Comparison of the Influence of Hyperoxia on Short-term Performance at Low and Higher Altitudes
Vol.4,No.1(2010)
The article compares the influence of inhaling concentrated oxygen on short-term repeated performance at low altitude and at high altitudes above sea level (1 835 m a.s.l.). The source of concentrated oxygen used was Oxyfit. The subjects (n=10) completed a total of four tests comprised of two Wingate tests at 10-minute intervals. 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 were given a placebo. The study showed a significantly (p < 0.05) higher performance level of the repeated Wingate tests after inhaling concentrated oxygen in comparison with the placebo group at both low and high altitudes. Inhalation of concentrated oxygen affects performance to a greater extent at the high altitude compared to that of low altitude.
