Introduction. The aim of this work is to determine the presence of adaptive shift processes and secular trend in modern groups of the Tuvan rural population compared with the data obtained in previous studies in the 1970s of the XX century. Materials and methods. The material for the study was the results of surveys of 538 first-year tuvan students (187 boys and 351 girls). Based on the obtained morphological and functional indicators, a comparative assessment of the adaptive capabilities of students in 9 regions of the Republic of Tyva, differing in variations in the thermal and humidity conditions, as well as in altitude, was carried out. Anthropometric measurements were taken according to the standard procedure and used to determine morphological and functional parameters (length and body weight, chest circumference, Quetelet index and stenia index, heart rate, blood pressure). Intergroup differences in somatic characters and the state of the adaptive capabilities of the cardiovascular system were estimated. Results and discussion. The obtained data on the temporal dynamics of body length indicate significant adaptive shifts and the presence of a secular trend in all studied samples. The research results allowed us to determine insignificant intergroup differences in the variability of characteristics of male and female somatotypes in the examined modern young generation of Tuvans in different environmental conditions. In men, intergroup variability is more pronounced along the length of the body, and in women, by the circumference of the chest. Conclusion. It can be assumed that the increase in body length found in a number of populations in the modern population of Tyva is characteristic of most of the population of the republic. This indicates that the transformation of traditional culture and lifestyle has affected almost the entire Tuvan population and entailed significant changes in the adaptive characteristics of the indigenous population, and therefore in the state of health at all stages of ontogenesis. The changes in morphological status found at this stage are not associated with noticeable changes in the physiological parameters of the cardiovascular system in the same groups. The results obtained revealed a trend that manifests itself in higher adaptive reserves in girls compared with boys.
