What is the prime time for swimming?


More and more people include swimming in their fitness programs. However, many people often spend a few hours in the water as soon as they enter the pool. In fact, this is wrong. The prime time for swimming should be 40 minutes.

40 minutes of exercise can not only achieve a certain amount of exercise, but also not make people too tired. When swimming, glycogen stored in human muscles and liver is the main energy supply. In the first 20 minutes, the body mainly relies on the heat provided by glycogen to maintain physical fitness; after 20 minutes, the body will break down fat to provide energy. Therefore, for the purpose of weight loss, 40 minutes can play the role of weight loss.

In addition, the water in the indoor swimming pool contains elemental chlorine. When chlorine interacts with sweat, nitrogen trichloride is formed, which can easily damage eyes and throat. A new research result from the United States shows that frequent entry and exit of swimming pools with a lot of elemental chlorine will cause injuries to the body far beyond the benefits of swimming. However, controlling the swimming time can avoid such injuries.

Finally, I would like to remind everyone that since water is a good thermal conductor, the thermal conductivity is 23 times that of air, and the human body dissipates heat in water 25 times faster than in air. If a person is immersed in water for too long and the body temperature drops too quickly, there will be blushing of the lips, pale skin, and chills.

Therefore, beginners should not spend too long in the water each time. Generally speaking, 10-15 minutes is the most suitable. Before going into the water, you should do warm-up exercises first, and then shower the body with cold water, and wait until the body adapts to the water temperature before going into the water.
