Causes of knee joint injury:
1. The action is not standard.
In our daily training and sports, many people do this action after watching it once, but they don't carefully observe and study how to do it, just imitate the external form. In the basketball game, every excellent dribbler will have a lot of scoring space, such as an emergency stop and a big change of direction.
I believe many friends like the jump shot of basketball players in the game, and then we imitate this action in daily basketball, but I don't know how many times they correct their technical moves behind their backs and train their knees to resist torsion and training. If you just imitate blindly, you will only hurt yourself.
Step 2 be sedentary
For those of us who sit for a long time and exercise less, the synovial fluid secretion of the knee joint will be less. When the knee joint is not nourished by synovial fluid, the friction between bones will increase and the joint activity will be limited. Therefore, when the knee joint moves, the wear will become more and more serious, which will greatly increase the possibility of knee joint injury. Nowadays, among our young people, there are more and more knee joint problems caused by sedentary.
3. Too much training
This reason is more common among athletes, because we ordinary people basically have little training and seldom train too much. Too much training will exceed the endurance of the knee and lead to injury. For example, in running training, the knee joint is used in a large amount, and repeated rubbing, bending and stretching for a long time can easily cause surface wear and ligament damage of the knee joint.
4. Overweight
The last reason is that long-term overweight will cause extra damage to the knee joint, so it is suggested that overweight people should exercise slowly first and then do high-intensity exercise after losing weight.
