How to protect the knee joint when playing badminton?

When the striding foot hits the ground, the knee will continue to move forward according to inertia. At this time, the meniscus and anterior cruciate ligament are under great stress. As the knee moves forward, the anterior cruciate ligament will become tighter and tighter, which means that the angle between the calf and thigh is greater than 90 degrees when stepping, which is more conducive to protecting the knee tissue.

Badminton had better choose soft ground, such as plastic or wooden floor. Try not to play badminton on the hard cement floor for a long time, otherwise it will easily cause knee joint injury.

Warm up your body before you play ball. You need to warm up both physically and mentally.

Playing badminton is a strenuous exercise, which consumes a lot of physical strength. People usually exercise after a day's work. Before exercise, the body, internal organs and psychology should be fully prepared and adjusted. At this time, the cardiopulmonary level is relatively low and the muscle viscosity is also high.

If you play ball without warming up, your movements are stiff, uncoordinated and your energy is not concentrated, which is easy to cause sports injuries, muscle strain, ankle sprain and knee joint strain. Amateurs often have calf strain, Achilles tendon tear, shoulder, elbow and wrist joint injuries when clapping their hands. In addition, not doing warm-up activities is also a kind of pressure on the heart, which may lead to serious accidents.
