How to drink water when riding in summer?
As the saying goes, women are made of water, but men are also made of water. In fact, the average water content of normal men is about 60%, women’s water content is 50%, and the water content of high-level athletes is close to 70% (because the water content of muscle is as high as 75% and the water content of fat is only 10%. ). Water is the most important component of blood. It can transport nutrients, oxygen, and hormones to cells and take away by-products of metabolism. It is also a key component of the human body temperature regulation mechanism. Water and electrolytes participate in the control of human osmotic pressure and maintain human body balance.
In sports, most people will experience dehydration, and dehydration will lead to a decrease in blood oxygen content, which will lead to a decline in exercise capacity. Moreover, during exercise, the human body runs under high load, and it must take away heat through the evaporation of a large amount of sweat. Therefore, how to correctly replenish water during exercise is a compulsory course for every sports enthusiast.
1: Don’t wait until you are thirsty to drink water
During exercise, it is almost impossible for people to take in enough water to maintain the body’s water balance. The loss of human body water during prolonged exercise will lead to higher plasma osmotic pressure. When the osmotic pressure sensor of the human hypothalamus detects that the blood state is hypertonic, that is, when we feel thirsty, our body has already lost as much as 1.5-2L of water, which means that the body is already in mild dehydration. That’s why we don’t drink water until we are thirsty during exercise.
Especially riding in a humid and hot summer environment, the body loses moisture faster, speeds up the body’s risk of dehydration, which will result in a gradual decrease in blood volume, reduced sweating, and a faster heart rate, leading to the early appearance of fatigue. There may also be life-threatening angina pectoris. Therefore, summer cycling to replenish water should not be ignored.
