Changes in Net whole body protein synthesis of the healthy control group (upper panel, n=8) during 20 minutes of low and high intensity exercise both followed by 1 hour of recovery, and the COPD group (lower panel, n=8) during 20 minutes of exercise and 1 hour of recovery, during intake of a casein protein meal (circles) vs. a whey protein meal (squares) provided every 20 min until the end of the test day. Mean values ± 1 SE are shown. Repeated measures mixed model ANOVA: there was a significant protein effect during exercise and recovery in the COPD and control group (p<0.01). There was a significant time effect during both exercise and recovery in the COPD group (p<0.001) but during heavy exercise and recovery in the control group (p<0.05). There was no significant protein by time interaction during exercise and recovery in the COPD and control group. The absolute response in Net PS during intake of the whey protein meal was different from 0 (NetPS=0) during exercise and recovery in the COPD group (P<0.05) and during the whole study period in the healthy control group (P<0.01) with the exception of recovery from heavy exercise.
