unbeknownst to the athlete. Compromised bone health among female athletes increases the risk of fracture throughout the lifespan, highlighting the long-term health consequences of the Triad. The purpose of this review is to examine the current state of Triad research related to the third component of the Triad, ie, poor bone health, in an effort to summarize what we know, what we are learning, and what remains unknown.

    An overview of the Pediatric Endocrine Society's Ethics Symposium held in April 2015 at the annual meeting of the Pediatric Academic Societies is provided by the panel moderators with a summary of efforts by international athletic governing bodies over several decades to 'verify' the eligibility of athletes to compete in female only events, culminating in the hyperandrogenism policies that were the focus of the panel debate. This history was extensively reviewed in the symposium's opening presentation by Alan Rogol, in collaboration with Lindsay Pieper. Two sharply divergent views were then conveyed. David Allen's, in support, is provided in his article which follows. The opposing case, provided by Katrina Karkazis, is extensively summarized herein and reflected in her Science essay with Rebecca Jordan-Young which appeared shortly after the meeting. The subsequent ruling by the international Court of Arbitration for Sport to suspend the hyperandrogenism rule is noted with some speculation regarding the implications if it is upheld.

    The purpose of this study was to examine the effects of a neuromuscular training program on movement competency and measures of physical performance in youth female netball players. It was hypothesized that significant improvements would be found in movement competency and physical performance measures following the intervention. Twenty-three junior female netball players (age, 12.17 ± 0.94 yrs; height, 1.63 ± 0.08 m; weight, 51.81 ± 8.45 kg) completed a test battery before and after a six-week training intervention. 13 of these athletes underwent six weeks of neuromuscular training, which incorporated plyometrics and resistance training. Trained athletes showed significant improvements in 20 m sprint time, 505 agility time, countermovement jump height and peak power (p ≤ 0.05, g > 0.8). Additionally, trained athletes significantly improved their score in the Netball Movement Screening Tool (NMST) (p < 0.05, g > -1.30); while the athletes also demonstrated increased reach in the anterior and posteromedial directions for the right and left leg, and in the posterolateral direction for the left leg only in the Star Excursion Balance Test (SEBT) (p < 0.05, g > -0.03). Control subjects did not exhibit any significant changes during the 6-week period. Significant negative correlations were found between improved score on the NMST and decreased 5 m, 10 m and 20 m sprint time, and 505 change of direction time (r > 0.4, p ≤ 0.05). Results of the study affirm the hypothesis that a six-week neuromuscular training intervention can improve performance and movement competency in youth netball players.

    Thirty-six adults (24 males, 12 females) were assessed for anthropometric somatotype and body image (perception and satisfaction) by a novel technique using quantitative distortion of a digital still image. Software produced random distortions in nine body regions. The participants manipulated interactive slider controls to adjust each body feature in turn, recreate their perceived image and indicate their desired image. There were no differences in perception between the sexes. However, the ideal-actual differences (i.e. satisfaction) indicated that males desired larger and females smaller features, respectively, in the chest and thighs (P < 0.001) and arms and calves (P < 0.01). When the male-derived data were partitioned by sport (strength, endurance, team-sport and controls), differences were found in the perceived image size in the chest and rib regions (P < 0.01 and P < 0.05, respectively). Strength athletes perceived these areas to be smaller and the control group perceived these areas to be larger than the true values. Somatotype analysis indicated that the physique associated with minimal dissatisfaction was 2.0-5.0-3.0 for males and 3.0-2.5-3.0 for females. Cluster analysis, combining anthropometric and satisfaction data, revealed seven distinct subgroups distinguished by particular attributes of physical appearance. We conclude that the method is reliable and that body image includes sex-specific, anthropometric, perceptual and personality-related components.

    The current study examined associations among sports participation (SP), athletic identity (AI), weight status, and eating pathology, and whether these relations differed by gender. Data come from male and female first-year college students who participated in the Tufts Longitudinal Health Study (TLHS) between 1999-2007 (N=712). Relations among SP, AI, actual and perceived weight statuses, Eating Disorders Inventory (EDI) subscale scores, and indices of body shape concern and restrictive eating were examined with hierarchical ordinary least squares (OLS) regression. Associations between SP and eating pathology among females were moderated by perceived weight status. By contrast, relations between males' EDI subscales scores and SP were moderated by ethnicity, as well as by actual weight status. Our findings support that sports participation alone neither promotes nor protects against eating pathology among males and females.

    The aim of this study was to investigate the effect of a season of cross-country training and racing on airway inflammation, cough symptoms, and athlete quality of life in female skiers. Eighteen elite female skiers performed sputum induction and completed the Leicester Cough Questionnaire (LCQ) and the Recovery-Stress Questionnaire (REST-Q) at three time points (T1 - May/Jun, T2 - Oct/Nov, T3 - Jan-Mar) during the year. No changes were observed between T1 and T2. However, an increase in sputum eosinophils and lymphocytes (P < 0.05) and a significant change in all three domains of the LCQ were observed between T1 and T3 (P < 0.05). A significant association was found between the total yearly hours of training and the change in the total cell count (r(2)  = 0.74; P = 0.006), and a number of other sputum cell counts between T1 and T3. No changes were observed for any domain of the REST-Q. The results of this study demonstrate that airway inflammation and cough symptoms are significantly increased in elite female cross-country skiers across a year of training and racing. The increase in airway inflammation is related to the total amount of training and is worse during the winter months when athletes are training and racing in cold, dry air.

    [Purpose] The present paper reviews the physiological adaptation to swim training and dietary supplementation relating to bone mineral density (BMD) in female swimmers. Swim training still seems to have conflicting effects on bone health maintenance in athletes. [Methods] This review article focuses on swim training combined with dietary supplementation with respect to BMD in female athletes. [Results] Upon review of previous studies, it became obvious that the majority of studies did not collect physical activity data on the swimmers outside of their swimming activities. These activities may have some influence on the BMD of swimmers and therefore, future studies need to examine additional physical activity history data as well as swim training. This additional information may help to explain why swimmers' BMD tends to be lower than the BMD of control individuals in many studies. Moreover, dietary supplementation such as calcium, magnesium, and vitamin D also affect bone health in swimmers, and it is extremely important to evaluate BMD in the context of dietary supplementation. [Conclusion] A review of the literature suggests that exercise intervention studies, including longitudinal and randomized control trials, need to attempt to introduce various exercise programs to female swimmers in order to determine the optimal exercise prescription for bone health.

    Exercise regimens suitable to the elderly remain under investigated; therefore, this study examined the effects of Dance Dance Revolution (DDR) on cognitive control in elderly females. Twenty-six healthy elderly females leading a sedentary lifestyle were assigned to a DDR, brisk walking, or control group. Participants in the DDR and brisk walking groups engaged in moderate physical exercise three times per week for 3 months, whereas the control group maintained a sedentary lifestyle. Each participant performed a flanker task before and after the intervention. The results revealed that both DDR and brisk walking shortened reaction time, N2 latency, and P3 latency relative to those of the control group. These findings suggest that DDR intervention is as effective as that of brisk walking in improving inhibitory control for elderly people. Therefore, DDR can be used as a viable alternative exercise to enhance cognitive function for the elderly and motivate individuals who are less willing to be active.

    Background Women who participate in high-risk sports suffer anterior cruciate ligament injury at a 4- to 6-fold greater rate than men. Purpose To prospectively determine if female athletes with decreased passive knee joint restraint (greater joint laxity) and greater side-to-side differences in knee laxity would be at increased risk of anterior cruciate ligament injury. Study Design Case control study; Level of evidence, 3. Methods From 1558 female soccer and basketball players who were prospectively screened, 19 went on to tear their anterior cruciate ligaments. Four height- and mass-matched control subjects were selected from the uninjured screened athletes for comparison with each of the 19 injured subjects, making a total of 95 subjects (19 injured; 76 uninjured). Generalized joint-laxity tests and anterior-posterior tibiofemoral translation were quantified using the CompuKT knee arthrometer. A multivariable logistic regression model was constructed to determine predictors of anterior cruciate ligament injury status from recorded laxity measures. Results A multivariable logistic regression model (chi-square = 18.6; P = .002) used the independent variables laxity measures of knee hyperextension (P = .02), wrist and thumb to forearm opposition (P = .80), fifth-finger hyperextension >90° (P = .71), side-to-side differences in anterior-posterior tibiofemoral translation (P = .002), and prior knee injury (P = .22) to predict anterior cruciate ligament–injury status. The validated C statistic, or validated area under the receiver operating characteristic curve, was 0.72. For every 1.3-mm increase in side-to-side differences in anterior-posterior knee displacement, the odds of anterior cruciate ligament–injured status increased 4-fold (95% confidence interval, 1.68–9.69). A positive measure of knee hyperextension increased the odds of anterior cruciate ligament–injured status 5-fold (95% confidence interval, 1.24–18.44). Conclusion The current results

    The pelvic floor (PF) provides support to all pelvic organs, as well as appropriately closure/opening mechanism of the urethra, vagina, and anus. Therefore, it is likely that female athletes involved in high-impact and in strong-effort activities are at risk for the occurrence of urinary incontinence (UI). This study aimed to investigate the occurrence of UI and other PF dysfunctions (PFD) [anal incontinence (AI), symptoms of constipation, dyspareunia, vaginal laxity, and pelvic organ prolapse] in 67 amateur athletes (AT) compared with a group 96 of nonathletes (NAT). An ad hoc survey based on questions from reliable and valid instruments was developed to investigate the occurrence of PFD symptoms. The risk of UI was higher in AT group (odds ratio: 2.90; 95% CI: 1.50-5.61), mostly among artistic gymnastics and trampoline, followed by swimming and judo athletes. Whereas, AT group reported less straining to evacuate (OR: 0.46; 95% CI: 0.22-0.96), manual assistance to defecate (OR: 0.24; 95% CI: 0.05-1.12), and a higher stool frequency (OR: 0.29; 95% CI: 0.13-0.64) than NAT group. The occurrence of loss of gas and sexual symptoms was high for both groups when compared with literature, although with no statistical difference between them. Pelvic organ prolapse was only reported by nonathletes. Athletes are at higher risk to develop UI, loss of gas, and sexual dysfunctions, either practicing high-impact or strong-effort activities. Thus, pelvic floor must be considered as an entity and addressed as well. Also, women involved in long-term high-impact and strengthening sports should be advised of the impact of such activities on pelvic floor function and offered preventive PFD strategies as well.

    The aim of the study was to determine canonic relations between the set of basic motor variables and the set of athletic variables assessing the abilities of sprint, throw and long-distance run adjusted for children aged seven years. Study sample consisted of 635 first-graders from Split elementary schools, divided into groups of 325 male and 310 female subjects. The set of nine variables of the basic motor space and three variables of situation motoricity in athletics were applied at the beginning and at the end of the academic year. Association between the sets of variables was determined by canonic correlation analysis. In male subjects, association between the sets of variables revealed a predominant effect of explosive strength on the sprint and throw ability on initial measurement. On final measurement, association in the first pair of canonic dimensions was underlain by the favorable impact of all strength factors with a predominance of explosive strength, which was accompanied by the development of flexibility and coordination, influencing performance in sprint and throwing; the second canonic variable was bipolar, differentiating aerobic endurance ability determined by above-average flexibility, frequency of lower extremity movements and static strength, and throwing ability determined by above-average equilibrium, explosive strength, coordination and repetitive strength. In female subjects, on initial measurement association in the first pair of canonic dimensions was mostly determined by the effect of explosive strength, repetitive strength of the trunk and movement frequency on general ability in athletics defined by the abilities of sprint, throw and long-distance run. Association in the second pair of canonic dimensions was determined by the impact of explosive strength and flexibility on sprint performance on the one hand, and by the effect of movement frequency and repetitive strength of the trunk on long-distance run performance on the other hand

    To determine whether there is a direct correlation between endurance capacity and cold tolerance, maximal oxygen consumption (VO2max), and cold-induced vasodilatation (CIVD), we measured these factors in 14 young female athletes born in Hokkaido, Japan's northernmost island. We determined the VO2max by a standard incremental test on a cycle ergometer and measured the oxygen consumption (VO2) by means of the Douglas-bag method. We determined the CIVD reaction by measuring the skin temperature of the left middle finger during immersion in cold water at 0°C for 20 min. The athletes showed significant positive correlations between VO2max, expressed as l/min, and CIVD as well as other peripheral cold tolerance indexes (resistance index against frostbite and CIVD index). The body weight VO2max (VO2max/kg body weight) failed to correlate significantly with either the CIVD or with other cold tolerance indexes. These results suggest that CIVD in females may depend on factors other than those determined in this study, in addition to the functional spread of the vascular beds in peripheral tissues, including striated muscle; it is known that the size and the vascular bed in this tissue are affected by exercise training and that this results in the elevation of VO2max and VO2max/kg body weight.

    Tardive oromandibular dystonia (OMD) is iatrogenic in origin and is characterised by orofacial and lingual stereotypes more frequently than the idiopathic form of OMD Tardive OMD is often associated with anti-dopaminergic treatment involving drugs such as anti-psychotics, anti-emetics, and anti-vertigo agents, although the syndrome can also be triggered by anti-epileptic or anti-depressant drugs that do not have anti-dopaminergic properties. We report an elderly female patient with OMD after prolonged, self-administered treatment with betahistine dihydrochloride, a histamine analogue.

    The aim of the study was to determine the importance of two sport-associated gene polymorphisms, alpha-actinin-3 R577X (ACTN3) and angiotensin-converting enzyme I/D (ACE), among Hungarian athletes in different sports. The examination was carried out only on women (n = 100). Sport-specific groups were formed in order to guarantee the most homogeneous clusters. Human genomic DNA was isolated from blood, and genotyping was performed by polymerase chain reaction. To measure the differences between the participating groups, Chi-squared test was performed using Statistica 9.0 for Windows® (significance level: p < 0.05). In comparing the ACE I/D allele frequencies, significant difference was detected between water polo (I = 61.11%; D = 38.89%) and combat sports (I = 35.71%, D = 64.29%) athletes (p < 0.03). There was no statistical difference when ACE I/D alleles in combat sports and kayaking/rowing (p > 0.05) were compared. A similarity was detectable in the I allele frequencies of the water polo (61.11%) and kayaking/rowing (56.67%) groups. The ACTN3 R/X polymorphism showed no differences in comparison with the sport groups. R allele frequencies were higher in every group compared to the X allele. The potential significance of the ACE I allele in sports of an aerobic nature was not clearly confirmed among Hungarian athletes.

    Aims Low-weight hypogonadal conditions such as anorexia nervosa are associated with marked changes in body composition, hemodynamic and hematological parameters, and liver enzymes. The impact of athletic activity in normal-weight adolescents with/without amenorrhea on these parameters has not been assessed. Our aim was to examine these parameters in normal-weight athletes and non-athletes and determine any associations of body composition, oligo-amenorrhea and exercise intensity. Methods We assessed vital signs, complete blood counts, liver enzymes, and regional body composition in 43 oligo-amenorrheic athletes (OAA), 24 eumenorrheic athletes (EA) and 23 non-athletes 14-21 years of age. Results BMI was lower in OAA than EA. Systolic and pulse pressure, and temperature were lowest in OAA. Blood counts did not differ among groups. AST was higher in both groups of athletes, while ALT was higher in OAA than EA and non-athletes. Total and regional fat was lower in OAA than other groups, positively associated with heart rate and inversely with liver enzymes. Conclusions Athletic activity is associated with higher AST, whereas menstrual dysfunction is associated with lower total and regional fat and higher ALT. Higher liver enzymes are associated with reductions in total and regional fat. PMID:25376841

    The purpose of this study was to examine gender differences in repeated sprint exercise (RSE) performance among male and female athletes matched for VO2max relative to FFM (VO2max FFM). Thirty nine male and female college athletes performed a graded exercise test for VO2max and hydrostatic weighing to determine FFM. From the results, 11 pairs of males and females matched for VO2max FFM (mean ± SD; 58.3 ± 4.3 and 58.9 ± 4.6 ml·kg FFM(-1)·min(-1); men and women, respectively) were identified. On a separate day, matched participants performed a RSE protocol that consisted of five 6-sec cycle sprints with 30-sec recovery periods, followed by 5-min active recovery and a 30-sec all-out sprint. Repeated 6-sec sprint performance did not differ between men and women; both maintained power output (PO) until sprint 4. POFFM (W·kg(-1) FFM) did not differ between men and women during the five sprints. During the 30-sec sprint, men achieved a lower peak POFFM than women (11.7 ± 1.5 vs 13.2 ± 1.2); however, the decline in POFFM over 30 sec was greater in women. VO2 (ml·kg FFM(-1)·min(-1)) was lower in men during recovery (24.4 ± 3.8 vs 28.7 ± 5.7) and at the beginning (29.2 ± 4.0 vs 34.7 ± 4.9) and end (49.4 ± 5.0 vs 52.3 ± 4.0). of the 30-sec sprint. These data indicate that men and women with similar aerobic capacities do not respond differently to short repeated sprints but may differ in their ability to recover and perform sprints of longer duration.

    The Special Judo Fitness Test (SJFT) has become the test most widely used by coaches and physical trainers for assessment of competitors’ judo-specific physical aptitude and training programme prescription. The aim of this study was to investigate the relationship between the SJFT performance indices and both maximal aerobic power and the level of blood lactate concentrations in female judo athletes. Seventeen female judokas (age: 21.9±1.6 years, body mass: 74.6±27.4 kg, height: 164.5±8.6 cm; BMI: 27.1±8.0 kg · m-2) took part in this study. All participants performed the SJFT, 20 m multi-stage shuttle run test (MSRT), and 30 m straight sprint test (SST), from which we calculated both acceleration (10 m) and the maximal anaerobic speed (MAnS: flying 20 m sprint). A blood sample was taken 3 min after the SJFT. The number of throws was significantly correlated with estimated VO2max (r=0.795, p=0.0001) and both acceleration (r=0.63, p =0.006) and MAnS (r=0.76, p=0.0004). Peak blood lactate recorded after the SJFT was 13.90±1.39 mmol · l-1. No significant correlation was found between blood lactate concentration and the SJFT performance indices. The lack of significant correlation between blood lactate and SJFT performance suggests that lactic anaerobic metabolism has no effect on this type of judo-specific supra-maximal exercise. The observed results can provide coaches and strength and conditioning professionals with relevant information for the interpretation of SJFT performance and the prescription of specific training programmes for female judo athletes.

    The objective of this study was to investigate the gender-specific differences in peak torque (PT), muscle stiffness (MS) and musculoarticular stiffness (MAS) of the knee joints in a young active population. Twenty-two male and twenty-two female recreational athletes participated. PT of the knee joint extensor musculature was assessed on an isokinetic dynamometer, MS of the vastus lateralis (VL) muscle was measured in both relaxed and contracted conditions, and knee joint MAS was quantified using the free oscillation technique. Significant gender differences were observed for all dependent variables. Females demonstrated less normalized PT (mean difference (MD)=0.4Nm/kg, p=0.005, η(2)=0.17), relaxed MS (MD=94.2N/m, p<.001, η(2)=0.53), contracted MS (MD=162.7N/m, p<.001, η(2)=0.53) and MAS (MD=422.1N/m, p<.001, η(2)=0.23) than males. MAS increased linearly with the external load in both genders with males demonstrating a significantly higher slope (p=0.019) than females. The observed differences outlined above may contribute to the higher knee joint injury incidence and prevalence in females when compared to males.

    This investigation evaluated the effects of a 4-week, 12-session training program using resisted sprint training (RST), assisted sprint training (AST), and traditional sprint training (TST) on maximal velocity and acceleration in National Collegiate Athletic Association (NCAA) Division IA female soccer athletes (n = 27). The subjects, using their respective training modality, completed 10 maximal effort sprints of 20 yd (18.3 m) followed by a 20-yd (18.3 m) deceleration to jog. Repeated measures multivariate analyses of variance and analyses of variance demonstrated significant (p < 0.001) 3-way interactions (time × distance × group) and 2-way interactions (time × group), respectively, for both velocity and acceleration. Paired t-tests demonstrated that maximum 40-yd (36.6-m) velocity increased significantly in both the AST (p < 0.001) and RST (p < 0.05) groups, with no change in the TST group. Five-yard (4.6-m), 15-yd (13.7 m), 5- to 15-yd (4.6- to 13.7-m) acceleration increased significantly (p < 0.01) in the AST group and did not change in the RST and TST groups. Fifteen- to 25-yd (13.7- to 22.9-m) acceleration increased significantly (p < 0.01) in the RST group, decreased significantly (p < 0.01) in the AST group, and was unchanged in the TST group. Twenty-five to 40-yd (22.9- to 36.6-m) acceleration increased significantly (p < 0.05) in the RST group and remained unchanged in the AST and TST groups. It is purposed that the increased 5-yd (4.6-m) and 15-yd (13.7-m) accelerations were the result of enhanced neuromuscular facilitation in response to the 12-session supramaximal training protocol. Accordingly, it is suggested that athletes participating in short distance acceleration events (i.e., ≤15 yd; ≤13.7 m) use AST protocols, whereas athletes participating in events that require greater maximum velocity (i.e., >15 yd; > 13.7 m) should use resisted sprint training protocols.

    Purpose The purpose of the current study was to investigate the effects of adding strength training to normal endurance training on running performance and running economy in well-trained female athletes. We hypothesized that the added strength training would improve performance and running economy through altered stiffness of the muscle-tendon complex of leg extensors. Methods Nineteen female endurance athletes [maximal oxygen consumption (VO2max): 53±3 ml∙kg-1∙min-1, 5.8 h weekly endurance training] were randomly assigned to either normal endurance training (E, n = 8) or normal endurance training combined with strength training (E+S, n = 11). The strength training consisted of four leg exercises [3 x 4–10 repetition maximum (RM)], twice a week for 11 weeks. Muscle strength, 40 min all-out running distance, running performance determinants and patellar tendon stiffness were measured before and after the intervention. Results E+S increased 1RM in leg exercises (40 ± 15%) and maximal jumping height in counter movement jump (6 ± 6%) and squat jump (9 ± 7%, p < 0.05). This was accompanied by increased muscle fiber cross sectional area of both fiber type I (13 ± 7%) and fiber type II (31 ± 20%) in m. vastus lateralis (p < 0.05), with no change in capillary density in m. vastus lateralis or the stiffness of the patellar tendon. Neither E+S nor E changed running economy, fractional utilization of VO2max or VO2max. There were also no change in running distance during a 40 min all-out running test in neither of the groups. Conclusion Adding heavy strength training to endurance training did not affect 40 min all-out running performance or running economy compared to endurance training only. PMID:26953893

    The purpose of the study was to investigate the effect of an overhead target on the jump height and lower limb biomechanics in all three planes of motion in a vertical drop jump (VDJ) task among elite female handball and football (soccer) players. The hypothesis was that adding an overhead target to the VDJ task improves jump height, increases joint loading, and decreases frontal plane knee control. Five hundred and twenty-three female handball and football players (mean ± SD: 21 ± 4 years, 168 ± 6 cm, 65 ± 8 kg) completed the test. The overhead target increased jumping height by 5.8%. Furthermore, the overhead target led to statistically significant changes in many of the lower limb biomechanical variables examined. However, all the changes in kinematics and kinetics were clinically insignificant, as indicated by the small effect sizes. Strong to moderate positive Spearman's rank correlations were found between the two conditions. Therefore, an overhead target is unlikely to increase the range of responses in biomechanical variables in elite female handball and football athletes.

Validity of urine specific gravity when compared with plasma osmolality as a measure of hydration status in male and female NCAA collegiate athletes. J Strength Cond Res 30(8): 2219-2225, 2016-The purpose of this study was to evaluate the response of urine specific gravity (Usg) and urine osmolality (Uosm) when compared with plasma osmolality (Posm) from euhydration to 3% dehydration and then a 2-hour rehydration period in male and female collegiate athletes. Fifty-six National Collegiate Athletic Association (NCAA) wrestlers (mean ± SEM); height 1.75 ± 0.01 m, age 19.3 ± 0.2 years, and body mass (BM) 78.1 ± 1.8 kg and 26 NCAA women's soccer athletes; height 1.64 ± 0.01 m, age 19.8 ± 0.3 years, and BM 62.2 ± 1.2 kg were evaluated. Hydration status was obtained by measuring changes in Posm, Uosm, Usg, and BM. Male and female subjects dehydrated to achieve an average BM loss of 2.9 ± 0.09% and 1.9 ± 0.03%, respectively. Using the medical diagnostic decision model, the sensitivity of Usg was high in both the hydrated and dehydrated state for males (92%) and females (80%). However, the specificity of Usg was low in both the hydrated and dehydrated states for males (10 and 6%, respectively) and females (29 and 40%, respectively). No significant correlations were found between Usg and Posm during either the hydrated or dehydrated state for males or females. Based on these results, the use of Usg as a field measure of hydration status in male and female collegiate athletes should be used with caution. Considering that athletes deal with hydration status on a regular basis, the reported low specificity of Usg suggests that athletes could be incorrectly classified leading to the unnecessary loss of competition.

    Abstract Background In the case of the elderly who highly depend on family, serious health problems can be caused due to the reduction of family meals. Therefore, this study aims to suggest the fundamental data for management of cardiovascular disease, one of the major causes of death in elderly Koreans, by investigating the effects of family meal frequency on the risk factors for cardiovascular disease in Korean elderly males and females. Methods The raw data of the Fifth Korea National Health and Nutrition Examination Survey (KNHANES III) were utilized. Data of 1,236 respondents were extracted for analysis regarding anthropometry, blood, blood pressure, nutrients and total energy intake. For collected data, using SPSS 18.0 and Amos 18.0, the mean and standard deviation, and the path coefficient between groups through a multi-group analysis by structural equation model were checked Results As family meal frequency increased, triglyceride and fasting blood glucose in Korean elderly males were likely to decrease, which led to conflicting results with those of Korean elderly females. Conclusion Frequent family meal makes a positive effect on reducing several risk factors for cardiovascular disease in Korean elderly. PMID:26060777

    The incidence of spontaneous perforations in pyometra is rare, being 0.01-0.5% in gynaecological patients. However, they are more common in postmenopausal females and their incidence is 13.6%. Here, we are reporting a rare case of peritonitis with a pneumoperitoneum in an elderly female, which was caused by a spontaneous perforation of pyometra. A 74-years old postmenopausal female with uncontrolled diabetes mellitus was admitted to surgical emergency with signs of diffuse peritonitis and she was in shock. After resuscitation, an emergency laparotomy was performed because of suspicion of a hollow viscous perforation with peritonitis. At laparotomy, about 2000ml of purulent fluid was found to be present in peritoneal cavity, while alimentary tract was intact. A rent with a diameter of 0.8 cm was found on fundus of uterus. A total abdominal hysterectomy with a bilateral salphingo oophorectomy was performed. Patient got discharged on 12(th) post-operative day without major complications. Histopathological studies revealed endometritis and myometritis, with no evidence of malignancy.

    [Purpose] This study investigated the flexion-relaxation phenomenon of the erector spinae in elderly women with chronic knee osteoarthritis and determined whether the flexion-relaxation phenomenon can be used as a pain evaluation tool in such cases. [Subjects and Methods] Seventeen elderly females with chronic knee osteoarthritis and 13 healthy young females voluntarily participated in this study. They performed three postural positions in 15 s: trunk flexion, complete trunk flexion, and trunk extension, each for 5 s. While these positions were held, muscle activation of the thoracic and lumbar erector spinae were measured using surface electromyography. The flexion-relaxation rate was determined by dividing the values for trunk extension by those of complete trunk flexion and by dividing the values for trunk flexion by those of complete trunk flexion. [Results] According to our results, the flexion-relaxation phenomenon was different between healthy young and elderly females with chronic knee osteoarthritis. Specifically, there was a difference in the left thoracic erector spinae muscle, but not in the left and right lumbar erector spinae or right thoracic spinae muscle. [Conclusion] Our study demonstrated that the erector spinae muscle flexion-relaxation phenomenon can be used as a pain evaluation tool in elderly females with chronic knee osteoarthritis.

    In volleyball, blocking is highly correlated with team success. The identification of specific techniques that produce a more successful block would be helpful knowledge for coaches and players. This study compared the traditional, swing, and “chicken wing” blocking techniques in combination with the running step footwork pattern in order to determine which technique enabled athletes to perform a more effective block. High-speed videography (7 cameras, Vicon Motion Analysis System) was used to capture the blocking movements of thirteen female NCAA Division I athletes (age = 19.4 ± 1.19 years, height = 1.82 ± 0.08 m, mass = 70.63 ± 7.96 kg, and years of participation at the collegiate level = 2.23 ± 1.17 years). Each player was familiar with each blocking technique. Reflective markers were placed on the players and in randomized order the players performed 3 blocking trials of each technique. The following dependent variables were assessed: The time it took the athletes to get off the ground and get their hands above (vertically) the net was calculated. The distance the hand reached over the net or hand penetration (displacement between the net and finger in the anterior and vertical planes) was also measured. Lastly, jump height was calculated. Repeated measures ANOVA and post-hoc comparisons were done (α = 0.05). There was no significant difference in the main effect for time to get off the ground (p > 0.05). There was a significant difference in the time to get the hands above the net (p < 0.05). The swing block was best for jump height (p <.001) and hand penetration (p < 0.05). These results can help coaches and players decide which blocking technique will benefit them most as a blocking team and as individual blockers. Key points The swing blocking technique resulted in greater jump heights and increased hand penetration, relative to the traditional and chicken wing blocking techniques. The chicken wing blocking technique resulted in greater jump

    The aim of this study was to determine the differential effects of three commonly used crank lengths (170, 172.5 and 175 mm) on performance measures relevant to female cross-country mountain bike athletes (n = 7) of similar stature. All trials were performed in a single blind and balanced order with a 5- to 7-day period between trials. Both saddle height and fore-aft position to pedal axle distance at a crank angle of 90 degrees was controlled across all trials. The laboratory tests comprised a supra-maximal (peak power-cadence); an isokinetic (50 rpm) test; and a maximal test of aerobic capacity. The time to reach supra-maximal peak power was significantly (P < 0.05) shorter in the 170 mm (2.57 +/- 0.79 s) condition compared to 175 mm (3.29 +/- 0.76 s). This effect represented a mean performance advantage of 27.8% for 170 mm compared to 175 mm. There was no further inter-condition differences between performance outcome measurements derived for the isokinetic (50 rpm) maximum power output, isokinetic (50 rpm) mean power output or indices of endurance performance. The decreased time to peak power with the greater rate of power development in the 170 mm condition suggests a race advantage may be achieved using a shorter crank length than commonly observed. Additionally, there was no impediment to either power output produced at low cadences or indices of endurance performance using the shorter crank length and the advantage of being able to respond quickly to a change in terrain could be of strategic importance to elite athletes.

    Background Hamstring injuries are common in many sports, including track and field. Strains occur in different parts of the hamstring muscle but very little is known about whether common hamstring loading exercises specifically load different hamstring components. The purpose of this study was to investigate muscle activation of different components of the hamstring muscle during common hamstring loading exercises. Methods Twenty elite female track and field athletes were recruited into this study, which had a single-sample, repeated-measures design. Each athlete performed ten hamstring loading exercises, and an electromyogram (EMG) was recorded from the biceps femoris and semitendinosus components of the hamstring. Hamstring EMG during maximal voluntary isometric contraction (MVIC) was used to normalize the mean data across ten repetitions of each exercise. An electrogoniometer synchronized to the EMG was used to determine whether peak EMG activity occurred during muscle-tendon unit lengthening, shortening, or no change in length. Mean EMG values were compared between the two recording sites for each exercise using the Student’s t-test. Results The lunge, dead lift, and kettle swings were low intensity (<50% MVIC) and all showed higher EMG activity for semitendinosus than for biceps femoris. Bridge was low but approaching medium intensity, and the TRX, hamstring bridge, and hamstring curl were all medium intensity exercises (≥50% or <80% MVIC). The Nordic, fitball, and slide leg exercises were all high intensity exercises. Only the fitball exercise showed higher EMG activity in the biceps femoris compared with the semitendinosus. Only lunge and kettle swings showed peak EMG in the muscle-tendon unit lengthening phase and both these exercises involved faster speed. Conclusion Some exercises selectively activated the lateral and medial distal hamstrings. Low, medium, and high intensity exercises were demonstrated. This information enables the clinician, strength

    Background Lower extremity injury commonly affects female soccer athletes. Decreased dynamic balance and hip strength are identified risk factors for lower extremity injury. Little is known about how these factors adapt to a training stimulus in this population. Purpose To retrospectively investigate changes in lower extremity dynamic balance and isometric hip strength in Division I collegiate female soccer athletes after participating in an eight-week strength and conditioning program. Study Design Retrospective, non-experimental cohort study. Methods As part of a standard testing battery, soccer athletes completed athletic performance pre- and post-testing separated by an eight-week off-season conditioning program consisting of overall strength and technical skill development. Testing included lower extremity dynamic balance assessment through the Star Excursion Balance Test (SEBT) and isometric hip abduction and external rotation (ER) strength testing, normalized to limb length and percent body mass, respectively. Athletes rested for one week prior to post-testing. Results Seventeen healthy Division I female soccer athletes (age: 18.8 ± 0.9 years, height: 1.7 ± 0.06 m, mass: 68.0 ± 8.2 kg) completed the protocol. Significant improvements in SEBT composite reach distance were observed in the dominant (DOM) (3.6 ± 4.8%, 95% CI: 1.1 to 6.0) and nondominant (NDOM) (4.8 ± 6.1%, 95% CI: 1.7 to 7.9) limbs. Significant improvements in DOM hip ER strength (2.4 ± 2.3%, 95% CI: 1.3 to 3.6) and DOM SEBT anterior reach (2.1 ± 2.8%, 95% CI: 0.6 to 3.5) were observed. Large effect sizes were observed for DOM and NDOM hip ER strength gains (0.87 – 1.0), while small-moderate effect sizes were noted for the anterior reach direction (0.40 – 0.66). Further, DOM hip ER strength gains were significantly associated with DOM anterior reach performance improvements (r2 = 0.37, p<.01). Conclusion DOM hip ER strength gains appear to be

    [Purpose] The aim of the reported research was to investigate the effects of regular aerobic exercise on cartilage oligomeric matrix protein and oxidative DNA damage in obese, elderly females. [Subjects and Methods] Sixteen class I obese, elderly females, according to World Health Organization criteria, were randomly and equally assigned to a control group (n=8) or an exercise group (n=8). The exercise group participated in exercise sessions of 60 minutes per day, 3 days per week, for a period of 8 weeks. [Results] After aerobic exercise intervention, weight, body mass index, body fat, waist circumference, and DNA damage (Tail moment) were significantly decreased, compared with baseline values. In contrast, serum cartilage oligomeric matrix protein levels were not significantly different among any groups or time-points.

    Exercise causes alterations in redox homeostasis (ARH). Measuring ARH in elite athletes may aid in the identification of training tolerance, fatigued states, and underperformance. To the best of our knowledge, no studies have examined ARH in elite male and female distance runners at sea level. The monitoring of ARH in athletes is hindered by a lack of reliable and repeatable in-the-field testing tools and by the rapid turnaround of results. We examined the effects of various exercise intensities on ARH in healthy (non-over-reached) elite male and female endurance athletes using clinical point-of-care (POC) redox tests, referred to as the free oxygen radical test (FORT) (pro-oxidant) and the free oxygen radical defence (FORD) (antioxidant). Elite male and female endurance athletes (n = 22) completed a discontinuous incremental treadmill protocol at submaximal running speeds and a test to exhaustion. Redox measures were analyzed via blood sampling at rest, warm-up, submaximal exercise, exhaustion, and recovery. FORD was elevated above rest after submaximal and maximal exercise, and recovery (p < 0.05, d = 0.87-1.55), with only maximal exercise and recovery increasing FORT (p < 0.05, d = 0.23-0.32). Overall, a decrease in oxidative stress in response to submaximal and maximal exercise was evident (p < 0.05, d = 0.46). There were no gender differences for ARH (p > 0.05). The velocity at lactate threshold (vLT) correlated with the FORD response at rest, maximal exercise, and recovery (p < 0.05). Using the clinical POC redox test, an absence of oxidative stress after exhaustive exercise is evident in the nonfatigued elite endurance athlete. The blood antioxidant response (FORD) to exercise appears to be related to a key marker of aerobic fitness: vLT.

    The purpose of the study was to analyze changes in physique, body composition, physical fitness, and isokinetic strength in female collegiate taekwondo athletes. The study included 14 subjects, of whom 8 were followed up throughout the study. Anthropometric characteristics included body weight, height, sitting height, circumferences, and bone width. Physical fitness parameters included flexibility, agility, muscle strength, muscular endurance, power, speed, and cardiorespiratory endurance. Peak torque, mean power, and H/Q ratio were analyzed by using Cybex 770. All data were analyzed by using the SAS statistical program. Paired t test was performed, with 0.05 as the significance level. The results indicated significant changes in body weight, and upper arm and flexed upper arm circumferences during the experimental period. Test scores for plate tapping, and sit and reach significantly increased, but that for power decreased. In addition, the peak power of right flexion at 180°/sec was significantly increased, as well as the mean power of right and left flexion, and the H/Q ratio at 180°/sec. PMID:25830145

    This cross-sectional study of adult female athletes assessed whether the apparent loading-related differences in bone structure are primarily associated with the loading type or the muscle performance-related joint moments. Several structural variables at shaft sites of the tibia, radius and humerus, and distal sites of the tibia and radius were measured with peripheral quantitative computed tomography (pQCT) among 113 female national level athletes (representing hurdling, volleyball, soccer, racket-sports and swimming) and their 30 nonathletic referents. For the weight-bearing lower extremities, the loading modalities of the above sports were classified into high-impact (hurdling, volleyball), odd-impact (soccer, racket-sports) and repetitive, nonimpact (swimming) loadings; and for the nonweight-bearing upper extremities into high magnitude (functional weightlifting in hurdling and soccer), impact (volleyball, racket-sports) and repetitive, nonimpact (swimming) loadings. As expected, athletes' bone mass was substantially higher at loaded bone sites compared with the nonathletic referents, but more pertinently to the locomotive perspective, the loading-induced additional bone mass seemed to be used to build mechanically strong and appropriate bone structures. Compared with controls, the weight-bearing bone structures of female athletes (swimmers excluded) were characterized by larger diaphysis, thicker cortices and somewhat denser trabecular bone. The athletes' bones at the nonweight-bearing upper extremity were generally larger in cross-sectional area. The estimated indices of joint moment (muscle force x estimated lever arm) were explained from 29% to 50%, and the loading modalities from 8% to 25%, of the variance in most bone variables (P < 0.05) of the tibia (shaft and distal site). In contrast to the weight-bearing tibia, only the estimated joint moment was positively associated (P < 0.05) with the structural characteristics of the radius and humerus

    In the present study, we examined an expanded model of sport commitment by adding two determinants (perceived costs and perceived competence) and behavioural commitment as a consequence of psychological commitment, as well as identifying psychological commitment as a mediator of relationships between determinants and behavioural commitment. Competitive female gymnasts (N = 304, age 8-18 years) completed relevant measures while coaches rated each gymnast's training behaviours as an indicator of behavioural commitment. Path analysis revealed that the best fitting model was one in which original determinants (enjoyment, involvement opportunities, investments, attractive alternatives) and an added determinant (perceived costs) predicted psychological commitment, in addition to investments and perceived costs directly predicting behavioural commitment. These results provide further, but partial, support for the sport commitment model and also suggest that additional determinants and behavioural consequences be considered in future research.

    Eight whole fresh-frozen cadavers (6 female, 2 male) that were elderly and/or female were laterally impacted using UMTRI's dual-sled side-impact test facility. Cadavers were not excluded on the basis of old age or bone diseases that affect tolerance. A thinly padded, multi-segment impactor was used that independently measured force histories applied to the shoulder, thorax, abdomen, greater trochanter, iliac wing, and femur of each PMHS. Impactor plates were adjusted vertically and laterally toward the subject so that contact with body regions occurred simultaneously and so that each segment contacted the same region on every subject. This configuration minimized the effects of body shape on load sharing between regions. Prior to all tests, cadavers were CT scanned to check for pre-existing skeletal injuries. Cadavers were excluded if they had preexisting rib fractures or had undergone CPR. Cadavers were instrumented with strain gages at the posterolateral, lateral, and anterolateral portions of the struck-side ribs, and chestbands were positioned on the upper and lower thorax. Cadavers were first impacted at 3 m/s. If two or fewer rib fractures occurred, as determined using strain gage data and a post-test CT scan, a second impact was performed at 6 m/s on the contralateral side of the body. Five of the eight 3-m/s tests produced AIS 3+ level injuries. All three of the 6-m/s tests produced AIS 3+ injury. Response corridors were developed for each body region using the Maltese alignment method with impulse-momentum normalization. Corridors describing upper and lower thorax deflection were generated from chestband data. An injury risk curve developed from the deflections associated with AIS 3+ injury associates a 50% probability of AIS 3+ rib fracture with 25.6% half-thorax deflection for the population used in this study.

    Objective To determine bone mineral density (BMD) and the associations among BMD, menstrual history, disordered eating (DE), training history, intentional weight loss (IWL) and rib pain for the first time in female lightweight rowers. Setting 9 lightweight rowing clubs, UK. Participants 29 Caucasian female lightweight rowers volunteered. 21 (12 active, 9 retired) completed the study. Inclusion criteria: female lightweight rowers aged over 18 years. Exclusion criteria: participants with a history of bone disease, used medications known to influence BMD or if they were pregnant, lactating or postmenopausal. Main outcome measures Dual-energy X-ray absorptiometry measured total body (TB) composition and BMD at the spine, femoral neck (FN), radius and TB. DE, oligomenorrhoea/amenorrhoea years; rib pain and training history. Results DE was reported in six of the rowers. The active with DE started rowing younger (p<0.05) than those without, and their amount of IWL was associated with Eating Attitudes Test-26 score (p<0.05). Some participants reported a history of oligomenorrhoea/amenorrhoea 17 (76%) and/or rib pain 7 (32%) with those with rib pain having lower spine and TB Z-scores (p<0.05) than those without. Those with oligomenorrhoea/amenorrhoea had lower spine Z-scores (p<0.01) than those without. Twelve participants had low BMD; three at spine; one at FN; and eight at radius. Thirteen per cent of mean total training hours (18.6±9.1 h/week) were spent strength training (2.4±2.2 h/week). Conclusions Upper body exercises incorporating multidimensional high peak bone strain were not reported and may need to be considered in their strength training to improve radial BMD. Results suggest IWL and high-level training at a young age increases the likelihood of DE and there may be a lack of quality nutritional support for these athletes. Thus, multidisciplinary sport science support should be offered at a young age and perhaps also to consider changing the weight rules

    In 2002, Tennis Australia commissioned a report into the experiences of elite female past players on leaving the professional tennis circuit. Australian players who were in the top 800 of the Women's Tennis Association (WTA) end of year rankings and who had left the professional circuit within the previous 15 years were asked by mail to respond to a questionnaire. The questionnaire asked players to describe their feelings about leaving the tour during the time leading up to leaving the tour to two years after retirement. The main findings of the study suggested that those who planned to leave the tour found the transition process easy, whereas those who did not plan to leave the tour found the process difficult. Most players (66%) did not regret leaving the tour, and, although the remaining players responded that they regretted leaving, none attempted a comeback. Tennis Australia has implemented strategies to assist current players on the professional tour based on the results of this study. PMID:16632584

    [Purpose] This study is designed to compare the effects of abdominal drawing-in exercise and myofascial release on pain, flexibility, and balance of elderly females. [Subjects and Methods] Forty elderly females aged 65 or older who had complained of low back pain for three months or longer were selected as the subjects. They were randomly and equally assigned to either an abdominal drawing-in group or a myofascial release group. The subjects conducted exercise three times per week, 40 minutes each time, for eight weeks. As evaluation tools, visual analogue scale for pain, remodified schober test for flexibility, and upright posture with eye opening on hard platform, upright posture with eye closing on hard platform, upright posture with eye opening on soft platform, upright posture with eye closing on soft platform using tetrax for balance were used. [Results] The abdominal drawing-in exercise group saw significant difference in pain and balance after the exercise compared to before the exercise. The myofascial release group saw significant difference in pain and flexibility after exercise compared to before the exercise. [Conclusion] The above study showed that abdominal drawing-in exercise affected elderly females regarding pain and balance and myofascial release influenced their pain and flexibility. PMID:27821941

Assessment of fatigue and recovery in male and female athletes after 6 days of intensified strength training. J Strength Cond Res 30(12): 3412-3427, 2016-This study aimed to analyze changes of neuromuscular, physiological, and perceptual markers for routine assessment of fatigue and recovery in high-resistance strength training. Fourteen male and 9 female athletes participated in a 6-day intensified strength training microcycle (STM) designed to purposefully overreach. Maximal dynamic strength (estimated 1 repetition maximum [1RMest]; criterion measure of fatigue and recovery); maximal voluntary isometric strength (MVIC); countermovement jump (CMJ) height; multiple rebound jump (MRJ) height; jump efficiency (reactive strength index, RSI); muscle contractile properties using tensiomyography including muscle displacement (Dm), delay time (Td), contraction time (Tc), and contraction velocity (V90); serum concentration of creatine kinase (CK); perceived muscle soreness (delayed-onset muscle soreness, DOMS) and perceived recovery (physical performance capability, PPC); and stress (MS) were measured before and after the STM and after 3 days of recovery. After completing the STM, there were significant (p ≤ 0.05) performance decreases in 1RMest (%[INCREMENT] ± 90% confidence limits, ES = effect size; -7.5 ± 3.5, ES = -0.21), MVIC (-8.2 ± 4.9, ES = -0.24), CMJ (-6.4 ± 2.1, ES = -0.34), MRJ (-10.5 ± 3.3, ES = -0.66), and RSI (-11.2 ± 3.8, ES = -0.73), as well as significantly reduced muscle contractile properties (Dm, -14.5 ± 5.3, ES = -0.60; V90, -15.5 ± 4.9, ES = -0.62). After days of recovery, a significant return to baseline values could be observed in 1RMest (4.3 ± 2.8, ES = 0.12), CMJ (5.2 ± 2.2, ES = 0.28), and MRJ (4.9 ± 3.8, ES = 0.32), whereas RSI (-7.9 ± 4.5, ES = -0.50), Dm (-14.7 ± 4.8, ES = -0.61), and V90 (-15.3 ± 4.7, ES = -0.66) remained

    Background: Ginger rhizomes (rich in gingerols, shogaols, paradols and zingerone) have been used in Asia for the treatment of asthma, diabetes, and pain, and have shown potent anti-inflammatory attributes. Common spices such as Cinnamon (including cinnamic aldehyde and cinnamyl aldehydeis) are used in food and many studies have focused on its anti-inflammatory components. Intense exercise can result in an inflammatory response to cell damage and also muscle soreness. The efficacy of dietary ginger and cinnamon as anti-inflammatory agents and their effectiveness in reducing muscle soreness has been investigated in limited studies on humans. Therefore, we have studied the effects of dietary ginger and cinnamon on inflammation and muscle soreness in Iranian female taekwondo players. Methods: Sixty healthy, trained women, aged 13-25 years, were enrolled in the six-week investigation and randomly categorized into three groups (cinnamon, ginger or placebo) and received 3 g of ginger, cinnamon or placebo powder each day, depending on the group they belonged to. The IL-6 level and Likert Scale of Muscle Soreness were evaluated at the beginning and the end of the study and compared among the groups. Results: Forty-nine of the participants completed the six-week intervention. There were no significant changes in the IL-6 cinnamon and ginger group when compared with the placebo group, whereas, there was a significant fall in muscle soreness in the cinnamon group and placebo (P < 0.1) and ginger group and placebo (P < 0.01). Conclusions: Administration of ginger and cinnamon in athlete women for six weeks did not show any significant change in the IL-6 level, but showed a decrease in muscle soreness in the cinnamon and ginger groups.

    It has been suggested that activities of daily living could contribute to the occurrence of ACL injury in females. Currently, no studies have focused on the lower extremity behavior of a non-athletic population to compare or understand the lower extremity adeptness towards daily movements that mimic athletic tasks. Our hypothesis was that increased knee valgus angles would occur during the late follicular phase of the menstrual cycle accompanied by different onset timing of the gluteus medius muscle. In a controlled laboratory study, 23 non-athletic collegiate females participated and 15 subjects comprised the final sample for statistical analysis. Subjects performed a single leg drop landing maneuver while 3-D knee kinematics and gluteus medius muscle onset timing were assessed throughout three distinct phases of the menstrual cycle, confirmed by blood hormone analysis. In general, knee valgus angles were significantly less in the luteal phase compared to both follicular phases (p<0.005), while differences were not observed for gluteus medius onset timing (p=0.936). As a decreased knee joint valgus angle was observed during the luteal phase, it was hypothesized that the hormone progesterone could significantly influence knee kinematics during a dynamic task. However, such influence was not observed for gluteus medius EMG onset timing as a significant correlation between gluteus medius onset timing and knee valgus angle could not be determined.

    The use of caffeine containing energy drinks has dramatically increased in the last few years, especially in the sport context because of its reported ergogenic effect. The ingestion of low to moderate doses of caffeinated energy drinks has been associated with adverse side effects such as insomnia or increased nervousness. The aim of the present study was to assess psycho-physiological changes and the prevalence of side effects resulting from the ingestion of 3 mg caffeine/kg body mass in the form of an energy drink. In a double-blind and placebo controlled experimental design, ninety experienced and low-caffeine-consuming athletes (fifty-three male and thirty-seven female) in two different sessions were provided with an energy drink that contained 3 mg/kg of caffeine or the same decaffeinated energy drink (placebo; 0 mg/kg). At 60 min after the ingestion of the energy drink, participants completed a training session. The effects of ingestion of these beverages on psycho-physiological variables during exercise and the rate of adverse side effects were measured using questionnaires. The caffeinated energy drink increased self-perceived muscle power during exercise compared with the placebo beverage (6·41 (sd 1·7) v. 5·66 (sd 1·51); P= 0·001). Moreover, the energy drink produced a higher prevalence of side effects such as insomnia (31·2 v. 10·4 %; P< 0·001), nervousness (13·2 v. 0 %; P= 0·002) and activeness (16·9 v. 3·9 %; P= 0·007) than the placebo energy drink. There were no sex differences in the incidence of side effects (P>0·05). The ingestion of an energy drink with 3 mg/kg of caffeine increased the prevalence of side effects. The presence of these side effects was similar between male and female participants.

    This study aimed to evaluate the effectiveness of a whole-body vibration training program to improve neuromuscular performance in young elite female athletes. Twenty-three women basketball players (14-18 years old) were randomly assigned to a control group (CG, n = 11) or to a whole-body vibration group (WBVG, n = 12). During the study period, both groups continued their usual training program, but the WBVG also underwent a 15-week vibration training program. We analyzed the countermovement jump test (CMJ), the 1-leg hop test for the right leg and for the left leg, and the single-limb standing balance for both legs and with eyes open and closed at 3 time points: before training (T1), after an 8-week training period (T2), and after a further 7-week training period (T3). Compared with the CG, CMJ increased significantly in the WBVG from T1 to T2 (6.47%, p < 0.001), T1 to T3 (10.07%, p = 0.005), and T2 to T3 (3.38%, p < 0.001). One-leg hop test for the right and left legs also showed significantly higher values in WBVG from T1 to T2 (10.12%, p < 0.001 and 9.63%, p = 0.002, respectively) and T1 to T3 (14.17%, p = 0.001 and 15.17%, p = 0.004, respectively). Lateral deviation of the center of pressure in the closed eyes test decreased significantly in WBVG for both right and left leg, from T1 to T2 (-22.20%, p = 0.043 and -34.77%, p < 0.001, respectively) and from T1 to T3 (-33.14%, p = 0.027 and -33.58%, p = 0.043, respectively) compared with the CG. In conclusion, our results show that a 15-week whole-body vibration training program improves explosive strength and postural stability in adolescent female basketball players.

    Bone marrow insulin sensitivity may be an important factor for bone health in addition to bone mineral density especially in insulin resistant conditions. First we aimed to study if prenatal maternal obesity plays a role in determining bone marrow insulin sensitivity in elderly female offspring. Secondly we studied if a four-month individualized resistance training intervention increases bone marrow insulin sensitivity in elderly female offspring and whether this possible positive outcome is regulated by the offspring’s mother’s obesity status. 37 frail elderly females (mean age 71.9 ± 3.1 years) of which 20 were offspring of lean/normal-weight mothers (OLM, maternal BMI ≤ 26.3 kg/m2) and 17 were offspring of obese/overweight mothers (OOM, maternal BMI ≥ 28.1 kg/m2) were studied before and after a four-month individualized resistance training intervention. Nine age- and sex-matched non-frail controls (maternal BMI ≤ 26.3 kg/m2) were studied at baseline. Femoral bone marrow (FBM) and vertebral bone marrow (VBM) insulin sensitivity were measured using [18F]fluoro-2-deoxy-D-glucose positron emission tomography with computer tomography under hyperinsulinemic euglycemic clamp. We found that bone marrow insulin sensitivity was not related to maternal obesity status but FBM insulin sensitivity correlated with whole body insulin sensitivity (R = 0.487, p = 0.001). A four-month resistance training intervention increased FBM insulin sensitivity by 47% (p = 0.006) only in OOM, while VBM insulin sensitivity remained unchanged regardless of the maternal obesity status. In conclusion, FBM and VBM glucose metabolism reacts differently to a four-month resistance training intervention in elderly women according to their maternal obesity status.

    Effects of nine social life indicators on age-adjusted and age-specific annual suicide mortality of male and female Japanese population in the years 1953-96 were investigated by multiple regression analysis on time series data. Unemployment rate was significantly related to the age-adjusted mortality in both males and females. Also, female labour force participation was positively related to the male mortality; persons and 65 and above was inversely related to the male mortality. Results on the age-specific mortality indicated that: during the 44 yr, (1) unemployment significantly related with the mortality of young, middle-aged and elderly males and young females; (2) female labour force participation significantly related with the mortality of young and elderly males and young females; aged population significantly related with the mortality of middle-aged and elderly males; (4) young population significantly related with the mortality of young and middle-aged males and females; (5) divorce significantly related with the mortality of middle-aged and elderly males and young males and females; (6) persons employed in primary industries significantly related with the mortality in middle-aged males and young males and females; and (7) population density significantly related with the mortality of middle-aged males and young females.

    The purpose of the study was to determine the effect of 8 weeks pre-season training on body composition, physical fitness, anaerobic capacity, and isokinetic strength in collegiate taekwondo athletes. Thirty-four collegiate athletes (male: 22, female: 12) participated. Body composition, bone mineral density, physical fitness, anaerobic capacity, and isokinetic muscle strength were tested. After statistical analysis was performed the results indicated that there were significant decreases in body weight, percent body fat, and fat tissue after 8 weeks of pre-season training. Bone mineral density increased significantly only in males. There were significant improvements in the 50 m shuttle run and 20 m multistage endurance run in both males and females. The sit & reach test and standing long jump were not significantly changed after 8 weeks. Relative peak power and anaerobic capacity were significantly improved in males. Significant increases in angular velocity were observed for knee extension at both % BW 60°/sec and 180°/sec in both males and females. A significant increase in angular velocity was seen for right knee flexion at % BW 60°/sec for males, but it decreased at % BW 180°/sec for both males and females. In conclusion, this study suggests that 8 weeks of pre-season training has a positive effect on body composition, physical fitness, anaerobic capacity, isokinetic muscular strength, and endurance. Nevertheless, an exercise approach with the goal of increasing lean tissue, and improving power in knee flexors and flexibility of athletes, should be included in the training program. PMID:25960983

After statistical analysis was performed the results indicated that there were significant decreases in body weight, percent body fat, and fat tissue after 8 weeks of pre-season training. Bone mineral density increased significantly only in males. There were significant improvements in the 50 m shuttle run and 20 m multistage endurance run in both males and females. The sit & reach test and standing long jump were not significantly changed after 8 weeks. Relative peak power and anaerobic capacity were significantly improved in males. Significant increases in angular velocity were observed for knee extension at both % BW 60°/sec and 180°/sec in both males and females. A significant increase in angular velocity was seen for right knee flexion at % BW 60°/sec for males, but it decreased at % BW 180°/sec for both males and females. In conclusion, this study suggests that 8 weeks of pre-season training has a positive effect on body composition, physical fitness, anaerobic capacity, isokinetic muscular strength, and endurance. Nevertheless, an exercise approach with the goal of increasing lean tissue, and improving power in knee flexors and flexibility of athletes, should be included in the training program.

    We investigated the effects of progressively increased training load and overtraining on resting and intrinsic heart rate (IHR) and cardiac autonomic modulation (CAM), and their relationships to performance variables. Nine athletes (ETG) increased training volume at 70-90% of maximal oxygen uptake (VO2max) by 130% (p<0.01) and training volume at <70% VO2max by 100% (p < 0.01) during 6-9 weeks. The corresponding increases in six female control athletes (CG) were 5 and 10%. Pharmacological blocking through atropine and propranolol and the Rosenblueth and Simeone model were used to calculate the sympathovagal balance index (Abal) and to measure IHR. The results were analysed using two-way analysis of variance. VO2max, IHR and Abal did not change. Resting heart rate had a tendency to decrease in the ETG and increase in the CG during the training period (interaction p < 0.01). Five ETG athletes demonstrated overtraining state (OA subgroup). Their VO2max (mean+/-SEM) decreased from 53.0+/-2.2 ml x kg(-1) x min(-1) to 50.2+/-2.3 ml x kg(-1) x min(-1) (p < 0.01), but no changes in resting HR, IHR and Abal were found. A significant correlation between the baseline values of VO2max and the parasympathetic activity index was found (r=-0.59, p < 0.05). In conclusion, progressively increased training load and overtraining did not induce significant changes in intrinsic heart rate or cardiac autonomic modulation in female endurance athletes. Resting heart rate rather decreased with heavy endurance training and overtraining. High maximal oxygen uptake was correlated with high cardiac parasympathetic modulation.

    Iron is an important mineral necessary for many biologic pathways. Different levels of deficiency can occur in the athlete, resulting in symptoms that range from none to severe fatigue. Iron deficiency without anemia may adversely affect athletic performance. Causes of iron deficiency include poor intake, menstrual losses, gastrointestinal and genitourinary losses due to exercise-induced ischemia or organ movement, foot strike hemolysis, thermohemolysis, and sweat losses. A higher incidence of deficiency occurs in female athletes compared with males.

    OBJECTIVE: To perform genetic sex typing during the Barcelona Olympic Games using polymerase chain reaction (PCR) amplification of Y chromosome specific sequences. METHODS: The assay consisted of the amplification of a specific sequence corresponding to the repeat DYZ1 element from buccal smears samples of 2406 female competitors. Positive samples were reanalysed for the presence of another Y chromosome specific gene, SRY. RESULTS: The expression of these two elements did not always correlate; six samples were found where the presence of DYZ1 but not SRY was detected. This presence of DYZ1 sequence in female athletes is higher than in unselected females, where no DYZ1 amplification was observed in any of the 1629 samples analysed. CONCLUSIONS: Amplification of DYZ1 repeat should not be used as the only index for determining genetic sex, at least in sporting events. Images Figure 2 Figure 4 PMID:9015592

    Kar, Julia; Quesada, Peter M

    2013-02-01

    The central goal of this study was to contribute to the advancements being made in determining the underlying causes of anterior cruciate ligament (ACL) injuries. ACL injuries are frequently incurred by recreational and professional young female athletes during non-contact impact activities in sports like volleyball and basketball. This musculoskeletal-neuromuscular study investigated stop-jumps and factors related to ACL injury like knee valgus and internal-external moment loads, knee anterior-posterior (AP) shear forces, ACL strains and internal forces. Motion capture data was obtained from the landing phase of stop-jumps performed by eleven young recreational female athletes and electromyography (EMG) data collected from quadriceps, hamstring and gastrocnimius muscles which were then compared to numerically estimated activations. Numerical simulation tools used were Inverse Kinematics, Computed Muscle Control and Forward Dynamics and the knee modeled as a six degree of freedom joint. Results showed averaged peak strains of 12.2 ± 4.1% in the right and 11.9 ± 3.0% in the left ACL. Averaged peak knee AP shear forces were 482.3 ± 65.7 N for the right and 430.0 ± 52.4 N for the left knees, approximately equal to 0.7-0.8 times body weight across both knees. A lack of symmetry was observed between the knees for valgus angles (p < 0.04), valgus moments (p < 0.001) and muscle activations (p < 0.001), all of which can be detrimental to ACL stability during impact activities. Comparisons between recorded EMG data and estimated muscle activations show the relation between electrical signal and muscle depolarization. In summary, this study outlines a musculoskeletal simulation approach that provides numerical estimations for a number of variables associated with ACL injuries in female athletes performing stop-jumps.

    Fibrous dysplasia (FD) is an uncommon skeletal disorder in which normal bone is replaced by abnormal fibro-osseous tissue. Mainly, FD is found in children, and by adulthood it usually becomes quiescent. Our case showed FD of more than 14-year duration in the left maxilla. Our evaluation was that growth ceased in adulthood and had achieved the static stage. Because FD cases in elderly patients are rarely reported, we hereby present a monostotic FD case in a 65-year-old female. We presented sequential radiographic images and scintigraphic images of this case, and combined them with a literature review that emphasized the progression of the disease. PMID:28035304

    Female athletes are more prone to anterior cruciate ligament (ACL) injury than their male counterparts, presumably because of anatomical, hormonal, and neuromuscular differences. Of these three, only the neuromuscular component can be modified by preventive exercise. We aimed to evaluate the effect of a neuromuscular protocol on the prevention of ACL injury by performing meta-analysis, and to identify essential factors by subgroup analysis. An extensive literature review was conducted to identify relevant studies, and eventually, only seven randomized controlled trials or prospective cohort studies were included in the analysis. The odds ratios (OR) and the confidence interval (CI) for the overall effects of training and of potentially contributory factors were estimated. The OR and the 95% CI for the overall effect of the preventive training were 0.40 and [0.27, 0.60], respectively. Subgroup analysis revealed that an age under 18, soccer rather than handball, pre- and in-season training rather than either pre- or in-season training, and the plyometrics and strengthening components rather than balancing were significant. Meta-analysis showed that pre- and in-season neuromuscular training with an emphasis on plyometrics and strengthening exercises was effective at preventing ACL injury in female athletes, especially in those under 18 years of age. Further study is required to develop a relevant training program protocol of appropriate intensity.

    In nonhuman primates, anxiety levels are typically assessed by observing social hierarchies or behavior in an intruder task. As measures of anxiety might influence performance on a particular cognitive task, it is important to analyze these measures in the same room as used for the cognitive task. As we use a playroom for the spatial maze test, we classified elderly female rhesus macaques (Macaca mulatta) monkeys, as bold or reserved monkeys based on the time spent in specific areas of this room. Based on their exploratory behavior in the playroom, bold monkeys were defined as animals that spent 20% more time in the unprotected areas of the room than in the protected areas, whereas reserved monkeys spent a comparable amount of time in both areas. MRI analyses showed that reserved monkeys had a smaller amygdala compared to bold monkeys but there were no group differences in hippocampal volumes. In addition, the amount of time spent in the corners of the room was negatively correlated with the right amygdala as well as the total amygdala size. Finally, reserved monkeys showed a lower phMRI response to the muscarinic receptor antagonist scopolamine compared to the bold monkeys. Thus, in elderly female nonhuman primates measures of anxiety are associated with structural amygdala differences and hippocampal muscarinic receptor function.

    Objectives The purpose of this study was to evaluate the quality of life (QOL) in postmenopausal members and non-members of the elderly support association in Borujen city, Iran. Methods This study was a cross-sectional descriptive study being applied to the participants were postmenopausal women of over 55 years. Thus, 40 postmenopausal members of the elderly support association of Borujen city and 40 non-members were randomly selected. The 36 item short-form health survey (SF-36), with the 4 psychological, social, physical-movement, and environmental domains, was completed. Data were analyzed using SPSS software. Results The mean total score of QOL of member of the association was significantly greater than non-members. Student's t-test showed a significant relationship between QOL and membership of the association (P < 0.05). One-way analysis of variance (ANOVA) showed that the mean QOL of postmenopausal women, according to membership and marital status (P < 0.01), housing (P < 0.01), and underlying disease (P < 0.01), was statistically significant. Conclusions According to the results, supportive measures, such as increasing the participation of the elderly in public life through proper preparations to join them and membership in peer groups such as support associations and non-governmental organizations (NGOs) can be greatly effective in improving QOL. The results showed that the QOL of the participants was at a moderate level and membership in support associations for the elderly was effected on the QOL in postmenopausal women. Moreover, considering the importance of the elderly in the community. PMID:28119895

    Exercise-related menstrual dysfunction (ExMD) is associated with low energy availability (EA), decreased bone mineral density (BMD), and increased risk of musculoskeletal injury. We investigated whether a 6-month carbohydrate-protein (CHO-PRO) supplement (360 kcal/day, 54 g CHO/day, 20 g PRO/day) intervention would improve energy status and musculoskeletal health and restore menses in female athletes (n = 8) with ExMD. At pre/post-intervention, reproductive and thyroid hormones, bone health (BMD, bone mineral content, bone markers), muscle strength/power and protein metabolism markers, profile of mood state (POMS), and energy intake (EI)/energy expenditure (7 day food/activity records) were measured. Eumenorrheic athlete controls with normal menses (Eumen); n = 10) were measured at baseline. Multiple linear regressions were used to evaluate differences between groups and pre/post-intervention blocking on participants. Improvements in EI (+382 kcal/day; p = 0.12), EA (+417 kcal/day; p = 0.17) and energy balance (EB; +466 kcal/day; p = 0.14) were observed with the intervention but were not statistically significant. ExMD resumed menses (2.6 ± 2.2-months to first menses; 3.5 ± 1.9 cycles); one remaining anovulatory with menses. Female athletes with ExMD for >8 months took longer to resume menses/ovulation and had lower BMD (low spine (ExMD = 3; Eumen = 1); low hip (ExMD = 2)) than those with ExMD for <8 months; for 2 ExMD the intervention improved spinal BMD. POMS fatigue scores were 15% lower in ExMD vs. Eumen (p = 0.17); POMS depression scores improved by 8% in ExMD (p = 0.12). EI, EA, and EB were similar between groups, but the intervention (+360 kcal/day) improved energy status enough to reverse ExMD despite no statistically significant changes in EI. Similar baseline EA and EB between groups suggests that some ExMD athletes are more sensitive to EA and EB fluctuations.

  18. Effects of jump and balance training on knee kinematics and electromyography of female basketball athletes during a single limb drop landing: pre-post intervention study

    PubMed Central

    2011-01-01

    Background Some research studies have investigated the effects of anterior cruciate ligament (ACL) injury prevention programs on knee kinematics during landing tasks; however the results were different among the studies. Even though tibial rotation is usually observed at the time of ACL injury, the effects of training programs for knee kinematics in the horizontal plane have not yet been analyzed. The purpose of this study was to determine the effects of a jump and balance training program on knee kinematics including tibial rotation as well as on electromyography of the quadriceps and hamstrings in female athletes. Methods Eight female basketball athletes participated in the experiment. All subjects performed a single limb landing at three different times: the initial test, five weeks later, and one week after completing training. The jump and balance training program lasted for five weeks. Knee kinematics and simultaneous electromyography of the rectus femoris and Hamstrings before training were compared with those measured after completing the training program. Results After training, regarding the position of the knee at foot contact, the knee flexion angle for the Post-training trial (mean (SE): 24.4 (2.1) deg) was significantly larger than that for the Pre-training trial (19.3 (2.5) deg) (p < 0.01). The absolute change during landing in knee flexion for the Post-training trial (40.2 (1.9) deg) was significantly larger than that for the Pre-training trial (34.3 (2.5) deg) (p < 0.001). Tibial rotation and the knee varus/valgus angle were not significantly different after training. A significant increase was also found in the activity of the hamstrings 50 ms before foot contact (p < 0.05). Conclusions The jump and balance training program successfully increased knee flexion and hamstring activity of female athletes during landing, and has the possibility of producing partial effects to avoid the characteristic knee position observed in ACL injury, thereby

    Abstract Frailty is a geriatric syndrome associated with adiposity. Zinc alpha2-glycoprotein (ZAG), a novel adipokine, is a modulator of body fat mass and positively correlates with age. This observational study aims to investigate the relationship between plasma ZAG levels and frailty in the elderly. We enrolled 189 elder participants from a hospital-based comprehensive geriatric assessment program in Taiwan from January 2007 to June 2008. The demographic data, body weight, body mass index, appendicular skeletal muscle mass index (ASMI), body fat mass percentage, metabolic and inflammatory parameters including plasma tumor-necrosis factor alpha, C-reactive protein and ZAG levels, were assessed. The frailty score was assessed by Fried Frailty Index. The mean age of all participants (91 [48.1%] men and 98 [51.9%] women) was 77.19 ± 6.12 years. Judged by the FFI score, 46 (24.34%) elders were robust, 106 (56.08%) were pre-frail, and 37 (19.58%) were frail. Older men showed greater ASMI and lower fat mass percentage in comparison to older women (P < 0.0001). The log-transformed mean plasma ZAG (μg/mL) level of overall was 1.82 ± 0.11, and it was higher in men than in women (1.85 ± 0.12 vs 1.79 ± 0.1, P = 0.0006). Plasma ZAG levels were different among the robust, pre-frail and frail subgroups (1.78 ± 0.09, 1.83 ± 0.12, 1.83 ± 1.10, respectively, P = 0.028), and the differences were more significant in woman elders (P = 0.005). Further multiple linear regression analysis showed plasma ZAG levels positively correlated with frailty severity in women (P for trend = 0.0435). Plasma ZAG levels positively correlated with frailty severity in woman elders. The difference between sexes suggests certain sex-specific mechanisms may exist to affect the association between plasma ZAG levels and frailty. PMID:27583927

    Background Although functional tests including the single leg hop (SLH), triple hop (TH), cross over hop (COH) for distance, and the tuck jump assessment (TJA) are used for return to play (RTP) criteria for post anterior cruciate ligament (ACL) injury, sport-specific baseline measurements are limited. Purpose The purpose of this study was to examine differences in SLH, TH, and COH distance and limb symmetry index (LSI), as well as total scores, number of jumps, and individual flaws of the TJA in 97 injury-free Division I (DI) collegiate female student athletes participating in ACL injury prone vs. non ACL injury prone sports. The hypothesis was that significant mean differences and asymmetries (LSI) would exist between the two groups in SLH, TH, COH and TJA. Study Design Cross sectional. Methods Due to research suggesting inherent ACL injury risk associated with specific sport involvement, participants were grouped into high (HR, n=57) and low (LR, n=40) ACL injury risk based on participating in a sport with high or low ACL injury rates. The HR group was composed of athletes participating in soccer, basketball, and volleyball, while the LR group athletes participated in diving, cross country, and track and field. Participants performed all standard functional tests (SFT) and side-to-side differences for each participant as well as between group differences were assessed for the hop tests. The LSI, a ratio frequently used to gauge athletes’ readiness for RTP post injury, was also assessed for between group differences. The TJA was compared between the groups on individual flaws, overall scores, and number of jumps performed. Results No between group differences for hop distances were found, with medium to large effect sizes for SLH, TH, and COH. The HR group had a higher TJA score, number of jumps, and higher proportion of the flaw of ‘foot placement not shoulder width apart’. Conclusion Although most SFT's showed no significant differences between athlete

    Tetralogy of Fallot is the most common cyanotic congenital heart disease in children. It is usually detected in early infancy due to symptoms related to cyanosis and right to left shunting of blood through a large ventricular septal defect. Uncorrected it is associated to a very poor prognosis, with only 3% of adults surviving by age 40 years of age. The combination of tetralogy of Fallot with agenesis of the pulmonary arteries is a rare congenital condition with some reports describing it in 2-3% of patients with Tetralogy of Fallot (ToF). Some rare reports of prolonged survival in patients with uncorrected ToF have been described in the medical literature with some patients living until late adulthood. Here we describe the rare presentation of an elderly female with uncorrected ToF and agenesis of the left pulmonary artery.

    Objective: To determine the numbers needed to treat (NNT) and relative risk reduction (RRR) associated with neuromuscular training programs aimed at preventing noncontact anterior cruciate ligament (ACL) injuries in female athletes. Data Sources: We searched PubMed, MEDLINE, SPORT Discus, CINAHL, and Web of Science from 1966 through 2005 using the terms knee, injury, anterior cruciate ligament, ACL, prevention, plyometric, and neuromuscular training. Study Selection: Selected articles were from peer-reviewed journals written in English that described original research studies comparing neuromuscular training programs with control programs to determine the number of noncontact ACL injuries per event exposure or hours of playing time. Five studies met the inclusion criteria and were independently rated by 3 reviewers using the Physiotherapy Evidence Database (PEDro) scale. Consensus PEDro scores ranged from 4 to 7 out of 10. Data Extraction: We used numbers of subjects, ACL injuries, and injury exposure rates to calculate NNT and RRR for each study. The NNT calculations from all studies were based on the number of players across 1 competitive season and were described as NNT benefit or NNT harm. Data Synthesis: All 5 studies demonstrated a prophylactic effect due to the neuromuscular training programs. The pooled NNT estimates showed that 89 individuals (95% confidence interval: 66 to 136) would need to participate in the prophylactic training program to prevent 1 ACL injury over the course of 1 competitive season. Pooled RRR was 70% (95% confidence interval: 54% to 80%) among individuals who participated in the intervention program. One high-quality randomized control trial and 4 medium-quality prospective cohort studies showed mostly consistent findings. Thus, a Strength of Recommendation Taxonomy level of evidence of 1 with a grade B recommendation supports the use of neuromuscular training programs in the prevention of noncontact ACL injuries in female athletes

    The objective of this study was to determine the impact of iron depletion without anemia on performance in a sample of female collegiate rowers at the beginning of a training season (August 2008, January 2009, and September 2009). One hundred sixty-five female collegiate rowers from 5 colleges and universities in central New York State participated in a screening of iron status. Blood hemoglobin (Hgb), serum ferritin (sFer), and soluble transferrin receptor were measured to determine prevalence of iron depletion and anemia. Rowers' habitual moderate and vigorous physical activity, as well as their best time to complete a 2-km simulated race during the previous 3 months, were self-reported. Sixteen rowers (10%) were identified as anemic (Hgb <12.0 g/dl). Using a sFer cutoff of <20.0 μg/L, 30% (n = 44) of the nonanemic rowers were identified as iron depleted without anemia and reported 2-km times ~21 s slower (p < .004) than rowers with normal iron status. Given the high prevalence of iron depletion reported in this and other studies, screening for low iron stores at the start of a training program in female athletes involved in an endurance sport may be clinically useful. In this study, iron-depleted rowers (sFer <20-25 μg/L) reported a decrease in performance time compared with those with normal iron stores.

    Hip fracture is a kind of osteoporotic fractures in elderly patients. Its important monitoring indicator is to measure bone mineral density (BMD) using DXA. The stress characteristics and material distribution in different parts of the bones can be well simulated by three-dimensional finite element analysis. Our previous studies have demonstrated a linear positive correlation between clinical BMD and the density of three-dimensional finite element model of the femur. However, the correlation between the density variation between intertrochanteric region and collum femoris region of the model and the fracture site has not been studied yet. The present study intends to investigate whether the regional difference in the density of three-dimensional finite element model of the femur can be used to predict hip fracture site in elderly females. The CT data of both hip joints were collected from 16 cases of elderly female patients with hip fractures. Mimics 15.01 software was used to reconstruct the model of proximal femur on the healthy side. Ten kinds of material properties were assigned. In Abaqus 6.12 software, the collum femoris region and intertrochanteric region were, respectively, drawn for calculating the corresponding regional density of the model, followed by prediction of hip fracture site and final comparison with factual fracture site. The intertrochanteric region/collum femoris region density was [(1.20 ± 0.02) × 10(6)] on the fracture site and [(1.22 ± 0.03) × 10(6)] on the non-fracture site, and the difference was statistically significant (P = 0.03). Among 16 established models of proximal femur on the healthy side, 14 models were consistent with the actual fracture sites, one model was inconsistent, and one model was unpredictable, with the coincidence rate of 87.5 %. The intertrochanteric region or collum femoris region with lower BMD is more prone to hip fracture of the type on the corresponding site.

    Background: Sleep is considered as one of the most important factors, directly influencing mental and physical health components. In the last decade, low sleep quality - i.e. poor sleep - has become one of the major problems of the individuals, especially in middle-aged women. Low quality sleep also directly influences memory, functional components, nutrition, and mood. Objectives: This study aims to detect the effect of selected aerobic exercises on sleep quality in non-athlete middle-aged women. Materials and Methods: Fifteen non-athlete middle-aged women participated in this study, all of them suffered from insomnia. Pittsburgh questionnaire was used for determining sleep quality in this sample. Four indices including sleep duration, sleep disturbance, sleep latency, and sleep efficiency have been investigated through this. The period of exercises included eight weeks, three one-hour sessions each week. The sample group was trained during eight weeks through performance of selected aerobic exercises including three groups: sequential movements equip mental movement and movements on the pad. The selected protocol included performance of exercises: 10 minutes for warm up, 10 minutes for sequential movements, 20 minutes for movements by using equipment, 15 minutes for movements performed on the pad, and 5 minutes for cooling down. The exercises during the first four weeks have been presented with 60% increase of the heart rate, and 75% increase during the second four weeks. The sample group was provided with Pittsburgh questionnaire at the beginning of the exercises and the end of each week. The information of each person was registered. Results: The results showed that the mean of sleep duration, sleep disturbance, sleep latency, and sleep efficiency indices significantly reduced 32%, 22%, 30%, 14% and 36%, respectively. The results also showed that the trend of changes in sleep duration, sleep disturbance, sleep latency, and sleep efficiency indices had

  7. Neuroendocrine mechanisms in athletes.

    PubMed

    Athletic activity may be associated with alterations in various neuroendocrine axes depending on the state of energy availability. In addition, genetic factors and an underlying predilection for polycystic ovarian syndrome (PCOS) may predispose some athletes to develop functional hypothalamic amenorrhea earlier than other athletes. In conditions of low energy availability associated with athletic activity, changes that occur in various neuroendocrine axes are primarily adaptive, and aim to either conserve energy for the most essential functions, or allow the body to draw on its reserves to meet energy needs. These hormonal changes, however, then lead to changes in body composition and bone metabolism. Impaired bone accrual in younger athletes and low bone density in older athletes constitutes the major pathologic consequence of neuroendocrine changes associated with low energy availability. The female athlete triad of low energy availability, menstrual dysfunction, and low bone density is prevalent in certain kinds of sports and activities, particularly endurance sports, gymnastics, and ballet. It is essential to screen for this condition in athletes at every preparticipation physical and during office visits, and to put in place an effective treatment team to manage the triad early, in order to optimize outcomes.

    Objective. Ultrasonographic characteristics are associated with thyroid malignancy. Our aim was to compare the diagnostic value of ultrasound features in the detection of thyroid malignancy in both solid and mixed nodules. Methods. We prospectively studied female patients (≥50 years) referred to ultrasound-guided fine needle aspiration biopsy. Ultrasound features considered suspicious were hypoechogenicity, microcalcifications, irregular margins, high anteroposterior (AP)/axial-ratio, and absent halo. Associations were separately assessed in mixed and solid nodules. Results. In a group of 504 elderly female patients (age = 69 ± 8 years), the frequency of malignant cytology was 6%. Thirty-one percent of nodules were mixed and 60% were solid. The rate of malignant cytology was similar for mixed and solid nodules (7.4 versus 5.8%, P: 0.56). While in mixed nodules none of the ultrasound characteristics were associated with malignant cytology, in solid nodules irregular margins and microcalcifications were significant (all P < 0.05). The combination of irregular margins and/or microcalcifications significantly increased the association with malignant cytology only in solid nodules (OR: 2.76 (95% CI: 1.25-6.10), P: 0.012). Conclusions. Ultrasound features were of poor diagnostic value in mixed nodules, which harbored malignant lesions as often as solid nodules. Our findings challenge the recommended minimal size for ultrasound-guided fine needle aspiration biopsy in mixed nodules.

    The aim of this case study is to describe the nutrition practices of a female recreational runner (VO2max 48.9 ml·kg(-1)·min(-1)) who completed 26 marathons (42.195 km) in 26 consecutive days. Information relating to the nutritional intake of female runners during multi-day endurance events is extremely limited, yet the number of people participating year-on-year continues to increase. This case study reports the nutrition intervention, dietary intake, body composition changes and performance in the lead-up and during the 26 days. Prior to undertaking the 26 marathon challenge, three consultations were held between the athlete and a sports nutrition advisor; planning and tailoring the general diet and race-specific strategies to the endurance challenge. During the marathons, the mean energy and fluid intake was 1039.7 ± 207.9 kcal (607.1 - 1453.2) and 2.39 ± 0.35 L (1.98 - 3.19). Mean hourly carbohydrate intake was 38.9 g·hr(-1). 11 days following the completion of the 26 marathons, body mass had reduced by 4.6 kg and lean body mass increasing by 0.53 kg when compared with 20 days prior. This case study highlights the importance of providing general and event-specific nutrition education when training for such an event. This is particularly prudent for multi-day endurance running events.

    To describe the architecture and topohistology of the female perineal structures, especially the perineal membrane (PM), we examined frontal sections (one side) and horizontal or transverse sections (another side) of 15 bisectioned pelvic floors. The PM, notably comprising elastic fibers, extended mediolaterally or transversely on the immediately inferior side of the rhabdosphincter area. More posteriorly, the elastic fibers more tilted along the long axis of the vagina and became lining the lateral vaginal wall as a fibrous skeleton. The compressor urethrae and urethrovaginal sphincter were embedded in and interdigitated with the PM. The elastic fiber architecture of the PM was similar to the rectovaginal septum. We hypothesize that the PM plays a role of a shock-absorber at the interface between the levator ani and distalmost vagina. A standard diagram of the female perineal structures is necessary to be revised.

    A 5-y prospective study of the changes in radial-bone mineral density (BMD) of elderly white women (mean age, 81 y) living in four residential communities, including 49 Seventh-day Adventist lacto-ovovegetarians and 140 omnivores, was undertaken to determine the potential effects of usual dietary calcium in preventing the loss of BMD, measured by single-photon absorptiometry, at two radial sites. Changes in BMD and other variables from baseline (1983) to follow-up (1988) were: 1) mean calcium intakes in 1988 of 996 mg/d for omnivores and 733 mg/d for lacto-ovovegetarians changed little from 1983, 2) all women lost BMD (P < 0.05) over the 5 y period, 3) the annual BMD loss rates were approximately 1% at each site, 4) BMD loss was independent of calcium intake, 5) BMD loss rates were similar in both lacto-ovovegetarians and omnivores, and 6) the greater the loss of lean body mass, the greater the BMD loss (P < 0.05).

    Menaquinone-7 (MK-7) is vitamin K2 which is a series of vitamins with multiisoprene units at the 3-position of the naphthoquinone. MK-7 has been shown to prevent bone loss in ovariectomized rats, an animal model for osteoporosis. This study was undertaken to determine whether MK-7 has a stimulatory effect on bone components of elderly female rats in vitro. The femoral-diaphyseal and -metaphyseal tissues obtained from young (4 weeks old) or elderly (50 weeks old) female rats were cultured for 48 h in a Dullbecco's modified Eagle's medium (high glucose, 4.5%) supplemented with antibiotics and bovine serum albumin. Calcium content, alkaline phosphatase activity and deoxyribonucleic acid (DNA) in the diaphyseal and metaphyseal tissues obtained from elderly rats were significantly decreased as compared with those of young rats, indicating that aging causes a deterioration of bone formation. The presence of MK-7 (10(-6) or 10(-5) M) caused a significant increase in biochemical components in the femoral-diaphyseal and -metaphyseal tissues obtained from elderly rat in vitro. The anabolic effect of MK-7 (10(-6) or 10(-5) M) on the femoral calcium content was significantly enhanced in the presence of phytoestrogen genistein (10(-6) or 10(-5) M), suggesting that the mode of action of MK-7 differ from that of genistein. The effect of MK-7 (10(-5) M) in increasing calcium content, alkaline phosphatase activity and DNA content in the diaphyseal and metaphyseal tissues was completely abolished in the presence of cycloheximide (10(-6) M), an inhibitor of protein synthesis in vitro. These findings demonstrate that MK-7 has a stimulatory effect on bone formation in the femoral tissues of elderly female rats in vitro. MK-7 may have a preventive role for bone deterioration with aging.

    The purpose of this study was to investigate the effects of adding heavy strength training to female duathletes' normal endurance training on both cycling and running performance. Nineteen well-trained female duathletes (VO2max cycling: 54 ± 3 ml∙kg(-1)∙min(-1), VO2max running: 53 ± 3 ml∙kg(-1)∙min(-1)) were randomly assigned to either normal endurance training (E, n = 8) or normal endurance training combined with strength training (E+S, n = 11). The strength training consisted of four lower body exercises [3 × 4-10 repetition maximum (RM)] twice a week for 11 weeks. Running and cycling performance were assessed using 5-min all-out tests, performed immediately after prolonged periods of submaximal work (3 h cycling or 1.5 h running). E+S increased 1RM in half squat (45 ± 22%) and lean mass in the legs (3.1 ± 4.0%) more than E Performance during the 5-min all-out test increased in both cycling (7.0 ± 4.5%) and running (4.7 ± 6.0%) in E+S, whereas no changes occurred in E The changes in running performance were different between groups. E+S reduced oxygen consumption and heart rate during the final 2 h of prolonged cycling, whereas no changes occurred in E No changes occurred during the prolonged running in any group. Adding strength training to normal endurance training in well-trained female duathletes improved both running and cycling performance when tested immediately after prolonged submaximal work.

    Anterior cruciate ligament injuries are common, expensive to repair, and often debilitate athletic careers. Robotic manipulators have evaluated knee ligament biomechanics in cadaveric specimens, but face limitations such as accounting for variation in bony geometry between specimens that may influence dynamic motion pathways. This study examined individual anthropometric measures for significant linear relationships with in vivo kinematic and kinetic performance and determined their implications for robotic studies. Anthropometrics and 3D motion during a 31 cm drop vertical jump task were collected in high school female basketball players. Anthropometric measures demonstrated differential statistical significance in linear regression models relative to kinematic variables (p-range <0.01-0.95). However, none of the anthropometric relationships accounted for clinical variance or provided substantive univariate accuracy needed for clinical prediction algorithms (r(2) < 0.20). Mass and BMI demonstrated models that were significant (p < 0.05) and predictive (r(2) > 0.20) relative to peak flexion moment, peak adduction moment, flexion moment range, abduction moment range, and internal rotation moment range. The current findings indicate that anthropometric measures are less associated with kinematics than with kinetics. Relative to the robotic manipulation of cadaveric limbs, the results do not support the need to normalize kinematic rotations relative to specimen dimensions.

    We undertook a 2 year pilot study in premenopausal and postmenopausal females and male partners in which the subjects were administered a bisphosphonate, alendronate, for 6 months. The aim ot the study was to determine how lead isotopes and lead concentrations changed in relation to bone remodelling processes. Each subject had blood and urine samples collected for markers of bone turnover and for lead isotope studies monthly for 7-9 months before and then 3 monthly during and for up to 6 months after treatment with alendronate as an agent for inhibiting bone resorption. There were significant decreases in the lead isotope ratio, ^{206}Pb/^{204}Pb, for the migrant subjects cluring treatment compared with thepre-treatment period (p<0.01). The average bloodlead concentrations in migrant subjects decreased by about 20% during the treatment compared with the pre-treatment period (p<0.01). The changes in lead isotopic composition and lead concentration are consistent with a decrease m bone résorption and associated mobilisation of lead during alendronate therapy.

    Pyometra is collection of pus within the uterine cavity and is usually associated with underlying gynaecological malignancy or other benign causes. Spontaneous rupture of pyometra is a rare complication. We report a case of a 65-year-old female who presented with acute abdomen and was diagnosed with a ruptured uterus secondary to pyometra and consequent peritonitis on dynamic transvaginal sonography (TVS) which was later confirmed on contrast enhanced computed tomography (CECT). An emergency laparotomy was performed and about 800 cc of pus was drained from the peritoneal cavity. A rent was found in the anterior uterine wall and hence hysterectomy was performed. Histopathology revealed mixed inflammatory cell infiltrate with no evidence of malignancy. There are only 31 cases of ruptured pyometra reported till date, most of which were definitively diagnosed only on laparotomy. In only two of these cases the preoperative diagnosis was made on CECT. We report this case, as the correct and definitive diagnosis was made preoperatively on dynamic TVS. To our knowledge, this is the first case report revealing spontaneous ruptured pyometra being diagnosed preoperatively on dynamic TVS. This report is aimed at giving emphasis on the use of simple dynamic TVS for accurate diagnosis of rare spontaneous ruptured pyometra causing peritonitis.

    Pulmonary mycosis is seen infrequently in our country. It is more common in the immunocompromised. The infections caused by less known species like Fusarium have been found to be increasing in incidence in other parts of the world. We hereby report its occurrence in a 79-year-old, non-immunocompromised female who presented with pyrexia of unknown origin. Her Alanine Phosphatase (ALP) and Lactate Dehydrogenase (LHD) levels were raised. CT scan showed interstitial thickening in subpleural aspect of lungs and multiple enlarged lymph nodes in mediastinum. Liver showed multiple hypodense lesions. Metastasis was suspected for which Fine Needle Aspiration Cytology (FNAC) of liver was done which showed foci of regenerative hepatocytes with desmoplastic stromal tissue fragments and negative for tumour. Her Alpha Fetoprotein (AFP) was normal. The bronchial tree cytology showed endobronchial cells, dust-laden macrophages and chronic inflammatory cells along with fungi on Pap smear studies. This was confirmed by culture that grew Fusarium species. after one week of incubation. The acutely branching septate hyphae of Fusarium species are identical to those of Aspergillus species. In a patient who has a disseminated infection with a septate fungus, growth in culture is important to identify the specific organism and subsequently treatment with appropriate antifungals. In cases like ours, where the infection simulates malignancy, it is even more important to make the correct diagnosis to give the appropriate treatment. PMID:28384871

    Bone health is considered not to benefit from water-based sports because of their weight-supported nature, but available evidence primarily relies on DXA technology. Our purpose was to investigate musculoskeletal health in the upper and lower body in well-trained adolescent female athletes using pQCT and compare these athletes with less-active, age- and sex-matched peers. Bone mineral content, volumetric cortical and trabecular BMD, total and cortical area, and bone strength index were assessed at the distal and proximal tibia and radius in four groups of adolescent females (mean age, 14.9 years) including water polo players (n = 30), gymnasts (n = 25), track-and-field athletes (n = 34), and nonactive controls (n = 28). Water polo players did not show any benefit in bone strength index or muscle size in the lower leg when compared with controls. In contrast, gymnasts showed 60.1 % and 53.4 % greater bone strength index at the distal and proximal tibia, respectively, than nonactive females (p < 0.05). Similarly, track-and-field athletes displayed 33.9 % and 14.7 % greater bone strength index at the distal and proximal tibia, respectively, compared with controls (p < 0.05). In the upper body, water polo players had 31.9 % greater bone strength index at the distal radius, but not the radial shaft, and 15.2 % larger forearm muscle cross-sectional area than controls (p < 0.05). The greatest musculoskeletal benefits in the upper body were found in gymnasts. In conclusion, despite training at an elite level, female water polo players did not show any benefits in musculoskeletal health in the lower leg and only limited benefits in the upper body when compared with nonactive girls.

    Sexual function in aging women Sexuality is an integral part of human expressions. Mental health plays a major role in sexuality. Several psychological interventions are proposed to increase the sexual quality of life in older women with diverse gynecologic pathology. A biopsychosocial approach utilizing brief strategies can be easily implemented in clinics to help women of all ages increase their sexual quality of life. The impact of female pelvic floor disorders on sexual function in older women Female pelvic floor disorders include urinary incontinence, pelvic organ prolapse, and fecal incontinence. These disorders increase dramatically with increasing age. Urinary incontinence has been demonstrated to have a negative impact on a woman’s sexual function. Among sexually active older women with urinary incontinence, 22% report being moderately or extremely worried that sexual activity would cause urine loss. An increased prevalence of sexual distress [9% (6/76) vs. 1.3% (2/216), p=0.005] has been reported in sexually active women over 40 years old with urinary incontinence. Treatment of urinary incontinence can improve sexual function in older women. Among sexually active women (N=53) who underwent midurethral slings procedures for the correction of urinary incontinence, increased coital frequency, decrease fear of incontinence with coitus, decreased embarrassment due to incontinence was reported six months after surgery. Pelvic organ prolapse, a hernia of the vagina resulting in a visible vaginal bulge, has also been associated with a negative impact on sexual function. Women with advanced pelvic organ prolapse (POP-Q stage III or IV) have been demonstrated to have decreased body image reporting that they are more self-conscious about their appearance [adjusted odds ratio (AOR) 4.7; 95% confidence interval (CI) 2.9, 51], feel less feminine (AOR 4.0; 95% CI 1.2, 15) and less sexually attractive (AOR 4.6; 95% CI 1.4, 17) compared with women who have normal pelvic

    Data from student-athletes at 15 colleges and universities (N = 4,258) document extensive misperceptions of peer drinking norms and their association with personal quantity of alcohol consumed. Regardless of actual drinking norms at each school, student-athletes commonly overestimated the alcohol consumption norms (both quantity and frequency…

    Aim Our study aimed to investigate changes of different markers for routine assessment of fatigue and recovery in response to high-intensity interval training (HIIT). Methods 22 well-trained male and female team sport athletes (age, 23.0 ± 2.7 years; V̇O2max, 57.6 ± 8.6 mL·min·kg−1) participated in a six-day running-based HIIT-microcycle with a total of eleven HIIT sessions. Repeated sprint ability (RSA; criterion measure of fatigue and recovery), countermovement jump (CMJ) height, jump efficiency in a multiple rebound jump test (MRJ), 20-m sprint performance, muscle contractile properties, serum concentrations of creatinkinase (CK), c-reactive protein (CRP) and urea as well as perceived muscle soreness (DOMS) were measured pre and post the training program as well as after 72 h of recovery. Results Following the microcycle significant changes (p < 0.05) in RSA as well as in CMJ and MRJ performance could be observed, showing a decline (%Δ ± 90% confidence limits, ES = effect size; RSA: -3.8 ± 1.0, ES = -1.51; CMJ: 8.4 ± 2.9, ES = -1.35; MRJ: 17.4 ± 4.5, ES = -1.60) and a return to baseline level (RSA: 2.8 ± 2.6, ES = 0.53; CMJ: 4.1 ± 2.9, ES = 0.68; MRJ: 6.5 ± 4.5, ES = 0.63) after 72 h of recovery. Athletes also demonstrated significant changes (p < 0.05) in muscle contractile properties, CK, and DOMS following the training program and after the recovery period. In contrast, CRP and urea remained unchanged throughout the study. Further analysis revealed that the accuracy of markers for assessment of fatigue and recovery in comparison to RSA derived from a contingency table was insufficient. Multiple regression analysis also showed no correlations between changes in RSA and any of the markers. Conclusions Mean changes in measures of neuromuscular function, CK and DOMS are related to HIIT induced fatigue and subsequent recovery. However, low accuracy of a single or combined use of these markers requires the verification of their applicability on an

    Since previous numbers-needed-to-treat (NNT) and relative risk reduction (RRR) report, a few studies were published to evaluate prophylactic effectiveness of neuromuscular training for anterior cruciate ligament (ACL) injury in female athletes. The purpose of the current analyses was to determine the effectiveness of neuromuscular training interventions in reducing both non-contact and overall ACL injury risk in female athletes through RRR and NNT. The keywords 'knee', 'anterior cruciate ligament', 'ACL', 'prospective', 'neuromuscular', 'training', 'female' and 'prevention' were searched to find studies published from 1995 to 2011 in PubMed and EBSCO (CINAHL, Health source, MEDLINE and SPORT Discus). Inclusion criteria required that relevant studies: recruited physically active young girls as subjects, documented the number of ACL injuries, employed a neuromuscular training intervention, and used a prospective controlled study design. The numbers of non-contact and overall ACL injuries, subjects and observation time period were used to calculate RRR and NNT for each study. A total of 12 studies met the inclusion criteria. There was a 73.4% (95% CI 62.5% to 81.1%) and 43.8% (95% CI 28.9% to 55.5%) of RRR for non-contact and overall ACL injuries. From the NNT analysis, it was determined that, respectively, 108 (95% CI 86 to 150) and 120 (95% CI 74 to 316) individuals would need to be trained to prevent one non-contact or one overall ACL injury over the course of one competitive season. Although the RRR analysis indicated prophylactic benefits of neuromuscular training, the relatively large NNT indicated that many athletes are needed to prevent one ACL injury. A future direction to reduce NNT and improve the efficiency of ACL injury-prevention strategies is to develop a screening system for identifying at-risk athletes.

  10. Analysis of Training Load and Competition During the PhD Course of a 3000-m Steeplechase Female Master Athlete: An Autobiography

    The first author, Elisa Gabrielli, has been a distance runner for many years, and then at a particular point in her career, she decided to move over to the 3000-m steeplechase. She was attracted by this discipline as she believed that it would be the appropriate discipline for her, due to the challenge it provided her, and the necessary knowledge and awareness she had through her studies. For reasons that are discussed in this report, the 3000-m steeplechase is a race that is more difficult to interpret and manage biomechanically and physiologically than most others. Combining this with her PhD allowed her to use a multidisciplinary approach to review the competitive experience gained in this discipline. During this period, she indeed not only deepened the technical aspects of her training, but also those that underlie this discipline, through her knowledge of sport, with particular reference to the female athlete. Through her technical research, she was able to take ‘snapshots’ of what could happen from the physiological point of view. With satisfaction, she improved her performance in the 3000-m race and in the 3000-m steeplechase. How? In particular, she worked on her running technique through specific exercises. She worked on de-contraction and posture, while saving energy consumption. She worked on the control of her breathing, and she took into account her prevailing heart rate. This was all in combination with the consumption of specific nutrients, as she tried to manage the production of lactate with the training of the red muscle fibres that are rich in mitochondria. Finally, she tried to improve her perception of strenuous work, by training at high altitude. This allowed her not only to improve her physical performance, but especially to improve her mind-set, which allowed her to be more confident in herself and her abilities. PMID:26913156

    A 14-year-old Caucasian girl was referred to the endocrine clinic for evaluation of voice deepening, facial hirsutism, and acne starting 2 years previously. She had been a competitive tennis player since age 7 years, practicing for 4-6 hours daily. On physical examination she was noticed to have a masculine appearance with mild facial acne and moderate hirsutism. Tanner stage was 1 for breast tissue and 5 for pubic hair. Her androgen levels (testosterone, androstenedione, dehydroepiandrosterone sulfate) were extremely elevated. Adrenal ultrasonography revealed a round left 4.6 × 5.3-cm adrenal mass. Laparoscopic left adrenalectomy was performed. The histologic findings were compatible with a benign adrenocortical tumor. Postoperatively, androgen levels dropped to within the normal range. Breast development proceeded normally, menarche occurred 2 months after tumor resection, and menses has been regular since then. Muscle strength of the dominant and nondominant upper and lower extremities was measured 1 month before surgery and 1 year later, using an isokinetic dynamometer (Biodex Systems II, Biodex, Shirley, NY, USA). There was no significant decrease in overall muscle strength after removal of the virilizing tumor and the marked drop in circulating androgens. In addition, the patient maintained her age category, number 1, national tennis ranking. The results suggest that even extremely high levels of tumor-related circulating androgens had no evident effect on muscle strength and competitive performance in a female adolescent tennis player. The lack of beneficial effect on performance in adolescents, combined with the potentially hazardous side effects of anabolic steroids, suggests that teenage athletes should avoid their use.

    Background Athletes who return to sport after anterior cruciate ligament reconstruction are at increased risk of future ACL injury. Altered coordination of lower extremity motion may increase this risk. The purpose of this study was to prospectively determine if altered lower extremity coordination patterns exist in athletes who go on to sustain a 2nd anterior cruciate ligament injury. Methods Sixty-one female athletes who were medically cleared to return to sport after anterior cruciate ligament reconstruction were included. Hip-ankle coordination was assessed prior to return to sport with a dynamic postural coordination task. Within 12 months, 14 patients sustained a 2nd ACL injury. Fourteen matched subjects were selected for comparative analysis. Cross-recurrence quantification analysis characterized hip-ankle coordination patterns. A group × target speed (slow vs. fast) × leg (involved vs. uninvolved) analysis of variance was used to identify coordination differences. Findings A main effect of group (p = 0.02) indicated that the single injury group exhibited more stable hip-ankle coordination [166.2 (18.9)] compared to the 2nd injury group [108.4 (10.1)]. A leg × group interaction was also observed (p = .04). The affected leg of the single injury group exhibited more stable coordination [M = 187.1 (23.3)] compared to the affected leg of the 2nd injury group [M = 110.13 (9.8)], p = 0.03. Interpretation Hip-ankle coordination was altered in female athletes who sustained a 2nd anterior cruciate ligament injury after return to sport. Failure to coordinate lower extremity movement in the absence of normal knee proprioception may place the knee at high-risk. PMID:26416200

    We hypothesized that 24-hour urinary excretion of water-soluble vitamins might correlate with their intake in free-living Japanese elderly females aged 70 to 84 years. We performed a cross-sectional study composed of 37 healthy, elderly, Japanese females living freely. All foods and the corresponding weights consumed for 4 consecutive days were recorded accurately. A 24-hour urine sample was collected on the fourth day, and the urinary content of water-soluble vitamins was measured. The urinary levels of all vitamins, except for B(12) (r = 0.01; P = .936), were correlated positively with the mean intake over the recent 4 days (vitamin B1: r = 0.62; P < .001; vitamin B2: r = 0.57; P < .001; vitamin B6: r = 0.37; P < .005; niacin: r = 0.54; P < .001; niacin equivalents: r = 0.54; P < .001; pantothenic acid: r = 0.59; P < .001; folate: r = 0.55; P = .001; and vitamin C: r = 0.53; P < .001). Mean estimated intakes of water-soluble vitamins calculated using urinary concentrations and recovery rates showed 96% to 107% of their 3-day mean intake, except for vitamin B12 (65%). We conclude that urinary levels of water-soluble vitamins, except for B12, reflected their recent intake in free-living Japanese elderly females and could be used as a measure of their intake during the previous few days both for group means and for individual rankings within a group.

    2012-01-01

    This study examined the effects of two different warm-up protocols on lower limb power and flexibility in high level athletes. Twenty international level fencers (10 males and 10 females) performed two warm-up protocols that included 5-min light jogging and either short (15s) or long (45s) static stretching exercises for each of the main leg muscle groups (quadriceps, hamstrings and triceps surae), followed by either 3 sets of 3 (short stretching treatment), or 3 sets of 5 tuck jumps (long stretching treatment), in a randomized crossover design with one week between treatments. Hip joint flexion was measured with a Lafayette goniometer before and after the 5-min warm-up, after stretching and 8 min after the tuck jumps, while counter movement jump (CMJ) performance was evaluated by an Ergojump contact platform, before and after the stretching treatment, as well as immediately after and 8 minutes after the tuck jumps. Three way ANOVA (condition, time, gender) revealed significant time (p < 0.001) and gender (p < 0.001) main effects for hip joint flexion, with no interaction between factors. Flexibility increased by 6. 8 ± 1.1% (p < 0.01) after warm-up and by another 5.8 ± 1.6% (p < 0.01) after stretching, while it remained increased 8 min after the tuck jumps. Women had greater ROM compared with men at all time points (125 ± 8° vs. 94 ± 4° p<0.01 at baseline), but the pattern of change in hip flexibility was not different between genders. CMJ performance was greater in men compared with women at all time points (38.2 ± 1.9 cm vs. 29.8 ± 1.2 cm p < 0.01 at baseline), but the percentage of change CMJ performance was not different between genders. CMJ performance remained unchanged throughout the short stretching protocol, while it decreased by 5.5 ± 0.9% (p < 0.01) after stretching in the long stretching protocol However, 8 min after the tuck jumps, CMJ performance was not different from the baseline value (p = 0.075). In conclusion, lower limb power may be

  16. Coaching preferences of athletes.

    The study examined the coaching preferences of 80 male and 80 female athletes, as measured by the Leadership Scale for Sports (Chelladurai and Saleh, 1978, 1980). In addition, it attempted to assess the applicability to sport of the Life-cycle and Path-goal theories of leadership. Comparisons between groups were made on the basis of sex, age, and type of sport. A MANOVA indicated that athletes in independent sports preferred more democratic behaviour (p less than .001) and less autocratic behaviour (p = .028) than athletes in interdependent sports. No differences in coaching preferences were found which could be attributed to the age or sex of the athlete, or the variability of the sports task. These results partially supported the Path-goal theory, but did not support the Life-cycle theory. Athletes of all groups tended to favour coaches who displayed training behaviour and rewarding behaviour "often", democratic behaviour and social support behaviour "occasionally", and autocratic behaviour "seldom". This consistency may be a useful finding for those organizations and institutions interested in preparing coaches.

  17. The Athletic Body.

    PubMed

    Edgar, Andrew

    2016-09-10

    This paper seeks to explore the attraction and the beauty of the contemporary athletic body. It will be suggested that a body shaped through muscular bulk and definition has come to be seen as aesthetically normative. This body differs from the body of athletes from the early and mid-twentieth century. It will be argued that the contemporary body is not merely the result of advances in sports science, but rather that it is expressive of certain meanings and values. The visual similarity of the contemporary athletic body and that of the comic book superhero suggests that both bodies carry a similar potential for narrative story-telling, and that their attraction is bound up with this narrative potential. The superhero and athlete live meaningful lives, pursuing clear and morally unambiguous goals. The aesthetic attraction of the body lies in its capacity to facilitate the articulation of a story of a meaningful life, and to do so in the face of the growing anomie and thus meaninglessness of life as experienced in contemporary society. Athleticism offers an illusion of meaning, serving to reproduce dominant justificatory narratives and social stereotypes. Yet, as an illusion of meaning, it may be challenged and negotiated, not least with respect to its bias towards a certain form of the male body. The female athletic body disrupts the illusion, opening up new existential possibilities, new ways of living and being, and thus new, and potentially disruptive, narratives.

    There is limited research investigating antagonist stretch. The purpose of this study was to evaluate the influence of SSH on performance and ACL injury risk during stop-jump and 180° cutting tasks. Twelve female college athletes (age 20.8 ± 0.7 years; height 1.61 ± 0.05 m; mass 54.25 ± 4.22 kg) participated in this study. Subjects performed stop-jump and 180° cutting tasks under two conditions: after warm-up with 4×30 s SSH or after warm-up without SSH. Three-dimensional kinematic and kinetic data as well as EMG of biceps femoris (BF), rectus femoris (RF), vastus medialis (VM), and gastrocnemius medialis (GM) were collected during testing. SSH significantly enhanced jump height by 5.1% (P = 0.009), but did not change the takeoff speed of cutting. No significant changes in peak knee adduction moment or peak anterior tibia shear force were observed with SSH regardless of the task. The peak lateral tibia shear force during cutting was significantly (P = 0.036) reduced with SSH. The co-contraction of hamstring and quadriceps during the preactivation (stop-jump: P = 0.04; cutting: P = 0.05) and downward phases (stop-jump: P = 0.04; cutting: P = 0.05) was significantly reduced after SSH regardless of the task. The results suggest that SSH enhanced the performance of stop-jump due to decreased co-contraction of hamstring and quadriceps, but did not change the performance of cutting. In addition, SSH did not increase ACL injury risk during stop-jump and cutting tasks and even reduced medial-lateral knee loading during cutting.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND) , where it is permissible to download and share the work provided it is properly cited.

    The relationship between participation in highly competitive exercise, thigh muscle strength, and regional and total body bone mineral density (BMD) in elite senior athletes and healthy elderly controls was investigated. One hundred and four elite senior athletes (age: 72.6 ± 6.4 years, height: 168.7 ± 8.6 cm, mass: 72.6 ± 13.5 kg, 57 male:47 female) and 79 healthy controls (age: 75.4 ± 5.6 years, height: 170.8 ± 25.5 cm, mass: 79.5 ± 11.7 kg, 46 male:33 female) participated in this cross-sectional study. Vitamin D and calcium intake were assessed via a recall survey. Isometric knee extension and flexion peak torque were measured via a custom strength measurement device. Total body and regional BMD of the hip, radius, and spine were assessed with a dual-energy x-ray absorptiometer. For each BMD site assessed, multivariate linear regression analysis was performed in 4 steps (α = 0.10) to examine the contribution of (a) age, sex, bodyweight, and calcium and vitamin D intake; (b) group (elite senior athlete, control); (c) knee extension peak torque; and (d) knee flexion peak torque on BMD. Sex, age, bodyweight, and calcium and vitamin D intake explained a significant amount of variance in BMD in each site. Group was not significant. Knee extension peak torque explained an additional 3.8% of the variance in hip BMD (p = 0.06). Knee flexion peak torque was not correlated to BMD at any of the sites assessed. In conclusion, participation in highly competitive athletics was not related to total body or regional BMD. Age, sex, bodyweight, and vitamin D and calcium intake were significantly related to BMD at all the sites assessed. Quadriceps strength contributed slightly to hip BMD. Our results imply that participation in highly competitive senior athletics does not have a protective effect on BMD, perhaps because of a lower bodyweight or other confounding factors.

    2011-07-29

    In the current study the author examined whether ethnocultural empathy affects people's beliefs and expectations regarding athletes, hypothesizing that (1) individuals demonstrating a high level of ethnocultural empathy would be less likely to endorse stereotypes toward athletes, (2) females would be less likely to stereotype toward athletes than would males, (3) athletes would be less likely to stereotype toward athletes than would non-athletes, and (4) behavioral science majors would be less likely to stereotype toward athletes than would non-behavioral science majors. As predicted, participants high on ethnocultural empathy were less likely to stereotype towards athletes, females were less likely to stereotype toward athletes than were males, and behavioral science majors were less likely to stereotype toward athletes than were non-behavioral science majors. However, contrary to the hypotheses, athletes were more likely to stereotype toward their own in-group than were non-athletes.

    1996-01-01

    There have been no previous studies of athletic trainers' educational practices regarding breast or testicular cancer, so we surveyed athletic trainers regarding: 1) the incidence of cancer among athletes, 2) educational practices concerning breast/testicular cancer, 3) educational practices regarding breast/testicular self-examination, 4) breast/testicular concerns of athletes, 5) breast self-examination and testicular self-examination among athletic trainers. A researcher-developed questionnaire was randomly distributed to athletic trainers at the 1994 NATA convention, and SPSS-X was used to analyze results, using Chi-square. One alarming finding was that 28% of athletic trainers surveyed had worked with an athlete who had cancer. Twenty-two percent of the athletic trainers surveyed reported that a female athlete had brought a breast concern to them, and 51% reported that a male athlete had brought a testicular concern to them. Most of the athletic trainers surveyed do not educate athletes about breast or testicular cancer and do not teach athletes about self-examination procedures, but do perform breast self-examination or testicular self-examination on themselves. Acting as a role model is an important step toward the education of athletes in our care, but more must be done. As health care professionals, athletic trainers must become more proactive, rather than reactive, when dealing with cancer prevention. PMID:16558366

    Abstract Context: Researchers have investigated heterosexuals' attitudes toward homosexuals, focusing on factors such as sex, race, religion, education, and contact experiences. However, in the context of sport, this research is deficient. We found no published literature investigating athletic trainers (ATs') attitudes toward lesbian, gay, and bisexual student-athletes (LGB). Objective: To determine heterosexual ATs' attitudes toward LGB student-athletes in the National Collegiate Athletic Association. Design: Cross-sectional study Setting: E-mailed survey. Patients or Other Participants: A total of 964 ATs employed at member institutions. Main Outcome Measure(s): We measured attitudes using the Attitudes Toward Lesbian, Gay Men, and Bisexuals (ATLGB) Scale. To determine the extent to which sex, religion, and whether having an LGB friend or family member had an effect on ATs' attitudes, we performed analysis of variance. To establish the effect of age on ATs' attitudes, we calculated a Pearson correlation. We used an independent t test to identify differences between ATs who reported working with LGB student-athletes and ATs who did not. Results: With ATLGB score as the dependent factor, a main effect was noted for sex, religion, and having an LGB friend or family member (P < .01 for all comparisons). Age and total score were related (P < .01). A difference was seen in the ATLGB scores between ATs who were aware of LGB student-athletes on their teams and ATs who were not (P < .001). Conclusions: Many ATs hold positive attitudes toward LGB student-athletes, especially females, those who have an LGB friend or family member, and those who are aware of LGB student-athletes. Still, it is important to provide an open environment in the athletic training room for all student-athletes. PMID:21214353

    1990-10-01

    Although overt anemia is uncommon, depletion of body iron stores is common among adolescent female athletes. Poor dietary iron intake, menstruation, and increased iron losses associated with physical training all appear to be important factors. Whether nonanemic iron deficiency can impair exercise performance is uncertain. Nonetheless, athletes with low ferritin levels are at risk for impaired erythropoiesis and should receive therapeutic iron supplementation.

    In exploring the relationship between wellness and athletic performance, this study assessed the link between wellness, as defined by a high score on five wellness dimensions of emotional, social, spiritual, intellectual, and physical well-being, with psychological variables thought to be related to athletic performance as measured by athletes' self-report of specific athletic coping skills. 142 collegiate athletes completed a survey composed of the Optimal Living Profile to measure wellness dimensions and the Athletic Coping Skills Inventory to measure specific psychological variables. Analysis indicated that athletes scoring higher on the dimensions of wellness also scored significantly higher on athletic coping skills. Specifically, male athletes who scored higher on wellness also reported higher scores on coachability, concentration, goal setting/mental preparation, and peaking under pressure, and female athletes who scored higher on wellness also reported higher scores in coping with adversity, coachability, concentration, goal setting/mental preparation, and freedom from worry. Various dimensions of wellness seem related to better performance by involving the athletic coping skills of intercollegiate athletes. Implications for coaches and sport psychologists are also discussed.

    To be successful in international competitions, judo athletes must achieve an excellent level of physical fitness and physical condition during training. This article reviews the physiological profiles of elite judo athletes from different sex, age and weight categories. Body fat is generally low for these athletes, except for the heavyweight competitors. In general, elite judo athletes presented higher upper body anaerobic power and capacity than non-elite athletes. Lower body dynamic strength seems to provide a distinction between elite and recreational judo players, but not high-level judo players competing for a spot on national teams. Even maximal isometric strength is not a discriminant variable among judo players. However, more studies focusing on isometric strength endurance are warranted. Although aerobic power and capacity are considered relevant to judo performance, the available data do not present differences among judo athletes from different competitive levels. Typical maximal oxygen uptake values are around 50-55 mL/kg/min for male and 40-45 mL/kg/min for female judo athletes. As for other variables, heavyweight competitors presented lower aerobic power values. The typical differences commonly observed between males and females in the general population are also seen in judo athletes when analysing anaerobic power and capacity, aerobic power, and maximal strength and power. However, further research is needed concerning the differences among the seven weight categories in which judo athletes compete.

  17. Effects of a shoulder injury prevention strength training program on eccentric external rotator muscle strength and glenohumeral joint imbalance in female overhead activity athletes.

    Imbalance of the eccentrically-activated external rotator cuff muscles versus the concentrically-activated internal rotator cuff muscles is a primary risk factor for glenohumeral joint injuries in overhead activity athletes. Nonisokinetic dynamometer based strength training studies, however, have focused exclusively on resulting concentric instead of applicable eccentric strength gains of the external rotator cuff muscles. Furthermore, previous strength training studies did not result in a reduction in glenoumeral joint muscle imbalance, thereby suggesting that currently used shoulder strength training programs do not effectively reduce the risk of shoulder injury to the overhead activity athlete. Two collegiate women tennis teams, consisting of 12 women, participated in this study throughout their preseason training. One team (n = 6) participated in a 5-week, 4 times a week, external shoulder rotator muscle strength training program next to their preseason tennis training. The other team (n = 6) participated in a comparable preseason tennis training program, but did not conduct any upper body strength training. Effects of this strength training program were evaluated by comparing pre- and posttraining data of 5 maximal eccentric external immediately followed by concentric internal contractions on a Kin-Com isokinetic dynamometer (Chattecx Corp., Hixson, Tennessee). Overall, the shoulder strength training program significantly increased eccentric external total work without significant effects on concentric internal total work, concentric internal mean peak force, or eccentric external mean peak force. In conclusion, by increasing the eccentric external total exercise capacity without a subsequent increase in the concentric internal total exercise capacity, this strength training program potentially decreases shoulder rotator muscle imbalances and the risk for shoulder injuries to overhead activity athletes.

    Summary Background Persons with an optimistic attitude do not give up despite obstacles and failures. Optimistic athletes compete more out of hope for success than out of fear of defeat. The purpose of my research was to determine if optimism also promotes good health behavior in athletes. Material/Methods In order to measure the role of optimism in shaping the health behavior of athletes, I examined a group of women (N=147) and men (N=385) who were currently in training for athletic competition. The control group consisted of women (N=262) and men (N=435) who were not and had never been competitive athletes. The “O-P” Attitude Questionnaire was used to measure optimism, while health behavior was measured with the Juczynski Health Behavior Inventory, which measures proper nutrition habits, preventive behavior, positive attitude, and healthy practices. Results The level of pessimism in these athletes was average. The female athletes were less pessimistic than the female controls. A similar, highly significant difference occurred between the male athletes and non-athletes. Gender did not differentiate the level of optimism in either group. Among the women, optimism correlated with healthy practices, such as daily sleep and recreation habits, or physical activity. The greater the pessimism increased, positive attitudes declined in the female controls, the female athletes, and the male controls. Conclusions The athletes displayed greater optimism than the controls. Among the women, optimism correlated with good health practices. PMID:22207118

    The inhibitory effect of menaquinone-7 (MK-7; vitamin K2) on osteoclast-like cell formation and osteoclastic bone resorption in vitro is found (Mol Cell Biochem 228: 39-47, 2001). This study, furthermore, was undertaken to determine the effect of MK-7 on the bone-resorbing factor-induced bone resorption using the femoral-diaphyseal and -metaphyseal tissues obtained from elderly female rats in vitro. Femoral-diaphyseal and -metaphyseal tissues were cultured for 48 h in Dulbecco's modified Eagle's medium (high glucose, 4.5%) supplemented with antibiotics and bovine serum albumin. The experimental cultures contained MK-7 (10(-7)-10(-5) M). The bone-resorbing factors, parathyroid hormone (1-34) (PTH; 10(-7) M) and prostaglandin E2 (PGE2; 10(-5) M), caused a significant decrease in calcium content in the diaphyseal and metaphyseal tissues. The PTH or PGE2-induced decrease in bone calcium content was completely inhibited in the presence of MK-7 (10(-7)-10(-5) M). In addition, MK-7 (10(-7)-10(-5) M) completely prevented the PTH (10(-7) M)- or PGE2 (10(-5) M)-induced increase in medium glucose consumption and lactic acid production by bone tissues. These results support the view that MK-7 has a direct inhibitory effect on the bone-resorbing factor-induced bone resorption in bone culture using female aged femoral tissues in vitro.

    Maternal malnutrition lead to the incidence of metabolic diseases in offspring. The purpose of this project was to exam whether maternal low chromium could disturb normal lipid metabolism in offspring, altering adipose cell differentiation and leading the incidence of lipid metabolism diseases, including metabolic syndrome and obesity. Female C57BL mice were given a control diet (CD) or a low chromium diet (LCD) during the gestational and lactation periods. After weaning, offspring was fed with CD or LCD. The female offspring were assessed at 32 weeks of age. Fresh adipose samples from CD-CD group and LCD-CD group were collected. Genome mRNA were analyzed using Affymetrix GeneChip Mouse Gene 2.0 ST Whole Transcript-based Array. Differently expressed genes were analyzed based on Gene Ontology and KEGG pathway analysis database. Maternal low chromium irreversibly increased offspring body weight, fat pad weight, serum TG and TNF-α. Eighty-five genes increased and 109 genes reduced in the offspring adipose of the maternal low chromium group. According to KEGG pathway and String analyses, the PPAR signaling pathway may be a key controlled pathway related to the effect of maternal low chromium on female offspring. Maternal chromium status have long-term effects of lipid metabolism in female mice offspring. Normalizing offspring diet can't reverse these effects. The potential underlying mechanisms are the disturbance of the PPAR signaling pathway in adipose tissue.

    2015-12-01

    To test the hypothesis that daily weight-making is more problematic to health in male compared with female jockeys, we compared the bone density and resting metabolic rate (RMR) in weight-matched male and female Flat jockeys. RMR (kcal·kg(-1) lean mass) was lower in males compared with females as well as lower bone-density Z scores at the hip and lumbar spine. Data suggest the lifestyle of male jockeys compromise health more severely than females, possibly because of making weight more frequently.

  4. Overtraining and elite young athletes.

    PubMed

    Winsley, Richard; Matos, Nuno

    2011-01-01

    In comparison to adults, our knowledge of the overtraining syndrome in elite young athletes is lacking. The evidence indicates an incidence rate of ∼20-30%, with a relatively higher occurrence seen in individual sport athletes, females and those competing at the highest representative levels. The most commonly reported symptoms are similar to those observed in over trained adult athletes: increased perception of effort during exercise, frequent upper respiratory tract infections, muscle soreness, sleep disturbances, loss of appetite, mood disturbances, shortness of temper, decreased interest in training and competition, decreased self-confidence, inability to concentrate. The association between training load and overtraining is unclear, and underlines the importance of taking a holistic approach when trying to treat or prevent overtraining in the young athlete so that both training and non-training stressors are considered. Of particular relevance to the issue of overtraining in the elite young athlete are the development of a unidimensional identity, the lack of autonomy, disempowerment, perfectionist traits, conditional love, and unrealistic expectations. Overtraining syndrome is a complex phenomenon with unique and multiple antecedents for each individual; therefore, an open-minded and comprehensive perspective is needed to successfully treat/prevent this in the young athlete.

    2014-01-01

    Osteoarthritis (OA) is one of the most devastating chronic conditions that affect people around the world. Although the usual population associated with the condition is the elderly, who are mostly inactive, athletes and younger individuals are also susceptible. Depending on the population, the etiology may differ; injuries, occupational activities, and obesity appear to be the most common causes of OA in young and athletic populations. Diagnosing OA in athletes and young individuals is sometimes challenging because of their increased pain tolerance. However, the treatment of OA in these populations does not differ from its management in the general population. Several considerations need to be taken into account when choosing a treatment modality. The purpose of this review is to address OA in athletes and younger individuals and to discuss its presentation, diagnosis, and treatment. PMID:24899825

    2014-01-01

    A report from panel members appointed to the Eighth Joint National Committee titled "2014 Evidence-Based Guideline for the Management of High Blood Pressure in Adults" has garnered much attention due to its major change in recommendations for hypertension treatment for patients ≥60 years of age and for their treatment goal. In response, certain groups have opposed the decision to initiate pharmacologic treatment to lower blood pressure (BP) at systolic BP ≥150 mm Hg and treat to a goal systolic BP of <150 mm Hg in the general population age ≥60 years. This paper contains 3 sections–an introduction followed by the opinions of 2 writing groups–outlining objections to or support of maintaining this proposed strategy in certain at-risk populations, namely African Americans, women, and the elderly. Several authors argue for maintaining current targets, as opposed to adopting the new recommendations, to allow for optimal treatment for older women and African Americans, helping to close sex and race/ethnicity gaps in cardiovascular disease morbidity and mortality.

    This paper investigates whether childhood conditions affect survival and health, both directly and indirectly through the mediating variable of adulthood socioeconomic status, among Chinese elderly. Using data from the 2008–2009 and 2011–2012 waves of the Chinese Longitudinal Healthy Longevity Survey, we apply structural equation models to estimate these effects. We find that favorable childhood conditions exert a negative direct impact on survival probability at senior ages, possibly resulting from mortality selection. Our results also support the pathways model, which indicates that advantageous childhood conditions improve socioeconomic status in adulthood and thus indirectly promote longevity and health at advanced ages. Combining the direct and indirect effects, the total effects of childhood advantages on survival and health are positive. We further demonstrate that direct and indirect effects of childhood conditions are stronger for women than they are for men. Our findings suggest that public policies that target childhood wellbeing may have far-reaching protective impacts on health among seniors. PMID:25007734

    A previously healthy 74-year-old Japanese female was hospitalized with fever and high C-reactive protein. She developed palatal herpangina-like aphthous ulcers, localized intestinal wall thickening, terminal ileum ulcers, and an erythematous acneiform rash; thus Behçet's disease-like illness was suspected. Significant peripheral blood acute monocytosis developed during her hospitalization and acute monocytic leukemia (FAB M5b) with normal karyotype was diagnosed. By immunostaining, the infiltrating cells in the skin and the terminal ileum were identified as monocytic leukemic cells. This case exhibited a unique initial presentation of Behçet's disease-like illness associated with acute monocytic leukemia. PMID:27610252

    The purpose of this study was to examine the career planning of university student athletes and relationships between their career planning and athletic and student role identities. Two retrospective in-depth interviews were held with four male and four female university student athletes. Participants entered university with vague or nonexistent career objectives and invested heavily in their athletic roles. In the latter years of their college career, the participants discarded their sport career ambitions and allowed the student role to become more prominent in their identity hierarchies. The current findings support Brown and Hartley's (1998) suggestion that student athletes may invest in both the athlete and student role identities simultaneously and that investing in the latter may permit the exploration of nonsport career options.

    The aim of the research was to determine construct validity and reliability for two questionnaires (Athlete Engagement Questionnaire-AEQ and Athletic Identity Measurement Scale-AIMS), applied on elite Croatian athletes-sprinters, as well as the correlations among the dimensions in these measuring instruments. Then, we have determined the differences in the dimensions of sport engagement and sport identity, according to gender, education level and winning medals on international competitions. A total of 71 elite athletes-sprinters (former and still active) are examined, from which 27 (38%) females and 44 (62%) males. The results of factor analyses revealed the existence of dimensions very similar as in the original instruments, which showed moderate to-high reliabilities. A small number of statistically significant correlations have been found between the dimensions of sport engagement and sport identity, mainly in male sprinter runners. Small number of statistically significant differences in the dimensions of sport engagement and sport identity have been found according to the gender, education level and winning medals on the international competitions. The most reasonable explanation of these differences could be given in terms of very similar characteristics of elite athletes on the same level of sport excellence.

    BACKGROUND/OBJECTIVES Athletes generally desire changes in body composition in order to enhance their athletic performance. Often, athletes will practice chronic energy restrictions to attain body composition changes, altering their energy needs. Prediction of resting metabolic rates (RMR) is important in helping to determine an athlete's energy expenditure. This study compared measured RMR of athletic and non-athletic adolescents with predicted RMR from commonly used prediction equations to identify the most accurate equation applicable for adolescent athletes. SUBJECTS/METHODS A total of 50 athletes (mean age of 16.6 ± 1.0 years, 30 males and 20 females) and 50 non-athletes (mean age of 16.5 ± 0.5 years, 30 males and 20 females) were enrolled in the study. The RMR of subjects was measured using indirect calorimetry. The accuracy of 11 RMR prediction equations was evaluated for bias, Pearson's correlation coefficient, and Bland-Altman analysis. RESULTS Until more accurate prediction equations are developed, our findings recommend using the formulas by Cunningham (-29.8 kcal/day, limits of agreement -318.7 and +259.1 kcal/day) and Park (-0.842 kcal/day, limits of agreement -198.9 and +196.9 kcal/day) for prediction of RMR when studying male adolescent athletes. Among the new prediction formulas reviewed, the formula included in the fat-free mass as a variable [RMR = 730.4 + 15 × fat-free mass] is paramount when examining athletes. CONCLUSIONS The RMR prediction equation developed in this study is better in assessing the resting metabolic rate of Korean athletic adolescents. PMID:26244075

    Stress-induced cardiomyopathy (SIC), also known as takotsubo cardiomyopathy (TTC), is a relatively newly-described condition, which has been increasingly reported in the literature. It is characterized by acute onset of symptoms and electrocardiogram changes mimicking myocardial infarction, with transient but completely reversible left ventricular (LV) dysfunction. SIC commonly occurs following physical or emotional stress. The present study discusses the case of a 68-year-old female patient who had suffered from infection of the upper respiratory tract for 10 days before admission to the hospital with symptoms of chest stuffiness and dyspnea that persisted for 2 days. Coronary angiography showed normal coronary artery function, while LV angiography demonstrated systolic apical ballooning. Based on these observed characteristics, the patient was diagnosed with SIC and was successfully treated. PMID:27882121

    [Purpose] This study examined the effects of exercise training on bone metabolism markers, inflammatory markers, and physical fitness in patients with osteoporosis from an osteoporosis-related immunological perspective. [Subjects and Methods] Twenty-nine elderly female subjects (age, 74.2 ± 3.2 years) were classified into normal, osteopenia, and osteoporosis groups based on the T-score measured using dual-energy X-ray absorptiometry. The exercise was performed voluntarily by the patients for 1 hour per day, three times per week, for 12 weeks. [Results] The differences between bone mineral content, bone mineral density, and osteocalcin concentrations increased significantly in the osteoporosis group after 12 weeks of exercise and were significantly higher than those in the normal and osteopenia groups. However, the homeostatic model assessment of insulin resistance score decreased significantly in the osteoporosis group after 12 weeks of exercise. High-sensitivity C-reactive protein concentrations tended to decrease in all groups after 12 weeks of exercise and showed an inverse correlation with osteocalcin concentration; however, no statistical significance was observed. [Conclusion] Our findings suggest that an exercise program in patients with osteopenia and osteoporosis effectively reduces the risk of osteoporotic fracture and related diseases since it improves bone density and physical fitness and reduces inflammatory marker levels.

  18. Minerals: exercise performance and supplementation in athletes.

    PubMed

    Clarkson, P M

    1991-01-01

    This paper examines whether mineral supplements are necessary for athletes, and whether these supplements will enhance performance. Macrominerals (calcium, magnesium, and phosphorus) and trace minerals (zinc, copper, selenium, chromium, and iron) are described. Calcium supplements are important for the health of bones. Athletes tend to have enhanced calcium status as assessed by bone mineral density, with the notable exception of female amenorrhoeic athletes. Magnesium status is adequate for most athletes, and there is no evidence that magnesium supplements can enhance performance. Phosphorus status is adequate for athletes. Phosphorus supplementation over an extended period of time can result in lowered blood calcium, however, some studies have shown that acute 'phosphate loading' will enhance performance. Athletes may have a zinc deficiency induced by poor diet and loss of zinc in sweat and urine. Limited data exist on the relationship of performance and zinc status. Widespread deficiencies in copper have not been documented, and there are no data to suggest that copper supplementation will enhance performance. There is no reason to suspect a selenium deficiency in athletes. The relationship between selenium status and performance has not been established, but selenium may play a role as an antioxidant. Because of the low intakes of chromium for the general population, there is a possibility that athletes may be deficient. Exercise may create a loss in chromium because of increased excretion into the urine. Many athletes, particularly female, are iron depleted, but true iron deficiencies are rare. Iron depletion does not affect exercise performance but iron deficiency anaemia does. Iron supplements have not been shown to enhance performance except where iron deficiency anaemia exists. In conclusion, poor diets are perhaps the main reason for any mineral deficiencies found in athletes, although in certain cases exercise could contribute to the deficiency. Mineral

    To investigate whether aquatic athletes follow optimal dietary intake, 58 athletes, all members of the Greek national swimming and water polo teams, were tested. Dietary intake was assessed at the nutrient, food, and food group level using the 24-h recall method and a food frequency questionnaire. Mean energy intake for males and females was 14.3 and 8.5 MJ, respectively. Mean carbohydrate consumption for male and female athletes was 4.5 g/kg and 3.8 g/kg of body weight, respectively. Fat intake was 153 g for males and 79 g for females. A significant number of the athletes (71% of the males, 93% of the females) did not meet the Dietary Reference Intakes for at least one of the antioxidant vitamins. The data suggest that athletes of both genders consumed too much fat and too little carbohydrate. Insufficient fruit and vegetable intake was related to low intake of antioxidants.

    2006-01-01

    The aim of the study was to present the prevalence of clinical signs and symptoms among female computer users above 45 years, both in a group with self-reported neck/shoulder trouble (NS cases) and in a group without such trouble (NS controls). The hypothesis was that computer users with self-reported neck/shoulder trouble have more clinical findings than those not reporting trouble, and that a corresponding pattern holds true for physical function. In total 42 and 61 questionnaire-defined NS cases and NS controls participated and went through a clinical examination of the neck and upper extremities and five physical function tests: maximal voluntary contraction (MVC) of shoulder elevation, abduction, and handgrip, as well as endurance at 30% MVC shoulder elevation and a physical performance test. Based on clinical signs and symptoms, trapezius myalgia (38%), tension neck syndrome (17%) and cervicalgia (17%) were the most frequent diagnoses among NS cases, and were significantly more frequent among NS cases than NS controls. A total of 60% of the subjects with reported trouble had one or several of the diagnoses located in the neck/shoulder. Physical function of the shoulder was lower in subjects with self-reported trouble as well as in the subgroup of NS cases with clinical diagnoses. In conclusion, the present clinical diagnoses and physical function tests differed between NS cases and NS controls, and are therefore recommended to be included as quantitative objective measures in assessing musculoskeletal health. Physical function tests should be further developed in order to be able to detect pre-stages of work-related disorders for preventive strategies.

    Background Paying attention to and improving the mental health of the informal caregivers of disabled elders has become a global public health priority. This study focused on low-income female Uyghur and Kazakh informal caregivers of disabled elders residing in China’s far west. It investigated the prevalence of and the major related factors of depressive emotion. Methods A cross-sectional study was performed from September 2013 to January 2014 in Shawan Prefectures, Tuokexun Prefectures, Bole Prefecture and Urumchi city. Shawan Prefecture has the highest proportion of Kazakhs, whereas Tuokexun Prefectures, Bole Prefecture and Urumchi city have the highest proportion of Uyghurs in Muslim ethnic Uygur and Kazakh communities. Xinjiang Uyghur Autonomous Region is located in remote western China; this area is approximately 3,105 km (1,929 miles) away from Beijing. A total of 444 female Uyghur and Kazakh informal caregivers of disabled elders participated in this study. The self-rating depression scale, the Zarit burden interview, and the SF-36 questionnaire were used to evaluate the state of caregiver depression, caregiver burden, and quality of life (QOL), respectively. Statistical analyses were performed using multivariate logistic regression analyses, correlation with Spearman’s rho and independent-sample t-tests; a P-value of <0.05 was considered statistically significant. Results Up to 38.5% (n = 217) of informal caregivers reported having depression, whereas 61.5% (n = 273) of them reported a lack of depression. Age of disabled elders more than 60 years old, total hours spent on caring daily≥8h, duration of caring≥5 years, negative self-evaluation of health condition, having caregiver burden, elders’ medium degree of disability and elders’ heavy degree of disability had a higher risk of caregiver depression. By contrast, daughter/daughter-in-law of disabled elders; unemployed carers, family’s per capita income >US$235.48(1500 yuan), high social

    Objective: To compare bone mineral density (BMD), investigate factors associated with BMD, and examine the prevalence of low BMD in athletes and non-athletic controls. Methods: The study included a questionnaire (part I), measurement of BMD (part II), and a clinical interview (part III). All Norwegian female athletes on national teams (n = 938) and an aged matched random sample of non-athletic controls (n = 900) were invited to participate. The questionnaire was completed by 88% of athletes and 70% of controls. A random sample of these athletes (n = 300) and controls (n = 300) was invited to participate in parts II and III. All parts were completed by 186 athletes (62%) and 145 controls (48%). Results: Mean (standard deviation) total body (TB) BMD was higher (p<0.001) in athletes (1.21 (0.09) g/cm2) than in controls (1.18 (0.08) g/cm2), and higher (p<0.001) in high impact (HI) sports athletes than in medium impact (MI) and low impact (LI) sports athletes. In athletes, body weight and impact loading sports were positively associated, and percent body fat and eating disorders were negatively associated with TB BMD. Body weight and weight bearing activities were positively associated and menstrual dysfunction was negatively associated with TB BMD in controls. A higher percentage of controls (28.3%) than athletes (10.7%) had low BMD (p<0.001). Conclusion: Female elite athletes have 3–20% higher BMD than non-athletic controls and HI sports athletes have 3–22% higher BMD compared with MI and LI sports athletes. Low BMD is two to three times more common in non-athletic premenopausal women than in elite athletes. PMID:15849292

    There is no methodological standardization of velocity thresholds for the quantification of distances covered in various locomotor activities for women's soccer matches, especially for high-speed running and sprinting. Applying velocity thresholds used for motion analysis of men's soccer has likely created skewed observations about high-intensity movement demands for the women's game because these thresholds do not accurately reflect the capabilities of elite female players. Subsequently, a cohesive view of the locomotor characteristics of women's soccer does not yet exist. The aim of this commentary is to provide suggestions for standardizing high-speed running and sprint velocity thresholds specific to women's soccer. The authors also comment on using generic vs individualized thresholds, as well as age-related considerations, to establish velocity thresholds.

    Two of the most popular forms of protein on the market are whey and casein. Both proteins are derived from milk but each protein differs in absorption rate and bioavailability, thus it is possible that each type of protein may contribute differently to the adaptations elicited through resistance training. Therefore, the purpose of this study was to investigate the potential effects of ingestion of two types of protein in conjunction with a controlled resistance training program in collegiate female basketball players. Sixteen NCAA Division III female basketball players were matched according to body mass and randomly assigned in a double-blind manner to consume 24 g whey protein (WP) (N = 8, 20.0 ± 1.9 years, 1.58 ± 0.27 m, 66. 0 ± 4.9 kg, 27.0 ± 4.9 %BF) or 24 g casein protein (CP) (N = 8, 21.0 ± 2.8 years, 1.53 ± 0.29 m, 68.0 ± 2.9 kg, 25.0 ± 5.7 %BF) immediately pre- and post-exercise for eight weeks. Subjects participated in a supervised 4-day per week undulating periodized training program. At 0 and 8 weeks, subjects underwent DXA body composition analysis, and at 0 and 8 weeks underwent one repetition maximum (1RM) strength, muscle endurance, vertical jump, 5-10-5 agility run, and broad jump testing sessions. Data were analyzed using repeated measures ANOVA, and presented as mean ± SD changes from baseline after 60 days. No significant group x time interaction effects were observed among groups in changes in any variable (p > 0.05). A significant time effect was observed for body fat (WP: -2.0 ± 1.1 %BF; CP: -1.0 ± 1.6 %BF, p < 0.001), lean mass (WP: 1.5 ± 1.0 kg; CP: 1. 4 ± 1.0 kg, p < 0.001), fat mass (WP: -1.3 ± 1.2 kg; CP: -0.6 ± 1.4 kg, p < 0.001), leg press 1RM (WP: 88.7 ± 43.9 kg; CP: 90.0 ± 48.5 kg, p < 0.001), bench press 1RM (WP: 7.5 ± 4.6 kg; CP: 4.3 ± 4.5 kg, p = 0.01), vertical jump (WP: 4.1 ± 1.8 cm; CP: 3.5 ± 7.6 cm, p < 0.001), 5-10-5 (WP: -0.3 ± 0.2 sec; CP: -0.09 ± 0.42 sec, p < 0.001), and broad jump (WP: 10.4 ± 6

    College students experience higher rates of gambling-related problems than most other population segments, including the general population. Although Division I (D1) athletes often have more at stake than the average student if and when they gamble (e.g., the potential to lose their athletic eligibility), relatively few studies have assessed the gambling behavior of this population and none have specifically assessed fantasy sports gambling. We conducted a study to examine gambling behavior (past-year gambling, gambling-related problems, and fantasy sport gambling) among a sample (N = 692) of college students at a private religiously affiliated university in the Southwest US. The sample for our study was unique in that approximately 30 % of the participants were D1 athletes. We compared the gambling behavior among three groups based on the athlete status: D1 athletes, club/intramural/recreational (CIR) athletes, and non-athletes (NAs). Compared to females in our sample, males observed higher rates of past year gambling, fantasy sports participation, fantasy sports gambling, and gambling-related problems. Among males, we found that CIR athletes observed the highest rates of past year gambling and fantasy sports participation and D1 athletes observed higher rates than NAs. We did not find differences in fantasy sport gambling and past year gambling-related problems based on athlete status in males or females.

    We aimed to describe the relationship between BMI and the subcutaneous adipose tissue topography within young athletes and non-athletic controls, to comparatively evaluate the diagnostic powers of subcutaneous adipose tissue thicknesses at different body sites, furthermore to explore appropriate cut-offs to discriminate between athletes and controls. Measurements were determined in 64 males and 42 females, who were subsequently separated into two even groups (athletes and non-athletes). The optical device LIPOMETER was applied at standardised body sites to measure the thickness of subcutaneous adipose tissue layers. To calculate the power of the different body sites and the BMI to discriminate between athletes and non-athletes, receiver operating characteristic curve analysis was performed. In men, the neck (optimal cut-off value 2.3 mm) and trunk (optimal cut-off value 15.5 mm) provided the strongest discrimination power: with 90.6% (58 of 64) of the subjects being correctly classified into athletes or non-athletes. Discrimination power of the BMI values was 64.1% (41 of 64 were correctly classified). In women, the upper back (optimal cut-off value 3.3 mm) and arms (optimal cut-off value 15.9 mm) provided the strongest discrimination power with 88.1% (37 of 42 being correctly classified). When using BMI to discriminate between athletes and non-athletes only 52.4% (22 of 42) were correctly classified. These results suggest that compared to BMI levels, subcutaneous fat patterns are a more accurate way of discriminating between athletes and non-athletes. In particular the neck and the trunk compartment in men and the upper back and arms compartment in women, were the best sites to discriminate between young athletes and non-athletes on the basis of their fat patterns.

    The purpose of this study was to examine epidemiological trends of concussions among 15 different intercollegiate sports during the 1997-1998, 1998-1999, and 1999-2000 seasons. Data were collected using the National Collegiate Athletic Association (NCAA) Injury Surveillance System (ISS). For the 15 sports studied during the 3 academic years, the NCAA ISS documented 3,535 team-seasons, 40,547 reportable injuries, 5,566,924 practice athlete exposures (AEs), and 1,090,298 game AEs. Concussions accounted for 6.2% of all reported injuries during this 3-year study. Of all the reported injuries, women lacrosse players (13.9%) reported the highest percentage of suffering a concussion during a game followed by women's soccer (11.4%), men's ice hockey (10.3%), men's lacrosse (10.1%), football (8.8%), women's basketball, (8.5%), field hockey (7.2%), men's soccer (7.0%), wrestling (6.6%), men's basketball (5.0%), baseball (4.2%), and women's volleyball (4.1%). Female athletes from all 7 sports were found to be at a lower risk for suffering concussions during practice sessions than the 8 male sports. However, female athletes were found to be at a greater risk for suffering concussions during games compared to male athletes. Injury trends over the 3- year period indicate concussions continue to be on the rise for athletes participating in collegiate football, men's soccer, and women's and men's basketball.

    Despite a proliferation of research on disordered eating in female athletes, few studies have included male athletes. The purpose of this study was to determine which of five personality and psychological variables of interest (i.e., perfectionism, self-esteem, optimism, reasons for exercise, and appearance orientation) best predicted eating disorder status (i.e., symptomatic or asymptomatic) in male athletes. Two hundred three male athletes (Mage=20.29, SD=1.64) from three National Collegiate Athletic Association (NCAA) Division I institutions participated. More athletes were asymptomatic (80.8%) than symptomatic (19.2%). None of the variables significantly predicted symptomatic status. These findings contrast the literature on predictors of disordered eating symptomatology among female athletes, and suggest the need for further research to identify other potential predictors of eating disturbance among male athletes.

    Background Although Perceived Stress Scale (PSS, Cohen, Kamarack & Mermelstein, 1983) has been validated and widely used in many domains, there is still no validation in sports by comparing athletes and non-athletes and examining related psychometric indices. Purpose The purpose of this study was to examine the measurement invariance of PSS between athletes and non-athletes, and examine construct validity and reliability in the sports contexts. Methods Study 1 sampled 359 college student-athletes (males = 233; females = 126) and 242 non-athletes (males = 124; females = 118) and examined factorial structure, measurement invariance and internal consistency. Study 2 sampled 196 student-athletes (males = 139, females = 57, Mage = 19.88 yrs, SD = 1.35) and examined discriminant validity and convergent validity of PSS. Study 3 sampled 37 student-athletes to assess test-retest reliability of PSS. Results Results found that 2-factor PSS-10 fitted the model the best and had appropriate reliability. Also, there was a measurement invariance between athletes and non-athletes; and PSS positively correlated with athletic burnout and life stress but negatively correlated with coping efficacy provided evidence of discriminant validity and convergent validity. Further, the test-retest reliability for PSS subscales was significant (r = .66 and r = .50). Discussion It is suggested that 2-factor PSS-10 can be a useful tool in assessing perceived stress either in sports or non-sports settings. We suggest future study may use 2-factor PSS-10 in examining the effects of stress on the athletic injury, burnout, and psychiatry disorders. PMID:27994983

    The present study examined the activity profile, heart rate and metabolic response of small-sided football games for untrained males (UM, n=26) and females (UF, n=21) and investigated the influence of the number of players (UM: 1v1, 3v3, 7v7; UF: 2v2, 4v4 and 7v7). Moreover, heart rate response to small-sided games was studied for children aged 9 and 12 years (C9+C12, n=75), as well as homeless (HM, n=15), middle-aged (MM, n=9) and elderly (EM, n=11) men. During 7v7, muscle glycogen decreased more for UM than UF (28 +/- 6 vs 11 +/- 5%; P<0.05) and lactate increased more (18.4 +/- 3.6 vs 10.8 +/- 2.1 mmol kg(-1) d.w.; P<0.05). For UM, glycogen decreased in all fiber types and blood lactate, glucose and plasma FFA was elevated (P<0.05). The mean heart rate (HR(mean)) and time >90% of HR(max) ranged from 147 +/- 4 (EM) to 162 +/- 2 (UM) b.p.m. and 10.8 +/- 1.5 (UF) to 47.8 +/- 5.8% (EM). Time >90% of HR(max) (UM: 16-17%; UF: 8-13%) and time spent with high speed running (4.1-5.1%) was similar for training with 2-14 players, but more high-intensity runs were performed with few players (UM 1v1: 140 +/- 17; UM 7v7: 97 +/- 5; P<0.05): Small-sided games were shown to elucidate high heart rates for all player groups, independently of age, sex, social background and number of players, and a high number of intense actions both for men and women. Thus, small-sided football games appear to have the potential to create physiological adaptations and improve performance with regular training for a variety of study groups.

    Context Many athletes fail to obtain the optimal levels of energy and nutrients to support health and performance. The constructs underlying the Theory of Planned Behavior (TPB) may help identify barriers to healthful eating that can be addressed in nutrition-education programs. Objective To use the TPB to examine factors regarding collegiate male and female student-athletes' intentions of eating a healthful diet. Design Cross-sectional study. Setting Online survey tool. Patients or Other Participants The survey was taken by 244 male and female National Collegiate Athletic Association Division II athletes, and data from 201 were analyzed. Mean age of the athletes was 20 ± 1.31 years (range, 18–24 years); most were white (86.1%) and female (78.6%). Main Outcome Measure(s) We assessed predictive strength of attitude, subjective norms, and perceived behavioral control on behavioral intentions. Regression analysis evaluated how the variables of TPB were valued and how they predict behavioral intentions. Results The combination of attitude, subjective norms, and perceived behavioral controls accounted for 73.4% (R 2) of the variance in behavioral intention (F = 180.82, P < .001). Attitude had the greatest influence on behavioral intentions (β = .534, P < .001). Conclusions Understanding both the intentions of collegiate athletes to eat healthfully and how highly they value nutrition is crucial for the development of effective nutrition education and counseling programs.

    Dietary supplement (DS) intake is high in elite level athletes, however few studies have investigated the impact that the performance level of the athletes has on supplementation intake in individual and team sports. The purpose of the study was to determine and compare the DS intake among individual and team sport athletes of various performance levels. A total of 2845 participants (athletes: 2783, controls: 62) between the ages of 11 and 44 years old participated in the study. A 3-page questionnaire was developed to assess the intake of DS. Athletes were categorized based on participation in individual (n = 775) and team sports (n = 2008). To assess the effect of performance level in supplementation intake, athletes were categorized based on training volume, participation in the national team, and winning at least one medal in provincial, national, international or Olympic games. Overall, 37% of all athletes of various performance levels reported taking at least one DS in the last month. A higher prevalence of DS intake was reported in individual (44%) compared to team sport athletes (35%) (p < 0.001). Athletes of high performance level reported greater DS intake compared to lower performance athletes. Males reported a significantly greater prevalence of DS intake compared to females. The most popular supplement reported was amino acid preparation with the main reason of supplementation being endurance improvements. In conclusion, performance level and type of sport appear to impact the DS practices of male and female athletes. These findings should be validated in other populations. Key points37% of Mediterranean athletes of various sports and levels have reported taking dietary supplements.The performance level of the athletes affects the dietary supplementation intake.Athletes in individual sports appear to have a higher DS intake compared to team sport athletes.Male athletes appear to take more dietary supplements compared to female athletes.

    The study investigated the coaching preferences of 95 male and 65 female elite athletes competing at Universiade '83 (Edmonton, Canada). Preferred coaching behaviour (PCB) was measured using a version of the Leadership Scale for Sports (Chelladurai and Saleh, 1978, 1980). Preference scores were analyzed on the basis of sex, age, nationality, and type of sport. A MANOVA indicated that males prefer significantly more Autocratic behaviour than females (p = .039). Also, athletes in team sports prefer significantly more Training behaviour (p = .001), Autocratic behaviour (p less than .001), and Rewarding behaviour (p = .017), and significantly less Democratic behaviour (p less than .001) and Social Support behaviour (p = .002) than athletes in individual sports. No significant differences in PCB attributable to the age or nationally of the athlete were found. In addition, data collected in a previous study (Terry and Howe, 1984), which examined the PCB of 'club' athletes, was included to facilitate a comparison of club v elite athletes. A MANOVA showed that elite athletes prefer significantly more Democratic behaviour (p = .01) and Social Support behaviour (p = .001), and significantly less Rewarding behaviour (p = .01) than athletes at a 'club' level. Although differences between subject groups were found, it can be concluded that athletes generally tend to favour coaches who "often" display Training behaviour and Rewarding behaviour, "occasionally" display Democratic behaviour and Social Support behaviour, and "seldom" display Autocratic behaviour.

  7. Clinical observations from nutrition services in college athletics.

    College athletes are vulnerable to nutritional risks because of the rigorous demands of their sport, and because of the realities of college lifestyles. Athletes often adopt rigid training diets that predispose them to undernutrition, fatigue, and injury. Disordered eating, a common concern for college-aged women, affects a substantial number of female collegiate athletes, and is a growing concern for their male counterparts. Few resources exist to promote nutritional well-being among college athletes, particularly for individuals who suffer from eating pathology that is subclinical and often perceived as benign. This article presents evidence of the need for nutrition services for college athletes and describes nutritional risks that affect individuals across a variety of athletic teams. A multidisciplinary treatment model is depicted, featuring a nutrition practice at the core of a sports medicine wellness program in Division I college athletics. Observations from this practice document a substantial burden of subclinical eating disorders and elucidate characteristics of high-risk individuals. The Female Athlete Screening Tool is advocated as a useful tool for identifying eating pathology and triggering timely interventions. These insights from clinical practice identify opportunities and behavioral targets for intervention, and promote an effective model for health promotion in college athletics.

    Poomsae is the only non-contact and no opponent form of Taekwondo. The purpose of this descriptive study was to determine the type and rate of injuries in elite Canadian Poomsae athletes. Strain and joint dysfunction were the most common types of injuries in Poomsae. Lower limb and back were the most common area of injury in females and males respectively. Females with a lower rank in experience level (DAN≤ 3) were more likely to suffer from chronic overuse injuries compared to their male counterparts, who reported more acute injuries. Athletes ≤40 years of age were more prone to acute injuries compared to athletes over 40. As result of reflection on this study a Poomsae Injury Report Form was developed.

    We present a case of successful and uncomplicated total hip arthroplasty with an acetabular reinforcement device in an elderly patient with hip osteoarthritis already diagnosed with factor XI deficiency, which is a very rare bleeding disorder and at high risk of post-operative haemorrhage, and it poses a substantial challenge to surgeons as a consequence of the specific risks of infection and fixation failure. Moreover, bone fragility in elderly patient increases potential risk of adverse event. Fresh frozen plasma was used to supplement factor XI activity. Importantly, transfusion-transmitted disease such as having factor XI inhibitor was promptly surveyed prior to the supplement since the patient had previous history of the administration of fresh frozen plasma. Under prompt and effective peri-operative haemostasis, rigid implant fixation and rigorous attention to the prevention of infection seem to achieve the best possible outcomes for elderly patients with a bleeding disorder undergoing total hip arthroplasty.

    Supplements have become a staple with athletes. Athletes take supplements to enhance their performance through replenishment of real and perceived deficiencies, anabolic action of stimulants, increased energy and alertness, and for weight control. Physicians who deal with athletes should be aware of the supplements being utilized by athletes, the athletes' desired effects and the efficacy of the supplement, the adverse effects, and whether the supplement is banned by leagues or organizations in which the athletes are competing. For those athletes who are regularly drug tested for performance enhancers, it is important to remember that one cannot be 100% sure that any supplement will not result in a positive drug test, because there is no independent agency certifying purity.

    2015-11-01

    Objetivo: determinar la ingesta de macronutrientes adecuada para mejorar el estado nutricional de las mujeres atletas y su rendimiento deportivo. Métodos: se realizó una búsqueda en cuatro bases de datos: EBSCO, Proquest, Pubmed y OvidSP, empleando las palabras clave “protein intake” AND “athletes” y “endurance athletes” AND “nutrition”. Criterios de selección: artículos originales sobre el consumo de proteínas en atletas femeninas (Entre 2009 y 2014), en revistas científicas indexadas. Resultados: se identificaron 722 artículos, de los cuales solo el 1,4% fueron considerados como incluidos. El 100% eran ensayos clínicos finalizados y publicados en el extranjero, el 50% en EE. UU. El 20% eran estudios exclusivos de mujeres atletas y el 80% incluían hombres y mujeres en la muestra. En el 70% de los estudios las mujeres atletas presentaron déficits energéticos; en la ingesta proteica, el 70% cumplieron con las recomendaciones dietéticas; la ingesta de hidratos de carbono fue inadecuada en el 90% de los ensayos clínicos y, en el 50%, las mujeres presentaban una sobreingesta de grasas. Conclusiones: existe una deficiencia de información acerca de la nutrición en mujeres atletas en Europa y a nivel internacional. Las atletas femeninas consumen energía y macronutrientes en menor proporción que los atletas masculinos. No existe consenso en el rango de proteínas recomendado y se encuentran discrepancias en el consumo en función del tipo de ejercicio físico que se realice. Se recomienda llevar a cabo un acuerdo entre instituciones científicas de prestigio sobre la ingesta energética y de macronutrientes en el deporte, especialmente en la mujer.

  5. Somatotype, training and performance in Ironman athletes.

    PubMed

    Kandel, Michel; Baeyens, Jean Pierre; Clarys, Peter

    2014-01-01

    The aim of this study was to describe the physiques of Ironman athletes and the relationship between Ironman's performance, training and somatotype. A total of 165 male and 22 female competitors of the Ironman Switzerland volunteered in this study. Ten anthropometric dimensions were measured, and 12 training and history variables were recorded with a questionnaire. The variables were compared with the race performance. The somatotype was a strong predictor of Ironman performance (R=0.535; R(2)=0.286; sign. p<0.001) in male athletes. The endomorphy component was the most substantial predictor. Reductions in endomorphy by one standard deviation as well as an increased ectomorphy value by one standard deviation lead to significant and substantial improvement in Ironman performance (28.1 and 29.8 minutes, respectively). An ideal somatotype of 1.7-4.9-2.8 could be established. Age and quantitative training effort were not significant predictors on Ironman performance. In female athletes, no relationship between somatotype, training and performance was found. The somatotype of a male athlete defines for 28.6% variance in Ironman performance. Athletes not having an ideal somatotype of 1.7-4.9-2.8 could improve their performance by altering their somatotype. Lower rates in endomorphy, as well as higher rates in ectomorphy, resulted in a significant better race performance. The impact of somatotype was the most distinguished on the run discipline and had a much greater impact on the total race time than the quantitative training effort. These findings could not be found in female athletes.

    Since 1961, Special Olympics has provided sports training and athletic competition for people with mental retardation. A recent addition to these Olympics has been the Healthy Athletes Program, designed to help the athletes improve their health and fitness, leading to enhanced sports experiences and well being. Original health services included dental and eye screening. In 2002, Special Olympics Delaware piloted a Wellness Park to add nutrition, blood pressure, and flexibility screening. Faculty from a university's health college trained discipline-specific students to conduct the screenings. Thirty nutrition and dietetics students measured height, weight, waist circumference, and calculated body mass index (BMI) for the athletes. Figures and risk-assessments were recorded on a "health report card." Two hundred ten athletes attended the nutrition screening. Ages ranged from 8 to 63 years; 81 percent males and 19 percent females. According to BMI standards, 32 percent of the athletes were overweight; 17 percent were obese. Twenty-five percent of adult males and 73 percent of adult females had a high risk waist circumference. Athletes at high risk for obesity-related diseases were referred to their primary physician for follow up. Nutrition education handouts included a simplified Food Guide Pyramid, tips for healthy eating in restaurants, 5 A Day information, and healthful hydration guides. Approximately 1,250 athletes participate in Special Olympics Delaware each year, providing a great opportunity to do some much needed health screening and improve access to health care for this often neglected population.

  7. Reference intervals for serum creatine kinase in athletes

    PubMed Central

    Mougios, Vassilis

    2007-01-01

    Background The serum concentration of creatine kinase (CK) is used widely as an index of skeletal muscle fibre damage in sport and exercise. Since athletes have higher CK values than non‐athletes, comparing the values of athletes to the normal values established in non‐athletes is pointless. The purpose of this study was to introduce reference intervals for CK in athletes. Method CK was assayed in serum samples from 483 male athletes and 245 female athletes, aged 7–44. Samples had been obtained throughout the training and competition period. For comparison, CK was also assayed in a smaller number of non‐athletes. Reference intervals (2.5th to 97.5th percentile) were calculated by the non‐parametric method. Results The reference intervals were 82–1083 U/L (37°C) in male and 47–513 U/L in female athletes. The upper reference limits were twice the limits reported for moderately active non‐athletes in the literature or calculated in the non‐athletes in this study. The upper limits were up to six times higher than the limits reported for inactive individuals in the literature. When reference intervals were calculated specifically in male football (soccer) players and swimmers, a threefold difference in the upper reference limit was found (1492 vs 523 U/L, respectively), probably resulting from the different training and competition demands of the two sports. Conclusion Sport training and competition have profound effects on the reference intervals for serum CK. Introducing sport‐specific reference intervals may help to avoid misinterpretation of high values and to optimise training. PMID:17526622

  8. Psychological effects of chronic injury in elite athletes.

    Shuer, M L; Dietrich, M S

    1997-01-01

    Many athletes train in a constant state of pain or injury while meeting the demands of an elite level program. It is hypothesized that the emotional distress experienced by athletes with chronic injuries is not inconsequential. A self-report battery, the Impact of Event Scale, was administered to 280 inter-collegiate athletes at a division I institution in an attempt to examine their response to chronic injury. Of the 280, 134 (48%) had been injured by study definition, with 117 (42%) meeting the criteria for chronic injury. Athletes with chronic injury scored on the Intrusion subscale of the Impact of Event Scale in the range of those who had experienced natural disasters, but scored higher (P < .05) on the Avoidance/Denial subscale. Their Avoidance subscale scores were similar to those of a group of orthopedic patients who required hospital admission with surgical fixation. Female athletes' Avoidance scores were significantly higher than those of their male peers (P < .05), but no gender differences were seen in intrusive thoughts. Subsets of athletes defined by the duration of injury showed no significant differences on subscale scores. It appears extraordinary that athletes should score in the realm of groups traumatized by natural disasters in intrusive thought and higher in avoidance thought when referring to their chronic injury. Although some attention has been focused on psychiatric intervention for acutely injured athletes or those who have undergone surgical treatment, the psychological needs of athletes struggling with chronic "minor" injuries also appear to merit consideration.

    2006-10-01

    Although athletes' beliefs and values are known to influence whether or not an athlete will use banned drugs, little is known about the athletes' beliefs and attitudes in different sports. The aim of this study was to clarify the beliefs and attitudes of elite athletes towards banned substances and methods in sports. A total of 446 athletes (response rate 90.3 %; 446/494) financially supported by the National Finnish Olympic Committee completed a structured questionnaire during their national team camps in 2002. More than 90 % of the athletes reported to believe that banned substances and methods have performance enhancing effects, and 30 % reported that they personally know an athlete who uses banned substances. Of the male athletes 35 %, and 23 % of females reported they personally know an athlete using banned substances. A total of 15 % of the athletes reported that they had been offered banned substances: 21 % of the speed and power athletes, 14 % of the team sport athletes and of the athletes in motor skills demanding events, and 10 % of the endurance athletes. Stimulants were the most often offered substance group (to 7 % of all the athletes) followed by anabolic steroids (4 %). Subjects who regarded doping as a minor health risk seemed to be more often associated with doping users than those regarding doping as a significant health risk. Athletes in different sports have a different approach to doping. Risk of doping appears to be highest in speed and power sports and lowest in motor skills demanding sports. Males are at higher risk than females. Controlling doping only by tests is not sufficient. A profound change in the attitudes is needed, which should be monitored repeatedly.

    In general, painful feet can affect the performance of an athlete in any sport. To prevent skin diseases of the feet, the "Athlete's Foot" should be kept clean and dry with toenails trimmed. Properly fitting athletic shoes should be worn to avoid the formation of blisters. Wearing of sandals in locker and shower rooms, which prevents intimate contact with infecting organisms, can alleviate many of the problems that affect the feet.

    Attention-deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder that affects the child and adolescent population. It is characterized by impairment in attention/concentration, hyperactivity, and impulsivity, all of which can impact performance of athletes. ADHD treatment within the athletic population is a unique challenge. The research in this field has been relatively limited. The National Collegiate Athletic Association and International Olympic Committee both regulate the use of psychostimulants for treatment of ADHD due to their performance-enhancing effects. In this article, authors have discussed the screening methods, pharmacological treatment, side effects, and behavioral approaches for the treatment of ADHD in adolescent athletes. PMID:24987666

  14. Athletes at High Altitude

    Khodaee, Morteza; Grothe, Heather L.; Seyfert, Jonathan H.; VanBaak, Karin

    2016-01-01

    Context: Athletes at different skill levels perform strenuous physical activity at high altitude for a variety of reasons. Multiple team and endurance events are held at high altitude and may place athletes at increased risk for developing acute high altitude illness (AHAI). Training at high altitude has been a routine part of preparation for some of the high level athletes for a long time. There is a general belief that altitude training improves athletic performance for competitive and recreational athletes. Evidence Acquisition: A review of relevant publications between 1980 and 2015 was completed using PubMed and Google Scholar. Study Design: Clinical review. Level of Evidence: Level 3. Results: AHAI is a relatively uncommon and potentially serious condition among travelers to altitudes above 2500 m. The broad term AHAI includes several syndromes such as acute mountain sickness (AMS), high altitude pulmonary edema (HAPE), and high altitude cerebral edema (HACE). Athletes may be at higher risk for developing AHAI due to faster ascent and more vigorous exertion compared with nonathletes. Evidence regarding the effects of altitude training on athletic performance is weak. The natural live high, train low altitude training strategy may provide the best protocol for enhancing endurance performance in elite and subelite athletes. High altitude sports are generally safe for recreational athletes, but they should be aware of their individual risks. Conclusion: Individualized and appropriate acclimatization is an essential component of injury and illness prevention. PMID:26863894

    The purpose of the present study was to assess the exact conditions under which cerebral concussions occur in full-contact taekwondo competition. Injury data were collected by project staff and tournament medical personnel with simple check-off forms that describe the athlete and nature, site, circumstances and severity of the injury. The Mann-Whitney U test was used to determine the difference in injury rate between men and women. The men (7.04/1,000 athlete-exposures) sustained more cerebral concussions than the women (2.42/1,000 athlete-exposures) (p < 0.001). The dominant injury mechanism in both the males and females was receiving a blow (6.46/1,000 athlete-exposures and 2.42/1,000 athlete-exposures for the men and women, respectively).

    Systemic chemotherapy comprising anthracycline monotherapy is the standard regimen for metastatic soft tissue sarcomas, particularly leiomyosarcomas, which have limited sensitivity to ifosfamide. However, the optimal chemotherapy regimen for elderly patients, especially those considered unfit for anthracyclines, is undefined. Trabectedin is a potent marine-derived antineoplastic drug with documented activity in liposarcomas and leiomyosarcomas. It is registered in Europe for the treatment of adult patients with advanced soft tissue sarcoma, after failure of anthracyclines and ifosfamide, or who are unsuited to receive these agents. We report the long-term response to first-line trabectedin therapy in an elderly patient with metastatic leiomyosarcoma unfit for standard therapy. A 66-year-old woman underwent resection of a pelvic epithelioid leiomyosarcoma with positive margins in December 2002, followed by postoperative radiotherapy. In February 2012, she was diagnosed with multiple lung lesions and local relapse in the pelvis. As she was considered unsuitable for both anthracycline and ifosfamide because of cardiovascular comorbidities and because she was highly anxious at the prospect of developing alopecia, vomiting, and fatigue, we commenced treatment with trabectedin at 75% of the standard dose of 1.5 mg/m2 every 3 weeks. Treatment was well tolerated, and the patient continued treatment for 25 cycles, with disease stabilization according to the RECIST criteria and a partial response according to the Choi criteria. Disease progression was observed in November 2013 and the patient died 20 months after the diagnosis of metastases. Trabectedin may represent an alternative option for highly selected elderly patients with metastatic sarcoma and unfit for anthracyclines; careful monitoring of toxicities is strongly recommended.

We operationalised athletic social connectedness as a sense of social belonging and sense of connection with teammates. We hypothesised that athletic social connectedness would be positively associated with task goals, negatively associated with ego goals, and would at least partially mediate the relationship between achievement goals and well-being. We administered questionnaires to female (N = 106; mean age = 20.47, SD = 1.12) and male (N = 100; mean age = 20.95, SD = 1.21) NCAA Division III college athletes. We tested our hypothesised model using structural equation modelling, which included testing a measurement model that specified four latent variables and then comparing the estimates generated by our hypothesised model with our data. We also tested three alternative models and found our hypothesised model to fit best. As predicted, there were significant indirect effects of task and ego motivation on well-being through athletic connectedness, demonstrating formal evidence of mediation. The r(2) coefficient indicated that the model explained 30% of the variance in well-being, a moderate effect size (Cohen, 1988). Discussion focuses on the importance of considering interpersonal constructs as a way to improve our understanding of relationship between task and ego goal orientations to well-being in athletes.

    Computers have been used in a variety of applications for athletics since the late 1950's. These have ranged from computer-controlled electric scoreboards to computer-designed pole vaulting poles. Described in this paper are a computer-based athletic injury reporting system and a computer-assisted football scouting system. The injury reporting…
