Figure 5.

In the left panels, group mean response of second‐by‐second data for ${\dot{V}}_{\mathrm{E}}$ (A), f_R (C), V _T (E), $\dot{V}{\text{CO}}_2$ (G)_, $\dot{V}{\mathrm{O}}_2$ (I) and P_{ETCO 2} (K) during the entire trapezoidal test. The RPE required by the test is depicted in dashed lines. In the right panels, 60‐sec average values of ${\dot{V}}_{\mathrm{E}}$ (B), f_R (D), V _T (F), $\dot{V}{\text{CO}}_2$ (H), $\dot{V}{\mathrm{O}}_2$ (J) and P_{ETCO 2} (L) for the first (filled circles) and the third (open circles) trapezoidal bouts. When a significant bout × time interaction was found, * depicts significant simple main effect of bout (P < 0.05).
