“…Therefore, unlike what happened in untrained subjects, the higher antioxidant and metabolic capacity of trained cyclists, added to the intake of HRW, caused a synergistic effect that allowed them to develop a greater and more lasting effort in anaerobic conditions, reaching higher power levels and lower FI. However, the effects of long-term HRW intake on performance should be specifically evaluated since a decrease in serum ferritin (iron storage/transporter protein in the body) has been observed after inhaling molecular hydrogen for one week [ 18 ]. Furthermore, the circulating ghrelin concentration (its levels increase with HRW intake) has been associated with increased body fat [ 36 ].…”

Hydrogen-rich water (HRW) is used as a supplement to improve performance and reduce fatigue in athletes. However, the potentially beneficial effects of HRW intake could be mediated by the training status of athletes. The purpose of the study was to analyse the ergogenic effect of intake of HRW for one week on aerobic and anaerobic performance, both in trained and untrained individuals. Thirty-seven volunteers participated in the study and were divided into two experimental groups: trained cyclists and untrained subjects. A double-blind crossover design was performed in which all subjects took a placebo (PW) and nano-bubble HRW (pH: 7.5; hydrogen concentration: 1.9 ppm; oxidation-reduction potential (ORP): -600 mV). At the end of 7-day intake, performance was assessed by an incremental VO 2 max test and by a maximum anaerobic test. After HRW intake, only trained cyclists improved their performance in the anaerobic test with an increase in peak power (from 766.2 ± 125.6 to 826.5 ± 143.4 W; d = .51) and mean power (from 350.0 ± 53.5 to 380.2 ± 71.3 W; d = .51), and a decrease in the fatigue index (from 77.6 ± 5.8 to 75.1 ± 5.9%; d = .45). The findings demonstrate that the ergogenic effect of HRW is mediated by the training status, and that 7-day intake of HRW would be an effective strategy for improving anaerobic performance in trained cyclists.

“…HRW supplementation has been shown to have a positive effect on repeated-sprint ability performance, muscle fatigue and ventilatory response [ 14 – 17 ]. Similarly, the inhalation of 4% gaseous hydrogen during a week improved the peak running velocity of physically active men and women [ 18 ].…”

“…H 2 has also been shown to stimulate mitochondrial respiration, Q-cycle [ 25 ], and oxidative ATP phosphorylation (OXOPHOS) rate [ 26 ]. Pre-exercise HRW intake or H 2 inhalation has been shown to have an antifatigue effect across different modes of exercise, including endurance [ 27 , 28 , 29 ], strength-endurance drills [ 30 ], cycling anaerobic power output [ 31 ], maximal isokinetic muscle strength [ 32 ], and during prolonged, intermittent sprints [ 33 ]. H 2 administration strategies varied across studies, e.g., in duration of pre-exercise administration (30 min [ 30 ], 8 h [ 32 ], 24 h [ 28 ], 7 days [ 29 , 31 ], 2 weeks [ 33 ], and 4 weeks [ 27 ]) and administration mode (HRW [ 27 , 28 , 30 , 31 , 32 , 33 ], H 2 inhalation [ 29 ]), which complicates the comparison of the study results.…”

However, there is a paucity of studies examining the antifatigue effect of HRW consumption on subsequent repeated sprint performance in team sport in general, and specifically in professional soccer.…”

Hydrogen-rich water (HRW) supplementation has been shown to have an antifatigue effect across different modes of exercise. However, its effect on repeated sprint performance is unknown. The aim of this study was to assess the effect of pre-exercise HRW consumption on repeated sprint performance, lactate, and perceptual responses using a repeated sprint protocol. This randomized, double blinded, placebo controlled, crossover study included 16 professional, male soccer players aged 18.8 ± 1.2 years. Athletes performed two indoor tests, particularly 15 × 30 m track sprints interspersed by 20 s of recovery, separated by a 1-week washout period. Sprint time was measured at 15 m and 30 m. Ratings of perceived exertion were assessed immediately after each sprint, and post-exercise blood lactate concentration was measured after the last sprint. There were significantly faster sprint times after HRW consumption compared with placebo at 15 m for the 14th and 15th sprints, representing improvements in time of 3.4% and 2.7%, respectively. Sprint time at 30 m also significantly improved by 1.9% in the HRW group in the last sprint. However, neither lactate concentrations nor ratings of perceived exertion were significantly different between HRW and placebo. Pre-exercise HRW supplementation is associated with an increased ability to reduce fatigue, especially during the later stages of repeated sprint exercise.

“…Molecular hydrogen (H 2 ) has been shown to be a healthy, safe gas [ 20 ] with a strong and selective antioxidative capability for scavenging the harmful hydroxyl radical and peroxynitrite anion [ 20 , 21 ]. Numerous studies have indicated that H 2 has anti-inflammatory [ 22 ], anti-apoptosis [ 23 ], antifatigue [ 24 , 25 , 26 , 27 ], and regulatory properties [ 28 ]. Based on the reported beneficial health effects across a variety of diagnoses [ 22 , 29 ], H 2 administration has recently been proposed as a promising therapeutic gas for COVID-19 patients [ 7 , 30 , 31 , 32 , 33 , 34 , 35 ].…”

Molecular hydrogen (H2) is potentially a novel therapeutic gas for acute post-coronavirus disease 2019 (COVID-19) patients because it has antioxidative, anti-inflammatory, anti-apoptosis, and antifatigue properties. The aim of this study was to determine the effect of 14 days of H2 inhalation on the respiratory and physical fitness status of acute post-COVID-19 patients. This randomized, single-blind, placebo-controlled study included 26 males (44 ± 17 years) and 24 females (38 ± 12 years), who performed a 6-min walking test (6 MWT) and pulmonary function test, specifically forced vital capacity (FVC) and expiratory volume in the first second (FEV1). Symptomatic participants were recruited between 21 and 33 days after a positive polymerase chain reaction test. The experiment consisted of H2/placebo inhalation, 2 × 60 min/day for 14 days. Results showed that H2 therapy, compared with placebo, significantly increased 6 MWT distance by 64 ± 39 m, FVC by 0.19 ± 0.24 L, and, in FEV1, by 0.11 ± 0.28 L (all p ≤ 0.025). In conclusion, H2 inhalation had beneficial health effects in terms of improved physical and respiratory function in acute post-COVID-19 patients. Therefore, H2 inhalation may represent a safe, effective approach for accelerating early function restoration in post-COVID-19 patients.
