Values are means ± SEs. Statistics were obtained with the use of 2-factor repeated-measures ANOVA with “group” and “day” used to compare differences between groups and test days. No significant group or day effect or interaction was observed for any of the measures; therefore, data are shown as the mean value of both days. COPD, chronic obstructive pulmonary disease; FFM, fat-free mass; PB, protein breakdown; PS, protein synthesis.

Calculated as PS − PB.
