Abstract: It is generally believed that more muscle mass in the lower body reflects more muscular strength and power. If true, greater ground reaction forces may be facilitated from increasing muscle mass, which may result in higher maximal running speeds. One method to assess the potential contributions of body composition (i.e. muscle mass and fat …

Abstract: It has been well established that plyometric and speed training have positive impacts on fitness parameters in soccer players. The aim of this study was to compare short-term effects of a combined plyometric and speed training implemented on the same or separate days of a week on change of direction (COD), linear speed (LS), …

Abstract: The effects of different sprint training modalities on body composition are not yet known, and the effectiveness of using motorized treadmills for sprint training is yet to be assessed accurately. The following study investigated the effects of motorized treadmill and overground training on sprint performance and body composition. Sixty-four young adults (33 men and …

Abstract: Resisted sprinting (RS) is a popular training method used to enhance sprinting performance in youth. However, research has only explored the effects of forward RS (FRS) training. We examined the effects of FRS and backward RS (BRS) and compared these with a traditional physical education curriculum (CON). One hundred fifteen boys (age 13–15 years) …

Abstract – Purpose: Footedness as a predictor of brain hemispheric dominance cause performance differences in movement and sports performance. This study aimed to investigate the 30 m sprint speed difference between unilateral and bilateral foot dominance in 156 male and 37 female athletes. Material Method: It was assumed that all participants exerted maximum effort during …

The aim of this research was to determine which kinematic parameters generate the maximum sprint speed of the world’s fastest sprinter, Usain Bolt. The biomechanical parameters of a double sprint step, using a 2D kinematic analysis under conditions of the realization of its maximum velocity were analyzed. The APAS computer system was used for the …
