Recently a population of the residents born in the north within their 1st – 3rd generations being Europeans, is forming in Russia’s northeast. Besides, an Aboriginal population also resides in the region. It is presented by ethnic Chukchee and Evens. The Aborigines of the north are characterized by having some morphofunctional parameters that are fixed at genetic levels, in contrast to the north-born Europeans whose adaptation changes are mainly determined by a phenotype. To study physiological profiles of the adaptive changes in the north-born Europeans in comparison with the Aborigines, we examined young male people aged 17-21 (n = 350) being residents of Magadan region that is situated within the range of 60-64° NL and 145-162° EL. The average year temperature in the region is 7° C below zero. The examined people underwent general measurements of registering their heart rate R-R intervals at rest and at orthostatic exercise as recommended by the European and North America’s Association of Cardiologists. Based on the values of the heart rate variability, its statistical and spectral-wave characteristics were calculated. The results found no reliable difference between the heart rate variability indices of the north-born Europeans and the Aborigines at rest. However, during the orthostatic test that can reveal cardiovascular system’s reserves, a reliable difference between the examined populations was observed in the following indices: mode (Mo), variation range (MxDMn), standard deviation (SDNN), stress index (SI), total power of the spectrum of the heart rate frequencies (PT) as well as its low (HF) and very low (VLF) components. Of note that, the heart rate structure difference suggested more pronounced tension of regulatory mechanisms in the Aborigines compared to the Europeans, at the background of activation in the sympathetic vegetative nervous system and lower functional reserves of cardiohemodynamics. Found that, only two of the 11 values of the external respiration function registered at rest, showed a reliable difference. The Aborigines demonstrated the lung vital capacity and the volume of the expired air per second, respectively, 570 ml and 410 ml less than those of the Europeans. Thus, we can suggest that the north-born Europeans and the Aborigines of Russia’s north have no difference in the series of cardiorespiration parameters. This fact enables to say of the forming of a convergent type of adaptation in the modern population of Russia’s north. In the meantime, the Aborigines proved to have reliably lower functional reserves in some physiological systems as compared to those of the European north-born residents.
