BIOMECHANICS OF STANDING LONG JUMP WITH HADNHELD WEIGHT

INTRODUCTION: Many studies had proved that extra weights was held in the hands of the athletes during the long jump competition(Minetti &Ardigo 2002; Lenoir, Clercq & Laporte, 2005), and some researchers found that extra weights would increase the jump distance, but those studies did not point out the joint moment and power. The purpose of this study was to investigate the biomechanical difference between unloaded and loaded groups, and to understand the joint moment and power of standing long jump
