Low density, normal density muscle and subfacial fat in skeletal muscle after 28 days bed rest and 14 days active recovery. a) Low density muscle, b) Normal density muscle, c) Subfacial fat, d) Leg lean mass. Values are mean ± SEM. Participants were randomized into amino acid supplement (EAA) group or resistance training with amino acid supplement (RT) group. Open bars: baseline values; grey bars: values after 28 days of BR; filled bars: values after 14 days of active recovery. Repeated measures analyses using General Linear Models (GLM) were carried out to assess the interaction between time [baseline (or pre-bed rest), end of bedrest, and recovery] and group [amino acids vs amino acids plus exercise] on each of the dependent variable studied. *p < 0.001 for time effect, ** p < 0.001 for time-by-group interaction.
