Topicality. Determination of the level of efficiency of physical culture classes according to the study of catecholamine excretion to find out the role of physical activity in the activity of a certain level of integration of the neuroendocrine system in the body's adaptive processes.
Objectives of the study: to study the content of catecholamines in the daily urine of groups of people who were engaged and those who were not engaged in physical culture by chromatographic method – to compare the results of the study to substantiate the relevance of research on the regularities of sympatho-adrenal system responses to various environmental factors.
Research results.. Changes in the content of adrenaline, including its reduction in the urine of the main group in the dynamics and a slight increase in the content of dopamine in the urine compared with the control group testify of involving the exchange of catecholamines in the regulatory mechanisms of various physiological processes. A statistically significant higher level of adrenaline excretion and a decrease in the excretion of other catecholamines in the urine of the main group of subjects, and a better overall subjective state of the main group indicates a significant effect of physical culture on the establishment of neurotransmitter balance, possibly due to activation of neurohormone synthesis.
Conclusions. Physical training and sufficient motor activity have a positive effect on the production and excretion of catecholamines and the establishment of an optimal neurotransmitter balance to improve adaptive processes in the human body
