H2HUBB TAKEAWAY
In rats, specifically, HRW improved repeated sprint ability by maintaining higher av- erage power output and effectively reducing the magnitude of power decline across sprints. No significant ef- fect was observed on peak power, indicating that HRW supports sustained rather than maximal single-sprint power. These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.
What the Findings Mean
H2HUBB reviewed how hydrogen-rich water affected the outcomes measured in rats. Specifically, HRW improved repeated sprint ability by maintaining higher av- erage power output and effectively reducing the magnitude of power decline across sprints.
What the Researchers Studied
The researchers studied rats. The study used a preclinical animal experiment.
What Effects Did Molecular Hydrogen Have?
©Journal of Sports Science and Medicine (2026) 25, 744-752 http://www.jssm.org DOI: https://doi.org/10.52082/jssm.2026.744 Received: 17 April 2026 / Accepted: 13 July 2026 / Published (online): 01 September 2026 ` Effects of Hydrogen-Rich Water Supplementation on Exercise Perf ormance, Autonomic Nervous System Recove ry, and Blood Lactate Concentrat ion During Repeated Sprint Exercise in Male University Athletes Zhihao Chen, Meilan Chi, Ruizhi Liu, Lianzhen Ma And Yupeng Shen Institutional Affiliations: School of Physical Education and Sports Science, South China Normal University, Guangzhou, China Abstract Hydrogen-rich water (HRW) supplementation has been proposed to exert anti-fatigue effects during exercise. However, its imp act on exercise performance and a utonomic nervous system (ANS) function during repeated sprinting remains unclear. Fourth, dissolved hydrogen concen- tration in the water was not v erified immediately prior to each ingestion session; any concentration decay between preparation and consumption could reduce the actual H₂ dose received. Specifically, HRW improved repeated sprint ability by maintaining higher av- erage power output and effectively reducing the magnitude of power decline across sprints. The authors concluded that this dissociation – a clear benefit for aver- age power but not peak power – suggests that HRW primar- ily supports the maintenance of sustained power output across repeated efforts rather than maximal single-sprint explosiveness, possibly reflecting its proposed role in at- tenuating cumulative oxidative and metabolic fatigue ra- ther than enhancing peak neuromuscular output.
Why These Findings Matter
These preclinical findings add evidence supporting molecular hydrogen's therapeutic potential within the outcomes and biological pathways measured in this model.
How Strong Is This Evidence?
This is preclinical animal evidence from a preclinical animal experiment. It is most informative for the disease model, mechanisms, biomarkers, and outcomes directly measured in the study.
