It was found that 5-hour exposure did not change physiological responses to test workloads, when compared to the baseline studies. In the simulation studies, changes in acid-base equilibrium of venous blood were more significant than those of mixed capillary blood. The variations of the parameters under study reflected primarily the effect of hyperoxia on metabolic processes.

In both studies, lipid mobilization and utilization increased, which led to changes in the lipid spectrum: decrease of the concentration of LDL and, in the second trip, of VLDL and HDL3, and increase of the concentration of HDL2 and cholesterol HDL. In the second trip, lipids were most intensively utilized: lipolysis enhanced and free fatty acids declined. This was also indicated by an increase of the capillary-venous difference in terms of the total fraction of LDL and VLDL as well as free fatty acids. At the end of the second trip, the positive capillary-venous difference in terms of LDL and VLDL and, accordingly, the negative capillary-venous difference in terms of HDL2 and HDL3 increased.

It was found that: 1) the result of canal-otolith interaction was not directly related to the pattern of changes of otolith afferentation but was determined by the ratio of otolith afferent signals in the right and left labyrinths and, consequently, by the ratio of patterns of activities in the CNS paired structures that receive otolith afferentation; 2) the same result of interaction (enhancement or attenuation of vestibular responses) can be achieved through both increase or decrease of otolith afferentation; 3) if joint stimulation of semicircular canals and otolith organs induces asymmetry of neuronal activities of paired brain structures that perceive otolith afferentation, then, irrespective of the mechanism of origin of this asymmetry, it is followed by changes of oppositely directed nystagmus of different sign (increase for one nystagmus and decrease for the other).
