Features of the Structure of Variability of the Cardiorhythm of Residents of Tajikistan Depending on the Type of Vegetative Regulation

Abstract

The results of a study of the level of functionality of the regulatory systems of the inhabitants of Tajikistan are presented. A comparative analysis of the indicators of variational cardiointervalometry in men and women of Tajiks is given. The aim of the study was to study the functional state of autonomic regulation in Tajiks, depending on the state of activity such as the autonomic nervous system. We examined 233 people aged 18 to 40 years. Based on the values of the stress index, variational magnitude, and the total power of the spectrum from the entire population under study, three groups of individuals were formed: vagotonics, normotonics, and sympathotonics. Indicators of variational cardiointervalometry were recorded using a psychophysiological testing device UPFT-1/30 “Psychophysiologist” in the sitting position with a cycle of 128 cardiointervals for 5 minutes. The indicators of variational cardiointervalometry in men are higher compared to women. Differences in the activity of regulatory systems and assessment of the functional state in men are significantly different from indicators of women. Significant differences are noticeable only in the group of vagotonics. Both among men and among women, a greater number of subjects with a hyperactivity reaction were revealed. In 37 % of the examined, regardless of gender, the state of the optimal working voltage of the body was revealed. It has been established that sympathotonics dominate among women, this may indicate lower adaptive abilities of women, which is a sign of greater energy expenditures during adaptation, and normotonics dominate among men. When compared with indicators of the functioning of the body of men and women, features of the deterioration of blood circulation regulation and a decrease in the level of physiological health in vagotonic men were revealed.
