TL;DR
Drinking hydrogen-rich water (HRW) seems to help people maintain a lower heart rate during moderate exercise without affecting their maximum exercise abilities.
Key Finding
Hydrogen-rich water supplementation reduced average heart rate and breathing rate during moderate-intensity exercise, but did not improve maximum exercise performance or oxygen utilization.
Summary
This study tested whether hydrogen-rich water (water infused with extra hydrogen molecules) could improve exercise performance in 19 healthy adults. Participants drank either hydrogen-rich water or a placebo drink on two separate occasions before exercising on a treadmill. While hydrogen-rich water didn't change maximum performance, it did lower heart rate and breathing rate during moderate-intensity exercise without affecting oxygen use.
Practical Takeaway
This small pilot study suggests hydrogen-rich water may help the body work more efficiently during moderate exercise by lowering heart rate, though the practical benefit remains unclear. The study was brief and involved only 19 people, so much larger and longer studies are needed before drawing firm conclusions about whether this effect matters for real-world fitness or health.
Abstract (excerpt)
Background: Clinical studies have reported hydrogen-rich water (HRW) to have therapeutic and ergogenic effects. The aim of this study was to determine the effect of acute supplementation with HRW on exercise performance as measured by VO2, respiratory exchange ratio (RER), heart rate (HR)…
