Girls learn to swim

In order to ensure their physical health, many people choose to exercise. There are many kinds of sports, and in the hot summer, many people like to go swimming, including many girls, who also appear in the swimming pool. In fact, there are many benefits for girls to learn swimming, such as enhancing myocardial function, improving resistance, losing weight, and improving body shape. Below I will introduce to you the specific benefits of girls learning swimming!

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. 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

Swimming to lose weight can avoid sports injuries of the lower limbs and waist. When exercising to lose weight on land, due to the heavy weight of obese people, the body (especially the lower limbs and waist) has to bear a large gravity load, which reduces exercise ability, makes people easily fatigued, greatly reduces the interest in weight loss exercises, and may damage the joints and bones of the lower limbs. Swimming is conducted in water, and a considerable portion of the obese person's weight is borne by the buoyancy of the water, which makes the lower limbs and waist feel much more relaxed, greatly reducing the risk of joint and bone injuries. 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 aerobic exercises for maintaining body shape.

4. Fitness

When swimming, people usually use the buoyancy of water to lie prone or supine in the water, relax and stretch the whole body, so that the body can develop comprehensively, symmetrically and harmoniously, and the muscle lines can be smooth. The resistance of water can increase the intensity of human exercise, but this intensity is different from equipment training on land. It is very gentle, and the intensity of training can be easily controlled within the aerobic range. It will not grow very stiff muscles, and can make the lines of the whole body smooth and beautiful.
