This article presents a comparative analysis of the parameters of HRV students who are indigenous and non-indigenous residents of Yugra. Analysis was carried out carried out by multiple comparisons of three age subgroups and by multivariate analysis with the calculation of inter-cluster distances. The differences in the dynamics of age-related changes of Yugra schoolchildren reveals distinctive trend parameters of heart rate variability between indigenous and non-indigenous representatives of North. In particular, it revealed a higher adaptive capacity in Aboriginal representatives in comparison with the migrant population. The maximum divergence of parameters of the body boys observed in the older age group.

The current paper presents the difference in parameters of cardio-vascular system in the indigenous and newly arrived population of the UGRA. The problem of human body adaptation of newly arrived population compared with indigenous people (the Khanty) who have been living in Ugra for a long period of time is the main problem of human ecology. The solution of the problem is provided according to the theory of chaos – self-organization. The parameters of quas-iattractors and traditional stochastic parameters are compared. The effective calculation of matrixes of inter-quasi-attractor distances for estimation of such differences is shown.The authors have proved that chaotic parameters present peculiarities of human body in the Ugra population better than traditional stochastic parameters of cardio-respiratory system of a human living in the North.
