title: [Age-related changes in the heart rate variability and hemodynamics shown by aboriginals in dependence on the leading type of vegetative nervous regulation].
abstract: We examined native minority adolescents (aborigines) to study somatometric and cardiohemodynamic characteristics in dependence on the leading type of vegetative nervous system. As result from the study, the age-related morphofunctional changes observed during the examined period of ontogenesis can be considered as heterochronic. Of note that, the hopping periods which occur in changes of somatometric and heart rate variability indices, can differ in dependence on the prevailing type of vegetative nervous system. Found that, the most number of reliable changes in vegetative nervous regulation is typical for vagotonic people at the age of 15, compared to the earlier ages. Apparently, this characterizes the conversion to decrease in activity of parasympathetic and increase in sympathetic component of vegetative regulation experienced by vagotonic examinees in the mentioned period. As regards normo- and sympathotonic examinees, no pronounced age-related change was found at the age of 13-17.
