Hygienic estimation of functional reserves and adaptive capabilities of students

In the article there are presented data on characteristics ofpeculiarities of the functional state of medical 1-6 years students of higher educational institutions. The results were obtained with the aid of variation pulsometry. Students were shown to have typical elevated tone of the sympathetic nervous system, especially for students of the 1^st, 3^rd, 5^th and 6^th courses, that is confirmed by the amplitude mode (AMo), characterizing the sympathetic activity of autonomous nervous system (ANS), which is an average of the students 1^st year accounted for 38.6 ± 1.89%, for students of the 3^rd course - 38.5 ± 1.72%, for students of the 5^th year (40.9 ± 3.25 %) and the students of 6^th course (46.7 ± 2.59%). There was determined the trend to the centralization of the heart rate control, as evidenced by a reduced proportion of high-frequency waves (HF) by 29.2% to 35.2%, exceeding by 3.6 to 14.4 times in waves of the very low frequency (VLF) relative to the average standard values; the high proportion of students from 41% to 52%, with a mismatch of the sympathetic and parasympathetic compartments of the autonomic nervous system in the regulation of biological processes of adaptation. For medical students of higher education institutions there are typical functional reserves reduced from 20.5 % to 97.6% and a decrease in the proportion of students with a satisfactory adaptation by 40.4% from the 1^st to the 6^th year.
