According to Dr. Tran Thi Minh Nguyet, water is very important for human health, especially for soccer players. If they want to maintain good physical condition and achieve high performance, players need to drink more water than usual, even when they do not feel thirsty.

Experts confirm that rehydration is very important for athletes, especially long-term sports that require endurance such as football. Such high-intensity physical activity will generate a large amount of heat, the body will sweat to cool itself to stabilize body temperature. If a player loses 1-2% of his weight due to dehydration, his performance will decrease.
Research shows that during competition or training, players easily lose water through sweat, leading to a loss of 1-2% of body weight. For example, an athlete weighing 60 kg can lose 2% of their weight, or about 1.2 kg.
The more athletes move, the more they sweat, and the more water they lose. Therefore, it is important to always pay attention to preventing dehydration in athletes by drinking enough water before, during, and after training or competition. Athletes should not let their bodies become dehydrated because it takes many hours to restore the body's water balance.
In addition to water, sweat also contains electrolytes such as sodium, chlorine, calcium, potassium, magnesium... If you do not replenish enough water and electrolytes, it will lead to cramps, fatigue, rapid heartbeat, fainting, and even life-threatening cardiovascular collapse.
Doctors recommend that each player should drink 400 to 600 ml of water within an hour before a match or practice. During the match, you should drink several times, 150 to 200 ml each time, about 15 to 20 minutes apart depending on the level of sweating. After the match ends, you should drink immediately to compensate for the amount of water lost through sweat.Athletes lose one kilogram of weight and must compensate with one liter of water.
