Many people know the importance of "warm-up", but they take the "cold body" after exercise lightly. Although the intense muscle contraction has stopped after strenuous exercise, the activity of internal organs is still at a high level. If you stop to rest immediately, such as sitting or lying still, the heart will quickly send blood to the limbs. At this point, the muscles of the limbs have stopped moving, and you can't pump blood back to the heart effectively, which is prone to dizziness, vomiting and even shock. In this way, not only the fatigue of the body is difficult to eliminate, but also it may cause harm to the body. Therefore, after the end of sports activities, we must carry out "cold body" that is, finishing activities. This helps to accelerate the elimination of metabolites, relax muscles in time, accelerate the recovery of fatigue, and effectively reduce muscle soreness after exercise. Now introduce several common "cold body" ways:

(1) Jogging or jogging is an active rest after exercise. Pace slowly with a relaxed pace and full spirit until you are comfortable breathing. Walking and jogging can also keep the temperature of muscle tissue above a certain level, so that muscles can maintain good ductility and elasticity. On this basis, stretching exercises are more conducive to muscle relaxation.

(2) Muscle traction can relax muscles in time, effectively prevent and relieve delayed muscle soreness (DOMS), strengthen the process of protein synthesis of skeletal muscle and accelerate the elimination of muscle fatigue. Drawing practice is mainly static drawing. When starting the static drawing exercise, the stretching range should be appropriate. In the process of continuous drawing, if you feel relaxed, you can gradually increase the stretching range until the maximum possible range. The length and repetition times of the drafting movement can be determined according to the intensity of the movement. Generally, the drafting time is about 30 seconds-1 minute, and the interval is 1 minute, and it is repeated 2 to 3 times. Proper kneading and shaking after drafting is helpful to eliminate the discomfort caused by drafting.

(3) Personalized "cold body"

In fact, reading books or listening to professionals telling us all kinds of fitness things is always boring. In our "cold body" movement, we can also have our own elements, such as listening to soothing music while walking. There is also the need to relax the mind, because after exercise, the heart beats faster, and people's breathing frequency will also accelerate. At this time, you need to calm your emotions through self-suggestion. The suggested method is to find a quiet place, sit still, close your eyes and take a deep breath. At the same time, I can imply that I am at the lake, blowing the wind and soaking my feet in the lake. After half a minute, people will gradually calm down.
