Basketball is a physically demanding team sport characterized by frequent high-intensity phases 1 during which neuromuscular factors are heavily taxed. 2 Players are frequently asked to quickly accelerate, decelerate, and change direction during basketball games. 1 Specifically, time

independent lower-limb power qualities in soccer players. 3 However, no attempt has been made to investigate the neuromuscular factors underpinning direction-specific (soccer associated) CMJ performance. Such information could be used to inform the neuromuscular factors that should be considered when

, challenges, tackles, and changes of direction. 1 – 3 Intermittent high-intensity training consisting of straight-line (STL) or change-of-direction (COD) running is largely used by coaches to improve aerobic fitness and the ability to accelerate and change direction. 3 – 5 Previous findings 3 , 5 suggest

. Basketball players often execute sprints while changing directions rapidly. 1 , 10 Therefore, repeated-change-of-direction (RCOD) speed plays an essential role in basketball 1 as players are required to sprint maximally, rapidly decelerate, then reaccelerate frequently. Given changes in direction alter

The physical abilities associated with accelerations, decelerations, and rapid changes of direction (CODs) are considered key components in the game demands of many team sports. 1 For example, a recent systematic review showed that there are 500 to 3000 changes of activity over the course of a

Soccer is a sport characterized by an intermittent exercise profile where numerous intense and brief actions are alternated with submaximal work bouts during match games and training sessions. 1 Indeed high-speed displacements with repeated turns, twists, and explosive change-of-direction (COD

The present article addresses some of the critical issues that are involved in the development of a successful career in applied sport psychology by offering a three-phase model of career direction, development, and opportunities. In particular, educational direction and training, supplemental experience, and sport, exercise, or health involvement are considered. Specific concerns related to these areas are discussed relative to the enhancement of career development and opportunities.

The evaluation of change-of-direction (COD) performance is strongly focused on the time spent to perform the test trials, while much less is known about the technical execution adopted during the COD movements. Thus, the purposes of this study were to evaluate (1) the relationship between straight- and COD-sprint tests and (2) the technical execution of COD movements in relation to different age categories of young rugby players. Young rugby players (N = 157, age range 8–19 y) completed a test battery composed of a 15-m straight-sprint test (15SS) and a 15-m sprint test performed with 2 changes of direction (15COD). Significant differences were detected between age categories for both tests. Significant correlations were found between 15SS and 15COD. The analysis of the technical execution of the 15COD test showed differences between age categories, with a prevalence of rounded turns up to the U15 category. These findings confirmed the relationship between straight and COD abilities in young male rugby players. Moreover, the new approach introduced by this study, based on the analysis of COD technical execution, revealed that this performance could be conditioned by the age and mastery level of the players.
