Helmets and Mouth Guards: The Role of Personal Equipment in Preventing Sport-Related Concussions

PubMed Central

Daneshvar, Daniel H.; Baugh, Christine M.; Nowinski, Christopher J.; McKee, Ann C.; Stern, Robert A.; Cantu, Robert C.

2010-01-01

Every year, millions of athletes in the United States experience concussions. With athletes at all levels of play getting bigger, faster, and stronger, it has been suggested that newer technologies may provide an opportunity to reduce the risk and severity of these all too frequent injuries. Although helmets have been shown to decrease the rate of catastrophic head injuries, and mouth guards have decreased the risk of dental and oral injuries, the protective effect of helmets and mouth guards on concussions has not been conclusively demonstrated. In this review, the current literature pertaining to the effect that equipment has on concussions is evaluated. Understanding the role that this equipment plays in preventing concussions is complicated by many factors, such as selection bias in non-randomized studies, variations in playing style, and risk compensation in sports with mandatory protective equipment. At this point, there is little evidence supporting the use of specific helmets or mouth guards to prevent concussions outside of specific sports such as cycling, skiing, and snowboarding. Improving coach and player education about proper concussion management, encouraging neck strengthening exercises, and minimizing high-risk impacts may provide a more fruitful avenue to reduce concussions in sports.

Every year > 600,000 sports and recreation related eye injuries occur, out of which roughly 13,500 of these result in permanent loss of sight. Up to 90% of these sports related eye injuries are preventable by using adequate eye protection equipment. Protective eyewear is made of polycarbonate, a highly impact-resistant plastic which is now easily available as prescription and non-prescription eyewear and all players should be encouraged to use them. The medical officers by educating their patients regarding the risks of eye injuries in various sports and the confirmed benefits of using protective equipment have the potential to prevent injury to over thousands of eyes every year. The medical fraternity can also play a very important role in educating the coaches, parents, and children and thus put an end to unnecessary blindness and vision loss from sports related ocular injuries, therefore ensuring a lifetime of healthy vision.

To examine the independent, competing, and interactive effects of perceived availability of specific types of media in the home and neighborhood sport facilities on adolescents' leisure-time physical activity (PA). Survey data from 34 369 students in 42 Hong Kong secondary schools were collected (2006-07). Respondents reported moderate-to-vigorous leisure-time PA, presence of sport facilities in the neighborhood and of media equipment in the home. Being sufficiently physically active was defined as engaging in at least 30 minutes of non-school leisure-time PA on a daily basis. Logistic regression and post-estimation linear combinations of regression coefficients were used to examine the independent and competing effects of sport facilities and media equipment on leisure-time PA. Perceived availability of sport facilities was positively (OR(boys) = 1.17; OR(girls) = 1.26), and that of computer/Internet negatively (OR(boys) = 0.48; OR(girls) = 0.41), associated with being sufficiently active. A significant positive association between video game console and being sufficiently active was found in girls (OR(girls) = 1.19) but not in boys. Compared with adolescents without sport facilities and media equipment, those who reported sport facilities only were more likely to be physically active (OR(boys) = 1.26; OR(girls) = 1.34), while those who additionally reported computer/Internet were less likely to be physically active (OR(boys) = 0.60; OR(girls) = 0.54). Perceived availability of sport facilities in the neighborhood may positively impact on adolescents' level of physical activity. However, having computer/Internet may cancel out the effects of active opportunities in the neighborhood. This suggests that physical activity programs for adolescents need to consider limiting the access to computer-mediated communication as an important intervention component.

Spinal cord injury is a nonfatal, catastrophic consequence of wave-riding sports. With surfing at the core, a multitude of activities have evolved that attempt to harness the power of ocean waves. The unique qualities of each wave-riding sport, in combination with the environmental factors of the ocean, define the risk for potential injuries. As wave-riding sports have become more advanced, athletes continue to push physical barriers. Taller waves are attempted while incorporating aerial maneuvers, all without protective equipment.

Lees, Adrian

2003-09-01

The major racket sports include badminton, squash, table tennis and tennis. The growth of sports science and the commercialization of racket sports in recent years have focused attention on improved performance and this has led to a more detailed study and understanding of all aspects of racket sports. The aim here, therefore, is to review recent developments of the application of science to racket sports. The scientific disciplines of sports physiology and nutrition, notational analysis, sports biomechanics, sports medicine, sports engineering, sports psychology and motor skills are briefly considered in turn. It is evident from these reviews that a great deal of scientific endeavour has been applied to racket sports, but this is variable across both the racket sports and the scientific disciplines. A scientific approach has helped to: implement training programmes to improve players' fitness; guide players in nutritional and psychological preparation for play; inform players of the strategy and tactics used by themselves and their opponents; provide insight into the technical performance of skills; understand the effect of equipment on play; and accelerate the recovery from racket-arm injuries. Racket sports have also posed a unique challenge to scientists and have provided vehicles for developing scientific methodology. Racket sports provide a good model for investigating the interplay between aerobic and anaerobic metabolism and the effect of nutrition, heat and fatigue on performance. They have driven the development of mathematical solutions for multi-segment interactions within the racket arm during the performance of shots, which have contributed to our understanding of the mechanisms of both performance and injury. They have provided a unique challenge to sports engineers in relation to equipment performance and interaction with the player. Racket sports have encouraged developments in notational analysis both in terms of analytical procedures and the conceptualization of strategy and tactics. Racket sports have provided a vehicle for investigating fast interceptive actions, hand-eye coordination and perception-action coupling in the field of motor control. In conclusion, science has contributed considerably to our knowledge and understanding of racket sports, and racket sports have contributed to science by providing unique challenges to researchers.

Elite-adapted wheelchair sports performance: a systematic review.

PubMed

Perret, Claudio

2017-01-01

Elite-adapted sports performance has considerably improved over the last decades and winning or losing races at Paralympic Games is often a matter of a split second. In other words, every single detail counts, which underlines the necessity of optimizing training interventions and equipment for athletes in order to achieve top-class performance. However, to date, studies which include Paralympic elite athletes are scarce. A comprehensive literature search was performed to identify potential strategies and interventions in order to optimize elite-adapted wheelchair sports performance, whereas the focus lay on respiratory muscle training (RMT), cooling (CI) and nutritional interventions (NI) as well as on individual equipment adaptations (IEA). The total number of studies identified for the final analysis was six for RMT, two for CI, three for NI and seven for IEA, respectively. Results point predominantly towards performance enhancing benefits for CI and IEA, whereas NI and RMT provided inhomogenous findings. In comparison to the able-bodied population, research in the field of Paralympic elite sport is scarce. CI and IEA seem to have significant performance enhancing benefits, whereas NI and RMT revealed controversial findings. However, due to the limited number of elite athletes with a spinal cord injury available to participate in scientific studies, general conclusions are difficult to make at this stage and in daily practice recommendations are still given mainly on an individual basis or based on personal experiences of coaches, athletes and scientists. Implications for Rehabilitaton Based on the knowledge gained in elite sports, wheelchair equipment could be optimized also for daily use. Elite sports performance could inspire wheelchair users to achieve their personal fitness goals.

[Are newspapers a reliable source of information about doping in sports?].

Durrieu, Geneviève; Gorsse, Elisabeth; Montastruc, Jean-Louis

2004-01-01

To study the coverage by French newspapers of doping in sports, we performed a systematic review of articles appearing between January and March 2003 on the following French websites: L'Equipe, Le Monde, Le Figaro, Libération, La Dépêche du Midi and Agence France-Presse (AFP). We recorded a total of 58 articles about doping. Among them, 48 (83%) were collected from the AFP news. L'Equipe, a French sports newspaper, published seven articles (12%). Most of the recorded data reported results of worldwide antidoping control (71%). No information about new drugs was found. The analysis of the selected articles pointed out the following: (i) the seriousness of observations related to doping since, during this 3-month period, we noted two deaths of athletes; (ii) the risks associated with the use of dietary supplements, particularly products including amphetamine derivatives; (iii) the interest in judicial investigation as an information source about doping in sports (investigation of suspicious deaths of Italian football players); and (iv) identification of the sports involved in doping (cycling, but also athletics, football, rugby). Systematic analysis of newspaper reports can be considered as a relevant method for monitoring the pharmacovigilance and pharmacoepidemiology of doping in sports.

A high percentage of all sports injuries occur during school sports. The aim of this study was to collect statements and opinions of sports teachers for safety in physical education. In a cross-sectional study, 296 teachers (202 with, 94 without a teaching qualification in "exercise and sports") at 77 Tyrolean "New Middle Schools" (former secondary schools) were interviewed. They judged various statements on school sports safety using a 5-point verbal rating scale. Irrespective of gender, teachers with a teaching qualification stated significantly more frequently (p = 0.015) that they have participated in continuing education on accident prevention than had their colleagues without qualification. The same applies to the checking of gymnastic and sports equipment before use (p < 0.001) and warming up at the beginning of the lesson (p < 0.001). Female sports teachers allowed their pupils more often (p = 0.002) to participate without adequate sportswear in physical education than did their male counterparts. Of all respondents, 57 % knew about technical faults in sports halls, which have also been reported to the school administration. In more than half (58 %) of these, reported defects were repaired completely and in one-third (36 %), a partial repair was reported. Participants estimated that the major risk for school sports injuries was due to the low motor skills of the pupils, inhomogeneous groups, large numbers of pupils, outdated sports equipment, and ball games. Since about a third of all surveyed teachers had no teaching qualification in exercise and sports, this group should come into the focus of regular continuing education in accident prevention. © Georg Thieme Verlag KG Stuttgart · New York.

2001-04-01

Over the last few years, changes in cutaneous homoeostasis resulting from sports activities have been reported. In particular, alterations in sweating mechanisms, the hydrolipid barrier, and surface bacterial flora, together with exposure to atmospheric conditions and the need to use medicaments, detergents, and other topical substances, predispose subjects to allergic contact dermatitis. To evaluate the incidence of allergic contact dermatitis in a group of young people practising sports activities. Patch tests were performed to confirm the diagnosis of irritant or allergic dermatitis; in addition, the radioallergoabsorbent test (RAST) to latex was evaluated in the group studied. Allergic contact dermatitis caused by thiourams (23.3%) and mercaptobenzothiazole (20.9%) was prevalent. Other haptens, such as benzocaine and nickel, which are contained in clothing, equipment, topical medicaments, and creams used for massage, were also allergenic. In two cases, RAST positivity to latex was registered. -The results suggest that close contact with sports equipment may increase the incidence of allergic contact dermatitis. Students practising certain sports may have "professional" allergic contact dermatitis to additives used in the production of rubber.

Current Perspectives on Profiling and Enhancing Wheelchair Court Sport Performance.

PubMed

Paulson, Thomas; Goosey-Tolfrey, Victoria

2017-03-01

Despite the growing interest in Paralympic sport, the evidence base for supporting elite wheelchair sport performance remains in its infancy when compared with able-bodied (AB) sport. Subsequently, current practice is often based on theory adapted from AB guidelines, with a heavy reliance on anecdotal evidence and practitioner experience. Many principles in training prescription and performance monitoring with wheelchair athletes are directly transferable from AB practice, including the periodization and tapering of athlete loads around competition, yet considerations for the physiological consequences of an athlete's impairment and the interface between athlete and equipment are vital when targeting interventions to optimize in-competition performance. Researchers and practitioners are faced with the challenge of identifying and implementing reliable protocols that detect small but meaningful changes in impairment-specific physical capacities and on-court performance. Technologies to profile both linear and rotational on-court performance are an essential component of sport-science support to understand sport-specific movement profiles and prescribe training intensities. In addition, an individualized approach to the prescription of athlete training and optimization of the "wheelchair-user interface" is required, accounting for an athlete's anthropometrics, sports classification, and positional role on court. In addition to enhancing physical capacities, interventions must focus on the integration of the athlete and his or her equipment, as well as techniques for limiting environmental influence on performance. Taken together, the optimization of wheelchair sport performance requires a multidisciplinary approach based on the individual requirements of each athlete.

The frequency and potential long-term effects of sport-related traumatic brain injuries (TBI) make it a major public health concern. The culture within contact sports, such as ice hockey, encourages aggression that puts youth at risk of TBI such as concussion. Newspaper reports play an important role in conveying and shaping the culture around health-related behaviors. We qualitatively studied reports about sport-related TBI in four major North American newspapers over the last quarter-century. We used the grounded-theory approach to identify major themes and then did a content analysis to compare the frequency of key themes between 1998-2000 and 2009-2011. The major themes were: perceptions of brain injury, aggression, equipment, rules and regulations, and youth hockey. Across the full study period, newspaper articles from Canada and America portrayed violence and aggression that leads to TBI both as integral to hockey and as an unavoidable risk associated with playing the game. They also condemned violence in ice hockey, criticized the administrative response to TBI, and recognized the significance of TBI. In Canada, aggression was reported more often recently and there was a distinctive shift in portraying protective equipment as a solution to TBI in earlier years to a potential contributing factor to TBI later in the study period. American newspapers gave a greater attention to 'perception of risks' and the role of protective equipment, and discussed TBI in a broader context in the recent time period. Newspapers from both countries showed similar recent trends in regards to a need for rule changes to curb youth sport-related TBI. This study provides a rich description of the reporting around TBI in contact sport. Understanding this reporting is important for evaluating whether the dangers of sport-related TBI are being appropriately communicated by the media.

Football, one of the country's most popular team sports, is associated with the largest overall number of sports-related, catastrophic, cervical spine injuries in the United States (Mueller, 2007). Patient handling can be hindered by the protective sports equipment worn by the athlete. Improper stabilization of these patients can exacerbate neurologic injury. Because of the lack of consensus on the best method for equipment removal, a study was performed comparing three techniques: full body levitation, upper torso tilt, and log roll. These techniques were performed on an intact and lesioned cervical spine cadaveric model simulating conditions in the emergency department. The levitation technique was found to produce motion in the anterior and right lateral directions. The tilt technique resulted in motions in the posterior left lateral directions, and the log roll technique generated motions in the right lateral direction and had the largest amount of increased instability when comparing the intact and lesioned specimen. These findings suggest that each method of equipment removal displays unique weaknesses that the practitioner should take into account, possibly on a patient-by-patient basis.

Sport participation makes an important contribution to children's overall physical activity. Understanding influences on sports participation is important and the family environment is considered key, however few studies have explored the mechanisms by which the family environment influences children's sport participation. The purpose of this study was to examine whether attitude, perceived behavioural control, health belief and enjoyment mediate associations between the family environment and 10-12 year-old children's sports participation. Children aged 10-12 years ( = 7,234) and one of their parents (n = 6,002) were recruited from 175 schools in seven European countries in 2010. Children self-reported their weekly duration of sports participation, physical activity equipment items at home and the four potential mediator variables. Parents responded to items on financial, logistic and emotional support, reinforcement, modelling and co-participation in physical activity. Cross-sectional single and multiple mediation analyses were performed for 4952 children with complete data using multi-level regression analyses. Availability of equipment (OR = 1.16), financial (OR = 1.53), logistic (OR = 1.47) and emotional (OR = 1.51) support, and parental modelling (OR = 1.07) were positively associated with participation in ≥  30 mins/wk of sport. Attitude, beliefs, perceived behavioural control and enjoyment mediated and explained between 21-34% of these associations. Perceived behavioural control contributed the most to the mediated effect for each aspect of the family environment. Both direct (unmediated) and indirect (mediated) associations were found between most family environment variables and children's sports participation. Thus, family-based physical activity interventions that focus on enhancing the family environment to support children's sport participation are warranted.

Student's t test and chi-square test, logistic regression. snow injuries occurring in the ski resorts of agordino (Belluno), Arabba-Marmolada, Alleghe and Falcade between December 2006 and April 2007. Data were collected from the database of the Agordo Public Hospital, of the 118 Emergency service of Pieve di Cadore, and of several ski resorts. age, sex, country area, kind of injury, numbers, severity and type of trauma, injury time, prognosis, part of the body injured. the two sports differ with regard to trauma types: sprains and distortions are more frequent in skiers, whereas fractures (breaks) are more frequent in the snowboard. Lower limbs (knee) in ski and upper limbs (wrist) in snowboard are the main lesion sites. With regard to the ankle's injuries, no difference was found between the two sport: this contrasts with previous findings reported in the literature. Severity of trauma is not related to the kind of sport. the results of the present study agree with previous findings with regard to the type of lesions observed in the two sports. Among snowboarders, it is possible that recent materials and equipments reduce ankle injury risk. In spite of the differences in equipment and gestures, the consequences of injury are similar in the two sports.

Sports and recreational injuries in children and adolescents: prevention and education.

Davis, Elaine K

2004-01-01

Youth and children's sports are becoming increasingly popular in America. Previous studies have shown that children and adolescents are not small adults in their responses to exercise and stress. As children around the world become involved in more competitive and organized sports activities, the frequency and severity of acute and overuse injuries continue to rise. Safety guidelines, protective equipment and prevention education are crucial to reducing pediatric recreational and sports injuries. Preventing injuries and ensuring safe athletic practices are necessary for children and adolescents to continue to receive benefits from organized sports and recreational activities. Efforts to minimize these injuries are warranted both to ensure the long-term health of children and to reduce medical costs.

Traumatic brain injury (TBI) is a major cause of lifelong disability and death worldwide. Sport-related traumatic brain injury is an important public health concern. The purpose of this review was to highlight the importance of sport-related concussions. Concussion refers to a transient alteration in consciousness induced by external biomechanical forces transmitted directly or indirectly to the brain. It is a common, although most likely underreported, condition. Contact sports such as American football, rugby, soccer, boxing, basketball and hockey are associated with a relatively high prevalence of concussion. Various factors may be associated with a greater risk of sport-related concussion, such as age, sex, sport played, level of sport played and equipment used. Physical complaints (headache, fatigue, dizziness), behavioral changes (depression, anxiety, irritability) and cognitive impairment are very common after a concussion. The risk of premature return to activities includes the prolongation of post-concussive symptoms and increased risk of concussion recurrence.

Infectious Diseases Associated With Organized Sports and Outbreak Control.

Davies, H Dele; Jackson, Mary Anne; Rice, Stephen G

2017-10-01

Participation in organized sports has a variety of health benefits but also has the potential to expose the athlete to a variety of infectious diseases, some of which may produce outbreaks. Major risk factors for infection include skin-to-skin contact with athletes who have active skin infections, environmental exposures and physical trauma, and sharing of equipment and contact with contaminated fomites. Close contact that is intrinsic to team sports and psychosocial factors associated with adolescence are additional risks. Minimizing risk requires leadership by the organized sports community (including the athlete's primary care provider) and depends on outlining key hygiene behaviors, recognition, diagnosis, and treatment of common sports-related infections, and the implementation of preventive interventions.

Dominance and noncommutativity effects in concept conjunctions: extensional or intensional basis?

PubMed

Storms, G; de Boeck, P; Van Mechelen, I; Geeraerts, D

1993-11-01

Dominance and noncommutativity effects are investigated in relative clause descriptions of five conjunctive concepts (birds and pets, sports and games, vehicles and machines, office equipment and writing implements, and shoes and sports equipment). Both asymmetry phenomena are studied at the extensional level (using membership ratings) and at the intensional level (using feature-importance ratings). A clear dominance effect was found for both the membership ratings and the feature-importance ratings, whereas the noncommutativity effect emerged only occasionally in the membership ratings and almost never in the feature-importance ratings. The data suggested that the dominance effect and the much weaker noncommutativity effect have an extensional basis.

While a growing number of children are playing football (soccer), there are limited data on prevalence of injuries, actual use of football safety equipment (SE), and parental attitudes about football SE. We distributed a self-administered survey by mail to parents of all players enrolled in a community recreation youth football program. Parents of 865 children responded. Overall, 32 (3.7%) children were reported as having injuries requiring medical/dental evaluation. Upper/lower extremities were the most commonly injured sites. Shinguards (SGs) were the only equipment commonly used. While there was high parental support for SG use (97.4%) and moderate support for mouthguards (MGs; 53.8%), there was less support for other SE. Many parents were unfamiliar with available SE, but they were mostly willing to pay for it. In a community youth sports program, reports of football injuries were low as was the use of football SE other than SGs.

Despite the widely acknowledged public health importance of physical activity (PA), few studies have examined levels of PA in Bangladesh. The purpose of this study was to investigate the patterns and correlates of PA in adolescents in Bangladesh. Cross-sectional survey. A total of 798 students, aged 13-17 years; 48% girls, from eight purposively selected secondary schools in Dhaka city, Bangladesh completed a self-administered questionnaire including the 3-Day PA Recall. Parents completed a separate questionnaire to provide household/family-level data. Multilevel generalized linear modelling was used to identify the correlates of PA for boys and girls. Two-thirds (66%) of the adolescents met the recommendations of 60 min/day of moderate to vigorous PA (MVPA) daily, with more boys than girls (76% and 55%, respectively). The most common activities reported were walking for travel (42%), cricket (33%) and household chores (30%). Multivariable modelling showed that girls' PA was positively associated with mother's education level, walking to school, involvement in school sports and having home sports equipment. Boys' PA was positively associated with mother's employment, having home sports equipment, having a playground at school and walking to school. One third of adolescents in Bangladesh were insufficiently active with girls less active than boys. Walking to school and access to sports facilities including playgrounds and home equipment may be important to promote activity among Bangladeshi adolescents, with special attention to the girls.

The peripheral blood stem cell transplantation (PBSCT) represents a specific, but stressful therapy for hemato-oncological diseases. While for adults, data suggest positive eff ects for a supportive sport therapy, this question is not evaluated sufficiently for children. The objective of this study was to examine the integration of sports activity into pediatric PBSCT and to indicate attainable results. This 2-step case-control-study included 23 children and adolescents from the PBSCT: During the isolation phase 13 patients trained 3 times per week on a cycle ergometer and passed a course with different sports equipment. Apart from recording physiologic adaptations, quality of live was inquired in a pre-post design using questionnaires. Guided interviews according to necessity and requirements for sports activity at the PBSCT unit completed the evaluation and were used for the intervention as well as for the control group (n = 10) without sports therapy. On the ergometer, patients trained average 25 min with 0.6 watt / kg. In the majority, a loss of muscular power could be avoided. Quality of life and fatigue symptoms improved by trend. Interview analysis showed general acceptance of physical activity during PBSCT. After initial skepticism due to the additional burden, our implementation study showed the feasibility of supportive sports therapy in PBSCT. Quality and flexibility of the equipment should be higher than normal and different physical and psychological conditions of the patients should be anticipated and integrated into the training program.

Direct and indirect associations between the family physical activity environment and sports participation among 10–12 year-old European children: testing the EnRG framework in the ENERGY project

PubMed Central

2013-01-01

Background Sport participation makes an important contribution to children’s overall physical activity. Understanding influences on sports participation is important and the family environment is considered key, however few studies have explored the mechanisms by which the family environment influences children’s sport participation. The purpose of this study was to examine whether attitude, perceived behavioural control, health belief and enjoyment mediate associations between the family environment and 10–12 year-old children’s sports participation. Methods Children aged 10–12 years ( = 7234) and one of their parents (n = 6002) were recruited from 175 schools in seven European countries in 2010. Children self-reported their weekly duration of sports participation, physical activity equipment items at home and the four potential mediator variables. Parents responded to items on financial, logistic and emotional support, reinforcement, modelling and co-participation in physical activity. Cross-sectional single and multiple mediation analyses were performed for 4952 children with complete data using multi-level regression analyses. Results Availability of equipment (OR = 1.16), financial (OR = 1.53), logistic (OR = 1.47) and emotional (OR = 1.51) support, and parental modelling (OR = 1.07) were positively associated with participation in ≥ 30mins/wk of sport. Attitude, beliefs, perceived behavioural control and enjoyment mediated and explained between 21-34% of these associations. Perceived behavioural control contributed the most to the mediated effect for each aspect of the family environment. Conclusions Both direct (unmediated) and indirect (mediated) associations were found between most family environment variables and children’s sports participation. Thus, family-based physical activity interventions that focus on enhancing the family environment to support children’s sport participation are warranted. PMID:23374374

Therapists treating athletes with hand and wrist injuries may be involved in all stages of recovery, from the acute phase to return to sport. This article gives case examples of how creative use of custom and commercially available orthoses, splints, tape, and braces can augment various stages of recovery. Understanding the specific demands of the sport and respect for the standards of care are imperative to fabricating or fitting an athlete with the best device or customization of the athlete's own equipment for a safe return to sport.

Abernethy, Liz; Bleakley, Chris

2007-01-01

This systematic review set out to identify randomised controlled trials and controlled intervention studies that evaluated the effectiveness of preventive strategies in adolescent sport and to draw conclusions on the strength of the evidence. A literature search in seven databases (Medline, SportDiscus, EMBASE, CINAHL, PEDro, Cochrane Review and DARE) was carried out using four keywords: adolescent, sport, injury and prevention (expanded to capture any relevant literature). Assessment of 154 papers found 12 studies eligible for inclusion. It can be concluded that injury prevention strategies that focus on preseason conditioning, functional training, education, balance and sport‐specific skills, which should be continued throughout the sporting season, are effective. The evidence for the effectiveness of protective equipment in injury prevention is inconclusive and requires further assessment. PMID:17496070

2013-01-01

Urban parks, as one of the recreational and sports sectors, could cause serious injuries among different ages if the safety issues in their design are not considered. These injuries can result from the equipment in the park, including play and sports equipment, or even from environmental factors, too. Lack of safety benchmark in parks will impact on the development of future proposals. In this article, attempts are made to survey the important safety factors in the urban parks including playgrounds, fitness equipment, pedestrian surface and environmental factors into a risk assessment. Hence, a checklist of safety factors was used. A Yes or No descriptor was allocated to any factor for determining safety level. The study also suggests recommendations for future planning concerning existing failures for designers. It was found that the safety level of the regional and local parks differ from each other.

Sport-related concussions in adolescent athletes: a critical public health problem for which prevention remains an elusive goal

PubMed Central

Fidrocki, Diana; Parachuri, Venu

2017-01-01

Sport-related concussions in young athletes are common, generally under reported and often unrecognized. Preventive strategies include education, modification of sport rules, use of equipment such as headgears, face masks and mouth guards, and neck muscle training. Evidence is limited to support effectiveness of these preventive measures with the exception of rule modification in some sports. In the United States, laws have been enacted that require medical evaluation and clearance prior to return to play; however, evidence thus far does not show that laws have been effective in reducing the incidence of concussions in sport. More research is needed in all areas of preventive measures. Sports participation is a complex personal decision on the part of the adolescent and his or her family. They should be provided with all information on inherent risks so that they can make an informed decision. PMID:28795000

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

PubMed Central

Zemková, Erika; Hamar, Dušan

2018-01-01

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. Analysis of the literature identified gaps in the current standard testing methods in terms of their low sensitivity in discriminating between athletes of varied ages and performance levels, insufficent tailoring to athlete performance level and individual needs, a lack of specificity to the requirements of particular sports and also in revealing the effect of training. In order to partly fill in these gaps, the Sport Longlife Diagnostic Model was proposed. PMID:29695970

Rugby Union is one of the most popular sports in Ireland. Participation in all sports carries risk, and there is an onus on governing bodies and those involved in sport to minimise this risk using injury prevention and management programmes. The aim of this study was to evaluate the current status of medical personnel, facilities and equipment in Rugby Union clubs in Ireland. A nationwide cross sectional survey of affiliated clubs in Ireland was undertaken at the beginning of the 2011-2012. Clubs were surveyed on a range of variables including their medical personnel, facilities, equipment, policies and concussion. 47.7 % of those surveyed responded. The majority reported involvement of appropriate medically qualified personnel, having a dedicated medical area/room, a first aid kit and defibrillator, and a demand for first aid courses. This survey provided key information on the current medical status of clubs in Ireland to the governing body. Many clubs have adequate medical resources in place, however a large number do not have medical professionals working with them or own basic medical equipment. The results of this study have lead to the development and implementation of a rugby specific injury prevention and management programme for medical and non-medical personnel at all levels of the game in Ireland.

Body-Cooling Paradigm in Sport: Maximizing Safety and Performance During Competition.

PubMed

Adams, William M; Hosokawa, Yuri; Casa, Douglas J

2016-12-01

Although body cooling has both performance and safety benefits, knowledge on optimizing cooling during specific sport competition is limited. To identify when, during sport competition, it is optimal for body cooling and to identify optimal body-cooling modalities to enhance safety and maximize sport performance. A comprehensive literature search was conducted to identify articles with specific context regarding body cooling, sport performance, and cooling modalities used during sport competition. A search of scientific peer-reviewed literature examining the effects of body cooling on exercise performance was done to examine the influence of body cooling on exercise performance. Subsequently, a literature search was done to identify effective cooling modalities that have been shown to improve exercise performance. The cooling modalities that are most effective in cooling the body during sport competition depend on the sport, timing of cooling, and feasibility based on the constraints of the sports rules and regulations. Factoring in the length of breaks (halftime substitutions, etc), the equipment worn during competition, and the cooling modalities that offer the greatest potential to cool must be considered in each individual sport. Scientific evidence supports using body cooling as a method of improving performance during sport competition. Developing a strategy to use cooling modalities that are scientifically evidence-based to improve performance while maximizing athlete's safety warrants further investigation.

A prototype system for monitoring, transmitting and processing performance data in sports for the purpose of providing feedback has been developed. During training, athletes are equipped with a mobile device and wireless sensors using the ANT protocol in order to acquire biomechanical, physiological and other sports specific parameters. The measured data is buffered locally and forwarded via the Internet to a server. The server provides experts (coaches, biomechanists, sports medicine specialists etc.) with remote data access, analysis and (partly automated) feedback routines. In this way, experts are able to analyze the athlete’s performance and return individual feedback messages from remote locations. PMID:22163490

The estimated reduction in the odds of loss-of-control type crashes for sport utility vehicles equipped with electronic stability control.

PubMed

Green, Paul E; Woodrooffe, John

2006-01-01

Using data from the NASS General Estimates System (GES), the method of induced exposure was used to assess the effects of electronic stability control (ESC) on loss-of-control type crashes for sport utility vehicles. Sport utility vehicles were classified into crash types generally associated with loss of control and crash types most likely not associated with loss of control. Vehicles were then compared as to whether ESC technology was present or absent in the vehicles. A generalized additive model was fit to assess the effects of ESC, driver age, and driver gender on the odds of loss of control. In addition, the effects of ESC on roads that were not dry were compared to effects on roads that were dry. Overall, the estimated percentage reduction in the odds of a loss-of-control crash for sport utility vehicles equipped with ESC was 70.3%. Both genders and all age groups showed reduced odds of loss-of-control crashes, but there was no significant difference between males and females. With respect to driver age, the maximum percentage reduction of 73.6% occurred at age 27. The positive effects of ESC on roads that were not dry were significantly greater than on roads that were dry.

Descriptive epidemiology of Paralympic sports injuries.

PubMed

Webborn, Nick; Emery, Carolyn

2014-08-01

Paralympic sports have seen an exponential increase in participation since 16 patients took part in the first Stoke Mandeville Games on the opening day of the 1948 London Olympic Games. More than 4,000 athletes took part in the London 2012 Paralympic Games. Few sporting events have seen such rapid evolution. This rapid pace of change also has meant challenges for understanding the injury risks of participation, not only because of the variety of sports, impairment types, the evolution of adapted equipment but also because of the inclusion of additional impairment types and development of new sports over time. Early studies were limited in scope but patterns of injuries are slowly emerging within Winter and Summer Paralympic sports. The IPC's London 2012 study is the largest to date with a prospective cohort study involving 49,910 athlete-days. The results identified large differences across sports and highlighted the need for longitudinal sport specific studies rather than solely games-time studies. This will require collaboration with international sports federations to examine injury patterns and risk factors for injury in this population to appropriately inform injury prevention strategies. Further studies will also need to address the impact of sporting participation, injury, and future health. Copyright © 2014 American Academy of Physical Medicine and Rehabilitation.

Robertson, G A J; Wood, A M

2015-06-01

This review aims to provide information on the time taken to resume sport following tibial diaphyseal stress fractures (TDSFs). A systematic search of Medline, EMBASE, CINHAL, Cochrane, Web of Science, PEDro, Sports Discus, Scopus and Google Scholar was performed using the keywords 'tibial', 'tibia', 'stress', 'fractures', 'athletes', 'sports', 'non-operative', 'conservative', 'operative' and 'return to sport'. Twenty-seven studies were included: 16 reported specifically on anterior TDSFs and 5 on posterior TDSFs. The general principles were to primarily attempt non-operative management for all TDSFs and to consider operative intervention for anterior TDSFs that remained symptomatic after 3-6 months. Anterior TDSFs showed a prolonged return to sport. The best time to return to sport and the optimal management modalities for TDSFs remain undefined. Management of TDSFs should include a full assessment of training methods, equipment and diet to modify pre-disposing factors. Future prospective studies should aim to establish the optimal treatment modalities for TDSFs. © The Author 2015. Published by Oxford University Press. All rights reserved.

Gould, Trenton E.; Piland, Scott G.; Caswell, Shane V.; Ranalli, Dennis; Mills, Stephen; Ferrara, Michael S.; Courson, Ron

2016-01-01

Objective: To provide athletic trainers, health care professionals, and all those responsible for the care of athletes with clinical recommendations for preventing and managing sport-related dental and oral injuries. Background: Participation in competitive sports continues to grow at both the interscholastic and intercollegiate levels. Therefore, exposure to, and the incidence of athletic-related injury, including orofacial injury, will also likely increase. At the time of this writing, the leading governing agencies for interscholastic (National Federation of State High School Associations) and intercollegiate (National Collegiate Athletic Association) sports require only protective orofacial equipment (eg, mouthguards) for 5 and 4, respectively, of their sanctioned sports. Although orofacial injuries represent a small percentage of all sport-related injuries, the financial burden associated with these injuries (eg, tooth avulsion) can exceed $15 000 over an adult life. Therefore, effective management of sport-related dental injuries is critical to the long-term financial, physical, and emotional health of people who have experienced dental trauma. Recommendations: Based upon the current evidence regarding sport-related orofacial injury, we provide recommendations related to planning considerations, education, and mouthguard efficacy, material, fabrication, and care considerations. Additionally, suggested best practices for managing sport-related dental injury are also given for athletic trainers and other health care professionals. PMID:27875057

Sports activity increases the risk of maxillofacial fractures. The aim of this study was to analyze trends and characteristics of maxillofacial fractures sustained during sports activity to develop more effective treatments and possibly to prevent injury. Data of 248 patients with maxillofacial fractures sustained during sports activity were retrospectively analyzed based on their clinical records and radiographs. The patients were 226 males (91.1%) and 22 females (8.9%). Their ages ranged from 6 to 70 years and the majority were in their second decade. The fractures were sustained in various sports which included baseball in 85 patients (34.3%), rugby in 40 (16.1%), soccer in 30 (12.1%), softball in 22 (8.9%), golf in 10 (4.0%), hockey in 8 (3.2%), combat sports in 28 (11.3%), and others in 29 (11.7%). The cause of injuries was collision with another player in 97 patients (39.1%), hit by a ball in 89 (35.9%), intended attack in 20 (8.1%), hit by equipment of another player in 15 (6.0%), a fall in 14 (5.6%), and collision with ground equipment in 13 (5.2%). The site of fractures was the mandible in 145 patients (58.5%), midface in 100 (40.3%), and both in 3 (1.2%). Among 210 fracture sites in the mandible, 77 (36.6%) were in the angle, 68 (32.4%) in the symphysis, and 65 (30.9%) in others. Among 103 fractures in the midface, 58 (56.3%) were in the zygoma, 26 (25.2%) in alveolar bone, and 19 (18.4%) in others. Treatment was observation in 67 patients (27.0%), maxillomandibular fixation in 64 (25.8%), open reduction and internal fixation in 63 (25.4%), intramaxillary splinting in 40 (16.1%), transcutaneous reduction in 10 (4.0%), and other procedures in 4 (1.6%). Maxillofacial fractures sustained during sports activity showed characteristic features dependent on the type of sport and cause of injury. © 2018 John Wiley & Sons A/S.

Secure Web site hosting online questionnaire. Medical doctors, physical therapists, and athletic therapists who were members of their respective sport medicine specialty organizations. Professional affiliation and the effect of the following factors were examined: pushy parent, cautious parent, protective equipment, previous injury, musculoskeletal maturity, game importance, position played, team versus individual sport, and time since injury. Recommendation of return to activity after common injuries seen in children and adolescents as described in 5 vignettes; consistency of responses across vignettes. The survey was completed by 464 respondents (34%). There were several differences between the professional groups in their recommendations to return to activity. Most factors studied did not tend to influence the decision to return to activity, although protective equipment often increased the response to return sooner. The number of participants who would return a child to activity sooner or later for each factor varied greatly across the 5 vignettes, except for pushy parent or cautious parent. Management practices of sport medicine clinicians vary according to profession, child, clinical factors, and sport-related factors. Decisions regarding return to play vary according to 5 specific characteristics of each clinical case. These findings help establish areas of consensus and disagreement in the management of children with injuries and safe return to physical activity.

The Current State of Head and Neck Injuries in Extreme Sports

PubMed Central

Sharma, Vinay K.; Rango, Juan; Connaughton, Alexander J.; Lombardo, Daniel J.; Sabesan, Vani J.

2015-01-01

Background: Since their conception during the mid-1970s, international participation in extreme sports has grown rapidly. The recent death of extreme snowmobiler Caleb Moore at the 2013 Winter X Games has demonstrated the serious risks associated with these sports. Purpose: To examine the incidence and prevalence of head and neck injuries (HNIs) in extreme sports. Study Design: Descriptive epidemiological study. Methods: The National Electronic Injury Surveillance System (NEISS) was used to acquire data from 7 sports (2000-2011) that were included in the Winter and Summer X Games. Data from the NEISS database were collected for each individual sport per year and type of HNI. Cumulative data for overall incidence and injuries over the entire 11-year period were calculated. National estimates were determined using NEISS-weighted calculations. Incidence rates were calculated for extreme sports using data from Outdoor Foundation Participation Reports. Results: Over 4 million injuries were reported between 2000 and 2011, of which 11.3% were HNIs. Of all HNIs, 83% were head injuries and 17% neck injuries. The 4 sports with the highest total incidence of HNI were skateboarding (129,600), snowboarding (97,527), skiing (83,313), and motocross (78,236). Severe HNI (cervical or skull fracture) accounted for 2.5% of extreme sports HNIs. Of these, skateboarding had the highest percentage of severe HNIs. Conclusion: The number of serious injuries suffered in extreme sports has increased as participation in the sports continues to grow. A greater awareness of the dangers associated with these sports offers an opportunity for sports medicine and orthopaedic physicians to advocate for safer equipment, improved on-site medical care, and further research regarding extreme sports injuries.

Injury prevention and future research.

PubMed

Emery, Carolyn A

2005-01-01

To critically examine and summarize the literature identifying risk factors and prevention strategies for injury in child and adolescent sport. Seven electronic databases were searched including: Medline, Cumulative Index to Nursing and Allied Health Literature (CINAHL), Psychinfo, Cochrane Database for Systematic and Complete Reviews, Cochrane Controlled Trials Registry, HealthSTAR and SPORTDiscus. Medical subject headings and text words included: athletic injury, sport injury, risk factors, adolescent and child. Additional articles were reviewed based on sport-specific contributions in the previous chapters of this book. Despite the diversity of injuries occurring in various pediatric sporting populations, the uniformity with respect to many of the risk factors identified in the literature is noteworthy (i.e. previous injury, age, sport specificity, psychosocial factors, decreased strength and endurance). The literature is significantly limited with respect to the prospective evaluation of risk factors and prevention strategies for injury in pediatric sport. The consistencies, however, between the adult and pediatric literature are encouraging with respect to prevention strategies involving neuromuscular training programs (i.e. balance training programs) to reduce lower extremity injuries in some sports and the use of sport-specific protective equipment (i.e. helmets). Notwithstanding the limitations in the literature, the successful evaluation of some sport-specific prevention strategies to reduce injury in pediatric sport is encouraging. There is significant opportunity to methodologically improve upon the current pediatric sport injury literature in descriptive surveillance research, risk factor evaluation research, and prevention research. There is a need for prospective studies, ideally randomized controlled trials, in the evaluation of prevention strategies in pediatric sport. The integration of basic science, laboratory and epidemiological research is critical in evaluating the mechanisms associated with injury and injury prevention in pediatric sport. Finally, long-term studies are needed to identify the public health impact of pediatric sport injury.

[Factors conditioning taking up sport activity by disabled people].

PubMed

Plinta, Ryszard; Sobiecka, Joanna

2002-01-01

The aim of the study was to answer the following questions: What factors determine that disabled people take up systematic sport activity or should make such a decision? What reasons are able to eliminate the handicapped from process of regular going in for sport? Three groups of men participated. The group of disabled sportsmen included 39 subjects, the group of non-active disabled people 36 subjects and the group of able-bodied students 45 subjects. All the involved people answered the questions of the questionnaire, which concerned factors associated with sport activity of the handicapped and their socio-demographic characteristics, among other things. The opportunity of improvement of the health status is the main advantage of the sport for disabled people (53%). The chance of self-testing and sport competition was pointed out by 47% of subjects. The most common reason for taking up sport activity was sport passion (over 50%). The others were: possibility of creating new contacts with people, improvement of the physical condition, chance of self-testing and passing free time (23%). The lack of free time was the factor eliminating from sport activity in the second group (28%). The other problem was the shortage of appropriate clubs, equipment, infrastructure etc. (almost 25%). Students concluded that sport for disabled people aims to improve the mental condition mainly (42%). Quite similar percentage of the group (38%) didn't see any reason that was able to exclude the handicapped from goingin for sport. (1) Not only does active going in for sport improve the physical condition of the handicapped but strengthen them psychically as well. (2) The lack of sport activity in disabled people is to a high degree a result of low number of sport clubs, organisations, buildings as well as presence of architectural barriers.

Whole-body vibration exposure in sport: four relevant cases.

PubMed

Tarabini, Marco; Saggin, Bortolino; Scaccabarozzi, Diego

2015-01-01

This study investigates the whole-body vibration exposure in kite surfing, alpine skiing, snowboarding and cycling. The vibration exposure was experimentally evaluated following the ISO 2631 guidelines. Results evidenced that the most critical axis is the vertical one. The weighted vibration levels are always larger than 2.5 m/s(2) and the vibration dose values are larger than 25 m/s(1.75). The exposure limit values of the EU directive are reached after 8-37 min depending on the sport. The vibration magnitude is influenced by the athletes' speed, by their skill level and sometimes by the equipment. The large vibration values suggest that the practice of sport activities may be a confounding factor in the aetiology of vibration-related diseases. The vibration exposure in some sports is expected to be large, but has never been quantified in the literature. Results of experiments performed in cycling, alpine and water sports outlined vibration levels exceeding the EU standard limit values.

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

Sport and early osteoarthritis: the role of sport in aetiology, progression and treatment of knee osteoarthritis.

Sports activities are considered favourable for general health; nevertheless, a possible influence of sports practice on the development of early osteoarthritis (OA) is a cause for concern. A higher incidence of OA in knees and ankles of former high-impact sports players than in those of the normal population has been shown and it is still debatable whether the cause is either to be recognized generically in the higher number of injuries or in a joint overload. The possibility to address knee OA in its early phases may be strictly connected to the modification of specific extrinsic or intrinsic factors, related to the patient in order to save the joint from further disease progression; these include sport practice, equipment and load. Non-surgical therapies such as continuative muscles reinforce and training play a strong role in the care of athletes with early OA, particularly if professional. There is an overall agreement on the need of an early restoring of a proper meniscal, ligament and cartilage integrity in order to protect the knee and resume sports safely, whereas alignment is a point still strongly debatable especially for professional athletes. Remaining questions still to be answered are the risks of different sports in relation to one another, although an actual protective effect of low-impact sports, such as walking, swimming or cycling, has been recognized on the appearance or worsening of OA, the effect of continuing or ceasing to practice a sport on the natural history of early OA, and even following appropriate treatment is still unknown.

What are the most effective risk-reduction strategies in sport concussion?

PubMed

Benson, Brian W; McIntosh, Andrew S; Maddocks, David; Herring, Stanley A; Raftery, Martin; Dvorák, Jirí

2013-04-01

To critically review the evidence to determine the efficacy and effectiveness of protective equipment, rule changes, neck strength and legislation in reducing sport concussion risk. Electronic databases, grey literature and bibliographies were used to search the evidence using Medical Subject Headings and text words. Inclusion/exclusion criteria were used to select articles for the clinical equipment studies. The quality of evidence was assessed using epidemiological criteria regarding internal/external validity (eg, strength of design, sample size/power, bias and confounding). No new valid, conclusive evidence was provided to suggest the use of headgear in rugby, or mouth guards in American football, significantly reduced players' risk of concussion. No evidence was provided to suggest an association between neck strength increases and concussion risk reduction. There was evidence in ice hockey to suggest fair-play rules and eliminating body checking among 11-years-olds to 12-years-olds were effective injury prevention strategies. Evidence is lacking on the effects of legislation on concussion prevention. Equipment self-selection bias was a common limitation, as was the lack of measurement and control for potential confounding variables. Lastly, helmets need to be able to protect from impacts resulting in a head change in velocities of up to 10 and 7 m/s in professional American and Australian football, respectively, as well as reduce head resultant linear and angular acceleration to below 50 g and 1500 rad/s(2), respectively, to optimise their effectiveness. A multifactorial approach is needed for concussion prevention. Future well-designed and sport-specific prospective analytical studies of sufficient power are warranted.

2014-01-01

Objective To present athletic trainers with recommendations for the content and administration of the preparticipation physical examination (PPE) as well as considerations for determining safe participation in sports and identifying disqualifying conditions. Background Preparticipation physical examinations have been used routinely for nearly 40 years. However, considerable debate exists as to their efficacy due to the lack of standardization in the process and the lack of conformity in the information that is gathered. With the continuing rise in sports participation at all levels and the growing number of reported cases of sudden death in organized athletics, the sports medicine community should consider adopting a standardized process for conducting the PPE to protect all parties. Recommendations Recommendations are provided to equip the sports medicine community with the tools necessary to conduct the PPE as effectively and efficiently as possible using available scientific evidence and best practices. In addition, the recommendations will help clinicians identify those conditions that may threaten the health and safety of participants in organized sports, may require further evaluation and intervention, or may result in potential disqualification.

Athletes with seizure disorders.

PubMed

Knowles, Byron Don; Pleacher, Michael D

2012-01-01

Individuals with seizure disorders have long been restricted from participation in certain sporting activities. Those with seizure disorders are more likely than their peers to have a sedentary lifestyle and to develop obesity. Regular participation in physical activity can improve both physical and psychosocial outcomes for persons with seizure disorders. Seizure activity often is reduced among those patients who regularly engage in aerobic activity. Recent literature indicates that the diagnosis of seizure disorders remains highly stigmatizing in the adolescent population. Persons with seizure disorders may be more accepted by peer groups if they are allowed to participate in sports and recreational activities. Persons with seizure disorders are encouraged to participate in regular aerobic activities. They may participate in team sports and contact or collision activities provided that they utilize appropriate protective equipment. There seems to be no increased risk of injury or increasing seizure activity as the result of such participation. Persons with seizure disorders still are discouraged from participating in scuba diving and skydiving. The benefits of participation in regular sporting activity far outweigh any risk to the athlete with a seizure disorder who chooses to participate in sports.

Sport medicine and the ethics of boxing.

PubMed

Leclerc, S; Herrera, C D

1999-12-01

In the light of medical evidence of the health risks associated with boxing, a watchful agnostic position among sport physicians is no longer justifiable. The normal activity in a boxing match places the athletes at risk of head injury, some of which may be difficult to detect and impossible to repair. This suggests that sport physicians and others expert in the prevention and diagnosis of such injuries should take a public stand against boxing, as other medical associations have. Although there is a need for continuing research into the health risks, doctors can in the interim take steps to increase public awareness of these risks. Sport physicians in particular can make a strong public statement by also ending their professional involvement with boxing. This need not be interpreted as paternalism; doctors are qualified neither to make laws nor to restrict private behaviour. Sport physicians are, however, well equipped to advise those who do make laws and those who choose to engage in boxing. In the end, because this stance against boxing will probably reduce the number of brain injuries in certain athletes, autonomy will be preserved, rather than restricted.

Applying systems ergonomics methods in sport: A systematic review.

As sports systems become increasingly more complex, competitive, and technology-centric, there is a greater need for systems ergonomics methods to consider the performance, health, and safety of athletes in context with the wider settings in which they operate. Therefore, the purpose of this systematic review was to identify and critically evaluate studies which have applied a systems ergonomics research approach in the context of sports performance and injury management. Five databases (PubMed, Scopus, ScienceDirect, Web of Science, and SPORTDiscus) were searched for the dates 01 January 1990 to 01 August 2017, inclusive, for original peer-reviewed journal articles and conference papers. Reported analyses were underpinned by a recognised systems ergonomics method, and study aims were related to the optimisation of sports performance (e.g. communication, playing style, technique, tactics, or equipment), and/or the management of sports injury (i.e. identification, prevention, or treatment). A total of seven articles were identified. Two articles were focussed on understanding and optimising sports performance, whereas five examined sports injury management. The methods used were the Event Analysis of Systemic Teamwork, Cognitive Work Analysis (the Work Domain Analysis Abstraction Hierarchy), Rasmussen's Risk Management Framework, and the Systems Theoretic Accident Model and Processes method. The individual sport application was distance running, whereas the team sports contexts examined were cycling, football, Australian Football League, and rugby union. The included systems ergonomics applications were highly flexible, covering both amateur and elite sports contexts. The studies were rated as valuable, providing descriptions of injury controls and causation, the factors influencing injury management, the allocation of responsibilities for injury prevention, as well as the factors and their interactions underpinning sports performance. Implications and future directions for research are described. Copyright © 2018 Elsevier Ltd. All rights reserved.

Ice samples, after sliding against a steel runner, show evidence of recrystallization and microcracking under the runner, as well as macroscopic cracking throughout the ice. The experiments that produced these ice samples are designed to be analogous to sliding in the winter sport of skeleton. Changes in the ice fabric are shown using thick and thin sections under both diffuse and polarized light. Ice drag is estimated as 40-50% of total energy dissipation in a skeleton run. The experimental results are compared with visual inspections of skeleton tracks, and to similar behaviour in rocks during sliding on earthquake faults. The results presented may be useful to athletes and designers of winter sports equipment.This article is part of the themed issue 'Microdynamics of ice'. © 2016 The Author(s).

Evaluation and management of sport-related concussions in adolescent athletes

PubMed Central

Parachuri, Venu; Shettigar, Amrith

2017-01-01

Sport-related concussions in young athletes are common, generally under reported and often go unrecognized. Concussion in sport may result either from a direct impact to the head or from indirect forces transmitted to the brain from impact elsewhere on the body. Concussions may also result from sudden acceleration, deceleration or rotational forces to the brain. The key features of concussion include confusion, impaired memory and reduced speed of information processing. Recovery may occur from a few days to several weeks or months. Both physical and cognitive rests are recommended for recovery. Long-term cognitive and behavioral complications are a concern. Preventive strategies include education, modification of sport rules, use of equipment such as headgears, face masks and mouth guards, and neck muscle training. Evidence is limited to support effectiveness of these preventive measures with the exception of rule modification in some sports. Laws have been enacted that require medical evaluation and clearance prior to return to play; however, evidence thus far does not show that laws have been effective in reducing the incidence of concussions in sport. More research is needed in all areas of preventive measures. Sports participation is a complex personal decision on the part of adolescent and his or her family. They should be provided with all information on inherent risks so that they can make an informed decision. PMID:28795001

What are the exercise-based injury prevention recommendations for recreational alpine skiing and snowboarding? A systematic review.

PubMed

Hébert-Losier, Kim; Holmberg, Hans-Christer

2013-05-01

Skiing and snowboarding are two activities that significantly contribute to the total number of sports-related injuries reported per year. Strength, endurance and cardiovascular fitness are central components in sports injury prevention. Providing exercises and training recommendations specific to recreational skiers and snowboarders is important in both injury prevention and reducing the prevalence and cost associated with alpine winter sports injuries. The aim of this paper was to systematically review the literature for injury prevention recommendations specific to recreational alpine skiers and snowboarders. The focus was to discern recommendations that targeted physical fitness, exercise and/or training in the prevention of musculoskeletal injuries in these two sports. Fourteen electronic databases were searched in October 2011 using relevant MeSH terms and key words. Articles were included if they addressed injury prevention, recreational alpine skiing or snowboarding and musculoskeletal injuries. Only original research articles published in peer-reviewed journals, and in the English-language, were reviewed. Articles on elite athletes were excluded. Two independent reviewers quality assessed articles meeting inclusion criteria using a modified version of the Downs and Black Quality Assessment Checklist. Data on study population, study design, study location and injury prevention recommendation(s) were extracted from articles using a standard form and subsequently categorized to facilitate data synthesis. A total of 30 articles met the inclusion criteria and were reviewed, having an average ± standard deviation quality score of 72% ± 17% (range: 23-100 %). Overall, 80 recommendations for the prevention of musculoskeletal injuries in recreational alpine skiers and snowboarders were identified and classified into five main groups: equipment (n = 24), education and knowledge (n = 11), awareness and behaviour (n = 15), experience (n = 10) and third-party involvement (n = 20). No recommendations pertained to physical fitness, exercise and/or training per se, or its role in preventing injury. A comprehensive meta-analysis was not possible because several articles did not report data in sufficient detail. The importance of targeting physical fitness in injury prevention is accepted in sports medicine and rehabilitation; yet, there was a paucity of articles included in this review that explicitly investigated this aspect with regards to recreational alpine skiing and snowboarding. The most frequent recommendations for preventing skiing and snowboarding injuries concerned equipment or the involvement of third parties. The dominance of equipment-related measures in the injury prevention literature may be rationalized from a sports biomechanics viewpoint, as these activities involve high velocities and impact forces. Nonetheless, this also indicates a need for appropriate levels of strength, endurance and conditioning to meet the technical demands of these sports. Bearing this in mind, future research is encouraged to investigate the role of physical fitness, exercise and training in decreasing the incidence and severity of skiing and snowboarding injuries in recreational athletes.

Based on two clinical observations of adverse reactions during exercise with latex sport bands, we aimed to assess the possible risk for allergic patients posed by this equipment by investigating allergen content and IgE binding potential. Protein extracts of three different latex sport bands were characterized with sera of latex allergic patients. The IgE recognition profile of the allergic patients was identified by component resolved diagnosis and the allergen composition of the extracts was characterized by inhibition assays with the recombinant latex allergens Hev b 1, 3, 5, 6.02, and 8. The sera showed pronounced IgE binding to all three blotted extracts, however with diverse patterns. Inhibition assays revealed the presence of Hev b 1, 3, 5, and 8 in latex sport band extracts. The clinical relevance of contained allergens was demonstrated by strong skin reactions when testing with latex sport bands. From our results we conclude that latex sport bands contain clinically relevant allergens and may cause latex allergic individuals to experience allergic symptoms, potentially amplified by exercise-induced mechanisms. Even though latex is labeled on products, it is important that patients as well as athletic trainers and physical therapists recognize the risk of adverse reactions with these bands.

Managing an airway in an unconscious athlete is a lifesaving skill that may be made more difficult by the recent changes in protective equipment. Different airway maneuvers and techniques may be required to help ventilate an unconscious athlete who is wearing full protective equipment. To assess the effectiveness of different airway maneuvers with football, ice hockey, and soccer players wearing full protective equipment. Crossover study. University sports medicine clinic. A total of 146 university varsity athletes, consisting of 62 football, 45 ice hockey, and 39 soccer players. Athletes were assessed for different airway and physical characteristics. Three investigators then evaluated the effectiveness of different bag-valve-mask (BVM) ventilation techniques in supine athletes who were wearing protective equipment while inline cervical spine immobilization was maintained. The effectiveness of 1-person BVM ventilation (1-BVM), 2-person BVM ventilation (2-BVM), and inline immobilization and ventilation (IIV) was judged by each investigator for each athlete using a 4-point rating scale. All forms of ventilation were least difficult in soccer players and most difficult in football players. When compared with 1-BVM, both 2-BVM and IIV were deemed more effective by all investigators for all athletes. Interference from the helmet and stabilizer were common reasons for difficult ventilation in football and ice hockey players. Sports medicine professionals should practice and be comfortable with different ventilation techniques for athletes wearing full equipment. The use of a new ventilation technique, termed inline immobilization and ventilation, may be beneficial, especially when the number of responders is limited.

Social individualism: Walter Gropius and his appropriation of Franz Müller-Lyer's idea of a new man.

PubMed

Poppelreuter, Tanja

2011-01-01

In 1929, Walter Gropius developed the "High-Rise Steel Frame Apartment Building" that was based on theories about the emergence of a New Man put forward by sociologist Franz Müller-Lyer. In his lecture at the Congrès International d’Architecture Moderne conference in 1929, Gropius appropriated Müller-Lyer's sociology in order to promote and prompt the re-development of high-rise tenements and master households. Gropius’ 1931 contribution to the Deutsche Bauausstellung in Berlin incorporated a full-scale community lounge and a recreation area with sporting equipment, as well as a model and plans for a "High-Rise Steel Frame Apartment Building" that were designed in accordance with Müller-Lyer's theories. While it shows Müller-Lyer's influence, the boxing equipment found in the recreation area reflects the importance that sport, and boxing in particular, had gained after 1900. Boxing was perceived as a sport that would not only further fitness but also raise the spirits and help the inhabitant to succeed in the modern urban environment. By providing boxing equipment, Müller-Lyer's vision, which envisaged master households as furthering a community of peaceful individuals living in a condition of mutual trust, is weakened. In 1923, the sociologist Helmuth Plessner had regarded utopian visions of ideal communities as antithesis to actual events in the Weimar Republic. The embracing of theories that promised an evolutionary and linear development towards peaceful communities can be regarded as a counterreaction to a present that was perceived as an imperfect and temporary condition. Furthermore, Gropius’ appropriation of Müller-Lyer's sociology not only helped to distinguish his position from Marxist and socialist theories but also illustrated the contemporary tendency to accept utopian ideas while simultaneously doubting the practicality of some.

Mixed martial arts: injury patterns and issues for the ringside physician.

PubMed

Seidenberg, Peter H

2011-01-01

Mixed martial arts (MMA) is a fast-growing combat sport. There are limited studies investigating MMA's injury incidence. However, from the data available, closed head injuries and lacerations commonly are experienced by competitors. Sanctioned events require the presence of ringside physicians, who should be well versed in handling these types of injuries. Additionally, sports-medicine providers should have an appropriately equipped medical bag, and before providing coverage, they need to coordinate with emergency medical personnel in order to more efficiently deliver care if urgent situations arise. More research is needed on injury incidence and prevention in MAA.

The elite young athlete: strategies to ensure physical and emotional health

PubMed Central

Sabato, Todd M; Walch, Tanis J; Caine, Dennis J

2016-01-01

This article presents a current review of the risk of physical and psychological injury associated with participation in elite youth sport, and suggests strategies to ensure the physical and emotional health of these young athletes. Although there is lack of epidemiological data, especially with regard to psychological injury, preliminary data suggest that the risk of injury is high in this population. While there is lack of incident and follow-up data, there is also concern regarding burnout, disordered eating, and the long-term consequences of injury. Modifiable injury risk factors identified include postural control, competition anxiety, life events, previous injury, and volume of training. There are presently no studies designed to determine the effectiveness of injury prevention measures in elite youth sports. However, there is adequate evidence arising from injury prevention studies of youth sports participants – including neuromuscular training, protective equipment, mental training to enhance self-esteem, and sport rules modification – to prevent injuries in elite youth sports settings. Although not tested, psychosocial prevention strategies such as adoption of task-oriented coping mechanisms, autonomous support from parents, and a proactive organizational approach also show promise in injury prevention.

Sport medicine and the ethics of boxing

PubMed Central

Leclerc, S.; Herrera, C. D.

1999-01-01

In the light of medical evidence of the health risks associated with boxing, a watchful agnostic position among sport physicians is no longer justifiable. The normal activity in a boxing match places the athletes at risk of head injury, some of which may be difficult to detect and impossible to repair. This suggests that sport physicians and others expert in the prevention and diagnosis of such injuries should take a public stand against boxing, as other medical associations have. Although there is a need for continuing research into the health risks, doctors can in the interim take steps to increase public awareness of these risks. Sport physicians in particular can make a strong public statement by also ending their professional involvement with boxing. This need not be interpreted as paternalism; doctors are qualified neither to make laws nor to restrict private behaviour. Sport physicians are, however, well equipped to advise those who do make laws and those who choose to engage in boxing. In the end, because this stance against boxing will probably reduce the number of brain injuries in certain athletes, autonomy will be preserved, rather than restricted.

2016-01-01

Paralympic sport provides sporting opportunities for athletes with a disability, with the Paralympic Games as the main event. Participation in sport is, however, associated with a significant risk for sustaining injuries and illnesses. Our knowledge of sports-related injuries and illnesses in Paralympic sport is very limited and there are no large-scale epidemiological cohort studies. The purpose here is to present a protocol for a prospective longitudinal study: The Sports-Related Injuries and Illnesses in Paralympic Sport Study (SRIIPSS). An argument-based method for investigation of design problems was used to structure the study protocol. The primary requirement of the protocol is to allow prospective studies over time and include exposure to both training and competition. To reflect the complexity of Paralympic sport with athletes' pre-existing impairments, use of assistive equipment, pain and other and medical issues, it is required that the data collection system is specifically adapted to Paralympic sport. To allow the collection of data, at the same time as there is limited access to coaches and medical personnel, it is advantageous that data can be collected online directly from the athletes. Based on this a self-report athlete monitoring system will be developed, where the athletes can enter data weekly via their mobile phones or lap-tops. Data will be collected from around 100 Swedish Paralympic athletes for approximately 1 year, which will allow us to i) prospectively estimate the annual incidence of sports-related injuries and illnesses and ii) explore risk factors and mechanisms for sustaining sports-related injuries and illnesses based on athlete exposure and training loads. For effective implementation of injury and illness prevention measures, comprehensive epidemiological knowledge is required. This study will be the first prospective longitudinal self-report study of sports-related injuries and illnesses in Paralympic sport over a longer period of time. The results will eventually contribute to the development of evidence-based preventive measures specifically adapted to Paralympic sport in order to provide safe and healthy sport participation. Thereby, the project will be of relevance for Paralympic athletes at all levels and to the Paralympic Movement. The study is registered at ClinicalTrials.gov (Identifier: NCT02788500; Registration date: 22 May 2016).

Few prospective studies have examined predictors of change in specific physical activity (PA) behaviours in different ethnic groups. To assess predictors of change in sports participation in Latino and non-Latino 5-8 year-old children in San Diego, California. Average sports participation frequency (days/week) was assessed by validated parent-report at baseline (Nov 2006-May 2008) and 1 year later in 541 children (45.0% male, 41.1% Latino; mean ± SD age: 6.6 ± 0.7 years) taking part in an obesity prevention study (Project MOVE). Biological (sex, age, Body Mass Index z-score), socio-cultural (ethnicity, income, care giver education), parental (PA rules, PA encouragement) and environmental factors (home PA equipment, PA location) were assessed at baseline. Associations between change in sports participation and potential predictors were studied using multilevel linear regression stratified by Latino ethnicity, adjusted for sex, baseline sport participation, study condition and recruitment area. Sports participation increased over 1 year (mean change: +0.5 days; p<0.001) and change was similar for boys and girls (p=0.95), but Latino children showed a greater increase (p=0.03). The number of locations used for PA (p=0.024) and the total frequency of PA location use (p=0.018) were positively associated with increased sports participation among Latinos. No predictors were identified for non-Latino children. Only factors relating to PA location were identified as predictors of change in sports participation for Latino children. Interventions targeting specific PA behaviours such as sports participation may need to consider PA locations for Latino children and be tailored for specific ethnic groups.

Fluid Balance in Team Sport Athletes and the Effect of Hypohydration on Cognitive, Technical, and Physical Performance.

PubMed

Nuccio, Ryan P; Barnes, Kelly A; Carter, James M; Baker, Lindsay B

2017-10-01

Sweat losses in team sports can be significant due to repeated bursts of high-intensity activity, as well as the large body size of athletes, equipment and uniform requirements, and environmental heat stress often present during training and competition. In this paper we aimed to: (1) describe sweat losses and fluid balance changes reported in team sport athletes, (2) review the literature assessing the impact of hypohydration on cognitive, technical, and physical performance in sports-specific studies, (3) briefly review the potential mechanisms by which hypohydration may impact team sport performance, and (4) discuss considerations for future directions. Significant hypohydration (mean body mass loss (BML) >2%) has been reported most consistently in soccer. Although American Football, rugby, basketball, tennis, and ice hockey have reported high sweating rates, fluid balance disturbances have generally been mild (mean BML <2%), suggesting that drinking opportunities were sufficient for most athletes to offset significant fluid losses. The effect of hydration status on team sport performance has been studied mostly in soccer, basketball, cricket, and baseball, with mixed results. Hypohydration typically impaired performance at higher levels of BML (3-4%) and when the method of dehydration involved heat stress. Increased subjective ratings of fatigue and perceived exertion consistently accompanied hypohydration and could explain, in part, the performance impairments reported in some studies. More research is needed to develop valid, reliable, and sensitive sport-specific protocols and should be used in future studies to determine the effects of hypohydration and modifying factors (e.g., age, sex, athlete caliber) on team sport performance.

2010-02-01

Using continuous two wavelength near-infrared technology to detect the variation in the consistency of oxygen hemoglobin in the muscle and the sports heart rate wireless real time collection technology, we devised the real time muscle tissue oxygenation and instantaneous heart rate experiment scheme and implemented it for the process of the 100 m run with two parameters given simultaneously. The experiment shows that the concentration of the oxygen hemoglobin in the muscle tissue continues decreasing after the end of the 100 m run, and the time interval between the moment when the concentration of the oxygen hemoglobin attains the minimum value and the moment when the athletes finish the 100 m run is (6.65 +/- 1.10) sec; while the heart rate continues increasing after the end of the 100 m run, and the time interval between the moment when the heart rate attains the maximum value and the moment when the athletes finish the 100 m run is (8.00 +/- 1.57) sec. The results show that the two wavelength near-infrared tissue oxygenation detection technology and the sports heart rate real time collection equipment can accurately measure the sports tissue oxygenation and the heart rate in the extreme intensity sport, and reveal the process of muscle oxygen transportation and consumption and its dynamic character with the heart rate in the extreme intensity sport.

2017-01-01

Background: Foot and ankle injuries are common in sports, particularly in cleated athletes. Traditionally, the athletic shoe has not been regarded as a piece of protective equipment but rather as a part of the uniform, with a primary focus on performance and subjective feedback measures of comfort. Changes in turf and shoe design have poorly understood implications on the health and safety of players. Evidence Acquisition: A literature search of the MEDLINE and PubMed databases was conducted. Keywords included athletic shoewear, cleated shoe, football shoes, and shoewear, and search parameters were between the years 2000 and 2016. Study Design: Clinical review. Level of Evidence: Level 5. Results: The athletic shoe is an important piece of protective sports equipment. There are several important structural considerations of shoe design, including biomechanical compliance, cleat and turf interaction, and shoe sizing/fit, that affect the way an athlete engages with the playing surface and carry important potential implications regarding player safety if not understood and addressed. Conclusion: Athletic footwear should be considered an integral piece of protective equipment rather than simply an extension of the uniform apparel. More research is needed to define optimal shoe sizing, the effect that design has on mechanical load, and how cleat properties, including pattern and structure, interact with the variety of playing surfaces.

Abstract Context: Managing an airway in an unconscious athlete is a lifesaving skill that may be made more difficult by the recent changes in protective equipment. Different airway maneuvers and techniques may be required to help ventilate an unconscious athlete who is wearing full protective equipment. Objective: To assess the effectiveness of different airway maneuvers with football, ice hockey, and soccer players wearing full protective equipment. Design: Crossover study. Setting: University sports medicine clinic. Patients or Other Participants: A total of 146 university varsity athletes, consisting of 62 football, 45 ice hockey, and 39 soccer players. Intervention(s): Athletes were assessed for different airway and physical characteristics. Three investigators then evaluated the effectiveness of different bag-valve-mask (BVM) ventilation techniques in supine athletes who were wearing protective equipment while inline cervical spine immobilization was maintained. Main Outcome Measure(s): The effectiveness of 1-person BVM ventilation (1-BVM), 2-person BVM ventilation (2-BVM), and inline immobilization and ventilation (IIV) was judged by each investigator for each athlete using a 4-point rating scale. Results: All forms of ventilation were least difficult in soccer players and most difficult in football players. When compared with 1-BVM, both 2-BVM and IIV were deemed more effective by all investigators for all athletes. Interference from the helmet and stabilizer were common reasons for difficult ventilation in football and ice hockey players. Conclusions: Sports medicine professionals should practice and be comfortable with different ventilation techniques for athletes wearing full equipment. The use of a new ventilation technique, termed inline immobilization and ventilation, may be beneficial, especially when the number of responders is limited. PMID:21391796

The purpose of this study was to determine the characteristics of individuals who participate in the National Veterans Wheelchair Games (NVWG) and the Winter Sports Clinic (WSC) for veterans with disabilities. In addition, it was of interest to determine how these events had impacted their lives. Participants were recruited at the 20th Winter Sports Clinic, held in Snowmass Colorado and the 26th National Veterans Wheelchair Games held in Anchorage, Alaska. Data of interest included demographic, sport participation information, community integration, self-esteem, and quality of life. A secondary data analysis was completed to determine how comparable individuals who attended the NVWG/WSC were to individuals who did not participate in these events. The 132 participants were a mean age of 47.4 + 13.4 and lived with a disability for an average of 13.4 + 12.1. Participants felt that the NVWG/WSC increased their knowledge of sports equipment (92%), learning sports (89%), mobility skills (84%), and acceptance of disability (84%). The majority of participants stated that the NVWG/WSC improved their life. Of those who participated at the NVWG/WSC, they tended to be more mobile, but have increased physical and cognitive limitations as measured by the CHART when compared to the non-attendees. Recommending veterans participate in events such as the NVWG and WSC can provide psychosocial benefits to veterans with disabilities.

Policy statement—Climatic heat stress and exercising children and adolescents.

PubMed

Bergeron, Michael F; Devore, Cynthia; Rice, Stephen G

2011-09-01

Results of new research indicate that, contrary to previous thinking, youth do not have less effective thermoregulatory ability, insufficient cardiovascular capacity, or lower physical exertion tolerance compared with adults during exercise in the heat when adequate hydration is maintained. Accordingly, besides poor hydration status, the primary determinants of reduced performance and exertional heat-illness risk in youth during sports and other physical activities in a hot environment include undue physical exertion, insufficient recovery between repeated exercise bouts or closely scheduled same-day training sessions or rounds of sports competition, and inappropriately wearing clothing, uniforms, and protective equipment that play a role in excessive heat retention. Because these known contributing risk factors are modifiable, exertional heat illness is usually preventable. With appropriate preparation, modifications, and monitoring, most healthy children and adolescents can safely participate in outdoor sports and other physical activities through a wide range of challenging warm to hot climatic conditions.

Sex equity in French newspaper photographs: A content analysis of 2012 Olympic Games by L'Equipe.

PubMed

Delorme, Nicolas; Testard, Nadège

2015-01-01

The aim of this article was to examine sex equity in the photographic coverage of the London 2012 Olympic Games by a French sports daily newspaper. A sample of 1073 photographs was collected and analysed. A content analysis was carried out focusing on the number of photographs, the space they cover, their location and position, the type and colour of shot and the sport they depict. A significant under-representation of female athletes' photographs was found. However, contrary to most of previous research in this field, the other quantitative and qualitative variables do not show any differences. Furthermore, a significant positive correlation between the number of photographs for each sport and the number of French medals was found (for women, for men and for the whole sample), suggesting that the photographic coverage of this event is mainly based on the success of French athletes independently of their sex.

Physics of Sports: Resonances

NASA Astrophysics Data System (ADS)

Browning, David

2000-04-01

When force is applied by an athlete to sports equipment resonances can occur. Just a few examples are: the ringing of a spiked volleyball, the strumming of a golf club shaft during a swing, and multiple modes induced in an aluminum baseball bat when striking a ball. Resonances produce acoustic waves which, if conditions are favorable, can be detected off the playing field. This can provide a means to evaluate athletic performance during game conditions. Results are given from the use of a simple hand-held acoustic detector - by a spectator sitting in the stands - to determine how hard volleyballs were spiked during college and high school games.

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.

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

PubMed

Russell, Mark; West, Daniel J; Harper, Liam D; Cook, Christian J; Kilduff, Liam P

2015-03-01

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.

Organized Sports and Unstructured Active Play as Physical Activity Sources in Children From Low-Income, Chicago Households.

PubMed

Appelhans, Bradley M; Li, Hong

2016-08-01

This study tested associations of organized sports participation and unstructured active play with overall moderate and vigorous physical activity (MVPA) in low-income children and examined factors associated with participation frequency. Research staff visited 88 low-income Chicago households with children ages 6-13 years. MVPA was assessed through 7-day accelerometry. Researchers documented the home availability of physical activity equipment. Caregivers reported on child participation in organized sports and unstructured active play, family support for physical activity, perceived neighborhood safety, and access to neighborhood physical activity venues. Despite similar participation in organized sports and unstructured active play, boys accumulated more MVPA than girls. MVPA was predicted by an interaction between gender and unstructured active play. Boys accumulated 23-45 additional minutes of weekday MVPA and 53-62 additional minutes of weekend MVPA through unstructured active play, with no such associations in girls. Higher reported neighborhood safety and family support for physical activity were associated with engagement in unstructured active play for both genders, and with participation in organized sports for girls. Physical activity interventions for low-income, urban children should emphasize unstructured active play, particularly in boys. Fostering family support for physical activity and safe play environments may be critical intervention components.

2006-04-11

Sports sponsorship is a significant marketing tool. As such, it can promote products that pose risks to health (eg, high fat and high sugar foods) or it can promote health-supporting products (eg, sporting equipment and services). However, there is a lack of data on the proportion of sponsorship associated with "unhealthy" and "healthy" products and no methodology for systematically assessing it. This research aimed to explore this proportion with an Internet survey of sports sponsorship in the New Zealand setting. A search methodology was developed to identify Internet-based evidence of sports sponsorship at the national level and at the regional and club level in one specific region (Wellington). The top eight sports for 5-17-year-olds were selected and products and services of sponsors were classified in terms of potential public health impact (using a conservative approach). Sponsorship of these popular sports was common at the national, regional and club levels (640 sponsors listed on 107 websites overall). Sports sponsorship associated with sponsors' products classified as "unhealthy" (eg, food high in fat and sugar, gambling and alcohol) were over twice as common as sponsorship associated with sponsors' products classified as "healthy" (32.7% (95% CI = 29.1, 36.5) versus 15.5% (95% CI = 12.8, 18.6) respectively). "Gambling" was the most common specific type of sponsorship (18.8%) followed by alcohol (11.3%). There were significantly more "alcohol" sponsors for rugby, compared to all the other sports collectively (rate ratio (RR) = 2.47; 95% CI = 1.60, 3.79), and for top male sports compared to female (RR = 1.83; 95% CI = 1.05, 3.18). Also there was significantly more "unhealthy food" sponsorship for touch rugby and for "junior" teams/clubs compared to other sports collectively (RR = 6.54; 95% CI = 2.07, 20.69; and RR = 14.72, 95% CI = 6.22, 34.8; respectively). A validation study gave an inter-rater reliability for number of sponsors of 95% (n = 87 sponsors), and an inter-rater reliability of classification and categorisation of 100%. This study found that the sponsorship of popular sports for young people is dominated by "unhealthy" sponsorship (ie, predominantly gambling, alcohol and unhealthy food) relative to "healthy" sponsorship. Governments may need to consider regulations that limit unhealthy sponsorship and/or adopt alternative funding mechanisms for supporting popular sports.

The Use of Wearable Microsensors to Quantify Sport-Specific Movements.

Chambers, Ryan; Gabbett, Tim J; Cole, Michael H; Beard, Adam

2015-07-01

Microtechnology has allowed sport scientists to understand the locomotor demands of various sports. While wearable global positioning technology has been used to quantify the locomotor demands of sporting activities, microsensors (i.e. accelerometers, gyroscopes and magnetometers) embedded within the units also have the capability to detect sport-specific movements. The objective of this study was to determine the extent to which microsensors (also referred to as inertial measurement units and microelectromechanical sensors) have been utilised in quantifying sport-specific movements. A systematic review of the use of microsensors and associated terms to evaluate sport-specific movements was conducted; permutations of the terms used included alternate names of the various technologies used, their applications and different applied environments. Studies for this review were published between 2008 and 2014 and were identified through a systematic search of six electronic databases: Academic Search Complete, CINAHL, PsycINFO, PubMed, SPORTDiscus, and Web of Science. Articles were required to have used athlete-mounted sensors to detect sport-specific movements (e.g. rugby union tackle) rather than sensors mounted to equipment and monitoring generic movement patterns. A total of 2395 studies were initially retrieved from the six databases and 737 results were removed as they were duplicates, review articles or conference abstracts. After screening titles and abstracts of the remaining papers, the full text of 47 papers was reviewed, resulting in the inclusion of 28 articles that met the set criteria around the application of microsensors for detecting sport-specific movements. Eight articles addressed the use of microsensors within individual sports, team sports provided seven results, water sports provided eight articles, and five articles addressed the use of microsensors in snow sports. All articles provided evidence of the ability of microsensors to detect sport-specific movements. Results demonstrated varying purposes for the use of microsensors, encompassing the detection of movement and movement frequency, the identification of movement errors and the assessment of forces during collisions. This systematic review has highlighted the use of microsensors to detect sport-specific movements across a wide range of individual and team sports. The ability of microsensors to capture sport-specific movements emphasises the capability of this technology to provide further detail on athlete demands and performance. However, there was mixed evidence on the ability of microsensors to quantify some movements (e.g. tackling within rugby union, rugby league and Australian rules football). Given these contrasting results, further research is required to validate the ability of wearable microsensors containing accelerometers, gyroscopes and magnetometers to detect tackles in collision sports, as well as other contact events such as the ruck, maul and scrum in rugby union.

Football injuries: current concepts.

PubMed

Olson, David E; Sikka, Robby Singh; Hamilton, Abigail; Krohn, Austin

2011-01-01

Football is one of the most popular sports in the United States and is the leading cause of sports-related injury. A large focus in recent years has been on concussions, sudden cardiac death, and heat illness, all thought to be largely preventable health issues in the young athlete. Injury prevention through better understanding of injury mechanisms, education, proper equipment, and practice techniques and preseason screening may aid in reducing the number of injuries. Proper management of on-field injuries and health emergencies can reduce the morbidity associated with these injuries and may lead to faster return to play and reduced risk of future injury. This article reviews current concepts surrounding frequently seen football-related injuries.

Regulations permitting the sport of paragliding were issued on April 15, 1987 by the Department of Transportation in Germany. With the rising number participants in this sport, the number of reported injuries has also been steadily increasing. The herein reported epidemiologic study presents the incidence, localization and degree of injuries associated with this sport documented in Germany, Austria and Switzerland. During the period from 1. 1. 1987 until 31. 12. 1989, 218 injuries associated with paragliding were reported in the above mentioned countries. 181 occurred during landing, 28 during start procedures and 9 during flight. The average age of the patients was 29.6 years. The analysis of the localization of the trauma related injury documented 33.9% spinal injuries, 13.8% injuries of the upper extremities and 41.3% of the lower extremities. Over half of these injuries were treated surgically and in 54 instances permanent disability remained. In the sport of paragliding the lower extremities are at greatest risk for injury during the landing phase. Proper equipment especially sturdy shoes, exact training in landing techniques and especially improved instruction in procedures during aborted or crash landings of the individual paraglider is required to reduce the frequency of these injuries.

Introduction into the Virtual Olympic Games Framework for online communities.

Stoilescu, Dorian

2009-06-01

This paper presents the design of the Virtual Olympic Games Framework (VOGF), a computer application designated for athletics, health care, general well-being, nutrition and fitness, which offers multiple benefits for its participants. A special interest in starting the design of the framework was in exploring how people can connect and participate together using existing computer technologies (i.e. gaming consoles, exercise equipment with computer interfaces, devices of measuring health, speed, force and distance and Web 2.0 applications). A stationary bike set-up offering information to users about their individual health and athletic performances has been considered as a starting model. While this model is in the design stage, some preliminary findings are encouraging, suggesting the potential for various fields: sports, medicine, theories of learning, technologies and cybercultural studies. First, this framework would allow participants to perform a variety of sports and improve their health. Second, this would involve creating an online environment able to store health information and sport performances correlated with accessing multi-media data and research about performing sports. Third, participants could share experiences with other athletes, coaches and researchers. Fourth, this framework also provides support for the research community in their future investigations.

Learning a sports skill is a complex process in which practitioners are challenged to cater for individual differences. The main purpose of this study was to explore the effectiveness of a Nonlinear Pedagogy approach for learning a sports skill. Twenty-four 10-year-old females participated in a 4-week intervention involving either a Nonlinear Pedagogy (i.e.,manipulation of task constraints including equipment and rules) or a Linear Pedagogy (i.e., prescriptive, repetitive drills) approach to learn a tennis forehand stroke. Performance accuracy scores, movement criterion scores and kinematic data were measured during pre-intervention, post-intervention and retention tests. While both groups showed improvements in performance accuracy scores over time, the Nonlinear Pedagogy group displayed a greater number of movement clusters at post-test indicating the presence of degeneracy (i.e., many ways to achieve the same outcome). The results suggest that degeneracy is effective for learning a sports skill facilitated by a Nonlinear Pedagogy approach. These findings challenge the common misconception that there must be only one ideal movement solution for a task and thus have implications for coaches and educators when designing instructions for skill acquisition.

In the present study we add to the literature by exploring the degree to which UK practitioner psychologists perceive themselves able to support sport coaches, and how professional training prepares psychologists for coach work across performance domains. Ten participants comprising seven sport and exercise psychologists with Health Care Professions Council (HCPC) practitioner psychologist status and three trainee psychologists studying towards the British Psychological Society (BPS) qualification in sport and exercise psychology (QSEP) were individually interviewed. All participants reported prior experience of working with coaches across all performance domains. We explored: practitioner's understanding of the challenges coaches face within their job; practitioner's experiences of coach work; perspectives about the ways in which practitioners could and should support coaches; and, the degree to which professional training prepares practitioners for coach work. Using recommended procedures of Connelly and Peltzer, content analysis revealed practitioners perceived the challenges faced by coaches are different at grassroots level compared to those working with elite athletes, and that practitioners require skills to provide one-to-one coach support and group-based interventions. All practitioners perceived that training programmes do not adequately equip trainees with skills required for coach work. We discuss the implications for enhancing practitioner training in the UK.

Physical activity prescription: a critical opportunity to address a modifiable risk factor for the prevention and management of chronic disease: a position statement by the Canadian Academy of Sport and Exercise Medicine.

PubMed

Thornton, Jane S; Frémont, Pierre; Khan, Karim; Poirier, Paul; Fowles, Jonathon; Wells, Greg D; Frankovich, Renata J

2016-09-01

Non-communicable disease is a leading threat to global health. Physical inactivity is a large contributor to this problem; in fact, the WHO ranks it as the fourth leading risk factor for overall morbidity and mortality worldwide. In Canada, at least 4 of 5 adults do not meet the Canadian Physical Activity Guidelines of 150 min of moderate-to-vigorous physical activity per week. Physicians play an important role in the dissemination of physical activity (PA) recommendations to a broad segment of the population, as over 80% of Canadians visit their doctors every year and prefer to get health information directly from them. Unfortunately, most physicians do not regularly assess or prescribe PA as part of routine care, and even when discussed, few provide specific recommendations. PA prescription has the potential to be an important therapeutic agent for all ages in primary, secondary and tertiary prevention of chronic disease. Sport and exercise medicine (SEM) physicians are particularly well suited for this role and should collaborate with their primary care colleagues for optimal patient care. The purpose of this Canadian Academy and Sport and Exercise Medicine position statement is to provide an evidence-based, best practices summary to better equip SEM and primary care physicians to prescribe PA and exercise, specifically for the prevention and management of non-communicable disease. This will be achieved by addressing common questions and perceived barriers in the field.Author note This position statement has been endorsed by the following nine sport medicine societies: Australasian College of Sports and Exercise Physicians (ACSEP), American Medical Society for Sports Medicine (AMSSM), British Association of Sports and Exercise Medicine (BASEM), European College of Sport & Exercise Physicians (ECOSEP), Norsk forening for idrettsmedisin og fysisk aktivite (NIMF), South African Sports Medicine Association (SASMA), Schweizerische Gesellschaft für Sportmedizin/Swiss Society of Sports Medicine (SGSM/SSSM), Sport Doctors Australia (SDrA), Swedish Society of Exercise and Sports Medicine (SFAIM), and CASEM.

Mouthguard BITES (Behavior, Impulsivity, Theory Evaluation Study): What Drives Mouthguard Use Among High School Basketball and Baseball/Softball Athletes

2017-01-01

Although mouthguards are effective, inexpensive, easy to use, and readily available, this form of protective equipment has been underutilized. “Impulsive delay discounting” (an index of impulsive behavior) among high school athletes may help explain their decision making regarding use of protective equipment such as mouthguards. We investigated the relationship between high school baseball, softball, and basketball players’ mouthguard use, impulsive delay discounting, and the precaution adoption process model (a behavior change theory). A convenience sample of boys’ and girls’ basketball and baseball/softball players at 21 high schools in the Greater Columbus, Ohio, metro area completed a self-administered survey that captured their demographic information, knowledge, attitudes, and beliefs regarding mouthguard use, impulsive delay discounting, and precaution adoption process model stage. We surveyed a total of 1636 students (55.9 % male, 43.8 % female, 0.3 % unknown). Only 12.3 % reported using a mouthguard either every time or sometimes during practice or competition. The primary reasons reported for not wearing mouthguards were they were not required to (65.3 %) and that the athletes could not breathe or talk while wearing one (61.5 %). These reasons were consistent across sex and sport. Most athletes reported that their coaches (87.3 %) and parents (64.5 %) had never talked to them about wearing a mouthguard. Lower precaution adoption process model stage was significantly associated with higher impulsivity (p < 0.001) and higher delayed discounting (p = 0.016) after adjusting for school, sport, and sex. Voluntary mouthguard use among high school athletes playing basketball and baseball/softball remains low despite the risk of dental injury in these sports. Effective, evidence-based, targeted, and tailored interventions to improve adolescent athletes’ use of mouthguards to prevent sports-related dental injuries should be based on the specific behavioral and social factors influencing each athlete’s decision making regarding use of mouthguards.

We surveyed a total of 1636 students (55.9 % male, 43.8 % female, 0.3 % unknown). Only 12.3 % reported using a mouthguard either every time or sometimes during practice or competition. The primary reasons reported for not wearing mouthguards were they were not required to (65.3 %) and that the athletes could not breathe or talk while wearing one (61.5 %). These reasons were consistent across sex and sport. Most athletes reported that their coaches (87.3 %) and parents (64.5 %) had never talked to them about wearing a mouthguard. Lower precaution adoption process model stage was significantly associated with higher impulsivity (p < 0.001) and higher delayed discounting (p = 0.016) after adjusting for school, sport, and sex. Voluntary mouthguard use among high school athletes playing basketball and baseball/softball remains low despite the risk of dental injury in these sports. Effective, evidence-based, targeted, and tailored interventions to improve adolescent athletes' use of mouthguards to prevent sports-related dental injuries should be based on the specific behavioral and social factors influencing each athlete's decision making regarding use of mouthguards.

Mountain biking injuries in children and adolescents.

Over the last decade, the sport of mountain biking has experienced extensive growth in youth participation. Due to the unpredictable nature of outdoor sport, a lack of rider awareness and increased participation, the number of injuries has unnecessarily increased. Many believe that the actual incidence of trauma in this sport is underestimated and is just the 'tip of the iceberg'. The most common mechanism of injury is usually attributed to downhill riding and forward falling. Although rare, this type of fall can result in serious cranial and thoraco-abdominal trauma. Head and neck trauma continue to be documented, often resulting in concussions and the possibility of permanent neurological sequelae. Upper limb injuries range from minor dermal abrasions, contusions and muscular strains to complex particular fracture dislocations. These are caused by attempting to arrest the face with an outstretched hand, leading to additional direct injury. Common overuse injuries include repeated compression from the handlebars and vibration leading to neurovascular complications in the hands. Along with reports of blunt abdominal trauma and lumbar muscle strains, lower extremity injuries may include various hip/pelvic/groin contusions, patellofemoral inflammation, and various muscle strains. The primary causes of mountain biking injuries in children and adolescents include overuse, excessive fatigue, age, level of experience, and inappropriate or improperly adjusted equipment. Additional factors contributing to trauma among this age group involve musculoskeletal immaturity, collisions and falls, excessive speed, environmental conditions, conditioning and fitness status of the rider, nonconservative behavioural patterns, and inadequate medical care. The limited available data restrict the identification and understanding of specific paediatric mountain biking injuries and injury mechanisms. Education about unnecessary risk of injury, use of protective equipment, suitable bikes and proper riding technique, coupled with attentive and proper behaviour, are encouraged to reduce unnecessary injury. This article provides information on the causation and risk factors associated with injury among young mountain bikers, and recommendations to minimize trauma and enhance optimal performance and long-term enjoyment in this outdoor sport.

Some applications of mathematics in golf.

PubMed

Otto, S R

2017-08-01

At its core, like many other sports, golf is a game of integers. The minimization of the number of strokes played is generally what determines the winner, whether each of these are associated with the shortest of putts or the longest of drives. The outcomes of these shots are influenced by very slight changes, but hopefully in a deterministic sense. Understanding the mechanics of golf necessitates the development of models and this is coupled more often than not to the use of statistics. In essence, the individual aspects of the sport can be modelled adequately via fairly simplistic models, but the presence of a human at one end of the kinematic chain has a significant impact on the variability of the entire process. In this paper, we will review some of the ways that mathematics has been used to develop the understanding of the physical processes involved in the sport, including some of the analysis which is exploited within the Equipment Rules. We will also discuss some of the future challenges.

The quality of training conditions affects sporting success, injuries and health. The aim of the work was to present the conditions during the preparations of Polish athletes for the Summer Paralympic Games 2004-2012. The study encompassed 271 paralympians: Athens (91), Beijing (89) and London (91), competing in 13 disciplines. The research was based on a two-part questionnaire by Kłodecka-Różalska adjusted for disabled sports, and was conducted one month before each PG. Part 1 contained 20 closed-ended questions regarding conditions during preparations, while Part 2 concerned socio-demographic and sports-related data. Three levels of conditions: good, satisfactory and poor, were identified. The analysis showed that while the relationships between the athletes were good in all the preparatory periods, the co-operation with the paralympic coaches worsened. The standards of accommodation, food and sports facilities lowered. Personal orthopaedic supply was satisfactory in London; personal sporting equipment was good at all PG. The quality of medical care was the highest in London. The co-operation with physicians, physiotherapists and massage therapists was satisfactory. Consultations with the dietician were sporadic and assessed as poor. Psychological consultations were rare but satisfactory in Beijing and London. Contacts with the mass media were poor at all PG. Although combining private life, work, and education with sport was satisfactory, it was increasingly difficult to manage, particularly before London. The conditions during preparations for the PG 2004-2012 varied. Improvement was noticed only in the quality of medical care and personal orthopaedic supply.

Imaging Interplanetary CMEs at Radio Frequency From Solar Polar Orbit

NASA Astrophysics Data System (ADS)

Wu, Ji; Sun, Weiying; Zheng, Jianhua; Zhang, Cheng; Wang, Chi; Wang, C. B.; Wang, S.

Coronal mass ejections (CMEs) are violent discharges of plasma and magnetic fields from the Sun's corona. They have come to be recognized as the major driver of physical conditions in the Sun-Earth system. Consequently, the detection of CMEs is important for un-derstanding and ultimately predicting space weather conditions. The Solar Polar Orbit Radio Telescope (SPORT) is a proposed mission to observe the propagation of interplanetary CMEs from solar polar orbit. The main payload (radio telescope) on board SPORT will be an in-terferometric imaging radiometer working at the meter wavelength band, which will follow the propagation of interplanetary CMEs from a distance of a few solar radii to near 1 AU from solar polar orbit. The SPORT spacecraft will also be equipped with a set of optical and in situ measurement instruments such as a EUV solar telescope, a solar wind plasma experiment, a solar wind ion composition instrument, an energetic particle detector, a wave detector, a mag-netometer and an interplanetary radio burst tracker. In this paper, we first describe the current shortage of interplanetary CME observations. Next, the scientific motivation and objectives of SPORT are introduced. We discuss the basic specifications of the main radio telescope of SPORT with reference to the radio emission mechanisms and the radio frequency band to be observed. Finally, we discuss the key technologies of the SPORT mission, including the con-ceptual design of the main telescope, the image retrieval algorithm and the solar polar orbit injection. Other payloads and their respective observation objectives are also briefly discussed. Key words: Interplanetary CMEs; Interferometric imaging; Solar polar orbit; Radiometer.

Rib stress fractures among rowers: a systematic review on return to sports, risk factors and prevention.

2016-06-01

Rib stress fractures (RSFs) are injuries frequently sustained by elite rowers with an injury rate of 8-16% over the course of a rowing career, resulting in negative effects on training and performance. For clinical management, the aim of this review was to describe time to return to sports, summarize potentially preventive measures and appraise the evidence on risk factors. A search strategy was performed in PubMed, SportDiscus, Web of Science and Embase till June 1st 2015. All studies were graded on their quality. The search resulted in 124 studies, of which 17 were included: Ten reported on return to sports, 17 reported on risk factors and nine on preventive measures. For return to sports, nine studies mentioned a loss of training of 4-6 weeks. The shortest period was one week and the longest 16 weeks. For risk factors, insufficient or conflicting evidence was found for changes in the training program, incorrect rowing technique, female gender, low bone mineral density, inadequate equipment, and training type. For prevention, gradual changes in the training program, alertness on the part of coaches and clinicians, and supplementation of diet and hormones are suggested as effective measures. However, no effect studies have been found. The main outcome of this review on RSFs is that little evidence is available on return to sports, risk factors and preventive measures. Coaches and clinicians should carefully guide and assist rowers suffering from RSFs in off training and in the subsequent training period to regain their pre-injury level.

Sex Differences in Common Sports Injuries.

Common sports injuries include bone stress injuries (BSIs), anterior cruciate ligament (ACL) injuries, and concussions. Less commonly recognized are the specific sex differences in epidemiology, risk factors, and outcomes of these conditions by sex. An understanding of these factors can improve their clinical management, from prescribing appropriate prehabilitation to guiding postinjury rehabilitation and return to play. This narrative review summarizes the sex differences in the diagnosis and management of BSIs, ACL injuries, and concussions. Although BSIs are more common in female athletes, risk factors for both sexes include prior injury and relative energy deficiency in sport (RED-S). Risk factors in female athletes include smaller calf girth, femoral adduction, and higher rates of loading. Female athletes are also at greater risk for developing ACL injuries in high school and college, but their injury rate is similar in professional sports. Increased lateral tibial slope, smaller ACL size, and suboptimal landing mechanics are additional risk factors more often present in female athletes. Male athletes are more likely to have ACL surgery and have a higher rate of return to sport. Concussions occur more commonly in female athletes; however, female athletes are also more likely to report concussions. Male athletes more commonly sustain concussion through contact with another player. Female athletes more commonly sustain injury from contact with playing equipment. Managing post-concussion symptoms is important, and female athletes may have prolonged symptoms. An understanding of the sex-specific differences in these common sports injuries can help optimize their prehabilitation and rehabilitation.

Determine the frequency of personal protective equipment (PPE) use in adolescent inline skaters, skateboarders, and snowboarders; explore factors influencing PPE use; identify factors that would influence use; and examine the association of high-risk behaviors and PPE use. Cross-sectional survey. Central/southeast Wisconsin. Participants 13-18 years-old. None. Independent variables = age, gender, sport. None. Dependent variables = PPE use, factors influencing use, and frequency of other high-risk behaviors. The mean age of 333 participiants was 14.9 years. Adolescents wore considerably less PPE than recommended. Inline skaters wore the most; snowboarders the least. The most common reasons adolescents wore PPE were parents, peers, and rule/requirement. Younger adolescents cited parents more often than older adolescents as a factor for PPE use. Discomfort and lack of perceived need were the most common reasons for nonuse. Sustaining/witnessing an accident was the most common reason that would convince adolescents to wear PPE. Almost half of adolescents reported nothing would convince them to wear PPE. Younger adolescents wore more PPE than older adolescents. An association was seen between PPE use in all sports and bicycle helmets. An inverse relationship was found for tobacco and helmet use among skaters, as well as alcohol and helmet use in skateboarders. Adolescents underuse PPE. PPE reinforcement by parents/peers, encouraging bike helmets, manufacturing more comfortable gear, educating adolescents, and instituting PPE requirements in public areas may increase compliance. This could lead to decreased injuries. Physicians should discuss PPE with their patients/families. There may be an association between PPE use in extreme sports and decreased high-risk health behaviors.

Getting the Public Excited about Science through News Stories about Global Sporting Events

News is all about opportunity, and no topic can pull an audience together across ages and countries better than international sports competitions. Sports news excites people, generating conversations at work and at home throughout the duration of the competition. The popularity of these sporting events engages the general public through print and video channels, but it also offers the opportunity for news beyond the competition results - specifically, how science and scientific principles and properties tie in to the sport. Take the Olympics and the World Cup, for example. News sites were more motivated to write and run stories about the aerodynamics of a soccer ball or science behind Olympic bobsleds because these topics are timely: timeliness is one of the most important reasons news stories get written and published. And analysis of even a small sample of news stories and the language used will show why the news organization posted the story. Since the science content is being translated for the general public, the topics can provide a more general explanation of the science behind sporting events, equipment and the act of doing the sport. But beyond international sporting events, even the opening day of baseball, first night of ice hockey, the start of football and the beginning of basketball season provide opportunities for news organizations to provide science news to the public. Scientists need to get ready to collaborate with journalists to tap into the next big sporting event - Super Bowl XLIX. Although it has not been determined which teams are playing yet, scientists can start preparing content-rich stories on the physics of a football, the climate of Phoenix, Arizona, and the green mission of the University of Phoenix Stadium (the location of Super Bowl 2015). This is an opportunity for scientists and media outlets to add science content knowledge to the hype of the event. After the Super Bowl comes the 2016 Summer Olympics in Rio, which has already been in the news with reporters covering water contamination issues and sustainable construction projects.

Physical activity is one of the key determinants of physical, mental, and social health of children and adolescents. Therefore, the early development of health-relevant behavior patterns is of high relevance. To examine the impact of selected socioeconomic factors as well as media consumption, on sports activities and the motor skills of 10- to 14-year-old secondary school students. Body height and body weight were measured. The motor skills were determined with the Deutschen Motorik Test (DMT 6‑18; German Motor Test). Information about media use, media equipment, recreational sports activities, migration status, and the parents' profession was collected by means of a standardized questionnaire. A total of 391 adolescents have been tested (male 235; female 156). Body mass index (BMI) types are evenly distributed on gender. On a weekday, the pupils spend 10.3 h using media (SD ± 9.1 h). On weekends, media use increases up to 12 h per day on average (SD ± 9.7 h). The number of available media is independent from the age of the respondents and the social status of their families. According to bivariate correlations, heavy media use, a high BMI as well as migration status correlate negatively with both sports activities and motor skills. BMI seems to have the strongest influence on athletic performance (b = 0.41). Media use is an important determinant of juvenile sports activity and motor performance, being part of a complex juvenile leisure behavior.

Catastrophic Head Injuries in High School and Collegiate Sports

PubMed Central

2001-01-01

Objective: To describe the incidence of catastrophic head injuries in a variety of high school and college sports. Design and Setting: Data on catastrophic head injuries were compiled in a national surveillance system maintained by the National Center for Catastrophic Sports Injury Research. The data were compiled with the assistance of coaches, athletic trainers, athletic directors, executive officers of state and national athletic organizations, a national newspaper clipping service, professional associates of the researchers, and national sport organizations. Subjects: Data included all high school and college athletic programs in the United States. Measurements: Background information on the athlete (age, height, weight, experience, previous injury, etc), accident information, immediate and postaccident medical care, type of injury, and equipment involved. Autopsy reports were used when available. Results: A football-related fatality has occurred every year from 1945 through 1999, except for 1990. Head-related deaths accounted for 69% of football fatalities, cervical spinal injuries for 16.3%, and other injuries for 14.7%. High school football produced the greatest number of football head-related deaths. From 1984 through 1999, 69 football head-related injuries resulted in permanent disability. Sixty-three of the injuries were associated with high school football and 6 with college football. Although football has received the most attention, other sports have also been associated with head-related deaths and permanent disability injuries. From 1982 through 1999, 20 deaths and 19 permanent disability injuries occurred in a variety of sports. Track and field, baseball, and cheerleading had the highest incidence of these catastrophic injuries. Three deaths and 3 injuries resulting in permanent disability have occurred in female participants. Conclusions/Recommendations: Reliable data collection systems and continual analysis of the data can help us to reduce the number of catastrophic head-related injuries. I include additional recommendations for injury prevention. PMID:12937502

Prevention of sport injuries is crucial to maximise the health and societal benefits of a physically active lifestyle. To strengthen the translation and implementation of the available evidence base on effective preventive measures, a range of potentially relevant strategies should be considered. Our aim was to identify and categorise intervention strategies for the prevention of acute sport injuries evaluated in the scientific literature, applying the Haddon matrix, and identify potential knowledge gaps. Five electronic databases were searched (PubMed, EMBASE, SPORTDiscus, CINAHL, Cochrane) for studies that evaluated the effect of interventions on the occurrence of acute sport injuries. Studies were required to include a control group/condition, prospective data collection, and a quantitative injury outcome measure. A total of 155 studies were included, mostly randomised controlled trials (43%). The majority of studies (55%) focussed on strategies requiring a behavioural change on the part of athletes. Studies predominantly evaluated the preventive effect of various training programmes targeted at the 'pre-event' phase (n = 73) and the use of equipment to avoid injury in the 'event phase' (n = 29). A limited number of studies evaluated the preventive effect of strategies geared at rules and regulations (n = 14), and contextual modifications (n = 18). Studies specifically aimed at preventing re-injuries were a minority (n = 8), and were mostly related to ankle sprains (n = 5). Valuable insight into the extent of the evidence base of sport injury prevention studies was obtained for 20 potential intervention strategies. This approach can be used to monitor potential gaps in the knowledge base on sport injury prevention.

Health, integrity, and doping in sports for children and young adults. A resolution of the European Academy of Paediatrics.

The European Academy of Paediatrics (EAP) is dedicated to promoting healthy lifestyles for children from birth into young adulthood. Physical exercise and leisure are essential to the development of healthy bodies, strong minds, and social skills. All children, without regard to their physical or mental capacities, should be provided with the time, the leadership, the facilities, and the equipment needed to exercise through sports while enjoying playing, even competing, in an environment appropriate to their capacities and aspirations. During exercise and sports, children should be assured of a safe and an appropriate environment that protects and promotes their human rights. Top sports that engage the best competitive athletes in an age group, in a region, in a country, or in the world should provide role models and even dreams for all children. These top sports, however, are also most usually surrounded by large political, economic, and/or business interests where only the best can compete while at times exacting a too high physical and/or psychological cost for those who have survived the cut, made the grade. Alongside this more and more children are being raised in environments with fewer open spaces as well as inside a media and digital culture making significantly less room for the enjoyment of physical exercise and leisure. Children's diets have also been changed dramatically by a significant intake of calorierich foods, which often have little nutritional value and which even a child's high metabolism rates not able to burn off efficiently. Conclusion With this Resolution, the EAP is calling for a renewed look at the role of sports and leisure in the lives of children and, by implication, at the way we structure, finance, and promote sports in Europe. The EAP is also asking that this Resolution be adopted by all organizers of sports involving children and young adults in Europe (and beyond), be that on the playground, in schools, in clubs, or in professional sporting organizations. The EAP would like that every child, throughout his or her childhood years and into young adulthood, can fully participate in sports in a safe environment where winning is playing and playing is winning.

[Injury patterns and typical stress situations in paragliding].

PubMed

Bohnsack, M; Schröter, E

2005-05-01

Paragliding is known as a high risk sport with a substantial rate of severe and fatal injuries. Analysis of typical injury mechanisms and statistics showed that the total rate of paragliding injuries has decreased in recent years for an increasing number of pilots. In 2003, the rate of severe and fatal injuries in paragliding was less than that of other air sports and motorcycling. Through the introduction of a spine protector system in Germany and Austria, the number of vertebral fractures decreased significantly between 2000 and 2003. Most other injuries, especially of the lower extremities, could be avoided by adequate and farsighted flight behavior. Qualified instruction with regular training, standardized development of safety equipment and consequent analysis of paragliding injuries will help to improve the safety status in paragliding.

Ice hockey is a fast-paced sport played by increasing numbers of children and adolescents in North America and around the world. Requiring a unique blend of skill, finesse, power and teamwork, ice hockey can become a lifelong recreational activity. Despite the rising popularity of the sport, there is ongoing concern about the high frequency of musculoskeletal injury associated with participation in ice hockey. Injury rates in ice hockey are among the highest in all competitive sports. Numerous research studies have been implemented to better understand the risks of injury. As a result, rule changes were adopted by the USA Hockey and Hockey Canada to raise the minimum age at which body checking is permitted to 13–14 years (Bantam level) from 11–12 years (Pee Wee). Continuing the education of coaches, parents and players on rules of safe play, and emphasizing the standards for proper equipment use are other strategies being implemented to make the game safer to play. The objective of this article was to review the evaluation, management and prevention of common lower extremity youth hockey injuries. PMID:27920584

Objective: To provide certified athletic trainers, team physicians, emergency responders, and other health care professionals with recommendations on how to best manage a catastrophic cervical spine injury in the athlete. Background: The relative incidence of catastrophic cervical spine injury in sports is low compared with other injuries. However, cervical spine injuries necessitate delicate and precise management, often involving the combined efforts of a variety of health care providers. The outcome of a catastrophic cervical spine injury depends on the efficiency of this management process and the timeliness of transfer to a controlled environment for diagnosis and treatment. Recommendations: Recommendations are based on current evidence pertaining to prevention strategies to reduce the incidence of cervical spine injuries in sport; emergency planning and preparation to increase management efficiency; maintaining or creating neutral alignment in the cervical spine; accessing and maintaining the airway; stabilizing and transferring the athlete with a suspected cervical spine injury; managing the athlete participating in an equipment-laden sport, such as football, hockey, or lacrosse; and considerations in the emergency department.

[Injury patterns and prophylaxis in inline skating].

PubMed

Jerosch, J; Heck, C

2005-05-01

Inline skating has become one of the fastest growing sports since its appearance in 1980. The increasing number of inline skaters has also led to a rising incidence of injuries. The most common injury is the distal fracture of the radius, which occurs in 50% of all fractures. There are several reasons for increasing serious injuries in inline skating. The majority of skaters do not wear proper protective equipment (helmet, elbow, knee and wrist protectors), however, many users can not handle their inline skates in dangerous situations. All skaters should take care by buying industrially tested inline skates and appropriate protective equipment; novice skaters should additionally attend special skating schools to learn skating, braking and the the correct falling techniques.

Padel is a relatively new sport, with steady participation increases over the past 50 years. However, there is a need for data examining injury and associated risk factors. The study examined how intrinsic (e.g. age and sex) and extrinsic factors (e.g. padel participation and equipment) were associated with injury in recreational padel players. A self-administered questionnaire completed by 80 recreational padel players between September 2014 and March 2015 acquired data on: respondent demographics and padel-related activities; the number of injuries within the past year; characteristics of the last injury sustained; and extrinsic factors including respondents' evaluations of equipment (e.g., racquet control/power, footwear cushioning, flexibility, traction). χ2 tests compared the proportion of respondents reporting injuries in the past year among those reporting and not reporting equipment-related issues. Most respondents were male (57.5%), aged 30-40 years (46.3%), and played more than 2 padel sessions/week (48.8%). Overall, 40.0% reported sustaining at least one injury during the past year. Sex, age, frequency of padel sessions/week, and years of padel experience were not associated with the reporting of injury within the past year (P>0.05). The proportion of padel players reporting injuries in the past year was greater among those that wore padel-specific footwear than those that wore another kind of sports footwear (50.0% vs. 23.3%; P=0.02). Recreational padel players wearing padel-specific footwear were more at risk for injury than those not. Our findings highlight the need for additional research regarding injury risk and footwear.

The incidence of sport-related concussion (SRC) in high school football is well documented. However, limited prospective data are available regarding how player characteristics and protective equipment affect the incidence of SRC. To determine whether the type of protective equipment (helmet and mouth guard) and player characteristics affect the incidence of SRC in high school football players. Cohort study; Level of evidence, 2. Certified athletic trainers (ATs) at each high school recorded the type of helmet worn (brand, model, purchase year, and recondition status) by each player as well as information regarding players' demographics, type of mouth guard used, and history of SRC. The ATs also recorded the incidence and days lost from participation for each SRC. Incidence of SRC was compared for various helmets, type of mouth guard, history of SRC, and player demographics. A total of 2081 players (grades 9-12) enrolled during the 2012 and/or 2013 football seasons (2287 player-seasons) and participated in 134,437 football (practice or competition) exposures. Of these players, 206 (9%) sustained a total of 211 SRCs (1.56/1000 exposures). There was no difference in the incidence of SRC (number of helmets, % SRC [95% CI]) for players wearing Riddell (1171, 9.1% [7.6%-11.0%]), Schutt (680, 8.7% [6.7%-11.1%]), or Xenith (436, 9.2% [6.7%-12.4%]) helmets. Helmet age and recondition status did not affect the incidence of SRC. The rate of SRC (hazard ratio [HR]) was higher in players who wore a custom mouth guard (HR = 1.69 [95% CI, 1.20-2.37], P < .001) than in players who wore a generic mouth guard. The rate of SRC was also higher (HR = 1.96 [95% CI, 1.40-2.73], P < .001) in players who had sustained an SRC within the previous 12 months (15.1% of the 259 players [95% CI, 11.0%-20.1%]) than in players without a previous SRC (8.2% of the 2028 players [95% CI, 7.1%-9.5%]). Incidence of SRC was similar regardless of the helmet brand (manufacturer) worn by high school football players. Players who had sustained an SRC within the previous 12 months were more likely to sustain an SRC than were players without a history of SRC. Sports medicine providers who work with high school football players need to realize that factors other than the type of protective equipment worn affect the risk of SRC in high school players. © 2014 The Author(s).

The purpose of this study was to assess the characteristics and prevalence of sports-related injuries in visually disabled athletes of the Brazilian football 5-a-side team. The participants were 13 male athletes, all classified as B1 visual class, members of the Brazilian team, who played in five consecutive international competitions. Data were collected using the Brazilian Paralympic Committee and the Brazilian Confederation of Sports for the Blind report form. From the total of 13 athletes, 11 succumbed to some form of injury during the 5 competitions, which incorporated 23 matches, representing a prevalence of 84.6%. A total of 35 sports injuries were recorded, giving a clinical incidence of 2.7 injuries per athlete and an injury risk of 0.85 and an incidence rate of 0.12 injuries per match. Traumatic injuries (80%) were more common than overuse injuries (20%) (p<0.05). The highest distribution of injury was in the lower limbs (80%), followed by the head (8.6%), spine (5.7%) and upper limbs (5.7%). The body regions most affected were the knee (28.6%), feet (17.1%), ankle (11.4%) and thigh (11.4%). Contusions (31.4%), sprains (25.7%) and tendinopathy (8.6%) were the most frequent diagnoses. This is the first study to describe the nature and prevalence of sports-related injuries in 5-a-side football in blind athletes. The results are important in guiding strategies to inform the implementation of preventive pathways and provide a strong rationale for the compulsory use of additional protective equipment. © Georg Thieme Verlag KG Stuttgart · New York.

Brachial neuropraxia in Canadian Atlantic University sport football players: what is the incidence of "stingers"?

PubMed

Charbonneau, Rebecca M E; McVeigh, Sonja A; Thompson, Kara

2012-11-01

The objectives of this study were (1) to determine the incidence of brachial neuropraxia (stingers) among varsity football players during the 2010 season; (2) to determine if associations exist between sustaining a stinger and previous history of stingers, years played, equipment, age, body mass index (BMI), and conditioning; and (3) to provide descriptive statistics regarding stingers and position played, symptoms, activity during injury, mechanism of tackling, and reporting of stingers. Retrospective. Canadian Atlantic University Sport football league. Two hundred forty-four players. Two written questionnaires. Number of players experiencing stingers that occurred during the 2010 season. The incidence was 26% (64 of 244). A multivariate analysis revealed that previous history of a stinger (P < 0.0001) and years played (P = 0.0018) were associated with sustaining a stinger. There was no statistically significant effect related to additional equipment, a player's age, BMI, or participation in a strength training program. Linebackers, offensive linemen, and wide receivers had the highest incidence of stingers. The most frequent symptoms reported were tingling, numbness, burning, and weakness. Of all stingers sustained, only 59% (38 of 64) were reported to medical staff. Stingers are a common injury in Canadian university football and are underreported to medical staff. Education of players at increased risk is needed.

Coronal mass ejections (CMEs) represent a great concentration of mass and energy input into the lower corona. They have come to be recognized as the major driver of physical conditions change in the Sun-Earth system. Consequently, observations of CMEs are important for understanding and ultimately predicting space weather conditions. This paper discusses a proposed mission, the Solar Polar Orbit Radio Telescope (SPORT) mission, which will observe the propagation of interplanetary CMEs to distances of near 0.35 AU from the Sun. The orbit of SPORT is an elliptical solar polar orbit. The inclination angle between the orbit and ecliptic plane should be about 90°. The main payload on board SPORT will be an imaging radiometer working at the meter wavelength band (radio telescope), which can follow the propagation of interplanetary CMEs. The images that are obtained by the radio telescope embody the brightness temperature of the objectives. Due to the very large size required for the antenna aperture of the radio telescope, we adopt interferometric imaging technology to reduce it. Interferometric imaging technology is based on indirect spatial frequency domain measurements plus Fourier transformation. The SPORT spacecraft will also be equipped with a set of optical and in situ measurement instruments such as a EUV solar telescope, a solar wind ion instrument, an energetic particle detector, a magnetometer, a wave detector and a solar radio burst spectrometer.

2004-03-01

Injuries sustained by Australian Defence Force (ADF) personnel during non-combat military training and sports activity are associated with increasing costs due to work days lost, medical treatment, compensation, and early retirement. In 2001, the ADF commissioned a systematic review of the evidence-base for reducing injuries associated with physical activity, while at the same time improving physical activity participation rates to sustain a trained, fit and deployable workforce. Literature from on-line library databases, relevant unclassified military reports, and material from previously published sport-specific injury countermeasure reviews were systematically and critically analysed to address the study aims. Modification of intensity, frequency and duration of basic military training activities and improved equipment is likely to reduce injury occurrence. Sports injury countermeasures used for the civilian population have merit for the ADF physical activity program. Injury countermeasures should be designed to minimise any possible deterrent effect on the motivation to participate in regular physical activity. Increasing the participation of ADF personnel in physical activity in the presence of evidence-based injury prevention strategies has the potential to increase health, fitness and deployability with minimal impact on injury frequency. Recommendations arising from the review include injury intervention trials in basic military training and sports. These and other interventions should be supported by refinement to ADF injury surveillance systems. Research should focus on interventions with the greatest gain for fitness, deployability, and cost effectiveness.

Children, older adults, disabled and special needs athletes, and female athletes who participate in outdoor and wilderness sports and activities each face unique risks. For children and adolescents traveling to high altitude, the preparticipation physical evaluation should focus on risk assessment, prevention strategies, early recognition of altitude-related symptoms, management plans, and appropriate follow-up. As the risk and prevalence of chronic disease increases with age, both older patients and providers need to be aware of disease and medication-specific risks relative to wilderness sport and activity participation. Disabled and special needs athletes benefit from careful pre-event planning for the potential medical issues and equipment modifications that may affect their health in wilderness environments. Issues that demand special consideration for female adventurers include pregnancy, contraceptive use, menses, and ferritin levels at altitude. A careful preparticipation evaluation that factors in unique, population- specific risks will help special populations stay healthy and safe on wilderness adventures. The PubMed and SportDiscus databases were searched in 2014 using both MeSH terms and text words and include peer-reviewed English language articles from 1977 to 2014. Additional information was accessed from Web-based sources to produce this narrative review on preparticipation evaluation for special populations undertaking wilderness adventures. Key words include children, adolescent, pediatric, seniors, elderly, disabled, special needs, female, athlete, preparticipiation examination, wilderness medicine, and sports. Copyright © 2015.

The present study aimed at investigating the influence of home, neighbourhood and school environmental factors on adolescents' engagement in self-reported extracurricular physical activity and leisure time sports and on MVPA objectively measured by accelerometers. Environmental factors were assessed using questionnaires. Gender specific hierarchical regression analyses were conducted, with demographic variables entered in the first block, and environmental, psychosocial factors and interactions terms entered in the second block. Participation in extracurricular activities at school was positively related to the number of organized activities and the provision of supervision. Perceived accessibility of neighborhood facilities was not related to engagement in leisure time sports, whereas the availability of sedentary and physical activity equipment was. Findings were generally supportive of ecological theories stating that behaviors are influenced by personal and environmental factors that are constantly interacting. PMID:20041023

Background and Purpose Child safety campaigns play an important role in disseminating injury prevention information to families. A critical discourse analysis of gender bias in child safety campaign marketing materials can offer important insights into how families are represented and the potential influence that gender bias may have on uptake of injury prevention information. Methods Our approach was informed by poststructural feminist theory, and we used critical discourse analysis to identify discourses within the poster materials. We examined the national Safe Kids Canada Safe Kids Week campaign poster material spanning twenty years (1997-2016). Specifically, we analyzed the posters' typeface, colour, images, and language to identify gender bias in relation to discourses surrounding parenting, safety, and societal perceptions of gender. Results The findings show that there is gender bias present in the Safe Kids Week poster material. The posters represent gender as binary, mothers as primary caregivers, and showcase stereotypically masculine sporting equipment among boys and stereotypically feminine equipment among girls. Interestingly, we found that the colour and typeface of the text both challenge and perpetuate the feminization of safety. Discussion It is recommended that future child safety campaigns represent changing family dynamics, include representations of children with non-traditionally gendered sporting equipment, and avoid the representation of gender as binary. This analysis contributes to the discussion of the feminization of safety in injury prevention research and challenges the ways in which gender is represented in child safety campaigns. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

Promoting the participation of children with disabilities in sports, recreation, and physical activities.

PubMed

Murphy, Nancy A; Carbone, Paul S

2008-05-01

The benefits of physical activity are universal for all children, including those with disabilities. The participation of children with disabilities in sports and recreational activities promotes inclusion, minimizes deconditioning, optimizes physical functioning, and enhances overall well-being. Despite these benefits, children with disabilities are more restricted in their participation, have lower levels of fitness, and have higher levels of obesity than their peers without disabilities. Pediatricians and parents may overestimate the risks or overlook the benefits of physical activity in children with disabilities. Well-informed decisions regarding each child's participation must consider overall health status, individual activity preferences, safety precautions, and availability of appropriate programs and equipment. Health supervision visits afford pediatricians, children with disabilities, and parents opportunities to collaboratively generate goal-directed activity "prescriptions." Child, family, financial, and societal barriers to participation need to be directly identified and addressed in the context of local, state, and federal laws. The goal is inclusion for all children with disabilities in appropriate activities. This clinical report discusses the importance of physical activity, recreation, and sports participation for children with disabilities and offers practical suggestions to pediatric health care professionals for the promotion of participation.

Ubiquitous (pervasive) computing is a term for a synergetic use of sensing, communication and computing. Pervasive use of computing has seen a rapid increase in the current decade. This development has propagated in applied sport science and everyday life. The work presents a survey of recent developments in sport and leisure with emphasis on technology and computational techniques. A detailed analysis on new technological developments is performed. Sensors for position and motion detection, and such for equipment and physiological monitoring are discussed. Aspects of novel trends in communication technologies and data processing are outlined. Computational advancements have started a new trend - development of smart and intelligent systems for a wide range of applications - from model-based posture recognition to context awareness algorithms for nutrition monitoring. Examples particular to coaching and training are discussed. Selected tools for monitoring rules' compliance and automatic decision-making are outlined. Finally, applications in leisure and entertainment are presented, from systems supporting physical activity to systems providing motivation. It is concluded that the emphasis in future will shift from technologies to intelligent systems that allow for enhanced social interaction as efforts need to be made to improve user-friendliness and standardisation of measurement and transmission protocols.

An investigation of the effects of sports-related concussion in youth using functional magnetic resonance imaging and the head impact telemetry system.

One of the most commonly reported injuries in children who participate in sports is concussion or mild traumatic brain injury (mTBI). Children and youth involved in organized sports such as competitive hockey are nearly six times more likely to suffer a severe concussion compared to children involved in other leisure physical activities. While the most common cognitive sequelae of mTBI appear similar for children and adults, the recovery profile and breadth of consequences in children remains largely unknown, as does the influence of pre-injury characteristics (e.g. gender) and injury details (e.g. magnitude and direction of impact) on long-term outcomes. Competitive sports, such as hockey, allow the rare opportunity to utilize a pre-post design to obtain pre-injury data before concussion occurs on youth characteristics and functioning and to relate this to outcome following injury. Our primary goals are to refine pediatric concussion diagnosis and management based on research evidence that is specific to children and youth. To do this we use new, multi-modal and integrative approaches that will: 1. Evaluate the immediate effects of head trauma in youth. 2. Monitor the resolution of post-concussion symptoms (PCS) and cognitive performance during recovery. 3. Utilize new methods to verify brain injury and recovery. To achieve our goals, we have implemented the Head Impact Telemetry (HIT) System. (Simbex; Lebanon, NH, USA). This system equips commercially available Easton S9 hockey helmets (Easton-Bell Sports; Van Nuys, CA, USA) with single-axis accelerometers designed to measure real-time head accelerations during contact sport participation. By using telemetric technology, the magnitude of acceleration and location of all head impacts during sport participation can be objectively detected and recorded. We also use functional magnetic resonance imaging (fMRI) to localize and assess changes in neural activity specifically in the medial temporal and frontal lobes during the performance of cognitive tasks, since those are the cerebral regions most sensitive to concussive head injury. Finally, we are acquiring structural imaging data sensitive to damage in brain white matter.

Paragliding injuries.

1991-06-01

Regulations controlling the sport of paragliding were issued in April 1987 by the German Department of Transportation. The growing popularity of this sport has led to a steady increase in the number of associated injuries. This study presents the incidence, localization and degree of injuries associated with paragliding documented in Germany, Austria and Switzerland. The 283 injuries suffered by 218 paragliders were documented in the period 1987-1989: 181 occurred during landing, 28 during starting procedures and nine during flight. The mean patient age was 29.6 years. There were 34.9% spinal injuries, 13.4% upper extremity injuries and 41.3% lower limb injuries. Over half of these injuries were treated surgically and in 54 instances permanent disability remained. In paragliding the lower extremities are at greatest risk of injury during landing. Proper equipment, especially sturdy footwear, exact training in landing techniques as well as improved instruction in procedures during aborted or crash landings is required to reduce the frequency of these injuries.

Currently, the tendency of the car manufacturers is to continue the expansion of the global production of SUVs (Sport Utility Vehicle), while observing the requirements imposed by the new pollution standards by developing new technologies like DHEP (Diesel Hybrid Electric Powertrain). Experience has shown that the transient regimes are the most difficult to control from an economic and ecological perspective. As a result, this paper will highlight the behaviour of such engines that are provided in a middle class SUV (Sport Utility Vehicle), which operates in such states. We selected the transient regimes characteristic to the NMVEG (New Motor Vehicle Emissions Group) cycle. The investigations using the modelling platform AMESim allowed for rigorous interpretations for the 16 acceleration and 18 deceleration states. The results obtained from the simulation will be validated by experiments.

This paper describes the performance of an outage free SXH (Synchronous Digital Hierarchy) interface 256 QAM modem. An outage free DMR (Digital Microwave Radio) is achieved by a high coding gain trellis coded SPORT QAM and Super Multicarrier modem. A new frame format and its associated circuits connect the outage free modem to the SDH interface. The newly designed VLSI's are key devices for developing the modem. As an overall modem performance, BER (bit error rate) characteristics and equipment signatures are presented. A coding gain of 4.7 dB (at a BER of 10(exp -4)) is obtained using SPORT 256 QAM and Viterbi decoding. This coding gain is realized by trellis coding as well as by increasing of transmission rate. Roll-off factor is decreased to maintain the same frequency occupation and modulation level as ordinary SDH 256 QAM modern.

Hill and Barton (2005) showed that fighters in tae kwon do, boxing, and wrestling who wore red jerseys during the 2004 Olympic Games won more often than those wearing blue jerseys. Regarding these results, this study investigated the effects of jersey color during a combat situation on fighters' physical parameters of strength and heart rate. An artificial, experimental combat situation was created in which the color of sport attire was assigned randomly. Fourteen pairs of male athletes matched for weight, height, and age had to fight each other: once in a red jersey and once in a blue. Heart rate (before, during, and after the fight) and strength (before the fight) were tested wearing the blue and the red jerseys. Participants wearing red jerseys had significantly higher heart rates and significantly higher pre-contest values on the strength test. Results showed that participants' body functions are influenced by wearing red equipment.

Athletes Doing Arabesques: Important Considerations in the Care of Young Dancers.

Dance is as much a sport as an art form. Sports medicine clinicians seeing dancers in their practice will need to be familiar with the unique characteristics of dance in order to provide proper care. Dance encompasses different forms, which vary in equipment and terminology. The epidemiology of dance injuries has historically focused on ballet, but there is increasing research on other dance forms. Lower extremity and back injuries predominate. Injury prevention, both primary and secondary, is at the heart of dance medicine. Primary prevention includes preseason conditioning, identifying risk factors for injury, and recognizing the female athlete triad. Secondary prevention includes a comprehensive approach to injury rehabilitation, an appreciation for the unique demands of dance, and an understanding of the particulars of the injury being treated. Dancers may have difficulty accessing medical care or following prescribed advice; the proactive clinician will anticipate these situations.

To describe injury rates and patterns in the emerging sport of hardcourt bike polo (HBP). Descriptive survey. HBP playing areas (urban flat concrete surfaces). Twenty-two adult (≥18 years) HBP players who presented to a routine thrice-weekly playing site completed the survey. Participants completed a survey that was used to evaluate demographics; frequency of play; rate, localization, and severity of injuries sustained in the past 1 year; and use of medical care. The incidence of sustaining an injury in 1 year was 0.86. The main sites of injury involved the knee, elbow, wrist, and hand. Medical attention was sought by 15% of the injured players. HBP is a rapidly evolving urban sport in which participants are at risk for trauma-related injury, some of which may be preventable by the addition of appropriate safety equipment.

Boxing: medical care in and out of the ring.

PubMed

Gambrell, Robert C

2007-10-01

Boxing may well be the oldest sport known to mankind and probably the most controversial. Injuries are common in boxing, occurring most often to the head, neck, face, and hands. Brain injury, both acute and chronic, is the major risk for potential catastrophe. Medical care for the boxer extends beyond the competition in the boxing ring; the ringside physician is responsible for protecting both boxers and must make quick decisions about their continued participation based upon a limited examination. A thorough knowledge of the rules and regulations of boxing is necessary for the ringside physician to effectively care for the athlete. In spite of the perceived brutality associated with the sport, most injuries are minor, although serious injuries and deaths do occur, most commonly due to brain injury. Given the potential for catastrophic injury, the ringside physician must be prepared and equipped to care for the boxer.

A review of the effects of martial arts practice on health.

PubMed

Woodward, Thomas W

2009-02-01

Martial arts are ancient forms of combat, modified for modern sport and exercise. Participation in the martial arts is increasing, particularly for youth. Martial arts provide health-promoting and meaningful exercise for millions of practitioners. Benefits from this practice include better overall health and balance, as well as an improved sense of psychological well being. They do not promote aggression and may be used as a treatment modality for youth who are at-risk for violence. This article provides an overview of martial arts for physicians who may evaluate such injuries in their practice. Physicians may wish to consider recommending martial arts to patients as a beneficial form of exercise. They are relatively safe compared to many other sports, and most martial arts injuries are comparatively minor. Risks can possibly be reduced by limiting exposure of inexperienced students, as well as using protective equipment, including mouthguards, eye/face protection, headgear, and padding.

The objective was to determine to what extent daily physical education can be implemented in primary schools, what barriers exist and how to overcome the mentioned barriers. Moreover, it was analysed to what extent daily physical education is accepted by teachers, external trainers, parents and students. Semi-structured interviews with parents (n=7), teachers (n=5) and external trainers (n=6) of the intervention schools. The intervention students (n=44) were surveyed within focus groups. All surveyed groups appraised the implementation of daily school sports as successful. The cooperation between the schools and the sports club should be maintained during a comprehensive implementation of daily physical education. Besides an improved lessons quality teachers and external trainers reported an improved social behaviour of the children. Parents perceived positive effects on the child development. All groups believe that daily physical education increases the enjoyment of children in sports. As a certain barrier a lack of resources (e. g., facilities, equipment, financial resources) in the schools were mentioned. The cooperation between the schools and the sports club proved to be an applicable model to implement daily physical education. The combination of teachers and external trainers can contribute to a higher lesson quality. Considering the perceived potentials of daily physical education by all surveyed groups, a comprehensive implementation of systematic daily physical activity promotion in the primary school setting should be tapped more strongly in future. © Georg Thieme Verlag KG Stuttgart · New York.

To estimate the incidence of patients presenting to emergency departments (EDs) for facial trauma sustained from participation in combat sports and evaluate injury patterns and patient demographics. The National Electronic Injury Surveillance System (NEISS) was evaluated for facial injuries from wrestling, boxing, and martial arts leading to ED visits from 2008 to 2013. Relevant entries were examined for injury mechanism, location, type, as well as other patient characteristics. There were 1143 entries extrapolating to an estimated 42 395 ED visits from 2008 to 2013. Injury rates for boxing, marital arts, and wrestling were, respectively, 44, 56, and 120 injuries per 100 000 participants. Males comprised the majority (93.7%). A plurality of injuries involved lacerations (46.0%), followed by fractures (26.2%) and contusions/abrasions (19.3%). The proportion of fractures was highest among boxers (36.9%). Overall, the most common mechanisms of injury were punching, kicking, and head butting. The significant number of ED visits resulted from combat sports facial trauma, reinforcing the importance of familiarity with injury patterns among practitioners managing facial trauma. As most injuries involve individuals younger than 19 despite guidelines suggesting children and adolescents avoid combat sports, these findings may be used for patient education and encouragement of the use of personal protective equipment. Furthermore, injury patterns reported in this analysis may serve as an adjunct for enhancing clinical history taking and physical examination. © The Author(s) 2016.

Selected Cutaneous Disorders in Athletes

The author discusses selected cutaneous diseases seen in the athlete. These diseases may be caused by interaction with the elements, the playing surface, other athletes, or the clothing or equipment worn during sport. All of these dermatological conditions are relatively common, but the physically active individual can suffer from these maladies and their complications more often than the inactive person. The emphasis in caring for the participant is on prevention, early recognition and practical aspects of management of cutaneous diseases. PMID:21264034

To determine if there is evidence that equipment use reduces sport concussion risk and/or severity. 12 electronic databases were searched using a combination of Medical Subject Headings and text words to identify relevant articles. Specific inclusion and exclusion criteria were used to select studies for review. Data extracted included design, study population, exposure/outcome measures and results. The quality of evidence was assessed based on epidemiologic criteria regarding internal and external validity (ie, strength of design, sample size/power calculation, selection bias, misclassification bias, control of potential confounding and effect modification). In total, 51 studies were selected for review. A comparison between studies was difficult due to the variability in research designs, definition of concussion, mouthguard/helmet/headgear/face shield types, measurements used to assess exposure and outcomes, and variety of sports assessed. The majority of studies were observational, with 23 analytical epidemiologic designs related to the subject area. Selection bias was a concern in the reviewed studies, as was the lack of measurement and control for potentially confounding variables. There is evidence that helmet use reduces head injury risk in skiing, snowboarding and bicycling, but the effect on concussion risk is inconclusive. No strong evidence exists for the use of mouthguards or face shields to reduce concussion risk. Evidence is provided to suggest that full facial protection in ice hockey may reduce concussion severity, as measured by time loss from competition.

Background The incidence of sport-related concussion (SRC) in high school football is well documented. However, limited prospective data are available regarding how player characteristics and protective equipment affect the incidence of SRC. Purpose To determine whether the type of protective equipment (helmet and mouth guard) and player characteristics affect the incidence of SRC in high school football players. Design Cohort study; Level of evidence, 2. Methods Certified athletic trainers (ATs) at each high school recorded the type of helmet worn (brand, model, purchase year, and recondition status) by each player as well as information regarding players’ demographics, type of mouth guard used, and history of SRC. The ATs also recorded the incidence and days lost from participation for each SRC. Incidence of SRC was compared for various helmets, type of mouth guard, history of SRC, and player demographics. Results A total of 2081 players (grades 9–12) enrolled during the 2012 and/or 2013 football seasons (2287 player-seasons) and participated in 134,437 football (practice or competition) exposures. Of these players, 206 (9%) sustained a total of 211 SRCs (1.56/1000 exposures). There was no difference in the incidence of SRC (number of helmets, % SRC [95% CI]) for players wearing Riddell (1171, 9.1% [7.6%–11.0%]), Schutt (680, 8.7% [6.7%–11.1%]), or Xenith (436, 9.2% [6.7%–12.4%]) helmets. Helmet age and recondition status did not affect the incidence of SRC. The rate of SRC (hazard ratio [HR]) was higher in players who wore a custom mouth guard (HR = 1.69 [95% CI, 1.20–2.37], P <.001) than in players who wore a generic mouth guard. The rate of SRC was also higher (HR = 1.96 [95% CI, 1.40–2.73], P <.001) in players who had sustained an SRC within the previous 12 months (15.1% of the 259 players [95% CI, 11.0%–20.1%]) than in players without a previous SRC (8.2% of the 2028 players [95% CI, 7.1%–9.5%]). Conclusion Incidence of SRC was similar regardless of the helmet brand (manufacturer) worn by high school football players. Players who had sustained an SRC within the previous 12 months were more likely to sustain an SRC than were players without a history of SRC. Sports medicine providers who work with high school football players need to realize that factors other than the type of protective equipment worn affect the risk of SRC in high school players.

The origins of karate and its evolution as a sport are described. Karate injuries tend to occur in three main areas: the head and neck, the viscera, and the limbs. Effective legislation controlling karate, which could help prevent injuries, is lacking at the moment and should be established. Recommendations for the prevention of injury include the introduction of weight classes, mandatory provision of protective equipment such as padded flooring, and the outlawing of certain uncontrollable methods of attack.

Collins, Tracy J R

2010-01-01

Between 1885-1900 "Punch" satirized the personality of the New Woman. However, virtually single-handedly it also gave a body and emancipated culture to this otherwise socially abstract personality. Using illustrations from "Punch," this essay argues that using sport specific clothing and equipment in its cartoons, "Punch" completely unintentionally created a liberating picture of women while simultaneously using its captions and border texts to make the New Woman's body signify the anxieties patriarchal culture had about her social personality and politics.

Assessment of the functional capacity of the cardiovascular system is essential in sports medicine. For athletes, the maximal oxygen uptake [Formula: see text] provides valuable information about their aerobic power. In the clinical setting, the (VO(2max)) provides important diagnostic and prognostic information in several clinical populations, such as patients with coronary artery disease or heart failure. Likewise, VO(2max) assessment can be very important to evaluate fitness in asymptomatic adults. Although direct determination of [VO(2max) is the most accurate method, it requires a maximal level of exertion, which brings a higher risk of adverse events in individuals with an intermediate to high risk of cardiovascular problems. Estimation of VO(2max) during submaximal exercise testing can offer a precious alternative. Over the past decades, many protocols have been developed for this purpose. The present review gives an overview of these submaximal protocols and aims to facilitate appropriate test selection in sports, clinical, and home settings. Several factors must be considered when selecting a protocol: (i) The population being tested and its specific needs in terms of safety, supervision, and accuracy and repeatability of the VO(2max) estimation. (ii) The parameters upon which the prediction is based (e.g. heart rate, power output, rating of perceived exertion [RPE]), as well as the need for additional clinically relevant parameters (e.g. blood pressure, ECG). (iii) The appropriate test modality that should meet the above-mentioned requirements should also be in line with the functional mobility of the target population, and depends on the available equipment. In the sports setting, high repeatability is crucial to track training-induced seasonal changes. In the clinical setting, special attention must be paid to the test modality, because multiple physiological parameters often need to be measured during test execution. When estimating VO(2max), one has to be aware of the effects of medication on heart rate-based submaximal protocols. In the home setting, the submaximal protocols need to be accessible to users with a broad range of characteristics in terms of age, equipment, time available, and an absence of supervision. In this setting, the smart use of sensors such as accelerometers and heart rate monitors will result in protocol-free VO(2max) assessments. In conclusion, the need for a low-risk, low-cost, low-supervision, and objective evaluation of VO(2max) has brought about the development and the validation of a large number of submaximal exercise tests. It is of paramount importance to use these tests in the right context (sports, clinical, home), to consider the population in which they were developed, and to be aware of their limitations.

To investigate the alcohol, gambling, and unhealthy food marketing strategies during a nationally televised, free to air, sporting series in Australia. Using the Australian National Rugby League 2012 State of Origin three-game series, we conducted a mixed methods content analysis of the frequency, duration, placement and content of advertising strategies, comparing these strategies both within and across the three games. There were a total of 4445 episodes (mean = 1481.67, SD = 336.58), and 233.23 minutes (mean = 77.74, SD = 7.31) of marketing for alcoholic beverages, gambling products and unhealthy foods and non-alcoholic beverages during the 360 minutes of televised coverage of the three State of Origin 2012 games. This included an average per game of 1354 episodes (SD = 368.79) and 66.29 minutes (SD = 7.62) of alcohol marketing; 110.67 episodes (SD = 43.89), and 8.72 minutes (SD = 1.29) of gambling marketing; and 17 episodes (SD = 7.55), and 2.74 minutes (SD = 0.78) of unhealthy food and beverage marketing. Content analysis revealed that there was a considerable embedding of product marketing within the match play, including within match commentary, sporting equipment, and special replays. Sport is increasingly used as a vehicle for the promotion of range of 'risky consumption' products. This study raises important ethical and health policy questions about the extent and impact of saturation and incidental marketing strategies on health and wellbeing, the transparency of embedded marketing strategies, and how these strategies may influence product consumption.

Sports cycling is becoming increasingly popular over last years. Obtaining and maintaining a proper position on the bike has been shown to be crucial for performance, comfort and injury avoidance. Various techniques of bike fitting are available - from rough settings based on body dimensions to professional services making use of sophisticated equipment and expert knowledge. Modern fitting techniques use mainly joint angles as a criterion of proper position. In this work we examine performance of two proposed methods for dynamic cyclist position assessment based on video data recorded during stationary cycling. Proposed methods are intended for home use, to help amateur cyclist improve their position on the bike, and therefore no professional equipment is used. As a result of data processing, ranges of angles in selected joints are provided. Finally strengths and weaknesses of both proposed methods are discussed.

To determine whether during-exercise rehydration improves swimming performance and whether sports drink or water have differential effects on performance. Randomised controlled multiple crossover trial. A UK competitive swimming club. 19 club-level competitive swimmers, median age (range) 13 (11-17) years. Subjects were scheduled to drink ad libitum commercial isotonic sports drink (3.9 g sugars and 0.13 g salt per 100 mL) or water (three sessions each) or no drink (six sessions) in the course of twelve 75 min training sessions, each of which was followed by a 30 min test set of ten 100 m maximum-effort freestyle sprints each starting at 3 min intervals. Times for the middle 50 m of each sprint measured using electronic timing equipment in a Federation Internationale de Natation (FINA)-compliant six-lane 25 m competition swimming pool. Software-generated individual random session order in sealed envelopes. Analysis subset of eight sessions randomly selected by software after data collection completed. Participants blind to drink allocation until session start. In the analysis data set of 1118 swims, there was no significant difference between swim times for drinking and not drinking nor between drinking water or a sports drink. Mean (SEM) 50 m time for no-drink swims was 38.077 (0.128) s and 38.105 (0.131) s for drink swims, p=0.701. Mean 50 m times were 38.031 (0.184) s for drinking sports drink and 38.182 (0.186) s for drinking water, p=0.073. Times after not drinking were 0.027 s faster than after drinking (95% CI 0.186 s faster to 0.113 s slower). Times after drinking sports drink were 0.151 s faster than after water (95% CI 0.309 s faster to 0.002 s slower). Mean (SEM) dehydration from exercise was 0.42 (0.11)%. Drinking water or sports drink over 105 min of sustained effort swimming training does not improve swimming performance. ISRCTN: 49860006.

To meet growing energy demands, energy efficiency, renewable energy, and on-site generation coupled with effective utilization of exhaust heat will all be required. Additional benefit can be achieved by integrating these distributed technologies into distributed energy resource (DER) systems (or microgrids). This research investigates a method of choosing economically optimal DER, expanding on prior studies at the Berkeley Lab using the DER design optimization program, the Distributed Energy Resources Customer Adoption Model (DER-CAM). DER-CAM finds the optimal combination of installed equipment from available DER technologies, given prevailing utility tariffs, site electrical and thermal loads, and a menu of available equipment.more » It provides a global optimization, albeit idealized, that shows how the site energy loads can be served at minimum cost by selection and operation of on-site generation, heat recovery, and cooling. Five prototype Japanese commercial buildings are examined and DER-CAM applied to select the economically optimal DER system for each. The five building types are office, hospital, hotel, retail, and sports facility. Based on the optimization results, energy and emission reductions are evaluated. Furthermore, a Japan-U.S. comparison study of policy, technology, and utility tariffs relevant to DER installation is presented. Significant decreases in fuel consumption, carbon emissions, and energy costs were seen in the DER-CAM results. Savings were most noticeable in the sports facility (a very favourable CHP site), followed by the hospital, hotel, and office building.« less

Regulations controlling the sport of paragliding were issued in April 1987 by the German Department of Transportation. The growing popularity of this sport has led to a steady increase in the number of associated injuries. This study presents the incidence, localization and degree of injuries associated with paragliding documented in Germany, Austria and Switzerland. The 283 injuries suffered by 218 paragliders were documented in the period 1987-1989: 181 occurred during landing, 28 during starting procedures and nine during flight. The mean patient age was 29.6 years. There were 34.9% spinal injuries, 13.4% upper extremity injuries and 41.3% lower limb injuries. Over half of these injuries were treated surgically and in 54 instances permanent disability remained. In paragliding the lower extremities are at greatest risk of injury during landing. Proper equipment, especially sturdy footwear, exact training in landing techniques as well as improved instruction in procedures during aborted or crash landings is required to reduce the frequency of these injuries.

2004-03-01

Impact mechanics is concerned with the reaction forces that develop during a collision and the dynamic response of structures to these reaction forces. The subject has a wide range of engineering applications, from designing sports equipment to improving the crashworthiness of automobiles. This book develops several different methodologies for analysing collisions between structures. These range from rigid body theory for structures that are stiff and compact, to vibration and wave analyses for flexible structures. The emphasis is on low-speed impact where damage is local to the small region of contact between the colliding bodies. The analytical methods presented give results that are more robust or less sensitive to initial conditions than have been achieved hitherto. As a text, Impact Mechanics builds upon foundation courses in dynamics and strength of materials. It includes numerous industrially relevant examples and end-of-chapter homework problems drawn from industry and sports. Practising engineers will also find the methods presented in this book useful in calculating the response of a mechanical system to impact.

The behaviour of a motorcycle on the road is largely governed by tyre properties. This paper presents experimental and numerical analyses dealing with the influence of tyre properties on the stability of weave and wobble in straight running. The final goal is to find optimal sets of tyre properties that improve the stability of a motorcycle. The investigation is based on road tests carried out on a sport-touring motorcycle equipped with sensors. Three sets of tyres are tested at different speeds in the presence of weave and wobble. The analysis of telemetry data highlights significant differences in the trends of frequency and damping of weave and wobble against speed. The experimental analysis is integrated by a parametric numerical analysis. Tyre properties are varied according to the design of experiments method, in order to highlight the single effects on stability of lateral and cornering coefficient of front and rear tyres.

Ice sledge (or sled) hockey is a fast-paced sport that enables individuals with physical disabilities to play ice hockey. As the attraction to the sport continues to rise, the need for developing better equipment and installing preventative measures for injury will become increasingly important. One such injury includes skin pressure ulceration. A total of 26 subjects including active controls and those with spinal cord injury, multiple sclerosis, limb amputation and traumatic brain injury were studied using a pressure mapping device at the 2012 National Disabled Veterans Winter Sports Clinic to determine the risk for skin pressure ulceration and the impact of cushioning and knee angle positioning on seated pressure distributions. Sledge hockey athletes may be at increased risk for skin pressure ulceration based on seated pressure distribution data. This experiment failed to demonstrate a benefit for specialty cushioning in either group. Interestingly, knee angle positioning, particularly, knee extension significantly lowered the average seated pressures. When considering the risk for skin pressure ulceration, knee angle positioning is of particular clinical importance. More research is warranted, specifically targeting novel cushion and sledge designs and larger groups of individuals with sensory loss and severe spinal deformities. Implications for Rehabilitation Ice sledge (or sled) hockey is a fast-paced and growing adaptive sport played at the Paralympic level. Rehabilitation professionals should consider the potential for skin ulceration in this population of athletes. The effects of cushioning used in the sledge design warrants further investigation. Knee angle positioning; particularly, knee extension significantly lowers seated pressures and may reduce the potential for skin ulceration.

This study aimed at determining the role of proximity to specific types of green spaces (GSes) as well as their spatial location in the relationship with the most morbid cardiovascular diseases (CVD) and diabetes. We measured the accessibility to various types of GS and used a cross-sectional approach at census Dissemination Area (DA) levels in the Montreal and Quebec City metropolitan zones for the period 2006–2011. Poisson and negative binomial regression models were fitted to quantify the relationship between distances to specific types of GS and CVD morbidity as well as some risk factors (diabetes and hypertension) while controlling for several social and environmental confounders. GSes that have sports facilities showed a significant relationship to cerebrovascular diseases: the most distant population had an 11% higher prevalence rate ratio (PRR) compared to the nearest, as well as higher diabetes risk (PRR 9%) than the nearest. However, the overall model performance and the understanding of the role of GSes with sport facilities may be substantially achieved with lifestyle factors. Significantly higher prevalence of diabetes and cerebrovascular diseases as well as lower access to GSes equipped with sports facilities were found in suburban areas. GSes can advantageously be used to prevent some CVDs and their risk factors, but there may be a need to reconsider their types and location. PMID:27089356

Gridiron football injuries.

Stuart, Michael J

2005-01-01

To review the available football epidemiology literature to identify risk factors, facilitate injury prevention and uncover deficiencies that may be addressed by future research. A literature search of Sports Discus (1940-2003), Eric (1967-2003), EMBASE (1988-2003), MEDLINE (1966-2003), CINAHL (1984-2003), and Web of Science (1993-2003) identified the published articles on American football in athletes of high school age and younger. Injury rate increases with the level of play (grade in school), player age, and player experience. The lower extremity (knee and ankle joints) is most frequently injured. Football injuries are much more common in games than in practice, and occur to players who are being tackled, tackling or blocking. Most injuries are mild, including contusion, strain and sprain. Rule changes with the prohibition of initial contact with the helmet or face-mask reduced catastrophic head and neck injuries. Although no sport or recreational activity is completely risk-free, football epidemiology research is critical to injury prevention. The existing medical literature provides some valuable insights, but an increased emphasis on prospective research is required to test the efficacy of preventative measures. Quality research may contribute to a reduction in football injury risk by defining the role of player conditioning and strength training, coaching of safety fundamentals, avoidance of dangerous activities, as well as proper medical supervision and care. Sports medicine personnel, coaches, and officials must strive to minimize injuries through progressive education, improved coaching techniques, effective officiating, and equipment modifications.

In August 2006, the new AZ Alkmaar soccer stadium (capacity 17,000) opened. To provide adequate emergency support, medical teams of Red Cross volunteers and coronary care unit and emergency room nurses were formed, and facilities including automated external defibrillators were made available at the stadium. During every match, 3 teams are placed among the spectators. All patients who had cardiac events were stabilized by the teams and transported to the hospital. They formed the study group. From August 2006 to May 2007, >800,000 individuals attended soccer matches at the new stadium. Four cardiac events (3 out-of-hospital-resuscitations for ventricular fibrillation, 1 patient with chest pain) requiring emergency medical support occurred. On-site resuscitations using defibrillators were successful. Two patients with triple-vessel disease subsequently underwent coronary bypass surgery and implantable cardioverter-defibrillator implantation. One patient had single-vessel disease of the circumflex branch, for which he received a coronary stent. All had uneventful recoveries. An acute coronary syndrome was ruled out in the patient presenting with chest pain. In conclusion, the presence of emergency medical teams at a large sport stadium was of vital importance in the immediate care of critically ill patients. On-site resuscitation using automated external defibrillators was lifesaving in all cases. The presence of medical teams equipped with defibrillators and emergency action plans is recommended at large venues that host sports and other activities.

Energy conservation and solar energy measures are described for two old buildings, different in scale and character, that are being recycled by the Neighborhood Committee for the Asphalt Green into a community Sports and Arts Center and an Environmental Studies Center. The approach taken by the Authority in developing the integrated energy system design for the larger, commercial-scale Sports and Arts Center was to incorporate energy conservation and renewable energy measures that minimize life cycle costs. The benefits of this approach are significant. As documented in this report, energy costs will be reduced from about $50,000 per year (in 1979more » dollars) to $15,000 per year. The final design incorporates exterior shell insulation, on-site mechanical equipment, and a wind energy conversion system to generate electricity for the large lighting and cooling requirements, heat recovery from the ventilation exhaust air, generator motors and refrigeration system, and hot and cold thermal storage for load management. The Environmental Studies Center, formerly a fireboat station on the East River, is a smaller residential-scale structure. The approach in developing the renovation plan was to assess retrofit potential for cost-effective energy conservation, solar domestic hot water, and active and passive solar space heating. Energy measures were selected which would maximize educational potential for school children and which could be replicated by the general public.« less

Several research programs are tackling the use of Wireless Sensor Networks (WSN) at specific fields, such as e-Health, e-Inclusion or e-Sport. This is the case of the project "Ambient Intelligence Systems Support for Athletes with Specific Profiles", which intends to assist athletes in their training. In this paper, the main developments and outcomes from this project are described. The architecture of the system comprises a WSN deployed in the training area which provides communication with athletes' mobile equipments, performs location tasks, and harvests environmental data (wind speed, temperature, etc.). Athletes are equipped with a monitoring unit which obtains data from their training (pulse, speed, etc.). Besides, a decision engine combines these real-time data together with static information about the training field, and from the athlete, to direct athletes' training to fulfill some specific goal. A prototype is presented in this work for a cross country running scenario, where the objective is to maintain the heart rate (HR) of the runner in a target range. For each track, the environmental conditions (temperature of the next track), the current athlete condition (HR), and the intrinsic difficulty of the track (slopes) influence the performance of the athlete. The decision engine, implemented by means of (m, s)-splines interpolation, estimates the future HR and selects the best track in each fork of the circuit. This method achieves a success ratio in the order of 80%. Indeed, results demonstrate that if environmental information is not take into account to derive training orders, the success ratio is reduced notably.

Despite a focus on the incidence and effects of concussion, nondisclosure of sports-related concussions among retired players from the National Football League (NFL) has yet to be examined. Examine the prevalence of and factors associated with nondisclosure of sports-related concussions in former NFL athletes. Cross-sectional study; Level of evidence, 3. A sample of 829 former NFL players completed a general health survey. This historical cohort included players who had played before World War II to 2001. Respondents retrospectively recalled sports-related concussions that they sustained during their professional careers and whether at least one of these sports-related concussions was not reported to medical staff. We computed the prevalence of nondisclosure among those recalling sport-related concussions during their professional careers. Multivariable binomial regression estimated adjusted prevalence ratios (PR) with 95% confidence intervals (CIs) controlling for race/ethnicity, number of years played, primary position played, professional career concussion history, and playing era. Playing era was categorized by whether the majority of a player's career was before or after a 1976 rule change to limit contact ("spearing"). Overall, 417 (50.3%) respondents reported they had sustained a concussion and did not inform medical staff at least once during their professional playing career. Nonwhite respondents had a higher prevalence of nondisclosure than white/non-Hispanic respondents (adjusted PR = 1.19; 95% CI, 1.02-1.38). An interaction between professional career concussion history and playing era was also found ( P = .08). Compared with those in the pre-spearing rule change group with 1 or 2 concussions, all other groups had larger prevalences of nondisclosure (increases ranging from 41% to 153% in multivariable models). Across concussion strata, nondisclosure prevalence was generally higher in the post-spearing rule change group than the pre-spearing rule change group, with the largest differences found among those with 1 or 2 concussions or those with 3 or 4 concussions. A large proportion of former NFL players in this historical cohort reported at least one instance of not disclosing sports-related concussions to medical staff. Future research on concussion nondisclosure needs to identify mechanisms to improve football players' intentions to disclose concussion-related symptoms to health care providers and to equip health care providers with more effective strategies for timely identification of concussion.

To analyse the characteristics of fatal incidents in fixed object sport parachuting (building, antenna, span, earth (BASE) jumping) and create a basis for prevention. Descriptive epidemiological study. Data on reported fatal injury events (n = 106) worldwide in 1981-2006 retrieved from the BASE fatality list. Human, equipment and environmental factors. Identification of typical fatal incident and injury mechanisms for each of the four fixed object types of BASE jumping (building, antenna, span, earth). Human factors included parachutist free fall instability (loss of body control before parachute deployment), free fall acrobatics and deployment failure by the parachutist. Equipment factors included pilot chute malfunction and parachute malfunction. In cliff jumping (BASE object type E), parachute opening towards the object jumped was the most frequent equipment factor. Environmental factors included poor visibility, strong or turbulent winds, cold and water. The overall annual fatality risk for all object types during the year 2002 was estimated at about one fatality per 60 participants. Participants in BASE jumping should target risk factors with training and technical interventions. The mechanisms described in this study should be used by rescue units to improve the management of incidents.

Substantial literature exists regarding recommendations for the on-field treatment and subsequent transportation of adult collision-sport athletes with a suspected injury to the cervical spine. To develop an evidence-based recommendation for transportation of suspected spine-injured youth football players. Descriptive laboratory study. Three lateral radiographs were obtained in supine to include the occiput to the cervical thoracic junction from 31 youth football players (8-14 years). Each child was imaged while wearing helmet and shoulder pads, without equipment, and with shoulder pads only. Two independent observers measured cervical spine angulation as Cobb angle from C1 to C7 and subaxial angulation from C2 to C7. We calculated intraclass correlation coefficients for intraobserver reliability analysis and compared Cobb and C2 to C7 angles between equipment conditions with t tests. Interobserver analysis showed excellent reliability among measurements. Cobb and subaxial angle measurements indicated significantly greater cervical lordosis while children wore shoulder pads only, compared with the other 2 conditions (no equipment and helmet and shoulder pads) (P .05). Equipment removal for the youth football athlete with suspected cervical spine injury should abide by the "all or none" policy that has been widely accepted for adult athletes. Helmet and shoulder pads should be left in place during emergency transport of the suspected spine-injured youth athlete. Despite differences in head to torso size ratios between youth and adult players, helmet removal alone is not recommended for either during emergency transportation.

Methods: The observation period for this study started on October 1, 2003 and ended on May 1, 2004 and included 30 air rescue missions. Data and information were collected prospectively. Results: The Air Mercy Service in Cape Town Province responded to 30 requests for help. Twenty five accidents were attributed to inability to detach the kite from the harness. Injuries occurred in five incidents and included fractures of the upper arm, ribs and ankle, and lacerations and contusions to the head and neck. Two patients suffered from hypothermia and one experienced severe exhaustion. All surfers were rescued successfully and there were no fatal accidents. Discussion: The risk potential of this new sport is unclear. Dangerous situations can occur despite proper training and safety precautions due to unpredictable conditions and difficulties with equipment. Safety should be stressed. Surfers should sailing with a fellow kiter and should wear a life vest. More efforts must be taken to make this booming new water sport safer. PMID:15849279

To determine whether athletes from different sport disciplines present similar mean propulsive velocity (MPV) in the half-squat (HS) during submaximal and maximal tests, enabling prediction of 1-repetition maximum (1-RM) from MPV at any given submaximal load. Sixty-four male athletes, comprising American football, rugby, and soccer players; sprinters and jumpers; and combat-sport strikers attended 2 testing sessions separated by 2-4 wk. On the first visit, a standardized 1-RM test was performed. On the second, athletes performed HSs on Smith-machine equipment, using relative percentages of 1-RM to determine the respective MPV of submaximal and maximal loads. Linear regression established the relationship between MPV and percentage of 1-RM. A very strong linear relationship (R2 ≈ .96) was observed between the MPV and the percentages of HS 1-RM, resulting in the following equation: %HS 1-RM = -105.05 × MPV + 131.75. The MPV at HS 1-RM was ~0.3 m/s. This equation can be used to predict HS 1-RM on a Smith machine with a high degree of accuracy.

Managing Sports-related Concussions From Time of Injury Through Return to Play.

Shirley, Eric; Hudspeth, L Jared; Maynard, Jennifer R

2018-06-01

Sports-related concussions continue to generate widespread interest. A concussion is a complex pathophysiologic process, with or without loss of consciousness, that results in a disturbance of brain function. Risk factors include age <18 years, female sex, and history of a previous concussion. A sideline physical examination with standardized assessment tools can assist diagnosis. Management for suspected concussion begins with immediate removal from play and requires clinical follow-up. Symptoms are usually self-limited and resolve within 2 to 3 weeks. Initial treatment consists of a reduction in cognitive activity and physical rest. A stepwise return-to-play protocol, taking into consideration state laws, with a gradual increase in activity until the athlete is able to perform full activity without symptoms should be followed. Neuropsychologic testing may be used as a tool in management. For prolonged concussion, physical rehabilitation or medications for headaches, mood, or sleep disturbance may be required. Education, rule changes, and equipment improvements may assist in prevention. The long-term consequences of concussions are not fully understood and merit additional research.

To identify, describe and compare injuries among three water sport activities: kite surfing (KS), personal watercraft (PWC) and towed water sports (TWS). The study was a cross sectional, online survey. The setting was on Perth, Western Australia's popular beaches and riverbanks. Main outcome measures were number of injuries and level of severity; level of exposure and protection measures. Overall, 43% reported at least one injury in the past 12 months, a rate of 22.3 injuries per 100 h. Kite surfers were more likely to report an injury than PWC or TWS. One-half of injuries occurred while on the water. Most injuries were caused by landing awkwardly (56%) and/or trying new tricks (41%). Despite 90% of respondents having used at least one personal protective equipment (PPE) item, half (49%) reported always using a personal floatation device. This study provided information on KS, PWC and TWS injuries as well as a range of safety behaviours. It is recommended that these results form the basis of further research to reduce injury rates and encourage the use of PPE items.

Objectives Powered paragliding (PPG) and paragliding are two totally different sports, mainly because of the use of an engine in powered paragliding. As a consequence, the pattern of injuries caused by each of these two sports may be different. Setting To test this hypothesis, we analysed 384 incident reports gathered by the US Powered Paragliding Association from 1995 to 2012. The majority of the incidents occurred in the USA, while 26 incidents occurred elsewhere: Canada (8), Mexico (5), Panama (1), China (1), Japan (1), Malaysia (1), Indonesia (Java) (1), Europe (8): of which Spain (1), Belgium (1), UK (3), Italy (1), Romania (1), unknown (1). Outcome To identify the most affected body area and the most common type of injury sustained in PPG, and to highlight any differences from paragliding. Results The most affected body areas in PPG were the upper limbs (44.5%), followed by the lower limbs (32%), the back (9.8%), the head (7%), the pelvis (3.1), the chest (2.7%) and the abdomen (0.7%) (p<0.001). The engine caused 43 accidents (11.2%) in our study and was responsible for the majority of injuries to the upper limbs. The number of fatal accidents in PPG is not lower than in paragliding and hang-gliding. Conclusions To help prevent the specific injuries of PPG, the most appropriate equipment should be identified. The results of this study also suggest that, in the future, this sport should be analysed separately from paragliding. PMID:25168039

Mouth protectors and sports team dentists. Bureau of Health Education and Audiovisual Services, Council on Dental Materials, Instruments, and Equipment.

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.

Increasing the probability of surviving loss of consciousness underwater when using a rebreather.

PubMed

Haynes, Paul

2016-12-01

Re-circulating underwater breathing apparatus (rebreathers) have become increasingly popular amongst sport divers. In comparison to open-circuit scuba, rebreathers are complex life support equipment that incorporates many inherent failure modes and potential for human error. This individually or in combination can lead to an inappropriate breathing gas. Analysis of rebreather diving incidents suggests that inappropriate breathing gas is the most prevalent disabling agent. This can result in spontaneous loss of consciousness (LoC), water aspiration and drowning. Protecting the airway by maintaining the diver/rebreather oral interface may delay water aspiration following LoC underwater; the possibility of a successful rescue is, thus, increased. One means of protecting the airway following LoC underwater is the use of a full-face mask (FFM). However, such masks are complex and expensive; therefore, they have not been widely adopted by the sport diving community. An alternative to the FFM used extensively throughout the global military diving community is the mouthpiece retaining strap (MRS). A recent study documented 54 LoC events in military rebreather diving with only three consequent drownings; all divers were reported to be using a MRS. Even allowing for the concomitant use of a tethered diving partner system in most cases, the low number of fatalities in this large series is circumstantially supportive of the efficacy of the MRS. Despite drowning featuring as a final common pathway in the vast majority of rebreather fatalities, the MRS has not been widely adopted by the sport rebreather diving community.

The incidence of acute cardiac events - including out-of-hospital cardiac arrest - may be increased in visitors of large sports stadiums when compared with the general population. This study sought to investigate the incidence of acute cardiac events inside large Dutch football stadiums, as well as the emergency response systems deployed in these stadiums and the success rate for in-stadium resuscitation. Retrospective cohort study using a questionnaire sent to the 20 Dutch stadiums that hosted professional matches during the 2006-2007 and 2007-2008 football seasons. Stadium capacity ranged from 3600 to 51 600 spectators. Nearly 13 million spectators attended 686 'Eredivisie' (Honorary Division) and European football matches. All stadiums distribute multiple emergency medical teams among the spectators. Eighty-five percent of the stadiums have an ambulance standby during matches, 95% of the stadiums were equipped with automated external defibrillators (AEDs) during the study period. On an average, one AED was available for every 7576 spectators (range 1800-29 600). Ninety-three cardiac events were reported (7.3 per 1 million spectators). An AED was used 22 times (1.7 per 1 million spectators). Resuscitation was successful in 18 cases (82%, 95% confidence interval: 61-93). The incidence of out-of-hospital cardiac arrest inside large football stadiums in the Netherlands, albeit increased when compared with the general population, is low. The success rate for in-stadium resuscitation by medical teams equipped with AEDs is high. Dutch stadiums appear vigilant in regard to acute cardiac events. This report highlights the importance of adequate emergency medical response systems (including AEDs) in large sports venues.

Test of the ``radical-like polymerization'' scheme in molecular dynamics on the behavior of polymers under shock loading

The behavior of polymer melts under shock loading is a question attracting more and more attention because of applications such as polymer-bonded explosives, light-weight armor and civilian protective equipment, like sports and car equipment. Molecular dynamics (MD) simulations are a very good tool to characterize the microscopic response of the polymer to a shock wave. To do so, the initial configuration of the polymer melt needs to be realistic. The ``radical-like polymerization'' scheme is a method to obtain near equilibrium configurations of a melt of long polymer chains. It consists in adding one neighboring monomer at a time to each growing chain. Between each polymerization step an MD run is performed to relax the new configuration. We test how details of our implementation of the ``radical-like polymerization'' scheme can impact or not Hugoniot curves and changes of chain configuration under shock. We compare our results to other simulation and experimental results on reference polymers.

Brain injury in sports.

Helmets are used for sports, military, and transportation to protect against impact forces and associated injuries. The common belief among end users is that the helmet protects the whole head, including the brain. However, current consensus among biomechanists and sports neurologists indicates that helmets do not provide significant protection against concussion and brain injuries. In this paper the authors present existing scientific evidence on the mechanisms underlying traumatic head and brain injuries, along with a biomechanical evaluation of 21 current and retired football helmets. The National Operating Committee on Standards for Athletic Equipment (NOCSAE) standard test apparatus was modified and validated for impact testing of protective headwear to include the measurement of both linear and angular kinematics. From a drop height of 2.0 m onto a flat steel anvil, each football helmet was impacted 5 times in the occipital area. Skull fracture risk was determined for each of the current varsity football helmets by calculating the percentage reduction in linear acceleration relative to a 140-g skull fracture threshold. Risk of subdural hematoma was determined by calculating the percentage reduction in angular acceleration relative to the bridging vein failure threshold, computed as a function of impact duration. Ranking the helmets according to their performance under these criteria, the authors determined that the Schutt Vengeance performed the best overall. The study findings demonstrated that not all football helmets provide equal or adequate protection against either focal head injuries or traumatic brain injuries. In fact, some of the most popular helmets on the field ranked among the worst. While protection is improving, none of the current or retired varsity football helmets can provide absolute protection against brain injuries, including concussions and subdural hematomas. To maximize protection against head and brain injuries for football players of all ages, the authors propose thresholds for all sports helmets based on a peak linear acceleration no greater than 90 g and a peak angular acceleration not exceeding 1700 rad/sec(2).

Rugby union football continues to gain in popularity in the United States. Both men's and women's clubs have been established at several colleges and universities. There has been substantial growth in the number of high school rugby football clubs in recent years. With the increase in numbers of young participants in this sport, it is important that great efforts be mounted to attempt to control the injury rates and severity of injuries in rugby football. Players and coaches must be knowledgeable of the rules of the game, and referees must strictly enforce these rules. Physicians and dentists should be involved in educating parents, coaches, players, and school officials about the inherent risks of injury and the means for injury prevention. Medical personnel must also be instrumental in educating players about alcohol abuse/addiction. Rugby players should be encouraged to use the limited protective gear that is allowed: wraps, tape, joint sleeves, scrum caps, and facial grease to prevent lacerations. Mouthguards are strongly recommended at any level of play and should be mandated. The use of helmets, face masks, and shoulder pads has been suggested by some authors. Such rule changes could actually increase injury rates and severity, because this equipment could be used as weapons as they are in American football. It is recommended that rugby clubs purchase or build equipment to practice scrummage skills. Coaches should be experienced and attend clinics or complete video courses on medical emergencies and safe techniques of the game. Injury frequency and severity can be decreased by adequate preseason training and conditioning, proper tackling and falling techniques, strengthening of neck muscles, and allowing only experienced, fit athletes to play in the front row. Medical surveillance must be improved at matches and, ideally, at practice sessions. At present, it is common for no emergency medical personnel or physicians to be present at matches in the United States. Better case registers are necessary to monitor rugby injuries, but more medical professionals must become involved in the sport to obtain useful data. Rugby players will respect the advice of a medical adviser, providing he or she is knowledgeable. This is a hardy group of athletes with a cavalier attitude, as evidenced by the injury statistics and the case studies above. Their sport can be made safer without diminishing the intensity of the game or the camaraderie the players enjoy.

Sport Transition of JPSS VIIRS Imagery for Night-time Applications

The NASA/Short-term Prediction, Research, and Transition (SPoRT) Program and NOAA/Cooperative Institute for Research in the Atmosphere (CIRA) work within the NOAA/Joint Polar Satellite System (JPSS) Proving Ground to demonstrate the unique capabilities of the VIIRS instrument. Very similar to MODIS, the VIIRS instrument provides many high-resolution visible and infrared channels in a broad spectrum. In addition, VIIRS is equipped with a low-light sensor that is able to detect light emissions from the land and atmosphere as well as reflected sunlight by the lunar surface. This band is referred to as the Day-Night Band due to the sunlight being used at night to see cloud and topographic features just as one would typically see in day-time visible imagery. NWS forecast offices that collaborate with SPoRT and CIRA have utilized MODIS imagery in operations, but have longed for more frequent passes of polar-orbiting data. The VIIRS instrument enhances SPoRT collaborations with WFOs by providing another day and night-time pass, and at times two additional passes due to its large swath width. This means that multi-spectral, RGB imagery composites are more readily available to prepare users for their use in GOES-R era and high-resolution imagery for use in high-latitudes is more frequently able to supplement standard GOES imagery within the SPoRT Hybrid GEO-LEO product. The transition of VIIRS also introduces the new Day-Night Band capability to forecast operations. An Intensive Evaluation Period (IEP) was conducted in Summer 2013 with a group of "Front Range" NWS offices related to VIIRS night-time imagery. VIIRS single-channel imagery is able to better analyze the specific location of fire hotspots and other land features, as well as provide a more true measurement of various cloud and aerosol properties than geostationary measurements, especially at night. Viewed within the SPoRT Hybrid imagery, the VIIRS data allows forecasters to better interpret the more frequent, but coarse GOES Imagery. Night-time Microphysics and Dust RGB Imagery provides cloud analysis of cloud height, thickness, and composition in order for operational applications such as separating fog from low clouds, dust plume detection, and determining precipitating clouds in radar-void/ blocked regions. The Day-Night Band has a particular benefit to seeing light from cities, fires, or other emissions as well as the reflection of moonlight off of clouds and smoke plumes, given the right lunar phase and angle. Examples from the VIIRS transition and IEP will be presented.

The game of baseball provides an interesting laboratory for experimenting with mechanical phenomena (there are many good examples in The Physics Teacher, available on Professor Alan Nathan's website, and discussed in Physics of Baseball & Softball). We have developed a lab, for an introductory-level physics course, that investigates many of these phenomena. The lab uses inexpensive, readily available equipment such as wooden baseball bats, baseballs, and actual Major League Baseball data. By the end of the lab, students have revisited many concepts they learned earlier in the semester and come away with an understanding of how to put seemingly disparate ideas together to analyze a fun sport.

Coogan, which showcases creative content applications of commercial stereoscopic video equipment. For production, a complete equipment package including a Steadicam mount was used in support of the Ikegami LK-33 camera. Remote production units were fielded in the time critical, on-stage and off-stage environments of 2 major live concerts: Peter Gabriel's Secret World performance at the San Diego Sports Arena, and Cirque du Soleil's Saltimbanco performance in Chicago. Twin 60 Hz video channels were captured on Beta SP for maximum post production flexibility. Digital post production and field sequential mastering were effected in D-2 format at studio facilities in Los Angeles. The program was world premiered to a large public at the World of Music, Arts and Dance festivals in Los Angeles and San Francisco, in late 1993. It was presented to the artists in Los Angeles, Montreal and Washington D.C. Additional presentations have been made using a broad range of commercial and experimental stereoscopic video equipment, including projection systems, LCD and passive eyewear, and digital signal processors. Technical packages for live presentation have been fielded on site and off, through to the present.

Background Stand-up paddle-boarding is an increasingly popular water sport; however no published data to our knowledge exists on the nature and type of injuries sustained in this sport. Objectives This study aims to describe the frequency, pattern, and mechanism of paddle-boarding injuries. Materials and Methods Descriptive data of paddle-boarding injuries were collected using an interactive website-based, multiple-choice survey. Data were collected from May 2012 over a 6-month period. Results Completed surveys were obtained from 142 individuals, 20 paddle-boarders reporting 18 injuries and 122 surfers reporting 4 paddleboard-related injuries. Fifty percent of responding paddle-boarders reported an injury. For all injuries sustained paddle-boarding, sprains accounted for 50% (n = 9), lacerations for 22% (n = 4), contusions 17% (n = 3) and fractures 5% (n = 1). Seventy-eight percent of injuries were to the lower extremity, and 17% to the head and neck. Seventeen percent (n = 3) sustained recurrent injuries, 2 sustained 2 twisting knee injuries resulting in sprains, one sustained > 3 ankle injuries, resulting in sprains. Seventeen percent of injuries resulted from contact with one’s own paddle-board, 17% from another paddle-board, and 5% from the sea floor. Conclusions All paddle-boarding injuries were sustained by individuals who surf waves on a paddle-board, rather than paddle on calm water. Despite concerns, paddle-board related injuries only accounted for 1% of 326 injuries suffered by surfers. We suggest equipment and practice modifications that may decrease the risk for injury and challenge the anecdotal theory that paddle-boarding injuries are sustained due to inexperience.

Kayak racing has been an Olympic sport since 1936. The sport is evolving with the introduction of ocean skis and stand-up-paddle boards (SUP). Musculoskeletal injury incidence surveys have been conducted for ultra-marathon events, but no data have been published for other racing formats. To identify and compare the rates and types of injuries sustained by paddling athletes as a function of discipline and training parameters in Sprint, Marathon, Ultra-Marathon, and Ocean events. Competitors from 6 kayak and/or ocean surf-ski races in Australia were surveyed. Before each race, competitors were asked to complete a questionnaire. The questionnaire investigated paddling-related injuries over the previous 5 years, athlete morphology, flexibility, equipment and its setup, training volume, and environment. Five hundred eighty-three competitors were surveyed. Disciplines included 173 racing-kayak (K1), 202 touring-kayak, 146 ocean-skis, 42 SUP, and 20 other. The top 5 paddling-related injuries were shoulder (31%), low back (23.5%), wrist (16.5%), neck (13.7%), and elbow (11.0%). The highest percentage of injury was found in K1 paddlers for shoulder (40.5%), SUP for low back (33.3%), and ocean-ski for wrist (22.6%). After controlling for on-water training hours, the relative risk (RR) of wrist injury was significantly increased in ocean-ski paddlers (1.86) and in paddlers with decreased flexibility (1.53-1.83). Relative risk of shoulder and low-back injury was significantly increased in athletes with lower training volumes (1.82-2.07). Younger athletes had lower RR of wrist and shoulder injury (0.58-0.62).

The main aim of the study was to design a new system to measure punching and kicking forces as well as reaction times in combat sport athletes. In addition, the study examined whether there were any intergender differences in the force of punches thrown by boxers and kicking forces delivered by taekwondo athletes. Boxers (male, n = 13; female, n = 7) were examined for the force of single straight punches and taekwondo athletes (male, n = 14; female, n = 14) for force of single Apdolio and Dwit Chagi kicks. The punching bag was equipped with acceleration transducers and gyroscopes embedded in a cylinder covered with a layer to absorb shock as well as a set of colour signal diodes. Value of the punching bag's acceleration was used for calculating: strike force; the punching location on the bag; and time of a strike. The relative error of force calculation was 3%; the relative error in acceleration measurement was less than 1%. The force of a straight rear-hand punch was greater than the force of a lead-hand punch among male and female boxers. The force of Apdolio kick delivered with a rear leg was greater compared to a lead leg among female and male taekwondo athletes. Significant gender differences were noticed in the force in both types of kicks. In boxers, intergender differences were reported only for the force of a punch thrown with the rear hand. Based on these findings, it was concluded that the modified punching bag is a good diagnostic tool for combat sports.

Preparedness for practice has become an international theme within Medical Education: for healthcare systems to maintain their highest clinical standards, junior doctors must "hit the ground running" on beginning work. Despite demonstrating logical, structured assessment and management plans during their undergraduate examinations, many newly qualified doctors report difficulty in translating this theoretical knowledge into the real clinical environment. "Preparedness" must constitute more than the knowledge and skills acquired during medical school. Complexities of the clinical environment overwhelm some junior doctors, who acknowledge that they lack strategies to manage their anxieties, under-confidence and low self-efficacy. If uncontrolled, such negative emotions and behaviors may impede the delivery of time-critical treatment for acutely unwell patients and compound junior doctors' self-doubt, thus impacting future patient encounters. Medical Education often seeks inspiration from other industries for potential solutions to challenges. To address "preparedness for practice," this AMEE Guide highlights sport psychology: elite sportspeople train both physically and psychologically for their discipline. The latter promotes management of negative emotions, distractions and under-confidence, thus optimizing performance despite immense pressures of career-defining moments. Similar techniques might allow junior doctors to optimize patient care, especially within stressful situations. This AMEE Guide introduces the novel conceptual model, PERFORM, which targets the challenges faced by junior doctors on graduation. The model applies pre-performance routines from sport psychology with the self-regulatory processes of metacognition to the clinical context. This model could potentially equip junior doctors, and other healthcare professionals facing similar challenges, with strategies to optimize clinical care under the most difficult circumstances.

Hypofrontality is a state of decreased cerebral blood flow in the prefrontal cortex during executive function performance; it is commonly observed in patients with schizophrenia. Cognitive dysfunction, as well as the psychological symptoms of schizophrenia, influences the ability of patients to reintegrate into society. The current study investigated the effects of an interactive sports video game (IVG; Nintendo Wii™ Sports Resort) on frontal lobe function of patients with schizophrenia. A sample of eight patients (6 male and 2 female; mean age = 46.7 years, standard deviation (SD) = 13.7) engaged in an IVG every week for 3 months in a controlled, single-blind, crossover study. Before and after the intervention we examined frontal lobe blood-flow volume using functional near-infrared spectroscopy (fNIRS), and assessed functional changes using the Frontal Assessment Battery, Health-Related Quality of Life scale, and behaviorally-assessed physical function tests. fNIRS revealed that prefrontal activity during IVG performance significantly increased in the IVG period compared with the control period. Furthermore, significant correlations between cerebral blood flow changes in different channels were observed during IVG performance. In addition, we observed intervention-related improvement in health-related quality of life following IVG. IVG intervention was associated with increased prefrontal cortex activation and improved health-related quality of life performance in patients with schizophrenia. Patients with chronic schizophrenia are characterized by withdrawal and a lack of social responsiveness or interest in others. Interventions using IVG may provide a useful low-cost rehabilitation method for such patients, without the need for specialized equipment.

Training equipment used by professional sportsmen has a great impact on their sport performance. Most universal exercisers may help only to improve the general physical condition due to the specific kinematics and peculiar resistance generated by their loading units. Training of effective techniques and learning of psychomotor skills are possible only when exercisers conform to the movements and resistance typical for particular sports kinematically and dynamically. Methodology of developing a magnetorheological resistive exercise device for generating the desired law of passive resistance force and its application in a lever-type rowing machine are described in the paper. The structural parameters of a controllable hydraulic cylinder type device were found by means of the computational fluid dynamics simulation performed by ANSYS CFX software. Parameters describing the magnetorheological fluid as non-Newtonian were determined by combining numerical and experimental research of the resistance force generated by the original magnetorheological damper. A structural scheme of the device control system was developed and the variation of the strength of magnetic field that affects the magnetorheological fluid circulating in the device was determined, ensuring a variation of the resistance force on the oar handle adequate for the resistance that occurs during a real boat rowing stroke.

Three cases of athlete's nodule on the feet are reported. In case 1, a 30-year-old man, who had been an amateur football player, presented with nodules on the lateral side of the feet and on the right lateral malleolus with a duration of 1 year. In case 2, a 22-year-old man, who had participated in karate and track-and-field, presented with nodules on the lateral side of the feet and on the right lateral malleolus with a duration of 10 years. In case 3, a 25-year-old man, who had skied, presented with a nodule on the right lateral malleolus with a duration of 4 years. The biopsy specimens from the lesion demonstrated hyperkeratosis, acanthosis of the epidermis and thickness of the dermis. In 1991, Cohen et al. proposed the concept of athlete's nodule which indicated an acquired cutaneous nodule caused by chronic stimuli with sports. Histopathology of the athlete's nodule shows hypertrophy of the epidermis and dermis. To the best of our knowledge the term "athlete's nodule" has not been used in Japan, but it is a useful term to refer to the lesion induced by athletics or the use of sporting equipment.

Every new competitive season offers excellent examples of human locomotor abilities, regardless of the sport. As a natural consequence of competitions, world records are broken every now and then. World record races not only offer spectators the pleasure of watching very talented and highly trained athletes performing muscular tasks with remarkable skill, but also represent natural models of the ultimate expression of human integrated muscle biology, through strength, speed, or endurance performances. Given that humans may be approaching our species limit for muscular power output, interest in how athletes improve on world records has led to interest in the strategy of how limited energetic resources are best expended over a race. World record performances may also shed light on how athletes in different events solve exactly the same problem-minimizing the time required to reach the finish line. We have previously applied mathematical modeling to the understanding of world record performances in terms of improvements in facilities/equipment and improvements in the athletes' physical capacities. In this commentary, we attempt to demonstrate that differences in world record performances in various sports can be explained using a very simple modeling process.

Stereoscopic filming for investigating evasive side-stepping and anterior cruciate ligament injury risk

NASA Astrophysics Data System (ADS)

Lee, Marcus J. C.; Bourke, Paul; Alderson, Jacqueline A.; Lloyd, David G.; Lay, Brendan

2010-02-01

Non-contact anterior cruciate ligament (ACL) injuries are serious and debilitating, often resulting from the performance of evasive sides-stepping (Ssg) by team sport athletes. Previous laboratory based investigations of evasive Ssg have used generic visual stimuli to simulate realistic time and space constraints that athletes experience in the preparation and execution of the manoeuvre. However, the use of unrealistic visual stimuli to impose these constraints may not be accurately identifying the relationship between the perceptual demands and ACL loading during Ssg in actual game environments. We propose that stereoscopically filmed footage featuring sport specific opposing defender/s simulating a tackle on the viewer, when used as visual stimuli, could improve the ecological validity of laboratory based investigations of evasive Ssg. Due to the need for precision and not just the experience of viewing depth in these scenarios, a rigorous filming process built on key geometric considerations and equipment development to enable a separation of 6.5 cm between two commodity cameras had to be undertaken. Within safety limits, this could be an invaluable tool in enabling more accurate investigations of the associations between evasive Ssg and ACL injury risk.

There is accumulating evidence supporting a link between alcohol industry sponsorship and alcohol-related problems in both community and elite-level sports. Little is known, however, about the current status of such sponsorship, particularly of community sport. This study aimed to assess associations between alcohol industry sponsorship and different community football clubs in Australia. The study involved 101 community football clubs across New South Wales, Australia. One representative from each club took part in a cross-sectional telephone survey designed to assess club (football code, number of players, socioeconomic and geographic descriptors) and alcohol industry sponsorship (money, equipment, free alcohol or discounted alcohol) characteristics. Chi-square analysis was used to test associations between club characteristics, and: i) any alcohol industry sponsorship; and ii) type of sponsorship. Eighty-eight per cent of clubs reported receiving sponsorship from the alcohol industry, and most clubs (82%) were sponsored by a licensed premises. There were no significant associations between club characteristics and source of alcohol industry sponsorship. However, small clubs were found to be significantly more likely to receive free or discounted alcohol sponsorship than larger clubs (p=0.05). This exploratory study suggests a significant presence of alcohol industry sponsorship among community football clubs in Australia.

Off road mountain biking is now an extremely popular recreation and a potent cause of serious injury. To establish the morbidity associated with this sport. Data were collected prospectively over one year on all patients presenting with an injury caused by either recreational or competitive off road mountain biking. Eighty four patients were identified, 70 males and 14 females, with a mean age of 22.5 years (range 8-71). Most accidents occurred during the summer months, most commonly in August. Each patient had an average of 1.6 injuries (n = 133) and these were divided into 15 categories, ranging from minor soft tissue to potentially life threatening. Operative intervention was indicated for 19 patients (23%) and several required multiple procedures. The commonest injuries were clavicle fractures (13%), shoulder injuries (12%), and distal radial fractures (11%). However, of a more sinister nature, one patient had a C2/3 dislocation requiring urgent stabilisation, one required a chest drain for a haemopneumothorax, and another required an emergency and life saving nephrectomy. This sport has recently experienced an explosion in popularity, and, as it carries a significant risk of potentially life threatening injury across all levels of participation, the use of protective equipment to reduce this significant morbidity may be advisable.

Thermoregulation, Fluid Balance, and Sweat Losses in American Football Players.

Numerous studies have reported on the thermoregulation and hydration challenges athletes face in team and individual sports during exercise in the heat. Comparatively less research, however, has been conducted on the American Football player. Therefore, the purpose of this article is to review data collected in laboratory and field studies and discuss the thermoregulation, fluid balance, and sweat losses of American Football players. American Football presents a unique challenge to thermoregulation compared with other sports because of the encapsulating nature of the required protective equipment, large body size of players, and preseason practice occurring during the hottest time of year. Epidemiological studies report disproportionately higher rates of exertional heat illness and heat stroke in American Football compared with other sports. Specifically, larger players (e.g., linemen) are at increased risk for heat ailments compared with smaller players (e.g., backs) because of greater body mass index, increased body fat, lower surface area to body mass ratio, lower aerobic capacity, and the stationary nature of the position, which can reduce heat dissipation. A consistent finding across studies is that larger players exhibit higher sweating rates than smaller players. Mean sweating rates from 1.0 to 2.9 L/h have been reported for college and professional American Football players, with several studies reporting 3.0 L/h or more in some larger players. Sweat sodium concentration of American Football players does not seem to differ from that of athletes in other sports; however, given the high volume of sweat loss, the potential for sodium loss is higher in American Football than in other sports. Despite high sweating rates with American Football players, the observed disturbances in fluid balance have generally been mild (mean body mass loss ≤2 %). The majority of field-based studies have been conducted in the northeastern part of the United States, with limited studies in different geographical regions (i.e., southeast) of the United States. Further, there have been a limited number of studies examining body core temperature of American Football players during preseason practice, especially at the high school level. Future field-based research in American Football with various levels of competition in hotter geographical regions of the United States is warranted.

The science of fencing: implications for performance and injury prevention.

PubMed

Roi, Giulio S; Bianchedi, Diana

2008-01-01

In this review we analyse the data from the literature on fencing with the aim of creating a psychobiological and multi-factorial model of fencing performance. Fencing is an open-skilled combat sport that was admitted to the first modern Olympic Games in Athens (1896). It is mainly practised indoors, with three different weapons: the foil, the sabre and the épée, each contested with different rules. A fencing international tournament may last between 9 and 11 hours. Bouts represent only 18% of total competition time, with an effective fight time of between 17 and 48 minutes. The physical demands of fencing competitions are high, involving the aerobic and anaerobic alactic and lactic metabolisms, and are also affected by age, sex, level of training and technical and tactical models utilized in relation to the adversary. The anthropometrical characteristics of fencers show a typical asymmetry of the limbs as a result of the practice of an asymmetrical sport activity. Fencing produces typical functional asymmetries that emphasize the very high level of specific function, strength and control required in this sport. Moreover, the physical demands of fencing are closely linked to the perceptual and psychological ones, and all are subjected to a continuous succession of changes during the bouts based on the behaviour of the opponent. For this reason it is difficult to identify a significant relationship between any one physiological characteristic and performance, and performance is more likely to be influenced by perceptual and neuro-physiological characteristics. Fencers need to anticipate the opponent and to mask their true intentions with a game of feints and counter-feints, which must be supported by an adequate psycho-physical condition to prevent central and peripheral fatigue. Fencing is not particularly dangerous; however, there is a fine line between a fatal lesion and a simple wound from a broken blade. The suggestions for injury prevention fall into three primary areas: (i) actions that can be taken by participants; (ii) improvements in equipment and facilities; and (iii) administration of fencing competitions. As in every other sport, the prevention of accidents must be accomplished at various levels and above all must involve the institutions that are responsible for safety in sports.

Enacted in 1937, the Federal Aid in Wildlife Restoration Act – more commonly known as the Pittman-Robertson Act – is one of the oldest and most reliable sources of funding for wildlife conservation in the United States. The result of organized support form sportsmen, fish and wildlife agencies, firearms manufacturers, conservation organizations, and even garden clubs, the PR Act created an excise tax on so-called “long guns” and ammunition used by hunters, thereby establishing the first sustainable source of revenue dedicated to conservation and land management efforts throughout the country. Later, legislators amended the PR Act to include an excise tax on pistols, revolvers, bows, arrows, and other archery equipment.

The purpose of this study was to examine the use of home exercise equipment in the form of exergame cycling compared to a stationary recumbent bicycle ergometer in front of TV in the home over 3 months among parents of an intervention with their inactive children. The primary outcome was bike use (total weekly duration). Predictors of bike use in the form of theory of planned behavior and self-determination theory were also examined. Randomized controlled trial. Sixty eight parents of children aged 10-14 were randomized to either the exergame condition (n=36) or the standard bike condition (n=32). Weekly bike use was recorded in a log-book. The exergame bike and a standard bike in front of a TV had similar use across three months (p=.13, η p 2 =.02), which declined over time (p<.01, η p 2 =.14). Parents who were active at baseline and had the intention to use the bikes were more likely to use the bikes (p<.05). Furthermore, those who reported higher perceived control, intrinsic motivation, and affective attitude were more likely to use the bikes (p<.05). The findings suggested that irrespective of modality, use of exercise equipment declined considerably for parents over three-months. Parents may also benefit from family physical activity interventions, but it depends on their physical activity status, how much they would enjoy using the equipment, and their overall perceived control over being physically active. clinicaltrials.gov #NCT01373762.

BACKGROUND Repeated head trauma has been associated with risk of neurodegenerative diseases. Few studies have evaluated the long-term risk of neurodegenerative diseases in collision sports like football. OBJECTIVE To assess whether athletes who played American varsity high-school football between 1956 and 1970 have an increased risk of neurodegenerative diseases later in life. PATIENTS AND METHODS We identified all male varsity football players between 1956 and 1970 in the public high schools of Rochester, Minnesota, compared to non-football-playing male varsity swimmers, wrestlers or basketball players. Using the records-linkage system of the Rochester Epidemiology Project, we ascertained the incidence of late-life neurodegenerative diseases: dementia, parkinsonism, or amyotrophic lateral sclerosis. We also recorded medical record-documented head trauma during high school years. RESULTS We identified 296 varsity football players and 190 athletes engaging in other sports. Football players had an increased risk of medically documented head trauma, especially if they played football for more than one year. Compared to non-football athletes, football players did not have an increased risk of neurodegenerative disease overall, nor the individual conditions of dementia, parkinsonism, or amyotrophic lateral sclerosis. CONCLUSION In this community based study, varsity high school football players from 1956 to 1970 did not have an increased risk of developing neurodegenerative diseases compared with athletes engaged in other varsity sports. This was from an era where there was a generally nihilistic view of concussion dangers, less protective equipment and without prohibition of spearing (head-first tackling). However, size and strength of players from prior eras may not be comparable to current high-school athletes. PMID:27979411

Artificial intelligence in sports on the example of weight training.

Novatchkov, Hristo; Baca, Arnold

2013-01-01

The overall goal of the present study was to illustrate the potential of artificial intelligence (AI) techniques in sports on the example of weight training. The research focused in particular on the implementation of pattern recognition methods for the evaluation of performed exercises on training machines. The data acquisition was carried out using way and cable force sensors attached to various weight machines, thereby enabling the measurement of essential displacement and force determinants during training. On the basis of the gathered data, it was consequently possible to deduce other significant characteristics like time periods or movement velocities. These parameters were applied for the development of intelligent methods adapted from conventional machine learning concepts, allowing an automatic assessment of the exercise technique and providing individuals with appropriate feedback. In practice, the implementation of such techniques could be crucial for the investigation of the quality of the execution, the assistance of athletes but also coaches, the training optimization and for prevention purposes. For the current study, the data was based on measurements from 15 rather inexperienced participants, performing 3-5 sets of 10-12 repetitions on a leg press machine. The initially preprocessed data was used for the extraction of significant features, on which supervised modeling methods were applied. Professional trainers were involved in the assessment and classification processes by analyzing the video recorded executions. The so far obtained modeling results showed good performance and prediction outcomes, indicating the feasibility and potency of AI techniques in assessing performances on weight training equipment automatically and providing sportsmen with prompt advice. Key pointsArtificial intelligence is a promising field for sport-related analysis.Implementations integrating pattern recognition techniques enable the automatic evaluation of data measurements.Artificial neural networks applied for the analysis of weight training data show good performance and high classification rates.

Mixed martial arts (MMA) is currently the fastest growing sport in the United States and has recently surpassed boxing as the most popular full contact sport. Due to the physical nature of the sport, MMA is associated with various types of injuries. The purpose of this study was aimed at identifying prevalence and assessing the severity, location, and type of injuries in MMA athletes sustained during MMA related activities in the twelve month period prior to the survey. A total of fifty-five subjects between the ages of 18 to 39 participated in the study. Participants were given a two-part questionnaire to collect demographic and injury data. Two hundred seven injuries were reported in the study. Low belt ranks had significantly more injuries more than any other belt rank, resulting in more than two times higher injury rate. Professional fighters had significantly more injuries than amateur fighters, resulting in three times higher injury rate. The most common body region injured was the head/neck/face (38.2%), followed by the lower extremities (30.4%), upper extremities (22.7%), torso (8.2%), and groin (0.5%). Injuries to the nose (6.3%), shoulder (6.3%), and toe (6.3%) were the most common. The most common type of injury was contusions (29.4%), followed by strains (16.2%), sprains (14.9%), and abrasions (10.1%). Injury prevention efforts should consider the prevalence and distribution of injuries and focus on reducing or preventing injuries to the head/neck/face in MMA related activities. Preventative measures should focus on improving protective equipment during training, and possible competition rule modifications to further minimize participant injury.

Merits of Undergraduate and High School Research

When it comes to sports, everyone gets it; you have to play to really understand, experience, and learn what the game is all about. It would be ludicrous to teach basketball by practicing basketball fundamentals in the gym (layups, free throws, jump shots, dribbling, defense), reading about and attending professional basketball games, but never playing in a game. As important as classes and teaching laboratories may be in science education, there is simply no substitute for active engagement in scientific research to show students what science is all about and, perhaps even more importantly, to inspire and motivate them to become scientists or at least appreciate science. It is a widely held misconception that a student cannot really do meaningful, publishable scientific research until he/she is in graduate school. In actual fact, college undergraduates and even high school students can make original and significant scientific research contributions. Astronomical research, in particular, is very well suited to engage the beginning high school or college undergraduate researcher. The night sky’s inherent accessibility and also its inherent grandeur are natural draws for the curious student’s mind. And much can be learned and discovered using small telescopes. In sports, joining a team is a key aspect of the sports experience. Similarly in science, joining a research team and thereby entering a “community of scientific practice” is fundamental and transformational. As important as working with equipment and acquiring data happen to be in scientific research, this is only the beginning of the research process. Student researchers of all ages—particularly high school students and college undergraduates—have much to gain by giving presentations on their research, writing up their results for publication, and going through the peer review process. But this only works if the student researchers are imbedded within the community of practice.

Determining the Prevalence and Assessing the Severity of Injuries in Mixed Martial Arts Athletes

PubMed Central

2009-01-01

Background Mixed martial arts (MMA) is currently the fastest growing sport in the United States and has recently surpassed boxing as the most popular full contact sport. Due to the physical nature of the sport, MMA is associated with various types of injuries. Objective The purpose of this study was aimed at identifying prevalence and assessing the severity, location, and type of injuries in MMA athletes sustained during MMA related activities in the twelve month period prior to the survey. Methods A total of fifty-five subjects between the ages of 18 to 39 participated in the study. Participants were given a two-part questionnaire to collect demographic and injury data. Results Two hundred seven injuries were reported in the study. Low belt ranks had significantly more injuries more than any other belt rank, resulting in more than two times higher injury rate. Professional fighters had significantly more injuries than amateur fighters, resulting in three times higher injury rate. The most common body region injured was the head/neck/face (38.2%), followed by the lower extremities (30.4%), upper extremities (22.7%), torso (8.2%), and groin (0.5%). Injuries to the nose (6.3%), shoulder (6.3%), and toe (6.3%) were the most common. The most common type of injury was contusions (29.4%), followed by strains (16.2%), sprains (14.9%), and abrasions (10.1%). Conclusion Injury prevention efforts should consider the prevalence and distribution of injuries and focus on reducing or preventing injuries to the head/neck/face in MMA related activities. Preventative measures should focus on improving protective equipment during training, and possible competition rule modifications to further minimize participant injury. PMID:21509103

Artificial Intelligence in Sports on the Example of Weight Training

Novatchkov, Hristo; Baca, Arnold

2013-01-01

The overall goal of the present study was to illustrate the potential of artificial intelligence (AI) techniques in sports on the example of weight training. The research focused in particular on the implementation of pattern recognition methods for the evaluation of performed exercises on training machines. The data acquisition was carried out using way and cable force sensors attached to various weight machines, thereby enabling the measurement of essential displacement and force determinants during training. On the basis of the gathered data, it was consequently possible to deduce other significant characteristics like time periods or movement velocities. These parameters were applied for the development of intelligent methods adapted from conventional machine learning concepts, allowing an automatic assessment of the exercise technique and providing individuals with appropriate feedback. In practice, the implementation of such techniques could be crucial for the investigation of the quality of the execution, the assistance of athletes but also coaches, the training optimization and for prevention purposes. For the current study, the data was based on measurements from 15 rather inexperienced participants, performing 3-5 sets of 10-12 repetitions on a leg press machine. The initially preprocessed data was used for the extraction of significant features, on which supervised modeling methods were applied. Professional trainers were involved in the assessment and classification processes by analyzing the video recorded executions. The so far obtained modeling results showed good performance and prediction outcomes, indicating the feasibility and potency of AI techniques in assessing performances on weight training equipment automatically and providing sportsmen with prompt advice. Key points Artificial intelligence is a promising field for sport-related analysis. Implementations integrating pattern recognition techniques enable the automatic evaluation of data measurements. Artificial neural networks applied for the analysis of weight training data show good performance and high classification rates. PMID:24149722

The American Medical Society for Sports Medicine (AMSSM) developed a musculoskeletal ultrasound curriculum for sports medicine fellowships in 2010. As the use of diagnostic and interventional ultrasound in sports medicine has evolved, it became clear that the curriculum needed to be updated. Furthermore, the name 'musculoskeletal ultrasound' was changed to 'sports ultrasound' (SPORTS US) to reflect the broad range of diagnostic and interventional applications of ultrasound in sports medicine. This document was created to outline the core competencies of SPORTS US and to provide sports medicine fellowship directors and others interested in SPORTS US education with a guide to create a SPORTS US curriculum. By completing this SPORTS US curriculum, sports medicine fellows and physicians can attain proficiency in the core competencies of SPORTS US required for the practice of sports medicine.

Objective: To review 16 years of National Collegiate Athletic Association (NCAA) injury surveillance data for men's football and identify potential areas for injury prevention initiatives. Background: Football is a high-velocity collision sport in which injuries are expected. Football tends to have one of the highest injury rates in sports. Epidemiologic data helps certified athletic trainers and other clinicians identify injury trends and patterns to appropriately design and institute injury prevention protocols and then measure their effects. Main Results: During the 16-year reporting period, about 19% of the Division I, II, and III NCAA institutions sponsoring football participated in the Injury Surveillance System. The results from the 16-year study period show little variation in the injury rates over time: games averaged 36 injuries per 1000 athlete-exposures (A-Es); fall practice, approximately 4 injuries per 1000 A-Es; and spring practice, about 10 injuries per 1000 A-Es. The game injury rate was more than 9 times higher than the in-season practice injury rate (35.90 versus 3.80 injuries per 1000 A-Es, rate ratio = 9.1, 95% confidence interval = 9.0, 9.2), and the spring practice injury rate was more than 2 times higher than the fall practice injury rate (9.62 versus 3.80 injuries per 1000 A-Es, rate ratio = 2.5, 95% confidence interval = 2.5, 2.6). The rate ratio for games versus fall practices was greatest for upper leg contusions (18.1 per 1000 A-Es), acromioclavicular joint sprains (14.0 per 1000 A-Es), knee internal derangements (13.4 per 1000 A-Es), ankle ligament sprains (12.0 per 1000 A-Es), and concussions (11.1 per 1000 A-Es). Recommendations: Football is a complex sport that requires a range of skills performed by athletes with a wide variety of body shapes and types. Injury risks are greatest during games. Thus, injury prevention measures should focus on position-specific activities to reduce the injury rate. As equipment technology improves for the helmet, shoulder pads, and other protective devices, appropriate injury surveillance procedures should be performed to determine the effect of the new equipment on injury rates. A consistent evaluation of injury trends and patterns will assist decision makers in designing injury prevention techniques in areas that warrant the greatest attention and suggesting rule changes and modifications based on the data.

Anterior cruciate ligament injury/reinjury in alpine ski racing: a narrative review

PubMed Central

Jordan, Matthew J; Aagaard, Per; Herzog, Walter

2017-01-01

The purpose of the present review was to: 1) provide an overview of the current understanding on the epidemiology, etiology, risk factors, and prevention methods for anterior cruciate ligament (ACL) injury in alpine ski racing; and 2) provide an overview of what is known pertaining to ACL reinjury and return to sport after ACL injury in alpine ski racing. Given that most of the scientific studies on ACL injuries in alpine ski racing have been descriptive, and that very few studies contributed higher level scientific evidence, a nonsystematic narrative review was employed. Three scholarly databases were searched for articles on ACL injury or knee injury in alpine ski racing. Studies were classified according to their relevance in relation to epidemiology, etiology, risk factors, and return to sport/reinjury prevention. Alpine ski racers (skiers) were found to be at high risk for knee injuries, and ACL tears were the most frequent diagnosis. Three primary ACL injury mechanism were identified that involved tibial internal rotation and anteriorly directed shear forces from ski equipment and the environment. While trunk muscle strength imbalance and genetics were found to be predictive of ACL injuries in development-level skiers, there was limited scientific data on ACL injury risk factors among elite skiers. Based on expert opinion, research on injury risk factors should focus on equipment design, course settings/speed, and athlete factors (eg, fitness). While skiers seem to make a successful recovery following ACL injury, there may be persistent neuromuscular deficits. Future research efforts should be directed toward prospective studies on ACL injury/reinjury prevention in both male and female skiers and toward the effects of knee injury on long-term health outcomes, such as the early development of osteoarthritis. International collaborations may be necessary to generate sufficient statistical power for ACL injury/reinjury prevention research in alpine ski racing. PMID:28435336

Studies on the relation between the social neighborhood environment and sports participation have produced inconsistent results. Use of generic sports outcomes may have obscured associations only apparent for sports at certain locations. This study aims to assess the association between the social neighborhood environment and three location-specific sports outcomes. Repeated cross-sectional data on sports participation (any type of sports, sports at indoor sports clubs, sports at outdoor sports clubs, sports on streets) were obtained from 20 600 adults using the Dutch national health survey 2006-2009. Data on neighborhood social safety and social capital were obtained using the Dutch Housing Research 2006. Over 40% of Dutch adults participated in any type of sports. Indoor sports clubs were most popular. Multilevel logistic regression analyses revealed that neighborhood social safety was positively associated with sports at indoor sports clubs [odds ratio (OR) = 1.25, 95% confidence interval (CI) = 1.06-1.48), but not with the other sports outcomes. Contrary, neighborhood social capital was positively associated with sports on streets only (OR = 1.69, 95% CI = 1.17-2.44). The results suggest that a positive social neighborhood environment enhances sports participation, but that this impact depends on the location of the sports activity. This study highlights the importance of using location-specific sports outcomes when assessing environmental determinants. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Do objective neighbourhood characteristics relate to residents' preferences for certain sports locations? A cross-sectional study using a discrete choice modelling approach.

The number of sports facilities, sports clubs, or city parks in a residential neighbourhood may affect the likelihood that people participate in sports and their preferences for a certain sports location. This study aimed to assess whether objective physical and socio-spatial neighbourhood characteristics relate to sports participation and preferences for sports locations. Data from Dutch adults (N = 1201) on sports participation, their most-used sports location, and socio-demographic characteristics were collected using an online survey. Objective land-use data and the number of sports facilities were gathered for each participant using a 2000-m buffer around their home locations, whereas socio-spatial neighbourhood characteristics (i.e., density, socio-economic status, and safety) were determined at the neighbourhood level. A discrete choice-modelling framework (multinomial probit model) was used to model the associations between neighbourhood characteristics and sports participation and location. Higher proportions of green space, blue space, and the number of sports facilities were positively associated with sports participation in public space, at sports clubs, and at other sports facilities. Higher degrees of urbanization were negatively associated with sports participation at public spaces, sports clubs, and other sports facilities. Those with more green space, blue space or sports facilities in their residential neighbourhood were more likely to participate in sports, but these factors did not affect their preference for a certain sports location. Longitudinal study designs are necessary to assess causality: do active people choose to live in sports-facilitating neighbourhoods, or do neighbourhood characteristics affect sports participation?

The aim of the present study was to explore the relationship between stress and sport performance in a controlled setting. The experimental protocol used to induce stress in a basketball free throw was the Trier Social Stress Test (TSST) and its control condition (Placebo-TSST). Participants (n = 19), novice basketball players but trained sportspersons, were exposed to two counterbalanced conditions in a crossover design. They were equipped with sensors to measure movement execution, while salivary cortisol and psychological state were also measured. The task consisted of two sequences of 40 free throws, one before either the TSST or Placebo-TSST and one after. Physiological and psychological measures evidenced that the TSST induced significant stress responses, whereas the Placebo-TSST did not. Shooting performance remained stable after the TSST but decreased after the Placebo-TSST. We found no effect of the TSST or Placebo-TSST on movement execution. A multivariate model of free throw performance demonstrated that timing, smoothness and explosiveness of the movements are more relevant to account for beginner’s behavior than stress-related physiological and psychological states. We conclude that the TSST is a suitable protocol to induce stress responses in sport context, even though the effects on beginners’ free throw performance and execution are small and complex.

Maroon, Joseph C; Mathyssek, Christina; Bost, Jeffrey

No topic in sports has gathered more attention and publicity than the diagnosis, management, and long-term effects of cerebral concussion. The relevant history of concussion starts in 1905 when President Theodore Roosevelt drew attention to the football 'death harvest'. Soon after, rules started to change to reduce the amount and severity of head injuries in football. Up until 1980, the primary focus regarding concussions was to diagnose a potentially fatal intracranial hemorrhage. While aware of long-term consequences of concussions, the perception at the time was that virtually all concussions would 'clear' with time and rest. Concussion management guidelines gave way to objective neuropsychological testing in the early 1990s with the development of the ImPACT™ (Immediate Post-Concussion Assessment and Cognitive Testing) neurocognitive test. Led by organized football, in 1994 the National Football League (NFL) formed the Mild Traumatic Brain Injury Committee which began to investigate the cause of concussions, evaluate equipment (particularly helmets), and recommend methods for prevention. In 2005, the first case of chronic traumatic encephalopathy was described in a deceased football player, raising concerns about the long-term consequences of head injuries and concussions. Major advancements in contact sports and the military are underway to reduce the incidence of concussions and subconcussive blows to the head. © 2014 S. Karger AG, Basel.

Burke, D; Barfoot, K; Bryant, S; Schneider, J; Kim, H; Levin, G

2003-01-01

Background: Previous reviews of tae kwon do (TKD) tournaments have documented injury rates of 25/1000 to 12.7/100 athlete exposures. Most injuries have been reported to be to the head and the neck and are occasionally very serious. Many of these studies involved high level TKD competitions with minimal safety precautions. Recently, safety measures have been implemented in many TKD competitions. Objective: To evaluate retrospectively the incidence of injuries in TKD competitions involving a wide range of participants and featuring extensive safety precautions. Methods: A total of 2498 participants ranged in age from 18 to 66, included both men and women, and ranged in rank from yellow to black belt. Traumas, defined as any event requiring interaction with medical staff, were documented with respect to mechanism, diagnosis, treatment, and follow up recommendations. An injury was defined as a trauma that prevented a contestant from resuming competition on the day that the trauma occurred, according to National Collegiate Athletic Association criteria. Results: The injury rate was 0.4/1000 athlete exposures. This is lower than reported in previous studies of TKD tournaments and in many other sports. Conclusion: TKD tournaments that emphasise limited contact, protective equipment, and medical supervision are relatively safe and compare favourably with other sports. PMID:14514529

Sport is one of the best ways to promote the social integration of people affected by physical disability, because it helps them to increase their self-esteem by facing difficulties and overcoming their disabilities. Nowadays, a large number of sports can be easily played by visually impaired and blind athletes without any special supports, but, there are some disciplines that require the presence of a sighted guide. In this work, the attention will be focused on marathons, during which athletes with visual disorders have to be linked to the sighted guide by means of a non-stretchable elbow tether, with an evident reduction of their performance and autonomy. In this context, this paper presents a fixed electromagnetic infrastructure to equip a standard running racetrack in order to help a blind athlete to safely run without the presence of a sighted guide. The athlete runs inside an invisible hallway, just wearing a light and a comfortable sensor unit. The patented system has been homemade, designed, realized and finally tested by a blind Paralympic marathon champion with encouraging results and interesting suggestions for technical improvements. In this paper (Part I), the transmitting unit, whose main task is to generate the two magnetic fields that delimit the safe hallway, is presented and discussed.

Mountain biking injuries in rural England

Jeys, L; Cribb, G; Toms, A; Hay, S

2001-01-01

Background—Off road mountain biking is now an extremely popular recreation and a potent cause of serious injury. Aim—To establish the morbidity associated with this sport. Methods—Data were collected prospectively over one year on all patients presenting with an injury caused by either recreational or competitive off road mountain biking. Results—Eighty four patients were identified, 70 males and 14 females, with a mean age of 22.5 years (range 8–71). Most accidents occurred during the summer months, most commonly in August. Each patient had an average of 1.6 injuries (n = 133) and these were divided into 15 categories, ranging from minor soft tissue to potentially life threatening. Operative intervention was indicated for 19 patients (23%) and several required multiple procedures. The commonest injuries were clavicle fractures (13%), shoulder injuries (12%), and distal radial fractures (11%). However, of a more sinister nature, one patient had a C2/3 dislocation requiring urgent stabilisation, one required a chest drain for a haemopneumothorax, and another required an emergency and life saving nephrectomy. Conclusion—This sport has recently experienced an explosion in popularity, and, as it carries a significant risk of potentially life threatening injury across all levels of participation, the use of protective equipment to reduce this significant morbidity may be advisable.

Teeing Off With an Entirely New Material

NASA Technical Reports Server (NTRS)

2001-01-01

Liquidmetal(R) alloy is part of an entirely new class of vitrified metals, and is also known as metallic glass, or Vitreloy(R). A vitrified metal is a frozen liquid that fails to crystallize during solidification, unlike common metals such as titanium, steel, and aluminum. The technology takes the non-crystalline structure of glass and combines it with the properties of metal, a combination not found in nature, allowing for a product that offers the strength of a metal with the elasticity of a polymer. This unique technology is more than twice as strong as titanium and has a higher elastic limit. Liquidmetal(R) Golf presents this space-age development in a complete line golf clubs. Clubs made with this technology have a lower vibration response along with a softer, more solid feel. Because less energy is absorbed by the club's head upon impact, more energy is transferred directly to the ball. Vitreloy has potential commercial uses in sporting equipment: tennis rackets, bicycle frames, and baseball bats. The material may find applications in the medical industry for the manufacturing of surgical instruments and prosthetics. The Liquidmetal alloy is projected to replace many high performance materials, such as titanium, in the industries of aerospace, defense, military, automotives, medical instrumentation, and sporting goods

2018-06-01

Many field sports involve equipment that restricts one or both arms from moving while running. Arm swing during running has been examined from a biomechanical and physiologic perspective but not from an injury perspective. Moreover, only bilateral arm swing suppression has been studied with respect to running. The purpose of this study was to determine the influence of running with one arm restrained on lower extremity mechanics associated with running or sport-related injury. Fifteen healthy participants ran at a self-selected speed with typical arm swing, with one arm restrained and with both arms restrained. Lower extremity kinematics and spatiotemporal measures were analysed for all arm swing conditions. Running with one arm restrained resulted in increased frontal plane knee and hip angles, decreased foot strike angle, and decreased centre of mass vertical displacement compared to typical arm swing or bilateral arm swing restriction. Stride length was decreased and step frequency increased when running with one or both arms restrained. Unilateral arm swing restriction induces changes in lower extremity kinematics that are not similar to running with bilateral arm swing restriction or typical arm swing motion. Running with one arm restrained increases frontal plane mechanics associated with risk of knee injury.

Extracurricular school-based sports as a motivating vehicle for sports participation in youth: a cross-sectional study

2014-01-01

Background Extracurricular school-based sports are considered to be an ideal means of reaching children who are not active in community sports. The purposes of this study were to examine the extent to which pupils not engaging in community sports do participate in extracurricular school-based sports, and to assess whether extracurricular school-based sports participants are more physically active and/or more autonomously motivated towards sports in daily life than children who do not participate in extracurricular school-based sports. Methods One thousand forty-nine children (53.7% boys; M age = 11.02 years, SD = 0.02) out of 60 classes from 30 Flemish elementary schools, with an extracurricular school-based sports offer, completed validated questionnaires to assess physical activity (Flemish Physical Activity Questionnaire) and motivation (Behavioral Regulations in Physical Education Questionnaire). Multilevel regression analyses were conducted to examine the data generated from these questionnaires. Results More than three quarters of the children (76%) reported participating in extracurricular school-based sports during the current school year and 73% reported engaging in organized community sports. Almost two third of the children (65%) not participating in community sports stated that they did participate in extracurricular school-based sports. Extracurricular school-based sports participants were significantly more physically active than children not participating in extracurricular school-based sports (β = 157.62, p < 0.001). Significant three-way interactions (sex × extracurricular school-based sports participation × community sports participation) were found for autonomous motivation, with boys engaging in extracurricular school-based sports but not in community sports being significantly more autonomously motivated towards sports than boys not engaging in community or extracurricular school-based sports (β = 0.58, p = 0.003). Such differences were not noted among girls. Conclusions If extracurricular school-based sports are offered at school, the vast majority of elementary school children participate. Although extracurricular school-based sports attract many children already engaging in community sports, they also reach almost two third of the children who do not participate in community sports but who might also be optimally motivated towards sports. As children participating in extracurricular school-based sports are more physically active than children who do not participate, extracurricular school-based sports participation can be considered to contribute to an active lifestyle for these participating children.

2017-01-01

The use of sport psychology strategies during sport injury rehabilitation can lead to several positive outcomes such as improved adherence and self-efficacy. The purpose of this study was to compare the sport psychology related attitudes and behaviours of UK sport injury rehabilitation professionals (SIRPs) who had studied the psychological aspects of sport injury to those who had not. Ninety-four SIRPs (54 physiotherapists and 40 sports therapists with a mean of 9.22 years' experience of working in sport) completed an online survey and were grouped according to their level of previous exposure to sport injury psychology education at an undergraduate/postgraduate level. Analyses were undertaken to establish whether there were any differences in sport psychology related attitude (MANOVA), usage (MANOVA), and referral behaviours (chi square) between the groups. The MANOVA and chi square tests conducted revealed that those who had studied the psychological aspects of sport injury reported using significantly more sport psychology in their practice and making more referrals to sport psychologists. It was concluded that sport injury psychology education appears to be effective in increasing the sport psychology related behaviours (use of sport psychology and referral) of SIRPs and should be integrated into professional training.

Baseball and softball are among the most popular and safest sports in which children and adolescents participate. Nevertheless, traumatic and overuse injuries occur regularly, including occasional catastrophic injury and even death. Safety of the athlete is a constant focus of attention among those responsible for modifying rules. Understanding the stresses placed on the arm, especially while pitching, led to the institution of rules controlling the quantity of pitches thrown in youth baseball and established rest periods between pitching assignments. Similarly, field maintenance and awareness of environmental conditions as well as equipment maintenance and creative prevention strategies are critically important in minimizing the risk of injury. This statement serves as a basis for encouraging safe participation in baseball and softball. This statement has been endorsed by the Canadian Paediatric Society.

Overuse injuries: tendinopathies, stress fractures, compartment syndrome, and shin splints.

PubMed

Wilder, Robert P; Sethi, Shikha

2004-01-01

Approximately 50% of all sports injuries are secondary to overuse and result from repetitive microtrauma that causes local tissue damage. Injuries are most likely with changes in mode, intensity, or duration of training and can accumulate before symptoms appear. Intrinsic factors contributing to injuries are individual bio-mechanical abnormalities such as malalignments, muscle imbalance, inflexibility, weakness, and instability. Contributing extrinsic (avoidable) factors include poor technique, improper equipment, and improper changes in duration or frequency of activity. Injuries are often related to biomechanical abnormalities removed from the specific injury site, requiring evaluation of the entire kinetic chain. This article discusses common overuse injuries of the lower leg, ankle, and foot: tendinopathies, stress fractures, chronic exertional compartment syndrome, and shin splints.

The correspondence of the calculated data to maximal free (independent) particle flight in blank shots was stated. In experiments with cartridges equipped with bullets the distances of free particle flight were significantly lesser (by 53-65%) which may be connected with effect of gunshot projectile on the process of particle distribution. Reversed adapted formulas and calculation variants are presented.

What is the economic burden of sports injuries?

Despite the health benefits of sports activities, sports injury and fear of injury are important barriers to participation in sport. The incidence, prevalence and type of sports injuries vary among men and women as well as age groups. It is usually difficult to examine these different aspects of sports injuries due to insufficient data. This study argues that sport injuries can be considered as an important economic burden in terms of the direct and indirect costs it bears. As a result, strong and effective strategies are needed to prevent sports injuries. Sports medicine has also been attracted increasing attention in recent years, particularly. In this article, the importance of sports injuries and their economic costs as well as the role of sport medicine as a prevention method for sports injuries were discussed.

In 1959, Tannenbaum and Noah reported that sports writers and readers possessed a better understanding of sport terminology than nonreaders. The current investigation extended Tannenbaum and Noah's research using current sport terms. A positive relationship between understanding sport terminology, extent of team identification, strength of sport fandom, and self-proclaimed sport knowledge was hypothesized. Scores of 57 participants confirmed the predicted pattern. Discussion concerned research examining sport terminology.

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.

Sporting activities differ in their ability to promote moderate-to-vigorous physical activity (MVPA). To assess adolescents' engagement in sport under field conditions we used accelerometers to measure their MVPA levels during sport. We pay special attention to differences between team and individual sport and between common sports. Diary data and 7-day accelerometry from 1054 Germans ages 15-17 were combined to measure physical activity. 1373 diaried episodes of more than 40 common sports were identified from 626 participants and grouped into team and individual sport. We modeled the effect of team and individual sport, and described levels of MVPA and episodes of no MVPA for all recorded sports. German boys and girls averaged 43 (SD 21) and 37 (SD 24) minutes MVPA per day. Boys got 2.2 times as much MVPA per minute during team compared to individual sport (p<0.0001) but there was no significant difference for girls. Percent of time spent in MVPA during sport ranged from 6% for weight training to 74% for jogging, with individual sports averaging 10-30% and team sports 30-50%. 11% of sport episodes had no MVPA: half of episodes of cycling, 5% of jogging, and none for tennis or badminton. An episode of individual sport was 17 times more likely to have no MVPA than an episode of team sport (p<0.0001). Under field condition, adolescents were active for only a fraction of diaried sporting time. As measured by accelerometry, individual sport often produced no MVPA. Characteristics of the sport, such as team vs. individual, were more predictive of MVPA than were characteristics of the participant, such as background activity levels.

2004-06-01

Within the context of problem-behaviour theory, this study investigated the intra-relationship between attitudes and behaviours towards exercise, sport involvement, violence in sport-related events, eating fruits, smoking and hashish or ecstasy use in a sample of Greek adolescents. Age and gender patterns are considered. Participants were 5991 Greek school pupils who responded to questionnaires assessing behaviour and attitudes towards health-related behaviours. Positive associations were found between pupils' reports of violence in sport-related events, smoking and hashish or ecstasy use on the one hand, and eating fruits and participation in sport and exercise on the other. In contrast, small positive association was observed between sport involvement and violence in sport-related events. Attitudes towards health risk behaviours were inversely related to attitudes towards health-promoting behaviours, and attitudes were positively related to corresponding behaviours. Sport involvement and regular exercise decreased but smoking and use of hashish or ecstasy increased with age. More males than females participated in organized sport and violent acts in sport-related events. Males' involvement in sport violence increased with age. Sport is a suitable context for the promotion of several health-related behaviours apart from exercise. Nevertheless, the present sport structure excludes most young people and is positively linked with sport violence. A less demanding sport context should be provided for the majority of young people, particularly for females. Sport programmes designed to promote health behaviours should be encouraged. More concentrated actions to combat sport violence are required.

What is a sports injury?

PubMed

Timpka, Toomas; Jacobsson, Jenny; Bickenbach, Jerome; Finch, Caroline F; Ekberg, Joakim; Nordenfelt, Lennart

2014-04-01

Current sports injury reporting systems lack a common conceptual basis. We propose a conceptual foundation as a basis for the recording of health problems associated with participation in sports, based on the notion of impairment used by the World Health Organization. We provide definitions of sports impairment concepts to represent the perspectives of health services, the participants in sports and physical exercise themselves, and sports institutions. For each perspective, the duration of the causative event is used as the norm for separating concepts into those denoting impairment conditions sustained instantly and those developing gradually over time. Regarding sports impairment sustained in isolated events, 'sports injury' denotes the loss of bodily function or structure that is the object of observations in clinical examinations; 'sports trauma' is defined as an immediate sensation of pain, discomfort or loss of functioning that is the object of athlete self-evaluations; and 'sports incapacity' is the sidelining of an athlete because of a health evaluation made by a legitimate sports authority that is the object of time loss observations. Correspondingly, sports impairment caused by excessive bouts of physical exercise is denoted as 'sports disease' (overuse syndrome) when observed by health service professionals during clinical examinations, 'sports illness' when observed by the athlete in self-evaluations, and 'sports sickness' when recorded as time loss from sports participation by a sports body representative. We propose a concerted development effort in this area that takes advantage of concurrent ontology management resources and involves the international sporting community in building terminology systems that have broad relevance.

The following sports ultrasound (SPORTS US) curriculum is a revision of the curriculum developed by the American Medical Society for Sports Medicine (AMSSM) in 2010. Several changes have been made to the curriculum with the primary aim of providing a pathway by which a sports medicine fellow can obtain sufficient SPORTS US training to become proficient in the core competencies of SPORTS US. The core competencies of SPORTS US are outlined in the learning objectives section of this document. The term "SPORTS US" was purposefully chosen rather than "musculoskeletal ultrasound" (MSK US) because it was recognized by the panel that the evolving field of SPORTS US encompasses non-MSK applications of ultrasound such as the FAST examination (focused assessment with sonography for trauma). Although the SPORTS US core competencies in this curriculum are all MSK in nature, they represent the minimum SPORTS US knowledge a sports medicine fellow should acquire during fellowship. However, additional training in more advanced MSK and non-MSK applications of ultrasound can be provided at the fellowship director's discretion. Completion of this SPORTS US curriculum fulfills the American Institute of Ultrasound in Medicine's (AIUM) requirements to perform an MSK US examination and the prerequisites for the American Registry for Diagnostic Medical Sonography's (ARDMS) MSK sonography certification examination.

International medallists' and non-medallists' developmental sport activities - a matched-pairs analysis.

PubMed

Güllich, Arne

2017-12-01

The study examined developmental participation patterns of international top athletes. Pairs of 83 international medallists (including 38 Olympic/World Champions) and 83 non-medallists were matched by sport, age and gender. A questionnaire recorded their volume of organised (coach-led) practice/training in their respective main sport and in other sports through childhood, adolescence and adulthood, and also involvement in non-organised (peer-led) sport activity. Analyses revealed that the medallists started practice/training in their main sport at an older age than non-medallists and accumulated slightly, but significantly less main-sport practice/training through childhood/adolescence. But they participated in more practice/training in other sports, particularly before entering their main sport. The medallists also maintained engagement in other sports over more years and specialised later than the non-medallists. Other sports engaged in were mostly unrelated to an athlete's main sport. The results were robust across different types of sports. The observations are reflected against tenets of the "deliberate practice" and "Developmental Model of Sport Participation" frameworks. Early diversified practice and learning experiences are discussed relative to the expansion of youngsters' potential for future long-term learning. In elite athletes, interaction of sport-specific practice/training with early other-sports participation mostly facilitates long-term attainment of international senior medals.

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 specialized athletes in individual sports also reported higher training volumes and greater rates of overuse injuries than single-sport specialized athletes in team sports.

Massage is a popular treatment choice of athletes, coaches, and sports physical therapists. Despite its purported benefits and frequent use, evidence demonstrating its efficacy is scarce. To identify current literature relating to sports massage and its role in effecting an athlete's psychological readiness, in enhancing sports performance, in recovery from exercise and competition, and in the treatment of sports related musculoskeletal injuries. Electronic databases were used to identify papers relevant to this review. The following keywords were searched: massage, sports injuries, athletic injuries, physical therapy, rehabilitation, delayed onset muscle soreness, sports psychology, sports performance, sports massage, sports recovery, soft tissue mobilization, deep transverse friction massage, pre-event, and post exercise. RESEARCH STUDIES PERTAINING TO THE FOLLOWING GENERAL CATEGORIES WERE IDENTIFIED AND REVIEWED: pre-event (physiological and psychological variables), sports performance, recovery, and rehabilitation. Despite the fact clinical research has been performed, a poor appreciation exists for the appropriate clinical use of sports massage. Additional studies examining the physiological and psychological effects of sports massage are necessary in order to assist the sports physical therapist in developing and implementing clinically significant evidence based programs or treatments.

The evolution of sports medicine in Singapore.

Tan, Benedict

2013-10-01

Sports medicine is a relatively new subspecialty in Singapore. This commentary chronicles its evolution in Singapore from 1969, through various milestones, to the present day. The first sports medicine clinic in Singapore was established in 1971 at Farrer Park. Notable institutions that followed include the Sports Medicine and Research Centre (1973), Soldier Performance Centre, Changi Sports Medicine Centre (2003), Singapore Sports Medicine Centre (2006), and other multidisciplinary centres of restructured hospitals. Formal groundwork to establish sports medicine as a subspecialty began in 2005, with its first trainee commencing traineeship at the Changi Sports Medicine Centre in 2007, and culminated in the subspecialty register at the beginning of 2011. Also captured in this discussion are the broader scopes of sports medicine, including military sports medicine, the sports sciences, exercise medicine, and event medical coverage.

Many children are not physically active enough for a health benefit. One avenue of physical activity is modified sport programs, designed as an introduction to sport for young children. This longitudinal study identified trends in participation among children aged 4-12 years. Outcomes included continuation in the modified sports program, withdrawal from the program or transition to club sport competition. De-identified data on participant membership registrations in three popular sports in the Australian state of Victoria were obtained from each sport's state governing body over a 4-year period (2009-2012 for Sport A and 2010-2013 for Sports B and C). From the membership registrations, those who were enrolled in a modified sports program in the first year were tracked over the subsequent three years and classified as one of: transition (member transitioned from a modified sport program to a club competition); continue (member continued participation in a modified sport program; or withdraw (member discontinued a modified program and did not transition to club competition). Many modified sports participants were very young, especially males aged 4-6 years. More children withdrew from their modified sport program rather than transitioning. There were age differences between when boys and girls started, withdrew and transitioned from the modified sports programs. If we can retain children in sport it is likely to be beneficial for their health. This study highlights considerations for the development and implementation of sport policies and programming to ensure lifelong participation is encouraged for both males and females.

Sports drink consumption and diet of children involved in organized sport

PubMed Central

2013-01-01

Background Organized sport provides one option for children to be physically active. However, there is a paucity of information about the relationship between children’s participation in organized sport and their diet, and specifically their sports drink consumption. Therefore, the relationship between sports participation in children and the consumption of sports drinks, sugar-sweetened beverages (SSBs) and other components of diet was examined. Methods A cross-sectional descriptive study was conducted using baseline data from the Action Schools! BC Dissemination study cohort (n = 1421; 9.90 (0.58) y; 736 girls, 685 boys). The differences between the dietary behaviours of children participating in organized sport (sport) versus those that did not participate (non-sport) was examined. A modified Physical Activity Questionnaire for Older Children (PAQ-C) was used to measure physical activity levels and participation in organized sport. A Food Frequency Questionnaire (FFQ) and 24-hour dietary recall were used to assess eating behaviour and macronutrient intake (including protein, fat, and carbohydrate as well as sugar, fibre and total calories). Fruit, vegetable and beverage quantities were hand-tallied from the dietary recall. Fruit, vegetable and beverage frequency was assessed using the FFQ. Analysis of covariance (ANCOVA) was used to analyse differences between groups and a chi-square test of association was use to determine if participation in sport was significantly associated with the proportion of children consuming sports drinks and SSBs, and with gender. Results Children involved in sport had a lower body mass index (BMI) and were more physically active than children in the non-sport group (p < 0.01). Only a small number (n = 20/1421) of children consumed sports drinks and no difference in consumption of sports drink between sport and non-sport participants (p > .05) was observed. However, children involved in organized sport consumed more total calories, fat, fibre, fruit, vegetables and non-flavoured milk (p < 0.01) than non-sport children. Conclusions Children involved in organized sport were more physically active, consumed a healthier diet than non-participants and on average had lower BMI’s despite consuming more calories. As consumption of sports drinks among this age group was low, this may be an ideal time to begin educating children and their parents about the appropriate consumption of sports drinks and the perils of consuming too many SSBs, specifically.

The main aim of this study was to examine the differences in motivation to participate in sport activities among sports students from three different countries. On a sample of 390 sports students from Slovenia, Croatia and Germany we studied what motivates an interest in being sports active. The sample was stratified across the choice to attend table tennis lessons at all three institutions and all students have completed the Participation Motivation Questionnaire (PMQ). The results revealed that the latent structure of the types of sports students’ motives consisted of six factors (sport action with friend, popularity, fitness & health, social status, sports events, relaxation through sports). We also found significant sex differences in motivation to participate in sport activities for all sports students from the three different countries. We did not find relevant age-based differences among the students, and this is the only initial hypothesis that we can reject. Key points The potential implications of the result can be in better understanding the relationship between different motivational orientations - in particular, extrinsic motivation - and sport motivation among school-aged individuals. In the context of Self Determination Theory, students can be encouraged in developing more autonomous orientations for sport activity, rather than controlled and impersonal, especially in certain countries. Significant factors of differences have been found in motivation to participate in sport activities among sports students from three different countries and also some significant sex differences have been found in motivation to participate in sport activities for all sports students.

The aging phenomenon results in body organ system debilitating, which causes the balance weakening and makes a fall, fracture rate, and further medical cost to increase. The lack of exercise has been linked to increasing the incidence of hypertension, coronary artery disease, osteoporosis, degenerative arthritis, and diabetes. Chronic disease affects patients both in psychological and physiological functions which limit their daily activity. In the past, many researches pointed out that these patients can improve their balance sensation by exercise. Because of the above reasons, this research implementation forms a wireless platform of information connection system and medical data analysis. First of all, the target population in the society focuses on those elderly with the common chronic diseases, such as skeletal muscle diseases and degenerative arthritis. Using the hydraulic resist practicing equipment as the mainstay intervention can help examinee collecting the practice value and further analysis. The platform of information accords not only the data prior and after the exercise but also graphic data presentation and analysis from the medical staff members providing services in the society. It can also provide the medical unit to create data mold and a body health counselor when services in the society.

Construction of an isokinetic eccentric cycle ergometer for research and training.

2013-08-01

Eccentric cycling serves a useful exercise modality in clinical, research, and sport training settings. However, several constraints can make it difficult to use commercially available eccentric cycle ergometers. In this technical note, we describe the process by which we built an isokinetic eccentric cycle ergometer using exercise equipment modified with commonly available industrial parts. Specifically, we started with a used recumbent cycle ergometer and removed all the original parts leaving only the frame and seat. A 2.2 kW electric motor was attached to a transmission system that was then joined with the ergometer. The motor was controlled using a variable frequency drive, which allowed for control of a wide range of pedaling rates. The ergometer was also equipped with a power measurement device that quantified work, power, and pedaling rate and provided feedback to the individual performing the exercise. With these parts along with some custom fabrication, we were able to construct an isokinetic eccentric cycle ergometer suitable for research and training. This paper offers a guide for those individuals who plan to use eccentric cycle ergometry as an exercise modality and wish to construct their own ergometer.

Sports specialization in young athletes: evidence-based recommendations.

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 purpose of this study was to investigate if children perceived certain sports to be masculine, feminine, or neutral. Students attending a University Laboratory school (grades K-12) were asked to fill out a survey about sports during a class period, Children in grades K-6 were given a sport (such as baseball) and asked if a boy named David would play it, if a girl named Jane would play it, or if both David and Jane would play the sport. Students in grades 7-12 were asked to name their favorite athlete or team and sport and indicate what sports they felt was best for a girl and a boy. Then they were given a list of sports and asked to indicate, using a 5-point Likert-type scale, whether they believed the sport was masculine, neutral, or feminine. Results from loglinear analyses indicated that students sex-typed certain sports, such as aerobics and football. Additionally, although some responses from students in grades 7-12 indicated that individuals should be able to play any sport they wanted, there were many gendered rsponses in terms of what sport(s) girls and boys should participate in. The results are discussed with reference to Metheny's categories of permissible sports for girls and in the framework of the gender typing of sport.

The Role of Massage in Sports Performance and Rehabilitation: Current Evidence and Future Direction

PubMed Central

2008-01-01

Background Massage is a popular treatment choice of athletes, coaches, and sports physical therapists. Despite its purported benefits and frequent use, evidence demonstrating its efficacy is scarce. Purpose To identify current literature relating to sports massage and its role in effecting an athlete's psychological readiness, in enhancing sports performance, in recovery from exercise and competition, and in the treatment of sports related musculoskeletal injuries. Methods Electronic databases were used to identify papers relevant to this review. The following keywords were searched: massage, sports injuries, athletic injuries, physical therapy, rehabilitation, delayed onset muscle soreness, sports psychology, sports performance, sports massage, sports recovery, soft tissue mobilization, deep transverse friction massage, pre-event, and post exercise. Results Research studies pertaining to the following general categories were identified and reviewed: pre-event (physiological and psychological variables), sports performance, recovery, and rehabilitation. Discussion Despite the fact clinical research has been performed, a poor appreciation exists for the appropriate clinical use of sports massage. Conclusion Additional studies examining the physiological and psychological effects of sports massage are necessary in order to assist the sports physical therapist in developing and implementing clinically significant evidence based programs or treatments.

School sports and identity formation: socialisation or selection?

PubMed

Pot, Niek; Schenk, Niels; van Hilvoorde, Ivo

2014-01-01

It seems common knowledge that school sport participation leads to all kinds of social, educational and health outcomes. However, it may also be that students with a certain predisposition, sometimes referred to as sporting habitus, are more inclined to participate in school sports and that the 'outcomes' were already present before participation. Several studies indicated that identity formation mediates between sport participation and the outcomes described. Therefore, a longitudinal survey study was used to investigate whether participation in an elementary school sport competition brought about changes in the formation of sport identity and student identity of students. The results of the study showed that participation in the competition was not related to changes in the sport identity and student identity of the children. In contrast to commonplace assumptions about the socialising effects of school sport participation, the results indicate that participating in this school sport competition did not influence the student identity and sport identity of children. It may be that a selected, predisposed group of children with a strong sport identity participates in school sports, although future research is necessary to test this hypothesis.

We aimed to increase understanding of the link between sport specialization during childhood and adolescent physical activity (PA). The objectives were as follows: (1) describe the natural course of sport participation over 5 years among children who are early sport samplers or early sport specializers and (2) determine if a sport participation profile in childhood predicts the sport profile in adolescence. Participants ( n = 756, ages 10-11 years at study inception) reported their participation in organized and unorganized PA during in-class questionnaires administered every 4 months over 5 years. They were categorized as early sport samplers, early sport specializers, or nonparticipants in year 1 and as recreational sport participants, performance sport participants, or nonparticipants in years 2 to 5. The likelihood that a childhood sport profile would predict the adolescent profile was computed as relative risks. Polynomial logistic regression was used to identify predictors of an adolescent sport profile. Compared with early sport specialization and nonparticipation, early sport sampling in childhood was associated with a higher likelihood of recreational participation (relative risk, 95% confidence interval: 1.55, 1.18-2.03) and a lower likelihood of nonparticipation (0.69, 0.51-0.93) in adolescence. Early sport specialization was associated with a higher likelihood of performance participation (1.65, 1.19-2.28) but not of nonparticipation (1.01, 0.70-1.47) in adolescence. Nonparticipation in childhood was associated with nearly doubling the likelihood of nonparticipation in adolescence (1.88, 1.36-2.62). Sport sampling should be promoted in childhood because it may be linked to higher PA levels during adolescence. Copyright © 2017 by the American Academy of Pediatrics.

Physical activity is considered as a major component of a healthy lifestyle. However, few studies have examined the relationships between the spatial accessibility to sport facilities and sport practice with a sufficient degree of specificity. The aim of this study was to investigate the associations between the spatial accessibility to specific types of sports facilities and the practice of the corresponding sports after carefully controlling for various individual socio-demographic characteristics and neighborhood socioeconomic variables. Data from the RECORD Study involving 7290 participants recruited in 2007-2008, aged 30-79 years, and residing in the Paris metropolitan area were analyzed. Four categories of sports were studied: team sports, racket sports, swimming and related activities, and fitness. Spatial accessibility to sport facilities was measured with two complementary approaches that both take into account the street network (distance to the nearest facility and count of facilities around the dwelling). Associations between the spatial accessibility to sport facilities and the practice of the corresponding sports were assessed using multilevel logistic regression after adjusting for individual and contextual characteristics. High individual education and high household income were associated with the practice of racket sports, swimming or related activities, and fitness over the previous 7 days. The spatial accessibility to swimming pools was associated with swimming and related sports, even after adjustment for individual/contextual factors. The spatial accessibility to facilities was not related to the practice of other sports. High neighborhood income was associated with the practice of a racket sport and fitness. Accessibility is a multi-dimensional concept that integrates educational, financial, and geographical aspects. Our work supports the evidence that strategies to increase participation in sport activities should improve the spatial and financial access to specific facilities, but also address educational disparities in sport practice.

A worldwide consensus for timing and criteria for return to sport after anterior cruciate ligament (ACL) reconstruction is lacking. The aim of the study was to survey among the Italian Society of Knee, Arthroscopy, Sport, Cartilage and Orthopaedic Technologies (SIGASCOT) members in order to evaluate their approaches to the return to sport after ACL reconstruction regarding timing and criteria. A web survey among the SIGASCOT members was performed, including 14 questions regarding technical and graft preferences, timing for return to training and competitive activity for contact and non-contact sports and criteria to allow return to sport. Totally, 123 members completed the questionnaire. Return to training sports was allowed within 6 month by 87 % for non-contact sports and by 53 % for contact sports. Return to competitive activity was allowed within 6 months by 48 % for non-contact sports and by 13 % for contact sports. Full ROM (77 %), Lachman test (65 %) and Pivot-Shift test (65 %) were the most used criteria to allow return to sport. The 90 % used at least one clinical score. The SIGASCOT members showed various approaches in the return to sport after ACL reconstruction, with differences between return to training or competitive activity, and between contact and non-contact sports. Six months was generally considered adequate by most of the members for the most demanding activities. The most used criteria to allow return to sport were manual testing. A clear definition of sport activities and more objective criteria for the return to sport are needed. Level V, expert opinion.

Extracurricular school sports programs can provide adolescents, including those who are economically disadvantaged, with opportunities to engage in physical activity. Although current models favor more exclusionary interscholastic sports, a better understanding is needed of the potential effects of providing alternative school sports options, such as more inclusive intramural sports. The purpose of this study was to simulate the potential effect of implementing intramural sports programs in North Carolina middle schools on both the rates of sports participation and on energy expenditure related to physical activity levels. Simulations were conducted by using a school-level data set developed by integrating data from multiple sources. Baseline rates of sports participation were extrapolated from individual-level data that were based on school-level characteristics. A regression model was estimated by using the simulated baseline school-level sample. Participation rates and related energy expenditure for schools were calculated on the basis of 2 policy change scenarios. Currently, 37.2% of school sports participants are economically disadvantaged. Simulations suggested that policy changes to implement intramural sports along with interscholastic sports could result in more than 43,000 new sports participants statewide, of which 64.5% would be economically disadvantaged students. This estimate represents a 36.75% increase in economically disadvantaged participants. Adding intramural sports to existing interscholastic sports programs at all middle schools in North Carolina could have an annual effect of an additional 819,892.65 kilogram calories expended statewide. Implementing intramural sports may provide economically disadvantaged students more access to sports, thus reducing disparities in access to school sports while increasing overall physical activity levels among all children.

This study compared use of imagery in elite male and female athletes in open and closed and individual or team sports. A total of 151 elite Turkish athletes ages 15 to 29 years old (males' M age=20.7 yr., SD=3.3; females' M age=20.0 yr., SD=3.5) from open-team sports (n=66), open-individual sports (n=26), and closed-individual sports (n=59) completed the sport imagery questionnaire. A significant multivariate effect of sport type was found. Univariate analyses indicated that male and female athletes in team open-skill sports and individual closed-skill sports used more motivational general-mastery imagery than did athletes in individual open-skill sports.

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.

Position data of players and athletes are widely used in sports performance analysis for measuring the amounts of physical activities as well as for tactical assessments in game sports. However, positioning sensing systems are applied in sports as tools to gain objective information of sports behavior rather than as components of intelligent spaces (IS). The paper outlines the idea of IS for the sports context with special focus to game sports and how intelligent sports feedback systems can benefit from IS. Henceforth, the most common location sensing techniques used in sports and their practical application are reviewed, as location is among the most important enabling techniques for IS. Furthermore, the article exemplifies the idea of IS in sports on two applications. PMID:22163725

Interest in sports and belief in sports superstitions.

51 nonathletes, students (45 women) at a medium-sized southern university, were administered a survey containing three scales: an Interest in Sports Scale, a Belief in Sports Superstitions Scale, and Tobacyk and Milford's Paranormal Belief Scale (1983). Scores on the Interest in Sports Scale were significantly correlated with scores on the Belief in Sports Superstitions Scale, which measured adherence specifically to sports superstitions, but not with scores on the Paranormal Belief Scale, which measured a wide variety of irrational beliefs. Thus, participants with high interest in sports showed a tendency to subscribe to the type of irrational belief associated specifically with sports. Scores on the Belief in Sports Superstitions Scale were positively correlated with scores on the Paranormal Belief Scale.

Tobacco companies have historically associated their products with sports through event sponsorship and sports-themed advertising campaigns. Such linkages serve to enhance brand image by connecting cigarette brands to ideals associated with sports such as strength, individual accomplishment, and a healthy body. Public health policy progress has created restrictions for tobacco sponsorship and restricted traditional advertising avenues for tobacco products. Nonetheless, the pack itself remains as a mechanism by which to link cigarettes to sports and sporting prowess. Thus, we analyze depictions of sport and references to sports terminology on cigarette packs. To describe the sports-related marketing appeals on cigarette packages purchased in 14 low and middle income countries. In 2013, we collected and coded cigarette packs from 14 low and middle income countries and we returned to four of these countries for further data collection in 2015. Packs from both years were assessed for sports-related appeals (text and imagery) and sports-related brand names to identify sports appeals on cigarette packs. The analysis yielded 36 brands with distinct depictions of sport or sporting terminology on the pack. Text-based appeals were found on 24 of the 36 distinct "sports appeal" packs (e.g., "Polo," "Olympic," "Win," "iScore"). Sporting imagery was present on 22 packs (e.g., soccer ball, race car, wrestling match, trophy). The pack is a powerful medium through which tobacco companies continue to associate their products with idealized concepts associated with sports. These are potentially problematic associations that could be restricted through plain and standardized packaging policy initiatives.

2014-10-01

Participation in fantasy sports increases annually. Wagering on fantasy sports is a form of gambling and researchers have found that fantasy sports participants are more likely to engage in other forms of sports betting than non-fantasy players; however, no published studies have examined whether there is a relationship between fantasy sports participation and gambling-related problems. Our study examined whether fantasy sports participation is associated with gambling-related problems among college students. We assessed fantasy sports participation and endorsement of DSM-5 gambling disorder (GD) criteria among a large convenience sample (N=1556) of college students via an online health survey. We found that 11.5% of respondents participated in fantasy sports in the past year, the majority of which were males. Logistic regression analyses indicated that males who play fantasy sports for money and females who play fantasy sports (for money or not) were more likely to experience gambling-related problems.

The aim of this study was to investigate if baseline motor competence, weight status and sports participation in early childhood predict sports participation two years later. longitudinal study. In 2010, motor competence (object control and locomotor skills), weight status and sports participation were assessed in 292 children between three and five years-of-age. In 2012, sports participation was re-evaluated in 206 of the original 292 children. Logistic regression was implemented to examine if initial sports participation, motor competence and weight status would predict sports participation two years later. In the final model, sports participation in 2010 (OR=9.68, CI: 3.46 to 27.13) and locomotor skills (OR=1.21, CI: 1.01 to 1.46) significantly predicted sports participation after two years. These results suggest that initial sports participation and more advanced locomotor skills in preschool years may be important to promote continued participation in sports across childhood.

Most high-grade renal injuries (American Association for Surgery of Trauma (AAST) grades III-V) result from motor vehicle collisions associated with numerous concomitant injuries. Sports-related blunt renal injury tends to have a different mechanism, a solitary blow to the flank. We hypothesized that high-grade renal injury is often isolated in sports-related renal trauma. We identified patients with AAST grades III-V blunt renal injuries from four level 1 trauma centres across the United States between 1/2005 and 1/2014. Patients were divided into "Sport" or "Non-sport" related groups. Outcomes included rates of hypotension (systolic blood pressure <90mm Hg), tachycardia (>110bpm), concomitant abdominal injury, and procedural/surgical intervention between sports and non-sports related injury. 320 patients met study criteria. 18% (59) were sports-related injuries with the most common mechanisms being skiing, snowboarding and contact sports (25%, 25%, and 24%, respectively). Median age was 24 years for sports and 30 years for non-sports related renal injuries (p=0.049). Males were more commonly involved in sports related injuries (85% vs. 72%, p=0.011). Median injury severity score was lower for sports related injuries (10 vs. 27, p<0.001). There was no difference in renal abbreviated injury scale scores. Sports related trauma was more likely to be isolated without other significant injury (69% vs. 39% (p<0.001)). Haemodynamic instability was present in 40% and 51% of sports and non-sports renal injuries (p=0.30). Sports injuries had lower transfusion (7% vs. 47%, p<0.001) and lower mortality rates (0% vs. 6%, p=0.004). There was no difference in renal-specific procedural interventions between the two groups (17% sports vs. 18% non-sports, p=0.95). High-grade sports-related blunt renal trauma is more likely to occur in isolation without other abdominal or thoracic injuries and clinicians must have a high suspicion of renal injury with significant blows to the flank during sports activities.

Physical activity improves health outcomes in colorectal cancer (CRC) survivors, but participation rates are low. One understudied strategy for increasing physical activity in CRC survivors may be sport participation. Here, we report the sport participation rate, sport preferences, and correlates of sport participation among CRC survivors. A provincial, population-based mailed survey of CRC survivors in Alberta, Canada was performed and included measures of sport participation, sport preferences, sport benefits and barriers, and medical and demographic variables. A total of 600 CRC survivors completed the survey (34 % response rate). Almost a quarter (23.0 %) of CRC survivors reported participating in a sport in the past month, with the most common sport being golf (58.7 %). In multivariate regression analysis, 33.0 % (p = 0.001) of the variance in sport participation was explained by being male (β = 0.12; p = 0.006), in better general health (β = 0.12; p = 0.006), and ≥ 5 years post-diagnosis (β = 0.09; p = 0.031). The most common barriers to sport participation were time, age/agility, and no interest/dislike of sports. The most common anticipated benefits of sport participation were improved physical fitness, meeting people, and improved health. Over half (57.2 %) of CRC survivors were possibly interested in learning about sport participation opportunities. Promotion of sport participation may be a potentially fruitful strategy for increasing physical activity in CRC survivors.

We studied cortical morphology in relation to sports participation and type of sport using a large sample of healthy children (n = 911). Sports participation data was collected through a parent-reported questionnaire. Magnetic resonance scans were acquired, and different morphological brain features were quantified. Global volumetric measures were not associated with sports participation. We observed thicker cortex in motor and premotor areas associated with sports participation. In boys, team sports participation, relative to individual sports, was related to thinner cortex in prefrontal brain areas involved in the regulation of behaviors. This study showed a relationship between sports participation and brain maturation.

This descriptive study evaluated behavioral and social science research on sport for 1993 through 2008, examined the characteristics of sport research, and identified mainstream issues appearing during these 16 years. Based on the Social Science Citation Index (SSCI) database from 1993 to 2008, 7,655 articles referring to sport or sports were available. The publication analyses showed that 13 core journals published the most articles in the behavioral sciences of sport. By analyzing all titles, author keywords, and KeyWords Plus, the results showed that physical education, athlete performance, and sports participation were the mainstream issues of sport research in the 16-year study period. The words adolescent, youth, and children frequently appeared, indicating that the emphasis of sport research focused on these participant groups. This bibliometric study reviewed global sports research in SSCI, and described certain patterns or trends in prior research on sport.

The influence of socio-demographic indicators economic determinants and social recognition on sport participation in Germany.

PubMed

Hallmann, Kirstin; Breuer, Christoph

2014-01-01

This article analyses sport participation using a demographic-economic model which was extended by the construct 'social recognition'. Social recognition was integrated into the model on the understanding that it is the purpose of each individual to maximise his or her utility. A computer-assisted telephone interview survey was conducted in the city of Rheinberg, Germany, producing an overall sample of n=1934. Regression analyses were performed to estimate the impact of socio-demographic, economic determinants, and social recognition on sport participation. The results suggest that various socio-economic factors and social recognition are important determinants of sport participation on the one hand, and on sport frequency on the other. Social recognition plays a significant yet different role for both sport participation and sport frequency. While friends' involvement with sport influences one's sport participation, parents' involvement with sport influences one's sport frequency.

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 of every 5 athletes were playing their preinjury level of sport at 2 years after surgery. When the results of the current study were combined with the results of athletes who had returned to sport at 1 year, the overall rate of return to the preinjury level sport at 2 years was 60%. Demographics, physical function, and psychological factors were related to playing the preinjury level sport at 2 years after surgery, supporting the notion that returning to sport after surgery is multifactorial. © 2015 The Author(s).

Sports Specialization in Young Athletes

PubMed Central

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.

Objectives This study sought to determine if sport specialization increases the risk of anterior knee pain in adolescent female athletes. Design Retrospective cohort epidemiology study. Methods Female basketball, soccer and volleyball players (N=546) were recruited from a single county public school district in Kentucky consisting of five middle schools and four high schools. A total of 357 multi-sport, and 189 single sport (66 basketball, 57 soccer and 66 volleyball) athlete subjects were included due to their diagnosis of patellofemoral pain on physical exam. Testing consisted of completion of a standardized history and physician-administered physical examination to determine the presence of patellofemoral pain (PFP). This study compared self-reported multi-sport athletes with sport specialized athletes participating in only one sport. The sports participation data was normalized by sport season with each sport accounting for one season of exposure. Incidence rate ratios (IRR) and 95% confidence intervals (CI) were calculated and used to determine significant differences between athletes who specialized in sport in early youth and multi-sport athletes. Results Specialization in a single sport increased the relative risk of PFP incidence by 1.5 fold (95% CI 1.0 to 2.2; p=0.038) for cumulative PFP diagnoses. Specific diagnoses such as Sinding Larsen Johansson/patellar tendinopathy (95% CI 1.5 to 10.1; p=0.005) and Osgood Schlatter Disease (95% CI 1.5 to 10.1; p=0.005) demonstrated a four-fold greater relative risk in single sport compared to multiple sport athletes. Other specific PFP diagnoses such as Fat Pad, Plica, Trauma, Pes Anserine Bursitis and IT Band Tendonitis incidence were not different between single sport and multiple sport participants (p>0.05). Conclusion Early sport specialization in female adolescents is associated with increased risk of anterior knee pain disorders including PFP, Osgood Schlatter, Sinding Larsen-Johansson compared to multi-sport athletes.

Sport Specialization, Part I: Does Early Sports Specialization Increase Negative Outcomes and Reduce the Opportunity for Success in Young Athletes?

PubMed

Myer, Gregory D; Jayanthi, Neeru; Difiori, John P; Faigenbaum, Avery D; Kiefer, Adam W; Logerstedt, David; Micheli, Lyle J

2015-01-01

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.

Circadian variation in sports performance.

PubMed

Atkinson, G; Reilly, T

1996-04-01

Chronobiology is the science concerned with investigations of time-dependent changes in physiological variables. Circadian rhythms refer to variations that recur every 24 hours. Many physiological circadian rhythms at rest are endogenously controlled, and persist when an individual is isolated from environmental fluctuations. Unlike physiological variables, human performance cannot be monitored continuously in order to describe circadian rhythmicity. Experimental studies of the effect of circadian rhythms on performance need to be carefully designed in order to control for serial fatigue effects and to minimise disturbances in sleep. The detection of rhythmicity in performance variables is also highly influenced by the degree of test-retest repeatability of the measuring equipment. The majority of components of sports performance, e.g. flexibility, muscle strength, short term high power output, vary with time of day in a sinusoidal manner and peak in the early evening close to the daily maximum in body temperature. Psychological tests of short term memory, heart rate-based tests of physical fitness, and prolonged submaximal exercise performance carried out in hot conditions show peak times in the morning. Heart rate-based tests of work capacity appear to peak in the morning because the heart rate responses to exercise are minimal at this time of day. Post-lunch declines are evident with performance variables such as muscle strength, especially if measured frequently enough and sequentially within a 24-hour period to cause fatigue in individuals. More research work is needed to ascertain whether performance in tasks demanding fine motor control varies with time of day. Metabolic and respiratory rhythms are flattened when exercise becomes strenuous whilst the body temperature rhythm persists during maximal exercise. Higher work-rates are selected spontaneously in the early evening. At present, it is not known whether time of day influences the responses of a set training regimen (one in which the training stimulus does not vary with time of day) for endurance, strength, or the learning of motor skills. The normal circadian rhythms can be desynchronised following a flight across several time zones or a transfer to nocturnal work shifts. Although athletes show all the symptoms of 'jet lag' (increased fatigue, disturbed sleep and circadian rhythms), more research work is needed to identify the effects of transmeridian travel on the actual performances of elite sports competitors. Such investigations would need to be chronobiological, i.e. monitor performance at several times on several post-flight days, and take into account direction of travel, time of day of competition and the various performance components involved in a particular sport. Shiftwork interferes with participation in competitive sport, although there may be greater opportunities for shiftworkers to train in the hours of daylight for individual sports such as cycling and swimming. Studies should be conducted to ascertain whether shiftwork-mediated rhythm disturbances affect sports performance. Individual differences in performance rhythms are small but significant. Circadian rhythms are larger in amplitude in physically fit individuals than sedentary individuals. Athletes over 50 years of age tend to be higher in 'morningness', habitually scheduling relatively more training in the morning and selecting relatively higher work-rates during exercise compared with young athletes. These differences should be recognised by practitioners concerned with organising the habitual regimens of athletes.

Adolescents involved in weight-related and power team sports have better eating patterns and nutrient intakes than non-sport-involved adolescents.

To examine eating habits and energy and nutrient intake among adolescents participating in weight-related and power team sports and non-sport-involved adolescents. Data were drawn from Project EAT (Eating Among Teens), which was conducted with 4,746 adolescents from 31 middle and high schools in the Minneapolis/St Paul metropolitan area. Urban secondary schools. Adolescents reporting participation in a weight-related sport, a power team sport, or no consistent participation in a sport. Meal and snack frequency, mean energy and nutrient intake, and mean physical activity. Analyses were conducted by sex across the three groups. General linear models were used to compare mean energy and nutrient intake, composite nutrient adequacy, and mean physical activity across the three groups. Percentages of youth meeting nutrient recommendations were compared across the three groups using chi(2) tests. For both males and females, youth involved in weight-related sports ate breakfast more frequently than non-sport-involved peers (females: 3.6 and 3.2 times per week, respectively, P<0.01; males: 4.7 and 3.7 times per week, respectively, P<0.01). Weight-related and power team sport-involved youth also had higher mean protein, calcium, iron, and zinc intakes than non-sport-involved peers. However, adolescent females had low calcium intake, regardless of sports involvement (weight-related sports 1,091 mg/day, power team sports 1,070 mg/day, and non-sport-involved 1,028 mg/day, P<0.05). Sport-involved adolescents have better eating habits and nutrient intake than their non-sport-involved peers. However, they are still in need of nutrition interventions, particularly around calcium intake.

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.

Violence in youth sports: hazing, brawling and foul play.

PubMed

Fields, S K; Collins, C L; Comstock, R D

2010-01-01

By separating hazing, brawling, and foul play and failing to recognise that their connection to sport binds them together into a cohesive subset of sport injury and youth violence, past research has failed to show how sports-related violence is a broad example of interpersonal violence. The acceptance of violence within the sporting culture may, in part, explain why sports-related violence has not yet been widely recognised as a public health concern. This review shows that sports-related violence, including hazing, brawling and foul play, occurs among youth athletes of all ages and in a variety of different sports. The few studies to address this issue have all acknowledged the dangers of sports-related violence; however, no incident tracking method has been developed. Future research must provide accurate national estimates of the incidence of sports-related violence among youth, identify associated risk factors, evaluate preventive interventions and identify effective methods of distributing and implementing evidence-based interventions. Monitoring the magnitude and distribution of the burden of sports-related violence and building the scientific infrastructure necessary to support the development and widespread application of effective sports-related prevention interventions are essential first steps toward a reduction in the incidence of sports-related violence.

2018-01-01

Youth sport participation plays an important role in promoting physical activity among children and may be a possible venue for the prevention of pediatric obesity. To design effective physical activity interventions, it is imperative to understand how different aspects of sport participation influence physical activity (PA). The purpose of this article is to present a comprehensive review of the impact of youth sport participation on children's PA and obesity status. A total of 44 studies published up to January 2014 concerning youth sport participation, PA, and obesity status were identified. Inclusion criteria were studies comparing PA levels of sport participants to nonparticipants or those comparing PA levels in different sport types and settings. Studies with the outcome variables of obesity status (e.g., body mass index, fat percentage, waist circumference) were also included. Participation in youth sport was positively associated with children's PA levels, and youth participating in sports were more likely to persist in their PA. However, the relationship between youth sport participation and obesity status was inconclusive. Educators and sports professionals should find ways to involve children in various sports settings and policies and help obese children engage more in sports.

Investigation and Analysis on Sports Consumption of Urban Residents of Henan Province

NASA Astrophysics Data System (ADS)

Ying, Wu Lan

With economic development, urban residents' in levels rises gradually and their daily consumption structure tends to be demands of development and enjoyment. Sport consumption, as a social and cultural consumption, with a high level of enjoyment and development of consumer properties, has been gradually recognized by the general population and an important reference for the measure of quality of residents' life. In this paper, questionnaire survey, literature, expert interviews and mathematical statistics methods are used to analyze the awareness, motivation, level of consumption, survey structure and constraints of sports consumption of urban residents of Henan Province. The results are: the proportion of sports participants of urban residents' of Henan Province is small, there is a large space for sports consumption development; sports consumer awareness is relatively backward, sports consumption values are gradually formed; the overall level of sports consumption is low and the consumption structure is single. Therefore, the advocacy of sports consumption should be strengthened, attention should be paid to physical infrastructure, strengthening the sports industry structure optimization, put emphasis on the introduction and training of sports talents, target to develop sports tourism and minority sports resources, and create a good environment of csports consumption.

Although sport participation is encouraged throughout the lifespan, little research has been conducted on the role of sport in development later in life. This qualitative study explored adults' experiences of development within the context of Masters sport. We interviewed 14 adults (nine men and five women) aged 46-61 years involved in Masters sport. Data was interpreted drawing upon frameworks from youth sport (i.e., Personal Assets Framework for Sport; Côté, J., Bruner, M., Strachan, L., Erickson, K., & Fraser-Thomas, J. (2010). Athletes' development and coaching. In J. Lyle & C. Cushion (Eds.), Sport coaching: Professionalism and practice (pp. 63-83). Oxford, UK: Elsevier, Côté, J., Turnnidge, J., & Evans, M. B. (2014).

International Journal of Sports Science & Coaching, 7(3), 601-614. doi:10.1260/1747-9541.7.3.601), combined with past research on mid-life and older athletes. Six key themes emerged as contributing to adults' personal development through sport: competence and confidence, character, commitment, connection, cognition, and challenge. Masters sport contexts appeared to facilitate changes in assets (i.e., 6Cs) similar to those within youth sport, but assets often held different meanings within the context of later life. Applying frameworks from youth sport and developmental psychology to Masters sport contexts appears useful. The current findings support the modification of existing models and highlight their potential in identifying lifelong developmental outcomes of sport participation.

Meeting the global demand of sports safety: the intersection of science and policy in sports safety.

Sports and physical activity are transforming, and being transformed by, the societies in which they are practised. From the perspectives of both competitive and non-competitive sports, the complexity of their integration into today's society has led to neither sports federations nor governments being able to manage the safety problem alone. In other words, these agencies, whilst promoting sport and physical activity, deliver policy and practices in an uncoordinated way that largely ignores the need for a concurrent overall policy for sports safety. This article reviews and analyses the possibility of developing an overall sports safety policy from a global viewpoint. Firstly, we describe the role of sports in today's societies and the context within which much sport is delivered. We then discuss global issues related to injury prevention and safety in sports, with practical relevance to this important sector, including an analysis of critical policy issues necessary for the future development of the area and significant safety gains for all. We argue that there is a need to establish the sports injury problem as a critical component of general global health policy agendas, and to introduce sports safety as a mandatory component of all sustainable sports organizations. We conclude that the establishment of an explicit intersection between science and policy making is necessary for the future development of sports and the necessary safety gains required for all participants around the world. The Safe Sports International safety promotion programme is outlined as an example of an international organization active within this arena.

Attitudes towards visual correction in sport: What coaches, physical education teachers and sports physicians think.

PubMed

Zeri, F; Livi, S; Maffioletti, S

2011-04-01

To evaluate sport professionals' attitudes towards visual correction in sport. A questionnaire was handed out in schools, gyms, sports centres and universities, to coaches, physical education teachers and final year students of motor science. The questionnaire was given to one group of sport physicians prior to a 1-day scientific update course on the benefits of contact lenses (CLs) in sport. At the end of the course, certain questions from the questionnaire were given out again in order to evaluate the effect of the update on their opinions. A total of 245 questionnaires were collected. The interviewees stated that correcting a vision defect during sports practice was important, but their propensity to suggest CLs for sport, though still rather high in value, showed a statistically significant drop. This drop did not occur if the CLs were recommended for competitive sports. This trend remained unchanged if a specific judgement was requested for the adolescent category. The tendency to suggest CLs was higher in CL wearers as compared to non-wearers. The sport with the lowest recommendation of CLs was swimming. In the sample of sports physicians, a specific education on the subject of CLs increased the propensity to adopt CLs in sports. The main "actors" in the sports sector regard correcting a vision defect during sport to be important. Nevertheless, their tendency to suggest CLs is significantly lower. Works that make these categories aware of the benefits of CLs in sport can certainly help to fill this gap. Copyright © 2010 British Contact Lens Association. Published by Elsevier Ltd.

Based on a population of 122 severely injured patients the causes of paragliding accidents and the patterns of injury are analyzed. A questionnaire is used to establish a sport-specific profile for the paragliding pilot. The lower limbs (55.7%) and the lower parts of the spine (45.9%) are the most frequently injured parts of the body. There is a high risk of multiple injuries after a single accident because of the tremendous axial power. The standard of equipment is good in over 90% of the cases. Insufficient training and failure to take account of geographical and meteorological conditions are the main determinants of accidents sustained by paragliders, most of whom are young. Nevertheless, 80% of our patients want to continue paragliding. Finally some advice is given on how to prevent paragliding accidents and injuries.

Monitoring on the Move

NASA Technical Reports Server (NTRS)

2000-01-01

The MyoMonitor EMG system was developed by Delsys, Inc. under SBIR funding from Johnson Space Center. It is a wearable four-channel device that can monitor muscle performance. Presently, its application include rehabilitative therapy, injury prevention, sports medicine, exercise training, and various other muscle monitoring activities. The MyoMonitor uses a two-bar single differential electrode. Due to the electrode-skin interface in traditional EMG equipment, during rigorous muscular activity, the movement of the skin causes the electrode detection surfaces to become compromised. The MyoMonitor eliminates this problem, enabling a wide array of applications and experiments during intense muscular activity. The ability to make such recordings, for example, enables novel experiments aboard the International Space Station for investigating the effect of microgravity on muscle performance. Product still commercially available as of March 2002.

In a period extending from July 1973 to December 1975, seven fatal hang glider accidents were recorded in Colorado, all among experienced pilots. In addition, 11 serious nonfatal injuries were reported, which may represent only a fraction of those occurring. Accidents were noted to be multifactorial, caused by (1) pilot error, (2) equipment failure, (3) terrain hazards, and (4) possible design shortcomings. Accidents can be expected to decline in frequency with improved pilot training programs, grading and regulation of sites, and standardized safety clothing. No doubt over time, the less safe standard Rogallo wing will be replaced by the more stable Superkites and controlled collapsibles, which offer a higher safety margin. In the last analysis, this sport will remain a popular yet high risk endeavor (Figs. 2 through 5).

Ethical issues concerning New Zealand sports doctors

Anderson, L; Gerrard, D

2005-01-01

Success in sport can provide a source of national pride for a society, and vast financial and personal rewards for an individual athlete. It is therefore not surprising that many athletes will go to great lengths in pursuit of success. The provision of healthcare for elite sports people has the potential to create many ethical issues for sports doctors; however there has been little discussion of them to date. This study highlights these issues. Respondents to a questionnaire identified many ethical matters, common to other areas of medicine. However they also raised problems unique to sports medicine. Some of these ethical difficulties arise out of the place of the sports doctor within the hierarchy of sport. Yet others arise out of the special relationship between sports doctors and individual players/athletes. This study raises some important questions regarding the governance of healthcare in sport, and what support and guidance is available to sports doctors. As medical and scientific intervention in sport escalates, there is a risk that demands for enhanced performance may compromise the health of the athlete, and the role the sports doctor plays remains a critical question.

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.

Childhood obesity is rapidly increasing in China, with rates doubling between 2000 and 2010. Several large, epidemiological studies have shown boys to be consistently more likely to be obese than girls. The aim of this study was to investigate gender differences in the home environment and parenting practices related to childhood obesity. A cross-sectional survey using a convenience sampling of 522 (86.1% response rate) primary caregivers of children ages 2-10 years was conducted in four locations in Nanchang, China, in the spring of 2013 using face-to-face, anonymous questionnaires. Boys were significantly (p<0.05) more likely than girls to watch more television (TV) per week, be allowed to have snacks/sweets or soft drinks without permission, and to have sugary drinks at snacks and meals. Girls were significantly more likely than boys to have parental encouragement and support for physical activity, participate in organized sports/group activities, and have fresh fruits accessible. Parents also believed that boys eat too much junk foods or their favorite foods if not controlled. Few differences were noted in the actual physical environment in the home, including access to sports equipment, junk food availability, and access to media. RESULTS indicate that parents tend to be more permissive with boys than girls, allowing them access to unhealthy foods and more TV time. These differences may contribute to the higher prevalence of obesity in boys in China.

Skateboarding injuries: An updated review.

PubMed

Shuman, Kristin M; Meyers, Michael C

2015-07-01

This in-depth literature review shows that skateboarding has experienced intermittent periods of popularity, with an estimated 6-15 million skateboarders in the US currently involved at all levels of recreational play and competition. Head trauma accounts for ∼ 3.5-13.1% of all skateboarding injuries. Injury occurs most often to the upper extremity (55-63%), whereas thoracoabdominal and spine injuries account for 1.5-2.9% of all trauma and lower extremity injuries occur 17-26% of the time. Few fatal injuries (1.1%) have been reported, oftentimes resulting from traumatic head injuries incurred from collisions with motor vehicles. Although skateparks may be perceived as a safer alternative to street skateboarding, injuries still occur when the skateboarder collides with an object or falls from the board. Factors leading to trauma include fatigue and overuse, age and skill level, inadequate medical care, environmental conditions, equipment concerns, lack of fitness and training, and the detrimental behavior of the competitor. Although not all skateboarding injuries are avoidable, numerous opportunities exist to instill safety involving education, instruction, and supervision and the proper use of protective gear to reduce predisposition to trauma. Future research recommendations include a more standardized data collection system, as well as an increased focus on kinetic analysis of the sport. Legislation involving helmet laws and the increased investment in a safer environment for the skateboarder may also assist in reducing injury in this sport.

As participation in wheelchair sports increases, the need of quantitative assessment of biomechanical performance indicators and of sports- and population-specific training protocols has become central. The present study focuses on junior wheelchair basketball and aims at (i) proposing a method to identify biomechanical performance indicators of wheelchair propulsion using an instrumented in-field test and (ii) developing a training program specific for the considered population and assessing its efficacy using the proposed method. Twelve athletes (10 M, 2 F, age = 17.1 ± 2.7 years, years of practice = 4.5 ± 1.8) equipped with wheelchair- and wrist-mounted inertial sensors performed a 20-metre sprint test. Biomechanical parameters related to propulsion timing, progression force, and coordination were estimated from the measured accelerations and used in a regression model where the time to complete the test was set as dependent variable. Force- and coordination-related parameters accounted for 80% of the dependent variable variance. Based on these results, a training program was designed and administered for three months to six of the athletes (the others acting as control group). The biomechanical indicators proved to be effective in providing additional information about the wheelchair propulsion technique with respect to the final test outcome and demonstrated the efficacy of the developed program.

Context: Chronic traumatic encephalopathy (CTE) is a rare progressive neurologic disorder that can manifest as a combination of cognitive, mood and behavioral, and neurologic symptoms. Despite clinically apparent symptoms, there is no imaging or other diagnostic test that can confirm diagnosis in living subjects. Diagnosis can only be confirmed postmortem by specific histopathologic features within the brain tissue identified on autopsy. CTE represents a unique tauopathy that is distinct from other neurodegenerative diseases. Evidence Acquisition: PubMed was searched from 1990 to 2013 for sport concussion and chronic traumatic encephalopathy. Articles were also identified from bibliographies of recent reviews and consensus statements. Study Design: Clinical review. Level of Evidence: Level 5. Results: Although CTE is postulated to occur as a result of repetitive mild traumatic brain injury, the specific etiology and risk factors have not yet been elucidated, and postmortem diagnosis makes causality difficult to determine. Conclusion: When counseling athletes and families about the potential association of recurrent concussions and the development of CTE, discussion of proper management of concussion is cornerstone. Unfortunately, to date, there is no equipment that can prevent concussions; however, rule changes and legislation may decrease the risk. It is imperative that return to play is medically supervised by a provider trained in the management of concussion and begins only once symptoms have resolved. In addition, athletes with permanent symptoms should be retired from contact sport. PMID:25177414

In order to investigate the behaviour of athletes in choosing sports, we analyse data from part of the We-Sport database, a vertical social network that links athletes through sports. In particular, we explore connections between people sharing common sports and the role of age and gender by applying "network science" approaches and methods. The results show a disassortative tendency of athletes in choosing sports, a negative correlation between age and number of chosen sports and a positive correlation between age of connected athletes. Some interesting patterns of connection between age classes are depicted. In addition, we propose a method to classify sports, based on the analyses of the behaviour of people practising them. Thanks to this brand new classifications, we highlight the links of class of sports and their unexpected features. We emphasise some gender dependency affinity in choosing sport classes.

The aim of this study was to evaluate mid-term return to recreational sport in general population and identify factors related with sports return. Retrospective evaluation of 99 recreational sports players (Tegner score of 6) with ACL arthroscopic reconstructions with hamstring autograft, between 2006-2011. 74 male and 25 female with middle age of 30 years (14-52). We made a questionnaire focused on sports level before injury and after surgery, and different scales: Lysholm, Tegner Activity Level, IKDC and a Likert scale for quantify their motivation for return to sports. With a medium follow-up of 36 months, 90 patients (91.9 %) had returned to recreational sport. 51 (51.52 %) had returned to sports at the same level, and these are those with lower BMI (average 23), higher IKDC and Lysholm scores (p < 0.01) and also they believe that sport is an important activity. Only 9 % of patients left sports. They were principally male athletes (88 %), with higher medium age (32), lesser time between injury and surgery (22 months), higher BMI (26), in comparison with athletes that return to sports. The results suggest good mid-term return to recreational sports in general population. The following factors had a statistically significant influence on the return to sports activity: type of sport, sex and functional state of the operated knee (IKDC-Lysholm). Psychological and social factors may have a fundamental influence on return to sports activity.

Sport and Transgender People: A Systematic Review of the Literature Relating to Sport Participation and Competitive Sport Policies.

Whether transgender people should be able to compete in sport in accordance with their gender identity is a widely contested question within the literature and among sport organisations, fellow competitors and spectators. Owing to concerns surrounding transgender people (especially transgender female individuals) having an athletic advantage, several sport organisations place restrictions on transgender competitors (e.g. must have undergone gender-confirming surgery). In addition, some transgender people who engage in sport, both competitively and for leisure, report discrimination and victimisation. To the authors' knowledge, there has been no systematic review of the literature pertaining to sport participation or competitive sport policies in transgender people. Therefore, this review aimed to address this gap in the literature. Eight research articles and 31 sport policies were reviewed. In relation to sport-related physical activity, this review found the lack of inclusive and comfortable environments to be the primary barrier to participation for transgender people. This review also found transgender people had a mostly negative experience in competitive sports because of the restrictions the sport's policy placed on them. The majority of transgender competitive sport policies that were reviewed were not evidence based. Currently, there is no direct or consistent research suggesting transgender female individuals (or male individuals) have an athletic advantage at any stage of their transition (e.g. cross-sex hormones, gender-confirming surgery) and, therefore, competitive sport policies that place restrictions on transgender people need to be considered and potentially revised.

Sports activity after surgical AC joint stabilisation has not been comprehensively evaluated to date. The aim of this study was to determine rate, level and time to return to sports after AC joint stabilisation and to identify the influence of overhead sports on post-operative sports activity. In this retrospective case series, a total of 68 patients with a high-grade AC joint dislocation (Rockwood type V) were stabilised using a single TightRope technique. Fifty-five patients (80.9 %) with median age of 42.0 (range, 18-65) years completed questionnaires regarding sports activity before and after surgery. Clinical outcome and complications were also evaluated. Forty-three patients participated in sports regularly before injury. Their sports activity was rated according to Allain, and non-overhead and overhead sports were differentiated. At median follow-up of 24 (18-45) months, 41 of 43 patients (95.3 %) had returned to sports. 63 % returned to the same sports activity as before injury. 16.3 % needed to adapt the type of sports to reduce demanding activities. 11.6 % reduced the frequency and 32.5 % the intensity of sports. The median time to return to sports was 9.5 (3-18) months. Overhead athletes (Allain Type III and IV) had to reduce their sports activity significantly more often (11.8 vs. 53.8 %; p = 0.011) and needed more time to return to sports (9.5 vs. 4.5 months; p = 0.009). After stabilisation of AC joint dislocation, the majority of patients returned to sports after a substantial period of time. Overhead athletes, in particular, required more time and had to considerably reduce their sports activity. The findings impact therapeutic decision-making after AC joint injury and help with the prognosis and assessment of rehabilitation progress. IV.

Overuse injuries in youth athletes are becoming increasingly common which may be a result of the prevalence of year-round specialized sport participation. Previous research has identified sport volume recommendations related to months per year, hours per week, and simultaneous participation in multiple sports leagues. Coaches are a primary influence on a youth athlete's decision to specialize in a single sport. Therefore, identifying coaches' baseline beliefs and perceptions is important for developing strategies to educate coaches about safe sport participation. A total of 253 youth sport coaches (207 males) completed an anonymous online questionnaire regarding knowledge of sport volume recommendations and attitudes and beliefs regarding sport specialization. Eligible participants were required to serve as a head or assistant coach of a youth sport team in the past 12 months whose members were between the ages of 12 and 18. Most coaches were unaware of recommendations regarding the maximum number of months per year (79.4%), hours per week in one sport (79.3%), or number of simultaneous leagues for an athlete to participate in to reduce injury (77.6%). Fewer than half (43.2%) of all coaches were "very" or "extremely" concerned about the risk of injury in youth sports. A majority (60.1%) believed that sport specialization was either "quite a bit" or "a great deal" of a problem. Two-thirds (67.2%) responded that year-round participation in a single sport was either "very" or "extremely" likely to increase an athlete's risk of injury. Although the responses to this survey were predominantly from coaches from one state, our results suggest that coaches are unaware of sport volume recommendations but are concerned about specialization. Future efforts are needed to communicate these recommendations to coaches in order to reduce the risk of overuse injury in youth sports.

Spatial accessibility to specific sport facilities and corresponding sport practice: the RECORD Study

PubMed Central

2013-01-01

Background Physical activity is considered as a major component of a healthy lifestyle. However, few studies have examined the relationships between the spatial accessibility to sport facilities and sport practice with a sufficient degree of specificity. The aim of this study was to investigate the associations between the spatial accessibility to specific types of sports facilities and the practice of the corresponding sports after carefully controlling for various individual socio-demographic characteristics and neighborhood socioeconomic variables. Methods Data from the RECORD Study involving 7290 participants recruited in 2007–2008, aged 30–79 years, and residing in the Paris metropolitan area were analyzed. Four categories of sports were studied: team sports, racket sports, swimming and related activities, and fitness. Spatial accessibility to sport facilities was measured with two complementary approaches that both take into account the street network (distance to the nearest facility and count of facilities around the dwelling). Associations between the spatial accessibility to sport facilities and the practice of the corresponding sports were assessed using multilevel logistic regression after adjusting for individual and contextual characteristics. Results High individual education and high household income were associated with the practice of racket sports, swimming or related activities, and fitness over the previous 7 days. The spatial accessibility to swimming pools was associated with swimming and related sports, even after adjustment for individual/contextual factors. The spatial accessibility to facilities was not related to the practice of other sports. High neighborhood income was associated with the practice of a racket sport and fitness. Conclusions Accessibility is a multi-dimensional concept that integrates educational, financial, and geographical aspects. Our work supports the evidence that strategies to increase participation in sport activities should improve the spatial and financial access to specific facilities, but also address educational disparities in sport practice.

2000-04-01

The impact of federal anti-discrimination laws such as Title IX and the Amateur Sports Act have opened the doors of sport participation opportunity to girls and women in sports over the last 25 years. Such participation has created new and more lucrative consumer markets for sporting goods manufactures, as well as college and professional sports teams. The prospect of economic gain has created significant social changes: Women are now being encouraged to participate in sports and embrace the resulting benefits, and the general public is showing increased support for gender equity in sports.

2012-03-01

The built environment can influence sports practice. The objective of this study was to examine the association between proximity (< 500m) to sports facilities and participation in sports. We evaluated 1,175 13-year-olds (54% girls) enrolled in public and private schools in Porto, Portugal. Sports activity was assessed using a self-completed questionnaire. The adolescents' residences and sports facilities were georeferenced. A matrix of distances from each residence to the facilities was calculated. For the majority (87%) of the adolescents, there was at least one sports facility close to their place of residence. No statistically significant differences were found in participation in sports based on proximity to facilities (< 500m vs. > 500m); the proportions were 44% vs. 38% (p = 0.414) in girls and 72% vs. 61% (p = 0.094) in boys. In conclusion, proximity to sports facilities was not significantly associated with participation in sports.

Parents' perceptions of child-to-parent socialization in organized youth sport.

Dorsch, Travis E; Smith, Alan L; McDonough, Meghan H

2009-08-01

The purpose of this study was to enhance understanding of how parents are socialized by their children's organized youth sport participation. Five semistructured focus groups were conducted with youth sport parents (N = 26) and analyzed using qualitative methods based on Strauss and Corbin (1998). Sixty-three underlying themes reflected parents' perceived socialization experiences resulting from their children's organized youth sport participation. Each theme represented 1 of 11 subcategories of parental change, which were subsumed within four broad categories of parent sport socialization (behavior, cognition, affect, relationships). Each category of parental change was interconnected with the other three categories. Moreover, six potential moderators of parent sport socialization were documented, namely, child age, parent past sport experience, parent and child gender, child temperament, community sport context, and type of sport setting (individual or team). Together, these findings enhance understanding of parent sport socialization processes and outcomes, thus opening avenues for future research on parents in the youth sport setting.

School-based extracurricular sport remains an effective strategy to increase physical activity. However, school sport is often limited to a small number of elite athletes. Few schools provide more inclusive sport programs that offer a wider array of activities regardless of ability. The aim of this study was to examine school sport participation in middle schools (ages 11-14) with contrasting school sport delivery strategies (intramural vs. interscholastic). Data were obtained through an online survey administered to students at four public middle schools (grades 6-8) in a southeastern US city (n = 2,582). More students participated in school sports at intramural schools. Boys were more likely to participate in after-school sports at intramural schools. Low-income and Black children, two groups at greater risk of physical inactivity and other negative outcomes, had greater participation in intramural programs. After-school intramural sports in middle school is a promising strategy for increasing sport participation.

Aging, physical activity and sports injuries. An overview of common sports injuries in the elderly.

PubMed

Kallinen, M; Markku, A

1995-07-01

Illness and aging both cause many structural and functional alterations in the human body, rendering elderly people liable to overloading of the musculoskeletal and cardiovascular systems. It should, however, be kept in mind that immobilisation and inactivity have even more deleterious effects on structures and functions in the elderly than in younger adults. Most physically active elderly people are selected individuals with respect to their superior health and physical capacity compared with inactive persons of the same age, thus making it possible to further improve their physical capacity. They will, however, be affected by some of the drawbacks of physical overloading, mostly due to the diminished ability of aging body systems to adapt to high levels of loading. The safety margin of an exercise dose tends to decline with aging. Exertional injuries are common among the elderly, and are connected mostly with degenerative aging processes. Acute injuries are common in those elderly people participating in sport activities which demand high coordination, reaction time, and balance capabilities, such as ball games, down-hill skiing, and gymnastics. Muscle has been reported to be the most commonly acutely injured tissue among active elderly athletes. The lower extremities are the most susceptible to injury. A large proportion of injuries (acute and exertional) are mild and can be treated by brief cessation of training and competition activities. Some of the injuries are, however, long term and cause disability not only during training and competition, but also in the normal activities of daily living. It is important that these injuries are treated as soon as possible and in the most effective way, similarly to injuries suffered by younger people. In treating elderly people, it is most important to avoid the detrimental effects of immobilisation; this requires active treatment and rehabilitation with compensatory exercise therapy. The best 'treatment' for sports-related injuries is prevention. Good agility, technical skills, and cardiovascular and musculoskeletal fitness are important in injury prevention among the elderly. Appropriate training programmes, the use of safe and familiar equipment, careful warming up and cooling down, multiphasic training [including the training of neurophysiological functions (balance, coordination and reaction time)] and muscle strength are essential aspects of injury prevention.

2016-01-01

Introduction Most high-grade renal injuries (American Association for Surgery of Trauma (AAST) grades III–V) result from motor vehicle collisions associated with numerous concomitant injuries. Sports-related blunt renal injury tends to have a different mechanism, a solitary blow to the flank. We hypothesized that high-grade renal injury is often isolated in sports-related renal trauma. Material and methods We identified patients with AAST grades III–V blunt renal injuries from four level 1 trauma centres across the United States between 1/2005 and 1/2014. Patients were divided into “Sport” or “Non-sport” related groups. Outcomes included rates of hypotension (systolic blood pressure <90 mm Hg), tachycardia (>110 bpm), concomitant abdominal injury, and procedural/surgical intervention between sports and non-sports related injury. Results 320 patients met study criteria. 18% (59) were sports-related injuries with the most common mechanisms being skiing, snowboarding and contact sports (25%, 25%, and 24%, respectively). Median age was 24 years for sports and 30 years for non-sports related renal injuries (p = 0.049). Males were more commonly involved in sports related injuries (85% vs. 72%, p = 0.011). Median injury severity score was lower for sports related injuries (10 vs. 27, p < 0.001). There was no difference in renal abbreviated injury scale scores. Sports related trauma was more likely to be isolated without other significant injury (69% vs. 39% (p < 0.001)). Haemodynamic instability was present in 40% and 51% of sports and non-sports renal injuries (p = 0.30). Sports injuries had lower transfusion (7% vs. 47%, p < 0.001) and lower mortality rates (0% vs. 6%, p = 0.004). There was no difference in renal-specific procedural interventions between the two groups (17% sports vs. 18% non-sports, p = 0.95). Conclusions High-grade sports-related blunt renal trauma is more likely to occur in isolation without other abdominal or thoracic injuries and clinicians must have a high suspicion of renal injury with significant blows to the flank during sports activities.

It's not how much you play, but how much you enjoy the game: the longitudinal associations between adolescents' self-esteem and the frequency versus enjoyment of involvement in sports.

PubMed

Adachi, Paul J C; Willoughby, Teena

2014-01-01

The frequency of involvement in sports often has been concurrently and longitudinally associated with higher self-esteem. The interpretation of this association consistently has been framed as involvement in sports leading to higher levels of self-esteem over time (i.e., socialization effect), although no studies have tested whether higher levels of self-esteem lead to increased involvement in sports over time (i.e., selection effect). Another important aspect of involvement in sports that may be related to self-esteem is the degree to which youth enjoy sports. However, this aspect has received much less attention. To address these gaps in the literature, we first examined the bidirectional effects between self-esteem and the frequency of involvement in sports with 1,492 adolescents (50.8 % female; 92.4 % Canadian-born) over 4 years. Higher levels of self-esteem predicted greater involvement in sports over time, but greater involvement in sports did not predict higher levels of self-esteem over time, offering support only for selection effects. We then tested the bidirectional effects between the enjoyment of sports and self-esteem and found evidence of both socialization and selection effects. Specifically, greater enjoyment of sports predicted higher self-esteem over time, and higher self-esteem predicted greater enjoyment of sports over time. These novel findings suggest that adolescents with higher self-esteem play sports more frequently and enjoy sports more than adolescents with lower self-esteem. In addition, the degree to which adolescents enjoy sports may be more important for increasing self-esteem than the frequency with which adolescents play sports.

Population estimates of Australian children's exposure to food and beverage sponsorship of sports clubs.

Sponsorship by manufacturers of unhealthy food can undermine the health promoting goals of sport. This study aimed to describe Australian children's exposure to organised sport, and compare time spent in specific sports with patterns of sponsorship of children's sport identified in previous studies. Cross-sectional survey on children's sport participation collected by proxy report using a random-digit-dialling survey of 3416 parents. Data from the 2009/10 Australian Sports Commission's Exercise, Recreation and Sport Survey were used to calculate weekly total person-time exposure to sports for Australian children, as a product of median weekly exposure (minutes) and the number of children participating. Exposures for children in NSW were calculated based on population distribution. Based on a previous survey of sport clubs in NSW, cumulative weekly exposure to food/beverage sponsorship at sports clubs was estimated for children living in NSW. 77.3% of Australian children aged 5-14 participated in organised sport. In NSW, weekly total person-time exposure for children was highest for outdoor soccer (91,200 children×median frequency of 2 sessions per week of 1h duration=182,400h/week). Considering rates of sponsorship at different sports, children would be exposed to food/beverage sponsorship to the greatest extent for rugby league and outdoor cricket. Children's high frequency of participation in organised sport and time spent engaging in these activities highlights the potentially huge reach of food/beverage sponsorship promotions. Policy interventions to limit children's exposure to this sponsorship should target those sports that have both the highest levels of children's participation and food/beverage sponsorship arrangements.

Marlier, Mathieu; Cardon, Greet; De Bourdeaudhuij, Ilse; Willem, Annick

2014-12-01

Recent evidence showed that community capacity building is one of the key methods to reach health improvements within disadvantaged communities. Physical activity and sports participation are important means to reach health improvements. This study investigates a capacity building method which aims at increasing sports participation in the community, especially for individuals at higher risk of sports deprivation. The main aims of the present study, are the following: (1) to examine differences in sports participation between individuals living in communities implementing a sports-based capacity building program and individuals living in communities without such capacity building program and (2) to investigate if the community sports program reaches the individuals known to experience higher barriers to engage in sports. In Flanders, Belgium, five disadvantaged urban communities implementing the community capacity building program (program communities) and four without (control communities) were selected based on similarity of sociodemographic and environmental characteristics. Two hundred adults (aged 18-56 years) per community were randomly selected and visited at home to fill out a questionnaire on sociodemographics, sports participation, and the community sports program. A sample of 414 adults participated in the study. Results showed that adults from program communities reported on average 96 min/week more participation in sports than their counterparts living in control communities. Furthermore, 61.3% of the individuals of program communities indicated to engage in sports, whereas in control communities, this was only 42.4%. Respondents at higher risk of sports deprivation also engaged in significantly more sports participation in program communities than those in control communities. This difference was also noted for groups that are not related with sports deprivation. These results are promising and plead for a community capacity building approach to increase sports participation in disadvantaged communities.

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.

Models of sport development often support the assumption that young athletes' psychosocial experiences differ as a result of seemingly minor variations in how their sport activities are designed (eg, participating in team or individual sport; sampling many sports or specialising at an early age). This review was conducted to systematically search sport literature and explore how the design of sport activities relates to psychosocial outcomes. Systematic search, followed by data extraction and synthesis. The Preferred Reporting Items for Systematic reviews and Meta-Analyses guidelines were applied and a coding sheet was used to extract article information and code for risk of bias. Academic databases and manual search of peer-reviewed journals. Search criteria determined eligibility primarily based on the sample (eg, ages 7 through 17 years) and study design (eg, measured psychosocial constructs). 35 studies were located and were classified within three categories: (1) sport types, (2) sport settings, and (3) individual patterns of sport involvement. These studies represented a wide range of scores when assessed for risk of bias and involved an array of psychosocial constructs, with the most prevalent investigations predicting outcomes such as youth development, self-esteem and depression by comparing (1) team or individual sport participants and (2) youth with varying amounts of sport involvement. As variations in sport activities impact youth sport experiences, it is vital for researchers to carefully describe and study these factors, while practitioners may use the current findings when designing youth sport programmes.

Who Wants to Play? Sport Motivation Trajectories, Sport Participation, and the Development of Depressive Symptoms.

PubMed

Wang, Ming-Te; Chow, Angela; Amemiya, Jamie

2017-09-01

Although sport involvement has the potential to enhance psychological wellbeing, studies have suggested that motivation to participate in sports activities declines across childhood and adolescence. This study incorporated expectancy-value theory to model children's sport ability self-concept and subjective task values trajectories from first to twelfth grade. Additionally, it examined if sport motivation trajectories predicted individual and team-based sport participation and whether sport participation in turn reduced the development of depressive symptoms. Data were drawn from the Childhood and Beyond Study, a cross-sequential longitudinal study comprised of three cohorts (N = 1065; 49% male; 92% European American; M ages for youngest, middle, and oldest cohorts at the first wave were 6.42, 7.39, and 9.36 years, respectively). Results revealed four trajectories of students' co-development of sport self-concept and task values: congruent stable high, incongruent stable high, middle school decreasing, and decreasing. Trajectory membership predicted individual and team-based sports participation, but only team-based sport participation predicted faster declines in depressive symptoms. The use of a person-centered approach enabled us to identify heterogeneity in trajectories of sport motivation that can aid in the development of nuanced strategies to increase students' motivation to participate in sports.

Sports participation is a major ally for the promotion of physical activity. However, sports injuries are important adverse effects of sports participation and should be monitored in sports populations. The purpose of this paper is to review the basic concepts of injury monitoring and discuss the implementation of these concepts in practice. The aspects discussed are: (1) sports injury definition; (2) classification of sports injuries; (3) population at risk, prevalence, and incidence; (4) severity measures; (5) economic costs; (6) systems developed to monitor sports injuries; and (7) online technology. Only with reliable monitoring systems applied in a continuous and long-term manner will it be possible to identify the burden of injuries, to identify the possible cases at an early stage, to implement early interventions, and to generate data for sports injury prevention. The implementation of sports injuries monitoring systems in practice is strongly recommended. PMID:26537807

Do youth sports prevent pediatric obesity? A systematic review and commentary

Nelson, Toben F.; Stovitz, Steven D.; Thomas, Megan; LaVoi, Nicole M.; Bauer, Katherine W.; Neumark-Sztainer, Dianne

2015-01-01

Sport is a promising setting for obesity prevention among youth, but little is known about whether it prevents obesity. We reviewed research comparing sport participants with non-participants on weight status, physical activity and diet. Among nineteen studies we found no clear pattern of association between body weight and sport participation. Among seventeen studies we found that sport participants are more physically active than those who do not participate. Seven studies examined the relationship between sport participation and diet and found that sport participation is associated with more fruit, vegetable and milk consumption, but also more fast food and sugar sweetened beverage consumption and greater overall calorie intake. It is unclear from these results whether sports programs, as currently offered, protect youth from becoming overweight or obese. Additional research may foster understanding about how sport, and youth sport settings, can help promote energy balance and healthy body weight. PMID:22071397

In a retrospective study with a population over 65 years, sports activity was conducted 6 years after cruciate retaining (CR) total condylar knee arthroplasty (TKA) with rotating platform (RP). Eighty-one Patients (71.8±5.4years) were examined at follow-up 6.4±0.9 years postoperative. Sport was practiced 5.3 hours every week in mean. Patients were active in sports 3.5times per week. Twenty-five percent performed high impact sports, 47% medium impact sports and 52% low impact sports at follow-up. In KOOS sports 60±28 was reached, in WOMAC 12.1±15.1. It can be concluded that in this population 50% of patients were active in medium and low impact sport 6 years after surgery. However, a quarter of patients were also active in high impact sports.

Activating Public Space: How to Promote Physical Activity in Urban Environment

NASA Astrophysics Data System (ADS)

Kostrzewska, Małgorzata

2017-10-01

Physical activity is an essential component of a healthy lifestyle. The quality and equipment of urban public space plays an important role in promoting physical activity among people (residents, tourists). In order for recreation and sports activities to be undertaken willingly, in a safe and comprehensive manner, certain spatial conditions and requirements must be met. The distinctive feature of contemporary large cities is the disappearance of local, neighbourly relations, and the consequent loneliness, alienation, and atomization of the residents. Thus, the design of public spaces should be an expression of the values of social inclusion and integration. A properly designed urban space would encourage people to leave their homes and integrate, also by undertaking different forms of physical activities. This, in turn, can lead to raising the quality of the space, especially in the context of its “familiarization” and “domestication”. The aim of the research was to identify the architectural and urban features of the public spaces of contemporary cities that can contribute to the promotion of physical activity. The paper presents the research results and the case studies of such spatial solutions and examples of good practices, which invite residents to undertake different forms of physical activities in public spaces. The issue of the integrating, inclusionary, and social function of physical recreation and sport is discussed as well, and so are the possibilities of translating these values into physical characteristics of an urban space. The main conclusions are that taking into account the diverse needs of different social groups, participation in the design and construction process, aesthetic and interesting design, vicinity of the residence, open access for all age groups and the disabled would be the most important spatial determinants of a properly designed, physically activating public space. Strategies of planning the sports and recreation infrastructure should also make sure of their multifunctionality and variability in time to adjust it to the changing needs of the residents.

A cross-sectional study that targeted a total of 43,630 pupils in Niigata City, Japan was performed. The objective of the study was to evaluate the association between sports activities and low back pain (LBP) in childhood and adolescence in Japan. Regarding risk factors of LBP, a large number of studies have been conducted that have examined gender differences, height and weight, body mass index, sports time, differences in lifestyle, family history, and mental factors; however, no definitive conclusion has yet been made. A questionnaire survey was conducted using 43,630 pupils, including all elementary school pupils from the fourth to sixth grade (21,893 pupils) and all junior high pupils from the first to third year (21,737 pupils) in Niigata City (population of 785,067). 26,766 pupils who were determined to have valid responses (valid response rate 61.3%) were analyzed. Among the 26,766 pupils with valid responses, 2,591 (9.7%) had LBP at the time of the survey, and 8,588 (32.1%) had a history of LBP. The pupils were divided between those who did not participate in sports activities except the physical education in school (No sports group: 5,486, 20.5%) and those who participated in sports activities (Sports group: 21,280, 79.5%), and the difference in lifetime prevalence between No sports group and Sports group was examined. The odds ratio for LBP according to sports activity was calculated by multiple logistic regression analysis adjusted for gender, age, and body mass index. In addition, the severity of LBP was divided into three levels (Level 1: no limitation in any activity, Level 2: necessary to refrain from participating in sports and physical activities, and Level 3: necessary to be absent from school), and Levels 2 and 3 were defined as severe LBP; the severity was compared between No sports group and Sports group and in each sport's items. Moreover, in Sports group, the amount of time spent participating in sports activities were divided into three groups (Group 1: less than 6 h per week, Group 2: 6-12 h per week, and Group 3: 12.1 h per week or more), and the dose-response between the amount of time spent participating in sports activities and the occurrence of LBP were compared. In No sports group, 21.3% experienced a history of LBP; in Sports group, 34.9% experienced LBP (P < 0.001). In comparison to No sports group, the odds ratio was significantly higher for Sports group (1.57), and also significantly higher for most of the sports items. The severity of LBP was significantly higher in Sports group (20.1 vs. 3.2%, P < 0.001). The amount of time spent participating in sports activities averaged 9.8 h per week, and a history of LBP significantly increased in the group which spent a longer time participating in sports activities (odds ratio 1.43 in Group 3). These findings suggest that sports activity is possible risk factors for the occurrence of LBP, and it might increase the risk for LBP in childhood and adolescence.

Sports medicine and drug control programs of the U.S. Olympic Committee.

PubMed

Clarke, K S

1984-05-01

The Amateur Sports Act of 1978 reconstituted the U.S. Olympic Committee ( USOC ), giving it new responsibilities and opportunities as a unifying force in amateur sports, including sports medicine. Sports medicine is the sum of attentions that promote and protect the health of the active person. Olympic sports medicine includes attention to the needs of both the elite athlete and the developing athlete. In some instances the attentions are the same; in others they are not. Those in Olympic sports medicine must thereby reduce the increasing array of general concepts and issues to the applicable specifics of the respective occasion, sport, and individual. The USOC Sports Medicine Program is guided by a 15-person volunteer Sports Medicine Council and implemented by a core Sports Medicine Division staff. Services are provided at the Olympic training centers in Colorado Springs and Lake Placid and extended through a budding network of colleagues in the field to clusters of athletes across the nations. Organizationally , the Division is composed of departments of biomechanics, sports physiology, clinical services, and educational services. Special projects are developed as warranted to provide focal attention to sports psychology, nutrition, chronobiology, vision enhancement, and drug control. The USOC Drug Control Program was born at the 1983 Pan American Games in Caracas after a long gestation period. Drug education in sports has been a frequent activity for the past 20 yr. sometimes focusing on illicit drugs (e.g., marijuana and cocaine) and sometimes on sports performance drugs (e.g., amphetamines and anabolic steroids).(ABSTRACT TRUNCATED AT 250 WORDS)

Associations between sports participation and psychological difficulties during childhood: a two-year follow up.

PubMed

Vella, Stewart A; Cliff, Dylan P; Magee, Christopher A; Okely, Anthony D

2015-05-01

This paper assessed the associations between sports participation and the development of psychological strengths and difficulties during childhood. Two-year follow up study of a sample of 4042 Australian children who were followed from age 8 years to 10 years. Parents reported children's participation in organised sports, and completed the Strengths and Difficulties Questionnaire. Univariate general linear models were used to examine the association between changes in sports participation and psychological strengths and difficulties at 10 years, adjusting for psychological strengths and difficulties at age 8. Children who maintained participation in sport had lower rates of parent-reported psychological difficulties at 10 years compared with children who dropped out of sport. Less internalising problems were also reported for children who participated in organised sports compared to children who dropped out of sports and children who did not participate in sports. These relationships did not differ by BMI, socioeconomic status, or parental education. Greater psychological difficulties are experienced by children who drop out of sports, and greater social and emotional problems are experienced by children who drop out of sports and who do not participate in organised sports. Due consideration should be given to the quality and implementation of sporting programs to ensure that they provide benefits to mental health. Due consideration should also be given to the potential psychological difficulties being experienced by children who drop out of organised sports as a higher level of psychological difficulties may be experienced prior to or subsequent to dropout.

Domb, Benjamin G; Stake, Christine E; Finch, Nathan A; Cramer, T Luke

2014-10-01

Hip arthroscopy is a minimally invasive surgical technique often performed in athletes who want an expeditious return to sport. To the authors' knowledge, no studies in the literature provide a time frame or criteria for return to sport after hip arthroscopy. The purpose of this study was to develop an aggregate recommendation for return to sport after hip arthroscopy based on data assimilated from high-volume hip arthroscopy centers. Twenty-seven orthopedic surgeons from high-volume hip arthroscopy centers completed a survey regarding return to sport after hip arthroscopy. The questionnaire asked surgeons to give a time frame for return to sport and to choose meaningful criteria that an athlete must meet prior to return to sport. Surgeons were asked to categorize various common sports as high, medium, or low risk with regard to the hip. The aggregate results were used to create standardized recommendations for time, criteria, and risk for return to competitive sports. Regarding time frame for return to sport, 70% of surgeons recommended 12 to 20 weeks. In addressing criteria for return to sport, 85% of surgeons recommended that patients need to be able to reproduce all motions involved in their sport without pain. A majority of surgeons recommended criteria of pain-free running, jumping, lateral agility drills, and single-leg squats. Finally, surgeons categorized sports requiring the most movement and impact of the hip joint (football, basketball, wrestling, and martial arts) as high-risk sports. Sports with less impact on the hip, such as golf, were ranked as low risk. Copyright 2014, SLACK Incorporated.

Combining epidemiology and biomechanics in sports injury prevention research: a new approach for selecting suitable controls.

PubMed

Finch, Caroline F; Ullah, Shahid; McIntosh, Andrew S

2011-01-01

Several important methodological issues need to be considered when designing sports injury case-control studies. Major design goals for case-control studies include the accounting for prior injury risk exposure, and optimal definitions of both cases and suitable controls are needed to ensure this. This article reviews methodological aspects of published sports injury case-control studies, particularly with regard to the selection of controls. It argues for a new approach towards selecting controls for case-control studies that draws on an interface between epidemiological and biomechanical concepts. A review was conducted to identify sport injury case-control studies published in the peer-review literature during 1985-2008. Overall, 32 articles were identified, of which the majority related to upper or lower extremity injuries. Matching considerations were used for control selection in 16 studies. Specific mention of application of biomechanical principles in the selection of appropriate controls was absent from all studies, including those purporting to evaluate the benefits of personal protective equipment to protect against impact injury. This is a problem because it could lead to biased conclusions, as cases and controls are not fully comparable in terms of similar biomechanical impact profiles relating to the injury incident, such as site of the impact on the body. The strength of the conclusions drawn from case-control studies, and the extent to which results can be generalized, is directly influenced by the definition and recruitment of cases and appropriate controls. Future studies should consider the interface between epidemiological and biomechanical concepts when choosing appropriate controls to ensure that proper adjustment of prior exposure to injury risk is made. To provide necessary guidance for the optimal selection of controls in case-control studies of interventions to prevent sports-related impact injury, this review outlines a new case-control selection strategy that reflects the importance of biomechanical considerations, which ensures that controls are selected based on the presence of the same global injury mechanism as the cases. To summarize, the general biomechanical principles that should apply to the selection of controls in future case-control studies are as follows: (i) each control must have been exposed to the same global injury mechanism as the case, (e.g. head impact, fall onto outstretched arm); and (ii) intrinsic (individual) factors (e.g. age, sex, skill level) that might modify the person's response to the relevant biomechanical loads are adjusted when either selecting the controls or are in the analysis phase. The same considerations for control selection apply to other study designs such as matched cohort studies or case-crossover studies.

2006-06-01

As sports scientists, we claim to make a significant contribution to the body of knowledge that influences athletic practice and performance. Is this the reality? At the inaugural congress of the Australian Association for Exercise and Sports Science, a panel of well-credentialed academic experts with experience in the applied environment debated the question, Does sports-science research influence practice? The first task was to define "sports-science research," and it was generally agreed that it is concerned with providing evidence that improves sports performance. When practices are equally effective, sports scientists also have a role in identifying practices that are safer, more time efficient, and more enjoyable. There were varying views on the need for sports-science research to be immediately relevant to coaches or athletes. Most agreed on the importance of communicating the results of sports-science research, not only to the academic community but also to coaches and athletes, and the need to encourage both short- and long-term research. The panelists then listed examples of sports-science research that they believe have influenced practice, as well as strategies to ensure that sports-science research better influences practice.

Anterior shoulder stabilization by Bristow-Latarjet procedure in athletes: return-to-sport and functional outcomes at minimum 2-year follow-up.

The aim of this study was to assess return-to-sport outcomes following the Latarjet-Bristow procedure. This retrospective study included all athletes <50 years old, who underwent a Latarjet-Bristow procedure for anterior shoulder instability in 2009-2012. Main criteria assessments were the number of athletes returning to any sport and the number returning to the same sport at their preinjury level. The main follow-up was 46.8 ± 9.7 months. Forty-seven patients were analyzed, 46 men/1 women, mean age 27.9 ± 7.9 years. Eighteen patients practiced competitive sports and 29 recreational sports. None of them were professional athletes. One hundred percent returned to sports after a mean 6.3 ± 4.3 months. Thirty/47 (63.8 %) patients returned to the same sport at the same level at least and 10/47 (21.3 %) patients changed sport because of their shoulder. Compared to patients who returned to the same sport at the same level, patients who changed sports or returned to a lower level had practiced overhead or forced overhead sports [OR = 4.7 (1.3-16.9), p = 0.02] before surgery, experienced avoidance behavior at the final follow-up (p = 0.002), apprehension (p = 0.00001) and had a worse Western Ontario Shoulder Instability Index score and sub-items (p = 0.003) except for daily activities (p = 0.21). At the final follow-up, 45/47 (95.7 %) patients were still practicing a sport. All the patients returned to sports, most to their preinjury sport at the same level. Patients who practiced an overhead sport were more likely to play at a lower level or to change sport postoperatively. IV, retrospective study-Case series with no comparison group.

PubMed

Glang, Ann; Koester, Michael C; Beaver, Sherry Vondy; Clay, Janet E; McLaughlin, Karen A

2010-03-01

The purpose of this study was to evaluate ACTive: Athletic Concussion Training using Interactive Video Education, an interactive e-learning program designed to train community coaches of youth ages 10-18 in effective sports concussion prevention and management practices. Seventy-five youth sports coaches from across the country completed the study over the Internet. Results of a randomized control trial demonstrated significant differences between treatment and control participants on measures of (a) knowledge about sports concussion, management, and prevention; (b) attitudes about the importance of preventing sports concussion; and (c) intention and self-efficacy in sports concussion management and prevention. The results suggest that ACTive is an effective method of training youth sports coaches who are in an important position to reduce risks associated with sports concussion.

Sports-related concussions - media, science and policy.

Mannix, Rebekah; Meehan, William P; Pascual-Leone, Alvaro

2016-08-01

Although growing awareness about the potential long-term deleterious effects of sport-related concussion has led to increased attention to the risks of collision sports, calls to ban these sports, such as American football, might be premature. Collision sports have a relatively high incidence of concussions, but participation in these sports also confers a host of benefits. In addition, the associated risks of participation, including concussion, have not been definitively shown to outweigh the benefits they provide, and the risk-benefit ratio might vary among individuals. The risks of concussion and repetitive concussions associated with collision sports are unknown in the general population and not well characterized even in elite athlete populations. In this article, we discuss current knowledge on sports-related concussion, its neurological consequences, and implications for regulation of the practice of collision sports.

Participation in ultraendurance sports has been increasing in recent years. This participation growth has been associated with an increase in research focused on such events. While the total amount of research related to these sports remains relatively small compared with other sports, the research growth is encouraging. New sources for research funding for ultraendurance sports should advance the science. In addition to continued opportunities with observational studies, promising areas of investigation remain for experimental studies and research that uses ultraendurance-sport environments as models for studies relevant to wider populations. Insight into the breadth of research opportunities in ultraendurance sports can be gained by reviewing the abstracts published online in the International Journal of Sports Physiology and Performance from the annual Medicine & Science in Ultra-Endurance Sports Conference that took place this year in Chamonix, France.

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.

To investigate the clinical characteristics of acute type A aortic dissection (ATAAD) occurring during a sporting activity. The subjects of this study were 615 patients who underwent surgery for ATAAD between 1990 and 2015. The patients were divided into two groups according to whether the ATAAD was associated with a sporting activity (sports group: n = 25, mean age 62.3 years; non-sports group: n = 590, mean age 63.7 years). Specific activity was assessed in the sports group, and the characteristics and outcomes were compared between the groups. The sports group accounted for 5% of the patients with daytime onset ATAAD (25/479). The most common sport was golf (n = 8), followed by swimming (n = 4), cycling (n = 4), and weight lifting (n = 3). The average diameter of the ascending aorta on preoperative computed tomography was 4.8 cm. The dissection characteristics of the sports group included DeBakey type I (n = 23, 92%) and malperfusion (n = 9, 36%), which were similar to those of the non-sports group. The 30-day mortality rates were 16% (4/25) for the sports group and 8% (49/590) for the non-sports group (P = 0.33). The most common sport associated with ATAAD was golf, followed by swimming cycling, and weight lifting. The findings of this study reinforce that sports-related aortic dissection is not a unique clinical condition of young syndromic patients, but can occur in all age groups.

Estimate the amount of alcohol advertising in sport vs. non-sport programming in Australian free-to-air TV and identify children's viewing audience composition at different times of the day. Alcohol advertising and TV viewing audience data were purchased for free-to-air sport and non-sport TV in Australia for 2012. We counted alcohol advertisements in sport and non-sport TV in daytime (6 am-8.29 pm) and evening periods (8.30 pm-11.59 pm) and estimated viewing audiences for children and young adults (0-4 years, 5-13 years, 14-17 years, 18-29 years). During the daytime, most of the alcohol advertising (87%) was on sport TV. In the evening, most alcohol advertising (86%) was in non-sport TV. There was little difference in the mean number of children (0-17 years) viewing TV in the evening (N = 273,989), compared with the daytime (N = 235,233). In programs containing alcohol advertising, sport TV had a greater mean number of alcohol adverts per hour (mean 1.74, SD = 1.1) than non-sport TV (mean 1.35, SD = .94). Alcohol advertising during the daytime, when large numbers of children are watching TV, is predominantly in free-to-air sport TV. By permitting day-time advertising in sport programs and in any programs from 8.30 pm when many children are still watching TV, current regulations are not protecting children from exposure to alcohol advertising.

To examine U.S. adult knowledge of the sugar content of sports drinks and whether this knowledge and other characteristics are associated with their sports drink consumption. Nonexperimental. Nationally representative 2011 Summer ConsumerStyles survey data. 3929 U.S. adults. The outcome variable was sports drink consumption in the past 7 days. The main exposure variable was knowledge about sports drinks containing sugar. The covariates were sociodemographic characteristics, physical activity, and weight status. Multivariable logistic regression analysis was used to estimate adjusted odds ratios (ORs) for adults consuming sports drinks ≥1 times/wk after controlling for other characteristics. Approximately 22% of adults reported consuming sports drinks ≥1 times/wk. Most adults (71%) agreed that sports drinks contain sugar; however, this agreement was not significantly associated with adults' sports drink consumption. The odds of drinking sports drinks ≥1 times/wk were significantly higher among younger adults aged 18 to 64 years (OR range: 5.46-2.71), males (OR = 2.09), high-school graduates (OR = 1.52), and highly active adults (OR = 2.09). There were disparities in sports drink consumption by sociodemographic characteristics and physical activity level; however, knowledge of sports drinks' sugar content was not associated with consumption. Understanding why some population groups are higher consumers may assist in the development of education, providing those groups with a better understanding of sports drinks' nutritional value and health consequences of excessive sugar consumption in any form.

The risk of dental trauma may increase during sports participation. The purpose of this study was to evaluate the knowledge, attitude, and practices of sports participants concerning sports-related dental trauma and associated emergency/preventive practices. The study included 124 male subjects over 18 years of age participating in contact and non-contact sports in three clubs in the Eastern Province, Saudi Arabia. A questionnaire was used to assess past experience of dental trauma related to sports in addition to the use of a mouth guard and knowledge of related emergency procedures. Outcomes were compared between individuals practicing direct and non-direct contact sports. One third of the participants had experienced dental trauma while playing sports, mostly crown fracture, mobility, and avulsion. Their knowledge of first aid and emergency procedures was inadequate. A significantly higher proportion of non-direct contact sport participants sought the help of a dentist for themselves or others (P = 0.04 and 0.003, respectively). Only 33.9% used mouth guards, with higher odds of mouth guard use associated with participating in direct contact sports and believing a tooth can be lost during sports practice (odds ratio = 5.59 and 5.37, respectively). Educational programs are needed to increase the awareness in sports participants of the risk of dental trauma during sports participation, to improve their knowledge of first aid procedures, and to increase the use of mouth guards.

The 2016 Warwick Agreement on femoroacetabular impingement (FAI) syndrome was convened to build an international, multidisciplinary consensus on the diagnosis and management of patients with FAI syndrome. 22 panel members and 1 patient from 9 countries and 5 different specialties participated in a 1-day consensus meeting on 29 June 2016. Prior to the meeting, 6 questions were agreed on, and recent relevant systematic reviews and seminal literature were circulated. Panel members gave presentations on the topics of the agreed questions at Sports Hip 2016, an open meeting held in the UK on 27-29 June. Presentations were followed by open discussion. At the 1-day consensus meeting, panel members developed statements in response to each question through open discussion; members then scored their level of agreement with each response on a scale of 0-10. Substantial agreement (range 9.5-10) was reached for each of the 6 consensus questions, and the associated terminology was agreed on. The term 'femoroacetabular impingement syndrome' was introduced to reflect the central role of patients' symptoms in the disorder. To reach a diagnosis, patients should have appropriate symptoms, positive clinical signs and imaging findings. Suitable treatments are conservative care, rehabilitation, and arthroscopic or open surgery. Current understanding of prognosis and topics for future research were discussed. The 2016 Warwick Agreement on FAI syndrome is an international multidisciplinary agreement on the diagnosis, treatment principles and key terminology relating to FAI syndrome.Author note The Warwick Agreement on femoroacetabular impingement syndrome has been endorsed by the following 25 clinical societies: American Medical Society for Sports Medicine (AMSSM), Association of Chartered Physiotherapists in Sports and Exercise Medicine (ACPSEM), Australasian College of Sports and Exercise Physicians (ACSEP), Austian Sports Physiotherapists, British Association of Sports and Exercise Medicine (BASEM), British Association of Sport Rehabilitators and Trainers (BASRaT), Canadian Academy of Sport and Exercise Medicine (CASEM), Danish Society of Sports Physical Therapy (DSSF), European College of Sports and Exercise Physicians (ECOSEP), European Society of Sports Traumatology, Knee Surgery and Arthroscopy (ESSKA), Finnish Sports Physiotherapist Association (SUFT), German-Austrian-Swiss Society for Orthopaedic Traumatologic Sports Medicine (GOTS), International Federation of Sports Physical Therapy (IFSPT), International Society for Hip Arthroscopy (ISHA), Groupo di Interesse Specialistico dell'A.I.F.I., Norwegian Association of Sports Medicine and Physical Activity (NIMF), Norwegian Sports Physiotherapy Association (FFI), Society of Sports Therapists (SST), South African Sports Medicine Association (SASMA), Sports Medicine Australia (SMA), Sports Doctors Australia (SDrA), Sports Physiotherapy New Zealand (SPNZ), Swedish Society of Exercise and Sports Medicine (SFAIM), Swiss Society of Sports Medicine (SGMS/SGSM), Swiss Sports Physiotherapy Association (SSPA).

Bet Anywhere, Anytime: An Analysis of Internet Sports Bettors' Responses to Gambling Promotions During Sports Broadcasts by Problem Gambling Severity.

PubMed

Hing, Nerilee; Russell, Alex Myles Thomas; Lamont, Matthew; Vitartas, Peter

2017-12-01

Promotions for online sports betting during televised sports broadcasts are regularly viewed by millions of Australians, raising concerns about their impacts on vulnerable groups including at-risk and problem gamblers. This study examined whether responses to these promotions varied with problem gambling severity amongst 455 Australian Internet sports bettors participating in an online survey. Results indicated that young male Internet sports bettors are especially vulnerable to gambling problems, particularly if they hold positive attitudes to gambling sponsors who embed promotions into sports broadcasts and to the promotional techniques they use and this heightens the risk that alluring messages contribute to excessive gambling. As problem gambling severity increased, so too did recognition that these promotions have impacted negatively on their sports betting behaviour. Because a plethora of sports betting brands and promotions are now heavily integrated into sports coverage, social marketing efforts are needed to offset their persuasive appeal and counter the positive attitudes towards them that appear linked to excessive gambling amongst Internet sports bettors.

2017-01-01

In recent years there has been a rapid growth in interest in extreme sports. For the most part research has focused on understanding motivations for participation in extreme sports and very little research has attempted to investigate the psychological structure of effective performance. Those few studies that have attempted to explore this issue have tested models designed for traditional sport on adventure sports. However, extreme sports are not the same as adventure sports or traditional sports. This study employed a narrative approach to investigate experiences of effective performance in the extreme sport of proximity wingsuit flying. An overarching theme we labeled ‘leave your ego at the door,’ emerged based on four sub-themes: (1) know thy self, (2) know thy skills, (3) know the environment now, and (4) tame the ‘inner animal.’ These themes are presented and discussed in relation to performance and discovery narratives identified within elite sport, thereby shedding light on how participants’ experiences of the extreme sport of proximity wingsuit flying differ from dominant stories within traditional sports.

A major policy goal of many ministries of sport and health is increased participation in sport to promote health. A growing literature is emerging about the benefits of sport participation on happiness. A challenge in establishing a link between sport participation and happiness is controlling for endogeneity of sport participation in the happiness equation. This study seeks to establish causal evidence of a relationship between sport participation and self reported happiness using instrumental variables (IV). IV estimates based on data from a 2009 population survey living in Rheinberg, Germany indicate that individuals who participate in sport have higher life happiness. The results suggest a U-shaped relationship between age and self-reported happiness. Higher income is associated with greater self-reported happiness, males are less happy than females, and single individuals are less happy than nonsingles. Since the results are IV, this finding is interpreted as a causal relationship between sport participation and subjective well-being (SWB). This broader impact of sport participation on general happiness lends support to the policy priority of many governments to increase sport participation at all levels of the general population.

To determine whether community integration and/or quality of life (QoL) among people living with chronic spinal cord injury (SCI) are superior among sport participants vs non-sport participants. Cross-sectional study. Persons (n=90) living in the community with SCI (ASIA Impairment Scale A-D), level C5 or below, > 15 years of age, >12 months postinjury, and requiring a wheelchair for >1 hours/day were divided into 2 groups based on their self-reported sport participation at interview: sport participants (n=45) and non-sport participants (n 5). Independent-sample t tests revealed that both Community Integration Questionnaire (CIQ) and Reintegration to Normal Living Index (RNL) total mean scores were higher among sport participants vs nonsport participants (P < 0.05). Significant correlation between CIQ and RNL total scores was found for all participants (Pearson correlation coefficients, P < 0.01). Logistic regression analysis revealed that the unadjusted odds ratio of a high CIQ mean score was 4.75 (95% CI 1.7, 13.5) among current sport participants. Similarly, the unadjusted odds ratio of a high RNL score was 7.00 (95% CI 2.3, 21.0) among current sport participants. Regression-adjusted odds ratios of high CIQ and high RNL scores were 1.36 (95% CI 0.09, 1.45) and 0.15 (95% CI 0.04, 0.55), respectively. The odds ratio for pre-SCI sport participation predicting post-SCI sport participation was 3.06 (95% CI 1.23, 7.65). CIQ and QoL scores were higher among sport participants compared to non-sport participants. There was an association between mean CIQ and RNL scores for both groups. Sport participants were 4.75 and 7.00 times as likely to have high CIQ and QoL scores. Both groups had a similar likelihood of high CIQ and RNL scores after adjusting for important confounders. Individuals who participated in sports prior to SCI were more likely to participate in sports post-SCI.

The Developmental Model of Sports Participation proposes two pathways towards expertise in sports between 6 and 12 years of age: early specialization and early diversification. This study investigated the effect of sampling various sports and of spending many or few hours in sports on fitness and gross motor coordination. Altogether, 735 boys in three age groups (6-8, 8-10, and 10-12 years) were profiled using a fitness test battery. A computerized physical activity questionnaire was used to obtain data on sports participation. In the eldest group, (M)ANCOVA showed a positive effect of sampling various sports on strength, speed, endurance, and gross motor coordination (P < 0.05). A positive effect of many hours per week spent in sports was apparent in every age group. These data suggest an acute positive effect of many hours in sports and a latent positive effect of early sampling on fitness and gross motor coordination. Multiple comparisons revealed that boys aged 10-12 years, who spent many hours in various sports, performed better on standing broad jump (P < 0.05) and gross motor coordination (P < 0.05) than boys specializing in a single sport. Therefore, our results highlight the importance of spending many hours in sports and sampling various sports in the development of fitness and gross motor coordination.

Epilepsy, seizures, physical exercise, and sports: A report from the ILAE Task Force on Sports and Epilepsy.

People with epilepsy (PWEs) are often advised against participating in sports and exercise, mostly because of fear, overprotection, and ignorance about the specific benefits and risks associated with such activities. Available evidence suggests that physical exercise and active participation in sports may favorably affect seizure control, in addition to producing broader health and psychosocial benefits. This consensus paper prepared by the International League Against Epilepsy (ILAE) Task Force on Sports and Epilepsy offers general guidance concerning participation of PWEs in sport activities, and provides suggestions on the issuance of medical fitness certificates related to involvement in different sports. Sports are divided into three categories based on potential risk of injury or death should a seizure occur: group 1, sports with no significant additional risk; group 2, sports with moderate risk to PWEs, but no risk to bystanders; and group 3, sports with major risk. Factors to be considered when advising whether a PWE can participate in specific activities include the type of sport, the probability of a seizure occurring, the type and severity of the seizures, seizure precipitating factors, the usual timing of seizure occurrence, and the person's attitude in accepting some level of risk. The Task Force on Sports and Epilepsy considers this document as a work in progress to be updated as additional data become available.

To assess the relationship between proximity to specific sports facilities and participation in the corresponding sports activities for adolescents in Germany. A sample of 1,768 adolescents aged 11-17 years old and living in 161 German communities was examined. Distances to the nearest sports facilities were calculated as an indicator of proximity to sports facilities using Geographic Information Systems (GIS). Participation in specific leisure-time sports activities in sports clubs was assessed using a self-report questionnaire and individual-level socio-demographic variables were derived from a parent questionnaire. Community-level socio-demographics as covariates were selected from the INKAR database, in particular from indicators and maps on land development. Logistic regression analyses were conducted to examine associations between proximity to the nearest sports facilities and participation in the corresponding sports activities. The logistic regression analyses showed that girls residing longer distances from the nearest gym were less likely to engage in indoor sports activities; a significant interaction between distances to gyms and level of urbanization was identified. Decomposition of the interaction term showed that for adolescent girls living in rural areas participation in indoor sports activities was positively associated with gym proximity. Proximity to tennis courts and indoor pools was not associated with participation in tennis or water sports, respectively. Improved proximity to gyms is likely to be more important for female adolescents living in rural areas.

To examine which school sports engage children in more physical activity. Observational, cross-sectional study examining differences between intramural (IM) and interscholastic (IS) sports. Athletic facilities at two schools with IM sports and two schools with IS sports in Wake County, North Carolina. Middle-school children (N = 6735). Percentage of children observed in sedentary, moderate, and vigorous activity assessed by the System for Observation Play and Leisure Among Youth (SOPLAY). Energy expenditure and physical activity intensity were also estimated by using MET values. T-tests; generalized linear model using cumulative logit link function. IM sports had higher MET values than IS sports (t = -3.69, p < .001), and IM sports ranked in four of the top five sports in terms of average MET values. Regression models found a significant interaction between school sport delivery model and gender, with boys significantly less physically active in IS programs than boys in IM programs (B = -.447, p < .001) but more physically active (B = .359, p <.001) than girls in IM sports. Regardless of sport type, IM sports generated more physical activity than IS sports among boys but not girls. Soccer, basketball, and track, regardless of school delivery approach, provide the highest physical activity levels. Results suggest that school administrators consider reassessing their programs to more efficiently use diminishing resources to increase students' physical activity levels.

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.

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.

Much evidence indicates that men experienced an evolutionary history of physical competition, both one-on-one and in coalitions. We thus hypothesized that, compared to girls and women, boys and men will possess a greater motivational predisposition to be interested in sports, especially team sports. According to most scholars, advocacy groups, and the United States courts, however, this hypothesis is challenged by modest sex differences in organized school sports participation in the contemporary U.S., where females comprise 42% of high school participants and 43% of intercollegiate participants. We conducted three studies to test whether organized school sports participation data underestimate the actual sex difference in sports participation. Study 1 analyzed the American Time Use Survey, which interviewed 112,000 individuals regarding their activities during one day. Females accounted for 51% of exercise (i.e., non-competitive) participations, 24% of total sports participations, and 20% of team sports participations. These sex differences were similar for older and younger age groups. Study 2 was based on systematic observations of sports and exercise at 41 public parks in four states. Females accounted for 37% of exercise participations, 19% of individual sports participations, and 10% of team sports participations. Study 3 involved surveying colleges and universities about intramural sports, which primarily consist of undergraduate participation in team sports. Across 34 institutions, females accounted for 26% of registrations. Nine institutions provided historical data, and these did not indicate that the sex difference is diminishing. Therefore, although efforts to ensure more equitable access to sports in the U.S. (i.e., Title IX) have produced many benefits, patterns of sports participation do not challenge the hypothesis of a large sex difference in interest and participation in physical competition.

Sport talent identification and development (TI and TD) in youth continues to attract strong interest among coaches, sport scientists and sport administrators. TI for sport in youth with the anticipation of future elite level sport achievement is both an art and a science, and is strongly influenced by within athlete and extraneous-to-athlete factors (ecosystem of support or the lack of). The returns from investment on current TI and TD models of sport in youth are subpar in that few continue in the sport to achieve podium positions at the elite sport level in adulthood. Why, where and how one succeeds in sport, and what that success means to the athlete and stakeholders are dependent on the culture and context of the country. We advocate harnessing the power of sport to help in youth development, to be holistic in its nurturance, to allow for individual idiosyncratic expressions of the athletes, to provide for talent transfer across sport, and to facilitate key stakeholders to 'join' hands to work for the common interest and understanding for as many youth and adults so as to provide them with opportunities through support and coaching to compete at the different levels of competition in sport. Governments, policy makers and administrators of sport must decide, within their specific circumstances, if TI and TD in sport in youth is serving a meaningful purpose and is a viable return on investment; in short, is it mission possible or is it… a quest for the Holy Grail for a podium finish in elite level sport competition?

To investigate the longitudinal effect of sport participation in physical activity, fitness and body fat changes during childhood and adolescence. Longitudinal study (134 boys, 155 girls) of Australian youth aged 8-16 years. Physical activity was assessed by pedometers and accelerometers, fitness by the 20m shuttle-run, body fat by DEXA and club sport participation by questionnaire. Linear mixed models were used to determine the effects of sport participation and gender differences. Sports club participants were more physically active at all age groups than non-participants; boys took an extra 1800 steps (p<0.001) and girls 590 steps per day (p<0.01) and boys engaged in an extra 9min and girls 6min more moderate to vigorous PA per day (both p<0.05). Fitness was higher among sports participants (boys 27% and girls 20% higher, both p<0.001) and sport participant girls had 2.9% less body fat (p<0.05). Higher fitness scores were maintained over time by sports participants but their greater PA diminished during adolescence, this being more evident among girls. Only 20% of sports club participants met the recommended daily average of 60min MVPA. Sport participants were more active, fitter and had less body fat (girls only) than non-sports participants. However, the associated benefits of sport with PA diminished during adolescence and the majority of sports participants did not meet recommended levels of PA. Strategies aiming to maximise the benefits of sports participation may be enhanced by providing special attention to the early adolescent period particularly among girls.

Much evidence indicates that men experienced an evolutionary history of physical competition, both one-on-one and in coalitions. We thus hypothesized that, compared to girls and women, boys and men will possess a greater motivational predisposition to be interested in sports, especially team sports. According to most scholars, advocacy groups, and the United States courts, however, this hypothesis is challenged by modest sex differences in organized school sports participation in the contemporary U.S., where females comprise 42% of high school participants and 43% of intercollegiate participants. We conducted three studies to test whether organized school sports participation data underestimate the actual sex difference in sports participation. Study 1 analyzed the American Time Use Survey, which interviewed 112,000 individuals regarding their activities during one day. Females accounted for 51% of exercise (i.e., non-competitive) participations, 24% of total sports participations, and 20% of team sports participations. These sex differences were similar for older and younger age groups. Study 2 was based on systematic observations of sports and exercise at 41 public parks in four states. Females accounted for 37% of exercise participations, 19% of individual sports participations, and 10% of team sports participations. Study 3 involved surveying colleges and universities about intramural sports, which primarily consist of undergraduate participation in team sports. Across 34 institutions, females accounted for 26% of registrations. Nine institutions provided historical data, and these did not indicate that the sex difference is diminishing. Therefore, although efforts to ensure more equitable access to sports in the U.S. (i.e., Title IX) have produced many benefits, patterns of sports participation do not challenge the hypothesis of a large sex difference in interest and participation in physical competition.

Regular exercise reduces cardiovascular and overall mortality. Participation in sports is an important determinant of cardiovascular health and fitness. Regular sports activity is associated with a smaller risk of sudden cardiac death (SCD). However, there is a small risk of sports-related SCD. Sports-related SCD accounts for approximately 5% of total SCD. SCD among athletes comprises only a fraction of all sports-related SCD. Sport-related SCD has a male predominance and an average age of affliction of 45 to 50 years. Survival is better than for other SCD. This review summarizes links between sports and SCD and discusses current knowledge and controversies. Copyright © 2017 Elsevier Inc. All rights reserved.

Sports-related concussions — media, science and policy

Although growing awareness about the potential long-term deleterious effects of sport-related concussion has led to increased attention to the risks of collision sports, calls to ban these sports, such as American football, might be premature. Collision sports have a relatively high incidence of concussions, but participation in these sports also confers a host of benefits. In addition, the associated risks of participation, including concussion, have not been definitively shown to outweigh the benefits they provide, and the risk–benefit ratio might vary among individuals. The risks of concussion and repetitive concussions associated with collision sports are unknown in the general population and not well characterized even in elite athlete populations. In this article, we discuss current knowledge on sports-related concussion, its neurological consequences, and implications for regulation of the practice of collision sports. PMID:27364748
