Fig. 3
Time courses of oxygen uptake (VO2, a), carbon dioxide production (VCO2, b), and pulmonary ventilation (V E, c) during rest, exercise, and recovery in all protocol sessions. Horizontal dashed lines identify variables’ resting levels. Values are mean ± SEM percentage changes from the corresponding rest values. *p < 0.05 versus rest; †p < 0.05 versus CER test; # p < 0.05 versus EMI test
