1, life skills Swimming is an essential life skill, and life is inseparable from water, so swimming is necessary for survival.
2, the role of weight loss Water not only has great resistance, but also directly soaks in the water when swimming. Moreover, the thermal conductivity is also good and the heat dissipation speed is fast, so a lot of heat is consumed.
3, enhance the resistance to heat dissipation in the water, the water temperature of the swimming pool is often 26 degrees to 28 degrees. High energy consumption. 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.
4, skin care effect When people swim, the water washes the skin, sweat glands and fat glands, which greatly reduces the comfort of salt in sweat to the skin, promotes blood circulation, and makes the skin smooth and elastic. In addition, when swimming outdoors, the body is exposed to water, sunshine and fresh air for a long time, which is more conducive to the health of the skin.
5. Children's swimming is more conducive to growing taller. This is because the buoyancy in the water greatly reduces their own gravity, which is not oppressed by gravity and is more conducive to physical growth.
Every summer, many people go swimming and learn to swim, but disadvantages always happen. On the one hand, in order to cool down, many people have more accidents in swimming. On the other hand, it is a pleasure to swim in bikini in hot summer, so many people can swim and learn to swim now. Swimming is also very beneficial.
Swimming:
Swimming is a skill that people float upward under the buoyancy of water and make their bodies move regularly in the water by virtue of buoyancy.
From 65438 to the 1960s, swimming activities in many parts of Britain were quite active. 1828, Britain built the first indoor swimming pool at Liverpool George Pier. By the 1930s, this kind of swimming pool appeared in major cities in Britain. 1837, the first swimming organization was established in London, England, and held the earliest swimming competition in Britain. 1896, swimming was listed as an Olympic event.
The highest organization for swimming is the International Swimming Federation, headquartered in Lausanne, Switzerland. 1908 was proposed by the swimming associations of Belgium, Denmark, Finland, France, Germany, Britain, Hungary and Sweden.
