Some editorial classification fields are still pending. The source-reported outcomes and result are shown below; Hydrogenology does not infer a positive or negative signal from prose automatically.
Methods
Human participants studied for exercise and recovery; age 29 years. See eligibility criteria in the linked full text.
Human study; the article does not state one consolidated sample total, so no total is inferred.
24 hours
Full text reports H₂ dissolved in drinking water. Detected intervention quantities or schedules: 24 hours, 4 hours, 60 min, 8 ppm.
H₂ dissolved in drinking water — H₂ only unless the full text explicitly reports oxygen co-delivery.
H₂-related quantities reported in the intervention passages: 24 hours, 4 hours, 60 min, 8 ppm. Values are not combined across different experimental arms.
Control or comparison condition reported in the full article; see the linked methods for arm-specific details.
