Molecular Hydrogen Inhalation: Effects on Health, Exercise Capacity and Inflammatory Response - in Vivo/in Vitro Studies

"Hydrogen inhalation will be performed by using a hydrogen gas generator similar in terms of capabilities to the generator Hycellvator ET100 (Helix Japan, Co., Ltd., Tokyo, Japan). The apparatus will be generating 30.0 mL/s gas mixture, consisting of 68.0% hydrogen (hydrogen purity, 99.99%) and 32.0% of oxygen. All gases will be supplied through a nasal cannula connected to the gas generators. Although we could not measure directly the hydrogen and oxygen An average inspiratory flow rate will be adjusted to 500 mL/s at rest, the hydrogen concentration in the inspired gas must have been around 4.08% at most.~Control population will have inhalation with the use of gas generator that has the same outer shape as the used generator to produce Placebo (30.0 mL/s, ambient air 400 m above sea level) consisting of 0.00005% of hydrogen and 20.9% of oxygen."
