SYSTEM FOR MUSCLE DEVELOPMENT BASED ON ECCENTRIC, CONCENTRIC AND ISOMERIC CONTRACTIONS OF AGONISTIC AND ANTAGONISTIC MUSCLES, REACTIVE TO THE DIRECTION OF THE FORCE

摘要

The invention relates to a motor-driven device for concentric, isometric and eccentric muscle development, the triggering direction of which is reactive to the direction of the force of the user. The invention specifically relates to a motor-driven device with two operating directions, which reacts to the force of a user in order to counteract with an adjustable muscle-development load in a reversible movement. It consists of: a reversible motor-driven support which moves a mobile support (2)(30)(51) on which a part of the body is supported, and provides a muscle-development load; and a stationary support (3)(33)(52) on which another part of the body is supported so as to counteract the motor-driven force of the mobile support (2)(30)(51). A system (6)(39)(58) for detecting the direction of the force of the user allows the control of the mechanism such that it can be motor-driven in the reverse direction, or stopped if the force of the user becomes insufficient. The device according to the invention particularly targets muscle development based on isometric, concentric and eccentric contractions, that can be adapted to all sports activities. The device according to the invention can take the form of structures allowing vertical, horizontal or rotary types of force, or a combination of said types.
