Bernada V. Valuation of physiological mechanisms of adjust-ability of cardiovascular system activity of a hu-man being to mental loading

The competitor examined complex investigations of hemodynamic supply of mental loading of 260 healthy young people depending on peculiarity of autonomous regulations, psychological status, individual and typological peculiarities of the upper nervous action. It was established that people having vagatonic and eutonic types of vegetative regulation display most ediquate hemodynamic reactions on metal loading. We also found out lesser degree of activation of sympathetic section of ANS (autonomous nervous system) and its reseprocal cor-relation with sympathetic link. We believe that it is neces-sary to consider the displacement of regulatory activity to the side of its super segmental levels as an unfavourable reaction on the side of ANS under hemodynamic supply of mental loading. By comparison hemodynamic reactions on mental loading of people having different psychological features made it possible to establish the fact that combina-tion of introversion and intuition, visual and digital types of representative system and low level of common aggres-sion promotes high effectiveness and quality of mental activity. It was also found out that individual and typologi-cal data of the upper nervous activity essentially influences hemodynamic reactions during mental loading. At the same time changes of the date of central hemodynamics are closely connected with the power of nervous processes. And the data of myocard are connected with the functional mobility of nervous processes.
