The Claim
Following 12 weeks of resistance training, increases in muscle total RNA (a proxy for ribosome density) were greater in high responders compared to low responders, but this change accounted for only 8% of the variation in muscle growth, indicating that ribosome biogenesis is a weak correlate rather than a strong driver of hypertrophy.
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.
People who gain more muscle from weight training also tend to have more RNA in their muscles, but this only explains a tiny part—about 8%—of why they got bigger. So while RNA levels go up, they’re not really the main reason muscles grow.

What the research says
1 studyAfter 12 weeks of weight training, some people’s muscles grew more than others, and those who grew the most also had more ribosomes—but ribosomes only explained a tiny part of why some people grew bigger muscles. So, ribosomes aren’t the main reason muscles get bigger.
