Arterial oxygen saturation, blood lactate concentration, blood gases, and acid-base balance during submaximal at different simulated altitudes before and after intermittent hypoxic exposure.

IHE = intermittent hypoxic exposure,P40/P60 = work load corresponding to 40/60% of peak oxygen uptake in normoxia,SaO2 = arterial oxygen saturation, LA = blood lactate concentration (LA),PaO2 = arterial pressure of oxygen, PaCO2 = arterial pressure of carbon dioxide, HCO3 = bicarbonate concentration.Values are means±SD.Altitude effects = general effect (ANOVA) of the simulated altitude.IHE effect = general effect (ANOVA) of IHE application (before vs. after) independent of simulated altitude.There were no significant interactions (ANOVA) between simulated altitude and IHE.ns p≥0.05,*p**p§p§§p
