Extreme long-term sports, such as cross-country running, marathon, long-distance swimming, cycling, mountain climbing, etc. Although I have been doing aerobic exercise, it costs a lot because of its long duration! After this type of exercise, you can't rest immediately. You need to walk slowly for a few minutes (you can't sit down and rest immediately). If you feel tired after exercise, squat down or sit down to rest. In fact, this is a wrong method. If you squat down and rest immediately after exercise, it will hinder the blood return of lower limbs, affect blood circulation, deepen physical fatigue and easily lead to edema. After the crucible moves, the breathing rhythm should be adjusted.

First of all, don't stop resting right away. Adjust slowly and walk slowly. Remember not to drink water immediately, so that your body can recover. After fitness, you can sit down and rest in about ten minutes. This will hinder the blood circulation of lower limbs, affect the blood return and aggravate physical fatigue. For people who don't exercise regularly, the pain after exercise will be more obvious, so don't sit down and rest now, which will affect blood circulation and lead to excessive lactic acid secretion, and it is easier to aggravate muscle fatigue after strenuous exercise. You should walk slowly for ten minutes and take a deep breath to help your muscles get rid of fatigue as soon as possible.

This is a common misunderstanding. Our grandparents told us that taking a hot bath after physical fatigue can delay fatigue. In fact, there is an essential difference between the two. After fitness, the muscle fibers of the body are in a state of ultrastructural changes (muscle fibers are damaged and inflamed), which is a benign reaction of the body. Due to the ultrastructural changes, only muscle fibers can recover excessively. Sweat produced by exercise will consume water in the body, which will have a negative impact on sports performance and delay recovery. At this point, we must emphasize the method of replenishing water. If you weigh yourself before and after exercise and lose weight after exercise, then losing weight is the amount of water and liquid lost in your body during exercise. The decrement is multiplied by 1.25 or1.5,5,5.

During exercise, the nerve center is in a highly active state. Under his influence, the parasympathetic nervous system, which manages visceral activities, will strengthen the inhibition of digestive system activities. At the same time, all the blood in the body is redistributed during exercise. Most of the blood is concentrated in the limbs and the digestive organs are weak.
