Many who have seen the era of the USSR remember well how in physical education lessons and sections, teachers (coaches) forbade drinking water during classes and immediately after they ended. Nowadays, when there is widespread information about dehydration, it looks strange. But the meaning of this prohibition was also very important.
1. What is the reason
In fact, excessive consumption of water during active sports training (and it is now consumed in liters) can cause muscle cramps and spasms in an athlete. Of course, dehydration is bad for your health, but nothing happens in two hours. As for plain water, it can cause seizures, provoke trauma, such as rupture of muscle tissue, and in special cases, lead to a violation of the heart activities.
Australian scientists from Edith Cowan University in the course of their research have identified some pattern. According to the results of the experiment, it became clear that water solves the issue of dehydration, but creates the risk of seizures.
2. What happens to the body in reality
During training, an athlete loses a lot of electrolytes, which contain minerals, and primarily magnesium, potassium, chlorine and sodium. Drinking a lot of plain water will improve the hematocrit and the loss of electrolytes will accelerate. During the study, one group of participants drank special drinks for athletes during training, and the second group drank water. Problems with health and well-being were not observed in the first group.
As a result, Soviet athletes, who were allowed to drink and eat food only after the end of the training process, were practically not familiar with convulsive syndrome. Plus, they ate well. Their diet has always been potatoes, which are high in potassium, and salt is a source of sodium.
Modern athletes are often "on dry". Their diet lacks not only potatoes, but also buckwheat, bananas, salt. Accordingly, the amount of minerals is not replenished, which leads to strong convulsive activity. Naturally, there are special drinks enriched with minerals, but they are rarely consumed by anyone.

It turns out that Soviet athletes not only lost the complex of minerals, but also restored it in a timely manner and did not suffer from dehydration. Nowadays, no one is faced with the problem of dehydration, but many suffer from seizures and spasms.
