BMR, basal metabolic rate; V̇_{O2max}, maximal oxygen consumption in exercise; V̇_{O2sum}, maximal oxygen consumption in thermogenesis; f, breathing frequency; V_{T}, tidal volume; V̇_{min}, minute volume; E_{O2}, oxygen extraction.
Age, mass and metabolism were log_{e}-transformed prior to analysis. ANCOVA with mass and age as covariates was used to test for sex differences, and multiple regression was used to examine the effects of age and mass. Separate partial correlation coefficients (r) and P values are given for males (M) and females (F) for variables where the sexes differed significantly. P values with an asterisk (*) remained significant after sequential Bonferroni correction (adjustedα =0.008; Rice, 1989).
