Abstract

An operating unit (14) is detachably mounted on frame (12) in the form of a chair. The operating unit includes a lever arm assembly (16) mounted on a subframe (18) and rotatable by the leg of the user in opposition to a fluid resistance unit (20). A transducer (24) measures the angular rotation of the lever arm assembly which information is transmitted to an integrated circuit (30) disposed within a portable housing (32) removably mounted on the subframe. The integrated circuit stores the data received from the transducer and calculates various values related to the use of the present invention for presentation on display units (208) and (210). An interface (222) is provided to access the integrated circuit to transmit the stored data to a remotely located data processor (220) and for processing of the data or for long term storage of the data.
