A kind of reaction type balance training
Technical field
The present invention relates to moving equilibriums to train field, specifically a kind of reaction type balance training.
Background technology
With the development of sports technology, existing physical training classification is more and more thinner, and the foundational skills of sport are divided into three greatly
Class:Motor skill, balance technical ability and integrating skills.Motor skill refers to the ability of people from one place to another,
It contains away, jogs, sprints, swims.Integrating skills refers to controlling body by the comprehensive movement of trick, including throw
It throws, strike.Balance technical ability refers in above-mentioned all movements using minimum support to reach the ability of body steadiness.
In motion process, balanced capacity is both the basis of movement, and factor mostly important in movement, while also largely
Determine sports safety.
Since flat energy ability is guarantee and the premise of completion various actions, therefore for the sportsman of each project, carry
Balanced capacity in height movement is one of indispensable training emphasis.
Standing movement characteristic based on the mankind, in balance training, the balanced capacity of lower limb is usually the core of balance training
The heart and emphasis.In the strength building of daily reinforcement core muscle group, and every aerobic training, if lower limb, especially ankle closes
The balanced capacity of section is not caught up with, and is not only hindered and is influenced the progress of other training, also largely easily cause sprain for exercise.
This is primarily due to during exercise, and significantly torsion, variation, shaking and the weight training of high intensity of body gesture need
Lower limb aprowl keep the balance and stabilization of joint, once the muscle of joint is not enough to keep the control force to joint,
Joint part will be made unbalance, cause the strain of knee, ankle-joint.Severe patient causes habitually to dislocate, and causes more serious
Locomotor damage.Therefore existing balance training, stablize training typically based on ankle-joint, and then reinforce to lower limbs strength
Training (based on Calf muscle group), finally enter core stable and the functional training stablized.It is to sum up known, ankle-joint and under
Limb stable equilibrium training is basis and the premise of balance training.In this training, by items practice have shown that, using simple
Auxiliary instrument, such as velocity of wave ball, balance plate etc., on the one hand, can only perceptually sound out use, be unable to control trained essence
Degree, unlikely has data and index to match, cannot meet the requirement of professional training.Also very dangerous simultaneously, it is commonly in
There is a situation where sprain in training.Meanwhile also some common large-scale balance training equipment in balance training, pass through video, electricity
Son feeds back to determine trained situation.However this large scale equipment in use with the problem of include:1) equipment is huge, structure
It is complicated, cost is higher, causes to purchase expensive, while needing larger space to place, be also difficult to move, can only pinpoint makes
With.2) analog feedback generally is carried out by electronicallies such as voltage induceds, not intuitively, and difficulty, intensity are fixed setting, difficult
Trainer to adapt to different strength situations, which makes, targetedly to be adjusted.Therefore the prior art is still scarce a kind of versatile, operation is straight
It sees, safely, conveniently and lower-cost balance training.
