Estimation of psychophysiological status of students adapting in the subarctic region

Abstract

The study was conducted on the basis of the Medical Institute NEFU. 44 volunteers from the university students between 18 and 23 years were the object of the study. All surveyed were male. We studied the features of psychophysiological state at forming adaptive reactions of the students M.K. Ammosov NEFU from countries with a hot climate (the main group). The control group consisted of students, representatives of indigenous ethnic groups (Yakuts, Evens). It was revealed that at adaptation to extreme subarctic climate in foreign students there are marked a shift in the balance towards the activation of the sympathetic part of the vegetative nervous system, moderate and high levels of personal anxiety, not accompanied by the perception of the majority of situations as threatening and the development of anxiety. On Harvard step-test graduation index in both groups there were no persons with the assessment of physical performance “excellent”. By indicators of heart rate variability in the main group the activity of stress-limiting systems dominated, whereas in the control – optimal adaptation indicators. It was found that the adaptive possibilities of the body of persons in the control group, estimated by the capacity of slow and fast waves, are characterized by low levels of mobilizing and reduction potential, in the main - a moderate level.
