Description

Technical Field

[0001] The invention relates to the technical field of high jump auxiliary equipment, in particular to an auxiliary equipment used for high jump training. Background Art

[0002] High jump is one of the field events in track and field sports. It is a sport in which the human body jumps over high obstacles through a series of actions including running-up, taking off, flying, and landing. The score is calculated by jumping over the upper edge of the bar. The back jump is the most superior way to jump over the bar because the center of gravity of the body is closer to the bar, or even lower than the height of the bar. It can make full use of the flying height and is widely used in competitions. Since the waist and legs are used to generate force during the jumping process, athletes need to train their legs and waist to increase their jumping ability and protect their waist.

[0003] In the prior art, for example, the Chinese patent number CN108261715B, "High Jump Training Equipment for Sports Training", includes a rubber plastic plate, a movable through hole and a positioning bolt; a rubber plastic plate is laid on the bottom surface of the front end of the cushion box body; two vertically upward high jump frames are fixed at the front ends of the side walls of both ends of the cushion box body. The arrangement of the electroluminescent color-changing material plate and the pressure sensor of the present invention is achieved by laying an L-shaped runway paved with a plurality of pressure sensors on both sides of the left and right ends of the bottom of the rubber plastic plate.

[0004] In the prior art, when high jumping, the waist and legs need to be used to generate force so that the athlete can jump higher, so the athlete's waist and legs need to be trained. Although the above patent can train the athlete's legs, it cannot stretch the athlete's legs after training the athlete, which will affect the athlete's leg ligaments. Moreover, when the athlete trains the waist, he cannot directly train his own waist, which reduces the force point of the waist and causes the flexibility and agility of the waist to decrease. Therefore, an auxiliary device for high jump training is proposed. Summary of the invention
