THE VEGETATIVE SUPPORT OF PURPOSEFUL ACTIVITY AND PERFOMANCE EFFICIENCY IN HEALTHY PEOPLE

Aim. The study of purposeful activity's autonomic maintenance and it's role in systemogenesis of unequal activity's efficiency in healthy people. Materials and Methods. 61 healthy persons were observed. The modeling of purposeful activity include Shulte test: the choice of numbers of different colors in ascending order. We recorded heart rate variability parameters and sympathetic skin evoked potentials before the Shulte test. The parameters of heart rate variability include analysis of cardio interval's dynamic range and spectral analysis characteristics. The heart rate variability parameters and sympathetic skin evoked potentials characteristics allowed us to evaluate sympathetic, parasympathetic, ergotropic and trophotropic regulative influences. Comparative analysis of characteristics by nonparametric methods, logit regression analysis, artificial neural networks modeling were performed. Results. We identify the heterogeneity of investigated group by the parameters of activity's efficacy. The high performance group is characterized by lower level of mistakes, intervals after and before mistake; low performance group has opposite characteristics. A study of vegetative maintenance of modeling behavior revealed higher activation of ergotropic and trophotropic mechanisms in high performance group of healthy people. We offer some prognostic models which predicts the performance efficiency on the basis of vegetative maintenance parameters. The parameters of cardiointerval's variability play the most important role in solution of classification task. The artificial neural networks models have higher classification abilities. Conclusion. The role of summary segmental and suprasegmental autonomic regulation influences in determination of system organization of high activity's efficiency was established. The high activity's performance is associated with activation of the suprasegmental ergotropic and trophotropic mechanisms.
