The Claim

In humans, the extent of ribosome biogenesis during resistance exercise training is positively correlated with the magnitude of skeletal muscle hypertrophy, with high responders exhibiting significantly greater increases in ribosomal content compared to low responders; changes in ribosome content are associated with muscle fiber cross-sectional area, and mechanistic evidence from rodent and in vitro models indicates that ribosome biogenesis plays a critical role in myofiber growth.

In plain English

People who build more muscle from weight training tend to make more ribosomes—the tiny machines in cells that build proteins—compared to those who don’t gain as much muscle. One study found big gains in these protein-makers in strong responders, and lab studies back up that this process helps muscle grow.

See the scientific wording

The degree of ribosome biogenesis during resistance exercise training is associated with the magnitude of skeletal muscle hypertrophy in humans, with high responders showing significantly greater increases in ribosomal content compared to low responders. For example, one study found a 32% increase in ribosome content in high responders versus an 8% non-significant change in low responders after 12 weeks of training, and ribosome content changes correlated with muscle fiber cross-sectional area (r = 0.72). Mechanistic evidence from rodent and in vitro models supports that ribosome biogenesis is critical for myofiber growth.

    The study looks at people who gain more or less muscle from the same workout routine and finds that those who gain more muscle also show bigger increases in the cell machinery needed to build muscle, like ribosomes.
