The decrease in orthostatic tolerance due to the deconditioning of cardiovascular system after space flight remains an urgent problem. The effect of longitudinal overloads on a short-arm human centrifuge (SAHC) is believed to be useful in preventing a decrease in orthostatic tolerance in astronauts after spaceflight through regular compensation of hydrostatic blood pressure, which is absent in microgravity. The analysis of adaptive reactions of the autonomic regulation system was carried out by analyzing heart rate variability, blood pressure was used to calculate hemodynamic parameters. These characteristics were analyzed in 6 male subjects (mean age 38 ± 7 (SD) years) during the protocol of training rotations on the SAHC and during a passive orthostatic test with foot support (tilt test). The nonparametric Wilcoxon criterion and Kendall’s rank correlation coefficient were used for statistical analysis. During training rotations, an increase in heart rate (HR), a weakening of high-frequency (HF) and a significant increase in low-frequency (LF) spectral components of the heart rate were observed, indicating the involvement of the sympatho-vagal system with a predominance of sympathetic regulation. It is shown that after a series of rotations on the SAHC, there is a smaller increase in HR in an upright posi tion during a tilt test, which indicates a decrease in excitability and reactivity of the sympathetic nervous system. There was also a decrease in the influence of suprasegmental (higher) autonomic centers on the regulation processes during orthostatic loading. This interval training protocol on the SAHC has a training effect and increases orthostatic stability.
