TRANSLATORY MOTION STRENGTH TRAINING SYSTEM AND METHOD

摘要

A strength training apparatus adapted for conducting translatory motion against a counteracting resistance. The apparatus includes strength training devices wherein a carriage and corresponding guide means are provided for translating mass under the effect of gravity along a rectilinear or curvilinear path. Certain embodiments are configured for utilizing a selectable weight stack, loaded free weights or the user's body weight as a primary resistance that is independent of velocity. The apparatus enhances the results of strength training and exercise equipment for providing velocity-dependent resistance in addition to the primary "static" resistance provided by the apparatus by creating a paced resistance in addition to the primary "static" resistance provided by the apparatus at constant velocity. The apparatus includes both selectable velocity-independent resistance provided by a mass coupled to the carriage acting against gravitational forces and velocity-dependent resistance provided by eddy current resistance caused by the interaction of an electrically conductive structure encountering relative motion with a magnetic field. The electrically conductive structure is secured to a frame and magnetic field is provided by one or more permanent magnets secured to the carriage.
