Infrared ray super-equal-length lower fixing turning core strength training and information feedback device

Abstract

The invention relates to a strength training and information feedback device, in particular to an infrared ray super-equal-length lower fixing turning core strength training and information feedback device. The infrared ray super-equal-length lower fixing turning core strength training and information feedback device aims to solve the problems that no turning core stabilization strength training device for achieving super-equal-length contraction of muscles exists currently and information of motion parameters can not be fed back. An arc surface of a balance base and a base are in rotatable connection; a chassis is fixed to the upper end face of the balance base; a pedal and the chassis are connected through a vertically arranged fixing shaft; the upper end of the fixing shaft and the lower end face of the pedal are fixedly connected; the lower end of the fixing shaft and the chassis are fixedly connected; the fixing shaft at the lower end of the pedal is sleeved with a shaft sleeve; a rotatable damper is installed between the fixing shaft and the shaft sleeve; the lower end of a rotary frame and the outer end face of the shaft sleeve are fixedly connected; the upper end of the rotary frame is provided with two rotary handles; the signal output ends of two distance measuring sensors are connected with a first distance signal input end and a second distance signal input end of a control circuit. The infrared ray super-equal-length lower fixing turning core strength training and information feedback device is used for turning strength training.

Description

technical field

[0001] The invention relates to a human body physical strength training and monitoring device, in particular to an infrared ray ultra-isometric fixed-rotation core strength training and information feedback device. Background technique

[0002] The main function of core strength training is to stabilize the athlete's spine and pelvis, maintain correct body posture, stabilize the center of gravity, improve body control and balance, and increase energy output from core muscles to limbs and other muscles during exercise.

[0003] Core strength emphasizes that the force of the movement should rely on the center of the body. The force of the extremities starts from the force of the trunk and waist, which can extend the moment arm, increase the torque, and obtain greater strength. When the athlete is exercising, the waist to the hip The position of the head is the center of the whole body, which acts as a link for the movement of the whole body. The more developed...
