Number of female (F) and male (M) participants is listed under the group heading. % diff, difference between groups; VO2, oxygen consumption rate; VCO2, carbon dioxide elimination rate; RER, respiratory exchange ratio (= VCO2 / VO2); % diff: difference between groups. P-values are for t-test comparison between groups.
