Hydrogen Water Protects Athletes from Exercise-Induced Oxidative Stress

TL;DR

Drinking hydrogen-rich water helped maintain the body's antioxidant levels and may prevent muscle fatigue during consecutive days of intense exercise.

Key Finding

Hydrogen-rich water suppressed the decline in blood antioxidant capacity that occurred over three consecutive days of intense exercise, while placebo water did not provide this protection.

Summary

This study tested whether drinking hydrogen-rich water could help reduce oxidative stress (cellular damage from intense exercise) in eight physically active men who performed strenuous sprint exercises over three consecutive days. While both groups performed equally well, men who drank hydrogen-rich water maintained better antioxidant levels (the body's natural defense against cellular damage) compared to those who drank regular water, suggesting hydrogen water may help protect against exercise-induced stress.

Practical Takeaway

This small human study suggests hydrogen water may help maintain the body's antioxidant defenses during intense training periods, though the practical benefit for exercise recovery remains unclear since actual exercise performance and muscle fatigue symptoms were not different between groups. More research with larger groups and longer follow-up is needed to determine whether this antioxidant protection translates to meaningful improvements in training outcomes or recovery.

Abstract (excerpt)

Repeated sprint exercise can interfere with intramuscular redox balance and cause systemic oxidative stress and muscle damage. There is growing evidence that molecular hydrogen counteracts oxidative and/or inflammatory responses. Therefore, we investigated the effects of molecular hydrogen-rich…
