Exercise system for shifting an optimum length of peak muscle tension

摘要

The present disclosure relates generally to exercise equipment for enabling a user to vary the effective muscle tension during the course of the performance of an exercise and, more particularly, to an exercise system for shifting an optimum length of peak muscle tension. In some embodiments, the system is an apparatus which comprises a force-generating element, e.g. a fluid cylinder, a user-input element which a user forcibly moves during the course of performance of an exercise, and also a coupling means, which is preferably a cable-pulley system, which transfers forces between the force-generating element and the user-input element. Finally, the apparatus comprises a control unit which controls and varies the level of force generated by the force-generating element during the course of performance of the exercise. The apparatus effectively varies the effective muscle tension through the generation of forces.

主权项

1. An exercise system comprising:
a pneumatic cylinder having a piston movably disposed therein and a port; one or more coupling elements having a portion that is coupled to the piston; one or more user-input elements that are coupled to a portion of the one or more coupling elements; one or more valves configured control air pressure delivered to the port; and one or more electronic control units that are configured to perform operations including at least:
provide an initial pressure level corresponding to one or more levels of displacement resistance of the one or more user-input elements; andadjust pressure away from the initial pressure level in successive increments over a course of an exercise to gradually change the one or more levels of displacement resistance of the one or more user-input elements in response to each instance where one or more repetitions cannot be performed within a specified time.
