Chaotic dynamics of cardio intervals in three age groups of indigenous and nonindigenous populations of Ugra

Abstract

The issue of the life expectancy of indigenous and nonindigenous populations of the northern territories in the Russian Federation is analyzed in terms of economic growth and industrial development of the northern territories. The importance of prolonging the period of active working age of nonindigenous population of Khanty-Mansiysk Autonomous Okrug–Ugra and Yamalo-Nenetsky Autonomous Okrug is increasing. Four possible directions are presented for prolongation of the active life of the nonindigenous population. The problem of comparative dynamics of age-related changes in the cardiovascular system in three specific age groups of female indigenous and nonindigenous population is considered. A decrease in the volume of quasi-attractors in the phase space of states is equivalent to adding exercise stress, which is typical of normal aging. We offer a mathematical pattern to reduce these volumes in assessing the dynamics of human aging in the north.
