technical field

The present invention relates to sports training equipment. It also relates to a balance training device.

Background technique

With the development of sports technology, the classification of existing physical training is becoming more and more detailed. The basic skills of sports are divided into three categories: sports skills, balance skills and comprehensive skills. Motor skills refer to a person's ability to get from one place to another and include walking, jogging and sprinting, as well as swimming. Balance skills refer to the ability to use the smallest support to achieve body stability during sports. Balance is the most important factor in sports and the basic skill of many sports. Synthetic skills are where the trainer controls the body through comprehensive movements of the hands and feet, including throwing and hitting.

Balance ability is the guarantee to complete the action. Balance ability can be divided into static balance ability and dynamic balance ability. Static balance ability refers to the ability to maintain balance in a static state, such as the balance state when standing on one foot. Dynamic balance refers to the ability to maintain balance and control the body during exercise.

In the current training, not enough attention is paid to balance exercises, and there are not many practice methods. Commonly used equipment includes balance beams, balance boards, and speed balls, etc., which lack quantitative monitoring of balance exercises.
