The Claim

Resistance exercise increases AMPK activity for up to 1 hour post-exercise, yet muscle protein synthesis still rises during this time, suggesting that anabolic signals (Akt, mTOR, S6K1) can override AMPK-mediated inhibition during recovery.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

Even though your muscles get a signal to slow down energy use after lifting weights, they still keep building protein—like your body’s repair crew is ignoring the ‘slow down’ sign because the ‘build up’ signal is stronger.

    After lifting weights, a cellular brake (AMPK) is on, but by 1 hour later, even though the brake is still partly on, the gas pedal (Akt/mTOR/S6K1) gets pushed harder and makes muscles grow anyway.
