Abstract

Biorhythmological features and parameters of vegetative status of morning chronotype operators demonstrate a significant mutual influence. In particular, the value of cardiorespiratory ratio and final result of Ostberg – Stepanova test have a strong direct correlation (rs = 0,754), which represents high ability to adapt to stress in clearly defined «larks». Microhemodynamic parameters for morning and evening chronotype operators also have a pronounced biorhythmological determination. Clearly defined «larks» are characterized by a decrease in the contribution of the cardiac compensatory mechanism to the promotion of blood through the capillaries. At the same time, weakly defined «owls» have higher frequency values in the vasomotor and endothelial spectra.

Keywords

operator activity, chronotype of operators, vegetative status, spectral analysis of heart rate, microhemodynamics, microcirculation in skin vessels, professional selection of operators.
