The purpose: to identify variations in the cardiovascular system activity after performing physical exercises in various simulated conditions of hypoxia. Materials and methods: unacclimatized athletes performed graduated physical exercises using a veloergometer under normal conditions and then under artificial hypoxia (884 meters (oxygen content of approximately 19%), 1707 meters (oxygen content of approximately 17,5%), 3085 meters (oxygen content of approximately 15%) created by a hypoxic generator. Heart rate, blood pressure and oxygen blood saturation were recorded prior to the experimental survey. The same parameters were recorded immediately after the physical effort test, at the second and fifth minutes of recovery. The test subjects breathed in hypoxic mixture for 5 minutes prior to the exercise during the application of the hypoxic generator. Results: considering the fact that statistically significant variations in blood oxygen saturation have been recorded from a height of 884 meters, it can be noted that the oxygen transport function can not cope with given physical efforts. In our opinion, the limiting factor in this case is the oxygen diffusive ability of the lungs, which is clearly insufficient under given conditions and, as a consequence, there is a significant decrease in saturation with an increase in muscle oxygen demand. With the altitude increase in a stable condition, no significant changes in the oxygen saturation are noted, and after physical intensification it drops dramatically, so five minutes are insufficient to return to the initial values.
