The Claim
In older adults undergoing 4 weeks of resistance training, individuals exhibiting extreme muscle fiber hypertrophy (+83%) demonstrate a 40% increase in ribosomal RNA content, whereas nonresponders show no significant increase, indicating that ribosome biogenesis is associated with the magnitude of muscle growth.
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.
When older people do strength training for four weeks, those who get much bigger muscles also see a big jump in the cellular machinery that helps build muscle, while people who don’t gain muscle don’t see this change—so it seems like making more of this machinery is tied to getting stronger and bigger.
See the scientific wording
In older adults undergoing 4 weeks of resistance training, those with extreme muscle fiber hypertrophy (+83%) show a 40% increase in ribosomal RNA content, while nonresponders show no increase, suggesting ribosome biogenesis is associated with the magnitude of muscle growth.
What the research says
1 studyIn older adults who did weight training for 4 weeks, those who got much stronger and bigger muscles also made more ribosomes — the cell’s protein factories — while those who didn’t grow didn’t make more ribosomes. This suggests ribosomes help muscles grow bigger.
