KINETIC PARAMETERS DETERMINANTS OF PERFORMANCE IN COUNTER MOVEMENT JUMP

Abstract

The aims of this study were: to identify the force and velocity parameters related with performance in the Counter Movement Jump (CMJ); and to compare these parameters between sprinters and volleyball players. Twelve sprinters and 12 volleyball players took part of this study. The jump height, power output, peak velocity (PV), maximum force (MF), rate of force development and time to reach maximum force were analyzed. A significant correlation of jump height with PV and between power output and all variables were found, except between jump height and MF. Difference between sprinters and volleyball players were found - p<0.05. Thus, the velocity was the main factor determinant of jump height and the maximum force and velocity were the main determinants of the power output. Sprinters had better performance in the CMJ than volleyball players.
