Swimming is good for health. Supplement: sports
Swimming is a combination of water bath, air bath and sunbathing. It is not only a favorite sport for teenagers.
It is also a simple physical activity suitable for men, women and children. In a healthy sense, regular swimming and exercise can enhance the function of internal organs. When people swim in the water, they have to bear some pressure from the water, especially when inhaling.
To enlarge your chest, you must resist the pressure of water. Therefore, when inhaling, you must exert yourself. By swimming and breathing, you can exercise the inspiratory muscles and make the respiratory muscles strong and powerful. Because almost all muscle groups of the human body participate in activities when swimming, blood is needed to transport oxygen and nutrients to all muscle groups, which increases the burden on the heart, makes its movement more powerful, and makes the blood vessel wall thicker and more elastic. Thereby enhancing cardiovascular function. Therefore, the heart rate of swimmers is slower and stronger than that of ordinary people, about 40-60 beats per minute, and individual athletes may be less. People who have been engaged in swimming for a long time can also adapt to unusually rapid contraction of the myocardium. Swimming is carried out in water, and people's exercise in water consumes much more calories than on land, so it is necessary to supplement the heat emitted to resist cold water, so as to strengthen the metabolic process in the body and improve the body temperature regulation function to meet the needs of external temperature changes. In addition, insisting on swimming exercise can enhance the function of nervous system. In strength, speed, endurance, flexibility and other physical qualities have been significantly improved.
