During strenuous exercise or endurance exercise, heat production in the body increases, and sweating is the main way to dissipate heat. 98% to 99% of sweat is water, and the rest is mainly inorganic salts such as potassium, sodium, calcium and magnesium. After sweating a lot, it is necessary to replenish water in time, otherwise it will not only lead to fatigue and athletes' thermoregulation disorder, but also lead to the accumulation of acidic metabolites, which will lead to fatigue and the decline of sports ability. Athletes who feel tired may lack inorganic salts, which is manifested by the lack of potassium and magnesium in muscle cells.

Studies have shown that magnesium can promote glycogen decomposition, accelerate energy metabolism and improve sports performance. When magnesium is deficient, glucose produces lactic acid through anaerobic glycolysis, which causes muscle aches and spasms. Magnesium helps cells maintain aerobic oxidation and reduce the production of lactic acid, even during strenuous exercise. Magnesium is necessary for potassium to enter cells and calcium to enter and leave cells. Supplementing magnesium salt can avoid electrolyte imbalance caused by excessive sweating. In addition, magnesium and calcium are responsible for producing high-energy phosphorylates, such as adenosine triphosphate, which is necessary for muscle exercise. Therefore, you should drink alkaline drinks with sugar content less than 5% and inorganic salts such as potassium, sodium, calcium and magnesium during exercise, especially for athletes. Generally, minerals are removed from pure water, so it is not advisable to drink pure water alone during exercise.

What to eat after swimming?

Swimming is a sport that consumes a lot of energy. Because all parts of the body are rubbing against water during exercise, it is relatively safe to be protected by water during exercise, so the physical energy consumed is relatively large. Be sure to warm up and replenish energy before exercise. Be careful not to eat high-calorie things after swimming.

If you swim at night, you'd better eat something for dinner. Things on the list, such as boiled vegetables, are commonly known as mala Tang. Note that it is best to eat a banana just after swimming, so that the fruit that not only supplements calories but also does not gain weight is a convenient choice! ! !

You need to replenish water immediately after swimming. (Don't tell me you are full in the swimming pool: p) Hehe, drinking water after high physical exertion can replenish lost water and relieve hunger before eating, so it is also a good way.

You should try to use all these methods. It's all my experience. Think about it, swimming consumes so many calories. If you go out to eat m, you can earn back a pack of French fries. It's too worthless. For the sake of your health, you'd better exercise restraint. If all my friends want to go, I suggest they eat hot pot. Hehe, you can eat more vegetables. Hehe, you might as well try.
