In football, the foot plays the most important role. In the competition, athletes must adopt the actions allowed by the rules, such as running, turning and jumping. These movements are very exhausting and the game time is particularly long. In such strenuous exercise, athletes will keep sweating, so it is especially necessary to replenish water, and quickly replenish water during the break to cope with the next competition.
Basically, no one will go out to exercise after eating, but will wait for some time to digest, because the stomach will swell and exercise will be uncomfortable. In fact, it is the same for football players not to drink water at rest. Drinking water before running will make most people feel uncomfortable, not to mention strenuous exercise like football. There is also that drinking water directly after strenuous exercise will hurt your stomach. What can become a football player is very good physical fitness. If they have gastrointestinal diseases, their careers will be ruined in advance.
Then, some people will say: since there are so many stresses, why do football players drink saliva at rest and then spit it out? Just don't drink. This is because after strenuous exercise, athletes will be thirsty. Athletes use this way to moisten their tongues and mouths. Moreover, this kind of water is not our common mineral water, but the carbohydrate provided by the sphere.
Many people ask, can this really replenish water? If it is true, why do we usually drink so much water? Experts say that this is only a psychological suggestion and can play a short-term role. In fact, all football players have experienced exercises that ordinary people have never experienced. Their endurance and water loss are different from ordinary people. They also know their physical condition very well, so there will be no excessive water shortage. If they really feel uncomfortable, they will say hello to the coach in advance.
