Experiments show that the heat consumed by staying in 12 degree water for 4 minutes is equivalent to the heat consumed by land at 1 hour at the same temperature. It can be seen that under the same time and intensity, the heat consumed in water is dozens of times that of land. Underwater resistance forces the body to convert energy, and there is nowhere to hide fat in the body.
The energy consumed by swimming comes from sugar and fat stored in the body, and lactic acid anaerobic is the only form of energy conversion in the body. Swimming promotes the metabolic speed of the new city and drives the whole body muscles to get exercise.
By adjusting the ratio of fast and slow muscles, the ability of myocardial blood supply, lung ventilation and neuromuscular activation, the body can adapt to underwater sports.
During this period, the back, chest, abdomen, buttocks and legs will be exercised at the same time. And this metabolic rate can last for a while after you leave the water, so swimming is an ideal way to lose weight. However, some people will complain.
