Abstract

The purpose of this study was to identify the relationships between exercise-load duration and the kinetic characteristics of vertical jumps. Twenty-two male students majoring in physical education acted as volunteers. In this study, prolonged duration of exercise with the same amount of load was analyzed. Component forces and impulses were increased in the right, left, up, down, forward and backward directions. The torque produced in these directions increased with the prolonged duration of exercise. Therefore, a faster and more efficient method of judging sport fatigue and its degree could be accomplished by the post-exercise kinetic index—component force, impulse and torque.
