Energy Intake and Energy Expenditure. (A) Energy intake and (C) fecal mass were examined by repeated measures ANOVA for the effect of diet (RS), exercise (EX), time, and their interaction. EXSED rats were excluded from these analyses. (B) Energy intake during the final 4 weekd was examined by repeaed measures ANOVA for the effect of EX/SED (C vs EX vs EX/SED) and time. Sedenary RS-fed rats were excluded from this analysis. (D) Total Energy Expenditure (TEE) for day 0, 1, and 65 of relapse was examined by repeated measured ANOVA for the effect of diet (RS), exercise (EX), time, and their interaction. Values for EX rats includes the energetic cost of the exercise bout, measured in an exercise indirect calorimetry chamber (~2 kcal/bout). Data is shown before and after the adjusting for the variability in lean mass (p < 0.001) by ANCOVA.
