Porovnání vlivu hyperoxie na krátkodobý anaerobní výkon v nížině a vyšší nadmořské výšce
Comparison of the Influence of Hyperoxia on Shortterm Performance at Low and Higher Altitudes

Summary/Abstract: The article compares the influence of inhaling concentrated oxygen on short-term repeated performance in lowlands and at high altitudes above sea level (1 835 m a.s.l.). The source of concentrated oxygen was Oxyfit. The subjects (n=10) completed a total of four tests comprised of two Wingate tests at a 10 minute interval. Two tests were carried out at a low altitude and two at a higher altitude above sea level. During the recovery period between tests the monitored subjects inhaled Oxyfit or a placebo (at both the low and high altitudes). The study showed significantly (p < 0.05) higher performance of the repeated Wingate test after inhaling concentrated oxygen in comparison with the placebo at both low and higher altitudes. Inhalation of concentrated oxygen affects performance to a greater extent at the higher altitude compared to that of the low altitude.
