Respiratory exchange ratio and blood metabolite levels in the treadmill running test. Running proportions (A), time-course changes in the respiratory exchange ratio (RER) (B), and average RER (C) during 60 min of treadmill running. Time-course changes in O2 consumption (VO2)/bodyweight (D), and average VO2/bodyweight (E) during 60 min of treadmill running. Average RER (C) during 60 min of treadmill running. Time-course changes in CO2 production (VCO2)/bodyweight (F), and average VCO2/bodyweight (G) during 60 min of treadmill running. Blood glucose concentrations before (H) and after (I) exercise. Blood lactate concentrations before (J) and after (K) exercise. Data are expressed as the mean ± SEM (n = 5–11). The running proportion curves in the treadmill running test were compared using the log-rank (Mantel–Cox) test. For the time course changes in RER, two-way ANOVA (time × group) followed by the Tukey–Kramer multiple comparison test was performed. To determine the interactions and main effects of training and ORX, two-way ANOVA followed by the Tukey–Kramer multiple comparison test was performed. #p < 0.05: ORX-sedentary group vs. sham-training group. ‡p < 0.05: sham-sedentary group vs. ORX-training group. ¶¶p < 0.01: ORX-sedentary group vs. ORX-training group. **p < 0.01, (*)p ≤ 0.10: effect of training. §§p < 0.01: significantly different from other groups
