Purpose: Molecular hydrogen has been shown to possess antioxidant, anti-inflammatory, ergogenic, and recovery-enhancing effects. This study aimed assess the effect of molecular administration on muscle performance, damage, perception soreness up 24 h recovery after two strenuous training sessions performed same day in elite fin swimmers. Methods: Eight females (mean ± SD; age 21.5 5.0 years, maximal oxygen consumption 45.0 2.5 mL.kg −1 .min ) four males (age 18.9 1.3 52.2 1.7 12 × 50 m sprints morning session a 400 competitive performance afternoon session. Participants consumed hydrogen-rich water (HRW) or placebo 3 days before (1,260 mL/day) 2,520 mL experimental day. Muscle (countermovement jump), damage (creatine kinase), (100 mm visual analogue scale) were measured during at Results: HRW compared reduced blood activity creatine kinase (156 63 vs. 190 64 U.L , p = 0.043), (34 42 mm, 0.045), improved countermovement jump height (30.7 5.5 cm 29.8 5.8 cm, 0.014) Conclusion: Four supplementation is promising hydration strategy for promoting Clinical Trial Registration: clinicaltrials.gov identifier NCT05799911

Can molecular hydrogen supplementation enhance physical performance in healthy adults? A systematic review and meta-analysis

Frontiers in Nutrition, Journal Year: 2024, Volume and Issue: 11

Published: June 5, 2024

Background Physical exertion during exercise often leads to increased oxidative stress and inflammatory responses, significantly affecting physical performance. Current strategies mitigate these effects are limited by their effectiveness potential side effects. Molecular hydrogen (H₂) has gained attention for its antioxidant anti-inflammatory properties. Studies have suggested that H 2 supplementation contributes anti-fatigue exercise, but the variance in observations study protocols is presented across those studies. Objective This systematic review meta-analysis aimed comprehensively characterize of H₂ on performance (i.e., endurance, muscular strength, explosive power), providing knowledge can inform using enhancing Methods We conducted a literature search six databases (PubMed, Web Science, Medline, Sport-Discus, Embase, PsycINFO) according PRISMA guidelines. The data were extracted from included studies converted into standardized mean difference (SMD). After that, we performed random-effects meta-analyses used I statistic evaluate heterogeneity. Grading Recommendations Assessment, Development, Evaluation (GRADE) was assess quality evidence obtained this meta-analysis. Results In total, 27 publications consisting 597 participants included. finally aerobic anaerobic lower limb power, rating perceived (RPE), blood lactate (BLA), average heart rate (HR avg ) effect size (ES) synthesis.

Hydrogen-Rich Water to Enhance Exercise Performance: A Review of Effects and Mechanisms

Metabolites, Journal Year: 2024, Volume and Issue: 14(10), P. 537 - 537

Published: Oct. 7, 2024

: Hydrogen-rich water (HRW) has garnered significant interest within the sports and exercise science community due to its selective antioxidant properties. Despite potential benefits, comprehensive reviews specifically addressing effects on athletic performance are limited.

Effects of 8 days intake of hydrogen-rich water on muscular endurance performance and fatigue recovery during resistance training

Frontiers in Physiology, Journal Year: 2024, Volume and Issue: 15

Published: Oct. 7, 2024

Background Exercise-induced oxidative stress and inflammation can impair muscular function in humans. The antioxidant anti-inflammatory properties of molecular hydrogen (H 2 ) highlight its potential to be as an effective nutritional supplement support performance healthy adults. However, the effects H supplementation on endurance trained individuals have not been well characterized. This study aimed assess intermittent hydrogen-rich water (HRW) before, during, after resistance training performance, neuromuscular status, subjective perceptual responses a 48-h recovery period. Methods randomized, double-blinded, placebo-controlled cross-over included 18 men aged 19.7 ± 0.9 years. Participants this were instructed consume 1,920 mL HRW or pure (Placebo) daily for 7 days. Additionally, participants required with five times during day (1,260 total). drinking 210 30 min 1 before training, between sets, immediately 420 into performed half-squat exercises load set at 70% one repetition maximum six sets (half-squat exercise repetitions failure each set). We measured power output number free barbell used participants. countermovement jump (CMJ) height, total quality scale (TQRS), muscle soreness visual analog (VAS) scores fatigue status 24 48 h recovery. Results (HRW: 50,866.7 6,359.9W, Placebo: 46,431.0 9,376.5W, p = 0.032) (HRW:78.2 9.5 repetitions, 70.3 0.019) supplemented group significantly higher than placebo group. there was no statistically significant difference (p< 0.05) groups CMJ, TQRS, VAS. Conclusion Eight days intake could improve individuals, making it promising strategy athletes fitness enthusiasts looking boost competitions. should noted that alone may adequate accelerate from following high-intensity training.

Published: Dec. 16, 2024

Background Inhalation of hydrogen gas (H 2 ) as an antioxidant supplement may alleviate exercise-induced oxidative damage and protect post-exercise peroxide signaling, which help mediate beneficial exercise adaptation. The aims this study were to determine the effects H inhalation on plasma nitric oxide (NO) level its synthesis precursor in professional athletes. Methods A randomized, placebo-controlled, double-blind, crossover trial was conducted with male rugby players for 3 weeks. Participants underwent 1 week supplementation placebo treatment prior daily sessions high-intensity training, separated by low-intensity training a washout.
