NettetBoth strength training and eating a meal rich in amino acids result in an increase in protein synthesis. The increase in protein synthesis in both cases is dependent on a protein kinase called the mammalian target of rapamycin (mTOR). Strength training and amino acid ingestion (eating) activate mTOR in different ways. NettetAbsence of amino acids in the cytosol inhibits mTOR signaling and initiates autophagy to increase amino acid levels through protein degradation in the lysosome. 34 mTORC1 directly phosphorylates unc-51-like autophagy-activating kinase1 (ULK1) and ATG13, two key early effectors in the initiation of autophagy, inhibiting the induction of autophagy …
