Statins and running: new study to reveal hidden effects on endurance athletes
NCT ID NCT07401017
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how the cholesterol-lowering drug rosuvastatin affects fitness and muscle symptoms in people who run long distances at least three times a week. Researchers will compare runners taking rosuvastatin to those not taking it over three months, measuring changes in oxygen use and muscle discomfort. The goal is to understand if this statin interferes with endurance training or increases muscle problems.
