Description
Technical Field
The invention relates to a training instrument, in particular to an active type difficulty-adjustable human body dynamic balance ability training instrument, and belongs to the field of training instruments.
Background
The balance ability refers to the ability of a person to control the gravity center of the body of the person in a certain space range and ensure that the person can keep balance when doing any action. The balance ability is a necessary condition for helping people to finish standing, walking and coordinated actions in daily life, and is an important index of the athletic skills of athletes. Balance ability training is an indispensable part of physical training of professional athletes such as gymnastics, taekwondo, skis, and the like.
The human body balance can be divided into static balance and dynamic balance. Static balance is the ability of a person or part of a person to remain in a stable state when in a particular position, such as sitting or standing. Dynamic balance is the ability of the human body to automatically adjust and maintain posture while moving or being subjected to external forces. Most sports require that the athlete continuously make posture conversion during the game and keep the body balance when being disturbed by external force, so that the dynamic balance ability of the athlete is very important.
To improve the dynamic balance ability of athletes, unbalanced conditions need to be created during training. The dynamic balance ability training apparatus can be divided into active type and passive type. The passive type refers to a state that an electric motor, hydraulic pressure or pneumatic pressure drive is used to cause sudden external force interference, so as to make unbalance, and the device is generally complex in structure, expensive, heavy and not suitable for large-scale popularization, such as patents CN 110170153a (2019.08.27) and CN 103584869B (2015.02.25). Active means that the device does not adopt any power source, and completely depends on the gravity of the athlete to make an unbalanced state, such as a balance beam, a balance plate and a wave speed ball, and the device is generally simple in structure, low in price and portable.
At present, most active dynamic balance ability training apparatuses have a disadvantage that the training difficulty cannot be adjusted, such as the patents CN 109700468A (2019.05.03) and CN 103638642B (2015.10.28), so that the athletes cannot select the corresponding training difficulty according to their own level to gradually improve their own dynamic balance ability. In view of this, we propose an active dynamic balance ability training apparatus that can precisely adjust the training difficulty.
