Description

Dance shank ligament trainer

Technical Field

The utility model relates to a ligament training technical field, concretely relates to dance shank ligament trainer.

Background

The ligament is actually a form of warming up, and the tendon is stretched before strenuous activity, so as to prevent the ligament from being unable to bear, injured or broken and pulled due to sudden acceleration. The bearing capacity of the body bending degree and the extending capacity of each limb are improved by pulling the ligament. People of different ages need to consider their age when pulling the ligament. Basically, the ligaments of a person differ before and after the age of 14 to 17. After 16 years of age, the bone develops a basic set, and therefore the ligaments are set. Therefore, younger people recommend that they use the tremor method. In the stretching position, the ligament is pulled to be at the limit by the tremolo motion. The effect of this pulling is significant. However, for persons with relatively mature bones. This method only allows for short-term ligament stretching. But also dangerous and vulnerable. Therefore, for those over 16 years of age, hydrostatic pressure is recommended. The patient is kept in a limit posture for 30 seconds, and then is rested for a few seconds, and then the posture is kept. It is generally recommended that the ultimate posture of stretching does not exceed 30 seconds. Otherwise muscle injuries in the opposite direction may result. This method of hydrostatic pressure will maintain a stable fixation of the ligament for a relatively long period of time.

General dance rooms will all be equipped with the trainer that is used for stretching the ligament, and the student needs a leg to land on the ground, and a leg is fixed on the trainer, but if the student that just begins to study dance practises, because the ligament has not yet pulled open completely, needs the trainer that highly is lower, but along with the going on of practising, the student needs higher trainer to be changed, and it is not only troublesome to change the training and change the device, has still caused the wasting of resources. Furthermore, the new-born training devices without guards may fall down due to unstable standing on one leg, so the conventional training devices have a certain risk.
