Methods at a glance

Population or model

Human participants studied for exercise and recovery. See eligibility criteria in the linked full text.

Sample

Human study; group or assay counts reported in the full text include n=9.

Duration

1 min

Intervention

Full text reports H₂ dissolved in drinking water. Detected intervention quantities or schedules: 1 min, 2 min, 3 min, 1600 ppb.

Hydrogen form

H₂ dissolved in drinking water — H₂ only unless the full text explicitly reports oxygen co-delivery.

H₂ specification

H₂-related quantities reported in the intervention passages: 1 min, 2 min, 3 min, 1600 ppb. Values are not combined across different experimental arms.

H₂ flow

Not applicable — no inhaled H₂ intervention was identified in the full article.

O₂ delivered with H₂

No inhaled O₂ co-delivery was identified for this non-inhalation intervention.

Comparator

Placebo or matched control reported in the full article.

Reported, not endorsed

Outcomes and reported result

Outcomes measured

clinical symptoms or functional scores, oxidative-stress and antioxidant markers, apoptosis or cell injury, respiratory measures

Reported result

Article-reported result excerpt (24 words maximum): “Two-way mixed design ANOVA models showed a trend towards a significant interaction in the maximum power of the 30 s rowing test (F =…” This excerpt is not a complete result summary; consult the linked full text for all positive and null findings.

Results-extraction completeness

The complete machine-readable article was checked for source identity, methods, intervention quantities, results, tables, funding and conflict declarations. This public record is based on the full article.

A reported association, difference or mechanism is not automatically a clinical benefit. Null findings, outcome type, study design and precision all matter.

Interpretation limits

Cautions and applicability

Design and reporting cautions

Human evidence; design, sample size and comparator limit interpretation. Funding or grant information is reported in the full article. The article declares no conflicts of interest.

Applies directly to

Applies only to the population and protocol reported in this exercise and recovery article.

Preliminary appraisal framework

Not reported in this record.

Preliminary risk-of-bias status

Not reported in this record.

Appraisal rationale

Not reported in this record.

No single-study GRADE certainty rating is assigned. Certainty is assessed by important outcome across a complete eligible evidence set, not by attaching a final grade to one source.
