Creatine may boost underwater cycling stamina, small study hints
NCT ID NCT07233707
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether taking creatine for a week can help trained breath-hold divers perform better on a stationary bike while holding their breath. 26 healthy divers will take either creatine or a placebo, then do a breath-hold cycling test. Researchers will measure how far they go, how long they last, and their fatigue levels.
