Values are means ± SE, adjusted for room and sex. EE, energy expenditure; FFM, fat-free mass; RQ, respiratory quotient; PAL, physical activity level.

PAL was calculated as 24-h EE/RMR, where RMR is resting metabolic rate.

*

P < 0.01, exercise condition (EX) vs. control condition (CON). Different superscript letters (a, b) indicate significant differences between groups determined using a one-factor ANOVA.
