The Claim
Resistance exercise triggers mechanotransduction pathways in human skeletal muscle, including activation of the FAK-PA-YAP/TAZ axis and Filamin-C/Bag3 complexes, which promote anabolic signaling and may enhance sensitivity to leucine, contributing to muscle hypertrophy.
What the research says
Roughly balanced
Support and challenge are close. The picture may shift as more studies come in.
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 sense the tension and turn on internal signals that help them grow bigger—and they might even become better at using leucine, a protein-building block, to help with that growth.

What the research says
1 studyThis study says lifting weights causes muscles to grow by activating internal body signals — and the claim says one of those signals involves specific proteins that help muscles respond to protein (like leucine). Since the study confirms the general idea that weightlifting triggers these growth signals, it supports the claim.
