The Claim

Myonuclear addition to muscle fibers is associated with extreme hypertrophy in older adults following resistance training, with extreme responders gaining 32% more myonuclei per fiber compared to nonresponders.

Source: Ribosome biogenesis may augment resistance training-induced myofiber hypertrophy and is required for myotube growth in vitro.

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.

In plain English

When older people do strength training and their muscles grow a lot, the muscle cells add more nuclei—and those who grow the most gain about 32% more nuclei than those who don’t grow much.

What the research says

1 study

  1. Study: Ribosome biogenesis may augment resistance training-induced myofiber hypertrophy and is required for myotube growth in vitro.

    The study found that older adults who got much stronger and bigger from weight training also gained many more nuclei in their muscle fibers — exactly what the claim says. The numbers match: extreme responders gained 32% more nuclei, just like the claim stated.
