The Claim
Acute resistance exercise activates the ERK and mTOR signaling pathways to a similar extent both before and after 8 weeks of training, indicating that acute anabolic signaling remains unchanged following chronic adaptation.
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.
Even after working out with weights for 8 weeks, your muscles still respond to a single workout the same way as they did at the start—your body doesn’t get better at signaling muscle growth after training for a while.
See the scientific wording
Acute resistance exercise activates the ERK and mTOR signaling pathways similarly before and after 8 weeks of training, indicating that acute anabolic signaling does not change with chronic adaptation.
What the research says
1 studyStudy: Ribosome biogenesis adaptation in resistance training-induced human skeletal muscle hypertrophy.
The study found that after 8 weeks of weight training, a single workout still turned on the same muscle-building signals as it did before training — meaning your muscles don’t get used to these signals over time.
