Dynamic contribution of joint torques to the generation of swing leg motion in sprint

(Dynamische Anteilsanalyse der Gelenkmomente bei der Generierung Beinschwungbewegungen im Sprint)

The purposes of this study were 1) to investigate the contribution of individual terms such as the swing leg joint torques, motion-dependent term (MDT) and other terms to the generation of the knee joint angular velocity, and 2) to quantify the functional roles of the joint torques in the swing leg motion with consideration of the generating factor of the MDT. The swing leg was modeled as a linked system of three rigid segments in sagittal plane. Dynamic contributions and generating factors of the MDT were calculated using the equation of motion for the swing leg model. The results obtained in this study indicate that 1) the MDT was one of the great contributors to the generation of the knee joint angular velocity, and 2) the main generating factors of the MDT were the swing leg joint torques.
