Over the last decades of the twentieth century, during the period of the scientific and technological revolution, the conditions and the labor process itself have changed dramatically. Automation of production, development of transport, improvement of living conditions have led to a decrease in physical activity of most people. In the human body, the neuro-reflex connections established by nature and strengthened in the process of hard work began to be disrupted. An urgent problem is the fight against physical inactivity, which arises due to limited mobility in many activities. Detraining of the motor system and functional systems of the human body, which provide muscular work with energy and plastic resources, creates the preconditions under which unexpected psycho-emotional effects on a person and even not very heavy physical activity cause a strong stress reaction. Social and medical measures do not give the expected effect in preserving people's health. Therefore, in modern society there is a need to develop one’s physical abilities through physical exercise. Physical training increases physical activity, stimulates intellectual processes, promotes health and longevity and is an integral part of a harmonious and fulfilling life. Swimming is a unique type of physical exercise and is one of the most popular sports, both in our country and abroad. It is one of the most effective means of strengthening human health and physical development, from the first months of life to old age.
