What are the benefits of swimming?

Swimming, as an aerobic exercise, is loved by more and more people because it burns fat quickly and at the same time has the advantages of strengthening the body. In the summer, exercising in the cool water is obviously much more comfortable than running under the scorching sun. Therefore, in summer, swimming is the exercise method chosen by many people. So, what are the benefits of swimming? Today, the editor will list the advantages of swimming.

1. Enhance myocardial function

All organs are involved when people exercise in water. As energy is consumed more, blood circulation also speeds up to supply more nutrients to the motor 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 7080 beats per minute, and the stroke volume is 6080 ml. People who swim regularly can have a heart rate of 5055 beats per minute. Many excellent swimmers can have a heart rate of 3846 beats per minute, with a stroke volume of up to 90120 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. Temporary 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. Strengthen lung function

The strength of lung function is determined by the strength of respiratory muscles, and breathing mainly depends on the lungs. Exercise is one of the effective ways to improve and increase lung capacity. It has been determined that when swimming, the chest of a person is subjected to a pressure of 1215 kg. The cold water soothes the tight muscles and makes breathing difficult, forcing the person to breathe hard and increase the depth of breathing so that the amount of oxygen inhaled can meet the body's needs. Swimming promotes the development of respiratory muscles, increases chest circumference, and lung capacity. It also opens more alveoli during inhalation, allowing for smoother ventilation, which is extremely beneficial to health.

It can be seen that the benefits of swimming are far more than we thought. It can not only enhance our cardiopulmonary capacity, but also enhance the coordination of our limbs, which is very good for both adults and children. The editor also recommends that you must warm up before swimming to avoid accidents.
