Figure 1

The top panel shows the overall RPE vs. power output. At exhaustion from exercise in hypoxia, the subjects were switched to room air and strongly encouraged to continue pedalling until reaching secondary exhaustion. The arrows indicate the measurements after the switch; for reasons of legibility, the arrows are not shown on the other graphs. The middle panel shows the RPE breathing vs. power output. The bottom panel shows the RPE legs vs. power output. Error bars were omitted for clarity. The coloured symbols and lines represent the same conditions for all figures.
