Correlates of autonomous nervous and immune systems at intellectual exertion of medical students in conditions of combined action of environmental stressors

Abstract

In the process of research, an assessment of the indicators of the medical students adaptive capacity with different levels of physical fitness was made in conditions of the combined action of intellectual exertion and meteorological environmental factors. The functional state determination, the degree of tension of the regulatory systems and functional reserves were evaluated by calculating the Harkavy nonspecific reactivity index and the Bayevsky adaptation potential with the use of correlation analysis. Correlation analysis of these indexes revealed a significantly strong direct correlation, which was 0.72. Thereby, the Harkavy index (HI) at the second stage of the experiment in sharp fluctuations in meteorological environmental factors conditions reflected the level of adaptation mechanisms stress validly.
