The Claim

Resistance training induces skeletal muscle hypertrophy by stimulating ribosome biogenesis, thereby increasing the muscle cell's translational capacity to synthesize new contractile proteins over time.

What the research says

Roughly balanced

Support and challenge are close. The picture may shift as more studies come in.

Challenges

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

When you lift weights, your muscles grow bigger because your body makes more tiny protein-making machines inside muscle cells, which helps build more of the proteins that make muscles strong and bulky.

See the scientific wording

Resistance training increases skeletal muscle hypertrophy by enhancing ribosome biogenesis, which expands the muscle’s translational capacity to synthesize new contractile proteins over time.

What the research says

1 study

  1. Study: Mechanisms of mechanical overload-induced skeletal muscle hypertrophy: current understanding and future directions.

    This study says that lifting weights makes muscles grow bigger partly by helping muscle cells make more ribosomes — tiny machines that build muscle proteins — which is exactly what the claim says.
