What do you need after exercise?

1. Can't rest immediately.

During strenuous exercise, people's heart beats faster, muscles and capillaries dilate, and blood is mostly concentrated in the muscles of limbs. Due to the strong contraction of limb muscles, a large amount of venous blood will quickly return to the heart, and the heart will send nutrient-rich arterial blood to the whole body. At this time, the blood circulation is extremely fast.

If you stop to rest immediately after strenuous exercise, there will be a lot of venous blood in your limbs, which will cause heart ischemia, hypotension and temporary cerebral ischemia, which will easily lead to palpitation, shortness of breath, dizziness, pallor, and even shock and fainting.

So do some relaxing activities after exercise, such as jogging, relaxing your legs and taking a deep breath. , make the blood circulation stable.

2. Don't drink too much

Often thirsty after strenuous exercise, many people are used to drinking boiled water or other drinks, but this will increase the burden on the stomach. On the one hand, drinking a lot of water will reduce the salt content in the blood, and sweating will make the salt lose more easily, thus reducing the osmotic pressure of cells, leading to sodium metabolism disorder and muscle spasm. On the other hand, after strenuous exercise, gastrointestinal blood is less, its function is poor, and its ability to absorb water is weak. Excessive water will penetrate into cells and intercellular substance, which will cause the increase of brain blood pressure, and make people have symptoms of water poisoning such as headache, nausea, blurred vision and slow heart rhythm.

So after strenuous exercise, although thirsty, don't drink too much water at a time. You should drink water by "drinking less many times". After exercise, you can take the following drinking methods.

Rinse your mouth with water to quench your thirst.

After exercise, although I feel thirsty, this thirst mainly comes from the increased breathing during exercise, the rapid evaporation of water, the reduction and thickening of saliva secretion, which makes the mucous membranes of the mouth, throat, respiratory tract and esophagus dry. At this point, you should rinse your mouth with clear water, moisten some mucous membranes in the respiratory tract, and then consciously restrain yourself, then the feeling of thirst will be alleviated.

② Add salt after sweating heavily.

Sweating a lot after exercise not only loses a lot of liquid, but also loses a lot of salt in the body, so the hydration should be mainly warm and light salt water; It is best to drink some 1% light salt water. If the mixing ratio is inconvenient, you can also buy alkaline sports drinks to replenish sodium and vitamins lost in the body in time, which can alleviate physical fatigue to some extent.

③ Control the drinking speed.

It is also necessary to replenish some water after exercise, but you can't drink enough at once, you should drink it several times. Generally, the quantity of drinking water at one time should not exceed 200ml, and the interval between drinking water at two times should be at least 15min. In addition, drink water slowly, not too fast.

3. Don't take a shower right away

Many people are in a good mood after exercise, so they immediately take a cold bath to dissipate heat, and often catch a cold soon. Because after exercise, in order to keep the body temperature constant, blood vessels on the skin surface dilate, sweat pores open and sweat increases. At this time, if you take a cold bath immediately, the blood vessels will contract immediately because of sudden stimulation, the resistance of blood circulation will increase, the burden on the heart will increase, and the body's resistance will decrease, and people will easily get sick.

If you take a hot bath at this time, it will continue to increase the blood flow of the skin. Excessive blood will flow into muscles and skin, leading to insufficient blood supply to the heart and brain, ranging from dizziness to collapse shock, which is easy to induce other chronic diseases. So after strenuous exercise, you must take a break before taking a shower.

4. Don't eat too much sugar

Some people think that eating sweets or sugar water after strenuous exercise can increase nutrition and supplement nutrition, which is good for the body. In fact, eating too many sweets after exercise will consume a lot of vitamin B 1 in the body, which will easily make people feel tired, lose appetite and affect the recovery of physical strength.

Therefore, it is best to eat some foods containing vitamin B 1 after exercise, such as liver, eggs and vegetables.

5. Don't drink to relieve fatigue.

Some people drink a lot of beer after exercise and think it is a way to relieve fatigue. In fact, after strenuous exercise, people's physical function is at a higher level. At this time, drinking alcohol will make the body absorb alcohol faster, and the damage to organs such as liver and stomach will be greater than usual. It can cause fatty liver, liver cirrhosis, gastric ulcer and other diseases for a long time. Moreover, drinking a lot after exercise will lead to a sharp increase in uric acid in the blood, leading to gout.

6. Avoid eating cold food

After strenuous exercise, I was sweating all over. Everyone likes to drink cold drinks and eat cold food immediately, which not only cools down, but also relieves summer heat. As we all know, this greed for temporary comfort is extremely harmful to the body. After strenuous exercise or strenuous physical labor, the whole body blood circulation is accelerated, the body temperature is increased, the blood supply to the gastrointestinal tract is temporarily reduced, and the gastrointestinal tract is at rest. If you eat cold food at this time, it will cause digestive dysfunction, sore throat, inflammation of digestive organs and other symptoms. It is best to use "heat" to relieve summer heat and quench thirst after exercise, such as drinking some hot tea and boiling water. In fact, eating cold drinks can only temporarily lower the temperature, but can't quench your thirst. You can't alternate hot and cold after exercise. Just after eating ice cream, you can drink hot coffee and hot milk. This sudden change in heat and cold will easily stimulate your teeth and cause dental diseases. Moreover, alternating hot and cold drinking is not good for the stomach, and it is more likely to cause digestive tract dysfunction.

If the contestants have enough time, they can have a rematch before the final. If there is not enough time, they can hold a rematch before the game. Only the finals will be held on the day of the competition, and the finals can also be held directly if there are few events. Similarly, other events such as high jump, long jump and throwing can also be eliminated, that is, several players with the worst performance are eliminated in each round (the number of participants is greater than 15). If the number of participants is small, you can directly select the top five to eight to enter the finals (the number of participants is less than 15). The results of the top three can be announced immediately during the sports meeting.
