Response to exercise of (A) energy expenditure along with the proportions derived from carbohydrate and lipid oxidation, (B) respiratory exchange ratio [RER = VCO₂/VO₂], (C) lipid oxidation, and (D) carbohydrate oxidation. Data are median with interquartile range. Measurements were conducted at 8, 15, 30, 60, 90, and 120 min of exercise. n = 17, except in time points 90 min [one missing value] and 120 min [two missing values]. The effect of exercise was tested with the Friedman test for repeated measurements; therefore, only the 15 participants with data in all time points were included in the analyses. *P < 0.05 vs. time point 8 min for the Sign post-hoc test with Bonferroni adjustment.
