H2HUBB TAKEAWAY
In In a randomized, double-blind study design, all players ingested 500 mL of HRW or placebo (PLA) supplement 30 min before the start of the tests, 500 mL of HRW can significantly improve HRpeak, time to exhaustion, RPE, with no significant effect on MAS, jumping performance in amateur endurance athletes. These findings add human evidence supporting molecular hydrogen's therapeutic potential across the specific human outcomes evaluated in this study.
What the Findings Mean
H2HUBB reviewed how hydrogen-rich water affected the outcomes measured in In a randomized, double-blind study design, all players ingested 500 mL of HRW or placebo (PLA) supplement 30 min before the start of the tests. 500 mL of HRW can significantly improve HRpeak, time to exhaustion, RPE, with no significant effect on MAS, jumping performance in amateur endurance athletes.
What the Researchers Studied
The researchers studied In a randomized, double-blind study design, all players ingested 500 mL of HRW or placebo (PLA) supplement 30 min before the start of the tests. The study used a randomized, double-blind, placebo-controlled human clinical trial. The comparison condition was placebo.
What Effects Did Molecular Hydrogen Have?
500 mL hydrogen-rich water per reported dose; dissolved H₂ concentration was not reported in the available source text, so H2HUBB did not estimate milligrams of H₂. 500 mL of HRW can significantly improve HRpeak, time to exhaustion, RPE, with no significant effect on MAS, jumping performance in amateur endurance athletes.
Why These Findings Matter
These findings add human evidence supporting molecular hydrogen's therapeutic potential across the specific human outcomes evaluated in this study and contribute to the growing body of molecular-hydrogen research.
How Strong Is This Evidence?
This is human clinical evidence from a randomized, double-blind, placebo-controlled human clinical trial. H2HUBB interprets the findings in the context of the study design, sample, comparator, and measured outcomes rather than using one publication as a verdict on hydrogen therapy.
Technical Study Details
H2HUBB classifies this publication as human clinical study with human clinical evidence. The research population or model was In a randomized, double-blind study design, all players ingested 500 mL of HRW or placebo (PLA) supplement 30 min before the start of the tests. The reported sample size was 2. The study used a randomized, double-blind, placebo-controlled human clinical trial. The hydrogen delivery method was hydrogen-rich water. H2HUBB translates the reported hydrogen dose as 500 mL hydrogen-rich water per reported dose; dissolved H₂ concentration was not reported in the available source text, so H2HUBB did not estimate milligrams of H₂.
Limitations and Safety
No separate limitations or safety findings were identified in the source text available to H2HUBB.
