Qualitative study using interpretive description methodology. The purpose of this study was to better understand how ethical issues are experienced by university sports team athletic therapists and physical therapists. In clinical practice, sports teams are associated with a range of ethical issues. Issues commonly reported in the literature include confidentiality, return-to-play decisions, conflicts of interest, advertising, doping, and use of local anesthetic. To date, there has been limited examination of how athletic therapists and physical therapists involved with sports teams experience these ethical issues, and limited exploration of how these ethical issues, when encountered, are shaped by therapists' professional roles and responsibilities. Semi-structured interviews were conducted with 11 athletic or physical therapists working with sports teams in 5 Canadian provinces. The data were analyzed inductively, using a recursive approach and constant comparative techniques. Four key themes were developed relating to the participants' experiences of ethical issues: establishing and maintaining professional boundaries, striving for respectful and effective collaboration, seeking answers to ethical concerns, and living with the repercussions of challenging decisions. While many ethical issues reported by participants resemble those faced by sports medicine physicians, they are experienced in distinctive ways, due to differences in professional roles and identities. Issues concerning professional boundaries were also more prominent for the study participants than the literature has reported them to be for sports medicine physicians. Effective communication and enhanced collaboration appear to be key elements in managing these ethical challenges.

A variety of recovery strategies are used by athletes, although there is currently no research that investigates perceptions and usage of recovery by different competition levels of team sport athletes. The recovery techniques used by team sport athletes of different competition levels was investigated by survey. Specifically this study investigated if, when, why and how the following recovery strategies were used: active land-based recovery (ALB), active water-based recovery (AWB), stretching (STR), cold water immersion (CWI) and contrast water therapy (CWT). Three hundred and thirty-one athletes were surveyed. Fifty-seven percent were found to utilise one or more recovery strategies. Stretching was rated the most effective recovery strategy (4.4/5) with ALB considered the least effective by its users (3.6/5). The water immersion strategies were considered effective/ineffective mainly due to psychological reasons; in contrast STR and ALB were considered to be effective/ineffective mainly due to physical reasons. This study demonstrates that athletes may not be aware of the specific effects that a recovery strategy has upon their physical recovery and thus athlete and coach recovery education is encouraged. This study also provides new information on the prevalence of different recovery strategies and contextual information that may be useful to inform best practice among coaches and athletes.

The purpose of this paper was to report normative data on regional sweat sweat-sodium concentrations of various professional male team-sport athletes, and to compare sweat-sodium concentrations among sports. Data to this effect would inform our understanding of athlete sodium requirements, thus allowing for the individualisation of sodium replacement strategies. Accordingly, data from 696 athletes (Soccer, n = 270; Rugby, n = 181; Baseball, n = 133; American Football, n = 60; Basketball, n = 52) were compiled for a retrospective analysis. Regional sweat-sodium concentrations were collected using the pilocarpine iontophoresis method, and compared to self-reported measures collected via questionnaire. Sweat-sodium concentrations were significantly higher ( p < 0.05) in American football (50.4 ± 15.3 mmol·L -1 ), baseball (54.0 ± 14.0 mmol·L -1 ), and basketball (48.3 ± 14.0 mmol·L -1 ) than either soccer (43.2 ± 12.0 mmol·L -1 ) or rugby (44.0 ± 12.1 mmol·L -1 ), but with no differences among the N.American or British sports. There were strong positive correlations between sweat-sodium concentrations and self-reported sodium losses in American football ( r s = 0.962, p < 0.001), basketball ( r s = 0.953, p < 0.001), rugby ( r s = 0.813, p < 0.001), and soccer ( r s = 0.748, p < 0.001). The normative data provided on sweat-sodium concentrations might assist sports science/medicine practitioners in generating bespoke hydration and electrolyte-replacement strategies to meet the sodium demands of professional team-sport athletes. Moreover, these novel data suggest that self-reported measures of sodium loss might serve as an effective surrogate in the absence of direct measures; i.e., those which are more expensive or non-readily available.

Sport-specific nutrition: practical strategies for team sports.

PubMed

Holway, Francis E; Spriet, Lawrence L

2011-01-01

Implementation of a nutrition programme for team sports involves application of scientific research together with the social skills necessary to work with a sports medicine and coaching staff. Both field and court team sports are characterized by intermittent activity requiring a heavy reliance on dietary carbohydrate sources to maintain and replenish glycogen. Energy and substrate demands are high during pre-season training and matches, and moderate during training in the competitive season. Dietary planning must include enough carbohydrate on a moderate energy budget, while also meeting protein needs. Strength and power team sports require muscle-building programmes that must be accompanied by adequate nutrition, and simple anthropometric measurements can help the nutrition practitioner monitor and assess body composition periodically. Use of a body mass scale and a urine specific gravity refractometer can help identify athletes prone to dehydration. Sports beverages and caffeine are the most common supplements, while opinion on the practical effectiveness of creatine is divided. Late-maturing adolescent athletes become concerned about gaining size and muscle, and assessment of maturity status can be carried out with anthropometric procedures. An overriding consideration is that an individual approach is needed to meet each athlete's nutritional needs.

Background: There are a variety of proposed motivations for sport specialization, such as improving sport skills to an elite level, making all-star or travel teams, or receiving a scholarship or professional contract. However, there has not been a quantitative examination of the attitudes and beliefs that may be contributing to the trend of sport specialization and year-round sport participation. Purpose: The primary aim was to describe the attitudes and beliefs of youth club sport athletes regarding sport specialization and sport participation. A secondary objective was to investigate whether an association exists between the level of sport specialization and the belief in receiving a college scholarship. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 974 youth athletes (578 female; mean age, 14.2 ± 1.6 years) completed an anonymous questionnaire that focused on attitudes and beliefs toward sport specialization and sport participation. Questions were developed utilizing the feedback of a panel of content area experts and the University of Wisconsin Survey Center. Data were summarized using frequencies, proportions (%), and means ± SDs. Results: Fewer than half of all athletes (45.8%) believed that specialization increased their chances of getting injured either “quite a bit” or “a great deal.” However, 91% of athletes believed that specialization increased their chances of getting better at their sport either “quite a bit” or “a great deal.” Similarly, the majority of athletes believed that specialization increased their chances of making their high school team (80.9%) or a college team (66.9%) either “quite a bit” or “a great deal.” Overall, 15.7% of athletes believed that they were either “very” or “extremely” likely to receive a college scholarship based on athletic performance. Highly specialized athletes were nearly twice as likely to have a high belief in receiving a college scholarship

This study aimed to assess the impact of 3 heights of simulated altitude exposure on repeat-sprint performance in team-sport athletes. Ten trained male team-sport athletes completed 3 sets of repeated sprints (9 × 4 s) on a nonmotorized treadmill at sea level and at simulated altitudes of 2000, 3000, and 4000 m. Participants completed 4 trials in a random order over 4 wk, with mean power output (MPO), peak power output (PPO), blood lactate concentration (Bla), and oxygen saturation (SaO2) recorded after each set. Each increase in simulated altitude corresponded with a significant decrease in SaO2. Total work across all sets was highest at sea level and correspondingly lower at each successive altitude (P < .05; sea level < 2000 m < 3000 m < 4000 m). In the first set, MPO was reduced only at 4000 m, but for subsequent sets, decreases in MPO were observed at all altitudes (P < .05; 2000 m < 3000 m < 4000 m). PPO was maintained in all sets except for set 3 at 4000 m (P < .05; vs sea level and 2000 m). BLa levels were highest at 4000 m and significantly greater (P < .05) than at sea level after all sets. These results suggest that "higher may not be better," as a simulated altitude of 4000 m may potentially blunt absolute training quality. Therefore, it is recommended that a moderate simulated altitude (2000-3000 m) be employed when implementing intermittent hypoxic repeat-sprint training for team-sport athletes.

2012-07-01

The purpose of this systematic review was to assess the efficacy of training interventions aimed to prevent and to reduce anterior cruciate ligament injury (ACLI) rates in team sport players. We searched MEDLINE from January 1991 to July 2011 using the terms knee, ACL, anterior cruciate ligament, injury, prevention, training, exercise, and intervention. Nine out of 708 articles met the inclusion criteria and were independently rated by two reviewers using the McMaster Occupational Therapy Evidence-Based Practice Research Group scale. Consensus scores ranged from 3 to 8 out of 10. Seven out of nine studies demonstrated that training interventions have a preventive effect on ACLI. Collectively, the studies indicate there is moderate evidence to support the use of multifaceted training interventions, which consisted of stretching, proprioception, strength, plyometric and agility drills with additional verbal and/or visual feedback on proper landing technique to decrease the rate of ACLIs in team sport female athletes, while the paucity of data preclude any conclusions for male athletes.

Abstract Plyometric training (PT) is a very popular form of physical conditioning of healthy individuals that has been extensively studied over the last decades. In this article, we critically review the available literature related to PT and its effects on physical fitness in team sport athletes. We also considered studies that combined PT with other popular training modalities (e.g. strength/sprint training). Generally, short-term PT (i.e. 2-3 sessions a week for 4-16 weeks) improves jump height, sprint and agility performances in team sport players. Literature shows that short PT (<8 weeks) has the potential to enhance a wide range of athletic performance (i.e. jumping, sprinting and agility) in children and young adult amateur players. Nevertheless, 6 to 7 weeks training appears to be too short to improve physical performance in elite male players. Available evidence suggests that short-term PT on non-rigid surfaces (i.e. aquatic, grass or sand-based PT) could elicit similar increases in jumping, sprinting and agility performances as traditional PT. Furthermore, the combination of various plyometric exercises and the bilateral and unilateral jumps could improve these performances more than the use of single plyometric drills or traditional PT. Thus, the present review shows a greater effect of PT alone on jump and sprint (30 m sprint performance only) performances than the combination of PT with sprint/strength training. Although many issues related to PT remain to be resolved, the results presented in this review allow recommending the use of well-designed and sport-specific PT as a safe and effective training modality for improving jumping and sprint performance as well as agility in team sport athletes.

In modern training technology, assessment of aerobic bioenergetic potential in athletes is commonly performed by standard laboratory procedures to determine basic or specific functional abilities for specific sport activity or discipline. The aim of study was to assess the aerobic bioenergetic potential of athletes participating in basketball, football and handball. The study included 87 athletes (29 basketball players, 29 football players, and 29 handball players) aged 21-24. Evaluation of the aerobic bioenergetic potential of athletes participating in basketball, football and handball was performed followed by both univariate (ANOVA) and multivariate (MANOVA) statistical methods to determine differences among the athletes in relative (VO2 mL/kg/min) and absolute oxygen consumption (VO2 L/min). Statistically significant differences between absolute and relative oxygen consumption were found in basketball players (Mb), football players (Mf), and handball players (Mh) (MANOVA, p = 0.00). ANOVA also revealed significant differences in relative oxygen consumption (VO2 mL/kg/min) (p = 0.00). The football players (55.32 mL/kg/min) had the highest relative oxygen consumption, followed by the handball players (51.84 mL/kg/min) and basketball players (47.00 mL/kg/min). The highest absolute oxygen consumption was recorded in the basketball players (4.47 L/min), followed by the handball players (4.40 L/min) and footballers (4.16 L/min). Statistically significant differences in the aerobic bioenergetic potential, expressed by the relative oxygen consumption were found among atletes participating in different team sports. It can be assumed that the player from the sports in which it is necessary to cross greater distance in total during the match have a greater need for aerobic capacity.

Medical expenses for collegiate athletics include providing a training room with its supplies, equipment, personnel costs, and insurance coverage. Additional expenses beyond the training room include imaging, diagnostic testing, specialty consultations, and surgeries. We hypothesized that there would be no difference in average expenses or number of claims between male and female athletes over a 5-year period. Prospective patient cohort. A sports medicine center serving athletes in Big 10 Conference intercollegiate sports. All medical claims and charges for 36 varsity teams were analyzed from 2005 to 2010. The teams were categorized into 3 groups: female-only teams, male-only teams, and coed teams. Analysis of sports with corresponding male and female teams was also performed. Claims and charges for medical care for 36 intercollegiate athletic teams over 5 years. Individual team claims and charges were stable over the study period. In 11 of the 14 sex-matched sports, the female teams had higher average annual charges. After normalizing for roster size in the sex-matched sports, females had 0.97 more average annual claims (P < 0.01) and $1459 higher annual charges (P = 0.001) than their male counterparts. The charges per claim were similar between the sexes. The 5 teams with the highest average annual charges were football, wrestling, softball, women's crew, and men's lacrosse. When normalized for roster size, the 5 sports with the highest average annual charges per athlete were softball, women's diving, men's basketball, wrestling, and men's gymnastics. Charges per claim were similar between the sex-matched sports, but the female sports had a higher number of annual claims per athlete and thus higher total charges per athlete/year. Football had the highest average annual total charges as a team, but when normalized for roster size football charges per athlete/year were similar to those of other sports.

This research aimed to introduce social network analysis as a novel technique in sports teams to identify the attributes of high-quality athlete leadership, both at the individual and at the team level. Study 1 included 25 sports teams (N = 308 athletes) and focused on athletes' general leadership quality. Study 2 comprised 21 sports teams (N = 267 athletes) and focused on athletes' specific leadership quality as a task, motivational, social, and external leader. The extent to which athletes felt connected with their leader proved to be most predictive for athletes' perceptions of that leader's quality on each leadership role. Also at the team level, teams with higher athlete leadership quality were more strongly connected. We conclude that social network analysis constitutes a valuable tool to provide more insight in the attributes of high-quality leadership both at the individual and at the team level.

Use of integrated technology in team sports: a review of opportunities, challenges, and future directions for athletes.

Integrated technology (IT), which includes accelerometers, global positioning systems (GPSs), and heart rate monitors, has been used frequently in public health. More recently, IT data have been used in sports settings to assess training and performance demands. However, the impact of IT in sports settings is yet to be evaluated, particularly in field-based team sports. This narrative-qualitative review provides an overview of the emerging impact of IT in sports settings. Twenty electronic databases (e.g., Medline, SPORTdiscus, and ScienceDirect), print publications (e.g., Signal Processing Magazine and Catapult Innovations news releases), and internet resources were searched using different combinations of keywords as follows: accelerometers, heart rate monitors, GPS, sport training, and field-based sports for relevant articles published from 1990 to the present. A total of 114 publications were identified, and 39 that examined a field-based team sport using a form of IT were analyzed. The articles chosen for analysis examined a field-based team sport using a form of IT. The uses of IT can be divided into 4 categories: (a) quantifying movement patterns (n = 22), (b) assessing the differences between demands of training and competition (n = 12), (c) measuring physiological and metabolic responses (n = 16), and (d) determining a valid definition for velocity and a sprint effort (n = 8). Most studies used elite adult male athletes as participants and analyzed the sports of Australian Rules football, field hockey, cricket, and soccer, with sample sizes between 5 and 20 participants. The limitations of IT in a sports setting include scalability issues, cost, and the inability to receive signals within indoor environments. Integrated technology can contribute to significant improvements in the preparation, training, and recovery aspects of field-based team sports. Future research should focus on using IT with female athlete populations and developing resources to use IT

Dietary supplements and team-sport performance.

PubMed

Bishop, David

2010-12-01

A well designed diet is the foundation upon which optimal training and performance can be developed. However, as long as competitive sports have existed, athletes have attempted to improve their performance by ingesting a variety of substances. This practice has given rise to a multi-billion-dollar industry that aggressively markets its products as performance enhancing, often without objective, scientific evidence to support such claims. While a number of excellent reviews have evaluated the performance-enhancing effects of most dietary supplements, less attention has been paid to the performance-enhancing claims of dietary supplements in the context of team-sport performance. Dietary supplements that enhance some types of athletic performance may not necessarily enhance team-sport performance (and vice versa). Thus, the first aim of this review is to critically evaluate the ergogenic value of the most common dietary supplements used by team-sport athletes. The term dietary supplements will be used in this review and is defined as any product taken by the mouth, in addition to common foods, that has been proposed to have a performance-enhancing effect; this review will only discuss substances that are not currently banned by the World Anti-Doping Agency. Evidence is emerging to support the performance-enhancing claims of some, but not all, dietary supplements that have been proposed to improve team-sport-related performance. For example, there is good evidence that caffeine can improve single-sprint performance, while caffeine, creatine and sodium bicarbonate ingestion have all been demonstrated to improve multiple-sprint performance. The evidence is not so strong for the performance-enhancing benefits of β-alanine or colostrum. Current evidence does not support the ingestion of ribose, branched-chain amino acids or β-hydroxy-β-methylbutyrate, especially in well trained athletes. More research on the performance-enhancing effects of the dietary supplements

In recent years, athletic participation has more than doubled in all major demographic groups, while simultaneously, children and adults with established heart disease desire participation in sports and exercise. Despite conferring favorable long-term effects on well-being and survival, exercise can be associated with risk of adverse events in the short term. Complex individual cardiovascular (CV) demands and adaptations imposed by exercise present distinct challenges to the cardiologist asked to evaluate athletes. Here, we describe the evolution of sports and exercise cardiology as a unique discipline within the continuum of CV specialties, provide the rationale for tailoring of CV care to athletes and exercising individuals, define the role of the CV specialist within the athlete care team, and lay the foundation for the development of Sports and Exercise Cardiology in the United States. In 2011, the American College of Cardiology launched the Section of Sports and Exercise Cardiology. Membership has grown from 150 to over 4,000 members in just 2 short years, indicating marked interest from the CV community to advance the integration of sports and exercise cardiology into mainstream CV care. Although the current athlete CV care model has distinct limitations, here, we have outlined a new paradigm of care for the American athlete and exercising individual. By practicing and promoting this new paradigm, we believe we will enhance the CV care of athletes of all ages, and serve the greater athletic community and our nation as a whole, by allowing safest participation in sports and physical activity for all individuals who seek this lifestyle.

Baker, Lindsay B; Heaton, Lisa E; Nuccio, Ryan P; Stein, Kimberly W

2014-04-01

Sports nutrition experts recommend that team-sport athletes participating in intermittent high-intensity exercise for ≥1 hr consume 1-4 g carbohydrate/kg 1-4 hr before, 30-60 g carbohydrate/hr during, and 1-1.2 g carbohydrate/kg/hr and 20-25 g protein as soon as possible after exercise. The study objective was to compare observed vs. recommended macronutrient intake of competitive athletes under free-living conditions. The dietary intake of 29 skill/team-sport athletes (14-19 y; 22 male, 7 female) was observed at a sports training facility by trained registered dietitians for one 24-hr period. Dietitians accompanied subjects to the cafeteria and field/court to record their food and fluid intake during meals and practices/competitions. Other dietary intake within the 24-hr period (e.g., snacks during class) was accounted for by having the subject take a picture of the food/fluid and completing a log. For male and female athletes, respectively, the mean ± SD (and percent of athletes meeting recommended) macronutrient intake around exercise was 1.4 ± 0.6 (73%) and 1.4 ± 1.0 (57%) g carbohydrate/kg in the 4 hr before exercise, 21.1 ± 17.2 (18%) and 18.6 ± 13.2 (29%) g carbohydrate/hrr during exercise, 1.4±1.1 (68%) and 0.9± 1.0 (43%) g carbohydrate/kg and 45.2 ± 36.9 (73%) and 18.0 ± 21.2 (43%) g protein in the 1 hr after exercise. The male athletes' carbohydrate and protein intake more closely approximated recommendations overall than that of the female athletes. The most common shortfall was carbohydrate intake during exercise, as only 18% of male and 29% of female athletes consumed 3060 g carbohydrate/hr during practice/competition.

The purpose of this study was to identify the quantity and type of sporting activities undertaken by expert team sport athletes in the earlier stages of the long- term athlete development. Experts in roller-hockey (n = 19), volleyball (n = 14), soccer (n = 42) and basketball (n = 37) provided detailed information about the sporting activities they undertook throughout their careers. Results showed considerable variation between and within sports; however, generally, athletes began participating in sports between 6 and 10 years of age. The pattern of participation in specific and non-specific (team, individual and combat) sports for each stage of involvement demonstrated an increase in the number of activities participated in until early adolescence. Our results suggest that involvement in multiple sports during early stages of development is an alternative to early specialization and add further evidence of the complexity of skill acquisition in sport. Key points Although most athletes began sport participation between 6 and 10 years of age, there was significant variation across groups suggesting considerable flexibility in the pathways to expertise. The path to expertise in volleyball was clearly distinct from the paths of basketball, soccer and roller-hockey. There is a considerable involvement in sports other than the athlete’s primary sport, suggesting early specialization is not required for these sports. The pattern of participation in specific and non-specific sports for each stage of involvement demonstrated an increase in the number of activities participated in until early adolescence.

Organizational socialization in team sport environments.

Benson, A J; Evans, M B; Eys, M A

2016-04-01

Socialization tactics are often used to manage initial group member interactions in a way that facilitates transition experiences. Although this process is heavily researched in organizational contexts, we sought to extend this line of inquiry to sport by examining the nature of socialization tactics used to integrate new members into existing teams. Interviews were conducted with 12 coaches and 12 athletes from several Canadian Interuniversity Sport teams to explore the nature of socialization and the circumstances underscoring why certain approaches are taken over others. A key process involved establishing congruency of role expectations between incoming athletes and group leaders, and socialization processes balanced expectations of conformity with encouragement of individual personalities within the group. A conceptual basis to examine socialization into team sport environments is discussed in relation to the extant organizational theories, and the practical implications of delineating sport socialization tactics are forwarded. © 2015 John Wiley & Sons A/S.

To determine the association between the α-actinin-3 (ACTN3) R577X polymorphism and elite team-sport athletic status in three cohorts of European team-sport athletes. We compared the genotype and allele frequencies of the ACTN3 R577X (rs1815739) polymorphisms between team-sport athletes (n=205), endurance athletes (n=305), sprint/power athletes (n=378), and non-athletic controls (n=568) from Poland, Russia and Spain; all participants were unrelated European men. Genomic DNA was extracted from either buccal epithelium or peripheral blood using a standard protocol. Genotyping was performed using several methods, and the results were replicated following recent recommendations for genotype-phenotype association studies. Genotype distributions of all control and athletic groups met Hardy-Weinberg equilibrium (all p>0.05). Team-sport athletes were less likely to have the 577RR genotype compared to the 577XX genotype than sprint/power athletes [odds ratio: 0.58, 95% confidence interval: 0.34-0.39, p=0.045]. However, the ACTN3 R577X polymorphism was not associated with team-sports athletic status, compared to endurance athletes and non-athletic controls. Furthermore, no association was observed for any of the genotypes with respect to the level of competition (elite vs. national level). The ACTN3 R577X polymorphism was not associated with team-sport athletic status, compared to endurance athletes and non-athletic controls, and the observation that the 577RR genotype is overrepresented in power/sprint athletes compared with team-sport athletes needs to be confirmed in future studies.

With the advent of the National Collegiate Athletic Association's (NCAA's) mandating the presence and practice of concussion-management plans in collegiate athletic programs, institutions will consider potential approaches for concussion management, including both baseline and normative comparison approaches. To examine sport and team differences in baseline performance on a computer-based neurocognitive measure and 2 standard sideline measures of cognition and balance and to determine the potential effect of premorbid factors sex and height on baseline performance. Cross-sectional study. University laboratory. A total of 437 NCAA Division II student-athletes (males = 273, females = 164; age = 19.61 ± 1.64 years, height = 69.89 ± 4.04 inches [177.52 ± 10.26 cm]) were recruited during mandatory preseason testing conducted in a concussion-management program. The computerized Concussion Resolution Index (CRI), the Standardized Assessment of Concussion (Form A; SAC), and the Balance Error Scoring System (BESS). Players on the men's basketball team tended to perform worse on the baseline measures, whereas soccer players tended to perform better. We found a difference in total BESS scores between these sports (P = .002). We saw a difference between sports on the hard-surface portion of the BESS (F6,347 = 3.33, P = .003, ηp(2) = 0.05). No sport, team, or sex differences were found with SAC scores (P > .05). We noted differences between sports and teams in the CRI indices, with basketball, particularly the men's team, performing worse than soccer (P < .001) and softball/baseball (P = .03). When sex and height were considered as possible sources of variation in BESS and CRI team or sport differences, height was a covariate for the team (F1,385 = 5.109, P = .02, ηp(2) = 0.013) and sport (F1,326 = 11.212, P = .001, ηp(2) = 0.033) analyses, but the interaction of sex and sport on CRI indices was not significant in any test (P > .05).

Talent development in adolescent team sports: a review.

PubMed

Burgess, Darren J; Naughton, Geraldine A

2010-03-01

Traditional talent development pathways for adolescents in team sports follow talent identification procedures based on subjective games ratings and isolated athletic assessment. Most talent development models are exclusive rather than inclusive in nature. Subsequently, talent identification may result in discontentment, premature stratification, or dropout from team sports. Understanding the multidimensional differences among the requirements of adolescent and elite adult athletes could provide more realistic goals for potential talented players. Coach education should include adolescent development, and rewards for team success at the adolescent level should reflect the needs of long-term player development. Effective talent development needs to incorporate physical and psychological maturity, the relative age effect, objective measures of game sense, and athletic prowess. The influences of media and culture on the individual, and the competing time demands between various competitions for player training time should be monitored and mediated where appropriate. Despite the complexity, talent development is a worthy investment in professional team sport.

People high in rumination are good at tasks that require persistence whereas people low in rumination is good at tasks that require flexibility. Here we examine real world implications of these differences in dynamic, team sport. In two studies, we found that professional male football (soccer) players from Germany and female field hockey players on the US national team were lower in rumination than were non-athletes. Further, low levels of rumination were associated with a longer career at a higher level in football players. Results indicate that athletes in dynamic, team sport might benefit from the flexibility associated with being low in rumination. PMID:26779110

The consumption of milk following eccentric exercise attenuates the effects of muscle damage in team-sport athletes. However, participation in team sport involves both concentric-eccentric loading and metabolic stress. Therefore, the aim of this study was to investigate the effects of postexercise milk consumption on recovery from a cycling protocol designed to simulate the metabolic demands of team sport. Ten female team-sport athletes participated in a randomised crossover investigation. Upon completion of the protocol participants consumed 500 mL of milk (MILK) or 500 mL of an energy-matched carbohydrate (CHO) drink. Muscle function (peak torque, rate of force development, countermovement jump, 20-m sprint), muscle soreness and tiredness, serum creatine kinase, high-sensitivity C-reactive protein, and measures of oxidative stress (protein carbonyls and reduced glutathione/oxidized glutathione (GSH/GSSG) ratio) were determined at pre-exercise and 24 h, 48 h, and 72 h postexercise. MILK had a possible beneficial effect in attenuating losses in peak torque (180°/s) from baseline to 24 h (3.2% ± 7.8% vs. -6.2% ± 7.5%, MILK vs. CHO) and a possible beneficial effect in minimising soreness (baseline-48 h; baseline-72 h) and tiredness (baseline-24 h; baseline-72 h). There was no change in oxidative stress following the exercise protocol, though a likely benefit of milk was observed for GSH/GSSG ratio at baseline-24 h (0.369 ×/÷ 1.89, 1.103 ×/÷ 3.96, MILK vs. CHO). MILK had an unclear effect on all other variables. Consumption of 500 mL of milk after repeat sprint cycling had little to no benefit in minimising losses in peak torque or minimising increases in soreness and tiredness and had no effect on serum markers of muscle damage and inflammation.

Web-based 24-h dietary recalls and questionnaires were obtained from 553 Dutch well-trained athletes. The total energy and macronutrient intake was compared between discipline-categories (endurance, team, and strength) within gender, and dietary inadequacy, i.e., too low or high intakes, according to selected recommendations and guidelines, was evaluated by applying a probability approach. On average, 2.83 days per person were reported with a mean energy intake of 2566-2985 kcal and 1997-2457 kcal per day, for men and women, respectively. Between disciplines, small differences in the mean intake of energy and macronutrients were seen for both men and women. Overall, 80% of the athletes met the suggested lower-limit sport nutrition recommendation of 1.2 g·kg -1 of protein per day. The carbohydrate intake of 50%-80% of athletes was between 3 and 5 g·kg -1 bodyweight, irrespective of the category of their discipline. This can be considered as low to moderate, in view of their daily total exercise load (athletes reported on average ~100 minutes per day). In conclusion, only small differences in the mean energy and macronutrient intake between elite endurance, strength, and team sport athletes, were found. The majority of the athletes were able to meet the generally accepted protein recommendation for athletes, of 1.2 g·kg -1 . However, for most athletes, the carbohydrate intake was lower than generally recommended in the existing consensus guidelines on sport nutrition. This suggests that athletes could either optimize their carbohydrate intake, or that average carbohydrate requirements merit a re-evaluation.

Preventing sports injuries: opportunities for intervention in youth athletics.

Participation in youth sports has steadily grown over the past 30 years and continues to rise. During the 1998-1999 school year over 360,000 collegiate athletes and almost 6.5 million high school athletes participated in sports. This expansion has been accompanied by an increased awareness of the injury problem associated with participation in youth sports. Estimates are that one-third of high school athletes will sustain an injury during a sports season serious enough to result in time lost from participation. While there may always be some risk associated with sports participation, health professionals can actively encourage injury prevention. In this paper, we describe the benefits of sport participation, the injury problem associated with sports, injury prevention frameworks, and conclude by discussing the changing role of the team physician in youth sports.

This study compared sports injury incidence in young high-level athletes from various team and individual sports and investigated if sport participation patterns are linked to injuries. Prospective cohort follow-up. Pupils from a public sports school (12-19 years) were recruited over two separate school years (2008-2009: 42 weeks, n=199 athletes; 2009-2010: 40 weeks, n=89 athletes). Training and competition volume and intensity were recorded via a personal sports diary. Sports injuries (time-loss definition) were registered by medical staff members using a standardized questionnaire. Injury incidence was significantly higher in team compared with individual sports (6.16 versus 2.88 injuries/1000h, respectively), as a result of a higher incidence of both traumatic (RR=2.17; CI95%=1.75-2.70; p<0.001), and overuse injuries (RR=2.06; CI95%=1.46-2.91; p<0.001). A Cox proportional hazards regression revealed that team sports participation had a hazard ratio of 2.00 (CI95%=1.49-2.68; p<0.001) compared to individual sports, with additionally previous injury being a risk and age a protective factor. The number of competitions per 100 days was significantly higher in team sports, whereas the number of intense training sessions per 100 days was significantly lower. In team sports, the number of competitions per 100 days was positively associated with injuries (HR=1.072; CI95% [1.033; 1.113]; p<0.001), while in individual sports the number of competitions per 100 days had a protective effect (HR=0.940; CI95% [0.893; 0.989]; p=0.017). Team sports participation entailed a higher injury risk, whatever the injury category. Further research should elucidate the role of characteristics related to sport participation in injury causation. Copyright © 2012 Sports Medicine Australia. Published by Elsevier Ltd.

Peaking for major competition is considered critical for maximizing team-sport performance. However, there is little scientific information available to guide coaches in prescribing efficient tapering strategies for team-sport players. To monitor the changes in physical performance in elite team-sport players during a 3-wk taper after a preseason training camp. Ten male international rugby sevens players were tested before (Pre) and after (Post) a 4-wk preseason training camp focusing on high-intensity training and strength training with moderate loads and once each week during a subsequent 3-wk taper. During each testing session, midthigh-pull maximal strength, sprint-acceleration mechanical outputs, and performance, as well as repeated-sprint ability (RSA), were assessed. At Post, no single peak performance was observed for maximal lower-limb force output and sprint performance, while RSA peaked for only 1 athlete. During the taper, 30-m-sprint time decreased almost certainly (-3.1% ± 0.9%, large), while maximal lower-limb strength and RSA, respectively, improved very likely (+7.7% ± 5.3%, small) and almost certainly (+9.0% ± 2.6%, moderate). Of the peak performances, 70%, 80%, and 80% occurred within the first 2 wk of taper for RSA, maximal force output, and sprint performance, respectively. These results show the sensitivity of physical qualities to tapering in rugby sevens players and suggest that an ~1- to 2-wk tapering time frame appears optimal to maximize the overall physical-performance response.

Four-year changes in college athletes' ethical value choices in sports situations.

Positive values for fairness in competition are supposed to undergird the behavior of athletes engaged in sport. Whether athletes' values actually develop over 4 years in a college that emphasizes character development is the focus of this study. Athletes' (N = 631) use of deontological ethics (Hahm, Beller & Stoll, 1989) in 21 sports value dilemmas were evaluated. At entrance, as well as near graduation, intercollegiate athletes' value scores were lower than intramural athletes' scores. Both groups' scores declined while they were in college. Individual-sport athletes had higher scores than team-sport athletes but manifested a greater decline over 4 years. The findings are consistent with other studies that show decreases in "sportsmanship orientation" and an increase in "professional" attitudes associated with participation in sport.

Factors relevant to the working alliance between athletes and sport psychology consultants were investigated in a sample of elite Malaysian athletes (n = 217). The athletes represented a variety of team and individual sports, and they provided information about the perceived importance of seven consultant characteristics/behaviors as well as seven program delivery options. At a full-sample level, general preferences were expressed for consultants to lead a physically active lifestyle, regularly attend training sessions and competitions, and have prior experience as an athlete or coach. General preferences were also expressed for program content to be determined by the coach or consultant, and for regular, small doses of mental skills training to be delivered in a face-to-face context throughout the year. At a sub-group level, team sport athletes had stronger preferences than individual sport athletes for program delivery on a group/team basis, while individual sport athletes had stronger preferences than team sport athletes for having a role in determining program content. Findings are discussed in relation to dominant value themes within Malaysian society and the reinforcement of these themes within specific sport subcultures. Key points Consultant characteristics and program delivery methods have an impact on the effectiveness of sport psychology services. Preferred consultant characteristics and preferred methods of delivery may be affected by cultural and subcultural values. Elite Malaysian athletes prefer consultants to lead a physically active lifestyle; to regularly attend training/competition; and to have prior experience as an athlete or coach.

Careful modulation of training characteristics in high-level sports optimizes performance and avoids inappropriate workloads and associated sports injury risk. The aims of this study were to compare sport participation characteristics in different youth sport categories and to investigate their relationship with injury. Prospective cohort follow-up. Young (12-19 years) high-level athletes (n=154) from a regional sport school were followed during 41 weeks regarding sport participation characteristics and traumatic and overuse sports injuries (time-loss definition). All data were self-recorded by the athletes in an electronic system "TIPPS" (Training and Injury Prevention Platform for Sports) and subject to a systematic data quality control. Volume and intensity (self-rated perceived exertion) of each sport session were used to compute weekly load, monotony and strain. Sport categories were defined as team, racket, and individual sports. All sport participation characteristics were dependent on sport category (p<0.05). Weekly intensity, load and strain were dependent on age (p<0.05). Racket and individual sports were associated with lower injury risk (HR=0.37 and 0.34, p=0.001 and p<0.001, respectively) compared to team sports. Average sport participation characteristics were not related to injury according to the survival analysis. However, intensity during the week prior to injury was significantly higher (p<0.01) compared to that of the 4 preceding weeks. This study investigated for the first time the relationship between sport participation pattern and injury risk in young athletes. The monitoring method was sensitive to variations according to pertinent variables and might help identify athletes with increased sports injury risk. Copyright © 2013 Sports Medicine Australia.

Principles of Liability for Athletic Trainers: Managing Sport-Related Concussion

PubMed Central

2001-01-01

Objective: To provide an overview of the general legal principles of negligence for sports medicine professionals and apply these principles to situations involving athletes with head injury. Data Sources: Case law dating back to 1976 and recent studies of sport-related concussion. Summary: One of the most difficult problems facing athletic trainers and team physicians is the recognition and treatment of sport-related concussion. Providing medical clearance for sports participation and treatment of athletic injuries involves legal as well as medical issues. The threat of lawsuits exists for the sports medicine professional, whether the athlete is allowed to play or not. In general, established medical malpractice principles govern claims by athletes for injury or death caused by improper treatment by health care providers. The elements of negligence are examined, as well as the primary defenses an athletic trainer would use in court and risk management techniques to avoid litigation. Conclusions/Recommendations: Athletic trainers may protect themselves from liability by including standardized cognitive or postural stability testing in preparticipation examinations, using objective tests rather than subjective judgement to evaluate athletes who have sport-related concussion, working closely with physicians, and keeping excellent records.

High school athletes are increasingly encouraged to participate in 1 sport year-round to increase their sport skills. However, no study has examined the association of competition volume, club sport participation, and sport specialization with sex and lower extremity injury (LEI) in a large sample of high school athletes. Increased competition volume, participating on a club team outside of school sports, and high levels of specialization will all be associated with a history of LEI. Girls will be more likely to engage in higher competition volume, participate on a club team, and be classified as highly specialized. Cross-sectional study. Level 3. High school athletes completed a questionnaire prior to the start of their competitive season regarding their sport participation and previous injury history. Multivariable logistic regression analyses were used to investigate associations of competition volume, club sport participation, and sport specialization with history of LEI, adjusting for sex. A cohort of 1544 high school athletes (780 girls; grades 9-12) from 29 high schools completed the questionnaire. Girls were more likely to participate at high competition volume (23.2% vs 11.0%, χ 2 = 84.7, P < 0.001), participate on a club team (61.2% vs 37.2%, χ 2 = 88.3, P < 0.001), and be highly specialized (16.4% vs 10.4%, χ 2 = 19.7, P < 0.001). Athletes with high competition volume, who participated in a club sport, or who were highly specialized had greater odds of reporting a previous LEI than those with low competition volume (odds ratio [OR], 2.08; 95% CI, 1.55-2.80; P < 0.001), no club sport participation (OR, 1.50; 95% CI, 1.20-1.88; P < 0.001), or low specialization (OR, 2.58; 95% CI, 1.88-3.54; P < 0.001), even after adjusting for sex. Participating in high sport volume, on a club team, or being highly specialized was associated with history of LEI.

There has been little documentation of what constitutes the clinical work of intercollegiate team physicians. Team physicians could be recruited based on the needs of athletes. A multidisciplinary team of physicians is necessary to treat college athletes. Most physician evaluations are for musculoskeletal injuries treated nonoperatively. Descriptive epidemiology study. For a 2-year period, a database was created that recorded information on team physician encounters with intercollegiate athletes at a major university. Data on imaging studies, hospitalizations, and surgeries were also recorded. The diagnoses for physician encounters with all undergraduates through the university's health service were also recorded. More initial athlete evaluations were for musculoskeletal diagnoses (73%) than for general medical diagnoses (27%) (P < .05). Four percent of musculoskeletal injuries required surgery. Most general medical evaluations were single visits for upper respiratory infections and dermatologic disorders, or multiple visits for concussions. Football accounted for 22% of all physician encounters, more than any other sport (P < .05). Per capita, men and women sought care at an equal rate. In contrast, 10% of physician encounters with the general pool of undergraduates were for musculoskeletal diagnoses. Student athletes did not require a greater number of physician encounters than did the general undergraduate pool of students on a per capita basis. Intercollegiate team physicians primarily treat musculoskeletal injuries that do not require surgery. General medical care is often single evaluations of common conditions and repeat evaluations for concussions.

Kons, RL, Ache-Dias, J, Detanico, D, Barth, J, and Dal Pupo, J. Is vertical jump height an indicator of athletes' power output in different sports modalities? J Strength Cond Res 32(3): 708-715, 2018-This study aimed to identify whether the ratio standard is adequate for the scaling of peak power output (PPO) for body mass (BM) in athletes of different sports and to verify classification agreement for athletes involved in different sports using PPO scaled for BM and jump height (JH). One hundred and twenty-four male athletes divided into 3 different groups-combat sports, team sports, and runners-participated in this study. Participants performed the countermovement jump on a force plate. Peak power output and JH were calculated from the vertical ground reaction force. We found different allometric exponents for each modality, allowing the use of the ratio standard for team sports. For combat sports and runners, the ratio standard was not considered adequate, and therefore, a specific allometric exponent for these 2 groups was found. Significant correlations between adjusted PPO for BM (PPOADJ) and JH were found for all modalities, but it was higher for runners (r = 0.81) than team and combat sports (r = 0.63 and 0.65, respectively). Moderate agreement generated by the PPOADJ and JH was verified in team sports (k = 0.47) and running (k = 0.55) and fair agreement in combat sports (k = 0.29). We conclude that the ratio standard seems to be suitable only for team sports; for runners and combat sports, an allometric model seems adequate. The use of JH as an indicator of power output may be considered reasonable only for runners.

Differences in self-regulatory skills among talented athletes: the significance of competitive level and type of sport.

Research has shown that talented athletes outscore their mainstream peers on the basis of self-regulation. Although valuable, this does not tell us more about the distinction between good athletes and the best, which is a prerequisite in talent development. Therefore, we examined the self-regulatory skills of 222 male and female talented athletes aged 12-16 years as a function of competitive sport level (junior international or junior national athletes) and type of sport (individual or team sports). Multivariate analyses of covariance in combination with a discriminant function analysis revealed that "reflection" distinguishes between athletes at the highest levels of excellence. Furthermore, athletes playing individual sports had higher scores on "planning" and "effort" than team sport athletes, highlighting the importance of differences between types of sport. In conclusion, we emphasize the importance of reflection as a self-regulatory skill. Reflection facilitates the development of sport-specific characteristics, which may vary by type of sport. This means that an advanced sense of reflection may help talented athletes to acquire desirable characteristics during their "talent" years to ultimately reach adult elite levels of competition.

Athletes' perceptions of role ambiguity and coaching competency in sport teams: a multilevel analysis.

2012-06-01

The purpose of this study was to examine the relationship between athletes' perceptions of role ambiguity and two theoretically derived dimensions of coaching competency (i.e., game strategy and technique competencies). A total of 243 players from 26 teams representing various interdependent sports completed French versions of the Role Ambiguity Scale and the Coaching Competency Scale. Multilevel analyses supported the existence of relationships between the four dimensions of role ambiguity and the two dimensions of coaching competency at both individual and team levels. When the levels were considered jointly, athletes perceiving greater ambiguity in their role in both offensive and defensive contexts were more critical of their coach's capacities to lead their team during competitions and to diagnose or formulate instructions during training sessions. The results also indicated that the dimension of scope of responsibilities was the main contributor to the relationship with coaching competency at an individual level, whereas role evaluation was the main contributor to this relationship at a group level. Findings are discussed in relation to the role episode model, the role ambiguity dimensions involved in the relationships according to the level of analysis considered, and the salience of ambiguity perceptions in the offensive context.

However, no study has examined the association of competition volume, club sport participation, and sport specialization with sex and lower extremity injury (LEI) in a large sample of high school athletes. Hypothesis: Increased competition volume, participating on a club team outside of school sports, and high levels of specialization will all be associated with a history of LEI. Girls will be more likely to engage in higher competition volume, participate on a club team, and be classified as highly specialized. Study Design: Cross-sectional study. Level of Evidence: Level 3. Methods: High school athletes completed a questionnaire prior to the start of their competitive season regarding their sport participation and previous injury history. Multivariable logistic regression analyses were used to investigate associations of competition volume, club sport participation, and sport specialization with history of LEI, adjusting for sex. Results: A cohort of 1544 high school athletes (780 girls; grades 9-12) from 29 high schools completed the questionnaire. Girls were more likely to participate at high competition volume (23.2% vs 11.0%, χ2 = 84.7, P < 0.001), participate on a club team (61.2% vs 37.2%, χ2 = 88.3, P < 0.001), and be highly specialized (16.4% vs 10.4%, χ2 = 19.7, P < 0.001). Athletes with high competition volume, who participated in a club sport, or who were highly specialized had greater odds of reporting a previous LEI than those with low competition volume (odds ratio [OR], 2.08; 95% CI, 1.55-2.80; P < 0.001), no club sport participation (OR, 1.50; 95% CI, 1.20-1.88; P < 0.001), or low specialization (OR, 2.58; 95% CI, 1.88-3.54; P < 0.001), even after adjusting for sex. Conclusion: Participating in high sport volume, on a club team, or being highly specialized was associated with history of LEI. Girls were more likely to

Team sport athletes face a variety of nutritional challenges related to recovery during the competitive season. The purpose of this article is to review nutrition strategies related to muscle regeneration, glycogen restoration, fatigue, physical and immune health, and preparation for subsequent training bouts and competitions. Given the limited opportunities to recover between training bouts and games throughout the competitive season, athletes must be deliberate in their recovery strategy. Foundational components of recovery related to protein, carbohydrates, and fluid have been extensively reviewed and accepted. Micronutrients and supplements that may be efficacious for promoting recovery include vitamin D, omega-3 polyunsaturated fatty acids, creatine, collagen/vitamin C, and antioxidants. Curcumin and bromelain may also provide a recovery benefit during the competitive season but future research is warranted prior to incorporating supplemental dosages into the athlete's diet. Air travel poses nutritional challenges related to nutrient timing and quality. Incorporating strategies to consume efficacious micronutrients and ingredients is necessary to support athlete recovery in season.

Nutrition in team sports.

Team sports are based on intermittent high-intensity activity patterns, but the exact characteristics vary between and within codes, and from one game to the next. Despite the challenge of predicting exact game demands, performance in team sports is often dependent on nutritional factors. Chronic issues include achieving ideal levels of muscle mass and body fat, and supporting the nutrient needs of the training program. Acute issues, both for training and in games, include strategies that allow the player to be well fuelled and hydrated over the duration of exercise. Each player should develop a plan of consuming fluid and carbohydrate according to the needs of their activity patterns, within the breaks that are provided in their sport. In seasonal fixtures, competition varies from a weekly game in some codes to 2-3 games over a weekend road trip in others, and a tournament fixture usually involves 1-3 days between matches. Recovery between events is a major priority, involving rehydration, refuelling and repair/adaptation activities. Some sports supplements may be of value to the team athlete. Sports drinks, gels and liquid meals may be valuable in allowing nutritional goals to be met, while caffeine, creatine and buffering agents may directly enhance performance. Copyright © 2011 S.

Collegiate student-athletes. Sport-related concussion data from the National Collegiate Athletic Association Injury Surveillance Program during the 2011-2012 through 2014-2015 academic years were analyzed. We calculated concussion rates per 1000 athlete-exposures (AEs), concussion risk, average number of concussions per team, and percentage of teams with at least 1 concussion. During the 2011-2012 through 2014-2015 academic years, 1485 concussions were sustained by 1410 student-athletes across 13 sports. Concussion rates ranged from 0.09/1000 AEs in men's baseball to 0.89/1000 AEs in men's wrestling. Concussion risk ranged from 0.74% in men's baseball to 7.92% in men's wrestling. The average ± SD number of concussions per team ranged from 0.25 ± 0.43 in men's baseball to 5.63 ± 5.36 in men's football. The percentage of teams with a concussion ranged from 24.5% in men's baseball to 80.6% in men's football.   Although men's wrestling had a higher concussion rate and risk, men's football had the largest average number of concussions per team and the largest percentage of teams with at least 1 concussion.

Sport injury rehabilitation has moved from predominately physical treatment to a more holistic care. However, limited research has explored the views and experiences of those involved in such an approach. The purpose of this study was to preliminarily investigate sport psychology consultants' (SPCs') views and experiences of an interprofessional team approach to sport injury rehabilitation. A cross-sectional online survey previously used with athletic trainers was distributed via a US-based sport/exercise psychology list-serve (N = 1245). A total of 62 (27 men, 35 women, M age 38.2 years, age range: 22-73 years) participants with 10.6 (SD = 9.8) years of experience as an SPC were included in the final analyses. On average, SPCs felt that it was very important (M = 6.6; SD = 0.6) for athletes to have access to an interprofessional care team. Of the sample, 64.5% (n = 40) typically worked as part of an interprofessional care team 44.7% of the time. The SPCs (n = 28; 45.2%) also indicated that the primary treatment providers (e.g., athletic trainer, physical therapist) were typically serving as the primary point person for such teams. Since gaining entry to sport medicine can be an area SPCs struggle with, building effective working relationships with treatment providers can help promote and increase SPCs involvement in providing holistic, interprofessional care to athletes with injuries. To ensure athletes' successful biopsychosocial return to sport, different individuals and professionals should work together for the benefit of the athlete by adopting holistic care during sports injury rehabilitation.

The aim of this study was to quantify the physiological responses, time-motion characteristics, and technical executions associated with a novel non-sport-specific small-sided game (SSG) in young team sport players. On 6 separate occasions, 12 young male team sport athletes (mean ± SD: age, 13.0 ± 0.3 years; height, 157.4 ± 4.9 cm; body mass, 47.0 ± 5.0 kg; and V[Combining Dot Above]O2peak, 55.1 ± 4.6 ml·kg·min) completed various "bucketball" SSG formats (i.e., 3 vs. 3, 4 vs. 4, and 6 vs. 6) twice each. Heart rate (HR) was measured during each SSG at 5-second intervals. Time-motion characteristics were measured using global positioning systems. Ratings of perceived exertion (RPEs) were recorded immediately after the SSGs using the Borg scale (RPEs, 6-20). Technical skill executions were measured using a high-speed digital video camera. Analysis revealed a tendency for the 3 vs. 3 games to elicit higher HRs (88.3 ± 4.3) than either 4 vs. 4 (85.9 ± 4.9) or 6 vs. 6 formats (85.9 ± 3.2). Total distance traveled at 13-17.9 km·h was more during 6 vs. 6 than 3 vs. 3 games (very likely substantial true difference, 97%), and total possessions and number of catches, passes, and shots were all higher in 3 vs. 3 compared with 4 vs. 4 and 6 vs. 6 games. There was no difference in RPE between the game formats. The results of this study indicate that 3 vs. 3 non-sport-specific SSGs provide higher stimulus for aerobic fitness adaptation and technical improvement than 4 vs. 4 and 6 vs. 6 formats, and their use for training young team sport athletes is recommended.

Strength training for athletes: does it really help sports performance?

McGuigan, Michael R; Wright, Glenn A; Fleck, Steven J

2012-03-01

The use of strength training designed to increase underlying strength and power qualities in elite athletes in an attempt to improve athletic performance is commonplace. Although the extent to which strength and power are important to sports performance may vary depending on the activity, the associations between these qualities and performance have been well documented in the literature. The purpose of this review is to provide a brief overview of strength training research to determine if it really helps improve athletic performance. While there is a need for more research with elite athletes to investigate the relationship between strength training and athletic performance, there is sufficient evidence for strength training programs to continue to be an integral part of athletic preparation in team sports.

Athletes and coaches at all competitive levels will utilize sports performance and psychiatric services at very high rates if the services are offered on-site and free of charge and are broad in scope and culturally sensitive. Services should be available throughout the team year and cover areas such as team building, mental preparation, stress control, substance prevention, sleep and energy regulation, injury recovery, crisis intervention, and mental disorder treatment. The staff offering these services should be diverse by gender, profession, and culture, and the fees should be paid by the organization. When these services are endorsed by the team's leaders and integrated with the athletic training/medical/player development staff, their utilization will grow quickly and lead to positive outcomes individually and collectively.

Update in the understanding of altitude-induced limitations to performance in team-sport athletes

2013-01-01

The internationalism of field-based team sports (TS) such as football and rugby requires teams to compete in tournaments held at low to moderate altitude (∼1200–2500 m). In TS, acceleration, speed and aerobic endurance are physical characteristics associated with ball possession and, ultimately, scoring. While these qualities are affected by the development of neuromuscular fatigue at sea level, arterial hypoxaemia induced by exposure to altitude may further hinder the capacity to perform consecutive accelerations (CAC) or sprint endurance and thereby change the outcome of a match. The higher the altitude, the more severe the hypoxaemia, and thus, the larger the expected decline in aerobic endurance, CAC and match running performance. Therefore, it is critical for athletes and coaches to understand how arterial hypoxaemia affects aerobic endurance and CAC and the magnitude of decline they may face at altitude for optimal preparation and increased chances of success. This mini review summarises the effects of acute altitude/hypoxia exposure on aerobic endurance, CAC and activity profiles of TS athletes performing in the laboratory and during matches at natural altitude, and analyses the latest findings about the consequences of arterial hypoxaemia on the relationship between peripheral perturbations, neural adjustments and performance during repeated sprints or CAC. Finally, we briefly discuss how altitude training can potentially help athletes prepare for competition at altitude. PMID:24282202

The objective of this research was to assess the psychometric properties of the Sport Satisfaction Instrument (SSI) in a Spanish sample of female athletes in team sports federations, to decide whether it constitutes a valid and reliable instrument to be used in the context of female competitive sport in future research. The SSI was administered to a total of 615 athletes from 12 to 38 yr. of age. Confirmatory procedures and psychometric analysis supported the hypothesized theoretical model of two factors (Satisfaction/fun and Boredom). For female athletes, the 7-item model showed better goodness-of-fit indexes upon eliminating Item 2 from the Boredom subscale. Concurrent validity was explored through the correlations with the Perception of Success Questionnaire and Sport Commitment, obtaining positive correlations between Satisfaction/fun and Task Orientation and Sport Commitment, whereas Boredom correlated positively but less closely with Ego Orientation. The importance of Satisfaction/fun in the prediction of Sport Commitment, starting from task orientation, is emphasized.

The effects of acute ingestion of caffeine on short-duration high-intensity performance are equivocal, while studies of novel modes of delivery and the efficacy of low doses of caffeine are warranted. The aims of the present study were to investigate the effect of acute ingestion of caffeinated chewing gum on repeated sprint performance (RSP) in team sport athletes, and whether habitual caffeine consumption alters the ergogenic effect, if any, on RSP. A total of 18 male team sport athletes undertook four RSP trials using a 40-m maximum shuttle run test, which incorporates 10 × 40-m sprints with 30 s between the start of each sprint. Each participant completed two familiarization sessions, followed by caffeine (CAF; caffeinated chewing gum; 200 mg caffeine) and placebo (PLA; noncaffeinated chewing gum) trials in a randomized, double-blind manner. RSP, assessed by sprint performance decrement (%), did not differ (p = .209; effect size = 0.16; N = 18) between CAF (5.00 ± 2.84%) and PLA (5.43 ± 2.68%). Secondary analysis revealed that low habitual caffeine consumers (<40 mg/day, n = 10) experienced an attenuation of sprint performance decrement during CAF relative to PLA (5.53 ± 3.12% vs. 6.53 ± 2.91%, respectively; p = .049; effect size = 0.33); an effect not observed in moderate/high habitual caffeine consumers (>130 mg/day, n = 6; 3.98 ± 2.57% vs. 3.80 ± 1.79%, respectively; p = .684; effect size = 0.08). The data suggest that a low dose of caffeine in the form of caffeinated chewing gum attenuates the sprint performance decrement during RSP by team sport athletes with low, but not moderate-to-high, habitual consumption of caffeine.

This study has been conducted with the aim of ascertaining the relationship between peer leaders in sport teams and the levels of burnout experienced by their team-mates. A total of 219 Spanish athletes involved in football and basketball participated in the study. To measure leadership among peers, we employed the Sports Peer Leadership Scale, which comprises 24 items, grouped into 6 primary factors: empathy, influence on decision making, sports values, social support, training orientation and competition orientation. And to measure burnout, we employed the Athlete Burnout Questionnaire, which comprises 15 items which are indicators of physical and emotional exhaustion, devaluation and reduced sense of accomplishment among athletes. The results led to the conclusion that there is a statistically significant negative relationship between perceived leadership capacity and the levels of burnout experience by a team. The greater the level of leadership capacity perceived, the lower the levels of burnout will be. A multiple regression analysis with total burnout as dependent variable and social and task orientations of the leader as predictors showed standardized regression coefficients of -.241 (p = .010) and -.076 (p = .413), respectively for social and task orientation, being the effect size equal to .089.

Coverage of high school football by orthopedic sports medicine specialists is considered standard of care in many localities. Determining the economic viability of this endeavor has never been investigated. The primary purpose of the present investigation was to perform an economic analysis of local high school sports coverage by an orthopedic sports medicine practice. From January 2010 to June 2012, a prospective injury report database was used to collect sports injuries from five high school athletic programs covered by a single, private orthopedic sports medicine practice. Patients referred for orthopedic care were then tracked to determine expected cost of care (potential revenue). Evaluation and management codes and current procedure terminology codes were obtained to determine the value of physician visits and surgical care rendered. Overhead costs were calculated based on historical rates within our practice and incorporated to determine estimated profit. 19,165 athletic trainer contacts with athletes playing all sports, including both those 'on-field' and in the training room, resulted in 473 (2.5%) physician referrals. The covering orthopedic practice handled 89 (27.9%) of the orthopedic referrals. Of orthopedic physician referrals, 26 (5.4%) required orthopedic surgical treatment. The covering team practice handled 17/26 (65%) surgical cases. The total revenue collected by the covering team practice was $26,226.14. The overhead cost of treatment was $9441.41. Overall estimated profit of orthopedic visits and treatment during this period for the covering practice was $16,784.73. The covering team practice handled 28% of the orthopedic referrals, 65% of the surgical cases and captured 59% of the potential profit. An increase in physician referrals could increase the benefit for orthopedic surgeons.

Context The combination of extensive weight loss and inadequate nutritional strategies used to lose weight rapidly for competition in weight-category sports may negatively affect athletic performance and health. Objective To explore the reasoning of elite combat-sport athletes about rapid weight loss and regaining of weight before competitions. Design Qualitative study. Setting With grounded theory as a theoretical framework, we employed a cross-examinational approach including interviews, observations, and Internet sources. Sports observations were obtained at competitions and statements by combat-sport athletes were collected on the Internet. Patients or Other Participants Participants in the interviews were 14 Swedish national team athletes (9 men, 5 women; age range, 18 to 36 years) in 3 Olympic combat sports (wrestling, judo, and taekwondo). Data Collection and Analysis Semistructured interviews with 14 athletes from the Swedish national teams in wrestling, judo, and taekwondo were conducted at a location of each participant's choice. The field observations were conducted at European competitions in these 3 sports. In addition, interviews and statements made by athletes in combat sports were collected on the Internet. Results Positive aspects of weight regulation other than gaining physical advantage emerged from the data during the analysis: sport identity, mental diversion, and mental advantage. Together and individually, these categories point toward the positive aspects of weight regulation experienced by the athletes. Practicing weight regulation mediates a self-image of being “a real athlete.” Weight regulation is also considered mentally important as a part of the precompetition preparation, serving as a coping strategy by creating a feeling of increased focus and commitment. Moreover, a mental advantage relative to one's opponents can be gained through the practice of weight regulation. Conclusions Weight regulation has mentally important functions

Athlete external load is typically analysed from predetermined movement thresholds. The combination of movement sequences and differences in these movements between playing positions is also currently unknown. This study developed a method to discover the frequently recurring movement sequences across playing position during matches. The external load of 12 international female netball athletes was collected by a local positioning system during four national-level matches. Velocity, acceleration and angular velocity were calculated from positional (X, Y) data, clustered via one-dimensional k-means and assigned a unique alphabetic label. Combinations of velocity, acceleration and angular velocity movement were compared using the Levenshtein distance and similarities computed by the longest common substring problem. The contribution of each movement sequence, according to playing position and relative to the wider data set, was then calculated via the Minkowski distance. A total of 10 frequently recurring combinations of movement were discovered, regardless of playing position. Only the wing attack, goal attack and goal defence playing positions are closely related. We developed a technique to discover the movement sequences, according to playing position, performed by elite netballers. This methodology can be extended to discover the frequently recurring movements within other team sports and across levels of competition.

Caffeine can be a powerful ergogenic aid for the performance of prolonged, submaximal exercise. Little evidence, however, supports an ergogenic effect of caffeine on intermittent-sprint performance. Hence, this study was conducted to examine the effects of acute caffeine ingestion on prolonged intermittent-sprint performance. Using a double-blind, placebo-controlled design, 10 male team-sport athletes (amateur level, VO2peak 56.5 +/- 8.0 mL x kg(-1) x min(-1)) completed two exercise trials, separated by 7 d, 60 min after ingestion of either 6 mg x kg(-1) caffeine or placebo. The exercise trial was performed on a front-access cycle ergometer and consisted of 2 x 36-min halves, each composed of 18 x 4-s sprints with 2-min active recovery at 35% VO2peak between each sprint. Urinary caffeine levels were measured after exercise. The total amount of sprint work performed during the caffeine trial was 8.5% greater than that performed during the placebo trial in the first half (75,165.4 +/- 3,902.9 vs 69,265.6 +/- 3,719.7 J, P < 0.05), and was 7.6% greater in the second half (73,978.7 +/- 4,092.6 vs 68,783.2 +/- 3,574.4 J, P < 0.05). Similarly, the mean peak power score achieved during sprints in the caffeine trial was 7.0% greater than that achieved during the placebo trial in the first half (1330.9 +/- 68.2 vs 1244.2 +/- 60.7 W, P < 0.05), and was 6.6% greater in the second half (1314.5 +/- 68.4 vs 1233.2 +/- 59.9 W, P < 0.05). Urinary caffeine levels following the caffeine trial ranged from 3.5 to 9.1 microg x mL(-1) (6.9 +/- 0.6 microg x mL(-1)). This study revealed that acute caffeine ingestion can significantly enhance performance of prolonged, intermittent-sprint ability in competitive, male, team-sport athletes.

Athlete self-report measures (ASRM) are a popular method of athlete monitoring in high-performance sports. With increasing recognition and accessibility, ASRM may potentially be utilized by athletes from diverse sport contexts. The purpose of the present study was to improve understanding of ASRM implementation across different sport contexts by observing uptake and compliance of a newly implemented ASRM over 16 weeks, and investigating the perceived roles and factors influencing implementation. Athletes (n=131) completed an electronic survey at baseline and week 16 on their perceptions and experiences with ASRM implementation respectively. Despite initial interest, only 70 athletes attempted to use the ASRM. Of these athletes, team sport athletes who were supported by their coach or sports program to use the ASRM were most compliant (p < 0.001) with a mean compliance of 84 ± 21 %. Compliance for self-directed individual and team sport athletes was 28 ± 40 % and 8 ± 18 % respectively. Self-directed athletes were motivated to monitor themselves, and rated desired content and minimal burden as key factors for initial and ongoing compliance. Supported athletes were primarily motivated to comply for the benefit of their coach or sports program rather than themselves, however rated data output as a key factor for their continued use. Factors of the measure outweighed those of the social environment regardless of sport context, however the influence of social environmental factors should not be discounted. The findings of the present study demonstrate the impact of sport context on the implementation of an ASRM and the need to tailor implementation strategies accordingly. Key points Athletes perceive ASRM and the factors influencing implementation differently. Therefore, to encourage compliance, it is important to tailor implementation strategies to the athlete and their sport context to increase appeal and minimize unappealing factors.

Religiousness is known to be specifically associated with substance abuse, but there is an evident lack of studies investigating the association between religiousness and doping behavior as a specific type of substance abuse in athletes. This study aimed to provide evidence for possible gender- and sport-specific associations between religiousness and doping behavior among team-sport athletes of both genders. The participants were 886 athletes (21.9 ± 3.8 years of age; 352 females) involved in four sports: volleyball (n = 154; 78 females), handball (n = 206; 68 females), soccer (n = 316; 110 females) and basketball (n = 230; 96 females) from Croatia and Slovenia (all traditionally Roman Catholics). The data were collected using a previously validated structured questionnaire that examined sociodemographic, sport- and doping-related factors. In addition, religiousness was captured by the Santa Clara Strength of Religious Faith questionnaire (SCSRF). Gender-stratified simple logistic regressions were applied to determine associations between covariates and doping behavior (criterion). There was no significant difference in potential doping behavior between males and females (OR 1.06, 95 % CI 0.76-1.46), while females reported higher religiousness (SCSRF: 23.11 ± 3.23 and 25.46 ± 7.2 for males and females, respectively; t test = 1.82, p < 0.05). Younger female athletes and those with higher SCSRF score are found to be less prone to doping behavior. When models were adjusted for personal opinion about doping presence in sport and age, the SCSRF remained a significant predictor of potential doping behavior (OR 0.95, 95 % CI 0.91-0.99). For males, the belief that doping was present in sport was strongly associated with a higher likelihood of doping. Our results suggest that highly religious females involved in three of the studies sports (i.e., volleyball, handball and basketball) show a weaker tendency toward doping. Meanwhile, there is no

Elite athletes require the most advanced sports equipment to maintain their competitive edge, but manufacturers cannot always satisfy these athletes' specific equipment needs. Sport involvement can influence sports-equipment selections and is described as the process by which individuals rely on attitudes and belief systems to make sports-related consumption decisions. This study involved semistructured interviews with 5 elite Parasport athletes to identify and analyze the role of sport involvement in their selection of sports equipment. The results revealed that the athletes identified product limitations, created a collaborative environment, and promoted a culture of innovation to develop new sports products and address existing limitations. Theoretical and practical implications are discussed.

There is increased growth in sports participation across the globe. Sports specialization patterns, which include year-round training, participation on multiple teams of the same sport, and focused participation in a single sport at a young age, are at high levels. The need for this type of early specialized training in young athletes is currently under debate. Nonsystematic review. Clinical review. Level 4. Sports specialization is defined as year-round training (greater than 8 months per year), choosing a single main sport, and/or quitting all other sports to focus on 1 sport. Specialized training in young athletes has risks of injury and burnout, while the degree of specialization is positively correlated with increased serious overuse injury risk. Risk factors for injury in young athletes who specialize in a single sport include year-round single-sport training, participation in more competition, decreased age-appropriate play, and involvement in individual sports that require the early development of technical skills. Adults involved in instruction of youth sports may also put young athletes at risk for injury by encouraging increased intensity in organized practices and competition rather than self-directed unstructured free play.

Certified athletic trainers (ATs) are responsible for integrating relevant professionals into the rehabilitation team to assist with the holistic care of injured athletes. To explore National Collegiate Athletic Association Division I (DI) ATs' experience with sport psychology consultants (SPCs), willingness to encourage athletes to use SPCs for injury rehabilitation, and perceptions of the benefits of sport psychology services. Quantitative study. A Web-based survey was administered to a national sample of DI ATs. A total of 659 (341 men, 318 women) ATs completed the survey. Athletic trainers' experience with SPCs, willingness to encourage athletes to seek sport psychology services, and perceptions of the benefits of those services in injury-rehabilitation settings were self-reported using a rating scale that ranged from 1 (never or not at all) to 5 (definitely or extremely). Logistic regression revealed that the availability of SPCs, previous encouragement to athletes to seek sport psychology services, and previous positive interactions with SPCs predicted the ATs' willingness to encourage athletes to use these services (P < .0001). The services ATs rated the highest for injury rehabilitation were managing anxiety and emotion, improving coping techniques, and building confidence (ie, confidence in returning to sport and building confidence). Chi-square analyses indicated that female ATs' ratings of perceived benefits were higher (P ≤ .001) than those of male ATs, and the ratings of ATs who were likely to encourage the use of SPCs were higher (P ≤ .001) than those who were unlikely to encourage SPC service use. Athletic trainers in our study who had previous positive SPC experiences were most likely to use SPCs and their services during the injury-rehabilitation process. Possible implications are offered for how ATs interested in sport psychology services might call on SPCs to complement their work with injured athletes.

Data analysis was guided by the consensual qualitative research tradition. Themes and categories emerged through consensus by a 3-person research team, and bias was minimized through the use of multiple-analyst triangulation. Participants identified numerous postconcussion symptoms that resulted in increasing difficulty with emotions (eg, irritable, easily frustrated), roles at school (eg, concentration difficulties, fatigue), and roles in their social environment (eg, letting the team down, not being able to contribute to sport). As a result, participants expressed how they tried to minimize or mask symptoms to decrease the potential of being viewed differently by their peers. Adolescent athletes perceived a significant effect of sport-related concussion on numerous areas of psychosocial and emotional health and well-being.

The aim of this study was to evaluate whether the distribution of polymorphisms in the ACE, ACTN3, NOS3, UCP2, and UCP3 genes, which has been reported to be correlated with different physiological parameters, played a role in sport performance. We focused on a cohort of 82 Italian athletes: first of all, athletes were divided according to type of sport: team (n=72) versus individual (n=10), and subsequently, according to the performance, into "power" sports (n=29; sprinters, short distance swimmers, and volleyball players) and "intermittent" sports (n=53; football, basketball, and hockey players). All the populations studied were in Hardy-Weinberg equilibrium for the following polymorphisms: ACE (I/D), ACTN3 (R577X), NOS3 (-786 T/C), UCP2 (A55V), and UCP3 (-55 C/T). We observed that the frequency of NOS3-786 T and UCP2 C alleles was higher among power athletes compared with controls (p=0.011 and p=0.012, respectively); these alleles were also overrepresented in individual athletes (p=0.02 and p=0.045, respectively), although a small sample was analyzed. The frequency of NOS3 298G allele was higher among power athletes compared with controls (p=0.015); these data remained suggestive after correction for multiple testing. We found a suggestive association between NOS3 (-786 T/C; G298A) and UCP2 (A55V) polymorphisms and power athletes, whereas no significant correlation was found with UCP3 (-55C/T), ACE (I/D), and ACTN3 (R577X) polymorphisms, in contrast to previous studies. Analysis of multiple performance-associated genetic polymorphisms needs further examination to explain the relationship between genetic background and potential success in sport performance.

To a proper recovery, is absolutely necessary to know that athletes with enhanced recovery after maximal exercise are likely to perform better in sports. Recovery strategies are commonly used in team sports despite limited scientific evidence to support their effectiveness in facilitating optimal recovery and the players spend a much greater proportion of their time recovering than they do in training. According to authors, some studies investigated the effect of recovery strategies on physical performance in team sports, lack of experimental studies about the real origin of the fatigue, certify the need for further study this phenomenon. Thus, developing effective methods for helping athletes to recover is deemed essential. Therefore, the aim of this review is provide information for his practical application, based on scientific evidence about recovery in team sports.

The integration of chiropractors into healthcare teams: a case study from sport medicine.

PubMed

Theberge, Nancy

2008-01-01

This article examines the integration of chiropractors into multi-disciplinary healthcare teams in the specialisation of sport medicine. Sport medicine is practised in a number of contexts in professional and amateur sport. The current analysis focuses on the highest levels of amateur sport, as exemplified by the Olympics. Data are taken from interviews with 35 health professionals, including physicians, physiotherapists, athletic therapists and chiropractors. A defining feature of sport medicine is an emphasis on performance, which is the basis for a client-centred model of practice. These two elements have provided the main grounds for the inclusion of chiropractic in sport medicine. While the common understanding that 'athletes wanted them' has helped to secure a position for chiropractic within the system of sport medicine professions, this position is marked by ongoing tensions with other professions over the scope and content of practice, and the nature of the patient-practitioner relationship. In the context of these tensions, chiropractors' success in achieving acceptance on sport medicine teams is contingent on two factors: (a) reduced scope of practice in which they work primarily as manual therapists; and (b) the exemplary performance of individual practitioners who 'fit' into multi-disciplinary sport medicine teams.

Athletic pubalgia or sports hernia is a syndrome of chronic lower abdomen and groin pain that may occur in athletes and nonathletes. Because the differential diagnosis of chronic lower abdomen and groin pain is so broad, only a small number of patients with chronic lower abdomen and groin pain fulfill the diagnostic criteria of athletic pubalgia (sports hernia). The literature published to date regarding the cause, pathogenesis, diagnosis, and treatment of sports hernias is confusing. This article summarizes the current information and our present approach to this chronic lower abdomen and groin pain syndrome. Copyright © 2011 Elsevier Inc. All rights reserved.

Sports Specialization in Young Athletes

Jayanthi, Neeru; Pinkham, Courtney; Dugas, Lara; Patrick, Brittany; LaBella, Cynthia

2013-01-01

Context: Sports specialization is intense training in 1 sport while excluding others. Sports specialization in early to middle childhood has become increasingly common. While most experts agree that some degree of sports specialization is necessary to achieve elite levels, there is some debate as to whether such intense practice time must begin during early childhood and to the exclusion of other sports to maximize potential for success. There is a concern that sports specialization before adolescence may be deleterious to a young athlete. Evidence Acquisition: PubMed and OVID were searched for English-language articles from 1990 to 2011 discussing sports specialization, expert athletes, or elite versus novice athletes, including original research articles, consensus opinions, and position statements. Results: For most sports, there is no evidence that intense training and specialization before puberty are necessary to achieve elite status. Risks of early sports specialization include higher rates of injury, increased psychological stress, and quitting sports at a young age. Sports specialization occurs along a continuum. Survey tools are being developed to identify where athletes fall along the spectrum of specialization. Conclusion: Some degree of sports specialization is necessary to develop elite-level skill development. However, for most sports, such intense training in a single sport to the exclusion of others should be delayed until late adolescence to optimize success while minimizing injury, psychological stress, and burnout.

Effect of motivational climate profiles on motivational indices in team sport.

PubMed

Ommundsen, Y; Roberts, G C

1999-12-01

Contemporary perspectives of achievement motivation have been based on social cognitive theories which give motivational climate a central place in the regulation of subsequent affective states, cognitions and behaviour in achievement contexts. This study examined the relationship between different profiles of the motivational climate in teamsport and achievement, and socially related cognitions among Norwegian team sport athletes. Players (N= 148) assessed their perception of the motivational climate using the Norwegian version of the Motivational climate in sport questionnaire, sources of satisfaction in team sport, achievement strategies, perceived purposes of sport, and conceptions of ability. Multivariate analysis of variance (2x2) showed both main effects for profiles of the motivational climate and an interaction effect. Athletes perceiving the climate as high in mastery and high in performance oriented criteria reported psychological responses that were more adaptative than those perceiving the climate as low in mastery and high in performance criteria. With one exception, the findings showed that those high in mastery and low in performance were more likely to emphasise self-referenced criteria when judging perceived ability in team sport. For both social responsibility and lifetime skills as purposes in sport, it was the high performance and low mastery athletes who were least likely to endorse these purposes. And importantly, the high mastery climate seemed to moderate the impact of being in a high performance climate. The pattern of findings suggests that perceiving the motivational climate as performance oriented may not be motivationally maladaptive when accompanied by mastery oriented situational cues.

White cell counts at rest might be lower in athletes participating in selected endurance-type sports. Here, we analysed blood tests of elite athletes collected over a 10-year period. Reference ranges were established for 14 female and 14 male sports involving 3,679 samples from 937 females and 4,654 samples from 1,310 males. Total white blood cell counts and counts of neutrophils, lymphocytes and monocytes were quantified. Each sport was scaled (1-5) for its perceived metabolic stress (aerobic-anaerobic) and mechanical stress (concentric-eccentric) by 13 sports physiologists. Substantially lower total white cell and neutrophil counts were observed in aerobic sports of cycling and triathlon (~16% of test results below the normal reference range) compared with team or skill-based sports such as water polo, cricket and volleyball. Mechanical stress of sports had less effect on the distribution of cell counts. The lower white cell counts in athletes in aerobic sports probably represent an adaptive response, not underlying pathology.

In team sports, athletes' goals may focus on the task (enhancing performance, developing better skills, etc.) or on ego (being better than the others, achieving superiority, etc.). This study investigated the relationships between athletes' goal orientation and their tendency to cooperate with teammates and coaches. 158 professional men (M age = 24.1 yr., SD = 4.6) who played on various sport teams participated in this study. Goal orientation was measured with the Portuguese version of the Task and Ego Orientation in Sport Questionnaire, and cooperation was measured with the Questionário de Cooperação Desportiva. Cooperation was positively correlated with task orientation, and negatively correlated with ego orientation. Overall, the findings support that in sports, directing the players' focus on task may promote prosocial behavior.

Talent development of high performance coaches in team sports in Ireland.

Coaches are central to the development of the expert performer and similarly to continued lifelong participation in sport. Coaches are uniquely positioned to deliver specific technical and tactical instruction and mentoring programmes that support the psychological and social development of athletes in a challenging, goal-oriented and motivational environment. The current study aimed to qualitatively investigate current coach learning sources and coaches' educational backgrounds in team sports in Ireland. Coaches from five team sports in Ireland were asked to complete an online questionnaire. Subsequently male coaches (n = 19) from five team sports who completed the questionnaire and met the inclusion criteria were invited to attend a follow-up semi-structured interview. Inclusion criteria for coaches were that they possess at least 10 years' experience coaching their sport and were coaching more than 4 hours per week. Formal coach education does not meet the needs of high performance coaches who rely more on self-directed learning and coaching experience as their main sources of CPD. Although prior playing experience at a high level is both valuable and desirable, there are concerns about fast-tracking of ex-players into high performance coaching roles. Preferred sources of education and the best learning environment for coaches of team sports in Ireland are more informal than formal. Further research is needed to examine how this learning is applied in a practical manner by examining coaching behaviours and the impact it has on the athlete development process.

Emotional Intelligence, Motivational Climate and Levels of Anxiety in Athletes from Different Categories of Sports: Analysis through Structural Equations.

(1) Background: Psychological factors can strongly affect the athletes’ performance. Therefore, currently the role of the sports psychologist is particularly relevant, being in charge of training the athlete’s psychological factors. This study aims at analysing the connections between motivational climate in sport, anxiety and emotional intelligence depending on the type of sport practised (individual/team) by means of a multigroup structural equations analysis. (2) 372 semi-professional Spanish athletes took part in this investigation, analysing motivational climate (PMCSQ-2), emotional intelligence (SSRI) and levels of anxiety (STAI). A model of multigroup structural equations was carried out which fitted accordingly (χ² = 586.77; df = 6.37; p < 0.001; Comparative Fit Index (CFI) = 0.951; Normed Fit Index (NFI) = 0.938; Incremental Fit Index (IFI) = 0.947; Root Mean Square Error of Approximation (RMSEA) = 0.069). (3) Results: A negative and direct connection has been found between ego oriented climate and task oriented climate, which is stronger and more differentiated in team sports. The most influential indicator in ego oriented climate is intra-group rivalry, exerting greater influence in individual sports. For task-oriented climate the strongest indicator is having an important role in individual sports, while in team sports it is cooperative learning. Emotional intelligence dimensions correlate more strongly in team sports than in individual sports. In addition, there was a negative and indirect relation between task oriented climate and trait-anxiety in both categories of sports. (4) Conclusions: This study shows how the task-oriented motivational climate or certain levels of emotional intelligence can act preventively in the face of anxiety states in athletes. Therefore, the development of these psychological factors could prevent anxiety states and improve performance in athletes.

J Strength Cond Res 31(8): 2147-2154, 2017-Low-load resistance training with blood flow restriction (BFR) may be a method to enhance muscular development even in trained athletes. This study aimed to assess whether supplemental low-load BFR training can improve muscle size, strength, and physical performance characteristics in team sport athletes. Twenty-one semiprofessional Australian football athletes were assessed for 3-repetition maximum (3RM) and muscular endurance in the back squat, vastus lateralis muscle architecture, and performance in sprint and vertical jump tasks. Participants then undertook a 5-week training program, consisting of normal high-load resistance training supplemented by low-load squats with (LLBFR) or without (LL) BFR. Participants also performed regular conditioning and football training during this period. After the training intervention, participants again completed the pretraining testing battery. Squat 3RM and endurance increased from pretraining levels in both LL (3RM = 12.5% increase; endurance = 24.1% increase; p ≤ 0.007) and LLBFR (3RM = 12.3% increase; endurance = 21.2% increase; p = 0.007) groups, though there were no between-group differences. No post-training changes were observed for muscle architecture, or performance in sprinting and jumping tasks. Although squat 3RM and endurance performance increased in both groups, adding BFR during supplemental exercise did not enhance these responses. Similarly, there were no large differences in the assessments of sprint, acceleration, and jumping performance between the groups after training. These findings suggest that although LLBFR did not negatively affect adaptive responses to resistance training, this training strategy may not provide added benefit for healthy Australian football athletes

The ways in which newcomers are integrated into sport teams may have broad consequences for the athletes entering the group, as well as for the existing team members. Drawing from organizational socialization theory, the current research developed a questionnaire to assess athletes' perceptions of how newcomers are socialized into their group. Across four studies, think-aloud interviews (N = 8), an expert panel review (N = 6), cross-sectional tests of the factor structure (N Study 2  = 197; N Study 3  = 460), and a two-wave correlational design (N Study 4  = 194) were used to evaluate the construct validity and the internal consistency of the Sport Team Socialization Tactics Questionnaire (STSTQ). Collectively, these efforts identified a three-factor structure underlying the STSTQ and provided preliminary evidence for its validity. The STSTQ enables researchers to systematically examine the individual- and group-level consequences associated with the socialization tactics implemented in sport teams.

Sport provides a context in which mate choice can be facilitated by the display of athletic prowess. Previous work has shown that, for females, team sport athletes are more desirable as mates than individual sport athletes and non-participants. In the present study, the perceptions of males and females were examined regarding potential mates based on sport participation. It was predicted that team sport athletes would be more positively perceived than individual sport athletes and non-participants by both males and females. A questionnaire, a photograph, and manipulated descriptions were used to gauge perceptual differences with respect to team sport athletes, individual sport athletes, and extra-curricular club participants for 125 females and 119 males from a Canadian university. Both team and individual sport athletes were perceived as being less lazy, more competitive, and healthier than non-participants by both males and females. Interestingly, females perceived male athletes as more promiscuous than non-athletes, which upholds predictions based on previous research indicating (a) athletes have more sexual partners than non-athletes, and (b) females find athletes more desirable as partners than non-participants. Surprisingly, only males perceived female team sport athletes as more dependable than non-participants, and both team and individual sport athletes as more ambitious. This raises questions regarding the initial hypothesis that male team athletes would be perceived positively by females because of qualities such as the ability to cooperate, likeability, and the acceptance of responsibilities necessary for group functioning. Future studies should examine similar questions with a larger sample size that encompasses multiple contexts, taking into account the role of the social profile of sport in relation to mate choice and perception.

Sport specialization has been associated with overuse injuries and is more common in larger high schools, which are often located in more urban/suburban settings. However, sport participation characteristics have not been compared between suburban and rural high schools. The purpose of this study was to examine the differences in sport participation characteristics between athletes at suburban and rural high schools. It was hypothesized that suburban high school students would be more likely to be highly specialized, participate in more athletic competitions per year, and play in a league outside of school. We also hypothesized that suburban high school students would start playing their primary sport at a younger age, would have participated in their primary sport for longer, and would play more months per year and hours per week. Cross-sectional study. High school athletes from 4 high schools (2 suburban and 2 rural) participated in this study (N = 354 [222 females]; mean age, 15.7 ± 1.2 years). Athletes were on a school-sponsored athletic team in 1 of 4 sports (volleyball, tennis, basketball, soccer). The suburban schools (study enrollment, n = 226) had total school enrollments of 2271 and 622 students, while the rural schools (study enrollment, n = 128) had total school enrollments of 443 and 297. Participants completed a questionnaire prior to the start of their high school sport season. The questionnaire consisted of demographic information, a sport specialization scale, and sport participation information. Primary sport competition volume in the previous 12 months was classified as high (>60 primary sport competitions), moderate (30-60), or low (<30). Sport specialization status was classified via a 3-point scale as low, moderate, or high. As compared with athletes at rural schools, athletes at suburban schools started playing their primary sport at a younger age (suburban, 7.8 ± 2.9 years; rural, 9.7 ± 3.2 years; P < .001) and participated for more years

Competitiveness and the Process of Co-adaptation in Team Sport Performance.

PubMed

Passos, Pedro; Araújo, Duarte; Davids, Keith

2016-01-01

An evolutionary psycho-biological perspective on competitiveness dynamics is presented, focusing on continuous behavioral co-adaptations to constraints that arise in performance environments. We suggest that an athlete's behavioral dynamics are constrained by circumstances of competing for the availability of resources, which once obtained offer possibilities for performance success. This defines the influence of the athlete-environment relationship on competitiveness. Constraining factors in performance include proximity to target areas in team sports and the number of other competitors in a location. By pushing the athlete beyond existing limits, competitiveness enhances opportunities for co-adaptation, innovation and creativity, which can lead individuals toward different performance solutions to achieve the same performance goal. Underpinned by an ecological dynamics framework we examine whether competitiveness is a crucial feature to succeed in team sports. Our focus is on intra-team competitiveness, concerning the capacity of individuals within a team to become perceptually attuned to affordances in a given performance context which can increase their likelihood of success. This conceptualization implies a re-consideration of the concept of competitiveness, not as an inherited trait or entity to be acquired, but rather theorizing it as a functional performer-environment relationship that needs to be explored, developed, enhanced and maintained in team games training programs.

Cross-sectional. To describe performance and asymmetry on the Star Excursion Balance Test (SEBT) by sex and sport, and to determine if differences exist within a collegiate athlete population. Performance on the SEBT may differ between sexes and levels of competition, though the results of previous studies have been inconsistent. Investigation of performance and asymmetry differences between sports is limited. Sex- and sport-specific reference values likely need to be determined to best assess SEBT performance. Performance on the SEBT was retrospectively reviewed in 393 healthy National Collegiate Athletic Association Division I collegiate athletes from 8 sports. Means, standard deviations, and 95% confidence intervals were calculated for all variables. Normalized reach distance (percent limb length) and asymmetry between limbs were compared for the anterior (ANT), posterolateral (PL), and posteromedial (PM) directions and for the composite (COMP) score using a 2-way analysis of variance (ANOVA) of sex by sport, and a 1-way ANOVA to separately compare sports within each sex. Average normalized reach distance ranged from 62% to 69%, 84% to 97%, and 99% to 113% in the ANT, PL, and PM directions, respectively, and from 82% to 92% in the COMP score. Normalized asymmetry ranged from 3% to 4%, 5% to 8%, and 5% to 6% in the ANT, PL, and PM directions, respectively. A significant sex-by-sport interaction (P = .039) was observed in the ANT direction, with a sex effect for soccer players (P<.001; men less than women). Significant differences were observed in the PL and PM directions and in the COMP score among women's teams, with women's ice hockey players reaching the farthest (COMP, 90.0%). Among men's teams, significant differences were observed in all directions and in the COMP score. Men's ice hockey players (COMP, 91.9%) and wrestlers achieved the farthest distances (COMP, 88.8%). Performance on the SEBT varies by team, with a difference between sexes also present for

The recognition of sports medicine and promulgation of practice guidelines for team physicians will push general medical malpractice standards to evolve into a more specialized standard of care for those who practice in this area. To the extent that practicing medicine in the sports context involves calculations that do not arise in typical medical practice, the sports medicine community can help elucidate those issues and create appropriate guidelines that can serve to inform athlete-patients and educate courts. Doing so will help best set the terms by which those who practice sports medicine are judged. Copyright © 2016 Elsevier Inc. All rights reserved.

The food and weight combat. A problematic fight for the elite combat sports athlete.

Weight reduction in athletes is motivated by optimisation of performance, aesthetic reasons or to achieve a pre-designated weight. Previous research has shown that dietary restraint and short term weight regulation frequently takes place among combat sports athletes such as wrestlers and judokas. The aim of this study was to explore negative experiences related to dietary strategies and weight-making practises used by elite combat sports athletes. Using semi-structured interviews, 14 Swedish national team athletes in wrestling, judo and taekwondo were asked about their dietary intake and their engagement in both long- and short-term weight regulation practises. Content analysis of the transcribed interviews, display a constant struggle regarding nutritional standpoints. Sport demands such as achieving an optimal weight and nutritional intake were considered as central in order for excellent performance. Adhering to these demands was found to be problematic however, primarily because of; (1) negative physiological responses and (2) opposing ideals of a non-sport related nature, such as the importance of the athletes to be healthy and social in their everyday lives.

This paper presents an overview of the Husky Sport Nutrition Program at the University of Washington. This program is a component of the Department of Intercollegiate Athletics Total Student-Athlete Program, an NCAA-sponsored CHAMPS/Life Skills Program that provides life skills assistance to student-athletes. Successful integration of a sport nutrition program requires an understanding of the athletic culture, physiological milestones, and life stressors faced by college athletes. The sport nutritionist functions as an educator, counselor, and administrator. Team presentations and individual nutrition counseling provide athletes with accurate information on healthy eating behaviors for optimal performance. For women's sports, a multidisciplinary team including the sport nutritionist, team physician, clinical psychologist, and athletic trainer work to prevent and treat eating disorders. Case studies are presented illustrating the breadth of nutrition-related issues faced by a sport nutritionist working with college athletes.

White, Sally A; Kavussanu, Maria; Tank, Kari M; Wingate, Jason M

2004-02-01

This study examined the relationship between perceived parental beliefs and young athletes' achievement goal orientations and personal beliefs about the causes of success in sport. Participants were 183 male and female athletes, 11-18 years old, involved in team sports. Athletes completed the Task and Ego Orientation in Sport Questionnaire, the Beliefs about the Causes of Sport Success Questionnaire, and two modified versions of the latter inventory to assess their perceptions of their parents' beliefs. Canonical correlation analysis revealed that perceived parental beliefs were related to goal orientations and personal beliefs in a conceptually coherent fashion. Thus, the perceived parental belief that effort leads to success in sport was related to athletes' task orientation and personal belief that effort causes sport success. In contrast, the perceived parental beliefs that superior ability, external factors, and using deceptive tactics are precursors to success in sport corresponded to athletes' ego orientation and the same personal beliefs. The findings are discussed in terms of their implications for understanding the socialization experiences of young athletes.

Doping in sport: a review of elite athletes' attitudes, beliefs, and knowledge.

Morente-Sánchez, Jaime; Zabala, Mikel

2013-06-01

Doping in sport is a well-known phenomenon that has been studied mainly from a biomedical point of view, even though psychosocial approaches are also key factors in the fight against doping. This phenomenon has evolved greatly in recent years, and greater understanding of it is essential for developing efficient prevention programmes. In the psychosocial approach, attitudes are considered an index of doping behaviour, relating the use of banned substances to greater leniency towards doping. The aim of this review is to gather and critically analyse the most recent publications describing elite athletes' attitudes, beliefs and knowledge of doping in sport, to better understand the foundations provided by the previous work, and to help develop practical strategies to efficiently combat doping. For this purpose, we performed a literature search using combinations of the terms "doping", "sport", "elite athletes", "attitudes", "beliefs", "knowledge", "drugs", and "performance-enhancing substances" (PES). A total of 33 studies were subjected to comprehensive assessment using articles published between 2000 and 2011. All of the reports focused on elite athletes and described their attitudes, beliefs and knowledge of doping in sport. The initial reasons given for using banned substances included achievement of athletic success by improving performance, financial gain, improving recovery and prevention of nutritional deficiencies, as well as the idea that others use them, or the "false consensus effect". Although most athletes acknowledge that doping is cheating, unhealthy and risky because of sanctions, its effectiveness is also widely recognized. There is a general belief about the inefficacy of anti-doping programmes, and athletes criticise the way tests are carried out. Most athletes consider the severity of punishment is appropriate or not severe enough. There are some differences between sports, as team-based sports and sports requiring motor skills could be less

2014-11-01

The present study compares previous reports on the effect of "real-life" typical field individual (i.e., cross-country running and wrestling--representing combat versus noncombat sports) and team sports (i.e., volleyball and water polo-representing water and land team sports) training on GH and IGF-1, the main growth factors of the GH→IGF axis, in male and female late pubertal athletes. Cross-country running practice and volleyball practice in both males and females were associated with significant increases of circulating GH levels, while none of the practices led to a significant increase in IGF-I levels. The magnitude (percent change) of the GH response to the different practices was determined mainly by preexercise GH levels. There was no difference in the training-associated GH response between individual and team sports practices. The GH response to the different typical practices was not influenced by the practice-associated lactate change. Further studies are needed to better understand the effect of real-life typical training in prepubertal and adolescent athletes and their role in exercise adaptations.

2007-01-01

Background The issue of the expectations of elite athletes, their coaches and non‐medically qualified athlete support staff of consultations with sports physicians has not been previously dealt with in the sports medicine literature. As fulfilment of expectations of the content of a consultation may influence patient's satisfaction and clinical outcome, it is important to assess the expectations of athletes and, most importantly, coaches. Objective To assess the expectations and beliefs about fatigue, particularly in relation to blood tests, of athletes, their coaches and support staff in the specific context of tiredness of <7 days' duration. Subjects 28 senior sports science or non‐medically qualified sports medicine staff, 22 elite coaches and 62 elite athletes from the Australian Institute of Sport were included in this study. Methods A single questionnaire. Results The expectation for a blood test at the initial consultation for short‐term fatigue was particularly high among athletes (81%) and coaches (91%). This expectation increased in athletes if their performance was worsening. All groups unanimously suggested that a blood test be performed in cases of more prolonged fatigue. Increase in total training load was perceived to be the most important cause of fatigue, but issues relating to sleep were also thought to be highly relevant. All groups suggested that blood tests provide some degree of reassurance, and all groups suggested that the most important blood tests that might be performed related to exclusion of iron deficiency, anaemia and infection. Conclusion Athletes and their coaches generally expect that blood tests will be performed even when fatigue has been present for <1 week. This is at odds with currently available evidence of the diagnostic utility of these tests. Despite the current evidence base, individual factors in the athletes, coaches and doctors need to be considered when deciding on whether such testing has to be performed

Background In 1992, the concept of female athlete triad was introduced to describe the interrelated problems of amenorrhea, eating disorders and osteoporosis seen in female athletes. To gain a clearer picture of amenorrhea/oligomenorrhea in Iran, one of the main components of the female athlete triad, we therefore established this study on the prevalence of amenorrhea/oligomenorrhea in elite Iranian female athletes, also evaluating the risk factors of these disorders in the same population. Methods This study performed as a cross-sectional study. All elite Iranian female athletes of 34 sports federation, including female athletes in national teams and medalists of Tehran were invited to participate. A total of 788 (95% response rate) returned the questionnaires and were examined. Younger athletes under the age of menarche were excluded. Each athlete completed a self-administered questionnaire, which covered the following questions about participant's demographic information, athletic history, history of injuries and menstrual pattern. In order to diagnose the causes of amenorrhea/Oligomenorrhea including polycystic ovary syndrome(PCOS), participants with amenorrhea/Oligomenorrhea underwent further investigation. They were evaluated by following Para clinic investigation, and an ultrasonographic study of ovary. Results The age ranged from 13–37 (mean = 21.1, SD = 4.5). Seventy one (9.0%) individuals had amenorrhea/oligomenorrhea, among those, 11 (15.5%) had PCOS. There was also a positive association between amenorrhea/oligomenorrhea and the following: age under 20 OR; 2.67, 95%CI(1.47 – 4.85), weight class sports OR; 2.09, 95%CI(1.15 – 3.82), endurance sports OR; 2.89, 95%CI(1.22 – 6.84), late onset of menarche OR; 3.32 95%CI(1.04–10.51), and use of oral contraceptive pills OR; 6.17, 95%CI(3.00 – 12.69).

Researchers have previously reported on the importance of dynamic balance in assessing an individual's risk for injury during sport. However, to date there is no research on whether multiple sport participation affects dynamic balance ability. Therefore, the purpose of this study was to determine if there was a difference in dynamic balance scores in high school athletes that competed in one sport only as compared athletes who competed in multiple sports, as tested by the Lower Quarter Y Balance Test (YBT-LQ). Ninety-two high school athletes who participated in one sport were matched, by age, gender and sport played, to athletes who participated in the same sport as well as additional sports. All individuals were assessed using the YBT-LQ to examine differences in composite reach score and reach direction asymmetry between single sport and multiple sport athletes. The greatest reach distance of three trials in each reach direction for right and left lower-extremities was normalized by limb length and used for analysis. A two-way ANOVA (gender x number of sports played) was used to statistically analyze the variables in the study. No significant interactions or main effects related to number of sports played were observed for any YBT-LQ score (p>0.05). Male athletes exhibited significantly greater normalized reach values for the posteromedial, posterolateral, and composite reach while also exhibiting a larger anterior reach difference when compared to the females. Athletes who participated in multiple sports had similar performances on the YBT-LQ when compared to athletes who participated in a single sport. The findings of this study suggest that the number of sports played by a high school athlete does not need to be controlled for when evaluating dynamic balance with the YBT-LQ.

Sports Hernia/Athletic Pubalgia

2014-01-01

Context: Sports hernia/athletic pubalgia has received increasing attention as a source of disability and time lost from athletics. Studies are limited, however, lacking consistent objective criteria for making the diagnosis and assessing outcomes. Evidence Acquisition: PubMed database through January 2013 and hand searches of the reference lists of pertinent articles. Study Design: Review article. Level of Evidence: Level 5. Results: Nonsurgical outcomes have not been well reported. Various surgical approaches have return-to–athletic activity rates of >80% regardless of the approach. The variety of procedures and lack of outcomes measures in these studies make it difficult to compare one surgical approach to another. There is increasing evidence that there is an association between range of motion–limiting hip disorders (femoroacetabular impingement) and sports hernia/athletic pubalgia in a subset of athletes. This has added increased complexity to the decision-making process regarding treatment. Conclusion: An association between femoroacetabular impingement and athletic pubalgia has been recognized, with better outcomes reported when both are managed concurrently or in a staged manner.

[Purpose] The purpose of our study was to determine the effectiveness of carbohydrate loading by additional carbohydrate supplements for 7 days after prolonged interval exercise on exercise performance and energy metabolism during submaximal exercise in team-sports athletes. [Methods] Twenty male team-sports athletes (14 soccer and 6 rugby players) volunteered to participate in the study and were equally divided into the experimental group (EXP, n=10) performing additional carbohydrate supplementation for 7 days after prolonged interval exercise until blood glucose level reaches 50 mg/dL or less and the control group (CON, n=10). Then, maximal oxygen consumption (VO2max) and minute ventilation (VE), oxygen consumption (VO2), carbon dioxide excretion (VCO2), respiratory exchange ratio (RER), blood glucose level, and blood lactate level were measured in all team-sports players during submaximal exercise corresponding to 70% VO2max before and after intervention. [Results] There was no significant interaction in all parameters, but team-sports players in the EXP presented more improved VO2max (CON vs EXP = vs 5.3% vs 6.3%), VE (CON vs EXP = vs 3.8% vs 6.6%), VO2 (CON vs EXP = vs 8.5% vs 9.9%), VCO2 (CON vs EXP = vs 2.8% vs 4.0%), blood glucose level (CON vs EXP = vs -12.9% vs -7.6%), and blood lactate level (CON vs EXP = -18.2% vs -25%) compared to those in the CON.

Greenfield, Bruce H.; West, Charles Robert

2012-01-01

Ethical issues present a challenge for health care professionals working with athletes of sports teams. Health care professionals—including the team physician, the physical therapist, and the athletic trainer—are faced with the challenge of returning an athlete to competition as quickly as possible but as safely as possible. Conflicts of interest arise due to conflicting obligations of the team physician to the athlete and other members of the sports organization, including coaches and the team owner. The multiple stakeholders involved in sports teams challenge the traditional notion of confidentiality and autonomy. The aims of this article are to explicate the ethics of sports medicine, highlight the ethical issues, and provide some strategies and suggestions for ethical decision making. PMID:24179585

Sports-related injuries in athletes with disabilities.

2014-10-01

The number of athletes with disabilities participating in organized sports and the popularity of the Paralympic Games is steadily increasing around the world. Despite this growing interest and the fact that participation in sports places the athlete at risk for injury, there are few studies concerning injury patterns, risk factors, and prevention strategies of injuries in disabled athletes. In this systematic literature search and critical review, we summarize current knowledge of the epidemiology of sports-related injuries in disabled athletes and describe their characteristics, incidence, prevalence, and prevention strategies. The outcomes of interest were any injury, either an acute trauma or an overuse event. PubMed, EMBASE, CINAHL, and Google Scholar were systematically searched and 25 of 605 identified studies met the inclusion criteria. Lower extremity injuries were more common in walking athletes, whereas upper extremity injuries were more prevalent in wheelchair athletes. The methodologies and populations varied widely between the studies. Few studies were sports or disability specific, which makes it difficult to determine specific risk factors, and few studies reported injury severity and prevention of injuries. Further longitudinal, systematic sports and disability specific studies are needed in order to identify and prevent injuries in athletes with disabilities. © 2014 John Wiley & Sons A/S.

The aim of this study was to analyze all sports injuries incurred in competitions and/or training during the 2007 World Athletics Championships and to prove the feasibility of the injury surveillance system developed for the 2008 Olympic Games for individual sports. Prospective recording of injuries. 11 IAAF World Championships in Athletics 2007 in Osaka, Japan. All national team physicians and physiotherapists; Local Organising Committee (LOC) physicians working in the Medical Centres at the stadium and warm-up area. Frequency, characteristics, and incidence of injuries. 192 injuries were reported, resulting in an incidence of 97 injuries per 1000 registered athletes. More than half of the injuries (56%) were expected to prevent the athlete from participating in competition or training. Eighty percent affected the lower extremity; the most common diagnosis was thigh strain (16%). In most cases, the injury was caused by overuse (44%). A quarter of the injuries were incurred during training and 137 (71%) in competition. On average, 72.4 injuries per 1000 competing athletes were incurred in competitions. The incidence of injury varied substantially among the disciplines. The risk of a time-loss injury was highest in heptathlon, women's 10,000 m, women's 3000 m steeplechase, decathlon, and men's marathon. The injury surveillance system proved feasible for individual sports. Risk of injury varied among the disciplines, with highest risk in combined disciplines, steeplechase, and long-distance runs. Preventive interventions should mainly focus on overuse injuries and adequate rehabilitation of previous injuries.

Sport specialization is a strategy to acquire superior sport performance in 1 sport but is associated with increased injury risk. Currently, the degree of high school specialization among Division I athletes is unknown. College athletes will display increased rates of specialization as they progress through their high school careers. Descriptive epidemiological study. Level 4. Three hundred forty-three athletes (115 female) representing 9 sports from a Midwest Division I University completed a previously utilized sport specialization questionnaire regarding sport participation patterns for each grade of high school. McNemar and chi-square tests were used to investigate associations of grade, sport, and sex with prevalence of sport specialization category (low, moderate, high) (a priori P ≤ 0.05). Specialization increased throughout high school, with 16.9% (n = 58) and 41.1% (n = 141) of athletes highly specialized in 9th and 12th grades, respectively. Football athletes were less likely to be highly specialized than nonfootball athletes for each year of high school ( P < 0.001). There was no difference in degree of specialization between sexes at any grade level ( P > 0.23). The majority of Division I athletes were not classified as highly specialized throughout high school, but the prevalence of high specialization increased as athletes progressed through high school. Nonfootball athletes were more likely to be highly specialized than football athletes at each grade level. Most athletes who are recruited to participate in collegiate athletics will eventually specialize in their sport, but it does not appear that early specialization is necessary to become a Division I athlete. Athletes should be counseled regarding safe participation in sport during high school to minimize injury and maximize performance.

A more horizontally oriented ground reaction force vector is related to higher levels of sprint acceleration performance across a range of athletes. However, the effects of acute experimental alterations to the force vector orientation within athletes are unknown. Fifteen male team sports athletes completed maximal effort 10-m accelerations in three conditions following different verbal instructions intended to manipulate the force vector orientation. Ground reaction forces (GRFs) were collected from the step nearest 5-m and stance leg kinematics at touchdown were also analysed to understand specific kinematic features of touchdown technique which may influence the consequent force vector orientation. Magnitude-based inferences were used to compare findings between conditions. There was a likely more horizontally oriented ground reaction force vector and a likely lower peak vertical force in the control condition compared with the experimental conditions. 10-m sprint time was very likely quickest in the control condition which confirmed the importance of force vector orientation for acceleration performance on a within-athlete basis. The stance leg kinematics revealed that a more horizontally oriented force vector during stance was preceded at touchdown by a likely more dorsiflexed ankle, a likely more flexed knee, and a possibly or likely greater hip extension velocity.

Athletes have a higher risk of infection with Staphylococcus aureus than the general population. Most studies in athletes have included primarily male contact sports participants and have not assessed S. aureus carriage over time. We aimed to examine the epidemiology and risk factors of S. aureus carriage in a cohort of male and female collegiate athletes. We conducted a prospective cohort study of 377 varsity collegiate athletes from August 2008 to April 2010. A baseline questionnaire ascertained risk factors for colonization. Nasal and oropharyngeal swabs were obtained at enrollment and monthly thereafter to detect S. aureus colonization. The primary outcome was S. aureus colonization, both with methicillin-susceptible and methicillin-resistant S. aureus, as defined by bacterial culture and molecular confirmation. Secondary outcomes were time to colonization with S. aureus and carriage profile, defined as non-carrier, intermittent carrier, or persistent carrier. Overall, 224 contact sports and 153 non-contact sports athletes were enrolled. Contact sports athletes had a higher risk of carrying S. aureus over time: They had higher odds of being colonized with MRSA (OR 2.36; 95 % CI 1.13-4.93) and they tended to carry S. aureus for longer periods of time (intermittent carriage OR 3.60; 95 % CI 2.02-6.40; persistent carriage OR 2.39; 95 % CI 1.21-4.72). Athletes engaged in contact sports also acquired S. aureus more quickly (HR 1.61; 95 % CI 1.02-2.55). Staphylococcus aureus carriage was common in contact sports athletes. These findings suggest that efforts to prevent transmission of S. aureus among athletes should be focused on contact sports teams.

Competitiveness and the Process of Co-adaptation in Team Sport Performance

PubMed Central

Passos, Pedro; Araújo, Duarte; Davids, Keith

2016-01-01

An evolutionary psycho-biological perspective on competitiveness dynamics is presented, focusing on continuous behavioral co-adaptations to constraints that arise in performance environments. We suggest that an athlete’s behavioral dynamics are constrained by circumstances of competing for the availability of resources, which once obtained offer possibilities for performance success. This defines the influence of the athlete-environment relationship on competitiveness. Constraining factors in performance include proximity to target areas in team sports and the number of other competitors in a location. By pushing the athlete beyond existing limits, competitiveness enhances opportunities for co-adaptation, innovation and creativity, which can lead individuals toward different performance solutions to achieve the same performance goal. Underpinned by an ecological dynamics framework we examine whether competitiveness is a crucial feature to succeed in team sports. Our focus is on intra-team competitiveness, concerning the capacity of individuals within a team to become perceptually attuned to affordances in a given performance context which can increase their likelihood of success. This conceptualization implies a re-consideration of the concept of competitiveness, not as an inherited trait or entity to be acquired, but rather theorizing it as a functional performer-environment relationship that needs to be explored, developed, enhanced and maintained in team games training programs.

Actical ® actigraphy is commonly used to monitor athlete sleep. The proprietary software, called Actiware ® , processes data with three different sleep-wake thresholds (Low, Medium or High), but there is no standardisation regarding their use. The purpose of this study was to examine validity and bias of the sleep-wake thresholds for processing Actical ® sleep data in team sport athletes. Validation study comparing actigraph against accepted gold standard polysomnography (PSG). Sixty seven nights of sleep were recorded simultaneously with polysomnography and Actical ® devices. Individual night data was compared across five sleep measures for each sleep-wake threshold using Actiware ® software. Accuracy of each sleep-wake threshold compared with PSG was evaluated from mean bias with 95% confidence limits, Pearson moment-product correlation and associated standard error of estimate. The Medium threshold generated the smallest mean bias compared with polysomnography for total sleep time (8.5min), sleep efficiency (1.8%) and wake after sleep onset (-4.1min); whereas the Low threshold had the smallest bias (7.5min) for wake bouts. Bias in sleep onset latency was the same across thresholds (-9.5min). The standard error of the estimate was similar across all thresholds; total sleep time ∼25min, sleep efficiency ∼4.5%, wake after sleep onset ∼21min, and wake bouts ∼8 counts. Sleep parameters measured by the Actical ® device are greatly influenced by the sleep-wake threshold applied. In the present study the Medium threshold produced the smallest bias for most parameters compared with PSG. Given the magnitude of measurement variability, confidence limits should be employed when interpreting changes in sleep parameters. Copyright © 2017 Sports Medicine Australia. All rights reserved.

Emotional Intelligence, Motivational Climate and Levels of Anxiety in Athletes from Different Categories of Sports: Analysis through Structural Equations

(1) Background: Psychological factors can strongly affect the athletes’ performance. Therefore, currently the role of the sports psychologist is particularly relevant, being in charge of training the athlete’s psychological factors. This study aims at analysing the connections between motivational climate in sport, anxiety and emotional intelligence depending on the type of sport practised (individual/team) by means of a multigroup structural equations analysis. (2) 372 semi-professional Spanish athletes took part in this investigation, analysing motivational climate (PMCSQ-2), emotional intelligence (SSRI) and levels of anxiety (STAI). A model of multigroup structural equations was carried out which fitted accordingly (χ2 = 586.77; df = 6.37; p < 0.001; Comparative Fit Index (CFI) = 0.951; Normed Fit Index (NFI) = 0.938; Incremental Fit Index (IFI) = 0.947; Root Mean Square Error of Approximation (RMSEA) = 0.069). (3) Results: A negative and direct connection has been found between ego oriented climate and task oriented climate, which is stronger and more differentiated in team sports. The most influential indicator in ego oriented climate is intra-group rivalry, exerting greater influence in individual sports. For task-oriented climate the strongest indicator is having an important role in individual sports, while in team sports it is cooperative learning. Emotional intelligence dimensions correlate more strongly in team sports than in individual sports. In addition, there was a negative and indirect relation between task oriented climate and trait-anxiety in both categories of sports. (4) Conclusions: This study shows how the task-oriented motivational climate or certain levels of emotional intelligence can act preventively in the face of anxiety states in athletes. Therefore, the development of these psychological factors could prevent anxiety states and improve performance in athletes. PMID:29724008

Sports Specialization and Intensive Training in Young Athletes.

Sports specialization is becoming the norm in youth sports for a variety of reasons. When sports specialization occurs too early, detrimental effects may occur, both physically and psychologically. If the timing is correct and sports specialization is performed under the correct conditions, the athlete may be successful in reaching specific goals. Young athletes who train intensively, whether specialized or not, can also be at risk of adverse effects on the mind and body. The purpose of this clinical report is to assist pediatricians in counseling their young athlete patients and their parents regarding sports specialization and intensive training.

Abstract The main goal of this study was to present a review of current knowledge and modern trends in periodization of the training process in team sports. The research objectives were: an analysis of various aspects of periodization of the annual training cycle for elite athletes practicing team sport games, an attempt to determine both the examined and unexamined issues related with periodization of training as well as to indicate directions for further research, and finally, presentation of different training loads and competitions in micro-, meso- and macrocycles. The research consisted of the analysis and generalization of the bibliography, methods of monitoring training and competition loads of the Polish national U17 female soccer team in the seasons 2011/2012 and 2012/2013, as well as of the female basketball division one club in the season 2014/2015. Findings of the present study indicate resolved as well as unresolved aspects of annual training cycle periodization in team sport games and provide information on the types of training and competitive workload planning in micro-, meso- and macrocycles.

Limited research exists on the effect of a sports dietitian (SD) on athletes' dietary habits and nutrient periodization, which is the deliberate manipulation of macronutrient intake to match training goals. Further, the difference in dietary habits between men and women collegiate athletes has been understudied. A survey questionnaire examining dietary habits and practices was administered to athletes at two universities that employed a full time SD. Not all athletes used the SD as their primary source for nutritional guidance. The purposes were to examine the effect of a SD as a primary source of nutrition information, and the effect of gender on dietary habits in collegiate athletes. Three hundred eighty-three women ( n  = 240) and men ( n  = 143) student-athletes (mean ± SD: age = 19.7 ± 1.4 years) from 10 collegiate sports took a 15-min survey consisting of questions on dietary habits and practices. Topics queried included eating habits, breakfast habits, hydration habits, nutritional supplementation use, pre-workout nutrition, post-workout nutrition, nutrition during team trips, and nutrient timing. Data were sorted by the athlete's source of nutritional information (i.e., sport dietitian, other). Data analysis consisted of descriptive statistics and 2-way Pearson X 2 analyses ( p  ≤ 0.10). When a SD was indicated as the primary nutrition information source, athletes appeared to have a greater understanding of nutrient periodization (47.12 % vs. 32.85 %), were more likely to have school-provided boxed meals while on team trips (21.29 % vs. 6.77 %), and also less likely to consume fast food while on team trips (9.90 % vs. 19.55 %). Men athletes consumed fast food or restaurant meals more frequently, had higher weekly and more frequent alcohol intake during the competitive season. Women athletes were more likely to prepare meals, eat breakfast 7 days a week, and have school-provided boxed meals. Positive effects on dietary

Athletes enter injury rehabilitation with certain expectations about the recovery process, outcomes, and the professional providing treatment. Their expectations influence the effectiveness of the assistance received and affect the overall rehabilitation process. Expectations may vary depending on numerous factors such as sport experience, gender, sport type, and cultural background. Unfortunately, limited information is available on athletes' expectations about sport-injury rehabilitation. To examine possible differences in athletes' expectations about sport-injury rehabilitation based on their country of residence and type of sport (contact vs noncontact). Cross-sectional. Recreational, college, and professional athletes from the US, UK, and Finland were surveyed. Of the 1209 athletes ranging from 12 to 80 y of age (mean 23.46 ± 7.91), 529 US [80%], 253 UK [86%], and 199 Finnish [82%] athletes provided details of their geographical location and were included in the final analyses. The Expectations About Athletic Training (EAAT) questionnaire was used to determine athletes' expectations about personal commitment, facilitative conditions, and the expertise of the sports-medicine professional (SMP). A 3 × 2 MANCOVA revealed significant main effects for country (P = .0001, η p 2 = .055) and sport type (P = .0001, η p 2 = .023). Specifically, US athletes were found to have higher expectations of personal commitment and facilitative conditions than their UK and Finnish counterparts. Athletes participating in contact sports had higher expectations of facilitative conditions and the expertise of the SMP than did athletes participating in noncontact sports. SMPs, especially those in the US, should consider the sport and environment when providing services. In addition, SMPs need to highlight and demonstrate their expertise during the rehabilitation process, especially for those who compete in contact sports.

The rodeo athlete: sport science: part I.

Based on the tradition, history and lore of the American West, as well as the individualistic nature and lifestyle of the sport of rodeo, the rodeo athlete has achieved iconic status in sport, literature, art and entertainment. For over half a century, rodeo has become a staple of organized sport programmes in high schools, universities and international competitions. The origins of rodeo grew from ranch work dating back to the Spanish vaqueros in the 1700s. The sport was officially organized in 1929 and, by the 1930s, championships were determined and the sport of rodeo surpassed baseball and auto racing in spectator attendance. Since then, sponsorship has grown, resulting in extensive worldwide popularity through major media outlets. Despite growing popularity, few investigations exist regarding the scientific aspects of the sport. Rodeo competition is an activity that is basically intermittent in nature, with short periods of highly intense activity. When considering that experience and, thus, improvement in rodeo is achieved solely through constant and punishing practices involving actual and repetitive, human versus livestock competition, the practices closely imitate a sport-specific form of interval training. Studies, which address the anthropometric and performance characteristics of rodeo competitors, reveal that they are comparable to athletes in more traditional sports. The psychological constructs conducive to performance in rodeo have been varied and limited, with most research efforts focused on personality characteristics, sensation seeking and competitive anxiety. Nevertheless, when evaluated relative to higher levels of traditional sport performance, rodeo participants closely resemble their mainstream counterparts. Although efforts to quantify this non-traditional sport are still in the initial stages, information concerning what the optimal fitness level of rodeo athletes should be for maximal performance levels, in a basically anaerobic sport

Sports specialization is intense training in 1 sport while excluding others. Sports specialization in early to middle childhood has become increasingly common. While most experts agree that some degree of sports specialization is necessary to achieve elite levels, there is some debate as to whether such intense practice time must begin during early childhood and to the exclusion of other sports to maximize potential for success. There is a concern that sports specialization before adolescence may be deleterious to a young athlete. PubMed and OVID were searched for English-language articles from 1990 to 2011 discussing sports specialization, expert athletes, or elite versus novice athletes, including original research articles, consensus opinions, and position statements. For most sports, there is no evidence that intense training and specialization before puberty are necessary to achieve elite status. Risks of early sports specialization include higher rates of injury, increased psychological stress, and quitting sports at a young age. Sports specialization occurs along a continuum. Survey tools are being developed to identify where athletes fall along the spectrum of specialization. Some degree of sports specialization is necessary to develop elite-level skill development. However, for most sports, such intense training in a single sport to the exclusion of others should be delayed until late adolescence to optimize success while minimizing injury, psychological stress, and burnout.

The last few decades have seen substantial growth in the populations of competitive athletes and highly active people (CAHAP). Although vigorous physical exercise is an effective way to reduce the risk of cardiovascular (CV) disease, CAHAP remain susceptible to inherited and acquired CV disease, and may be most at risk for adverse CV outcomes during intense physical activity. Traditionally, multidisciplinary teams comprising athletic trainers, physical therapists, primary care sports medicine physicians, and orthopedic surgeons have provided clinical care for CAHAP. However, there is increasing recognition that a care team including qualified CV specialists optimizes care delivery for CAHAP. In recognition of the increasing demand for CV specialists competent in the care of CAHAP, the American College of Cardiology has recently established a Sports and Exercise Council. An important primary objective of this council is to define the essential skills necessary to practice effective sports cardiology. Copyright © 2017. Published by Elsevier Inc.

Proposed algorithm for the management of athletes with athletic pubalgia (sports hernia): a case series.

2008-12-01

A case series of 6 athletes with a suspected sports hernia. Groin pain in athletes is common, and 1 source of groin pain is athletic pubalgia, or a sports hernia. Description of this condition and its management is scarce in the physical therapy literature. The purpose of this case series is to describe a conservative approach to treating athletes with a likely sports hernia and to provide physical therapists with an algorithm for managing athletes with this dysfunction. Six collegiate athletes (age range, 19-22 years; 4 males, 2 females) with a physician diagnosis of groin pain secondary to possible/probable sports hernia were referred to physical therapy. A method of evaluation was constructed and a cluster of 5 key findings indicative of a sports hernia is presented. The athletes were managed according to a proposed algorithm and received physical therapy consisting of soft tissue and joint mobilization/manipulation, neuromuscular re-education, manual stretching, and therapeutic exercise. Three of the athletes received conservative intervention and were able to fully return to sport after a mean of 7.7 sessions of physical therapy. The other 3 athletes reached this outcome after surgical repair and a mean of 6.7 sessions of physical therapy. Conservative management including manual therapy appears to be a viable option in the management of athletes with a sports hernia. Follow-up randomized clinical trials should be performed to further investigate the effectiveness of conservative rehabilitation compared to a homogeneous group of patients undergoing surgical repair for this condition.

The effect of socioeconomic status (SES) on rates of sports specialization and injury among youth athletes has not been described previously. Young athletes from lower socioeconomic status will have lower rates of sports specialization and subsequently lower risk of overuse injuries. Cohort study. Level 3. Injured athletes aged 7 to 18 years were recruited from 2 hospital-based sports medicine clinics and compared with uninjured athletes presenting for sports physicals at primary care clinics between 2010 and 2013. Participants completed surveys on training patterns. Electronic medical records provided injury details as well as patient zip code, race, and health insurance type. SES was estimated from zip codes. The sample was divided into SES tertiles. Analysis of variance and multivariate regression were used for continuous variables, and multivariate logistic regression analyses were conducted to explore relationships between risk factors and injury. Of 1190 athletes surveyed, 1139 (96%) had satisfactory SES data. Compared with low-SES athletes, high-SES athletes reported more hours per week spent playing organized sports (11.2 ± 6.0 vs 10.0 ± 6.5; P = 0.02), trained more months per year in their main sport (9.7 ± 3.1 vs 7.6 ± 3.7; P < 0.01), were more often highly specialized (38.9% vs 16.6%; P < 0.01), and had increased participation in individual sports (64.8% vs 40.0%; P < 0.01). The proportion of athletes with a greater than 2:1 ratio of weekly hours in organized sports to free play increased with SES. Accounting for age and weekly organized sports hours, the odds of reporting a serious overuse injury increased with SES (odds ratio, 1.5; P < 0.01). High-SES athletes reported more serious overuse injuries than low-SES athletes, potentially due to higher rates of sports specialization, more hours per week playing organized sports, higher ratio of weekly hours in organized sports to free play, and greater participation in individual sports. As SES increases

Olympic athletes are vulnerable to traumatic, environmental and infectious skin manifestations. Although dermatological complaints are frequent among Olympians, there is a scarcity of literature that reviews sports-related dermatoses among Olympic athletes. A comprehensive review of PREMEDLINE and MEDLINE searches of all available literature through to January 2011 was conducted, focusing on sports-related dermatological presentations as well as the key words 'Olympic athletes' and 'skin diseases'. Common skin conditions can be harmful and even prohibitive for competition. Common aetiologies of dermatological conditions related to sports include: skin infections with dermatophytes such as tinea pedis and tinea corporis, bacteria such as pitted keratolysis, and folliculitis and viruses such as herpes gladiatorum. Frictional dermatoses occur commonly and include athlete's nodules, jogger's itch, frictional blisters, callosities and talon noir. Trauma can cause haematomas such as auricular haematomas. Due to long training hours in the sun, many endurance athletes experience high levels of UV radiation and a higher risk for both melanoma and non-melanoma skin cancer. Pre-existing dermatoses can also be aggravated with practice and competition; in particular, atopic eczema and physical urticarias. Infrequent dermatoses are susceptible to misdiagnosis, delay in treatment and needless biopsies. This review highlights the diagnosis and management of sports-related dermatoses by the following general categories of Olympic sport: endurance, resistance, team sport, and performing arts.

Athletic identity and psychiatric symptoms following retirement from varsity sports.

Despite evidence identifying adjustment difficulties among retiring athletes, research investigating factors that contribute to post-retirement complications is limited. Athletic identity may be an important determinant of adverse adaptation to sport retirement. The purpose of this study was to address the influence of athletic identity on post-retirement depression and anxiety symptoms among varsity athletes. An anonymous, online survey regarding athletic identity and psychiatric symptoms was completed by 72 self-identified varsity athletes during their final season of competition and 3 months after retiring from sport. After controlling for the effects of pre-retirement anxiety symptoms, endorsement of an athletic identity significantly predicted anxiety symptoms in the post-retirement period. A similar, but non-significant, pattern was observed for depressive symptoms. The findings of this study suggest that athletes' degree of athletic identity may be a risk factor for the emergence of psychiatric distress in the months following their retirement from sport. Identity-focused screening or intervention during athletes' sport careers could potentially mitigate some of the psychological difficulties associated with sport retirement.

The present study examines the sport motivation and the goal orientations in the competitive and non-competitive structure of rhythmic gymnastics. Participation of individuals in one or the other structure of the sport differs in line with the goals they want to achieve and possibly also with respect to the factors that impulse them to take part in one or the other. The purpose of this study is to examine how individuals who participate in different structures of the sport of rhythmic gymnastics differentiate with regard to the type of motivation (intrinsic, extrinsic, amotivation) and goal orientations. The study involved 98 young female rhythmic gymnastics athletes (aged 14 years and up), out of which 40 were athletes of competitive clubs or members of national teams, and 58 were athletes of non-competitive clubs. For the evaluation of motivation and goal orientations the following tools were used: the Sport Motivation Scale (SMS) and the Task and Ego Orientation in Sport Questionnaire (TEOSQ). Descriptive and inductive statistical data analysis was conducted. The results showed that the athletes of the non-competitive structure presented higher levels of introjected regulation (extrinsic motivation), amotivation and lower levels of ego orientation (P<0.05). Rhythmic gymnastics athletes' (regardless of the structure of the sport) presented high level in task orientation while the high levels of task orientation is positively associated with high levels of intrinsic motivation regardless of the levels of ego orientation. The intrinsic motivation of athletes participating in rhythmic gymnastics runs at high levels. The amotivation of rhythmic gymnastics athletes' is a phenomenon which is also presented in the the non-competitive sport structure. It is important that the two different structures of sports be determined with accurate criteria.

Background Sports injury and illness surveillance is the first step in injury and illness prevention, and is important for the protection of both athlete health and performance in major competitions. Aim To identify the prevalence, severity nature and causes of athlete injuries and illnesses in the Great Britain Olympic Team (TeamGB) during the Sochi 2014 Winter Olympic Games. Methods The observational prospective cohort study followed the Great Britain Injury/Illness Performance Project surveillance methodology and obtained information on injuries and illnesses that occurred during the Games between 30 January and 23 February 2014 in TeamGB athletes (n=56). Results Among the 56 TeamGB athletes, there were 27 injuries and 11 illnesses during the Olympic Games period. This equated to 39% sustaining at least one injury and 18% at least one illness, with an incidence of 48.2 injuries and 19.6 illnesses per 100 athletes, respectively. Of all injuries and illnesses, 9% and 7%, respectively, resulted in time loss. The risk of sustaining an injury was highest for freestyle skiing, skeleton and snowboarding; and lowest for curling, biathlon and Alpine skiing (with no reported injuries); with the lower limb being the most commonly injured location. Respiratory system illnesses were most frequently reported overall, and older female athletes were the ones most affected by illness. Conclusions The risk of injury was double the risk of illness for TeamGB athletes. Overall, the rate of time-loss issues was low. Methodological considerations are important when interpreting data, and prevention strategies should focus on those issues causing the greatest risk, in terms of prevalence and severity, to athlete health and performance.

2018-05-01

Sports periodization has traditionally focused on the exercise aspect of athletic preparation, while neglecting the integration of other elements that can impact an athlete's readiness for peak competition performances. Integrated periodization allows the coordinated inclusion of multiple training components best suited for a given training phase into an athlete's program. The aim of this article is to review the available evidence underpinning integrated periodization, focusing on exercise training, recovery, nutrition, psychological skills, and skill acquisition as key factors by which athletic preparation can be periodized. The periodization of heat and altitude adaptation, body composition, and physical therapy is also considered. Despite recent criticism, various methods of exercise training periodization can contribute to performance enhancement in a variety of elite individual and team sports, such as soccer. In the latter, both physical and strategic periodization are useful tools for managing the heavy travel schedule, fatigue, and injuries that occur throughout a competitive season. Recovery interventions should be periodized (ie, withheld or emphasized) to influence acute and chronic training adaptation and performance. Nutrient intake and timing in relation to exercise and as part of the periodization of an athlete's training and competition calendar can also promote physiological adaptations and performance capacity. Psychological skills are a central component of athletic performance, and their periodization should cater to each athlete's individual needs and the needs of the team. Skill acquisition can also be integrated into an athlete's periodized training program to make a significant contribution to competition performance.

To describe the socioeconomic status, measured by household income and educational attainment, of parents with children participating on youth club sport teams. Cross-sectional survey. Local sport events. 949 parents (571 female) of youth athletes between 10 and 18 years old were recruited at club team events and practices to complete an anonymous questionnaire. SES variables included total household income (THI) and educational attainment. Sport specialization was classified as low, moderate, or high using a previously utilized 3-point specialization scale. Chi-square tests were used to compare frequencies SES categories with child specialization. Parents reported spending a median of 1500 [500-3000] USD per year on their children's club sports activities. Most parents reported a THI greater than 100,000 USD per year and a bachelor's degree or higher level of education. Parents in the higher THI categories were more likely to have a child that is highly specialized in one sport. The current youth sports system in the United States, which emphasizes year-round participation on club teams, may be limiting the participation of families without the resources to participate in this system.

Sports injury and illness surveillance is the first step in injury and illness prevention, and is important for the protection of both athlete health and performance in major competitions. To identify the prevalence, severity nature and causes of athlete injuries and illnesses in the Great Britain Olympic Team (TeamGB) during the Sochi 2014 Winter Olympic Games. The observational prospective cohort study followed the Great Britain Injury/Illness Performance Project surveillance methodology and obtained information on injuries and illnesses that occurred during the Games between 30 January and 23 February 2014 in TeamGB athletes (n=56). Among the 56 TeamGB athletes, there were 27 injuries and 11 illnesses during the Olympic Games period. This equated to 39% sustaining at least one injury and 18% at least one illness, with an incidence of 48.2 injuries and 19.6 illnesses per 100 athletes, respectively. Of all injuries and illnesses, 9% and 7%, respectively, resulted in time loss. The risk of sustaining an injury was highest for freestyle skiing, skeleton and snowboarding; and lowest for curling, biathlon and Alpine skiing (with no reported injuries); with the lower limb being the most commonly injured location. Respiratory system illnesses were most frequently reported overall, and older female athletes were the ones most affected by illness. The risk of injury was double the risk of illness for TeamGB athletes. Overall, the rate of time-loss issues was low. Methodological considerations are important when interpreting data, and prevention strategies should focus on those issues causing the greatest risk, in terms of prevalence and severity, to athlete health and performance.

It is the position of Sports Dietitians Australia (SDA) that adolescent athletes have unique nutritional requirements as a consequence of undertaking daily training and competition in addition to the demands of growth and development. As such, SDA established an expert multidisciplinary panel to undertake an independent review of the relevant scientific evidence and consulted with its professional members to develop sports nutrition recommendations for active and competitive adolescent athletes. The position of SDA is that dietary education and recommendations for these adolescent athletes should reinforce eating for long term health. More specifically, the adolescent athlete should be encouraged to moderate eating patterns to reflect daily exercise demands and provide a regular spread of high quality carbohydrate and protein sources over the day, especially in the period immediately after training. SDA recommends that consideration also be given to the dietary calcium, Vitamin D and iron intake of adolescent athletes due to the elevated risk of deficiency of these nutrients. To maintain optimal hydration, adolescent athletes should have access to fluids that are clean, cool and supplied in sufficient quantities before, during and after participation in sport. Finally, it is the position of SDA that nutrient needs should be met by core foods rather than supplements, as the recommendation of dietary supplements to developing athletes over-emphasizes their ability to manipulate performance in comparison with other training and dietary strategies.

Gambling on college and professional sports and the influence of attending colleges with differing levels of "sports interest" were examined among athletes, sports fans, and other students (N = 10,559) at 119 colleges in the United States using multilevel statistical analysis. Athletes and fans reported more sports gambling compared to other students, with no differences between athletes and fans. Male students were more likely to gamble than female students, but gender did not moderate the relationship between athletic participation and sports gambling. Students attending schools with a greater "sports interest" were more likely to gamble on college sports after adjusting for individual characteristics. Athletes, sports fans, and students attending schools with high "sports interest" are appropriate targets for prevention efforts.

Anecdotal and qualitative evidence has suggested that some clinicians face pressure from coaches and other personnel in the athletic environment to prematurely return athletes to participation after a concussion. This type of pressure potentially can result in compromised patient care. To quantify the extent to which clinicians in the collegiate sports medicine environment experience pressure when caring for concussed athletes and whether this pressure varies by the supervisory structure of the institution's sports medicine department, the clinician's sex, and other factors. Cross-sectional study. Web-based survey of National College Athletic Association member institutions. A total of 789 athletic trainers and 111 team physicians from 530 institutions. We asked participants whether they had experienced pressure from 3 stakeholder populations (other clinicians, coaches, athletes) to prematurely return athletes to participation after a concussion. Modifying variables that we assessed were the position (athletic trainer, physician) and sex of the clinicians, the supervisory structure of their institutions' sports medicine departments, and the division of competition in which their institutions participate. We observed that 64.4% (n = 580) of responding clinicians reported having experienced pressure from athletes to prematurely clear them to return to participation after a concussion, and 53.7% (n = 483) reported having experienced this pressure from coaches. Only 6.6% (n = 59) reported having experienced pressure from other clinicians to prematurely clear an athlete to return to participation after a concussion. Clinicians reported greater pressure from coaches when their departments were under the supervisory purview of the athletic department rather than a medical institution. Female clinicians reported greater pressure from coaches than male clinicians did. Most clinicians reported experiencing pressure to prematurely return athletes to participation after a

To study the relationship between sporting activity and alcohol, cigarette and cannabis use among adolescents and young adults, by focusing on elite student athletes (ESAs). Cross-sectional survey (Spring 2002), in a sample of 460 ESAs (ages 16-24 years) recruited at 40 public centres gathering the young sporting elite from 30 different sports in South-Eastern France, comparison with samples of the general population of adolescents in South-Eastern France. Respondents were asked confidentially by a self-administered questionnaire about their use of licit and illicit drugs, their sporting activity and other aspects of their life-style. Prevalences of cigarette, alcohol and cannabis use were markedly lower for ESAs than for other adolescents (generally twice or three times as low). Among ESAs, when compared with the practice of an individual sport, the practice of a team sport was correlated positively with alcohol use (OR = 2.7 for girls, OR = 1.8 for boys), and the practice of a sliding sport was correlated positively with cannabis use (for girls: OR = 2.3) and with alcohol use (for boys: 4.3). Girls who entered competition at international level were more prone to smoke cigarettes and cannabis (OR = 6.1 and 2.4, respectively). As a whole, practising sports as an elite student-athlete can be considered as correlated negatively with cigarette, alcohol and cannabis use. Nevertheless, this relationship depends on the kind of sport practised as well as the level of competition, and further research is needed to understand specific elite athletes' motives for use.

The sporting body: body image and eating disorder symptomatology among female athletes from leanness focused and nonleanness focused sports.

PubMed

Kong, Peiling; Harris, Lynne M

2015-01-01

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.

Gender, level of participation, and type of sport: differences in achievement goal orientation and attributional style.

PubMed

Hanrahan, Stephanie J; Cerin, Ester

2009-07-01

Findings regarding gender differences in achievement goal orientations and attributional style have been somewhat inconsistent. One possible explanation for varied findings is that potentially confounding variables such as level of participation and type of sport have not been considered. Athletes (108 males and 164 females) from team and individual sports, competing at recreational and competitive levels, completed the Task and Ego Orientation in Sport Questionnaire, the Sport Attributional Style Scale, and a demographic questionnaire. Athletes competing in individual sports had a higher ego orientation than those from team sports, and females scored higher in task orientation than males. Individual sport athletes made more internal, stable, and global, and less externally controllable attributions for positive events, and more internal attributions for negative events than team sport athletes. Competitive female athletes made less global attributions for positive events than did recreational female athletes. This difference was not observed in male athletes. Competitive individual, but not team, athletes made less global attributions than recreational individual athletes. The significant interactions regarding globality suggest that the tradition in sport psychology attribution research to focus solely on internality, stability, and controllability may be inadequate. From an applied perspective, sport psychologists and coaches may find it beneficial to target individual sport athletes and males for interventions designed to enhance task orientation. Similarly, team sport athletes may be appropriate as a focus for attribution retraining programs.

2014-01-01

In this study, we explored the multifaceted concept of perceived mental and physical effort in team sport contexts where athletes must invest individual and shared efforts to reach a common goal. Semi-structured interviews were conducted with a convenience sample of 15 Catalan professional coaches (3 women and 12 men, 3 each from the following sports: volleyball, basketball, handball, soccer, and water polo) to gain their views of three perceived effort-related dimensions: physical, psychological, and tactical. From a theoretical thematic analysis, it was found that the perception of effort is closely related to how effort is distributed within the team. Moreover, coaches viewed physical effort in relation to the frequency and intensity of the players' involvement in the game. They identified psychological effort in situations where players pay attention to proper cues, and manage emotions under difficult circumstances. Tactical effort addressed the decision-making process of players and how they fulfilled their roles while taking into account the actions of their teammates and opponents. Based on these findings, a model of perceived distributed effort was developed, which delineates the elements that compose each of the aforementioned dimensions. Implications of perceived distributed effort in team coordination and shared mental models are discussed.

Use of Global positioning system (GPS) technology in team sport permits measurement of player position, velocity, and movement patterns. GPS provides scope for better understanding of the specific and positional physiological demands of team sport and can be used to design training programs that adequately prepare athletes for competition with the aim of optimizing on-field performance. The objective of this study was to conduct a systematic review of the depth and scope of reported GPS and microtechnology measures used within individual sports in order to present the contemporary and emerging themes of GPS application within team sports. A systematic review of the application of GPS technology in team sports was conducted. We systematically searched electronic databases from earliest record to June 2012. Permutations of key words included GPS; male and female; age 12-50 years; able-bodied; and recreational to elite competitive team sports. The 35 manuscripts meeting the eligibility criteria included 1,276 participants (age 11.2-31.5 years; 95 % males; 53.8 % elite adult athletes). The majority of manuscripts reported on GPS use in various football codes: Australian football league (AFL; n = 8), soccer (n = 7), rugby union (n = 6), and rugby league (n = 6), with limited representation in other team sports: cricket (n = 3), hockey (n = 3), lacrosse (n = 1), and netball (n = 1). Of the included manuscripts, 34 (97 %) detailed work rate patterns such as distance, relative distance, speed, and accelerations, with only five (14.3 %) reporting on impact variables. Activity profiles characterizing positional play and competitive levels were also described. Work rate patterns were typically categorized into six speed zones, ranging from 0 to 36.0 km·h⁻¹, with descriptors ranging from walking to sprinting used to identify the type of activity mainly performed in each zone. With the exception of cricket, no standardized speed zones or definitions were observed within or

Current trends among young athletes towards earlier specialization age and year-round training on multiple teams has raised concern for increased injury risk. Our previous analyses showed higher risk for injury in highly specialized young athletes. The goal of this research was to determine whether sports specialization and injury patterns vary by sports type. In this clinical case-control study, injured athletes (aged 7-18 years) were recruited from sports medicine clinics and compared to similarly aged uninjured athletes recruited from primary care clinics. Participants completed a survey reporting age, gender, sport type, specialization patterns, and details regarding sports-related injuries in the previous 6 months. Clinical diagnoses were collected from patients' medical records. Injuries were classified as acute, overuse, or serious overuse. Of 1,190 athletes enrolled, 26% (313) were single-sport specialized (reported participation in one sport and trained >8 months/year). Sports with the highest proportion of single-sport specialized athletes were tennis (46.7%), gymnastics (30.1%), and dance (26.3%). Single-sport specialized athletes in individual sports started specializing at a younger age (11.2 ± 2.4 vs. 12.0 ± 2.7, p = 0.05) and reported higher training volumes (11.8 vs. 10.3 h/week, p = 0.04) than those in team sports. Sports with the youngest specialization age were gymnastics (8.9 ± 1.7), dance (10.8 ± 3.0), and soccer (10.9 ± 2.4). Single-sport specialized athletes in individual sports accounted for a higher proportion of overuse injuries (44.3% vs 32.2%, OR = 1.67, p = 0.037) and serious overuse injuries (23.4% vs 11.6%, OR = 2.38, p = 0.011), but a lower proportion of acute injuries (28.8% vs 13.8%, OR = 0.37, p = 0.001) compared to single-sport specialized athletes involved in team sports. Athletes in individual sports may be more likely to specialize in a single sport than team sport athletes. Single-sport

2018-05-02

To develop and implement a prospective varsity athlete surveillance system to identify injury and illness trends in a multisport varsity-level university setting. Longitudinal prospective surveillance study. Varsity-level sport program at the University of Guelph, Guelph, ON, Canada. Athletic therapists (ATs) (n = 35) from 17 varsity sports provided injury and illness information on 624 varsity-level athletes (381 men and 243 women) during the 2016/2017 competitive season. Team ATs reported athlete health complaints weekly. Athletes reported additional details on the injury or illness that was reported. The outcome measurements included when the injury or illness occurred, anatomical location, diagnosis, cause, perceived severity, treatment, estimated athlete exposure (AE) to training and competition, and time loss from sport. Measures were recorded from the teams' first competition through to end their season and/or playoffs. Twenty-nine of 30 varsity sports teams participated in this injury and illness surveillance protocol. The compliance of team ATs and varsity athletes was 89% (men: 94%, women: 82%). The overall injury and illness rates were 5.5 injuries and 1.7 illnesses per 1000 AEs, respectively. Men's injury rates were greater than women's, and injury rates of contact sports were greater than noncontact sports. The utilization of a prospective injury and illness surveillance protocol in the Canadian University sport system is feasible with good athlete, AT, and coach acceptance. The surveillance data should inform future injury and illness prevention strategies.

2004-03-01

Although investigations have consistently demonstrated the effectiveness of sport psychology interventions, these methods have been underutilized by athletes. In this study, 124 athletes completed the athletes' Attitudes Toward Seeking Sport Psychology Consultation Questionnaire (ATSSPCQ) and were subsequently randomly assigned to receive one of the two semistructured interview formats. One interview focused on discussing the athlete's experiences in sports, and the other focused on delineating sport psychology and its potential benefits to the athlete. Upon being interviewed, athletes were readministered the ATSSPCQ. Discussing sport psychology and its personal benefits was more effective in enhancing athletes' perception of need for sport psychology than discussing sport experiences. However, neither interview format enhanced athletes' perceptions of openness to discuss personal issues with a sport psychology consultant and tolerance of stigma associated with sport psychology consultation. Indeed, participants who received the discussion of sports intervention reported a significant decrease in personal openness to discuss personal issues relevant to sports psychology from pre- to postintervention. Intervention effects were similar for male and female athletes. Study implications and future directions are discussed in light of these results.

The purpose of this study was to assess the nutrition knowledge and the factors determining this knowledge in Iranian college basketball and football athletes. By highlighting gaps in nutrition knowledge of these athletes, sport nutrition professionals may begin to address these gaps by educating athletes with a view toward minimizing injury and enhancing sport performance. Sixty-six basketball and 141 football players (response rate 78.4%) from 4 medical and 8 nonmedical universities in Tehran agreed to participate in this cross-sectional study. A 2-part questionnaire was used; the first part comprised questions identifying demographic information, and the second part comprised a previously well-validated questionnaire on sport nutrition knowledge. The overall knowledge score was 33.2% (+/- 12.3%). Men scored 28.2% (+/- 12.7%), and women, 38.7% (+/- 14.2%). In both genders, the highest score was obtained for the nutrients subcategory, and the supplements subcategory was the most poorly answered. When compared with their peers, a significantly higher score was obtained by women (p < .001), athletes at medical universities (p < .001), and those obtaining nutrition information from reputable sources (p = .03). The coach was cited by 89.4% of athletes as their main source of nutrition information. This study showed that the sport nutrition knowledge of these athletes is inadequate. Considering that this substandard level of knowledge may contribute to poor dietary behaviors, these athletes would benefit from nutrition-related training and education.

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.

Sport-related achievement motivation and alcohol outcomes: an athlete-specific risk factor among intercollegiate athletes.

2013-12-01

Intercollegiate athletes report greater alcohol consumption and more alcohol-related problems than their non-athlete peers. Although college athletes share many of the same problems faced by non-athletes, there are some consequences that are unique to athletes. Studies have demonstrated that alcohol negatively affects athletic performance including increased dehydration, impeded muscle recovery, and increased risk for injury. Beyond risk factors for alcohol misuse that may affect college students in general, research has begun to examine risk factors that are unique to collegiate athletes. For example, research has found that off-season status, the leadership role, and athlete-specific drinking motives are associated with increased alcohol use. Given these findings, it is possible that other athlete-specific variables influence alcohol misuse. One such variable may be sport achievement orientation. The purpose of the current study was to examine the relationship between sport achievement orientation and alcohol outcomes. Given previous research regarding seasonal status and gender, these variables were examined as moderators. Varsity athletes (n=263) completed the Sport Orientation Questionnaire, which assesses sport-related achievement orientation on three scales (Competitiveness, Win Orientation, and Goal Orientation). In addition, participants completed measures of alcohol use and alcohol-related problems. Results indicated that Competitiveness, Win Orientation, and Goal Orientation were all significantly associated with alcohol use, but not alcohol-related problems. Moreover, these relationships were moderated by seasonal status and gender. These interactions, clinical implications, and limitations are discussed. © 2013.

Beyond risk factors for alcohol misuse that may affect college students in general, research has begun to examine risk factors that are unique to collegiate athletes. For example, research has found that off-season status, the leadership role, and athlete-specific drinking motives are associated with increased alcohol use. Given these findings, it is possible that other athlete-specific variables influence alcohol misuse. One such variable may be sport achievement orientation. The purpose of the current study was to examine the relationship between sport achievement orientation and alcohol outcomes. Given previous research regarding seasonal status and gender, these variables were examined as moderators. Varsity athletes (n = 263) completed the Sport Orientation Questionnaire, which assesses sport-related achievement orientation on three scales (Competitiveness, Win Orientation, and Goal Orientation). In addition, participants completed measures of alcohol use and alcohol-related problems. Results indicated that Competitiveness, Win Orientation, and Goal Orientation were all significantly associated with alcohol use, but not alcohol-related problems. Moreover, these relationships were moderated by seasonal status and gender. These interactions, clinical implications, and limitations are discussed. PMID:24064192

Sports hernia/athletic pubalgia: evaluation and management.

PubMed

Larson, Christopher M

2014-03-01

Sports hernia/athletic pubalgia has received increasing attention as a source of disability and time lost from athletics. Studies are limited, however, lacking consistent objective criteria for making the diagnosis and assessing outcomes. PubMed database through January 2013 and hand searches of the reference lists of pertinent articles. Review article. Level 5. Nonsurgical outcomes have not been well reported. Various surgical approaches have return-to-athletic activity rates of >80% regardless of the approach. The variety of procedures and lack of outcomes measures in these studies make it difficult to compare one surgical approach to another. There is increasing evidence that there is an association between range of motion-limiting hip disorders (femoroacetabular impingement) and sports hernia/athletic pubalgia in a subset of athletes. This has added increased complexity to the decision-making process regarding treatment. An association between femoroacetabular impingement and athletic pubalgia has been recognized, with better outcomes reported when both are managed concurrently or in a staged manner.

Nutrition is an important part of sport performance for young athletes, in addition to allowing for optimal growth and development. Macronutrients, micronutrients and fluids in the proper amounts are essential to provide energy for growth and activity. To optimize performance, young athletes need to learn what, when and how to eat and drink before, during and after activity. PMID:24421690

The risks of sports participation for implantable cardioverter-defibrillator (ICD) patients are unknown. Athletes with ICDs (age, 10-60 years) participating in organized (n=328) or high-risk (n=44) sports were recruited. Sports-related and clinical data were obtained by phone interview and medical records. Follow-up occurred every 6 months. ICD shock data and clinical outcomes were adjudicated by 2 electrophysiologists. Median age was 33 years (89 subjects <20 years of age); 33% were female. Sixty were competitive athletes (varsity/junior varsity/traveling team). A pre-ICD history of ventricular arrhythmia was present in 42%. Running, basketball, and soccer were the most common sports. Over a median 31-month (interquartile range, 21-46 months) follow-up, there were no occurrences of either primary end point-death or resuscitated arrest or arrhythmia- or shock-related injury-during sports. There were 49 shocks in 37 participants (10% of study population) during competition/practice, 39 shocks in 29 participants (8%) during other physical activity, and 33 shocks in 24 participants (6%) at rest. In 8 ventricular arrhythmia episodes (device defined), multiple shocks were received: 1 at rest, 4 during competition/practice, and 3 during other physical activity. Ultimately, the ICD terminated all episodes. Freedom from lead malfunction was 97% at 5 years (from implantation) and 90% at 10 years. Many athletes with ICDs can engage in vigorous and competitive sports without physical injury or failure to terminate the arrhythmia despite the occurrence of both inappropriate and appropriate shocks. These data provide a basis for more informed physician and patient decision making in terms of sports participation for athletes with ICDs.

To determine the extent to which sports medicine physicians encounter and discuss psychological issues among athletes they treat and to evaluate physicians' perceptions of the availability and efficacy of sport psychologists and other mental health resources. Cross-sectional study. A survey was sent via e-mail to all physician members of 4 prominent sports medicine professional associations: the American Orthopaedic Society for Sports Medicine, American College of Sports Medicine, American Medical Society for Sports Medicine, and American Osteopathic Academy of Sports Medicine. The extent to which respondents discuss psychological issues with athletes varied by subspecialty and by specific issues assessed. Fears about reinjury, fears related to surgery, and lack of patience with recovery/rehabilitation were the 3 most common injury-related topics discussed with patient-athletes. The 3 most common non-injury-related topics discussed were stress/pressure, anxiety, and burnout. Family practitioners were more likely to discuss injury-related psychological issues than were orthopaedic surgeons. Orthopaedic surgeons reported the lowest frequencies of discussing non-injury-related psychological issues. Only 19% of all respondents indicated there were adequate numbers of sport psychologists and other mental health professionals in their geographical area to treat the needs of athletes. Three quarters of respondents reported they rarely or never referred athletes to sport psychologists for injury-related issues, and two thirds indicated they rarely or never referred athletes to sport psychologists for non-injury-related problems. Respondents rated sport psychologists and athletic trainers/physical therapists to be moderately effective in working with athletes regarding psychological problems. Sports medicine physicians frequently encounter psychological issues with patient-athletes. There is a need for tools to facilitate assessment of these problems as well as greater

Modelling Movement Energetics Using Global Positioning System Devices in Contact Team Sports: Limitations and Solutions.

PubMed

Gray, Adrian J; Shorter, Kathleen; Cummins, Cloe; Murphy, Aron; Waldron, Mark

2018-06-01

Quantifying the training and competition loads of players in contact team sports can be performed in a variety of ways, including kinematic, perceptual, heart rate or biochemical monitoring methods. Whilst these approaches provide data relevant for team sports practitioners and athletes, their application to a contact team sport setting can sometimes be challenging or illogical. Furthermore, these methods can generate large fragmented datasets, do not provide a single global measure of training load and cannot adequately quantify all key elements of performance in contact team sports. A previous attempt to address these limitations via the estimation of metabolic energy demand (global energy measurement) has been criticised for its inability to fully quantify the energetic costs of team sports, particularly during collisions. This is despite the seemingly unintentional misapplication of the model's principles to settings outside of its intended use. There are other hindrances to the application of such models, which are discussed herein, such as the data-handling procedures of Global Position System manufacturers and the unrealistic expectations of end users. Nevertheless, we propose an alternative energetic approach, based on Global Positioning System-derived data, to improve the assessment of mechanical load in contact team sports. We present a framework for the estimation of mechanical work performed during locomotor and contact events with the capacity to globally quantify the work done during training and matches.

Tendon adaptation due to mechanical loading is controversially discussed. However, data concerning the development of tendon thickness in adolescent athletes is sparse. The purpose of this study was to examine possible differences in Achilles (AT) and patellar tendon (PT) thickness in adolescent athletes while considering age, gender and sport-specific loading. In 500 adolescent competitive athletes of 16 different sports and 40 recreational controls both ATs and PTs were sonographically measured. Subjects were divided into 2 age groups (< 13; ≥ 13 years) and 6 sport type categories (ball, combat, and water sports, combined disciplines, cycling, controls). In addition, 3 risk groups (low, moderate, high) were created according to the athlete's risk of developing tendinopathy. AT and PT thickness did not significantly differ between age groups (AT/PT:<13: 5.4±0.7 mm/3.6±0.5 mm;≥13: 5.3±0.7 mm/3.6±0.5 mm). In both age groups males presented higher tendon thickness than females (p<0.001). AT thickness was highest in ball sports/cyclists and lowest in controls (p≤0.002). PT thickness was greatest in water sports and lowest in controls (p=0.02). High risk athletes presented slightly higher AT thickness compared to the low risk group (p=0.03). Increased AT and PT thickness in certain sport types compared to controls supports the hypothesis of structural tendon adaptation due to sport-specific loading. © Georg Thieme Verlag KG Stuttgart · New York.

MEDICAL SPORTS INJURIES IN THE YOUTH ATHLETE: EMERGENCY MANAGEMENT

PubMed Central

Molony Jr, Joseph T.

2012-01-01

As the number of youth sports participants continues to rise over the past decade, so too have sports related injuries and emergency department visits. With low levels of oversight and regulation observed in youth sports, the responsibility for safety education of coaches, parents, law makers, organizations and institutions falls largely on the sports medicine practitioner. The highly publicized catastrophic events of concussion, sudden cardiac death, and heat related illness have moved these topics to the forefront of sports medicine discussions. Updated guidelines for concussion in youth athletes call for a more conservative approach to management in both the acute and return to sport phases. Athletes younger than eighteen suspected of having a concussion are no longer allowed to return to play on the same day. Reducing the risk of sudden cardiac death in the young athlete is a multi‐factorial process encompassing pre‐participation screenings, proper use of safety equipment, proper rules and regulations, and immediate access to Automated External Defibrillators (AED) as corner stones. Susceptibility to heat related illness for youth athletes is no longer viewed as rooted in physiologic variations from adults, but instead, as the result of various situations and conditions in which participation takes place. Hydration before, during and after strenuous exercise in a high heat stress environment is of significant importance. Knowledge of identification, management and risk reduction in emergency medical conditions of the young athlete positions the sports physical therapist as an effective provider, advocate and resource for safety in youth sports participation. This manuscript provides the basis for management of 3 major youth emergency sports medicine conditions. PMID:22530197

To describe the attitudes of members of the American Medical Society for Sports Medicine (AMSSM) toward the new National Collegiate Athletic Association (NCAA) policy to require all Division I student athletes be screened for sickle cell trait (SCT), have prior evidence of testing, or sign a waiver. Cross-sectional survey of members of the AMSSM electronic mailing list was conducted. Descriptive, McNemar, and χ2 statistics were performed. Internet survey. Of the 1765 AMSSM e-mail list members, 370 returned partial or completed surveys. Dependent variables included familiarity with the NCAA policy, support of universal or targeted screening programs, preferences regarding screening methodologies, and athletic restrictions or modifications for student athletes identified with SCT. Respondents' gender, race/ethnicity, and involvement as an NCAA team physician were independent variables. Of the respondents, 76% were men, 85% were whites, and 53% served as NCAA Division I team physicians. Ninety percent were aware of the policy. There was greater support for targeted (76%, 267 of 353) compared with universal (39%, 137 of 353; P < 0.01) screening, with targeting based on race/ethnicity and sport. Respondents supported targeted screening of varsity and freshman athletes in all NCAA divisions, but most (88%) also supported waivers. Respondents favored using existing medical records (73%) or Sickledex screening (71%) methodologies despite concerns about inaccuracies (16% for each methodology). Most respondents agreed that there is discrimination in athletic participation and obtaining insurance. There is lack of consensus within the AMSSM regarding the current NCAA SCT screening policy. Implementation must take into consideration potential discrimination.

The purpose of this study was to examine the relationship between coaching competency and team conflict, at individual and team levels, over the season. The participants were professional female and male soccer players, who participated in the First and Second Division. A longitudinal study was performed. At Time 1, the sample of participants consisted of 581 soccer players aged between 15 and 39 years. At Time 2, 549 players were recruited from the original sample aged between 15 and 37 years. Finally, at Time 3, the sample comprised 576 players aged between 15 and 37 years. All participants completed a multi-section questionnaire assessing coaching competency (motivation, game strategy, technique competency, and character-building competency) and team conflict (task conflict and relationship conflict). Results showed that both task and relationship conflict increased significantly over time. Multilevel modelling analysis showed that game strategy and character-building competencies negatively predicted both task and relationship conflicts at the individual level, whereas motivation competency was also added as a significant predictor of task conflict at the team level. Moreover, technique competency positively predicted task conflict at the team level. The current study suggests the importance of coaching competency in group dynamics in sport.

To document the distribution of sociodemographic markers (race and relative access to wealth) in athletes participating at the summer and Winter Olympic Games (OGs). Cross-sectional descriptive epidemiological study. Sociodemographic data were collected from publically available resources for all athletes representing four countries (Canada, United States of America, Great Britain and Australia) at the 2014 Sochi Winter OGs and 2016 Rio Summer OGs. The prevalence of white and privately educated athletes were identified for each sport, country, and team with consideration and comparison to the general population. Access indices (i.e. the combined race socio-economic access index [CAI]) were developed to describe the relative distribution of white and privately educated athletes representing each sport, country and team compared to the respective general population. A total of 568 winter and 1643 summer athletes were included in this study. Privately educated athletes constituted 30.3% and 32.7% of winter and summer athletes, respectively; while 94.9% of winter and 81.7% of summer athletes were white. The CAIs of the Canadian, American, British and Australian winter Olympic teams were 0.52, 0.42, 0.61 and 0.45, respectively. The CAIs, for the Canadian, American, British and Australian summer Olympic teams were 0.89, 1.13, 0.82 and 0.83, respectively. Summer and winter sports with the greatest and least racial and socio-economic biases were identified. Racial and socio-economic biases were identified in both summer and winter Olympic sports; predominantly favouring white and privately educated Olympic athletes. These findings prompt further inquiry into barriers for sport-specific participation and advancement, in addition to the practice of providing substantial public resources in support for Olympic sports and athletes.

2010-01-01

To highlight the benefits and the need for sport science support for athletes with learning difficulties, and to reflect on our experience of working with the GB squad for athletes with learning difficulties. A review of key and relevant literature is presented, followed by a discussion of the sport science support provision and the issues that emerged in working with athletes with learning difficulties. Pre- and post- physiological tests along with evaluations of athletes' potential to benefit from sport psychology support were conducted. The aim of these tests was to provide information for the athletes and the coaches on fitness levels, to use this information to plan future training, and to identify how well the performance could be enhanced. A case study is presented for one athlete, who had competed in distance events. The focus is the psychological support that was provided. It is clear that athletes with learning difficulties require the same type of sports science support as their mainstream peers. However, sport scientists will need to consider ways to extend their practice in order to provide the appropriate level of support.

During the last decade, team confidence has received more and more attention in the sport psychology literature. Research has demonstrated that athletes who are more confident in their team's abilities exert more effort, set more challenging goals, are more resilient when facing adversities, and ultimately perform better. This article reviews the existing literature in order to provide more clarity in terms of the conceptualization and the operationalization of team confidence. We thereby distinguish between collective efficacy (i.e., process-oriented team confidence) and team outcome confidence (i.e., outcome-oriented team confidence). In addition, both the sources as well as the outcomes of team confidence will be discussed. Furthermore, we will go deeper into the dispersion of team confidence and we will evaluate the current guidelines on how to measure both types of team confidence. Building upon this base, the article then highlights interesting avenues for future research in order to further improve both our theoretical knowledge on team confidence and its application to the field.

Use of performance-enhancing supplements occurs at all levels of sports, from recreational athletes to professional athletes. Although some supplements do enhance athletic performance, many have no proven benefits and have adverse effects. Nutritional supplements are categorized into the following categories: I. Apparently Effective. II. Possibly Effective. III. Too Early To Tell. IV. Apparently Ineffective. This article will review 4 ergogenic supplements which are categorized in the first category--"Apparently Effective"--1) Buffer agents 2) Creatine 3) Caffeine and 4 Nitric Oxide. Given the widespread use of performance enhancing supplements, physicians, and dietitians should be prepared to counsel athletes about their effectiveness, safety and legality.

Role of sport medicine professionals in addressing psychosocial aspects of sport-injury rehabilitation: professional athletes' views.

Research from the sport medicine professional's (SMP's) perspective indicates that SMPs are often required to address psychosocial aspects of injuries during treatment. However, only a few authors have investigated injured athletes' experiences with these concerns. To explore injured professional athletes' views on the role of SMPs in the psychosocial aspects of sport-injury rehabilitation. Design : Qualitative study. Professional association football and rugby union clubs. Ten professional, male football (n = 4; 40%) and rugby union (n = 6; 60%) players (age = 22.4 ± 3.4 years). Data Collection and Analysis : We collected data using a semistructured interview guide, and the data were then transcribed and analyzed following the interpretative phenomenological analysis guidelines. We peer reviewed and triangulated the established emergent themes to establish trustworthiness. Athletes in our study viewed injuries as "part and parcel" of their sports. Despite normalizing sport injuries, athletes reported frequent feelings of frustration and self-doubt throughout the rehabilitation process. However, athletes' perceived the role of SMPs in injury rehabilitation as addressing physical concerns; any intervention aimed at psychosocial outcomes (eg, motivation, confidence) needed to be subtle and indirect. The SMPs working with injured athletes need to understand the psychosocial principles that underpin athletes' sport-injury processes and the effect psychosocial reactions can have on athletes. Moreover, SMPs must understand the self-regulatory processes that may take place throughout injury rehabilitation and be able to apply psychological principles in natural and subtle ways to aid athletes' self-regulatory abilities.

As the number of recreational athletes performing exercise and participating in competitions at a high-level increases, exercise-induced cardiac symptoms may become a more common problem, not least because recreational athletes often continue high-level exercise programs into advanced ages. We investigated the prevalence of cardiac symptoms and diagnoses among 201 athletes referred for cardiac evaluation at a Sports Cardiology Clinic in Denmark. To our knowledge, this is the first systematic study of athletes referred for suspected cardiac disease. The athletes were all well-trained recreational to elite athletes who participated in various sports with different training loads and a wide age span (13-66 years). All patients were referred by physicians, primarily their general practitioner (38%), and palpitations were the most common cardiac symptom (40%). Cardiac symptoms had a sensitivity of 86% in detecting cardiac disease and a specificity of 13%. Cardiac disease was diagnosed in 44% of the patients, and atrial fibrillation was the most prevalent diagnosis (7.5%). Cardiac diseases with therapeutic- or sports-related consequences for the patients were diagnosed in 28% of the population, but only 1% received a recommendation to avoid high-level sports indefinitely. © 2015 John Wiley & Sons A/S.

Sports-related dental injuries, such as tooth fracture, loosening, and avulsion, are a major concern among young athletes because they directly impair oral function. Although the preventive efficacy of mouthguards has been well established, the prevalence of sports-related dental injuries remains high among young athletes. The aim of this study is to identify the variables contributing to the risk of sports-related dental injuries by conducting a survey on large population of young athletes in Miyagi prefecture. A cross-sectional study was conducted with school-aged athletes (aged 6-15 years, n = 5735) using a self-reported questionnaire. The questionnaire examined general variables, including sex, age, and body mass index; sports-related variables, including sports-type, team level, activity schedule, break time, and verbal/physical abuse by coaches; and lifestyle variables related to free time, including screen-time and sleep duration. Their associations with sports-related dental injuries were examined using multivariate logistic regression models. The prevalence of sports-related dental injuries was 13.3% (763 of 5735 young athletes) and was higher in males (14.3%, 592 of 4132) than in females (10.7%, 171 of 1603; adjusted odds ratios [ORs] and 95% confidence intervals [CIs]: 1.48 [1.22-1.79], p < 0.001). After stratification according to sex, significant associations with the prevalence of sports-related dental injuries were evident for three variables-insufficient break time, verbal abuse, and physical punishment-in males (adjusted ORs [95% CI]: 1.35 [1.03-1.77], p = 0.032; 1.31 [1.05-1.62], p = 0.015; and 1.36 [1.06-1.75], p = 0.016, respectively) but not in females (adjusted ORs [95% CI]: 0.88 [0.53-1.47], p = 0.623; 1.29 [0.87-1.91], p = 0.206; and 0.97 [0.57-1.63], p = 0.894, respectively). Although our results might be based on the individual athlete's self-perception to the sports-related variables, our results suggest

2015-11-01

This article aimed to gain an understanding of the process of debriefing during major competitions in elite team sports. Debrief interviews were conducted with 9 head coaches. The interview data were used to identify how head coaches divided up the tasks given to staff and team members prior to, and during the post-match debriefing. Results showed that debriefing consisted of two steps: preparation and presentation. Preparation referred to four successive tasks. Presentation to the team of players consisted of eight tasks relating to transformational and transactional styles of leadership. Coaches were shown to divide the labor within the staff and team. The data tend to support the view that in elite team sports, coaches are both transformational and transactional leaders, adapting their style of leadership to the situation, athletes and time available. This study provides insights into the task-work and team-work underlying team functioning and division of labor. Copyright © 2015 Elsevier Ltd and The Ergonomics Society. All rights reserved.

The incidence and factors associated with illness in Paralympic athletes have not been documented. To determine the factors associated with illness in athletes participating in the London 2012 Paralympic Games. A cohort of 3565 athletes from 160 of the 164 participating countries in the London 2012 Paralympic Games were followed over a 14-day period (precompetition period=3 days, competition period=11 days; 49 910 athlete-days). Daily illness data were obtained from (1) teams with their own medical support who completed a daily illness log (78 teams, 3329 athletes) on a novel web-based system and (2) teams without their own medical support through the local organising committee database (82 teams, 236 athletes). Illness information from all athletes included age, gender, type of sport and the main system affected. Incidence rate (IR) of illness (illness per 1000 athlete-days) and factors associated with IR (time period, gender, age and sport). The IR of illness was 13.2 (95% CI 12.2 to 14.2). The highest IR of illness was in the respiratory system, followed by the skin, digestive, nervous and genitourinary systems. The IR in the precompetition period was similar to that in the competition period, but the IR was significantly higher in athletics compared with other sports. Age and gender were not independent predictors of illness. Illness is common in Paralympic athletes and the main factor associated with higher IR of illness was the type of sport (athletics).

2015-01-01

Context  Anecdotal and qualitative evidence has suggested that some clinicians face pressure from coaches and other personnel in the athletic environment to prematurely return athletes to participation after a concussion. This type of pressure potentially can result in compromised patient care. Objective  To quantify the extent to which clinicians in the collegiate sports medicine environment experience pressure when caring for concussed athletes and whether this pressure varies by the supervisory structure of the institution's sports medicine department, the clinician's sex, and other factors. Design  Cross-sectional study. Setting  Web-based survey of National College Athletic Association member institutions. Patients or Other Participants  A total of 789 athletic trainers and 111 team physicians from 530 institutions. Main Outcome Measure(s)  We asked participants whether they had experienced pressure from 3 stakeholder populations (other clinicians, coaches, athletes) to prematurely return athletes to participation after a concussion. Modifying variables that we assessed were the position (athletic trainer, physician) and sex of the clinicians, the supervisory structure of their institutions' sports medicine departments, and the division of competition in which their institutions participate. Results  We observed that 64.4% (n = 580) of responding clinicians reported having experienced pressure from athletes to prematurely clear them to return to participation after a concussion, and 53.7% (n = 483) reported having experienced this pressure from coaches. Only 6.6% (n = 59) reported having experienced pressure from other clinicians to prematurely clear an athlete to return to participation after a concussion. Clinicians reported greater pressure from coaches when their departments were under the supervisory purview of the athletic department rather than a medical institution. Female clinicians reported greater pressure from coaches than male

Hemophilia in Sports: A Case Report and Prophylactic Protocol

PubMed Central

Maffet, Mark; Roton, Jimmy

2017-01-01

Objective: To describe a successful prophylactic protocol for managing an athlete with hemophilia playing at a high level of contact sports. Background: Published data show that team physicians are not comfortable either treating athletes with bleeding disorders or allowing them to participate in contact sports. Much of the literature historically has recommended against allowing athletes with bleeding disorders to play sports at all and certainly against playing contact sports. Hemophilia treatment can now include prophylactic injections of recombinant factor VIII to prevent bleeding episodes. Modern treatments hold the promise of allowing athletes with hemophilia to participate in contact sports. Differential Diagnosis: Mild, moderate, or severe hemophilia; von Willebrand disease; other factor deficiencies. Treatment: A treatment protocol was developed that included prophylactic factor VIII injections on a regular basis and when the athlete was injured. Uniqueness: This is the first published case report of an athlete with known hemophilia being successfully treated and participating in National Collegiate Athletic Association collegiate basketball for 2 full seasons. Conclusions: Sports medicine teams can successfully manage an athlete with hemophilia playing a contact sport. PMID:27863189

Broad criteria for abnormal electrocardiogram (ECG) findings, requiring additional testing, have been recommended for preparticipation exams (PPE) of athletes. As these criteria have not considered the sport in which athletes participate, we examined the effect of sports on the computerized ECG measurements obtained in college athletes. During the Stanford 2007 PPE, computerized 12-lead ECGs (Schiller AG) were obtained in 641 athletes (350 male/291 female, age 19.5 ± 2 years). Athletes were engaged in 22 different sports and were grouped into 16 categories: baseball/softball, basketball, crew, crosscountry, fencing, field events, football linemen, football other positions, golf, gymnastics, racquet sports, sailing, track/field, volleyball, water sports, and wrestling. The analysis focused on ECG leads V2, aVF and V5 which provide a three-dimensional representation of the heart's electrical activity. As marked ECG differences exist between males and females, the data are presented by gender. In males, ANOVA analysis yielded significant ECG differences between sports for heart rate, QRS duration, QTc, J-amplitude in V2 and V5, spatial vector length (SVL) of the P wave, SVL R wave, and SVL T wave, and RS(sum) (p < 0.05). In females ECG differences between sports were found for heart rate, QRS duration, QRS axis and SVL T wave (p < 0.05). Poor correlations were found between body dimensions and ECG measurements (r < 0.50). Significant ECG changes exist between college athletes participating in different sports, and these differences were more apparent in males than females. Therefore, sport-specific ECG criteria for abnormal ECG findings should be developed to obtain a more useful approach to ECG screening in athletes.

Context: Research from the sport medicine professional's (SMP's) perspective indicates that SMPs are often required to address psychosocial aspects of injuries during treatment. However, only a few authors have investigated injured athletes' experiences with these concerns. Objective: To explore injured professional athletes' views on the role of SMPs in the psychosocial aspects of sport-injury rehabilitation. Design Qualitative study. Setting: Professional association football and rugby union clubs. Patients or Other Participants: Ten professional, male football (n = 4; 40%) and rugby union (n = 6; 60%) players (age = 22.4 ± 3.4 years). Data Collection and Analysis We collected data using a semistructured interview guide, and the data were then transcribed and analyzed following the interpretative phenomenological analysis guidelines. We peer reviewed and triangulated the established emergent themes to establish trustworthiness. Results: Athletes in our study viewed injuries as “part and parcel” of their sports. Despite normalizing sport injuries, athletes reported frequent feelings of frustration and self-doubt throughout the rehabilitation process. However, athletes' perceived the role of SMPs in injury rehabilitation as addressing physical concerns; any intervention aimed at psychosocial outcomes (eg, motivation, confidence) needed to be subtle and indirect. Conclusions: The SMPs working with injured athletes need to understand the psychosocial principles that underpin athletes' sport-injury processes and the effect psychosocial reactions can have on athletes. Moreover, SMPs must understand the self-regulatory processes that may take place throughout injury rehabilitation and be able to apply psychological principles in natural and subtle ways to aid athletes' self-regulatory abilities.

The purpose of this study was to examine executive functions in team sport athletes with and without a history of concussion. Executive functions comprise many cognitive processes including, working memory, attention and multi-tasking. Past research has shown that concussions cause difficulties in vestibular-visual and vestibular-auditory dual-tasking, however, visual-auditory tasks have been examined rarely. Twenty-nine intercollegiate varsity ice hockey athletes (age = 19.13, SD = 1.56; 15 females) performed an experimental dual-task paradigm that required simultaneously processing visual and auditory information. A brief interview, event description and self-report questionnaires were used to assign participants to each group (concussion, no-concussion). Eighteen athletes had a history of concussion and 11 had no concussion history. The two tests involved visuospatial working memory (i.e., Corsi block test) and auditory tone discrimination. Participants completed both tasks individually, then simultaneously. Two outcome variables were measured, Corsi block memory span and auditory tone discrimination accuracy. No differences were shown when each task was performed alone; however, athletes with a history of concussion had a significantly worse performance on the tone discrimination task in the dual-task condition. In conclusion, long-term deficits in executive functions were associated with a prior history of concussion when cognitive resources were stressed. Evaluations of executive functions and divided attention appear to be helpful in discriminating participants with and without a history concussion.

Background: Youth participation in organized sports in the United States is rising, with many athletes focusing on a single sport at an increasingly younger age. Purpose: To retrospectively compare single-sport specialization in current high school (HS), collegiate, and professional athletes with regard to the rate and age of specialization, the number of months per year of single-sport training, and the athlete’s perception of injury related to specialization. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A survey was distributed to HS, collegiate, and professional athletes prior to their yearly preparticipation physical examination. Athletes were asked whether they had chosen to specialize in only 1 sport, and data were then collected pertaining to this decision. Results: A total of 3090 athletes completed the survey (503 HS, 856 collegiate, and 1731 professional athletes). A significantly greater percentage of current collegiate athletes specialized to play a single sport during their childhood/adolescence (45.2% of HS athletes, 67.7% of collegiate athletes, and 46.0% of professional athletes; P < .001). The age of single-sport specialization differed between groups and occurred at a mean age of 12.7 ± 2.4 (HS), 14.8 ± 2.5 (collegiate), and 14.1 ± 2.8 years (professional) (P < .001). Current HS (39.9%) and collegiate athletes (42.1%) recalled a statistically greater incidence of sport-related injury than current professional athletes (25.4%) (P < .001). The majority (61.7%) of professional athletes indicated that they believed specialization helps the athlete play at a higher level, compared with 79.7% of HS and 80.6% of collegiate athletes (P < .001). Notably, only 22.3% of professional athletes said they would want their own child to specialize to play only 1 sport during childhood/adolescence. Conclusion: This study provides a foundation for understanding current trends in single-sport specialization in all athletic levels. Current

Sleep is generally regarded as a valuable resource for psychological and physiological well-being. Although the effects of sleep on athletic performance have been acknowledged in sport science, few studies have investigated the prevalence of sleep problems and their effects on elite athletes before a sport event. In this study, 632 German athletes from various sports were asked about their sleep habits during the night(s) before an important competition or game. The findings indicate that 65.8% of the athletes experienced poor sleep in the night(s) before a sports event at least once in their lives and a similarly high percentage (62.3%) had this experience at least once during the previous 12 months. Athletes of individual sports reported more sleep difficulties than athletes of team sports. The main sleep problem was not being able to fall asleep. Internal factors such as nervousness and thoughts about the competition were rated highest for causing sleep problems. Most athletes stated that disturbed sleep had no influence on their athletic performance; however, athletes also reported effects such as a bad mood the following day, increased daytime sleepiness, and worse performance in the competition or game. The differences between individual and team sports indicate that athletes in some sports need more help than those in other sports in managing sleep problems.

The aim of this study was to investigate the methods adopted to reduce body mass (BM) in competitive athletes from the grappling (judo, jujitsu) and striking (karate and tae kwon do) combat sports in the state of Minas Gerais, Brazil. An exploratory methodology was employed through descriptive research, using a standardized questionnaire with objective questions self-administered to 580 athletes (25.0 ± 3.7 yr, 74.5 ± 9.7 kg, and 16.4% ± 5.1% body fat). Regardless of the sport, 60% of the athletes reported using a method of rapid weight loss (RWL) through increased energy expenditure. Strikers tend to begin reducing BM during adolescence. Furthermore, 50% of the sample used saunas and plastic clothing, and only 26.1% received advice from a nutritionist. The authors conclude that a high percentage of athletes uses RWL methods. In addition, a high percentage of athletes uses unapproved or prohibited methods such as diuretics, saunas, and plastic clothing. The age at which combat sport athletes reduce BM for the first time is also worrying, especially among strikers.

2014-01-01

Objective Considering the high number of stressors encountered in the context of elite sports, a high sense of coherence (SOC) is crucial to allow athletes to maintain their health from both short- and long-term perspectives. The aim of this cross-sectional study was to investigate SOC in a population of elite athletes, focusing on identification of subsets of athletes with particularly high and low SOC scores, and any related predictors. The elite athletes' SOC scores were also evaluated for differences with those of the general population of Germany; whether a correlation between SOC and subjective health existed was additionally examined. Method In total, 698 male and female elite athletes, drawn from Germany's highest-level national track and field squads, and first and second division handball teams, completed a survey that included the SOC-L9 Scale and measures of subjective health, sociodemographic information, and the number of injury lay-offs experienced during the athletes' careers to date. Results Classification tree analysis reveals six contrast groups with varying SOC scores. Several interacting factors determine the group to which an athlete belongs. Together with overuse injuries, additional factors are age, gender, and completed/not completed apprenticeship/degree. Female athletes aged between 19 and 25, who had already been subject to lay-offs due to overuse injuries, comprise the group with the lowest SOC scores. Overall, the SOC of elite athletes is slightly lower than in the general population. In accordance with other studies, a stronger SOC is also correlated significantly with better global subjective health. Conclusion The identification of contrast groups with varying SOC scores contributes to the development of more targeted salutogenetic health promotion programs. Such programs would ideally include learning modules pertaining to coping with overuse injuries, as well as social support systems aiming to effectively combine education and

This article examines the role of gambling as an addictive disorder experienced by athletes, both college and professional. Gambling may often be seen as a comorbid factor with other addictions and with depression among athletes. The focus on addictions among athletes has gained considerable attention among sports medicine clinicians. Diagnostic indicators, risk and protective factors, and a stage model of addiction among athletes are addressed. An algorithm and pathway of care for athletes with an addictive disorder is offered as are recommendations that sports physicians, sports medicine specialists, coaches and counsellors need to address athletes who have an addictive disorder.

Payne, Simon Mark; Hudson, Joanne; Akehurst, Sally; Ntoumanis, Nikos

2013-06-01

Impression motivation is an important individual difference variable that has been under-researched in sport psychology, partly due to having no appropriate measure. This study was conducted to design a measure of impression motivation in team-sport athletes. Construct validity checks decreased the initial pool of items, factor analysis (n = 310) revealed the structure of the newly developed scale, and exploratory structural equation modeling procedures (n = 406) resulted in a modified scale that retained theoretical integrity and psychometric parsimony. This process produced a 15-item, 4-factor model; the Impression Motivation in Sport Questionnaire-Team (IMSQ-T) is forwarded as a valid measure of the respondent's dispositional strength of motivation to use self-presentation in striving for four distinct interpersonal objectives: self-development, social identity development, avoidance of negative outcomes, and avoidance of damaging impressions. The availability of this measure has contributed to theoretical development, will facilitate research, and offers a tool for use in applied settings.

The purpose of this study was to investigate fear of failure in highly competitive junior athletes and the association with psychological stress and burnout. In total 258 athletes (152 males and 108 females) ranged in age from 15 to 19 years (M = 17.4 years, SD = 1.08) participated. Athletes competed in variety of sports including both team and individual sports. Results showed in a variable-oriented approach using regression analyses that one dimension, fear of experiencing shame and embarrassment had a statistically significant effect on perceived psychological stress and one dimension of burnout, reduced sense of accomplishment. However, adopting a person-oriented approach using latent class analysis, we found that athletes with high levels of fear failure on all dimensions scored high on burnout. We also found another class with high scores on burnout. These athletes had high scores on the individual-oriented dimensions of fear of failure and low scores on the other oriented fear of failure dimensions. The findings indicate that fear of failure is related to burnout and psychological stress in athletes and that this association is mainly associated with the individual-oriented dimensions of fear of failure. © 2016 John Wiley & Sons A/S.

Background Hamstring strain and anterior cruciate ligament injuries are, respectively, the most prevalent and serious non-contact occurring injuries in team sports. Specific biomechanical and neuromuscular variables have been used to estimate the risk of incurring a non-contact injury in athletes. Objective The aim of this study was to systematically review the evidences for the effectiveness of injury prevention protocols to modify biomechanical and neuromuscular anterior cruciate and/or hamstring injuries associated risk factors in uninjured team sport athletes. Data Sources PubMed, Science Direct, Web of Science, Cochrane Libraries, U.S. National Institutes of Health clinicaltrials.gov, Sport Discuss and Google Scholar databases were searched for relevant journal articles published until March 2015. A manual review of relevant articles, authors, and journals, including bibliographies was performed from identified articles. Main Results Nineteen studies were included in this review. Four assessment categories: i) landing, ii) side cutting, iii) stop-jump, and iv) muscle strength outcomes, were used to analyze the effectiveness of the preventive protocols. Eight studies using multifaceted interventions supported by video and/or technical feedback showed improvement in landing and/or stop-jump biomechanics, while no effects were observed on side-cutting maneuver. Additionally, multifaceted programs including hamstring eccentric exercises increased hamstring strength, hamstring to quadriceps functional ratio and/or promoted a shift of optimal knee flexion peak torque toward a more open angle position. Conclusions Multifaceted programs, supported by proper video and/or technical feedback, including eccentric hamstring exercises would positively modify the biomechanical and or neuromuscular anterior cruciate and/or hamstring injury risk factors.

This study examine 53 European elite deaf athletes for their family's hearing status, use of hearing aids, communication preference, education in integrated or segregated settings, family members' encouragement for participation in sports, coach preference (hearing or deaf), and conditions for competitive events with deaf or hearing athletes. These data were gathered through semi-structured interviews administered in the athlete's native language. Deaf athletes reported that when given the opportunity to compete with hearing athletes, it enhanced their opportunity for competition. Participating in sports with hearing athletes played an important role in the integration of deaf athletes into mainstream society. If adaptations to communication can be made in these integrated settings, the ability of deaf athletes to participate in such settings will increase.

The purpose of this study was to gain insight in barriers and facilitators of sports in paralympic athletes. An online questionnaire was distributed through the Netherlands Olympic Committee and National Sports Confederation to determine personal and environmental barriers and facilitators of sports participation. The International Classification of Functioning, Disability and Health model and theory of planned behavior were used to respectively categorize the results in environmental and personal factors, and attitude, subjective norm and perceived behavioral control. Seventy-six Dutch Paralympic athletes completed the questionnaire (51% response rate). Barriers and facilitators experienced by ambulant and wheelchair athletes were compared. Most frequently mentioned personal barrier was dependency of others (22%), while most frequently mentioned environmental barrier was lack of sports facilities (30%). Wheelchair athletes mentioned more barriers (median = 3, interquartile range: 0.5-6), than ambulant athletes (median = 1.0,interquartile range:0.0-3.0, P = 0.023). One-third of the athletes did not experience any barriers. Most frequently mentioned personal facilitators to initiate sports participation were fun (78%), health (61%), and competition (53%). Most frequently mentioned environmental facilitator was social support (40%). This study indicated that barriers of sport were mostly environmental, while facilitators were usually personal factors. Attitude and subjective norm were considered the most important components for intention to participation in sports. The facilitators outweighed the barriers and kept the athletes being active in sports. © 2013 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Weight Management Practices of Australian Olympic Combat Sport Athletes.

Combat sport athletes undertake chronic and rapid weight loss (RWL) practices to qualify for weight divisions lower than their training weight. Variation between sports in the prevalence, methods, and magnitude of weight loss as well as recovery practices may be influenced by factors including competition level and culture. Differences in methodologies of previous research in combat sports make direct comparisons difficult; thus, this study aimed to examine weight loss practices among all Olympic combat sports in Australia, using standardized methodology. High-caliber competitors in wrestling, boxing, judo, and taekwondo (n = 260) at Australian competitions were surveyed using a validated tool that provides quantification of how extreme an athlete's weight loss practices are: the rapid weight loss score (RWLS). Additional qualitative and quantitative survey data were also collected. Neither sport, sex, nor weight division group had an effect on RWLS; however, a significant effect of athlete caliber was detected (F 2,215  = 4.953, mean square error = 4.757, P = .00792). Differences between sports were also evident for most weight ever lost in order to compete (H = 19.92, P = .0002), age at which weight cutting began (H = 16.34, P = .001), and selected methods/patterns of RWL (P < .001). Weight cycling between competitions was common among all sports as were influences on athlete's behaviors. Although many similarities in weight loss practices and experiences exist between combat sports, specific differences were evident. Nuanced, context/culturally specific guidelines should be devised to assist fighters' in optimizing performance while minimizing health implications.

Ethical issues in sports medicine: a review and justification for ethical decision making and reasoning.

PubMed

Greenfield, Bruce H; West, Charles Robert

2012-11-01

Ethical issues present a challenge for health care professionals working with athletes of sports teams. Health care professionals-including the team physician, the physical therapist, and the athletic trainer-are faced with the challenge of returning an athlete to competition as quickly as possible but as safely as possible. Conflicts of interest arise due to conflicting obligations of the team physician to the athlete and other members of the sports organization, including coaches and the team owner. The multiple stakeholders involved in sports teams challenge the traditional notion of confidentiality and autonomy. The aims of this article are to explicate the ethics of sports medicine, highlight the ethical issues, and provide some strategies and suggestions for ethical decision making.

Predictability of physiological testing and the role of maturation in talent identification for adolescent team sports.

PubMed

Pearson, D T; Naughton, G A; Torode, M

2006-08-01

Entrepreneurial marketing of sport increases demands on sport development officers to identify talented individuals for specialist development at the youngest possible age. Talent identification results in the streamlining of resources to produce optimal returns from a sports investment. However, the process of talent identification for team sports is complex and success prediction is imperfect. The aim of this review is to describe existing practices in physiological tests used for talent identification in team sports and discuss the impact of maturity-related differences on the long term outcomes particularly for male participants. Maturation is a major confounding variable in talent identification during adolescence. A myriad of hormonal changes during puberty results in physical and physiological characteristics important for sporting performance. Significant changes during puberty make the prediction of adult performance difficult from adolescent data. Furthermore, for talent identification programs to succeed, valid and reliable testing procedures must be accepted and implemented in a range of performance-related categories. Limited success in scientifically based talent identification is evident in a range of team sports. Genetic advances challenge the ethics of talent identification in adolescent sport. However, the environment remains a significant component of success prediction in sport. Considerations for supporting talented young male athletes are discussed.

2017-07-01

Ankle sprains are among the most common injuries experienced by collegiate athletes. The type of ankle sprain is rarely differentiated in epidemiological studies. This differentiation is necessary, as each ankle sprain type has a unique injury mechanism and recovery period. High ankle sprains commonly result in long recovery periods. Thus, a further examination of the epidemiology of high ankle sprains is warranted. To describe the epidemiology of high ankle sprains in National Collegiate Athletic Association (NCAA) sports during the 2009/2010-2014/2015 academic years. Descriptive epidemiology study. NCAA Injury Surveillance Program high ankle sprain data and athlete-exposures (AEs) from 25 sports were evaluated. Certified athletic trainers recorded sport-related injury, event, and AE data during team-sanctioned events. High ankle sprain injury rates per 10,000 AEs were calculated. Percentage distributions were calculated for the amount of time lost from sport and percentage of recurrent injuries. Injury rate ratios (RRs) and 95% CIs compared injury rates by event type, participation restriction time, and sex. 95% CIs not containing 1.00 were considered statistically significant. The overall high ankle sprain injury rate was 1.00 per 10,000 AEs. Overall, 56.7% of high ankle sprain injuries occurred during competitions, and 9.8% of high ankle sprain injuries were recurrent. Men's football (2.42/10,000 AEs), wrestling (2.11/10,000 AEs), and ice hockey (1.19/10,000 AEs) had the highest high ankle sprain injury rates. In sex-comparable sports, men had higher injury rates (RR, 1.77; 95% CI, 1.28-2.44). Player contact was the most common injury mechanism (60.4%), and 69.0% of injuries resulted in ≥1 day of participation restriction, with 47.1% resulting in ≥7 days of participation restriction and 15.8% resulting in >21 days of participation restriction. High ankle sprains resulted in significant participation restriction time from sport participation. The majority of

The purpose of the study was to evaluate the results of surgical treatment in athletes with associated intra-articular hip pathology and extra-articular sports pubalgia. Between December 2003 and September 2009, 37 hips (mean patient age, 25 years) were diagnosed with both symptomatic athletic pubalgia and symptomatic intra-articular hip joint pathology. There were 8 professional athletes, 15 collegiate athletes, 5 elite high school athletes, and 9 competitive club athletes. Outcomes included an evaluation regarding return to sports and modified Harris Hip Score, Short Form 12 score, and visual analog scale score. We evaluated 37 hips at a mean of 29 months (range, 12 to 78 months) after the index surgery. Thirty-one hips underwent thirty-five athletic pubalgia surgeries. Hip arthroscopy was performed in 32 hips (30 cases of femoroacetabular impingement treatment, 1 traumatic labral tear, and 1 borderline dysplasia). Of 16 hips that had athletic pubalgia surgery as the index procedure, 4 (25%) returned to sports without limitations, and 11 (69%) subsequently had hip arthroscopy at a mean of 20 months after pubalgia surgery. Of 8 hips managed initially with hip arthroscopy alone, 4 (50%) returned to sports without limitations, and 3 (43%) had subsequent pubalgia surgery at a mean of 6 months after hip arthroscopy. Thirteen hips had athletic pubalgia surgery and hip arthroscopy at one setting. Concurrent or eventual surgical treatment of both disorders led to improved postoperative outcomes scores (P < .05) and an unrestricted return to sporting activity in 89% of hips (24 of 27). When surgery only addressed either the athletic pubalgia or intra-articular hip pathology in this patient population, outcomes were suboptimal. Surgical management of both disorders concurrently or in a staged manner led to improved postoperative outcomes scoring and an unrestricted return to sporting activity in 89% of hips.

Determine the percentage of skeletally immature athletes returning to sports after anterior cruciate ligament (ACL) injury and reconstruction. Retrospective case series. Boston Children's Hospital Division of Sports Medicine. Eligible participants were identified by chart review. Males and females aged ≤14 year old who were greater than 2 years after ACL reconstruction surgery seen between January 2001 and May 2009. A total of 250 patients completed the questionnaires. Age, sex, mechanism, and sport played at time of ACL injury. Response to the survey was 75% (250 of 333) which was analyzed using descriptive statistics to provide a summary of the study cohort. Kaplan-Meier survivorship analysis was applied to determine time to return to sports participation after ACL reconstruction with Greenwood formula used to calculate 95% confidence intervals around the estimated percentage returning at 6, 9, 12, 18, and 24-month follow-up. After undergoing ACL reconstruction, 96% of skeletally immature athletes are able to return to sports at the same skill level. Median time to return to sports was 9 months postoperative, with most athletes returning to sports (85%) by 12 months. After undergoing ACL reconstruction, most child athletes are able to return to sports and 50% of these athletes return within 9 months after surgery. After undergoing ACL reconstruction, 96% of athletes ≤14 year old are able to return to sports at the same skill level. Median time to return to sports was 9 months postoperative, with most athletes returning to sports (85%) by 12 months. In our study, patients cited physical limitation, loss of interest in sport, and fear of reinjury as reasons for not returning to previous level of sport. Return to sport may be improved by additional research into sports-specific training and rehabilitation in this cohort.

This study examined Australian athletes' support for athletes' role in promoting physical activity and obesity prevention, the acceptability of unhealthy products promotion in sport, and their own health behaviours. Surveys were conducted with (n = 1990) elite and sub-elite athletes recruited from 22 sports across Australia. Athletes' perceptions and behaviours were analysed across demographic and sport-related factors (e.g. individual vs team sport) and correlations calculated between perceptions and health behaviours. Most respondents supported a role for athletes in promoting physical activity and obesity prevention, and disagreed that athletes should promote unhealthy foods and alcohol (73.9%). Athletes reported low smoking rates, but high rates of binge drinking. Female, younger, individual and amateur athletes had more health-positive perceptions and healthier behaviours than older, male, team and professional athletes. More sympathy towards junk food and alcohol advertising in sport and less support for athletes as role models were associated with more unhealthy behaviours. Elite athletes are receptive to supporting health promotion through sport and many are not in agreement with the promotion of unhealthy products in sport or by sports people. Improving elite athletes' health behaviours would benefit not only the individual but also health promotion within elite sport.

A return to their preinjury level of sport is frequently expected within 1 year after anterior cruciate ligament (ACL) reconstruction, yet up to two-thirds of athletes may not have achieved this milestone. The subsequent sports participation outcomes of athletes who have not returned to their preinjury level sport by 1 year after surgery have not previously been investigated. To investigate return-to-sport rates at 2 years after surgery in athletes who had not returned to their preinjury level sport at 1 year after ACL reconstruction. Case series; Level of evidence, 4. A consecutive cohort of competitive- and recreational-level athletes was recruited prospectively before undergoing ACL reconstruction at a private orthopaedic clinic. Participants were followed up at 1 and 2 years after surgery with a sports activity questionnaire that collected information regarding returning to sport, sports participation, and psychological responses. An independent physical therapist evaluated physical function at 1 year using hop tests and the International Knee Documentation Committee knee examination form and subjective knee evaluation. A group of 122 competitive- and recreational-level athletes who had not returned to their preinjury level sport at 1 year after ACL reconstruction participated. Ninety-one percent of the athletes returned to some form of sport after surgery. At 2 years after surgery, 66% were playing sport, with 41% playing their preinjury level of sport and 25% playing a lower level of sport. Having a previous ACL reconstruction to either knee, poorer hop-test symmetry and subjective knee function, and more negative psychological responses were associated with not playing the preinjury level sport at 2 years. Most athletes who were not playing sport at 1 year had returned to some form of sport within 2 years after ACL reconstruction, which may suggest that athletes can take longer than the clinically expected time of 1 year to return to sport. However, only 2

AIM: To investigate the association between sports hernias and femoroacetabular impingement (FAI) in athletes. METHODS: PubMed, MEDLINE, CINAHL, Embase, Cochrane Controlled Trials Register, and Google Scholar databases were electronically searched for articles relating to sports hernia, athletic pubalgia, groin pain, long-standing adductor-related groin pain, Gilmore groin, adductor pain syndrome, and FAI. The initial search identified 196 studies, of which only articles reporting on the association of sports hernia and FAI or laparoscopic treatment of sports hernia were selected for systematic review. Finally, 24 studies were reviewed to evaluate the prevalence of FAI in cases of sports hernia and examine treatment outcomes and evidence for a common underlying pathogenic mechanism. RESULTS: FAI has been reported in as few as 12% to as high as 94% of patients with sports hernias, athletic pubalgia or adductor-related groin pain. Cam-type impingement is proposed to lead to increased symphyseal motion with overload on the surrounding extra-articular structures and muscle, which can result in the development of sports hernia and athletic pubalgia. Laparoscopic repair of sports hernias, via either the transabdominal preperitoneal or extraperitoneal approach, has a high success rate and earlier recovery of full sports activity compared to open surgery or conservative treatment. For patients with FAI and sports hernia, the surgical management of both pathologies is more effective than sports pubalgia treatment or hip arthroscopy alone (89% vs 33% of cases). As sports hernias and FAI are typically treated by general and orthopedic surgeons, respectively, a multidisciplinary approach for diagnosis and treatment is recommended for optimal treatment of patients with these injuries. CONCLUSION: The restriction in range of motion due to FAI likely contributes to sports hernias; therefore, surgical treatment of both pathologies represents an optimal therapy. PMID:26380829

The relationship between action anticipation and emotion recognition in athletes of open skill sports.

PubMed

Shih, Yu-Ling; Lin, Chia-Yen

2016-08-01

Action anticipation plays an important role in the successful performance of open skill sports, such as ball and combat sports. Evidence has shown that elite athletes of open sports excel in action anticipation. Most studies have targeted ball sports and agreed that information on body mechanics is one of the key determinants for successful action anticipation in open sports. However, less is known about combat sports, and whether facial emotions have an influence on athletes' action anticipation skill. It has been suggested that the understanding of intention in combat sports relies heavily on emotional context. Based on this suggestion, the present study compared the action anticipation performances of taekwondo athletes, weightlifting athletes, and non-athletes and then correlated these with their performances of emotion recognition. This study primarily found that accurate action anticipation does not necessarily rely on the dynamic information of movement, and that action anticipation performance is correlated with that of emotion recognition in taekwondo athletes, but not in weightlifting athletes. Our results suggest that the recognition of facial emotions plays a role in the action prediction in such combat sports as taekwondo.

Vision-based measures have been shown to be useful markers in multiple sclerosis (MS), Alzheimer and Parkinson disease. Therefore, these testing paradigms may have applications to populations explaining repetitive head trauma that has been associated with long-term neurodegenerative sequelae. We investigated retinal structure and visual function in professional collision sport athletes compared to age- and race-matched control participants. In this cross-sectional study, participants underwent spectral-domain optical coherence tomography (OCT) measurements of peripapillary retinal nerve fiber layer (RNFL) and macular ganglion cell complex (GCC = ganglion cell + inner plexiform layers) thickness. High-contrast visual acuity (100% level), low-contrast letter acuity (LCLA) (1.25% and 2.5% levels), and King-Devick Test of rapid number naming performance were administered. Vision-specific quality of life (QOL) measures were assessed. Among 46 collision sport athletes (boxing, n = 14; football, n = 29; ice hockey, n = 3) and 104 control participants, average RNFL thickness was a significant predictor of athlete vs control status with athletes demonstrating 4.8-μm of thinning compared to controls (P = 0.01, generalized estimating equation [GEE] models accounting for age and within-subject, intereye correlations). Athlete vs control status was not a predictor of RNFL thickness for the subgroup of football players in this cohort (P = 0.60). Binocular (P = 0.001) and monocular (P = 0.02) LCLA at 2.5% contrast and vision-specific QOL (P = 0.04) were significant predictors of athlete vs control status (GEE models accounting for age and within-subject, intereye correlations). Rapid number naming performance times were not significantly different between the control and athlete groups. This study showed that retinal axonal and neuronal loss is present among collision sport athletes, with most notable differences seen in boxers. These findings are accompanied by reductions in

The primary purpose of this article is to review the literature on para sport athletic identity and provide avenues for future research direction. First, the authors briefly describe the existing quantitative and qualitative research on para sport athletic identity and, thereby, illustrate the complexities para sport athletes experience regarding the way they describe their participation in competitive sport. Next, the authors describe how para sport athletes with acquired permanent disabilities and congenital disabilities face similar, yet unique, identity-related challenges. Finally, the authors argue that future researchers should consider examining para sport athletes' identity through narrative identity. Copyright © 2018 Elsevier Inc. All rights reserved.

To examine differences in lung function among sports that are of a similar nature and to determine which anthropometric/demographic characteristics correlate with lung volumes and flows. This was a cross-sectional study involving elite male athletes (N = 150; mean age, 21  4 years) engaging in one of four different sports, classified according to the type and intensity of exercise involved. All athletes underwent full anthropometric assessment and pulmonary function testing (spirometry). Across all age groups and sport types, the elite athletes showed spirometric values that were significantly higher than the reference values. We found that the values for FVC, FEV1, vital capacity, and maximal voluntary ventilation were higher in water polo players than in players of the other sports evaluated (p < 0.001). In addition, PEF was significantly higher in basketball players than in handball players (p < 0.001). Most anthropometric/demographic parameters correlated significantly with the spirometric parameters evaluated. We found that BMI correlated positively with all of the spirometric parameters evaluated (p < 0.001), the strongest of those correlations being between BMI and maximal voluntary ventilation (r = 0.46; p < 0.001). Conversely, the percentage of body fat correlated negatively with all of the spirometric parameters evaluated, correlating most significantly with FEV1 (r = -0.386; p < 0.001). Our results suggest that the type of sport played has a significant impact on the physiological adaptation of the respiratory system. That knowledge is particularly important when athletes present with respiratory symptoms such as dyspnea, cough, and wheezing. Because sports medicine physicians use predicted (reference) values for spirometric parameters, the risk that the severity of restrictive disease or airway obstruction will be underestimated might be greater for athletes.

What Performance Characteristics Determine Elite Versus Nonelite Athletes in the Same Sport?

Context: There are significant data comparing elite and nonelite athletes in anaerobic field and court sports as well as endurance sports. This review delineates specific performance characteristics in the elite athlete and may help guide rehabilitation. Evidence Acquisition: A Medline search from April 1982 to April 2012 was undertaken for articles written in English. Additional references were accrued from reference lists of research articles. Results: In the anaerobic athlete, maximal power production was consistently correlated to elite performance. Elite performance in the endurance athlete is more ambiguous, however, and appears to be related to the dependent variable investigated in each individual study. Conclusion: In anaerobic field and court sport athletes, maximal power output is most predictive of elite performance. In the endurance athlete, however, it is not as clear. Elite endurance athletes consistently test higher than nonelite athletes in running economy, anaerobic threshold, and VO2max. PMID:24427430

The present study set out to assess the impact of attributional beliefs about success on the susceptibility for doping use in adolescent athletes. The sample consisted of 309 adolescent athletes participating in both team and individual sports. Participants completed a battery of questionnaires including Beliefs about the Causes of Success in Sport Questionnaire (BACSSQ), current and past doping use, and measures of attitudes, norms, situational temptation and social desirability. Variance reduction rate analysis revealed that social desirability did not act as a confounder in the relationship between doping susceptibility and its predictors. With regard to beliefs about the causes of success dimensions, only deception emerged as a significant predictor of doping use susceptibility over and above the effects of well-established social-cognitive predictors of doping intentions and use. These findings imply that beliefs about the causes of success in youth sports may comprise another dimension of risk factors for doping susceptibility and use.

Context: Coaches, athletic trainers (ATs), strength and conditioning specialists (SCSs), and registered dietitians are common nutrition resources for athletes, but coaches, ATs, and SCSs might offer only limited nutrition information. Little research exists about sports nutrition knowledge and current available resources for nutrition information for athletes, coaches, ATs, and SCSs. Objective: To identify resources of nutrition information that athletes, coaches, ATs, and SCSs use; to examine nutrition knowledge among athletes, coaches, ATs, and SCSs; and to determine confidence levels in the correctness of nutrition knowledge questions within all groups. Design: Cross-sectional study. Setting: National Collegiate Athletic Association Division I, II, and III institutions across the United States. Patients and Other Participants: The 579 participants consisted of athletes (n = 185), coaches (n = 131), ATs (n = 192), and SCSs (n = 71). Main Outcome Measure(s): Participants answered questions about nutrition resources and domains regarding basic nutrition, supplements and performance, weight management, and hydration. Adequate sports nutrition knowledge was defined as an overall score of 75% in all domains (highest achievable score was 100%). Results: Participants averaged 68.5% in all domains. The ATs (77.8%) and SCSs (81.6%) had the highest average scores. Adequate knowledge was found in 35.9% of coaches, 71.4% of ATs, 83.1% of SCSs, and only 9% of athletes. The most used nutrition resources for coaches, ATs, and SCSs were registered dietitians. Conclusions: Overall, we demonstrated that ATs and SCSs have adequate sports nutrition knowledge, whereas most coaches and athletes have inadequate knowledge. Athletes have frequent contact with ATs and SCSs; therefore, proper nutrition education among these staff members is critical. We suggest that proper nutrition programming should be provided for athletes, coaches, ATs, and SCSs. However, a separate nutrition program

In the general population visual-spatial ability is better in males, due to the influence of biological and socio-cultural factors. We know that sport activity improves motor skills. The aim of this work is to determine if these gender differences exist in young athletes. The orientation test described by Terzi and standardized by Cesaroni, used to measure spatial ability, was carried out on 60 volleyball or 60 tennis athletes as well as on 60 non-sporting subjects. The data analysis revealed a worse performance for non-athletes in comparison with athletes in both components of test (p < 0.0001; p = 0.04), with no differences between the volleyball and tennis groups. As far as gender comparison is concerned, as expected in the non- sport group the males presented better values (p < 0.001; p = 0.006). However in both sports groups there weren't any gender differences in either part of the test (p = 0.18; p = 0.056). These results confirm that during athletic preparation in volleyball and tennis the specific training is able to develop spatial ability. Besides, boys and girls have similar performance demands and training experience. It appears that this specific training could be responsible for modifying gender differences in performance of spatial ability during adolescence.

School-based athletic programs remain an important context for violence prevention efforts although a better understanding of how gender attitudes and abuse perpetration differ among athletes is needed. We analyzed baseline survey data from the "Coaching Boys into Men" study-a school-based cluster-randomized trial in 16 high schools in Northern California. We describe relationships among gender-inequitable attitudes, sport type, and recent adolescent relationship abuse perpetration among a sample of male athletes (n = 1,648). Gender-inequitable attitudes (adjusted odds ratio (AOR), 3.26; 95% confidence interval (CI), 2.56, 4.15), participation in both high school football and basketball (AOR, 2.08; 95% CI, 1.37, 3.18), and participation in football only (AOR, 1.50; 95% CI, 1.02, 2.22) emerged as independently associated with recent ARA perpetration. Findings warrant targeted violence prevention efforts among male high school athletes that incorporate discussions of gender attitudes and healthy relationships, especially among sports teams at greater risk of adolescent relationship abuse perpetration.

WELLS, ELIZABETH K.; CHIN, ALEXANDRA D.; TACKE, JENNIFER A.; BUNN, JENNIFER A.

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 research aimed to (a) develop a measure of prosocial and antisocial behavior in sport, (b) examine its invariance across sex and sport, and (c) provide evidence for its discriminant and concurrent validity. We conducted two studies. In study 1, team sport athletes (N=1,213) recruited from 103 teams completed questionnaires assessing demographics and prosocial and antisocial behaviors in sport. Factor analyses revealed two factors representing prosocial behavior and two factors representing antisocial behavior. The model had a very good fit to the data and showed configural, metric, and scalar invariance across sex and sport. The final scale consisted of 20 items. In Study 2, team-sport athletes (N=106) completed the scale and measures of empathy and goal orientation. Analyses provided support for the discriminant and concurrent validity of the scale. In conclusion, the new scale can be used to measure prosocial and antisocial behaviors in team sport.

The study aimed to assess whether exposure to ischemic preconditioning (IPC) in a trained population would affect land-based maximal sprinting performance over 30 m. Twenty-five well-trained participants regularly involved in invasion-type team-sport events were recruited to take part in a randomized crossover study design. Participants underwent both an IPC and a placebo treatment involving 3 periods of 5-min occlusion applied unilaterally (3 × 5-min occlusion to each leg) at either 220 mmHg or 50 mmHg, respectively. Each period of occlusion was followed by 5 min of reperfusion. After treatment, 3 maximal sprints over a distance of 30 m were undertaken from a standing start interspersed with 1-min recovery. Split times were recorded at 10, 20, and 30 m. No significant effects of the IPC treatment were observed on sprint speed (P < .05) at any of the split timings; however, a small and negative effect was observed in female participants. Calculated effect sizes of the treatment were found to be trivial (<0.2). Results from the current study suggest there to be no benefit to team-sport players in using IPC as a means of enhancing sprint performance over a distance of 30 m. While IPC has been shown to be beneficial to sprint activities in other sports such as swimming, further research is required to elucidate whether this is the case over distances associated with land-based events in track and field or in events reliant on repeated-sprint ability.

Athlete leadership is defined as an athlete who occupies a formal or informal leadership role within a team and influences team members to achieve a common objective. The area of athlete leadership has been shaped by theories and measurement tools from organizational and sport coaching literatures. The present article describes the conceptual developments within athlete leadership by providing an operational definition of this construct, followed by the theories and measurement tools used to examine athlete leadership. Finally, the present paper describes both qualitative and quantitative research that has emerged over the last decade. The results suggest the importance of this source of leadership within sport teams. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

The purpose of the present study was to examine chiropractic utilization following a sport-related injury among National Team members and other high level Taekwondo athletes. Methods Retrospective surveys were conducted among Canadian male and female Taekwondo athletes (Group A, n = 60) competing in a national tournament and National Taekwondo team athletes (Group B, n = 16) at a training camp. Results A response rate of 46.7% (Group A) and 100% (Group B) was achieved. Twenty five percent (n = 4) of Group A athletes reported never seen a doctor of chiropractic (DC) regarding their injuries. Over 12% (n = 2) reported visiting a DC often, while just over 6% (n = 1) reported that they usually visited the DC following an injury. When injured, over 36% (n = 7) of the National Team members visit their family physician, over 15% (n = 3) visit a chiropractor or physiotherapist and the remaining athletes (n = 6) equally visit osteopaths, massage therapists, or athletic therapist following an injury. Conclusion There is a lack of information surrounding chiropractic utilization in the majority of sports and minimal research published regarding the health care utilization of Taekwondo athletes. Chiropractors, and particularly those with extensive athlete contact, should endeavour to further utilization studies. PMID:18516286

Objectives Few epidemiological studies have focused on the psychological health of high level athletes. This study aimed to identify the principal psychological problems encountered within French high level athletes, and the variations in their prevalence based on sex and the sport practiced. Methods Multivariate analyses were conducted on nationwide data obtained from the athletes' yearly psychological evaluations. Results A representative sample of 13% of the French athlete population was obtained. 17% of athletes have at least one ongoing or recent disorder, generalized anxiety disorder (GAD) being the most prevalent (6%), followed by non-specific eating disorders (4.2%). Overall, 20.2% of women had at least one psychopathology, against 15.1% in men. This female predominance applied to anxiety and eating disorders, depression, sleep problems and self-harming behaviors. The highest rates of GAD appeared in aesthetic sports (16.7% vs. 6.8% in other sports for men and 38.9% vs. 10.3% for women); the lowest prevalence was found in high risk sports athletes (3.0% vs. 3.5%). Eating disorders are most common among women in racing sports (14% vs. 9%), but for men were found mostly in combat sports (7% vs. 4.8%). Discussion This study highlights important differences in psychopathology between male and female athletes, demonstrating that the many sex-based differences reported in the general population apply to elite athletes. While the prevalence of psychological problems is no higher than in the general population, the variations in psychopathology in different sports suggest that specific constraints could influence the development of some disorders.

Fairbairn, Jessica R; Huxel Bliven, Kellie C

2018-02-06

Clinical Scenario: Until recently, injury epidemiology data on elite Paralympic athletes was limited. Current data suggests high rates of shoulder injury in wheelchair athletes. Differences in shoulder injury rates between sports have not been reported in this population. Is the incidence of shoulder injury in elite wheelchair athletes different between sports? Summary of Key Findings: Shoulder injury rates are high in elite wheelchair athletes, particularly in sports such as field events and fencing that require a stable base (eg, trunk, core control) from which to perform. Wheelchair racing requires repetitive motions that contribute to shoulder injuries, but rates are lower than field sports and fencing. Wheelchair curling and sledge hockey have low shoulder injury risk. Clinical Bottom Line: Shoulder injury rates vary based on sport in elite wheelchair athletes. In addition to incorporating shoulder complex specific rehabilitation for overuse shoulder injuries, clinicians should focus on core and trunk stabilization in elite wheelchair athletes competing in sports such as field events and fencing. Strength of Recommendation: Grade C evidence exists that reports shoulder injury rates among elite wheelchair athletes differ base upon sport participation.

To ascertain how talented young British swimmers, gymnasts, tennis and soccer players are introduced to their sport, and to identify how they are encouraged into intensive systematic training. Two hundred and eighty-two elite young athletes (aged 8 to 17 yrs) and their parents were interviewed in their homes to identify how and why they started intensive training. Of the 4 sports studied (soccer, gymnastics, tennis, and swimming), parents of swimmers were more likely introduce their children to the sport (70%), while parents of gymnasts (42%) were the least likely to do so. However, in this sports parents played a lesser role in the transition to intensive training (6% and 5%, respectively). Nearly half the soccer players (47%) became involved in the sport because of their own interest, with the majority making the transition to intensive training because of encouragement by a coach (65%). Self-motivation (27%) and parental influence (57%) brought children into tennis with 25% of the young athletes in the sample autonomously deciding to start intensive training. Children from the lower socio-economic classes were underrepresented, and the total number of 1-parent families (5.3%) was considerably less than current British national norms (16.1%). In Britain, young athletes' involvement in high level sport is heavily dependent on their parents, with sports clubs and coaches playing an important later role. In the present socio-economic and cultural situation, many talented youngsters with less motivated parents will not undertake sport. Talented youngsters from a poorer economic background will be heavily disadvantaged, especially in sports such as tennis.

Higgins, TR, Greene, DA, Baker, MK. Effects of cold water immersion and contrast water therapy for recovery from team sport: a systematic review and meta-analysis. J Strength Cond Res 31(5): 1443-1460, 2017-To enhance recovery from sport, cold water immersion (CWI) and contrast water therapy (CWT) have become common practice within high level team sport. Initially, athletes relied solely on anecdotal support. As there has been an increase in the volume of research into recovery including a number of general reviews, an opportunity existed to narrow the focus specifically examining the use of hydrotherapy for recovery in team sport. A Boolean logic [AND] keyword search of databases was conducted: SPORTDiscus; AMED; CINAHL; MEDLINE. Data were extracted and the standardized mean differences were calculated with 95% confidence interval (CI). The analysis of pooled data was conducted using a random-effect model, with heterogeneity assessed using I. Twenty-three peer reviewed articles (n = 606) met the criteria. Meta-analyses results indicated CWI was beneficial for recovery at 24 hours (countermovement jump: p = 0.05, CI: -0.004 to 0.578; All-out sprint: p = 0.02, -0.056 to 0.801) following team sport. The CWI was beneficial for recovery at 72 hours (fatigue: p = 0.03, CI: 0.061-1.418) and CWT was beneficial for recovery at 48 hours (fatigue: p = 0.04, CI: 0.013-0.942) following team sport. The CWI was beneficial for neuromuscular recovery 24 hours following team sport, whereas CWT was not beneficial for recovery following team sport. In addition, when evaluating accumulated sprinting, CWI was not beneficial for recovery following team sports. In evaluating subjective measures, both CWI (72 hours) and CWT (24 hours) were beneficial for recovery of perceptions of fatigue, following team sport. However neither CWI nor CWT was beneficial for recovery, of perceptions of muscle soreness, following team sport.

Objective The purpose of this meta-analysis was to study the short-term adaptations on sprint and vertical jump (VJ) performance following Complex Training (CT) in team-sports. CT is a resistance training method aimed at developing both strength and power, which has a direct effect on sprint and VJ. It consists on alternating heavy resistance training exercises with plyometric/power ones, set for set, on the same workout. Methods A search of electronic databases up to July 2016 (PubMed-MEDLINE, SPORTDiscus, Web of Knowledge) was conducted. Inclusion criteria: 1) at least one CT intervention group; 2) training protocols ≥4-wks; 3) sample of team-sport players; 4) sprint or VJ as an outcome variable. Effect sizes (ES) of each intervention were calculated and subgroup analyses were performed. Results A total of 9 studies (13 CT groups) met the inclusion criteria. Medium effect sizes (ES) (ES = 0.73) were obtained for pre-post improvements in sprint, and small (ES = 0.41) in VJ, following CT. Experimental-groups presented better post-intervention sprint (ES = 1.01) and VJ (ES = 0.63) performance than control-groups. Sprint large ESs were exhibited in younger athletes (<20 years old; ES = 1.13); longer CT interventions (≥6 weeks; ES = 0.95); conditioning activities with intensities ≤85% 1RM (ES = 0.96) and protocols with frequencies of <3 sessions/week (ES = 0.84). Medium ESs were obtained in Division I players (ES = 0.76); training programs >12 total sessions (ES = 0.74). VJ Large ESs in programs with >12 total sessions (ES = 0.81). Medium ESs obtained for under-Division I individuals (ES = 0.56); protocols with intracomplex rest intervals ≥2 min (ES = 0.55); conditioning activities with intensities ≤85% 1RM (ES = 0.64); basketball/volleyball players (ES = 0.55). Small ESs were found for younger athletes (ES = 0.42); interventions ≥6 weeks (ES = 0.45). Conclusions CT interventions have positive medium effects on sprint performance and small effects on VJ in

Visual- spatial capacity: gender and sport differences in young volleyball and tennis athletes and non-athletes

PubMed Central

2014-01-01

Background In the general population visual-spatial ability is better in males, due to the influence of biological and socio-cultural factors. We know that sport activity improves motor skills. The aim of this work is to determine if these gender differences exist in young athletes. The orientation test described by Terzi and standardized by Cesaroni, used to measure spatial ability, was carried out on 60 volleyball or 60 tennis athletes as well as on 60 non-sporting subjects. Results The data analysis revealed a worse performance for non-athletes in comparison with athletes in both components of test (p < 0.0001; p = 0.04), with no differences between the volleyball and tennis groups. As far as gender comparison is concerned, as expected in the non- sport group the males presented better values (p < 0.001; p = 0.006). However in both sports groups there weren’t any gender differences in either part of the test (p = 0.18; p = 0.056). Conclusions These results confirm that during athletic preparation in volleyball and tennis the specific training is able to develop spatial ability. Besides, boys and girls have similar performance demands and training experience. It appears that this specific training could be responsible for modifying gender differences in performance of spatial ability during adolescence. PMID:24447526

Management of sport-related concussion in young athletes.

Patel, Dilip R; Shivdasani, Vandana; Baker, Robert J

2005-01-01

Sport-related head injuries are a common clinical problem. Most head injuries in young athletes are mild traumatic brain injuries or concussions. The highest number of sport-related concussions has been reported in American football. In addition to the well described physical and psychosocial growth, there is ongoing neurocognitive development of the brain during childhood and through adolescence. This developmental process has direct implications in the assessment and management of head injuries in young athletes. Research on the management and long-term outcome following brain injuries in young athletes is limited. Traditionally, the assessment of concussion has been based on clinical history and physical and neurological examination. Increasingly, neuropsychological testing, especially computerised testing, is providing objective measures for the initial assessment and follow-up of young athletes following brain injuries. Numerous guidelines have been published for grading and return to play criteria following concussion; however, none of these have been prospectively validated by research and none are specifically applicable to children and adolescents.

Background and aims Recently, empirical research has linked obsessive passion to the etiology of exercise addiction, and the conceptual reason behind the fact that the latter is more prevalent in athletes than leisure exercisers has been challenged. The aim of this study was to determine the link between exercise addiction and harmonious passion, obsessive passion, and dedication to sports, in the context of athletic levels. Method A sample comprised of low- and high-level competitive athletes and non-competitive leisure exercisers (n = 313) was examined, in a cross-sectional design, in which participants completed the Spanish validated versions of the Exercise Addiction Inventory (Sicilia, Alías-García, Ferriz, & Moreno-Murcia, 2013) and Passion Scale (Chamarro et al., 2015). Results Obsessive passion and dedication to sports emerged as strong predictors of exercise addiction. Competitive athletes scored higher than leisure exercisers on all measures. Athletes competing at low and high levels only differed in dedication to their sports from each other. Team-sports athletes reported greater harmonious and obsessive passions, and dedication to sports, but not different exercise addictions, than people taking part in individual sports. Conclusions The concept of exercise addiction is not a plain and independent construct and may not reflect a psychological dysfunction in the athletic population. Athletes could interpret exercise addiction screening-items differently from non-athletes. Athletes in team sports report greater passion and dedication than those practicing individual sports.

Platen, Petra

2017-01-01

Objectives To establish the prevalence of back pain in German elite athletes; examine the influence of age, sex, sports discipline and training volume; and compare elite athletes with a physically active control group. Methods A standardized and validated online back pain questionnaire was sent by the German Olympic Sports Confederation to approximately 4,000 German national and international elite athletes, and a control group of 253 physically active but non-elite sports students. Results We received responses from 1,114 elite athletes (46.5% male and 53.1% female, mean age 20.9 years ± 4.8 years, mean height 176.5 ± 11.5 cm, mean weight 71.0 ± 10.3 kg) and 166 physically active sports students (74.7% male and 24.1 female, mean age 21.2 ± 2.0 years, mean height 180.0 ± 8.0 cm, mean weight 74.0 ± 14.5 kg). In elite athletes, the lifetime prevalence of back pain was 88.5%, the 12-month prevalence was 81.1%, the 3-month prevalence was 68.3% and the point prevalence was 49.0%, compared with 80.7%, 69.9%, 59.0% and 42.8%, respectively in the control group. The lifetime, 12-month and 3-month prevalences in elite athletes were significantly higher than in the control group. Regarding the individual sports disciplines, the prevalence of back pain was significantly higher in elite rowers, dancers, fencers, gymnasts, track and field athletes, figure skaters and marksmen, and those who play underwater rugby, water polo, basketball, hockey and ice hockey compared with the control group. The prevalence of back pain was significantly lower in elite triathletes. Conclusions Back pain is a common complaint in German elite athletes. Low back pain seems to be a problem in both elite athletes and physically active controls. A high training volume in elite athletes and a low training volume in physically active individuals might increase prevalence rates. Our findings indicate the necessity for specific prevention programs, especially in high-risk sports. Further research

Participation in High-Impact Sports Predicts Bone Mineral Density in Senior Olympic Athletes

PubMed Central

Leigey, Daniel; Irrgang, James; Francis, Kimberly; Cohen, Peter; Wright, Vonda

2009-01-01

Background: Loss of bone mineral density (BMD) and resultant fractures increase with age in both sexes. Participation in resistance or high-impact sports is a known contributor to bone health in young athletes; however, little is known about the effect of participation in impact sports on bone density as people age. Hypothesis: To test the hypothesis that high-impact sport participation will predict BMD in senior athletes, this study evaluated 560 athletes during the 2005 National Senior Games (the Senior Olympics). Study Design: Cross-sectional methods. The athletes completed a detailed health history questionnaire and underwent calcaneal quantitative ultrasound to measure BMD. Athletes were classified as participating in high impact sports (basketball, road race [running], track and field, triathalon, and volleyball) or non-high-impact sports. Stepwise linear regression was used to determine the influence of high-impact sports on BMD. Results: On average, participants were 65.9 years old (range, 50 to 93). There were 298 women (53.2%) and 289 men (51.6%) who participated in high-impact sports. Average body mass index was 25.6 ± 3.9. The quantitative ultrasound-generated T scores, a quantitative measure of BMD, averaged 0.4 ± 1.3 and −0.1 ± 1.4 for the high-impact and non-high-impact groups, respectively. After age, sex, obesity, and use of osteoporosis medication were controlled, participation in high-impact sports was a significant predictor of BMD (R2 change 3.2%, P < .001). Conclusions: This study represents the largest sample of BMD data in senior athletes to date. Senior participation in high-impact sports positively influenced bone health, even in the oldest athletes. Clinical Relevance: These data imply that high-impact exercise is a vital tool to maintain healthy BMD with active aging. PMID:23015914

Sport-specific functional movement can simulate aspects of neuromuscular fatigue occurring in team sports.

Fatigue protocols have been used over the years to examine muscular exhaustion. As an alternative to approaches in laboratory settings, functional agility protocols claiming to mimic the multifaceted loads of athletic activity have been proposed. This study aimed to examine the effects of a functional agility short-term fatigue protocol (FAST-FP) on neuromuscular function. Twenty-eight healthy sports students (15 males, aged 24.3 ± 2.4 years) completed the FAST-FP, which consists of four components: three counter-movement jumps (90% of individual maximum), a 20-s bout of step-ups, three bodyweight squats and an agility run. Tasks were repeated until the participants no longer achieved the required jump height in two consecutive sets. Outcomes (pre-post) encompassed subjective exhaustion (visual analogue scale [VAS]), maximum isometric voluntary force of the knee extensors (MIVF), reactive strength index (RSI), mean power frequency (MPF, measured using surface electromyography) and maximum knee range of motion (ROM). Post-intervention, VAS (+54 mm) increased significantly, while MIVF (-6.1%), RSI (-10.7%) and MPF (-4.1%) were reduced (p < 0.05). No changes were observed for ROM (p > 0.05). The FAST-FP induces small-to-moderate impairments in neuromuscular function and considerable self-perceived fatigue. Current evidence on exhaustion developing in team sports suggests that this magnitude of fatigue is similar. The protocol might thus be valuable in the evaluation of treatments counteracting post-match fatigue in team sports.

Sports teams as superorganisms: implications of sociobiological models of behaviour for research and practice in team sports performance analysis.

PubMed

Duarte, Ricardo; Araújo, Duarte; Correia, Vanda; Davids, Keith

2012-08-01

Significant criticisms have emerged on the way that collective behaviours in team sports have been traditionally evaluated. A major recommendation has been for future research and practice to focus on the interpersonal relationships developed between team players during performance. Most research has typically investigated team game performance in subunits (attack or defence), rather than considering the interactions of performers within the whole team. In this paper, we offer the view that team performance analysis could benefit from the adoption of biological models used to explain how repeated interactions between grouping individuals scale to emergent social collective behaviours. We highlight the advantages of conceptualizing sports teams as functional integrated 'super-organisms' and discuss innovative measurement tools, which might be used to capture the superorganismic properties of sports teams. These tools are suitable for revealing the idiosyncratic collective behaviours underlying the cooperative and competitive tendencies of different sports teams, particularly their coordination of labour and the most frequent channels of communication and patterns of interaction between team players. The principles and tools presented here can serve as the basis for novel approaches and applications of performance analysis devoted to understanding sports teams as cohesive, functioning, high-order organisms exhibiting their own peculiar behavioural patterns.

Dental trauma in sports is the major linking channel between sports and dentistry. Sports dentistry is the prevention of oral/facial athletic injuries and related oral diseases and manifestations. In children, sports activities were found to be responsible for 13% of overall oral trauma. It is emphasized that there is a great need for “Team Dentist” from high schools to professional teams. In this review, we discuss the relationship between sports and dentistry, and the importance of educating parents, teachers, and children in prevention of injuries related to the sports.

Identification of modifying factors that influence the development of post-concussion syndrome (PCS) following sport-related concussion (SRC) has drawn considerable interest. In this pilot study, we investigate the effect of team vs. individual sport participation on the development of PCS in a sample of 136 high school and college student-athletes. Controlling for several confounding variables, we employed a binary logistic regression and chi-squared test. Results of this pilot study indicate that participation in team versus individual sport is not a significant factor in the development of PCS. The identification of other forms of protective mechanisms is discussed.

Pre-participation and follow-up screening of athletes for endurance sport.

Physical activity increases life expectancy and sport is a priori not harmful. Exhausted sporting activity (e.g. endurance running, triathlon, cycling or competitive sport) can lead under individual conditions to negative cardiac remodelling (pathological enlargement/function of cardiac cavities/structures) or in worst case to cardiac arrhythmias and sudden cardiac death (SCD). This individually disposition can be genetically determined or behaviourally/environmentally acquired. Overall competitive young male athletes suffer five-fold higher than non-competitive athletes from sudden death and athletes aged over 30 bear a potential for arrhythmias, atrial fibrillation or a 20-fold higher possibility for SCD as female athletes. Patients with diabetes, coronary disease, obesity or hypertension require different special managements. Screening of cardiorespiratory health for sport activities has a lot of faces. Basically there is a need for indicated examinations or possible preventive measures inside or outside of pre-competition screening. The costs of screening compared to expenditure of whole effort for sporting activities are acceptable or even negligible, but of course dependent on national/regional settings. The various causes and possibilities of screening will be discussed in this article as basic suggestion for an open discussion beyond national borders and settings.

In the United States (US), an estimated 300,000 sports-related concussions occur annually. Among individuals 15 to 24 years of age, sports are second only to motor vehicle crashes as the leading cause of concussions. To investigate the epidemiology of concussions in high school athletes by comparing rates and patterns of concussion among 20 sports. Descriptive epidemiology study. Using an Internet-based data collection tool, RIO, certified athletic trainers from a large, nationally disperse sample of US high schools reported athlete exposure and injury data for 20 sports during the 2008-2010 academic years. During the study period, 1936 concussions were reported during 7,780,064 athlete-exposures (AEs) for an overall injury rate of 2.5 per 10,000 AEs. The injury rate was higher in competition (6.4) than practice (1.1) (rate ratio [RR], 5.7; 95% confidence interval [CI], 5.2-6.3). The majority of concussions resulted from participation in football (47.1%, n = 912), followed by girls' soccer (8.2%, n = 159), boys' wrestling (5.8%, n = 112), and girls' basketball (5.5%, n = 107). Football had the highest concussion rate (6.4), followed by boys' ice hockey (5.4) and boys' lacrosse (4.0). Concussions represented a greater proportion of total injuries among boys' ice hockey (22.2%) than all other sports studied (13.0%) (injury proportion ratio [IPR], 1.7; 95% CI, 1.4-2.1; P < .01). In gender-comparable sports, girls had a higher concussion rate (1.7) than boys (1.0) (RR, 1.7; 95% CI, 1.4-2.0). The most common mechanisms of injury were player-player contact (70.3%) and player-playing surface contact (17.2%). In more than 40% of athletes in sports other than girls' swimming and girls' track, concussion symptoms resolved in 3 days or less. Athletes most commonly returned to play in 1 to 3 weeks (55.3%), with 22.8% returning in less than 1 week and 2.0% returning in less than 1 day. Although interest in sports-related concussions is usually focused on full-contact sports

The incidence of anterior cruciate ligament (ACL) injuries among dancers is much lower than among team sport athletes, and no clear disparity between sexes has been reported in the dance population. Although numerous studies have observed differences in landing biomechanics of the lower extremity between male and female team sport athletes, there is currently little research examining the landing biomechanics of male and female dancers and none comparing athletes to dancers. Comparing the landing biomechanics within these populations may help explain the lower overall ACL injury rates and lack of sex disparity. The purpose was to compare the effects of sex and group (dancer vs team sport athlete) on single-legged drop-landing biomechanics. The primary hypothesis was that female dancers would perform a drop-landing task without demonstrating typical sex-related risk factors associated with ACL injuries. A secondary hypothesis was that female team sport athletes would display typical ACL risk factors during the same task. Controlled laboratory study. Kinematics and kinetics were recorded as 40 elite modern and ballet dancers (20 men and 20 women) and 40 team sport athletes (20 men and 20 women) performed single-legged drop landings from a 30-cm platform. Joint kinematics and kinetics were compared between groups and sexes with a group-by-sex multivariate analysis of variance (MANOVA) followed by pairwise t tests. Dancers of both sexes and male team sport athletes landed similarly in terms of frontal-plane knee alignment, whereas female team sport athletes landed with a significantly greater peak knee valgus (P = .007). Female dancers were found to have a lower hip adduction torque than those of the other 3 groups (P = .003). Dancers (male and female) exhibited a lower trunk side flexion (P = .002) and lower trunk forward flexion (P = .032) compared with team sport athletes. In executing a 30-cm drop landing, female team sport athletes displayed a greater knee valgus

2017-12-01

Canadian adolescents have some of the highest rates of substance use in the world. The etiology of this phenomenon has not been fully explored, and one possible contextual determinant is involvement in sport activities that foster risk-taking behaviors through physical and social mechanisms. Using the 2013-14 Health Behaviour in School Aged Children (HBSC) study we therefore examined this hypothesis in a contemporary national sample of Canadian adolescents. The strength and direction of the relationship between sport and substance use varied by gender and substance, with team sport participation associated with increased binge drinking (RR 1.33 [95% CI 1.13-1.56] for boys, RR 1.21 [1.06-1.38] for girls) and use of smokeless tobacco (RR 1.68 [1.34-2.10] for boys, RR 1.32 [1.01-1.72] for girls), but with lower prevalence levels of cannabis use (RR 0.73 [95% CI 0.61-0.88]) and cigarette smoking (RR 0.79 [95% CI 0.70-0.89]) in girls alone. We also compared team sport athletes with high social involvement (sports team as primary peer group) and physical involvement (higher number of days/week physically active) to those with low involvement. For boys, the combination of high physical and high social involvement was associated with the highest risk, while high social involvement alone was associated with the greatest risk for girls. While team sport participation confers only a small increased risk for substance use, the prevalence of sport participation results in a large population impact. Given this fact, interventions such as education for parents and coaches and policies encouraging engagement in a variety of extracurricular activities should be explored.

The primary objective was to calculate the rate of return to sport (RTS) following anterior cruciate ligament (ACL) reconstruction in elite athletes. Secondary objectives were to estimate the time taken to RTS, calculate rates of ACL graft rupture, evaluate postsurgical athletic performance and identify determinants of RTS. Pooled RTS and graft rupture rates were calculated using random effects proportion meta-analysis. Time to RTS, performance data and determinants of RTS were synthesised descriptively. MEDLINE, EMBASE, AMED, CINAHL, AMI, PEDro, SPORTDiscus and The Cochrane Library were searched from inception to 19 January 2016. Hand searching of 10 sports medicine journals and reference checking were also performed. Studies were included if they reported the ratio of elite athletes who returned to their preinjury level of sport following ACL reconstruction. Twenty-four studies were included. The pooled RTS rate was 83% (95% CI 77% to 88%). The mean time to RTS ranged from 6 to 13 months. The pooled graft rupture rate was 5.2% (95% CI 2.8% to 8.3%). Six out of nine studies that included a noninjured control group found no significant deterioration in athletic performance following ACL reconstruction. Indicators of greater athletic skill or value to the team were associated with RTS. Eighty-three per cent of elite athletes returned to sport following ACL reconstruction, while 5.2% sustained a graft rupture. Most athletes who returned to sport performed comparably with matched, uninjured controls. This information may assist in guiding expectations of athletes and clinicians following ACL reconstruction. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Summary Purpose: in the last two decades, several evidences have been provided to support the relationship between single nucleotide polymorphisms and the susceptibility to develop injuries participating in sport and performance related to sports activity. We report up-to-date review of the genetics factors involved in tendon injuries and athletic performance. Methods: we searched PubMed using the terms “sports injuries”, “athletic performance” and “genetics” over the period 1990 to the present day. We also included non-English journals. Results: most of the currently established or putative tendinopathy susceptibility loci have been analyzed by candidate gene studies. The genes currently associated with tendon injuries include gene encoding for collagen, matrix metallopeptidase, tenascin and growth factors. Several genes have been related to the physical performance phenotypes affecting endurance capacity and muscle performance. The most studied include ACE and ACTN3 genes. Conclusions: genetics determines the response of an individual to the surrounding environment. Recently, some of the individual genetic variations contributing to the athletic performance and the onset of musculoskeletal injuries, particularly in tendon and ligament tissues, have been identified. However, the identification of the genetic background related to susceptibility to injuries and physical performance of the athletes is challenging yet and further studies must be performed to establish the specific role of each gene and the potential effect of the interaction of these.

Past research has linked physical activity and sports participation with improved mental and social well-being, including reduced risk of depression and suicidality. In this study we examined relationships among several dimensions of athletic involvement (team sport participation, individual sport participation, athlete identity, and jock identity), gender, and depression and suicidal behavior in a sample of 791 undergraduate students. Both participation in a team sport and athlete identity were associated with lower depression scores. Athlete identity was also associated with lower odds of a past-year suicide attempt, whereas jock identity was associated with elevated odds of a suicide attempt. The findings are discussed in light of the relationship between mental well-being and a larger constellation of health-risk behaviors linked to a “toxic jock” identity. PMID:20661467

Anecdotally many athletes report worse sleep in the nights prior to important competitions. Despite sleep being acknowledged as an important factor for optimal athletic performance and overall health, little is understood about athlete sleep around competition. The aims of this study were to identify sleep complaints of athletes prior to competitions and determine whether complaints were confined to competition periods. Cross-sectional study. A sample of 283 elite Australian athletes (129 male, 157 female, age 24±5 y) completed two questionnaires; Competitive Sport and Sleep questionnaire and the Pittsburgh Sleep Quality Index. 64.0% of athletes indicated worse sleep on at least one occasion in the nights prior to an important competition over the past 12 months. The main sleep problem specified by athletes was problems falling asleep (82.1%) with the main reasons responsible for poor sleep indicated as thoughts about the competition (83.5%) and nervousness (43.8%). Overall 59.1% of team sport athletes reported having no strategy to overcome poor sleep compared with individual athletes (32.7%, p=0.002) who utilised relaxation and reading as strategies. Individual sport athletes had increased likelihood of poor sleep as they aged. The poor sleep reported by athletes prior to competition was situational rather than a global sleep problem. Poor sleep is common prior to major competitions in Australian athletes, yet most athletes are unaware of strategies to overcome the poor sleep experienced. It is essential coaches and scientists monitor and educate both individual and team sport athletes to facilitate sleep prior to important competitions. Copyright © 2014 Sports Medicine Australia.

Sports hernia: the experience of Baylor University Medical Center at Dallas

PubMed Central

2011-01-01

Groin injuries in high-performance athletes are common, occurring in 5% to 28% of athletes. Athletic pubalgia syndrome, or so-called sports hernia, is one such injury that can be debilitating and sport ending in some athletes. It is a clinical diagnosis of chronic, painful musculotendinous injury to the medial inguinal floor occurring with athletic activity. Over the past 12 years, we have operated on >100 patients with this injury at Baylor University Medical Center at Dallas. These patients have included professional athletes, collegiate athletes, competitive recreational athletes, and the occasional “weekend warrior.” The repair used is an open technique using a lightweight polypropylene mesh. Patient selection is important, as is collaboration with other experienced and engaged sports health care professionals, including team trainers, physical therapists, team physicians, and sports medicine and orthopedic surgeons. Of the athletes who underwent surgery, 98% have returned to competition. After a minimum of 6 weeks for recovery and rehabilitation, they have usually returned to competition within 3 months.

Long term neurological impairments due to repetitive head trauma are a growing concern for collision sport athletes. American Football has the highest rate of reported concussions among male high school athletes, a position held by soccer for female high school athletes. Recent research has shown that subconcussive events experienced by collision sport athletes can be a further significant source of accrued damage. Collision sport athletes experience hundreds of subconcussive events in a single season, and these largely go uninvestigated as they produce no overt clinical symptoms. Continued participation by these seemingly uninjured athletes is hypothesized to increase susceptibility to diagnoseable brain injury. This study paired magnetic resonance spectroscopy with head impact monitoring to quantify the relationship between metabolic changes and head acceleration event characteristics in high school-aged male football and female soccer collision sport athletes. During the period of exposure to subconcussive events, asymptomatic male (football) collision sport athletes exhibited statistically significant changes in concentrations of glutamate+glutamine (Glx) and total choline containing compounds (tCho) in dorsolateral prefrontal cortex, and female (soccer) collision sport athletes exhibited changes in glutamate+glutamine (Glx) in primary motor cortex. Neurometabolic alterations observed in football athletes during the second half of the season were found to be significantly associated with the average acceleration per head acceleration events, being best predicted by the accumulation of events exceeding 50 g. These marked deviations in neurometabolism, in the absence of overt symptoms, raise concern about the neural health of adolescent collision-sport athletes and suggest limiting exposure to head acceleration events may help to ameliorate the risk of subsequent cognitive impairment.

The purpose was to examine cigarette smoking, use of snus, alcohol, and performance-enhancing illicit drugs among adolescent elite athletes and controls, and possible gender and sport group differences. First-year students at 16 Norwegian Elite Sport High Schools (n = 677) and two randomly selected high schools (controls, n = 421) were invited to participate. Totally, 602 athletes (89%) and 354 (84%) controls completed the questionnaire. More controls than athletes were smoking, using snus, and drinking alcohol. Competing in team sports was associated with use of snus [odds ratio = 2.8, 95% confidence interval (CI) 1.6 to 4.7] and a similar percentage of male and female handball (22.2% vs 18.8%) and soccer players (15.7% vs 15.0%) reported using snus. For controls, not participating in organized sport was a predictor for smoking (odds ratio = 4.9, 95% CI 2.2 to 10.9). Female athletes were more prone to drink alcohol than males (46.3% vs 31.0%, P < 0.001). Only, 1.2% athletes and 2.8% controls reported use of performance-enhancing illicit drugs. In conclusion, use of legal drugs is less common among athletes, but this relationship depends on type of sport and competition level. The association between team sports and use of snus suggests that sport subcultures play a role. © 2012 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Participation in sport has many physical, psychological and social benefits for the child athlete. A growing body of evidence indicates, however, that sport participation may have inherent threats for the child’s well-being. The subject of safeguarding children in sport has seen an increase in scientific study in recent years. In particular, there is increasing emphasis on identifying who is involved in abuse, the context of where it occurs and the identification of the various forms of abuse that take place in the sporting domain. Safeguarding principles developed by the International Safeguarding Children in Sport Founders Group are presented along with 8 underlying pillars which underpin the successful adoption and implementation of safeguarding strategies. This safeguarding model is designed to assist sport organisations in the creation of a safe sporting environment to ensure that the child athlete can flourish and reach their athletic potential through an enjoyable experience. The aim of this narrative review is to (1) present a summary of the scientific literature on the threats to children in sport; (2) introduce a framework to categorise these threats; (3) identify research gaps in the field and (4) provide safeguarding recommendations for sport organisations.

Ethics in sports medicine.

2007-05-01

Physicians have struggled with the medical ramifications of athletic competition since ancient Greece, where rational medicine and organized athletics originated. Historically, the relationship between sport and medicine was adversarial because of conflicts between health and sport. However, modern sports medicine has emerged with the goal of improving performance and preventing injury, and the concept of the "team physician" has become an integral part of athletic culture. With this distinction come unique ethical challenges because the customary ethical norms for most forms of clinical practice, such as confidentiality and patient autonomy, cannot be translated easily into sports medicine. The particular areas of medical ethics that present unique challenges in sports medicine are informed consent, third parties, advertising, confidentiality, drug use, and innovative technology. Unfortunately, there is no widely accepted code of sports medicine ethics that adequately addresses these issues.

A mouth protector must be easy to fabricate, comfortable, able to accommodate the needs of an individual's dentition, durable, easily held in place, and able to provide adequate protection to the teeth, jaws, and cranial structures. The thermoplastic mouth protector is recommended if it is to be placed or formed by the athlete; however, supervision of the fitting procedure by a dentist is recommended. The most desirable protector, however, is the custom-made mouth protector fabricated by a dentist from a thermoplastic material. With the custom-made protector, the dentist can optimize fit, comfort, and speech as well as tend to any control of form to the special dental requirements of the athlete. Thousands of football players have avoided oral injuries by wearing mouth protectors and faceguards. In other sports, dental safety still needs to be improved. National athletic organizations should be urged to require players to wear adequate mouth protectors. Dentists, health and physical education professionals, and other concerned persons should tell all athletes, patients, and parents, why mouth protectors are necessary and what types of protectors effectively reduce or minimize the incidence of injury. All organized sports teams should have their own team dentists to help ensure that players maintain the best possible oral health. If these actions are taken, fewer athletes will suffer the pain, inconvenience, and expense of unnecessary and frequently disfiguring oral injuries.

OBJECTIVE: To evaluate the incidence of sports injuries in college athletes from the same institution from 1993 to 2013. METHODS: Athletes from 13 modalities were interviewed about the presence and type of injury, type of treatment and time of withdrawal, based on the questionnaire "Injury Surveillance System" (ISS). Data were analyzed with graphs and tables of injury prevalence by gender, age, site of injury and modality. We also analyzed the average time of withdrawal of athletes, returning to sports practice and new lesions. RESULTS: It was observed that 49.91% of the athletes showed some type of injury, with similar incidence between genders; the most frequent injuries were the anterior cruciate ligament (ACL) and the ankle sprain; the average withdrawal time was 11 weeks. ACL was the injury with greater impact on college sports career, especially given the time of withdrawal. CONCLUSION: The most frequent injury, ACL, occurred most frequently in indoor sports such as handball and volleyball and had the highest number of cases treated with surgery and a longer average withdrawal time. More studies are needed to create a larger database in order to schedule preventive measures for amateur athletes. Level IV of Evidence, Epidemiological Study. PMID:25538479

What do athletes drink during competitive sporting activities?

PubMed

Garth, Alison K; Burke, Louise M

2013-07-01

Although expert groups have developed guidelines for fluid intake during sports, there is debate about their real-world application. We reviewed the literature on self-selected hydration strategies during sporting competitions to determine what is apparently practical and valued by athletes. We found few studies of drinking practices involving elite or highly competitive athletes, even in popular sports. The available literature revealed wide variability in fluid intake and sweat losses across and within different events with varied strategies to allow fluid intake. Typical drinking practices appear to limit body mass (BM) losses to ~2 % in non-elite competitors. There are events, however, in which mean losses are greater, particularly among elite competitors and in hot weather, and evidence that individual participants fail to meet current guidelines by gaining BM or losing >2 % BM over the competition activity. Substantial (>5 %) BM loss is noted in the few studies of elite competitors in endurance and ultra-endurance events; while this may be consistent with winning outcomes, such observations cannot judge whether performance was optimal for that individual. A complex array of factors influence opportunities to drink during continuous competitive activities, many of which are outside the athlete's control: these include event rules and tactics, regulated availability of fluid, need to maintain optimal technique or speed, and gastrointestinal comfort. Therefore, it is questionable, particularly for top competitors, whether drinking can be truly ad libitum (defined as "whenever and in whatever volumes chosen by the athlete"). While there are variable relationships between fluid intake, fluid balance across races, and finishing times, in many situations it appears that top athletes take calculated risks in emphasizing the costs of drinking against the benefits. However, some non-elite competitors may need to be mindful of the disadvantages of drinking beyond

The aim of this study was to examine the differences in psychosocial and motivational variables between persistent and dropout youth athletes and between groups with different years in training. Team and individual youth athletes completed questionnaires measuring autonomy support from parents and coaches, peer motivational climate, basic psychological needs satisfaction, and sport motivation. The results showed that athletes who dropped out perceived significantly less competence, relatedness, and autonomy need satisfaction, and they perceived less autonomy support from parents and were less intrinsically motivated than persistent athletes. Youth athletes with up to one year in training reported significantly lower effort and intra-team conflict with peers, relatedness need satisfaction, and external motivation than athletes with 1 to 3 years and >3 years in training. Findings extend knowledge of the psychosocial determinants of sport continuation behaviour among young athletes.

Physicians working in the world of competitive sports face unique ethical challenges, many of which center around conflicts of interest. Team-employed physicians have obligations to act in the club's best interest while caring for the individual athlete. As such, they must balance issues like protecting versus sharing health information, as well as issues regarding autonomous informed consent versus paternalistic decision making in determining whether an athlete may compete safely. Moreover, the physician has to deal with an athlete's decisions about performance enhancement and return to play, pursuit of which may not be in the athlete's long-term best interests but may benefit the athlete and team in the short term. These difficult tasks are complicated by the lack of evidence-based standards in a field influenced by the lure of financial gains for multiple parties involved. In this article, we review ethical issues in sports medicine with specific attention paid to American professional football.

Purpose To investigate the relationship between the classification systems used in wheelchair sports and cardiovascular function in Paralympic athletes with spinal cord injury (SCI). Methods 26 wheelchair rugby (C3-C8) and 14 wheelchair basketball (T3-L1) were assessed for their International Wheelchair Rugby and Basketball Federation sports classification. Next, athletes were assessed for resting and reflex cardiovascular and autonomic function via the change (delta) in systolic blood pressure (SBP) and heart rate (HR) in response to sit-up, and sympathetic skin responses (SSRs), respectively. Results There were no differences in supine, seated, or delta SBP and HR between different sport classes in rugby or basketball (all p > 0.23). Athletes with autonomically complete injuries (SSR score 0-1) exhibited a lower supine SBP, seated SBP and delta SBP compared to those with autonomically incomplete injuries (SSR score >1; all p < 0.010), independent of sport played. There was no association between self-report OH and measured OH (χ 2  =   1.63, p = 0.20). Conclusion We provide definitive evidence that sports specific classification is not related to the degree of remaining autonomic cardiovascular control in Paralympic athletes with SCI. We suggest that testing for remaining autonomic function, which is closely related to the degree of cardiovascular control, should be incorporated into sporting classification. Implications for Rehabilitation Spinal cord injury is a debilitating condition that affects the function of almost every physiological system. It is becoming increasingly apparent that spinal cord injury induced changes in autonomic and cardiovascular function are important determinants of sports performance in athletes with spinal cord injury. This study shows that the current sports classification systems used in wheelchair rugby and basketball do not accurately reflect autonomic and cardiovascular function and thus are placing some

Background The aim of the study was to evaluate differences in body image across different types of sports in highly trained female athletes. Methods 242 female individuals, aged 13–30 years (M = 20.0, SD = 4.5), representing aesthetic sports (n = 56) and nonaesthetic sports (n = 186), were recruited from different sports clubs in Poland. Body image, BMI, age, the level of competition attained, and the training background of participants were recorded. Results One-way ANOVA showed differences in the body image of athletes engaged in different types of sport (F(11,230) = 4.10, p < 0.001, and η2 = 0.16). The model predicting the body image of female athletes was significant (F(5,236) = 10.40, p < 0.001); the adjusted R2 = 0.163. Type of sport explained 7.1% (β = –0.263, p < 0.001), age explained 4.5% (β = 0.341, p < 0.001), BMI explained 3.6% (β = –0.230, p < 0.001), and level of competition explained 0.9% (β = 0.153, p < 0.05) of variance in body image. Conclusions The findings provide vital new knowledge which can be used by researchers and practitioners in designing educational programs on weight-related behaviors in female athletes. Such programs should be implemented especially in young female athletes participating in high-level sporting activities at an early stage. PMID:29662894

Kellmann, M

2010-10-01

In sports, the importance of optimizing the recovery-stress state is critical. Effective recovery from intense training loads often faced by elite athletes can often determine sporting success or failure. In recent decades, athletes, coaches, and sport scientists have been keen to find creative, new methods for improving the quality and quantity of training for athletes. These efforts have consistently faced barriers, including overtraining, fatigue, injury, illness, and burnout. Physiological and psychological limits dictate a need for research that addresses the avoidance of overtraining, maximizes recovery, and successfully negotiates the fine line between high and excessive training loads. Monitoring instruments like the Recovery-Stress Questionnaire for Athletes can assist with this research by providing a tool to assess their perceived state of recovery. This article will highlight the importance of recovery for elite athletes and provide an overview of monitoring instruments. © 2010 John Wiley & Sons A/S.

There are many reasons why individuals are motivated to participate in sports. Less attention, however, is given for studying motivation and athlete development in adapted sport. The purpose of this study was to identify the motivations, facilitators, and barriers to sports participation of elite athletes with a physical disability. Participants (N = 23, 17 males, six females, mean age: 24.3 years) were recruited through online listservs, e-mails, and snowball sampling. A semistructured interview guide was employed. Analysis was conducted and grounded in self-determination theory and literature surrounding barriers and facilitators of sports participation. Through coding by multiple researchers, six themes emerged. Themes indicated that athletes attributed participation to constructs of self-determination theory as well as overcoming specific barriers such as cost, time constraints, and lack of opportunity. Among facilitators to their athletic development, there were empowerment and advocacy, increased health, college scholarships, and achieving performance-related goals.

Athletic Hip Injuries.

2017-04-01

Historically, athletic hip injuries have garnered little attention; however, these injuries account for approximately 6% of all sports injuries and their prevalence is increasing. At times, the diagnosis and management of hip injuries can be challenging and elusive for the team physician. Hip injuries are seen in high-level athletes who participate in cutting and pivoting sports that require rapid acceleration and deceleration. Described previously as the "sports hip triad," these injuries consist of adductor strains, osteitis pubis, athletic pubalgia, or core muscle injury, often with underlying range-of-motion limitations secondary to femoroacetabular impingement. These disorders can happen in isolation but frequently occur in combination. To add to the diagnostic challenge, numerous intra-articular disorders and extra-articular soft-tissue restraints about the hip can serve as pain generators, in addition to referred pain from the lumbar spine, bowel, bladder, and reproductive organs. Athletic hip conditions can be debilitating and often require a timely diagnosis to provide appropriate intervention.

The Association of Sport Specialization and Training Volume With Injury History in Youth Athletes.

Recommendations exist to encourage safe youth participation in sport. These recommendations include not specializing in 1 sport, limiting participation to less than 8 months per year, and limiting participation to fewer hours per week than a child's age. However, limited evidence exists to support or refute these recommendations. High levels of specialization will be associated with a history of injuries and especially overuse injuries, independent of age, sex, or weekly sport training hours. Athletes who exceed current sport volume recommendations will be more likely to have a history of injuries and overuse injuries. Case-control study; Level of evidence, 3. Youth athletes (n = 2011; 989 female and 1022 male; 12-18 years of age) completed a questionnaire regarding their specialization status, yearly and weekly sport participation volume, and injury history. Specialization was classified as low, moderate, or high using a previously utilized 3-point scale. Athletes were classified into groups based on either meeting or exceeding current volume recommendations (months per year and hours per week). Odds ratios (ORs) and 95% CIs were calculated to investigate associations of specialization and volume of participation with a history of sport-related injuries in the past year ( P ≤ .05). Highly specialized athletes were more likely to report a previous injury of any kind ( P < .001; OR, 1.59; 95% CI, 1.26-2.02) or an overuse injury ( P = .011; OR, 1.45; 95% CI, 1.07-1.99) in the previous year compared with athletes in the low specialization group. Athletes who played their primary sport more than 8 months of the year were more likely to report an upper extremity overuse injury ( P = .04; OR, 1.68; 95% CI, 1.06-2.80) or a lower extremity overuse injury ( P = .001; OR, 1.66; 95% CI, 1.22-2.30).

Context: There is increased growth in sports participation across the globe. Sports specialization patterns, which include year-round training, participation on multiple teams of the same sport, and focused participation in a single sport at a young age, are at high levels. The need for this type of early specialized training in young athletes is currently under debate. Evidence Acquisition: Nonsystematic review. Study Design: Clinical review. Level of Evidence: Level 4. Conclusion: Sports specialization is defined as year-round training (greater than 8 months per year), choosing a single main sport, and/or quitting all other sports to focus on 1 sport. Specialized training in young athletes has risks of injury and burnout, while the degree of specialization is positively correlated with increased serious overuse injury risk. Risk factors for injury in young athletes who specialize in a single sport include year-round single-sport training, participation in more competition, decreased age-appropriate play, and involvement in individual sports that require the early development of technical skills. Adults involved in instruction of youth sports may also put young athletes at risk for injury by encouraging increased intensity in organized practices and competition rather than self-directed unstructured free play.

2009-01-01

Spectators of the Olympic Games can enjoy a wide variety of sports, including strength, team, timed, endurance, and artistic sports. In the Olympic program, there are two synchronized events: synchronized diving and synchronized swimming. The precision of the synchronization of the athlete's movements and skills is an added feature of entertainment. Synchronized athletes have additional training requirements to perfect the synchronization of their skills. The physical demands on the athlete from the repetition of training required for the perfection of synchronization result in injuries unique to these sports. Although both traumatic and overuse injuries occur, overuse injuries are more common. As these disciplines are artistic, judged sports, these athletes also are susceptible to eating disorders and the female athlete triad. This article reviews the training regimen of these athletes and outlines the injuries and health concerns that are common in the synchronized sports.

Many sports incorporate training at altitude as a key component of their athlete training plan. Furthermore, many sports are required to compete at high altitude venues. Exercise at high altitude provides unique challenges to the athlete and to the sport medicine clinician working with these athletes. These challenges include altitude illness, alterations in training intensity and performance, nutritional and hydration difficulties, and challenges related to the austerity of the environment.

Rotator cuff tears in young overhead sports athletes are rare. The pathomechanism causing rotator cuff tears in young overhead athletes is different from that in aged patients. The purpose of this study was to investigate rotator cuff tear characteristics in young overhead sports athletes to reveal the pathomechanism causing these injuries. This study included 25 overhead sports athletes less than 30 years old with atraumatic rotator cuff tears necessitating repair. Rotator cuff tear characteristics were evaluated intraoperatively, including rotator cuff tear shape and injured rotator cuff tendon. Clinical outcome measures were assessed before surgery and at the final follow-up. In this study, 22 patients reported minimal to no shoulder pain and returned to sports without significant complaints at last follow-up. The isolated infraspinatus tendon was most often injured; the incidence rate of the tear at this site was 32% (8 cases). In the deceleration phase of overhead motion, the eccentric contraction force of the ISP (infraspinatus) tendon peaks and the increased load leads to injury at the ISP tendon. The pathomechanism of rotator cuff injuries in young overhead athletes might be not only internal or subacromial impingement, but also these mechanisms. PMID:28702502

To determine if sport specialization increases the risk of anterior knee pain in adolescent female athletes. Retrospective cohort epidemiology study. Female basketball, soccer, and volleyball players (N = 546) were recruited from a single county public school district in Kentucky consisting of 5 middle schools and 4 high schools. A total of 357 multisport and 189 single-sport (66 basketball, 57 soccer, and 66 volleyball) athlete subjects were included due to their diagnosis of patellofemoral pain (PFP) on physical exam. Testing consisted of a standardized history and physician-administered physical examination to determine the presence of PFP. This study compared self-reported multisport athletes with sport-specialized athletes participating in only 1 sport. The sports-participation data were normalized by sport season, with each sport accounting for 1 season of exposure. Incidence rate ratios and 95% confidence intervals (CI) were calculated and used to determine significant differences between athletes who specialized in sport in early youth and multisport athletes. Specialization in a single sport increased the relative risk of PFP incidence 1.5-fold (95% CI 1.0-2.2, P = .038) for cumulative PFP diagnoses. Specific diagnoses such as Sinding Larsen Johansson/ patellar tendinopathy (95% CI 1.5-10.1, P = .005) and Osgood Schlatter disease (95% CI 1.5-10.1, P = .005) demonstrated a 4-fold greater relative risk in single-sport compared with multisport athletes. Incidence of other specific PFP diagnoses such as fat pad, plica, trauma, pes anserine bursitis, and iliotibial-band tendonitis was not different between single-sport and multisport participants (P > .05). Early sport specialization in female adolescents is associated with increased risk of anterior knee-pain disorders including PFP, Osgood Schlatter, Sinding Larsen-Johansson compared with multisport athletes.

The prevalence of sport specialization in high school athletes is unknown. This information is needed to determine the scope of this issue in an active population. To determine the prevalence of sport specialization in high school athletes and to determine if specialization is influenced by classification method, year in school, sex, and school size. A secondary purpose was to determine if highly specialized athletes would be more likely to report a history of lower extremity injuries. Cross-sectional study; Level of evidence, 3. High school athletes between the ages of 13 and 18 years from 2 local high schools completed both a sport specialization survey and an injury history survey. Athletes were classified into low, moderate, or high specialization groups using a recently developed 3-point system and were also classified using a self-classification method. A total of 302 athletes completed the surveys and were classified as low specialization (n = 105, 34.8%), moderate specialization (n = 87, 28.8%), or high specialization (n = 110, 36.4%). Athletes from the small school were more likely to be classified in the low specialization group (low, 43%; moderate, 32%; high, 25%) compared with those from the large school (low, 26%; moderate, 26%; high, 48%) (P < .001). Athletes in the high specialization group were more likely to report a history of overuse knee injuries (n = 18) compared with moderate (n = 8) or low specialization (n = 7) athletes (P = .048). Athletes who trained in one sport for more than 8 months out of the year were more likely to report a history of knee injuries (odds ratio [OR], 2.32; 95% CI, 1.22-4.44; P = .009), overuse knee injuries (OR, 2.93; 95% CI, 1.16-7.36; P = .018), and hip injuries (OR, 2.74; 95% CI, 1.09-6.86; P = .026). Using the self-classification method, more participants self-classified as multisport (n = 213, 70.5%) than single sport (n = 89, 29.5%). Athletes from the small school were more likely to classify themselves as

Sport-Specific Assessment of the Effectiveness of Neuromuscular Training in Young Athletes

Neuromuscular training in young athletes improves performance and decreases the risk of injuries during sports activities. These effects are primarily ascribed to the enhancement of muscle strength and power but also balance, speed and agility. However, most studies have failed to demonstrate significant improvement in these abilities. This is probably due to the fact that traditional tests do not reflect training methods (e.g., plyometric training vs. isometric or isokinetic strength testing, dynamic balance training vs. static balance testing). The protocols utilized in laboratories only partially fulfill the current needs for testing under sport-specific conditions. Moreover, laboratory testing usually requires skilled staff and a well equipped and costly infrastructure. Nevertheless, experience demonstrates that high-technology and expensive testing is not the only way to proceed. A number of physical fitness field tests are available today. However, the low reliability and limited number of parameters retrieved from simple equipment used also limit their application in competitive sports. Thus, there is a need to develop and validate a functional assessment platform based on portable computerized systems. Variables obtained should be directly linked to specific features of particular sports and capture their complexity. This is essential for revealing weak and strong components of athlete performance and design of individually-tailored exercise programs. Therefore, identifying the drawbacks associated with the assessment of athlete performance under sport-specific conditions would provide a basis for the formation of an innovative approach to their long-term systematic testing. This study aims (i) to review the testing methods used for the evaluation of the effect of neuromuscular training on sport-specific performance in young athletes, (ii) to introduce stages within the Sport Longlife Diagnostic Model, and (iii) to propose future research in this topic

Many coaches, parents, and children believe that the best way to develop elite athletes is for them to participate in only 1 sport from an early age and to play it year-round. However, emerging evidence to the contrary indicates that efforts to specialize in 1 sport may reduce opportunities for all children to participate in a diverse year-round sports season and can lead to lost development of lifetime sports skills. Early sports specialization may also reduce motor skill development and ongoing participation in games and sports as a lifestyle choice. The purpose of this review is to employ the current literature to provide evidence-based alternative strategies that may help to optimize opportunities for all aspiring young athletes to maximize their health, fitness, and sports performance. Nonsystematic review with critical appraisal of existing literature. Clinical review. Level 4. Based on the current evidence, parents and educators should help provide opportunities for free unstructured play to improve motor skill development and youth should be encouraged to participate in a variety of sports during their growing years to influence the development of diverse motor skills. For those children who do choose to specialize in a single sport, periods of intense training and specialized sport activities should be closely monitored for indicators of burnout, overuse injury, or potential decrements in performance due to overtraining. Last, the evidence indicates that all youth should be involved in periodized strength and conditioning (eg, integrative neuromuscular training) to help them prepare for the demands of competitive sport participation, and youth who specialize in a single sport should plan periods of isolated and focused integrative neuromuscular training to enhance diverse motor skill development and reduce injury risk factors.

This paper introduces a new sport and athlete development framework that has been generated by multidisciplinary sport practitioners. By combining current theoretical research perspectives with extensive empirical observations from one of the world's leading sport agencies, the proposed FTEM (Foundations, Talent, Elite, Mastery) framework offers broad utility to researchers and sporting stakeholders alike. FTEM is unique in comparison with alternative models and frameworks, because it: integrates general and specialised phases of development for participants within the active lifestyle, sport participation and sport excellence pathways; typically doubles the number of developmental phases (n = 10) in order to better understand athlete transition; avoids chronological and training prescriptions; more optimally establishes a continuum between participation and elite; and allows full inclusion of many developmental support drivers at the sport and system levels. The FTEM framework offers a viable and more flexible alternative for those sporting stakeholders interested in managing, optimising, and researching sport and athlete development pathways.

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. To determine whether functional movement deficits exist in SSS athletes compared with multi-sport (M-S) athletes. Cross-sectional study. Soccer practice fields. 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. 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. 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 χ(2) test. The α level was set a priori at .05. 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 χ(2) 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 ([Formula: see text] = 1.999, P = .57). Participation in soccer alone compared with multiple sports did not affect LESS scores in adolescent female soccer players. However, the LESS scores indicated that most female adolescent

Recent studies have shown that athletes’ domain specific perceptual-cognitive expertise can transfer to everyday tasks. Here we assessed the perceptual-cognitive expertise of athletes and non-athletes using sport specific and non-sport specific biological motion perception (BMP) tasks. Using a virtual environment, university-level soccer players and university students’ non-athletes were asked to perceive the direction of a point-light walker and to predict the trajectory of a masked-ball during a point-light soccer kick. Angles of presentation were varied for orientation (upright, inverted) and distance (2 m, 4 m, 16 m). Accuracy and reaction time were measured to assess observers’ performance. The results highlighted athletes’ superior ability compared to non-athletes to accurately predict the trajectory of a masked soccer ball presented at 2 m (reaction time), 4 m (accuracy and reaction time), and 16 m (accuracy) of distance. More interestingly, experts also displayed greater performance compared to non-athletes throughout the more fundamental and general point-light walker direction task presented at 2 m (reaction time), 4 m (accuracy and reaction time), and 16 m (reaction time) of distance. In addition, athletes showed a better performance throughout inverted conditions in the walker (reaction time) and soccer kick (accuracy and reaction time) tasks. This implies that during human BMP, athletes demonstrate an advantage for recognizing body kinematics that goes beyond sport specific actions. PMID:26388828

Half-time strategies to enhance second-half performance in team-sports players: a review and recommendations.

A number of intermittent team sports require that two consecutive periods of play (lasting for ~30-45 min) are separated by a 10-20 min half-time break. The half-time practices employed by team-sports players generally include returning to the changing rooms, temporarily relaxing from the cognitive and physical demands of the first half, rehydration and re-fuelling strategies, addressing injury or equipment concerns, and receiving tactical instruction and coach feedback. However, the typically passive nature of these actions has been associated with physiological changes that impair performance during the second half. Both physical and cognitive performances have been found to decline in the initial stages of subsequent exercise that follows half-time. An increased risk of injury has also been observed during this period. Therefore, half-time provides sports scientists and strength and conditioning coaches with an opportunity to optimise second-half performance. An overview of strategies thought to benefit team-sports athletes is presented; specifically, the efficacy of heat maintenance strategies (including passive and active methods), post-activation potentiation, hormonal priming, and modified hydro-nutritional practices are discussed. A theoretical model of applying these strategies in a manner that compliments current practice is also offered.
