The Claim

In adult female mice subjected to 8 weeks of progressive weighted wheel running (PoWeR), both intermittent (2 mg/kg once weekly) and frequent (2 mg/kg three times weekly) rapamycin administration do not impair improvements in maximal exercise capacity or absolute grip strength, suggesting that mTOR inhibition with rapamycin does not interfere with key physical performance benefits induced by high-volume voluntary exercise.

Source: Rapamycin does not compromise physical performance or muscle hypertrophy after PoWeR while intermittent rapamycin alleviates glucose disruptions by frequent rapamycin

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.

How it works
1 study reviewed
In plain English

In female mice that exercised a lot for 8 weeks, taking rapamycin — a drug that affects aging — either once a week or three times a week didn’t stop them from getting stronger or improving their stamina.

See the scientific wording

In adult female mice undergoing 8 weeks of progressive weighted wheel running (PoWeR), both intermittent (2mg/kg once weekly) and frequent (2mg/kg three times weekly) rapamycin dosing do not impair improvements in maximal exercise capacity or absolute grip strength, indicating that mTOR inhibition via rapamycin is compatible with key physical performance benefits of high-volume voluntary exercise.

What the research says

1 study
  1. Study: Rapamycin does not compromise physical performance or muscle hypertrophy after PoWeR while intermittent rapamycin alleviates glucose disruptions by frequent rapamycin

    The study found that giving mice rapamycin, even frequently, didn’t stop them from getting stronger or improving their endurance with exercise, which is exactly what the claim says.
