The use of technological aids to improve sport performance ('techno doping') and inclusion of Paralympic athletes in Olympic events are matters of ongoing debate. Recently, a long jumper with a below the knee amputation (BKA) achieved jump distances similar to world-class athletes without amputations, using a carbon fibre running-specific prosthesis (RSP). We show that athletes with BKA utilize a different, more effective take-off technique in the long jump, which provided the best athlete with BKA a performance advantage of at least 0...

This study tested the hypothesis that adrenocortical function would be altered in horses with equine gastric ulcer syndrome (EGUS). Twenty-six sport horses competing at national or international levels in eventing (n=15) or endurance (n=11) were subjected to a gastroscopic examination and an adrenocorticotropic hormone (ACTH) stimulation test. Salivary cortisol concentrations were measured before (baseline) and after (30, 60, 90, 120 and 150min) IV ACTH injection (1μg/kg bodyweight). Within EGUS, two distinct diseases, equine squamous gastric disease (ESGD) and equine glandular gastric disease (EGGD), can be distinguished...

To date, much research has been devoted to understanding how anxiety can affect sport performance, both in practice and in competitive settings. It is well known that sport has the potential for high levels of stress and anxiety, and that practicing and employing a range of psychological strategies can be beneficial in anxiety management. Equally, growing evidence also suggests that anxiety can play a role in sport injury prevention, occurrence, rehabilitation, and the return to sport process. The purpose of this paper is to provide current insights into sport-related anxiety...

Adele Meron, Deborah Saint-Phard
Throwing events in track and field are among the oldest sporting events in recorded history and include shot put, discus, hammer, and javelin. All throwing athletes use the kinetic chain to transfer energy from the lower extremities, through the pelvis, trunk, shoulder, arm, wrist, hand, and finally into the implement to generate maximum force. Throughout this sequential activation, mobilization, and stabilization of body segments, there is opportunity for breakdown in the chain, which can lead to injury. This review describes the biomechanics and kinetic chain components of each event and highlights injuries common among all throwers as well as injuries unique to each event...

E Ortega, C J K Wang
Heart rate variability (HRV) is commonly used in sport science for monitoring the physiology of athletes but not as an indicator of physiological state from a psychological perspective. Since HRV is established to be an indicator of emotional responding, it could be an objective means of quantifying an athlete's subjective physiological state before competition. A total of 61 sport shooters participated in this study, of which 21 were novice shooters, 19 were intermediate shooters, and 21 were advanced level shooters...

OBJECTIVES: Sport practice is a key factor in a person's physical and mental health but, for adolescent athletes, some injuries lead to health problems in the long term. The literature provides multiple factors for understanding injury but does not give information about injury risk related to each level of play in a large sample of multisport athletes. This study investigates this relationship in 14- to 19-year-old adolescents. METHODS: The survey on adolescents and health was conducted in classrooms of France, from February to March 2015...

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...

Adolescents were asked to nominate peers who experience appearance-related victimization or engage in appearance-related aggression, in order to examine the peer social status and competency correlates of receiving more nominations. Moreover, the correlates of peer-report vs. self-report appearance-related victimization were considered. Participants were 371 young Australian adolescents (55% girls, Mage = 12.0 years) who completed surveys. Results showed that victimized adolescents were rated as less liked, prosocial, popular and good-looking, and perceived themselves to be less attractive, less competent at sport and more teased by peers about appearance...

We are writing this piece in the aftermath of the 2016 Olympic Games in Rio de Janeiro, Brazil. Each of the words in the title plays a role(s) in deciding who may compete, especially who may compete as a woman. We shall be careful to disentangle the issues of genes and gender from hormonal levels of the potent androgen testosterone, and very clearly demarcate these natural occurrences from those of doping, for which the World Anti-Doping Agency has established strict guidelines. These elements became conflated in the aftermath of the Court of Arbitration of Sport's decision, now more than 2 years ago, concerning the teenage Indian sprinter, Dutee Chand...

The Hungarian National Institute for Sports Medicine (NISM) was founded in 1952 to provide medical coverage for national teams, screening and periodic health evaluation (PHE) for all Hungarian athletes. The system of 'all in one and ASAP' evolved by now to a specific state-funded healthcare provider with complex sports medical and sport-related services available for athletes. The NISM created a countrywide network to make health clearance available for all athletes close to their place of residency. This centralised system guarantees the uniformity and financial independence of the network, as it is directly financed by the government and free for every competitive athlete...

Learning the basic competencies of critical thinking are very important in the education of any young scientist, and teachers must be prepared to help students develop a valuable set of analytic tools. In my experience, this is best achieved by encouraging students to study areas with little scientific consensus, such as the control mechanisms of the exercise ventilatory response, as it can allow greater objectivity when evaluating evidence, while also giving students the freedom to think independently and problem solve...
