Why do dancers press their knees?

Dancers have to press their knees because there is a group of ligaments behind the knees that need to be pulled apart when warming up, and also because some people are born with big knees because the ligaments behind the knees haven't been pulled apart, so to press the knees is to make the legs look straighter.

The knee joint is not only a key point in dance training and performance, but also may directly affect the tension and texture of the dance movement (especially the legs of the dance movement), has a very important function in dance training.

The knee joint has a lot of taut movements in dance training, and the muscles of the thigh and calf are more frequent, if you don't master the power of the muscles, it is easy to cause soft tissue injuries or wear and tear of the cartilage in the knee joint.

To pay attention to enhance muscle strength and weaken the impact of the knee joint, once the discomfort, to stop dancing, rest for a period of time. Try to wear knee pads when practicing special moves like chin-ups.

The factors of dancers' locomotor organ injuries are:

1, the actor's poor physical fitness

In carrying out long hours of practicing and rehearsing In the long practice, rehearsal, due to the weak ability of strong muscle contraction, thus exacerbating the repeated friction and pulling of the tendons, easy to cause bursitis, tenosynovitis and joint sprains.

2, the local load is too heavy

Single, sudden training of a movement, beyond the body's ability to bear the relevant organs of motion; excessive squeezing, pulling or twisting, will cause these parts of the local microscopic injuries - strain.

3, poor general health

In the case of illness, injury or long time without practice, into the intense rehearsal or performance, the muscles lack sufficient contraction efficiency, and the related antagonistic muscles can not work in a coordinated manner. The range of motion, flexibility and speed of movement of the joints are also weakened. Injuries of various natures may occur.

4, inadequate preparatory activities

Preparatory activities can make the nervous system in a good state of excitement, dominated by the body's various organs to actively participate in the activities, can increase the temperature of the muscles, to overcome the body's inertia, speed up the blood circulation, which improves the contraction of the muscles, improve the muscle's elasticity, spread and flexibility. Necessary preparatory activities are important measures to prevent various injuries.

5, the whole body fatigue

Excessive fatigue, especially the fatigue of the cerebral cortex, resulting in the actor's muscle strength and coordination decline, the joints become inflexible, the human body can not ensure precise stability.

6, poor training facilities

Insufficient light in the classroom, improper hardness of the floor as well as inappropriate shoes and socks, etc., are prone to localized injuries.
