Ligament stretching device for aerobics training

Abstract

The invention discloses a ligament stretching device for aerobics training, which comprises a base. A traction seat is arranged at one end of the base, a cushion is arranged at the other end of the body, a sliding groove is reversely formed in the base along the length direction, the traction seat is arranged in the sliding groove in a sliding manner, a traction mechanism used for driving the traction seat to be away from the cushion is arranged between the sliding groove and the traction seat, a grip is arranged on the side wall of the traction seat, positioning frames are arranged on the twosides of the base, a positioning rod is arranged on the positioning frame in the length direction, the positioning rod is arranged on the positioning frame in a rotating mode, a plurality of abuttingidler wheels with gradually-increased diameters are arranged on the positioning rod in a sliding mode, the abutting idler wheels are eccentrically arranged on the positioning rod, a locking piece used for limiting sliding of the abutting idler wheels is arranged on the positioning rod, and a driving piece used for driving the positioning rod to rotate is further arranged on the positioning frame.The device can assist in exercising and stretching of side-by-side stretching and knee bending, and the exercising and stretching effect is improved.

Description

technical field [0001] The invention relates to a physical education teaching appliance, in particular to a ligament stretching device used for aerobics training. Background technique [0002] With the diversification and development of university physical education courses, various sports projects are also carried out on university campuses. Aerobics is a popular item that is loved by the masses and has strong popularity. Group exercises, dance, music, fitness, entertainment In one sport, aerobics absorbs a lot of upper and lower limbs, trunk, head and neck and foot steps in disco dance, jazz dance and break dance. It has higher requirements for lower limb strength and flexibility in school and practice. In the development of aerobics courses, the most important thing is the initial stretching warm-up, which helps to improve the flexibility of the practitioner and at the same time exercises the muscles.

[0002] With the diversification and development of university physical education courses, various sports projects are also carried out on university campuses. Aerobics is a popular item that is loved by the masses and has strong popularity. Group exercises, dance, music, fitness, entertainment In one sport, aerobics absorbs a lot of upper and lower limbs, trunk, head and neck and foot steps in disco dance, jazz dance and break dance. It has higher requirements for lower limb strength and flexibility in school and practice. In the development of aerobics courses, the most important thing is the initial stretching warm-up, which helps to improve the flexibility of the practitioner and at the same time exercises the muscles. The stretching warm-up usually includes strengthening the thigh adductors, popliteal muscles, etc. The exercise of leg muscles such as hamstrings, gluteal muscles, and gastrocnemius muscles, so in the development of aerobics courses, especially the stretching exercise before class is very important. At present, students are usually required to pass parallel foot stretching in pre-class stretching. However, during the stretching process of students, single-person exercises cannot complete the movement requirements well, and cannot stretch well in place. Usually, two-person cooperation is required, but the exercises between students are the same. There are cases of being afraid of pain and putting water on each other, and being perfunctory, which is not conducive to the stretching exercise of muscle groups and is not conducive to the development of follow-up courses
