The article analyzes the problems of functioning of system of physical culture schoolchildren at the present stage, which is accompanied by low levels of health and physical fitness of the younger generation. A set of factors of negative influence, among which the greatest impact are: – significant amounts of teaching load, which does not correspond to the age and physiological features of organism of children; – lack of research-based pedagogical techniques that would have been obtained on the basis of indicators of heart rate, took into account geographical and social characteristics of the population. The possibility of increasing the efficiency of physical training of young men 15-17 years on the basis of research results and their functional training and analysis of relevant results. The obtained experimental data on indicators of heart rate at rest, after 20 sit-UPS in 30 seconds and the recovery period, the body of young men of a specified age after appropriate physical activity. The results of the study indicate the presence of negative dynamics of all indicators regardless of age, and changes in the latter two indicators have statistical significance. Thus, the results of heart rate at rest worsen during the entire period of study at 5,95%. Heart rate after exercise increased by more than 7%, and the recovery time – on of 17.67%. Thus, the identified changes can be characterized as the inexpediency of introduction of means of physical training, and the impact of puberty and active development of the musculoskeletal system of young men.
