Now, an exercise has attention because of an increase in health conscious. But the more exercising population increase, the more number of injured increase. These injured are required for rehabilitation. Then, by departing from an exercise, rehabilitation for athlete is prolonged. So applying a competitive exercise to the rehabilitation, it is expected that injured athlete would return to the competitive field in a short term. The purpose of this study is the development of device that can be prevented reducing the muscle, the joint range of motion and the sense in action athletics by using reproduction of the action of running. The rehabilitation device is designed by using a planar 4-link mechanism and to reproduce the movement of the human leg in the action of the running by the movement of the link. Furthermore, considering the load, by applying force to the foot using springs installed in the planar 4-link mechanism for the muscle rehabilitation, it is investigated that the device would reproduce the reaction force while kicking the ground.
