The Claim
A single bout of resistance exercise in healthy young adults is associated with a 75% increase in AMPKα2 activity and a 36% reduction in 4E-BP1 phosphorylation at Thr37/46 immediately after exercise, which coincides with a 32% decrease in muscle protein synthesis, suggesting that AMPK activation may contribute to the transient suppression of anabolic signaling during high-energy-demand conditions.
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.
After a single workout with weights, your muscles temporarily slow down their protein-building process, and this might be because a specific energy-sensing molecule (AMPK) gets more active and tells the building machinery to take a break.

What the research says
1 studyAfter a workout, the body temporarily slows down muscle building to save energy, and this study shows that a key energy sensor (AMPK) turns on and turns off a protein (4E-BP1) that helps build muscle — exactly what the claim says.
