[The cardiovascular system during adaptation of students residing in a South-Siberian region].

The trend in adaptation processes was studied by the parameters of the cardiovascular system in Tuvian and Russian students during their study at a higher educational establishment. Not only the age- and sex-related features, but also ethnical features of students living under extreme climatic and geographic conditions were shown to affect education adaptation processes. Junior students of natural ethnicity had lower indices of cardiovascular system function than those of Russian ethnicity and a more adequate adaptive response to study.
