To put it simply: taking part in regular exercise will make people feel great, in a good mood and energetic to complete various tasks and work. In addition, physical exercise also has the functions of preventing cardiovascular diseases, improving respiratory system function, improving digestive system function, improving nervous system function, reducing the risk of diabetes, preventing fractures, controlling weight, changing body shape and prolonging life. Physical exercise has a deep mass base, which is the most effective way to improve health and physical fitness, and can play a role in preventing and treating diseases. Sticking to scientific physical exercise can achieve the effect of "fitness, mental health and bodybuilding". What are the benefits of swimming to human health? Benefits:

1. Enhance myocardial function

When people move in water, all organs participate in it, which consumes a lot of energy and accelerates blood circulation, thus providing more nutrition for the moving organs. The acceleration of blood speed will increase the load on the heart, make the heart beat faster and contract strongly. People who swim regularly have excellent heart function. The average person's heart rate is 70-80 beats per minute, and the stroke output is 60-80 ml. The heart rate of frequent swimmers can reach 50-55 beats/min, and the heart rate of many excellent swimmers can reach 38-46 beats/min, and the stroke output is as high as 90- 120ml. When swimming, the role of water makes it easy for limb blood to flow back to the heart and accelerate the heart rate. Long-term swimming will obviously increase the activity of the heart, contract strongly, increase the thickness and elasticity of the blood vessel wall, and increase the stroke output. Therefore, swimming can exercise a strong heart.

enhance immunity

The water temperature in the swimming pool is often 26 to 28 degrees, so soaking in water dissipates heat quickly and consumes a lot of energy. In order to supplement the heat emitted by the body as soon as possible and meet the needs of cold and heat balance, the nervous system reacts quickly, accelerating the metabolism of the human body, enhancing the adaptability of the human body to the outside world and resisting the cold. People who often take part in winter swimming are not easy to catch a cold because of the improvement of body temperature regulation function, and can also improve the endocrine function of human body, especially the function of pituitary gland, thus improving the resistance and immunity to diseases.

lose weight

When swimming, the body is directly immersed in water, which not only has great resistance, but also has very good thermal conductivity and fast heat dissipation, so it consumes a lot of heat. Like a boiled egg, the cooling rate in air is far less than that in cold water. Experiments show that the heat consumed by a person running in a standard swimming pool for 20 minutes is equivalent to running at the same speed 1 hour on land, and the heat consumed by staying in water with 100 minutes is as high as 100 kcal, which is equivalent to being in air with the same temperature. It can be seen that water sports make many people who want to lose weight get twice the result with half the effort, so swimming is one of the most effective fitness exercises.

keep fit

When swimming, people usually use the buoyancy of water to lie prone or supine in the water, so that the whole body can be relaxed and stretched, so that the body can develop comprehensively, symmetrically and harmoniously, and the muscle lines can be smooth. Exercise in water reduces the impact of the ground on bones, reduces the probability of bone aging, and the joints are not easy to deform. The resistance of water can increase people's exercise intensity, but this kind of intensity is very soft, which is different from the equipment training on land. It is easy to control the training intensity in aerobic area, and it will not grow stiff muscle blocks, which can make the whole body lines smooth and beautiful.

5. Enhance lung function

Breathing mainly depends on the lungs, and the strength of lung function is determined by the strength of respiratory muscle function. Exercise is one of the effective means to improve and increase vital capacity. According to the measurement, when swimming, people's chest is under the pressure of 12- 15 kg. Cold water makes it difficult for people to breathe, forcing people to breathe hard, increasing the depth of breathing, and making the amount of oxygen inhaled meet the needs of the body. The average person's vital capacity is about 3200ml, and the breathing difference (the difference between the expansion and contraction of the chest circumference at the maximum inhalation and exhalation) is only 4-8 cm. The maximum oxygen uptake during strenuous exercise is 2.5-3 liters/minute, which is 10 times higher than that at rest. The swimmer's vital capacity can be as high as 4000-7000 ml, the breathing difference can reach 12- 15 cm, and the maximum oxygen uptake during strenuous exercise is 4.5-7.5 liters/minute, which is 20 times higher than that at rest. Swimming makes people develop respiratory muscles, increase chest circumference, increase vital capacity and open more alveoli when inhaling, which is very beneficial to health.

6. Skin care

When people swim, the water washes away the skin, sweat glands and fat glands, which plays a very good role in promoting blood circulation and makes the panel smooth and elastic. In addition, when moving in water, the influence of salt in sweat on the panel is greatly reduced. What are the benefits of organizing physical exercise and indoor sports for preschool children's health? Improve physical resistance and exercise will. Of course, the premise is to correctly guide children to participate, not to force them, otherwise it will be counterproductive.
