The data are presented as the means ± standard deviations. P, power; $\stackrel{.}{V}$O₂, oxygen uptake; $\stackrel{.}{Q}$, cardiac output; SV, stroke volume; HR, heart rate; avDO₂, arteriovenous oxygen difference; CaO₂, arterial oxygen content; SpO₂, peripheral oxygen saturation; [Hb]_ven, venous hemoglobin concentration. Significant differences compared to the resting values are indicated as follows: ***significant compared to resting values (p < 0.001), ^#significant compared to 60% P_max (p < 0.05).
