Description
Technical Field
The invention relates to the field of exercise balance training, in particular to a feedback type balance training device.
Background
With the development of sports technology, the existing physical training classification is increasingly fine, and the basic skills of sports are divided into three categories: motor skills, balance skills, and composite skills. Motor skills refer to a person's ability to move from place to place, including walking, jogging, sprinting, swimming, and the like. Comprehensive skills refer to controlling the body through comprehensive movements of hands and feet, including throwing, hitting and the like. Balancing skills refer to the ability to achieve physical stability with minimal support in all of the above motions. In the process of movement, the balance ability is the basis of movement and the most important factor in the movement, and the movement safety is also determined to a great extent.
Since the ability to balance energy is a guarantee and a prerequisite for completing various actions, it is one of the indispensable training points for athletes of various projects to improve the balance ability in the sport.
Based on the standing movement characteristics of human beings, the balance ability of the lower limbs is generally the core and key point of balance training in balance training. In the daily strength training for strengthening the core muscle group and various aerobic training, if the balance ability of the lower limbs, particularly the ankle joints, cannot keep up, the exercise is easily twisted to a great extent while other training is hindered and influenced. This is mainly because the lower limbs are required to keep the balance and stability of the joints during exercise due to the large torsion, change, and sway of the body posture and the high-strength weight training, and if the muscles of the joints are insufficient to maintain the control force on the joints, the joints are unbalanced, resulting in sprains of the knees and ankles. Severe cases cause habitual dislocation, which leads to more severe exercise impairment. Therefore, the existing balance training is generally based on ankle joint for stable training, further enhances the training of lower limb strength (mainly comprising calf muscle group), and finally enters core stable and functional stable training. In summary, stable balance training of ankle and lower limbs is the basis and precondition of balance training. In the training, various practices show that simple auxiliary instruments such as a wave velocity ball and a balance board can be used only according to the feeling trial, the training precision cannot be controlled, data and indexes cannot be matched, and the requirements of professional training cannot be met. Meanwhile, the training device is very unsafe, and sprain usually occurs in training. Meanwhile, some large-scale balance training devices are common in balance training, and the training condition is determined through video and electronic feedback. However, such large equipment has problems in use including: 1) the equipment is huge, the structure is complex, the cost is high, the purchase price is high, the equipment is difficult to move when needing to be placed in a large space, and the equipment can only be used at fixed points. 2) Generally, analog feedback is performed through electronic means such as voltage induction, which is not intuitive, and difficulty and strength are fixedly set, so that the trainer who is difficult to adapt to different physical conditions can not make targeted adjustment. Therefore, the prior art lacks a balance training device which has strong universality, intuitive, safe and convenient operation and lower cost.
