Peculiarities of the rate of adaptive restructuring of heart rate variability of natives of different generations living in the coastal and intracontinental climatic zones of the Magadan region

Abstract

Introduction: Currently, young Caucasian populations of different generations are living in the Magadan region (MR). The study of heart rate variability (HRV) in these samples will add to the modern understanding of the physiological mechanisms of adaptive restructures in those living in coastal and continental zones of the MR.

Aim: To study restructures of HRV in young Caucasians who were representatives of the zeroth, first, second, and third generations living in the coastal and continental zones of MR, with significant differences in the extremality of natural environmental factors.

Materials and methods: TThe study involved 870 young men aged 17–21 years. HRV parameters were analyzed using a Varikard device.

Results:  Compared with individuals of the same age living in the coastal zone, residents of the continental climatic zone were characterized by more evident predomination of the parasympathetic division of the autonomic nervous system. A tendency to the enhancement of the parasympathetic influence from the zeroth to subsequent generations was observed in both young men living in the coastal and continental zones.

Conclusion: The direction of adaptive shifts in the restructuring of HRV characteristics varied depending on the climatic zone where the examined individuals lived: in the continental climate of the MR, adaptive restructuring of HRV parameters occurs faster and already completed at the first generation in comparison with migrants, with no significant differences between representatives of the first and second generations. In young men living in coastal zones, restructures occur more slowly and continue upto the representatives of the third generation.
