In recent years, elderly persons who are needed a care are increasing. This main reasons are "disease of joints" or "bone fracture・fall down". In order to prevent these, it is necessary to training effectively muscles of the lower limbs. There for, it is important to clearly "the motion performance of joints" and "the intensity of the motion in muscles". In this paper, for the extension and flexion motion of knee joint, we quantified the motion performance of joints by using the driving power. And we quantified the intensity of the motion in muscles by using the angular momentum. Also, the 3D musculoskeletal model of lower limbs used for the analysis. And, Hill type model is used to muscle model. As those results, we could quantitatively consider "the motion performance of joints" and "the intensity of the motion in muscles".
