Abstract
The purpose of this study was to clarify dynamical characteristic of Javelin throw by using a forward dynamical analysis method based on the equation of motion of the whole body. The human body and Javelin were modeled as a system consisting of 16 rigid segments connected with joints, and the equation of motion was derived in consideration of degree of freedom at each joint. By using the whole body equation of motion, we calculated dynamical contributions to Javelin speed. The contributions were consisted of three parts, such as; total joint torque term; motion dependent torque term; and gravitational term. And then, the contribution of total joint torque was divided into contributions of joint axial torques. From the results, Javelin speed was mainly generated by joint torques. In all subjects, shoulder internal/external rotation torque, elbow flexion/extension torque and shoulder horizontal abduction/adduction torque showed large contribution to Javelin speed, but these ratios were different between subjects.
