STATE OF REGULATORY MECHANISMS AND VASCULAR PARAMETERS OF FIRST YEAR STUDENTS OF NORTHERN UNIVERSITY WITH DIFFERENT LEVEL OF ADAPTATION RESERVES

Abstract

The study of the autonomic nervous system parameters and assessment of the adaptive reserves of the students’ organism allows to determine the key markers of changes in the functioning of the cardiovascular system at the prenosological level.
 Objective. To estimate regulatory mechanisms and state of vascular system of 1st year students depending on the level of adaptive reserves.
 Materials and methods. The total number of 245 freshmen of Surgut State Pedagogical University was examined: 18.3±0.33 years old on average. Heart rate variability at rest and during orthostatic test were measured by cardiointervalography (“VNS-spectrum”, Neurosoft company). We used hardware-software complex “Angioscan-01P” to assess the state of vascular bed. Statistical processing of the obtained data was performed using Statistica 10.0 program.
 Results. The results showed that during the active orthostatic test the number of intersex differences in the comparison groups significantly decreased in comparison with the background recording. The parameters describing the state of the vascular bed were the following: central pressure value, vascular age and stress level depending on the level of adaptive reserves.
 Conclusion. The adaptation reserves of the organism of 1st year students of the Northern HEI determine the regulatory features of male and female students as well as the value of vascular tone and the age of the vascular system.
