Special preparations should be made for the parts that are heavily burdened and easily injured during training. The time between the end of warm-up activities and the start of training should not exceed four minutes. When the interval is too long or other parts change, special preparation activities should be carried out.

For example, before running and jumping, we should focus on exercising muscles and joints, especially leg muscles, knees and ankles that are easily injured.

Through warm-up activities, the viscosity of muscles and ligaments can be reduced, their elasticity and ductility can be enhanced, and the range of joint activities can be increased, so that the human body can be prepared to change from a relatively static state to a tense state of exercise, and sports injuries can be effectively prevented.

2. Be sure to carefully check whether the sports ground, equipment and equipment are safe before fitness.

3. Use the muscle efficacy patch in the fragile part to regulate the nerve to restore its original function and protect the muscle.
