ABSTRACT:
Exercise equipment having a reciprocating extendible and retractible tension transmitting device is equipped with a control which restricts the extension to a constant velocity and impose a compulsory constant velocity retraction. The control may be hydraulic or electrical and may be a linear actuator. Transducers, and/or a load cell connected to the apparatus produce signals representing the performance of the user. These signals are processed by a control computer which produces control signals. The computer may also produce signals representing the user's previous performance for display and storage. The display may be an audiovisual display presenting animated graphics representing the user's present exercise performance as compared with the user's previous performance. The display also provides incentive, reinforcement, and motivation based upon the utilization of the comparative performance data. A sound generation system generates encouraging spoken remarks and provides background music.
