The study features of changes in activity levels autonomic regulation parameters heart rate, stroke volume and blood pressure during active orthostatic test. The obtained results reflect the characteristics of transient hemodynamics players that characterize the specificity of adaptation to physical stress in this sport. It is shown that a decrease in the activity of the sympathetic division of the autonomic nervous system is not only alone but also in the orthostatic test. Along with this, in the regulation of stroke volume of heart and tone of the growing importance of large vessels suprasegmental level and humoral factors of regulation , both at rest and during the trial. Such activation may be one of the mechanisms to compensate for the loss of baroreflex sensitivity reactions and ensures consistency central hemodynamic parameters (heart rate, stroke volume and blood pressure) when changes in body position in space, reflecting the high level of postural stability athletes.
