What are the benefits of regular swimming?

Swimming is a very good sport. If you swim regularly, it will definitely be good for your body in many aspects, especially in summer. If you have time, you can take your family to swim. If you feel that your cardiopulmonary function is not good, or even feel that you are a little fat, and if you want to lose weight, you can do activities like swimming. So what are the benefits of swimming? Let me introduce them to you.

1. Enhance myocardial function

When people exercise in water, all organs are involved, which consumes a lot of energy and speeds up blood circulation to supply more nutrients to the exercise organs. The increased blood velocity increases the load on the heart, causing it to beat faster and contract more forcefully. People who swim regularly have excellent heart function. The average person's heart rate is 70-80 beats per minute, and the stroke volume is 60-80 ml. People who swim regularly can reach a heart rate of 50-55 beats per minute. Many excellent swimmers can reach a heart rate of 38-46 beats per minute, with a stroke volume of 90-120 ml. When swimming, the action of water makes it easier for blood from the limbs to flow back to the heart, increasing the heart rate. Long-term swimming will significantly increase the motility of the heart, make the contraction stronger, increase the thickness and elasticity of the blood vessel walls, and increase the blood output per stroke. Therefore, swimming can develop a strong heart.

2. Enhance immunity

The water temperature of a swimming pool is usually between 26 and 28 degrees. Soaking in water dissipates heat quickly and consumes a lot of energy. In order to replenish the heat dissipated by the body as quickly as possible to meet the needs of cold and heat balance, the nervous system responds quickly, speeding up the body's metabolism, enhancing the body's ability to adapt to the outside world, and resisting the cold. People who regularly participate in winter swimming are less likely to catch colds due to improved body temperature regulation function. It can also improve the body's endocrine function and increase pituitary gland function, thereby improving resistance and immunity to diseases.

3. Weight loss

When swimming, the body is directly immersed in water. Water not only has great resistance, but also has very good thermal conductivity and dissipates heat quickly, thus consuming more calories. Just like a freshly boiled egg, the cooling speed in the air is much slower than that in cold water. Experiments have shown that the calories consumed by a person running in a standard swimming pool for 20 minutes is equivalent to running at the same speed for 1 hour on land. The calories consumed by staying in 14-degree water for 1 minute are as high as 100 kcal, which is equivalent to the heat dissipated in the air at the same temperature for 1 hour. It can be seen that exercising in water can help many people who want to lose weight achieve twice the result with half the effort. Therefore, swimming is one of the most effective exercises to maintain body shape.

More and more people are beginning to like sports like swimming. In fact, swimming can enhance the body's resistance, and at the same time, it can consume excess fat as soon as possible, and it can also have a good weight loss effect. If you can't swim, you can sign up for a training class, or hire a swimming coach to learn. Appropriate participation in swimming programs is very good for your body.
