Effects of Hydrogen-rich Water Consumption on Transient Fatigue During an Official Football Match: Protocol for a Randomised, Double-blind, Placebo-controlled, Parallel-group Trial
Sponsor: Palacky University
Summary
The purpose of this study is to determine whether drinking hydrogen-rich water can reduce fatigue and help football players maintain high-intensity physical activity during an official football match. The study will include 30 male football players competing in the second and third tiers of the Czech national football league system. Participants will be randomly assigned to drink either hydrogen-rich water or placebo water. Neither the players nor the researchers conducting the assessments will know which type of water each participant receives until the study has been completed. Participants will begin drinking the assigned water 72 hours before the match and will continue drinking it on match day. Players' physical activity and heart rate will be monitored throughout the match. The main outcome will be the distance covered at high intensity during consecutive 5-minute periods of the match. Repeated-sprint ability, jumping performance, and perceived muscle soreness will also be assessed before and after the match. The study will compare the hydrogen-rich water and placebo groups to determine whether hydrogen-rich water helps players maintain high-intensity activity during the match and reduces short-term fatigue after the match.

Interventions
Hydrogen-Rich Water (HRW)
Hydrogen-rich water containing 1.2-1.4 ppm dissolved molecular hydrogen (H₂), supplied in gas-tight 420-mL plastic-aluminium packs. Participants will consume 1,260 mL at 72, 48, and 24 hours before the official football match, 840 mL after the pre-match warm-up, and 420 mL during the first half of the match, corresponding to a total intervention volume of 5,040 mL per participant.
Placebo Water
Placebo water containing no dissolved molecular hydrogen (0.0 ppm), supplied in visually identical 420-mL plastic-aluminium packs. The placebo will be administered according to the same volume and timing schedule as the hydrogen-rich water intervention, corresponding to a total intervention volume of 5,040 mL per participant.
