Drinking hydrogen water enhances ENDURANCE and relieves psychometric FATIGUE: a randomized, double-blind, placebo-controlled study 

Drinking hydrogen water enhances endurance and relieves psychometric fatigue: a randomized, double-blind, placebo-controlled study

Abstract

Acute physical exercise increases reactive oxygen species in skeletal muscle, leading to tissue damage and fatigue. Molecular hydrogen (H2) acts as a therapeutic antioxidant directly or indirectly by inducing antioxidative enzymes.

Here, we examined the effects of drinking hydrogen H2 water (H2-infused water) on psychometric fatigue and endurance capacity in a randomized, double-blind, placebo-controlled fashion.

In Experiment 1, all participants(humans) drank only placebo water in the first cycle ergometer exercise session, and for comparison they drank either hydrogen H2 water or placebo water 30 min before exercise in the second examination.In these healthy non-trained participants (n = 99), psychometric fatigue judged by visual analogue scales was significantly decreased in the hydrogen H2 water group after mild exercise. When each group was divided into 2 subgroups, the subgroup with higher visual analogue scale values was more sensitive to the effect of hydrogen water H2.

In Experiment 2, trained participants (n = 60) were subjected to moderate exercise by cycle ergometer in a similar way as in Experiment 1, but exercise was performed 10 min after drinking hydrogen H2 water. Endurance/fatigue were significantly improved/relieved in the hydrogen water H2 group as judged by maximal oxygen consumption and Borg’s scale, respectively.

Taken together, drinking hydrogen H2 water just before exercise exhibited anti-fatigue and improved endurance effects.

Effects of hydrogen rich water on prolonged intermittent EXERCISE

BACKGROUND:
Recent studies showed a positive effect of hydrogen rich water (HRW) intake on acid-base homeostasis at rest. We investigated 2-weeks of hydrogen rich water HRW intake on repeated sprint performance and acid-base status during prolonged intermittent cycling exercise.

METHODS:
In a cross over single-blind protocol, 8 trained male cyclists (age [mean±SD] 41±7 years, body mass 72.3±4.4 kg, height 1.77±0.04 m, maximal oxygen uptake [V̇O2max] 52.6±4.4 mL·kg-1·min-1) were provided daily with 2 liters of placebo normal water (PLA, pH 7.6, oxidation/reduction potential [ORP] +230 mV, free hydrogen content 0 ppb) or hydrogen rich water HRW (pH 9.8, ORP -180 mV, free Hydrogen 450 ppb). Tests were performed at baseline and after each period of 2 weeks of treatment. The treatments were counter-balanced and the sequence randomized. The 30-minute intermittent cycling trial consisted in 10 3-minute blocks, each one composed by 90 seconds at 40% V̇O2max, 60 seconds at 60% V̇O2max, 16 seconds all out sprint, and 14 seconds active recovery. Oxygen uptake (V̇O2), heart rate and power output were measured during the whole test, while mean and peak power output (PPO), time to peak power and Fatigue Index (FI) were determined during all the 16 seconds sprints. Lactate, pH and bicarbonate (HCO3-) concentrations were determined at rest and after each sprint on blood obtained by an antecubital vein indwelling catheter.

RESULTS:
In the PLA group, PPO in absolute values decreased significantly at the 8th and 9th of 10 sprints and in relative values, ΔPPO, decreased significantly at 6th, 8th and 9th of 10 sprints (by mean: -12±5%, P<0.006), while it remained unchanged in hydrogen rich water HRW group. Mean power, FI, time to peak power and total work showed no differences between groups. In both conditions lactate levels increased while pH and HCO3- decreased progressively as a function of the number of sprints.

CONCLUSIONS:
Two weeks of hydrogen rich water HRW intake may help to maintain PPO in repetitive sprints to exhaustion over 30 minutes.
