Description

An auxiliary training device for flipping in the air

technical field

The invention relates to the technical field of sports training equipment, in particular to an auxiliary training device for flipping in the air.

Background technique

In the skill group of difficult beauty events, the competitive focus of many events is on the completion of the athletes' difficult flip movements. Such as: gymnastics, trampoline, diving, freestyle skiing aerial skills and other sports, all measure the level of athletes' sports level and sports performance by the difficulty and quality of completing flip movements. Mastering high-difficulty flip movements is the main content of the training of athletes in most sports in difficult and difficult sports. How to improve the efficiency and quality of flip movements for athletes in difficult and beautiful sports is a difficult problem for relevant workers.

We know that the mastery of athletes' difficult flip movement skills is based on the formation of a solid movement neural connection through a large number of movement experiences. In training practice, because the athletes have not yet fully experienced the newly learned flip movements with certain difficulty, they usually need to use auxiliary means when they experience the movements. Such as: gymnastics, trampoline, diving and other events often use sea surface pits, protective belts, and trampoline to assist athletes to experience movements; freestyle skiing aerial skills mainly use trampoline or use pools to assist athletes to experience movements.

Undoubtedly, the use of sea surface pits, protective belts, spring nets and pools are all effective auxiliary means to help athletes experience flipping movements and establish and consolidate the neural connection of movements. However, these methods only focus on the establishment and consolidation of flipping movements. As far as neural connection training is concerned, they all have the common deficiency of low efficiency. The specific performance is: every time an athlete practices an action, he needs to consume a certain amount of physical energy to create the space-time flip condition, and then carry out the training to establish and consolidate the neural connection of the flip action under the created space-time condition. Creating the condition of flipping time and space not only consumes the athlete's physical energy, but also consumes the effective time for the athlete to train the aerial flip action, which obviously damages the training effect of the athlete's specific content, and also reduces the training efficiency of the athlete's specific content.

Features of existing training facilities:

Use the sponge pit for training: Athletes stand in a certain space between the high place and the sponge pit, and use this space to perform flipping exercises; athletes complete the take-off action on the edge of the sponge pit, create certain space-time conditions, and perform aerial training under the created space-time conditions. Flip exercise. The sponge pit acts as a buffer to prevent injury.

Use the pulley protective belt for training: the pulley protective belt facility is placed above the equipment, and the athlete actively disengages from the equipment to form a parabolic space-time condition and perform flipping exercises. The pulley protective belt acts as a buffer to prevent injury.

Use the trampoline for training: Athletes use the trampoline to bounce to a certain height to obtain the space-time conditions, and perform aerial flipping exercises under the obtained space-time conditions. The elastic net plays a role in helping to create space-time conditions and cushioning to prevent injuries.

Combining the trampoline with the sponge pit for training: the trampoline is placed on the edge of the sponge pit, and the athletes take off from the trampoline to form a parabolic space-time condition in the direction of the sponge pit, and perform aerial flipping exercises under the formed space-time conditions. The bullet net plays the role of helping to create space-time conditions, and the sponge pit plays the role of cushioning and preventing injuries.

Combination of trampolines and pulley protective belts for training: a pulley protective belt facility is placed above the trammel nets, and athletes use the trampolines to take off to create space-time conditions and perform aerial flip exercises. The elastic net plays the role of helping to create space-time conditions, and the pulley protection belt plays the role of buffering and preventing injuries.

Problems with existing training facilities:

The common advantage of the existing auxiliary training facilities and methods for flipping in the air is that it solves the safety problem of flipping training for athletes under certain time and space conditions. These facilities, such as bullet nets, did not play a substantial role in promoting. This is also the lack of function of these training aids for athletes to specifically establish and consolidate the movement technique training of aerial flip movements.
