Active/passive exercise apparatus

Abstract

In the subject apparatus, the user lies back down on a platform which is roller mounted on parallel tracks and movable from end to end of the tracks. The platform is biased toward a position essentially midway between the ends by primary and secondary energy storage and release apparatuses. The secondary apparatus is engaged by the platform after it has moved partway toward one end or the other. Both apparatuses are adjustable in terms of spring rates and storage capacities. The engagement points of the platform with the secondary apparatus are adjustable. Hand grips are attached to the track assembly by cables and are used by the user for setting the platform into oscillating motion on the track. A footrest is also attached to the track assembly so that the user can set the platform into motion by applying foot pressure with either or both feet in combination, if desired, with force exerted by either or both hands. The acceleration forces achievable are in excess of the force of gravity and the platform is equipped with supports and stops for stabilizing the position of the user on the platform. The exercise provides cardiovascular stimulation, passive exercise of all components of the body and the active exercise of setting the platform in motion and maintaining the motion.
