Mean time course of $\dot{V}{O}_2$ during the Tlim _supra test in the decrease and no decrease subjects. Time course of oxygen uptake during the Tlim_supra test at each 5% interval-duration in the subjects who present a ≤ 5% (white labels) and > (black labels) $\dot{V}{O}_2$ decrease Values are mean ± SD; * : significant decrease relative to $\dot{V}{O}_{2\mathit{peak}}$, P < 0.05.
