Phosphorylation status of downstream components of mTOR signaling pathway in the EAA + CHO and fasting control group 1 h before exercise (1 h Pre-Ex), immediately before beginning exercise (Pre-Ex), immediately following exercise (Post-Ex), 1 h postexercise (1 h Post-Ex), and 2 h postexercise (2 h Post-Ex). mTOR phosphorylation at Ser2448 (A), 4E-binding protein 1 (4E-BP1) phosphorylation at Thr37/46 (B), S6 kinase 1 (S6K1) phosphorylation at Thr389 (C), and eukaryotic elongation factor 2 (eEF2) phosphorylation at Thr56 (D) are shown. The time course phosphorylation data for the fasting group have been previously published (9). Values are means ± SE. *P < 0.05 vs. 1 h Pre-Ex. #P < 0.05 vs. fasting at respective time point.
