Triple jump posture correction and training device

Abstract

Disclosed is a triple jump posture correcting and training device. The device comprises a hopping section, a leaping section, a jumping section and a landing section which are arranged in sequence from front to back, the device is characterized in that the hopping section and the leaping section are located on one inclined plane, the height of the inclined plane is increased gradually from front to back, the jumping section comprises a first connecting part, a second connecting part and a middle elastic part, and the two sides of an elastic plate and a substrate are separately provided with a set of fixed mechanism; an air bag is connected with an air supply system to supply air for an air spring. The second connecting part is located at the back end of the substrate and is connected with the landing section in a plugged mode through a plugging structure, the landing section comprises a ground groove, the air bag, ground mats and a smoothing mechanism, wherein the air bag is filled in the ground groove, the ground mats are located at the upper portion of the air bag, and are placed in an overlaid mode, the upper surface of each ground mat is long flannelette fabric, and the long flannelette is red and blue after combed in the forward direction and in the reverse direction. According to the triple jump posture correcting and training device, in the process of take-off, the spring and the air spring are used for assistance, the physical power consumption can be reduced, the training times are increased, and the optimal training effect is achieved.

Description

technical field [0001] The invention relates to a training apparatus for triple jump. Background technique [0002] Triple jump is a sport in which three consecutive jumps are performed along a straight line after the run-up. It is a sports event composed of three consecutive movements of hop, step jump and jump. It is also a kind of event in the school spring sports meeting. Engaged in triple jump practice, there is currently no special equipment. [0003] The triple jump is now performed using sand traps on the playground. Because this sport puts a heavy burden on the lower limbs, the requirements for physical fitness are higher than other sports. It requires athletes to have fast approach speed, good jumping ability, and strong leg strength, so physical strength should be improved during training. Consumption is larger. Middle school students, as non-professional sports personnel, have relatively rapid physical exertion during training. [0004] The correct posture of...

Engaged in the practice of triple jump, currently there is no special equipment

No special research and equipment

[0005] At the same time, among the existing school resources, there are few bunkers. A stadium is usually equipped with 1 to 3 bunkers, which is difficult to meet the needs of students' daily training.
