Abstract

INTRODUCTION: Plyometric exercises are a series of cyclical activities of muscle stretch and shortening. Jumping and landing are the major movements of plyometric exercises. Previous researches reported that the plyometric training can increase the proprioception in lower extremities. It also reported that plyometric jump exercise has great assistance to increase muscle strength of lower limbs. However, a few of published researches had studied the joint loading of lower limbs in each movement of plyimetric jump. Understanding of the loading on the lower limbs is greatly helpful to decide the proper exercise prescription for the subjects who had suffered musculoskeletal injury and in the period of rehabilitation. The purpose of this study is to estimate the joint kinetics of lower limbs in depth jump.
