Abstract
Two investigations were designed that (a) evaluated the effect of the respiratory alkalosis that accompanies breathing an hypoxic (H) gas mixture and (b) examined the influence of the duration of breathing this H mixture on the subsequent performance of 45 s supramaximal dynamic exercise. In experiment 1, 12 men performed a 45-s Wingate Test (WT) on three occasions breathing a normoxic (N; 20.9% O2), H (11.3% O2), or normocapnic hypoxic (H+CO2; 11.5% O2, 2.25% CO2) gas mixture for 20 min prior to performing the WT. For experiment 2, nine men performed a 20-min normoxic (N2O) and three hypoxic WT trials which consisted of breathing an 11% O2 balance N2 gas mixture for 10 min (H10), 20 min (H2O) or 30 min (H3O) prior to the WT.
