Training apparatus
InactiveUS20060234832A1Lessen the training loadKeep motivatedClubsDumb-bellsPhysical exerciseEngineering
A training apparatus is disclosed which allows a trainee to attain a sense of accomplishment by continuing an exercise until a target is reached, without undue strain. A torque motor applies a load to a handle bar, which is driven by the exercise of a trainee. If the movement of the trainee who moves the handle bar is about to stop, then the load is gradually reduced. If the handle bar once again begins to move due to a load reduction, then it is inferred that the trainee has resumed the exercise, and the load at that time is maintained until, for example, the direction of motion of the handle bar changes. By gradually reducing the load at the fatigue limit of the trainee, it is possible to promote the resumption and the continuance of the exercise.
