Description

A kind of dynamic balance ability training equipment with adjustable difficulty

technical field

The invention relates to a training apparatus, in particular to an active human body dynamic balance ability training apparatus with adjustable difficulty, which belongs to the field of training apparatuses.

Background technique

Balance ability refers to the ability of a person to control his body's center of gravity within a certain space to ensure that he can maintain balance when doing any action. Balance ability is a necessary condition to help people complete standing, walking and coordinated movements in daily life, and it is also an important indicator of athlete's motor skills. Balance ability training is an indispensable part of the physical training of professional athletes such as gymnastics, taekwondo, skiing and other athletes.

Human body balance can be divided into static balance and dynamic balance. Static balance is the ability of the human body or a part of the human body to maintain a stable state in a certain posture, such as sitting or standing. Dynamic balance refers to the ability of the human body to automatically adjust and maintain its posture when it is in motion or subjected to external forces. Most sports require athletes to constantly change their posture during competition and maintain their balance when they are disturbed by external forces, so the dynamic balance ability of athletes is very important.

In order to improve the dynamic balance ability of athletes, it is necessary to create an imbalanced state in training. Dynamic balance ability training equipment can be divided into active and passive. The so-called passive type refers to the use of electric motor, hydraulic or pneumatic drive, and the use of sudden external force interference to create an unbalanced state. This kind of equipment is generally complex in structure, expensive, cumbersome, and not suitable for large-scale promotion. CN 110170153A (2019.08.27), CN 103584869B (2015.02.25). Active means that it does not use any form of power source, and completely relies on the athlete's own gravity to create an unbalanced state, such as balance beams, balance boards, and wave speed balls. This kind of equipment is generally simple in structure, cheap and portable.

At present, a major disadvantage of most active dynamic balance ability training equipment is that the training difficulty cannot be adjusted, such as patents CN 109700468A (2019.05.03), CN 103638642B (2015.10.28), so that athletes cannot choose the corresponding training according to their own level. Difficulty training to gradually improve your dynamic balance. In view of this, we propose an active dynamic balance ability training device that can precisely adjust the training difficulty.
