Acute Supplementation with Molecular Hydrogen Benefits Submaximal Exercise Indices. Randomized, Double-Blinded, Placebo-Controlled Crossover Pilot Study.

Acute Supplementation with Molecular Hydrogen Benefits Submaximal Exercise Indices. Randomized, Double-Blinded, Placebo-Controlled Crossover Pilot Study.

BACKGROUND: Clinical studies have reported hydrogen-rich water (HRW) to have therapeutic and ergogenic effects. The aim of this study was to determine the effect of acute supplementation with HRW on exercise performance as measured by VO2, respiratory exchange ratio (RER), heart rate (HR), and respiratory rate (RR). METHODS: Baseline levels of all exercise indices were determined in nineteen (4 female, 23.4 ± 9.1 yr; 15 male, 30.5 ± 6.8 yr) healthy subjects using a graded treadmill exercise test to exhaustion. Each subject was examined two additional times in a randomized double-blinded, placebo-controlled crossover fashion. Subjects received either HRW or placebo,...

Short-term H2 inhalation improves running performance and torso strength in healthy adults

Short-term H2 inhalation improves running performance and torso strength in healthy adults

   In this randomized, double-blind, placebo-controlled, crossover pilot trial, we evaluated the effects of 7-day H2 inhalation on exercise performance outcomes and serum hormonal and inflammation profiles in a cohort of young men and women. All participants (age 22.9 ± 1.5 years; body mass index 23.4 ± 2.5 kg m-2; 10 women and 10 men) were allocated to receive either gaseous hydrogen (4%) or placebo (room air) by 20-min once-per-day inhalation for 7 days, with a wash-out period of 7 days to prevent the residual effects of interventions across study periods. The primary treatment outcome was the change in running time-to-exhaustion...

Hydrogen-Rich Water Supplementation and Up-Hill Running Performance: Effect of Athlete Performance Level

Hydrogen-Rich Water Supplementation and Up-Hill Running Performance: Effect of Athlete Performance Level

Hydrogen-rich water (HRW) has been shown to have an antifatigue effect. This study assessed up-hill running performance, as well as physiological and perceptual responses after supplementation with 1680 mL HRW between 24 h and 40 min before running, in athletes of heterogeneous running ability. Methods: Sixteen males (mean [SD] age 31.6 [8.6] y, VO2max 57.2 [8.9] mL·kg−1·min−1, body fat 13.4% [4.4%]) participated in this study. Using a randomized, double-blind, placebo-controlled crossover design, participants consumed either HRW or placebo prior to performing two 4.2-km up-hill races separated by a week. Race time (RT), average race heart rate, and immediately postrace rating...

Successful treatment with hydrogen rich water in a case of chronic graft-versus-host-disease.

Successful treatment with hydrogen rich water in a case of chronic graft-versus-host-disease.

Abstract The incidence of chronic graft-versus-host-disease is rising year by year, which has become the leading cause of non-transplantation related death and has become the most difficult complication of allogeneic hematopoietic stem cell transplantation to deal with. Inflammation and fibrosis play dominant roles in the pathogenesis of chronic graft-versus-host-disease. Studies have shown that molecular hydrogen has anti-inflammatory, antioxidant, anti-fibrosis effects. Therefore, we hypothesized that molecular hydrogen may have therapeutic effects on chronic graft-versus-host-disease. Here, we report a patient with severe chronic graft-versus-host-disease successfully treated by drinking hydrogen rich water which may be a safe and effective method for chronic graft-versus-host-disease....
