Could a diabetes pill boost high-altitude exercise performance?
NCT ID NCT06164665
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at whether pioglitazone, a drug used for diabetes, can help the body use sugar from food during exercise at high altitude. Nine healthy men took either the drug or a placebo for five days, then exercised on a treadmill in a chamber simulating high altitude. Researchers measured how much sugar the body burned and how it affected inflammation and iron levels.

- Active substance
- Pioglitazone (15 mg oral daily for 5 days)
- What this could lead to
- If successful, this could point toward ways to improve energy use and performance during high-altitude activities.
- What could go wrong
- This is a very small, early-phase study with only 9 healthy men. Results may not apply to women, less fit people, or real-world high-altitude conditions.
