performing runs with change of direction (change of direction economy) has been recommended as a viable method to better evaluate players’ energetic efficiency under more soccer-specific running patterns. 6 Specifically, change of direction economy over runs involving 180° directional changes is newly

-motion analysis of matches revealed that male players change activity on average every 1 to 3 s performing more than 1000 movements per game. 1 As several studies reported the change of direction (COD) ability to be a main determinant for successful participation in basketball, numerous tests have been developed

Change of direction speed (CODS) is an important component of performance in team-based invasion sports, such as football. 1 – 3 For this reason, understanding the determinants of change of direction (COD) ability is an important consideration for coaches. Young et al 4 proposed linear speed and

significant relationship ( r  = −.83; P  < .05) between change of direction speed (CODS) and winning percentage in Indian state-level players. As such, the acute augmentation CODS is likely to be advantageous to performance. Zois et al 7 demonstrated that a heavy (5-repetition maximum) leg press stimulus

In order to change direction while running, it is necessary to rotate the body and deflect the trajectory of the center of mass (COM) toward the new direction of travel. Cutting maneuvers, in which this change of direction takes place rapidly and over only a small number of steps, are ubiquitous in

. 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

game would contribute to decrements in running performance, which, together with changes in technical and tactical skills, could impact overall game performance. Movement economy is “activity-specific,” hence a change-of-direction economy test which assesses movement economy during team-sport crucial

, 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

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
