发明名称 EXERCISE APPARATUS
摘要 An exercise apparatus equipped with an electrically controlled brake (24) may be used for providing resistance force to movement of a holder bar (18) by a user. A rotational transducer (28) is provided to control the brake (24) so that the magnitude of resistance force is varied with movements made by the user. A direction sensing and control circuit is provided to vary the amount of resistance force according to the direction of movement by the user.
