The Claim
During resistance exercise, muscle protein synthesis is suppressed, but it increases significantly between 1 and 2 hours after exercise, coinciding with elevated phosphorylation of Akt, mTOR, and S6K1, which indicates a rapid shift from catabolic to anabolic signaling during recovery.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When you lift weights, your muscles temporarily stop building protein, but right after you finish, they kick into high gear to repair and grow—this happens because key signaling molecules in your muscles get activated during recovery.

Muscle protein synthesis is suppressed during resistance exercise but increases significantly by 1–2 hours post-exercise, coinciding with elevated phosphorylation of Akt, mTOR, and S6K1, indicating a rapid shift from catabolic to anabolic signaling during recovery.
What the research says
1 studyDuring weightlifting, your muscles temporarily stop building protein, but right after you finish, they start building it faster than before — and this study shows the exact molecular switches (Akt, mTOR, S6K1) that turn on to make that happen.
