Patent ID: 8641581

Claim:
A stationary ergometric exercise apparatus with a hand- or foot-operated drive with two alternately-operable drive elements wherein the drive is joined to a flywheel by means of a gear mechanism; and the apparatus includes a measuring unit for measuring at least one of a drive force applied via the drive and a torque related to the drive force, and a measuring device for measuring an angular position of the drive, wherein the apparatus includes a wheel joined to the drive so as to be synchronous in motion with the drive and the measuring device includes a pair of sensor devices arranged in positions relative to the wheel whereby a signal is generated when the wheel is located at each of two specific angular positions, the positions being located 180° apart and corresponding to positions in motion of a load alternation between the alternately-operable drive elements, and further characterized by an evaluation device configured to receive signals from the measuring unit concerning the drive force applied and/or torque related to it, and to calculate and continuously output temporal progress of the drive force and/or related torque, as well as variables derivable from the drive force, on the basis of the signals delivered by the measuring unit, and wherein the evaluation device is configured to receive signals from the measuring device identifying times of load alternation between the alternately operable drive elements, and use the times of load alternation identified by the measuring device to apportion the variables calculated on the basis of the signals delivered by the measuring unit alternately to a right or left limb of a person in training.
