Maximum muscle strengthening resistance device

Abstract

A maximum muscle strengthening resistance device provides a way of exercise that allows the exercising person to exert his / her full power throughout the whole time of exercise. When a volume of fluid is forced to pass through a small opening, it produces a resisting force. This invention uses this resistive force produced by the oil flow along with the mechanical force generated by a power unit such as a hydraulic pump or an electric power motor for the resisting force during the strengthening exercises. Most of the muscle strengthening exercise is consisted of consecutive concentric-eccentric exercise cycles. By using this invention, during the concentric exercise cycle the exercising person actively exert his / her full power to move the exercising handle toward the concentric direction against above mentioned resistive force of oil flow. During the eccentric exercise the power unit moves the exercising handle toward the eccentric direction and the exercising person attempts to stop the movement by exerting his / her full power. The amount of the force exerted by the exercising person during the concentric-eccentric cycle is displayed on the monitor screen for monitoring.

Description

PRIOR APPLICATION[0001]This application emanates from a prior Provisional Patent Application No. 60 / 684383 filed May 25, 2005.FIELD OF THE INVENTION[0002]This invention relates to the field of muscle strengthening exercise device. In particular, this invention involves a device that enables a person to exert his / her full power throughout the full range of motion during the whole time of exercise when the person exercises using this device.BACKGROUND OF THE INVENTION[0003]Until now most common muscle strengthening exercises have been performed by weight lifting that equal amount of weight is applied throughout the whole range of motion no matter how much the muscle is tired out. Therefore, initially the person performing the weight training lifts weight easily that there is not much exercise effect, and later as his / her muscle is getting tired the exercise gives strengthening effect to the muscle. However, very soon the person is getting more tired, and he / she is no more able to lift...

AI Technical Summary

Benefits of technology

[0012]As described above, this invention allows the exercising person exert his maximum power in both concentric exercise and eccentric exercise procedure. An oil pressure sensor is installed in the resistance cylinder set and shows the pressure inside of the resistance cylinder through the connected monitor screen that allows the exercising person monitors how much power he is exerting during the exercises. By changing the size of resistance control opening with automatic valve in the concentric exercise and by changing the speed of the said hydraulic pump or electric power motor in the eccentric exercise, the person can exercise in various speeds while he is still using his full power.

Problems solved by technology

However, very soon the person is getting more tired, and he / she is no more able to lift the weight and have to stop.

If someone wants to increase speed, they need use lighter weight and work fast, but as the weight is light, it is not effective to strengthen the muscle, and need to make more repeat until the muscle is tired up, and at that point he / she is no more be able to exercise fast enough to get the speed.

Isotonic exercise is most common weight training that uses same amount of weight throughout the full range of motion but that can not give 100% muscle power exertion until the muscle is tired up and cannot lift the weight anymore.

Isometric exercise gives 100% force exertion but it cannot give range of motion exercise.
