The Claim

In sedentary adults aged 65–85 years, once-weekly sirolimus (rapamycin) 6 mg administered alongside a 13-week home-based resistance and endurance exercise program may modestly attenuate improvements in lower-body functional performance, as measured by the 30-second chair-stand test, compared to placebo, with sensitivity analyses showing statistically significant differences favoring placebo despite a non-significant primary analysis.

What the research says

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Cause and effect
1 study reviewed
In plain English

In older adults who don't move much, taking a weekly rapamycin pill might slightly weaken the benefits of a 13-week home exercise program on leg strength and mobility, according to some detailed number crunching—even though the main results weren't clear-cut.

What the research says

1 study
  1. Study: Exercise and Weekly Sirolimus (Rapamycin) in Older Adults: RAPA‐EX‐01 Randomised, Double‐Blind, Placebo‐Controlled Trial

    The study found that older adults taking sirolimus once a week didn't improve as much on a chair-stand test as those taking a placebo, especially when looking at more detailed analyses. This supports the idea that the drug might slightly reduce exercise benefits.
