Abstract
A resistance training device effectively training the muscular force of a desired muscle includes a saddle for a user to sit on, a robot arm adjustable to the length of a limb of the user, a fastener for securing the robot arm to the limb, a controller for controlling the torque of a driving source driving a joint of the robot arm, and an input operating unit for the user to input a driving condition. When the user inputs a training load and an output direction of the distal end of the limb to be trained, the value of a torque necessary for generating the training load is calculated. The robot arm generates the torque of the calculated magnitude acting in a direction opposite to the output direction in such a manner that a constant training load is exerted to the user without dependency on the position of the user.
