The analysis and clarification of man's physical properties are very important in the field of sport and welfare engineering. The results of these analysis and clarification contribute to the improvement of physical ability, the prevention of injury in sports, the effective rehabilitation and the evaluation of dynamic load in daily life. The solid body link model, which has been used for the analysis on human body performance, can estimate the force and torque which acts on each joint from the recorded human motion. However, the muscle functionality is not considered in the solid body link model. In order to evaluate the muscular power during human motion, the human musculo-skeletal model considering bi-articular muscle function is required. In this study, the basic two dimensional musculo-skeletal model of man's lower limb was constructed and the muscular power of each effective muscle was estimated from the recorded human motion. The lower limbs muscular power in vertical jump is estimated to verify the musculo-skeltal model constructed.
