Hydrogen Water Boosts Athletic Power But Not Endurance, Study Shows

TL;DR

Scientists looked at whether drinking or taking molecular hydrogen could help people exercise better, and found it only really helps with explosive leg power (like jumping) and makes exercise feel less exhausting—but it doesn't actually boost endurance, strength, or overall aerobic fitness.

Key Finding

Molecular hydrogen supplementation showed a small but statistically significant improvement in lower limb explosive power and reduced perceived fatigue during exercise, but did not enhance aerobic endurance, anaerobic endurance, or muscular strength in healthy adults.

Summary

Researchers analyzed 27 studies involving 597 healthy adults to see whether molecular hydrogen (H₂) supplementation could improve physical performance. They found that H₂ had a small positive effect on lower limb explosive power (like jumping ability) and reduced how hard exercise felt, but it did not meaningfully improve aerobic endurance, anaerobic endurance (short bursts of intense effort), or muscular strength.

Practical Takeaway

If you're interested in hydrogen water for athletic performance, early evidence suggests it may modestly help with explosive movements like jumping and reduce how tired you feel during exercise. However, the benefits appear limited to these specific areas—it does not appear to boost overall endurance or strength. The studies analyzed were relatively small and varied in design, so more rigorous research is needed before drawing firm conclusions.

Abstract (excerpt)

BackgroundPhysical exertion during exercise often leads to increased oxidative stress and inflammatory responses, significantly affecting physical performance. Current strategies to mitigate these effects are limited by their effectiveness and potential side effects. Molecular hydrogen (H₂) has…
