Abstract
Strengthening muscle force by training, e.g., isokinetic exercises, is effective for not only healthy persons but also those who need rehabilitation. The isokinetic exercise is a training method under the restriction of constant rotational speed of target joint of human during exercise. In this paper, we describe design method of the isokinetic exercise machine using MR brake that has great performance of high speed and high torque. At the same time, we describe the result of isokinetic exercise training using the developed machine. This machine can realize safety training and good controllability of angular velocity of the joint only with the brake.
