Akt, mammalian target of rapamycin (mTOR), S6 kinase (S6K)1, eukaryotic initiation factor 4E-binding protein (4E-BP)1. Data represent phosphorylation fold change of Akt at Ser473 (A), mTOR at Ser2448 (B), S6K1 at Thr389 (C) and 4E-BP1 at Thr37/46 (D) at baseline, 3, 6 and 24 hours after exercise. Representative immunoblot images are shown. Significantly different from *baseline (P < 0.05); #from older subjects (P < 0.05).
