INFLUENCE OF SWIMMING IN FASTERS ON THE ORGANISM OF PUPILS OF GENERAL EDUCATIONAL ORGANIZATIONS OF THE MO RF

Swimming in flippers, in comparison with other types of physical exercises, is distinguished by its characteristic features, which boil down to the following - in the process of swimming, the athlete performs movements when he is in the aquatic environment, excluding any solid support. Due to this position of the body, the motor abilities of a person increase, which improves their development. In this case, the mobility of almost all parts of the body increases, and the organs and systems of the body develop and strengthen. In adolescents, the difference in maximum oxygen consumption at different levels of fitness is less pronounced than in adults. Adolescents reach the maximum level of oxygen consumption faster, but cannot maintain it for a long time. The possibilities of anaerobic (oxygen-free) metabolism in adolescents are limited. The total energy expenditure for performing work of equal volume in adolescents is higher than in adults and is accompanied by the formation of a large oxygen debt and, accordingly, a large accumulation of lactic acid. In adolescents, blood sugar is reduced faster. Scuba diving is widely used as a means of hardening and preventing colds. Due to the increased heat transfer in water, the metabolism in the body is activated, energy consumption increases. This helps to achieve optimal weight, the optimal ratio of adipose and muscle tissue. Water pressure on the chest stimulates the development of respiratory muscles, mobility of the chest, increase its size, increase the vital capacity of the lungs. Swimming in fins harmoniously develops physical qualities - strength, agility, endurance. Tube breathing stimulates the development of the cardiovascular and respiratory systems.
