Multifunctional aerobics physical training teaching device

Abstract

The invention discloses a multifunctional aerobics physical training teaching device. The device comprises a stretching device and a leg pressing device. The inner part of an arch bridge of the stretching device is provided with a plurality of bendable flexible reinforcing steel bars. Radian of the reinforcing steel bar is matched with radian of the arch bridge. The top of the arch bridge is provided with an arc spring. The top of the arc spring is an arc concave surface, and the arc spring is made of a soft material. A bending sensor is arranged in the arc spring. A base is provided with a voice player. Through the device, an athlete can stretch a body through arranging an arch frame, to train body flexibility of a trainer. The arc spring is arranged on the arch frame, and the bending sensor is arranged in the arc spring, so curvature of a waist of the trainer can be detected in real time in back-bending training of the trainer, and the curvature is played through the voice player, and the trainer can conveniently know training posture of the trainer according to the curvature of the waist.

Description

technical field [0001] The invention relates to the technical field of sports equipment, in particular to a multifunctional aerobics body training teaching device. Background technique [0002] Aerobics is a kind of aerobic exercise, which is characterized by a certain period of time and low-level whole-body exercise. It mainly exercises the cardiopulmonary function of the practitioner. It is the basis of aerobic endurance and has high requirements for the athlete's own physical quality. . Body posture plays a pivotal role in aerobics, and is an important aspect that referees consider when assessing the pros and cons of techniques. Athletes generally train in terms of flexibility, leg pressing, and strength. [0003] In terms of flexibility and leg pressing, the existing aerobics body training devices are often performed by a group of trainees according to unified standards. The training equipment is generally bar equipment, and the height adjustment is not accurate enough....

AI Technical Summary

Problems solved by technology

[0003] Existing aerobics body training devices are often performed by a group of students in accordance with a unified standard in terms of flexibility and leg pressing. The training equipment is generally a pole-type equipment, and the height adjustment is not accurate enough. In addition, individual physical conditions are different. According to the same textbook training, it will often cause waist and leg muscle strain, and long-term training will bring great harm to bodybuilding dancers.

[0004] To sum up, the existing aerobics body training devices have low intelligence, which makes the aerobics dancers easily injured, thus reducing the training effect
