Exercise Physiology | mTORC1 and Muscle Protein Synthesis

The video explains the role of mTORC1 in muscle protein synthesis and hypertrophy. It details how amino acids, particularly leucine and arginine, activate mTORC1, which is crucial for muscle growth. The video also covers the mechanisms of mTORC1 activation, including the involvement of Gator proteins and Rag GTPases. Additionally, it discusses the functions of mTORC1 in stimulating protein synthesis and inhibiting autophagy, highlighting the importance of amino acids and other factors like glucose and growth factors in this process.
