Army study: fiber fuel may improve 5K run times
NCT ID NCT06054607
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether short-chain fatty acids (SCFAs), which are produced when gut bacteria break down certain fibers, can improve aerobic endurance. 21 healthy, active adults ate a low-fiber diet with either a SCFA-boosting starch or a regular starch for one week, then did a 5km treadmill run. Researchers measured run time, muscle fuel, and metabolism to understand how SCFAs affect performance.
