FIGURE 4.

Skeletal muscle Akt, mTOR, and 4E-BP1 phosphorylation (relative to total protein expression) in the basal state and at 1.5 and 3.0 h of EAA+sucrose consumption in healthy older adults after a control (▪) or aerobic exercise (□) treatment. n = 6 for each treatment by using a randomized crossover design. Representative basal images are included for comparison. Paired t tests were used to compare the basal state with EAA+sucrose at 1.5 and 3.0 h within treatments (control and exercise) and delta scores between treatments.^*Significantly different from basal. P < 0.05. Akt, protein kinase B; AU, arbitrary units; EAA, essential amino acids; mTor, mammalian target of rapamycin; 4E-BP1, 4E-binding protein 1.
