Exercise Physiology | AMP, AMPK, & Energetic Stress

The video explains the role of AMP as a biosignal for energetic stress in skeletal muscles during exercise. It discusses ATP synthase's function in muscle contraction and the cycle of ATP hydrolysis and regeneration. The accumulation of ADP and its conversion by myokinase to AMP and ATP is highlighted. AMP activates AMPK, which promotes catabolic processes and inhibits protein synthesis by affecting mTOR. The video concludes with the interplay between AMPK and mTOR during exercise, emphasizing the need to balance their activities for muscle hypertrophy.
