The impact of environmental factors, increasing the load for the human body, can lead to the depletion of its functional reserves. In the complex of compensatory-adaptive responses of the human body, the cardiorespiratory system as the most important element is an index of the adaptive capabilities of the organism. The degree of adaptation to environmental conditions and the state of human health are largely determined by the ethnic and gender variability of the norm and pathology. The functional condition of the cardiovascular system was assessed depending on the ethnic and gender referral of the inhabitants in regions of different natural and geographical zones of the Russian Federation. In men living in different regions, indices of the functional state of the cardiovascular system were basically established to have no significant differences. The exception is the difference in individual indices among Russian men living in the Republic of Altai, the Republic of Khakassia and the Volga region, as well as among Russian men and Kazakhs, Altaians and Kazakhs residing in the Altai Republic. Among women, statistically significant differences between indices of the functional state of the cardiovascular system are found more often in Russians, and Altai, Khakas and Kazakhs females. The hypokinetic type of auto-regulation of blood circulation was shown to be more common among Kazakhs males (78.1%) and females (64.8%), Khakas males (65.9%) and Russian women in the Republic of Khakassia (59.8%). The height above sea level and air temperature (p <0.05) were established to have the greatest influence on the intensity of compensatory-adaptive responses of the cardiovascular system in the number of natural-geographical and climatic factors of the regions of residence of the men and women surveyed.
