Abstract

A physical exercise device providing a stepper like motion for a user may include a pair of foot pedals and a pair of arms for engagement by the user while seated on the seat of the physical exercise device. The pair of foot pedals and the pair of arms may be connected to a drive train which provides contralateral motion between the pair of arms and the pair of foot pedals. A pedal and arm lock mechanism may also be provided which prevents the pedals and arms to be moved in a lock state, while allowing movement of the pedals and the arms when in the unlock state. The physical exercise device may also include computational and data acquisition units for receiving a position signal and pedal force signals and recording the signals.

Claims43

Dependent claims

A physical exercise device providing a stepper like motion for a user comprising:

a pair of foot pedals provided for engagement by the user while seated on a seat,
a drive train providing cyclical counter motion between the foot pedals,
a drive train lock mechanism enabling the pedals to be locked in a locked state at a desired position along their range of motion, and enabling the pedals to be moved in an unlocked state,
a position sensor for providing position signals of the pedals, wherein the pedals move over a range of motion,
pedal force plates for measuring forces exerted by the user on each of the pedals and providing pedal force signals,
a computational and data acquisition unit for receiving the position signal and the pedal force signals and recording the pedal force signals over the position of the drive train and enabling computation of performance of the user in dynamic activity with the drive train lock mechanism in the unlocked state, and enabling computation of performance of the user in static activity with the drive train lock mechanism in the locked state, and
a user interface system incorporating a user interface screen enabling the user to receive information regarding the dynamic and the static activity.
