Abstract

The work includes the results of the research on morphofunctional parameters of the teenagers aged 15–18 of indigenous small peoples of the North. The anthropometric measurements are based on: body weight and length, depot fat composition (indirect calipermetry method). In addition, Quetelet index is calculated, the somatotype structure is determined according to the classification scheme of B. Heath and J. Carter. To assess the respiratory system functional state, the lungs’ vital capacity is assessed, together with the airway patency. To analyze the cardiovascular system, the heart rate, systolic, diastolic blood pressure is measured. To assess the functional state and adaptive resources of the organism, heart rate variability analysis is used. It has been revealed that the girls, in their age groups, are to some degree dominates the boys in the body density and the content of depot fat. Endomorphic indices – the degree of fat deposition – are also significantly higher in the girls. At the same time, all teenagers have developed musculoskeletal indicators. The analysis of respiratory system’s functional state has showed that all the measured parameters correspond to the norm, while the girls have a decrease in respiratory function when growing up. The study of the cardiovascular system parameters – heart rate, SBP and DBP – has witnessed their compliance with the age and sex norm in all the examinees. However, the analysis of heart rate variability has demonstrated a high Bayevsky tension index in most respondents, indicating the state of adaptive restructuring of the cardiovascular system and the state of stress. In this work the results of studying morphofuctional characteristics of the indigenous people teenagers at the age of 15-18 years old that live in the Sakha Republic (Yakutia, Russia) are presented. The children of the following nationalities such as the Yakuts, the Evenks and others have been studied.
