The publication “Intravenous infusion of H2-saline suppresses oxidative stress and elevates antioxidant potential in Thoroughbred horses after racing exercise.” is organized in H2HUBB under the research focus injected hydrogen exercise recovery study 2015. The publication is cited as Yamazaki M, Kusano K, Ishibashi T, Kiuchi M, Koyama K, Scientific reports, 2015. This animal study examined Intravenous infusion of H2-saline suppresses oxidative stress and elevates antioxidant potential in Thoroughbred horses after racing exercise. The abstract describes Animal model; sample size 6; hydrogen delivered as injected or infused hydrogen. The abstract reports: Upon intensive, exhaustive exercise, exercise-induced reactive oxygen species may exceed the antioxidant defence threshold, consequently resulting in muscular damage or late-onset chronic inflammation. This is an automated editorial draft based on the abstract and requires source review before publication.
Injected hydrogen exercise recovery study 2015 overview
We here investigated 13 Thoroughbred horses administered intravenous 2-L saline with or without 0.6-ppm H2 (placebo, N = 6; H2, N = 7) before… Animal research can identify biological effects and support future investigation, but it cannot by itself establish safety or effectiveness in humans.
Study design and hydrogen intervention
Publication type: Animal study. Evidence type: Preclinical animal evidence. Research model or population: Animal model. Sample size: 6. Blinding: Unknown. Control status: Unknown.
Delivery method: Injected or infused hydrogen.
Reported findings and scientific interpretation
For this injected hydrogen exercise recovery study 2015, the study record reports the following: The abstract reports: Upon intensive, exhaustive exercise, exercise-induced reactive oxygen species may exceed the antioxidant defence threshold, consequently resulting in muscular damage or late-onset chronic inflammation.
These findings should be interpreted as one piece of evidence rather than as a stand-alone medical conclusion. Results can be influenced by the research model, study design, treatment protocol, sample size, outcome selection, statistical methods, and whether the findings have been independently reproduced.
How this research record was prepared
H2HUBB organizes bibliographic details, study design information, intervention data, outcomes, limitations, and safety notes from the available scientific source. Automated classification supports database organization, but it does not replace critical reading of the complete paper. Source identifiers, evidence labels, and delivery-method fields are retained so readers can verify the record and compare it with related publications. A missing field means the information was unavailable or not reported in the structured source; it should not be treated as a negative finding.
Limitations, safety, and original source
Limitations: Preclinical animal findings may not translate directly to human outcomes.
Safety: The abstract did not provide detailed safety or adverse-event information.
