ADAPTIVE CHEMOREFLECTORY MECHANISMS RESPONDING TO EXTREME FACTORS

Abstract

An analysis of adaptive chemoreflectory mechanisms responding of extreme factors opens prospects for understanding of a role of a phenotype in this process, and also for search of new methods of the forecast and diagnostics. We analysed individual-typological variability of hypoxic tolerance and muscular working capacity at healthy people with various kinds of habitual sports activity. It is established, that formatting of new neuro-visceral interactions which occurs under the influence of individual training process, is reflected in reactivity of cardiovascular and respiratory systems in response to hypoxia. Adaptive strategy produces changes in systemic response to hypoxia which correlates with aerobic work capacity and EEG activity of a brain at sportsmen of different specializations. Individually-typological characteristics of sportsmen (typology of nervous system) also mediate EEG response to hypoxia, but they can be modified by the influence of phenotypic adaptive mechanisms (aerobic, anaerobic or mixed type of individual training process). The obtained results testify, that sports loadings forms specific adjustment of mechanisms of chemoreflectory regulation of cardiovascular and respiratory systems.
