JOINT POWER AND ITS RELATIONSHIP TO THE FATIGUE OF HUMAN BODY

In this study, the joint power and its relationship to levels of fatigue in the human body during vertical jumps was examined. The jumping movements, which were performed before and after a 30-second period of pedaling on a Monark bicycle ergometer, were video recorded. The video materials were then analyzed on a motion analysis system. The ground reaction force during jump was measured by a force platform. The joint power was calculated using the data from the above systems. The two groups of data were compared. The variation of joint power at each joint was computed and a quantitative description of the resulting fatigue was obtained
