Preparing for exercise before exercise, stretching and relaxing after exercise, is a common thing for people who have participated in sports for a long time. But there are also some people who don't put these seemingly ordinary things in their eyes, and often cause sports injuries.
Not preparing for activities, not stretching and relaxing, for those who participate in sports, not only is not conducive to the movement of body functions before exercise, but also is not conducive to the relaxation of muscles after exercise. Therefore, it is very important to prepare for activities before participating in sports. In addition, stretching after exercise is also necessary. By stretching and relaxing, the heart rate, breathing, and muscle stress can be restored to normal levels before exercise, which can help prevent sports injuries and prevent muscle tension and congestion after exercise.
Expert advice: Under normal circumstances, the neck, shoulders, waist, knees, ankles and other parts should be fully active before exercise, such as well-known head movements, chest movements, body movements, leg presses, ankle joint movements. Etc., these parts can be effectively moved. At the same time, before participating in strenuous exercise, such as football, basketball and other projects, you can jog 500 to 800 meters, usually with a slight sweating, this can actively mobilize the body's various functions.
The stretching after exercise is relaxed. Generally, it can be performed by simpler hand movements, such as shoulder extension, which can effectively alleviate the discomfort of the shoulder part after playing. The practice is to cross the left hand over the body, the elbow is slightly bent, and the right hand is fixed. At the left elbow, then lean your left arm against your body until you feel the muscles of your shoulders are tight, then repeat the same movement. After running, the muscles of the legs are tight, which can be relieved by stretching the muscles in the back of the leg. After lying down, straighten the legs, lift one leg, and keep the knees straight and fixed, then move the legs to the legs. Pull the body direction as close as possible to the body and keep the legs alternate. In addition, the muscles can be massaged by massage, etc., if conditions permit.
