The research was designed to examine the relationship between the development of muscle fatigue and the effect it has on sport performance, specifically during maximal voluntary contraction. This kind of this investigation using simultaneous electrophysiological and mechanical recordings, based on advanced mathematical processing, allows us to get parameters, and indexes in a short time, and fi...

The general consensus among sport and exercise genetics researchers is that genetic tests have no role to play in talent identification or the individualised prescription of training to maximise performance. Despite the lack of evidence, recent years have witnessed the rise of an emerging market of direct-to-consumer marketing (DTC) tests that claim to be able to identify children's athletic ta...

Elite sports performance fundamentally relies on a complex set of brain functions engaged once visual signals are relayed from the eye. In this review, we overview a series of these neural mechanisms-focusing specifically on the critical role of attention in sculpting the visual processing that takes place leading up to a decision. These brain functions are introduced within the theoretical con...

In Study 1, a sample of tennis players ranked at the national level (n = 173) completed a French version of the Situational Motivation Scale the day before a tennis competition. Results revealed the presence of a three-cluster solution. Differences among clusters on subsequent sport performance were significant. Specifically, athletes with the least self-determined motivational profile obtained...

Determination of pedal forces is a prerequisite to analyse cycling performance capability from a biomechanical point of view. Comparing existing pedal force measurement systems, there are methodological or practical limitations regarding the requirements of scientific sports performance research and enhancement. Therefore, the aim of this study was to develop and to validate a new bicycle instr...

The jump squat is one of the exercises most frequently used to improve lower body power production, which influences sports performance. However, the traditional determination of the specific workload at which power production is maximized (i.e., optimum power load) is time-consuming and requires one-repetition maximum tests. Therefore, the aim of this study was to verify whether elite athletes...

BACKGROUND The ability to determine athletic performance in varsity athletes using preseason measures has been established. The ability of pre-season performance measures and athlete's exposure to predict the incidence of injuries is unclear. Thus our purpose was to determine the ability of pre-season measures of athletic performance to predict time to injury in varsity athletes. METHODS Male...

A literature search and narrative review was carried out with the intent of determining the current level of knowledge regarding the chiropractic treatment of athletes for the purpose of sport performance enhancement. Of the fifty-nine relevant articles retrieved, only 7 articles of variable quality were obtained which specifically investigated/discussed chiropractic treatment and its involveme...

Assessment of sport performance is based on mechanical analysis of a movement. In high jump there are two main sequences: a run-up and a jump. The efficiency of a high jump can be described taking into account location of a centre of mass of a jumper while acquiring a standing up-right position and then at the highest position over a bar during a jump. The difference of those locations is taken...

BACKGROUND Physical activity in older people is believed to slow down the natural aging process through its effects on disuse atrophy. OBJECTIVES To show that elite master (age above 50) male and female athletes, as a group, have improved their running times over the last two decades at a greater rate than their younger counterparts. METHODS Running time, age, and sex of all 415,000 runners...
