How to avoid injury to the joints in physical education?

Amazing constructions are our joints. Their nature was designed to allow the bones to move. Without them, our arms, legs, neck, and body would not bend at all. However, movement in the joint can occur only in certain directions. For example, the joints on the phalanx of the fingers allow only to bend and unbend them, and the brush in the wrist band can also turn. Thus, some joints have only one-way movements, and others - multidirectional movements.


And what happens if the joint has to perform movement in a plane for which it is not adapted? For example, the knee joint allows the leg to only bend and bend, but we also want to turn it a bit? In a person who has an active lifestyle, the muscles and ligaments surrounding the joint are at the bottom. They are strong, elastic, well supplied with blood - and in emergency situations will work like armor, protecting the joint from the wrong movement.

If a person with sports on you, then his muscles and ligaments are partially atrophied. Too there is excess weight. This is an additional serious load, and if the muscles with it are not controlled, the excess pressure is transferred to the bones. So it turns out: joints and so move to the limit of their capabilities, and then there is an unsuccessful turn ... And the joint is injured.

The shoulder joint has the shape of a ball, which allows you to perform movements within 360 degrees.


Shoulder

The most atypical articulation for the body. In the remaining joints, the bones rest against the cartilaginous tissue. But there is nothing to rest on the bones of the shoulder joint: the next bone is the clavicle, but it is located not above, but on the side. So it turns out that the shoulder from above is limited only by the muscles of the ligament. If they are weak, the joint can easily be injured.

Elbow

The elbow joint is more protected than the humerus, but it is surrounded by relatively long and thin ligaments.

What is dangerous?

Knee

The knee joint is one of the most vulnerable places for slimming, running and cycling. He has the biggest load - the weight of the whole body. The main supplier of nutrients, as well as the protector of the knee joint, is the quadriceps femoris muscle, one of the most powerful muscles of the body, located on the front surface of the thigh. Ladies do not like to train her, believing that pumped up the legs are not feminine. Meanwhile, the glamorous "sophistication" of this muscle becomes the cause of problems with the knees in adulthood.

Hip Joint

The design of the joint is quite complex, so it can perform many different movements. He is traumatized more often by the fall of the Judar. Negative on the joint affects and excess weight: it increases the risk of developing coxarthrosis by 5-10%.

What is dangerous?

Back

The spine is the largest and most complex joint of the body, consisting of many small joints. From injuries and unsuccessful movements, he protects the crooks, but supports his muscles and ligaments, which are strengthened in the first place by walking. The deep muscles surrounding the spine must keep it vertically, not allowing the person to bend, to fall forward or backward under the influence of gravity. Therefore, the best training here is a static retention of the body in a vertical position.
