Quality Of Life For Schoolchildren Of 11-15 Years Old Depending On Their Level Of Physical Activity

The link between physical activity and children's health is known. Systematic studies of physical activity have shown that children who are engaged in physical exercise, have better physical and mental health. Low physical activity quickly leads to the development of a number of diseases, including obesity, coronary heart disease and metabolic syndrome. Sedentary behavior also contributes to the development of cognitive development and reduced child performance in school. According to the Russian statistics service in the country, there has been a deterioration in public health over the past 17 years, which is largely due to the computerization of schools and the introduction of new technologies in the educational process. The purpose of this study was a systematic review of the existing literature, which assessed the relationship between physical activity, sedentary behavior and their relationship to health and quality of life among schoolchildren 11-15 years old. The paper presents evidence that a higher level of physical activity and a decrease in the time of low activity lead to an increase in the quality of life and an improvement in the health of children and adolescents. In the future, it is necessary to revise Russian education in terms of increasing the physical activity of children and adolescents during extracurricular lessons. It becomes clear that besides this, active state propaganda of an active lifestyle among children and adolescents is necessary. All this in a complex can help to heal the younger generation in Russia.
