Relevance. Assessment of the functional state of the body is one of the leading tasks of physiology. The article deals with the analysis of the initial vegetative status of students with different levels of motor activity. Materials and Methods. Registration and analysis of the heart rate variability was carried out with the help of a modern complex electrophysiological laboratory «CONAN - 4.5». The heart activity of students engaged in physical culture within the educational process was evaluated on the basis of heart rate variability analysis. Results and Discussion. It was revealed that among the entire studied array of students (with the differentiation of the initial vegetative status calculated according to muscle tension index), «normotonics» are characterized by an optimal ratio between the parasympathetic and sympathetic divisions of the autonomic nervous system. At the same time, the value of the coefficient of physical activity in the studied group was determined at the level of 1.73±0.1. Conclusion. For vagotonics, the value of the triangular index was 2.5±0.2 conventional units (CU), which confirms the idea of an increase in the influence on the autonomic nervous system. The value for normotonics is 2.2±0.1 CU. This group was characterized by the balance between the sympathetic and parasympathetic parts of the autonomic nervous system. In sympathicotonics - 1.9±0.5 CU, which confirms the idea of increasing the influence of the sympathetic division of the autonomic nervous system. In hypersympathicotonics-1.1±0.4 CU. To ensure adequate functioning of the cardiovascular system and for normal adaptation to physical exertion in students, it is necessary to form a level of motor activity that quantitatively corresponds to a coefficient of physical activity of at least 1.75.
