Apollo 13 was initially looking like it would be the smoothest flight ever. After the explosion of an oxygen tank however, the astronauts were close to spending the rest of their lives in rotation around the planet. I wished to use this well-known incident to discuss further the link, or lack thereof, between sport sciences research and current field practices. There is a feeling that the academic culture and its publishing requirements have created a bit of an Apollo 13-like orbiting world (e.g., journals and conferences) that is mostly disconnected from the reality of elite performance...

The purpose of this study was to assess the relationship between motivation, engagement and personal and social responsibility among athletes. Based on the literature, a survey was conducted including measures of motivation, considering task orientation and ego orientation, intrinsic and extrinsic motivation, and amotivation. We also measured the components of engagement (dedication, confidence, vigor and enthusiasm) and the components of personal and social responsibility. A total of 517 athletes from different types of sports participated in the study...

Master clinicians and successful long-distance runners have a lot in common. Both are dedicated to continuous improvement and are flexible in their approach, allowing for adaptation to meet unplanned challenges. Given these similarities and the important role of coaches in athletics, there is an opportunity for medical educators to learn from excellent running coaching. The authors spent time with three respected running coaches at different levels (high school, college, and postcollegiate online) and identified six principles employed by these coaches that seem to be particularly relevant for promoting skill development in medicine...

Outdoor sports teams may be exposed to acute cold stress during competition, which may affect performance. Limited research has explored the effects of cold exposure on athletic components. The purpose of this study was to examine the effects of an acute whole-body cool exposure on pro-agility, vertical jump, and sprint performances. Eleven lightly clothed (∼0.3 clo) and not cold acclimatized volunteers (10/1 women/men: age 20.5 ± 0.5 y; height 1.65 ± 0.09 m; mass 63.3 ± 8.9 kg; body fat 21.3 ± 7.6%) completed performance tests in both thermoneutral (17...

Sled towing is a common form of overload training in sports to develop muscular strength for sprinting. This type of training leads to acute and chronic outcomes. Acute training potentially leads to postactivation potentiation (PAP), which is when subsequent muscle performance is enhanced following a preload stimulus. The purpose of this study was to determine differences between rest intervals following sled towing on acute sprint speed. Twenty healthy recreationally trained males (age= 22.3 ± 2.4yrs, height= 176...

We investigated muscle activity, oxygen uptake, heart rate, and rating of perceived exertion during running in water and on dry land at submaximal and maximal efforts. Eleven recreational runners performed deep water running (DWR) and treadmill running (TMR) graded exercise tests on separate days. On the third test day, the participants exercised at their 60%, 80%, and 100% of maximal oxygen uptake (VO2max) by matching specific stride frequencies or running speeds. VO2max, maximal heart rate (HRmax), and rating of perceived exertion at maximal effort (RPEmax) were measured...

BACKGROUND: Dropout from organized youth sport has significant adverse health implications. Enjoyment and behavioral intentions have consistently been linked with participation and dropout; however few studies have investigated these links using a prospective design. This study explored whether enjoyment and intentions to continue predicted dropout behavior at one-year follow-up. METHODS: Questionnaires were completed by 327 regular sports participants (Mage=13...

BACKGROUND: Shoulder pain is becoming increasingly problematic in young players as volleyball gains popularity. Associations between repetitive motion and pain and overuse injury have been observed in other overhand sports (most notably baseball). Studies of adult athletes suggest that there is a shoulder pain and overuse problem present in volleyball players, but minimal research has been done to establish rates and causes in juvenile participants. PURPOSE: To establish rates of shoulder pain, regardless of whether it resulted in a loss of playing time, in female high school volleyball players...

Taking performance-enhancing drugs (PEDs) can cause serious and irreversible health consequences, which can ultimately lead to premature death. Some young people may take PEDs without fully understanding the ramifications of their actions or based on the advice from others. The purpose of this systematic review was to identify the main factors that predicted doping among young people. The literature was systematically reviewed using search engines, manually searching specialist journals, and pearl growing. Fifty-two studies, which included 187,288 young people aged between 10 and 21 years of age, 883 parents of adolescent athletes, and 11 adult coaches, who were interviewed regarding young athletes, were included in this review...

Participation in competitive sport may impact psychological measures, such as mood and performance anxiety, which in turn may impact enjoyment, adherence, continued participation, and so on. This study assessed the feasibility - in terms of process, resources, management, and potential scientific value- of measuring the effect of varying competitive challenges upon the mood and performance anxiety measures of high school athletes. The participants (n=12) consisted of the boys' varsity basketball team at a high school in a rural Midwestern community...

Tim Weesner
Skin infections are a common ailment that affect all students, with increased risk to those students participating in sport and specifically contact sports. The types of skin infections that students are likely to encounter are categorized into three types: (a) bacterial, (b) viral, and (c) fungal. All three types of infection can appear benign at onset but can grow into serious disease and illness if not correctly identified and treated in a timely manner. A strong prevention program should be in place at all schools with appropriate resources in place (human and financial) to carry out proper cleaning of facilities, on-site examination by the school nurse or athletic trainer, and sufficient education of coaches, athletes, parents and administrators...

Vertical jump height (VJ) is one of the most sensitive measures to quantify training-related fatigue and athletic performance in elite athletes. Currently, however, there is no equipment designed to graphically deliver the daily performance changes in VJ compared with the smallest worthwhile change (SWC), which is considered essential in "progressive statistics" to judge meaningful performance fluctuations. The aims of the study were to analyze the criterion validity of a new contact mat (i.e., Elite Jump®), alongside testing its usability to detect meaningful changes in VJ of elite team sport athletes...

We investigated cardiac autonomic responses and hemodynamic parameters on recovery time following short-, middle- and long-swimming performance. Ten male regional-level swimmers were tested to estimate time and frequency domains of arterial baroreflex sensitivity and heart rate variability after 100-, 200-, and 400-m of front crawl. We found a BRS reduction for 90 min after a maximal 100- and 200-m front crawl event, meanwhile the reflex was restored back to the baseline value about 70 min after 400-m. The vagally mediated HF power of R-R intervals was significantly reduced for 30 min after 400-m, and more than 90 min after 100- and 200-m, with a concomitant increase of sympathetic modulation...

This systematic review investigates the acute effects of physical or psychosocial interventions on testosterone and cortisol responses in elite male rugby union players, and the subsequent association with physical performance areas (e.g. strength, power, sprint performance) or key performance indicators (e.g. coach-identified skills). Medline (via EBSCO), SPORTDiscus, Web of Science, Informit, Proquest, Cochrane and Scopus were searched for relevant articles. Nine articles met the inclusion criteria, with six articles examining the effect of speed, strength or power training, and the remaining three psychosocial interventions...

BACKGROUND: Awareness of sport-related concussion (SRC) is an essential step in increasing the number of athletes or parents who report on SRC. This awareness is important, as there is no established data on medical care at youth-level sports and may be limited to individuals with only first aid training. In this circumstance, aside from the coach, it is the players and their parents who need to be aware of possible signs and symptoms. The aim of this study was to examine the psychometric properties of a parent and player concussion survey intended for use before and after an education campaign regarding SRC...

This commentary on Hardy and colleagues' discussion of psychosocial biographies of British super-elite athletes discusses cultural differences from a Chinese perspective. While British super-elite athletes might cope with high pressure by a counter-phobic attitude or total preparation, Chinese super-elite athletes achieve that by "Pingchangxin," a concept originated from Hongzhou Buddhism. This concept is difficult to translate but includes having no evaluation of good and evil, maintaining a peaceful mind in adversity and frustration, letting nature take its course, so as to reach the realm of freedom...

Participants were 32 former GB athletes from Olympic sports, 16 Super-Elite athletes who had won multiple medals at major championships, and 16 matched Elite athletes who had not. In-depth interviews with the athletes, their coaches, and one of their parents explored all psychosocial aspects of their development and careers. Content analyses revealed that there were no differences between Super-Elite and Elite athletes with regard to family values, conscientiousness, or commitment to training. However, the two groups were found to be different with regard to: (1) the experience of a foundational negative life event coupled with a foundational positive sport-related event; (2) the experience of a career turning point that enhanced motivation and focus for their sport; (3) need for success; (4) obsessiveness and/or perfectionism with regard to training and performance; (5) ruthlessness and/or selfishness in the pursuit of their sporting goals; (6) dual focus on both mastery and outcome; (7) the use of counterphobic attitudes and/or total preparation to maintain higher levels of performance under pressure; and (8) the relative importance of sport over other aspects of life...
