First, ball games, physical imbalance.

Badminton, volleyball, basketball, football, etc. When scoring, pitching and catching the ball, the body is in a state of weightlessness, or it is completed at the moment of turning around. This puts a lot of pressure on the knee joint, and this pressure is unbalanced. Knees often encounter this kind of uneven pressure, and injuries are inevitable. 1. Basketball defense, attack, stop jump shot, cut-in defense, rebound or dunk to the ground, foot contact with the ground, etc. It's really common in sports. Whether it is sudden take-off or landing, it is often accompanied by the rotation of the body, which is easy to cause meniscus injury.

2. Football is running at high speed. Because football is a sport that requires feet, the damage to the meniscus will be higher. Whether it is forward, defense or even turning around, eversion or eversion can occur. When we land, because the center of gravity is unstable, it often leads to the gathering place of knee joint flashing left and right.

3. Football is also a competitive sport, which will also have a certain impact on the meniscus. There are sprinters, because a lot of strength will break out in a short time and will be concentrated, so sprinting is also very easy to damage the meniscus.

Second, mountain climbing, excessive stair project.

Everyone thinks that climbing a mountain and going up the steps is a heavy load on the knees. Because the center of gravity of the human body is not between the legs and does not move on a plane. Push the front leg muscles to move the center of gravity up. Moreover, continuous climbing will cause excessive fatigue of leg muscles, thus reducing the protective ability of muscles to joints and joints, and injuries are inevitable.

Third, there are too many casing projects.

Too many squats in the gym! Whether you lose weight or gain muscle, you can't do without squat, and most of them are weight-bearing squats. The pressure on the knee joint can be imagined. Therefore, different physical abilities should have different training plans. The number, group number and weight of squatting legs vary from person to person. Overtraining or imitating others rashly all lay a hidden danger for knee joint injury. For example, weightlifters should be explosive in an instant, especially pay attention to the shift of center of gravity. If it is unstable, it is easy to cause damage to the meniscus. Weightlifting, for example, often leads to the knee joint flashing left and right, buckling and turning, and the sudden increase of strength often brings a great burden to the knees.

The above is what I know will cause meniscus injury!
