Hydrogen-Rich Water as a Performance-Enhancing Aid in National-Level Finswimmers: A Randomized, Double-Blind, Placebo-Controlled Crossover Study

BSBarbora SládečkováPalacký University Olomouc JKJakub KrejčíPalacký University Olomouc AMAndrew McKuneUniversity of Canberra

Key Points

To investigate the effects of hydrogen-rich water (HRW) on performance in national-level finswimmers.
Conducted a randomized, double-blind, placebo-controlled crossover study
Administered HRW and placebo to finswimmers
Measured sprint performance and physiological responses including blood lactate and perceived exertion
HRW supplementation led to a 0.6% improvement in middle-distance finswimming performance
Effects on repeated sprint performance were limited
No significant changes in blood lactate, perceived exertion, or oxidative stress were noted

Abstract

Short-term HRW supplementation provides a modest yet meaningful performance improvement of 0.6% in middle-distance (400-m surface) finswimming. However, its effects on repeated sprint performance, blood lactate, perceived exertion, and oxidative stress appear limited.
