SYSTEM FOR MUSCLE DEVELOPMENT BASED ON ECCENTRIC, CONCENTRIC AND ISOMETRIC 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, with 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

1) A body-building device, reactive to the direction of an effort, enabling eccentric, concentric and isometric muscles contractions of agonists and antagonists muscles. The device is composed of:
A motorized mechanism (5) (34) (53) in two opposite directions of operation which provides for each direction a motorized force with adjustable intensity (8) (9) to a movable support (2) (30) (51) on which a part of the body of the user is supported and exerts an effort, A fixed support (3) (33) (52) allowing the user to take a second support to resist in either direction the motorized strength of the mobile support (2) (30) (51); Characterized in that the acquisition by a detection system (6) (39) (58) of the direction of a minimum effort applied by the user on the supports with a preset intensity (2)(30)(51) and (3)(33)(52), starts a reversible motorized mechanism (5)(34)(53) that transmits its motive force to the mobile support (2)(30)(51) in the opposite direction to the detected direction of the user minimum effort and also causes the inversion of the displacement direction when the user reverses the direction of his minimum effort: there is an instant inversion of the direction of the motorized force that occurs on the mobile support (2) (30) (51) and the resulting displacement of the mobile support (2)(30)(51), which provides during the exercise: When the intensity of the user's effort is lower than the intensity of the power strength: the direction of the mobile support motorized force (2) (30) (51) remains in the opposite direction to the user's effort and the mobile support displacement (2)(30)(51) stays in the opposite direction to the user effort, When the intensity of the user effort is equal to the intensity of the motorized force, the mobile support (2) (30) (51) is stabilized and comes to a standstill while the direction of the motorized force remains in the opposite direction to the user effort, When the intensity of the user effort is greater than the intensity of the power strength: whereas the direction of the motorized force remains in the opposite direction to the user effort, the displacement of the mobile support (2)(30)(51) is reversed and follows the same direction as the user effort, When the intensity of the user effort is lower than the minimum safety effort: the motorized mechanism is shut down (5) (34) (53).
