Isokinetic strength training power device and isokinetic motion implementation method

Abstract

The invention discloses an isokinetic strength training power device and an isokinetic motion implementation method, and relates to the field of isokinetic motion. The device comprises a resistance source module, a signal acquisition module and a control module, wherein the resistance source module is used for generating resistance, the control module is used for adjusting the resistance by controlling a valve component in a resistance source, and the signal acquisition module is used for acquiring a force signal and a displacement signal for processing. Through a relation model among speed, force and pulse valve switching frequency, force data and motion speed data are detected to quickly find equivalent resistance generated by adjusting oil flow resistance through a PWM control pulse valve corresponding to the data, and isokinetic motion is achieved. The cost of constant-speed movement is reduced, popularization is easy, the pulse valve is adopted for controlling the oil speed, F-PWM relation curve graphs at different speeds V are obtained through tension testing and data regression fitting, the PWM duty ratio output by a single-chip microcomputer is rapidly obtained and calculated based on the F-PWM relation curve graphs, isokinetic motion is achieved, the response speed is high, and control is accurate.

Description

technical field [0001] The invention relates to the field of isokinetic exercise, in particular to a power device for isokinetic strength training and a method for realizing isokinetic exercise. Background technique [0002] Isokinetic exercise is the contraction training of muscles under constant velocity conditions. This kind of muscle contraction can exert the maximum muscle strength training regardless of the joint angle. The isokinetic muscle strength training equipment can provide compliance resistance in the full range of joint movement, and A pair of antagonistic muscle groups can be trained at the same time, effectively avoiding the imbalance of muscle function recovery. Due to the inconvenient speed in isokinetic exercise, the resistance can be adjusted, and the compliance resistance generated with the strength of muscle contraction can make the muscles in the full range of motion of the joints. Therefore, it can more effectively exercise muscle strength, endurance...
