Breathe easy, climb higher: study tests simple tricks for altitude endurance

NCT ID NCT07216755

First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study tests whether strengthening your breathing muscles with a handheld device and taking nitrate supplements (like those in beetroot juice) can improve exercise performance in simulated high altitude. Eighty healthy adults will train for 4-6 weeks and then do a cycling test in a low-oxygen chamber. The goal is to see if these simple, non-drug strategies can help the body use oxygen more efficiently.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

nitrate supplement

What this could lead to

If it works, this could point toward simple, non-drug ways to help people exercise better in low-oxygen conditions, like at high altitudes or with certain lung conditions.

What could go wrong

This is a small, early study in healthy adults, not patients. The simulated altitude may not reflect real-world conditions, and results may not apply to people with medical issues.
