Ubungsgerät und Verfahren

摘要

An exercise apparatus having a vertically movable weight, and an input pedal mechanism engaged by the user to input an input power with a unidirectional exercise force at a user-selected velocity for moving the weight upward. Also included is a brake applying a negative braking power with a unidirectional braking force opposing the exercise force. The braking power has a braking velocity for permitting downward movement of the weight. A brake controller controls the application of the brake to maintain the braking velocity at a selected constant velocity for at least a selected portion of the user's exercise time. A differential member is coupled to the weight and receives the input power and the braking power. The differential member determines a differential between the user-selected velocity and the selected constant braking velocity, and applies the resultant to movement of the weight. If the user-selected velocity is greater than the braking velocity, the weight is lifted, and if the user-selected velocity is less than the selected constant braking velocity, the weight is lowered. If they match, the weight is maintained in a stationary elevated position.
