Does sweating a lot during exercise and fitness indicate poor physical fitness?

The hot summer is a time when people sweat profusely. There are many people who sweat whether they are eating or walking. Some people keep sweating even in an air-conditioned room. What's going on? Does excessive sweating indicate that one has a poor physical condition?

Many people believe that they should sweat profusely after exercise. If they don’t sweat, they cannot achieve the purpose of fitness. However, experts point out that the amount of sweating varies from person to person. First, sweat depends on the secretion of sweat glands, and the number of sweat glands not only varies by gender, but also by individual. Secondly, the amount of sweating also depends on the body fluid content. Some people have more body fluids, so they will sweat more than ordinary people during exercise. The amount of body fluid is determined by the body fat content. Because adipose tissue contains relatively less water, fat people have less body fluid than thin people. Although fat people sweat more during exercise, their ability to tolerate water loss is relatively poor. Therefore, fat people usually feel very tired soon after exercise.

Whether or not you drink water before exercise also affects sweating. If you drink a lot of water before exercise, it will lead to an increase in body fluids and increase the amount of sweating. Secondly, it also depends on the individual's physical fitness. People with strong physiques have healthier muscles and motor organs, and even if they do high-intensity exercise, it is effortless and they naturally sweat less. On the contrary, people with poor physical fitness will sweat profusely after a little activity.

Therefore, sweating a lot does not mean that the exercise effect is good. Some exercises that do not involve much sweating, such as walking and cycling, can also help prevent or reduce various chronic diseases.
