Objective of the study was to study the effect of the severity of normobaric hypoxia on the indicators of blood saturation and the cardiovascular system during mental work.
Methods and structure of the study. The experiment involved highly skilled swimmers who performed test tasks for mental performance. After completing the test tasks, a hypoxic test was carried out using a hypoxicator. Blood saturation (SO2) and CVS parameters were measured, which were used to assess the severity of hypoxic exposure, as well as to study the dependence of changes caused by NH and changes in mental performance.
Research results and conclusions. It has been shown that exposure to NH (10% O2) is associated with changes in the functioning of the cardiovascular system, which indicate a pronounced sympathoadrenal reaction aimed at mobilizing the body in response to a new stimulus, and is manifested by an increase in heart rate and an increase in cerebral blood flow. The nature of the urgent adaptive response of the cardiovascular system to a hypoxic stimulus serves as a possible criterion for predicting the degree of positive effect of normobaric hypoxia on the cardiovascular system during mental work.

Keywords: hypoxia, mental performance, blood saturation, oxygen transport system.
