First, people without knee injuries can train according to their leg conditions, such as squatting, climbing stairs and climbing mountains.
Climbing mountains and stairs can exercise the bearing capacity of joints and increase the muscle strength of legs and legs for healthy people.
Jogging and bouncing, badminton, tennis and other sports all belong to bouncing sports, which can increase the elasticity of knee joint and the toughness of ligament at knee joint.
However, no matter what kind of sports, we must adhere to the principle of moderation. Middle-aged and elderly people have fragile bones and poor lubrication of knee joints, which is not suitable for large-scale exercise. When climbing mountains and stairs, they can keep a slow pace and don't exercise for too long at a time. At the same time, the elderly should try not to bounce their knees. Young people, on the other hand, have strong plasticity and their bodies can develop properly. They can even do some difficult movements that normal people can't do, but they should also pay attention to the safety of their knees.
Second, people with knee injuries can choose a more gentle way to exercise their knees, such as walking and other sports with little knee movement, as well as inactive sports such as sitting and squatting. These sports have little stimulation on the knee joint, which will not make the injury more serious and increase the flexibility of the knee to a certain extent.
When squatting quietly, pay attention to the back of the wall, the calf is vertical to the ground, and adjust the squat range according to your endurance. Take a rest when you are tired, and your back and hips can share the weight of your legs appropriately. Long-term persistence can increase the toughness of the knee.
Therefore, improper leg training will hurt the knee, and the injured knee may also recover from leg training. It is very important to master proper leg training posture and strength. No matter how healthy people practice their legs too much, they will hurt their knees. People who have been injured can also recover their injuries through reasonable leg exercises.
