Figure 1. Arterial blood parameters.

Figure 1

Arterial O2 content (A), O2 tension (B), haemoglobin concentration (C), CO2 tension (D), O2 saturation (E), pH (F), base excess (G) and lactate concentration (H). Values are plotted for pre-exercise baseline (BL), test gas wash-in (WI), for the duration of the shortest trial in that condition and extrapolated to the group mean exercise time. Data are means ± SEM for 6 participants. *P < 0.05 vs. control at the same time point; †P < 0.05 vs. normoxia at end-exercise.
