H2HUBB TAKEAWAY
However, in the secondary analyses, the one-way repeated measures ANOVA model showed that within the HRW group, the maximum power (F = 9.396, p = 0.015) and average power (F = 5.544, p = 0.046) were significantly improved after the intervention as compared to baseline. No significant changes in these two outcomes within the PW group were observed (F 0.768). This source-grounded publication contributes evidence relevant to molecular hydrogen and is retained in a transparent general research category when a more specific study design is not supported by the indexed record.
What the Findings Mean
H2HUBB reviewed how hydrogen-rich water was evaluated in this publication and summarizes the source-grounded findings below. However, in the secondary analyses, the one-way repeated measures ANOVA model showed that within the HRW group, the maximum power (F = 9.396, p = 0.015) and average power (F = 5.544, p = 0.046) were significantly improved after the intervention as compared to baseline. No significant changes in these two outcomes within the PW group were observed (F 0.768).
What the Researchers Studied
The comparison condition was placebo.
What Effects Did Molecular Hydrogen Have?
Source-reported hydrogen concentration: 1600 ppb H₂ (≈1.6 mg/L); Source-reported hydrogen exposure: 1000 mL hydrogen-rich water/day; approximately 1.60 mg H₂ across the reported daily volume; reported treatment duration: 7 days. However, in the secondary analyses, the one-way repeated measures ANOVA model showed that within the HRW group, the maximum power (F = 9.396, p = 0.015) and average power (F = 5.544, p = 0.046) were significantly improved after the intervention as compared to baseline. No significant changes in these two outcomes within the PW group were observed (F 0.768). The authors concluded that drinking HRW in the short term can effectively improve the power performance of dragon boat athletes and is conducive to the recovery of the heart rate after exercise, indicating that HRW may be a suitable means of hydration for athletes.
Why These Findings Matter
These findings add evidence supporting molecular hydrogen's therapeutic potential within the biological process and outcomes directly measured in this publication and contribute to the growing body of molecular-hydrogen research.
How Strong Is This Evidence?
H2HUBB classifies this publication as other research and interprets only the outcomes directly supported by the source record.
Technical Study Details
H2HUBB classifies this publication as other research with other supported evidence. The reported sample size was 6. The hydrogen delivery method was hydrogen-rich water. The source-reported hydrogen concentration was 1600 ppb H₂ (≈1.6 mg/L). The source-reported hydrogen exposure was 1000 mL hydrogen-rich water/day; approximately 1.60 mg H₂ across the reported daily volume. The reported treatment duration was 7 days.
Limitations and Safety
Reported limitations: One of the most significant limitations is the small sample size (n = 9 in each group) and short duration of the test (only 30 s).
Original Study and H2HUBB Research Context
H2HUBB presents this source-grounded research record as one contribution to the broader molecular-hydrogen evidence base.
