Abstract

Recently, the effects of concentric and eccentric training have been evaluated to determine how to make exercise more effective. Some researchers have reported that concentric exercise increases the concentric strength. In this case, concentric exercise may enhance the concentric force performance with or without lower muscle damage and pain. Therefore, we developed a concentric training machine for lower extremities that we call iSAAC. This machine has an electromagnetic brake to generate a safe resistance load for exercise. The magnitude of the resistance power is less than or equal to the human-applied power. We calculated whole body dynamics such as the joint torque and work of the lower extremities based on the inverse dynamics of the whole body without constraints. We verified the effectiveness of the system through squat-like knee extension exercise and inverse dynamics analysis. The proposed machine provided safe training for concentric knee extension and information on the whole body dynamics during exercise.
