FUNCTIONAL STATE OF THE VEGETATIVE NERVOUS SYSTEM IN 1-YEAR STUDENTS OF THE MEDICAL ACADEMY AND STUDENTS OF THE COLLEGE OF THE KYRGYZ STATE UNIVERSITY

Abstract

To study the characteristics of the vegetative nervous system to identify the adaptive capabilities of the 1-year students physicians and college students who study the humanities and technical professions. Materials and methods. To determine the tone and reactivity of the vegetative nervous system (VNS) of the subjects, a cardiointervalographic method (CIG) with an orthostatic probe was used. Results of the study. The parameters of the spectral analysis of the heart rhythm of 120 medical students aged 17 years and 160 students of the college aged 15–16 years were studied. To determine the reactivity of the VNS of the examinees, an orthostatic sample was used. It was revealed that the first-year medical students observed an increase in diastolic blood pressure for orthostasis, which indicates the vascular origin of the observed reaction. In the beginning of the sample, the vagotonic type prevails among the students of the college among the girls – the humanities (32%) and the youth of the technical direction of instruction (38%). Sympathicotonics dominate among young men (22%) and girls (18%) in humanitarian specializations. After the transition of the examinees to a vertical position, the predominance of the sympathetic nervous system responses in humanitarian students (65% boys and 47% girls respectively) of the direction of study was found. Research materials can be used in the preparation of textbooks, educational and methodological aids, special courses of physiological and pedagogical nature. Conclusion: A significant increase in diastolic blood pressure is observed in the group of first-year students of the medical academy, which indicates the vascular nature of the reaction to orthostasis. At the beginning of the orthostatic test, the vagotonic type prevails among the girls – the humanities (32%) and the youth of the technical direction (38%). Sympathicotonics dominate among young men (22%) and girls (18%) in humanitarian specializations. In studying the variability of the heart rate after the transition of the examinees to the vertical position, the prevalence of the sympathetic nervous system responses in students – humanitarians (65% boys and 47% girls, respectively) was found. The revealed pronounced type of sympathicotonia in students-humanitarian specializations may indicate low adaptive capacities, which are signs of high energy consumption of the body’s regulatory systems to maintain homeostasis, which indicates a higher “value” of adaptation to the loads.
