ОЦЕНКА АДАПТАЦИИ К ЭКСТРЕМАЛЬНОМУ КЛИМАТУ ПРЕДСТАВИТЕЛЕЙ АЗИАТСКИХ ПОПУЛЯЦИЙ

Abstract

The article analyzes the results of studies of the compensatory-adaptive and reserve capabilities of the body in representatives of the Asian populations of Yakuts and Central Asia in the extreme conditions of Yakutia. It is commonly known that Yakutia is characterized by a sharply continental climate, which causes adaptive changes in the basic systems of the body. Anthropometric indicators were studied, such as body length, weight, waist circumference, hips circumference, the state of the cardiovascular system in terms of average blood pressure, heart rate and body mass index. To assess the compensatory-adaptive capabilities of the body, the Kerdo index was calculated to assess the state of autonomic regulation based on the values of pulse and diastolic pressure according to the formula, the index of functional changes according to the method of R. M. Baevsky et al. (1979) in points, which shows the degree of adaptability of the body, the state of functional reserves and can serve as a kind of prognosis of health. Statistical processing of the material was carried out using the IBM SPSS STATISTICS 21.0 software package. To assess the relationship between the studied parameters, a non-parametric correlation analysis according to Spearman and Pearson was carried out. The study revealed that a greater number of overweight and obese individuals were found among the indigenous population compared with natives of the southern regions. The average waist circumference was also statistically significantly higher among the indigenous group. The study of the main parameters of the cardiovascular system showed that they allow us to identify the spectrum of adaptive and adaptive reactions of the body and have ethnic characteristics. Shifts in body mass index can be considered as one of the options for the violation of compensatory-adaptive mechanisms.
