Can molecular hydrogen supplementation enhance physical performance in healthy adults? A systematisk översikt and metaanalys
27 studies (n=597) found hydrogen supplementation improved lower-limb explosive power and reduced perceived exertion, but had no effect on aerobic endurance, anaerobic endurance, or muscular strength.
En meta-analys från 2024 av 27 publikationer (597 deltagare) utvärderade tillskott av molekylärt väte för fysisk prestation. H2 förbättrade explosiv kraft i nedre extremiteterna (SMD=0.30, p=0.018, I2=0 %), minskade rating of perceived exertion under träning (SMD=-0.37, p=0.009, I2=58.0 %) och minskade blodlaktat (SMD=-0.37, p=0.001, I2=22.0 %). However, H2 showed no significant effect on VO2max (SMD=0.09, p=0.394), aerobic endurance exercise (SMD=0.04, p=0.687), 30-second anaerobic endurance (SMD=0.19, p=0.239), or muscular strength (SMD=0.19, p=0.265). All non-significant effects were trivial in magnitude. H2 was administered as hydrogen-rich water, hydrogen bathing, or hydrogen-rich gas.
These findings suggest that H2 supplementation is favorable in healthy adults to improve lower limb explosive power, alleviate fatigue, and boost BLA clearance, but may not be effectively improving aerobic and anaerobic endurance and muscular strength. Future studies with more rigorous designs are thus needed.
Small overall sample (597 across 27 studies = ~22 participants per study). High heterogeneity for perceived exertion (I2=58%). Most studies from the same research network. No long-term outcomes measured. Effect sizes are small even where significant.
