We gave lady mice medicine called rapamycin either once a week or three times a week while they ran on special wheels for 8 weeks. We wanted to see if the medicine changed how strong or healthy they got from running.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

Even when taking rapamycin, female mice still get stronger and fitter from using a weighted exercise wheel — the drug doesn't stop their workout gains.
In female mice that exercised with weighted wheels for 8 weeks, taking the drug rapamycin — even just once a week — made their blood sugar control worse, but doing it less often caused fewer problems.
Female mice on a weekly rapamycin dose ran more and faster than those on a more frequent dose or no drug, but despite running more, they didn’t lose more fat or get healthier metabolically.
Even when mice are given a drug that blocks a key muscle growth pathway, running with added weight still makes their leg muscles bigger — showing that exercise can build muscle even when that pathway is turned down.
In female mice that exercised with weighted wheels for 8 weeks, giving rapamycin three times a week blocked a key muscle signaling pathway, but giving it just once a week let the pathway bounce back a bit between doses — showing that how often you give the drug really changes how it works in muscles.
