About this study
Official title: 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
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.
Read the detailed description
Fatigue during football match play may reduce players' ability to maintain high-intensity activity, particularly following demanding periods of play and during the later stages of a match. The mechanisms contributing to fatigue are multifactorial and include metabolic, neuromuscular, and perceptual factors. Exercise-induced changes in redox homeostasis may also contribute to impaired skeletal muscle function during strenuous exercise.
Molecular hydrogen has been investigated as a potential strategy for supporting exercise performance and recovery because of its proposed effects on redox homeostasis, inflammatory pathways, and mitochondrial function. Hydrogen-rich water (HRW) provides a practical method of molecular hydrogen administration. Previous studies have reported potential effects of HRW on exercise-related outcomes, including blood lactate responses, perceived exertion, muscle soreness, and the maintenance of performance during repeated high-intensity exercise. However, evidence remains inconsistent, and it is currently unclear whether these effects translate to competitive football match play.
This study will therefore investigate whether HRW consumption influences the development of transient fatigue during an official football match. Particular attention will be given to changes in high-intensity running activity throughout the match. Continuous monitoring will allow match activity to be examined in consecutive 5-minute periods and between the first and second halves. This approach is intended to determine whether the temporal pattern of high-intensity activity differs between players receiving HRW and those receiving placebo.
In addition to match running performance, internal load and acute post-match fatigue will be evaluated. Heart rate responses will be monitored throughout the match, while repeated-sprint ability, countermovement jump performance, and perceived lower-limb muscle soreness will be assessed before and immediately after match play. Together, these measures will provide complementary information about external load, internal load, and acute neuromuscular and perceptual responses to competitive match play.
The study is intended to determine whether the effects of molecular hydrogen previously observed under controlled exercise conditions are also evident under the complex physiological and contextual demands of an official football match.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Hydrogen-Rich Water (HRW)Dietary supplement
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 WaterDietary supplement
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.
| Study group | Role | What they receive |
|---|---|---|
| Hydrogen-Rich Water (HRW) | Experimental | Participants assigned to this arm will consume hydrogen-rich water (HRW) containing 1.2-1.4 ppm dissolved molecular hydrogen. Participants will consume 1,260 mL (three 420-mL packs) at 72, 48, and 24 hours before the official football match, 840 mL (two 420-mL packs) after the pre-match warm-up, and 420 mL (one 420-mL pack) during the first half of the match.

| Placebo water | Placebo comparator | Participants assigned to this arm will consume placebo water containing no dissolved molecular hydrogen (0.0 ppm). The placebo will be provided in visually identical 420-mL packs and administered according to the same supplementation schedule as the HRW intervention: 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. Receives: Dietary Supplement: Placebo Water |
What is being measured
The primary outcome is the main question the study is designed to answer.
High-Intensity Distance During Match Play
High-intensity distance (HID), defined as the distance covered at running speeds >14.4 km·h-¹, will be measured continuously during an official football match using a 10-Hz global positioning system (GPS; Vector S7, Catapult Sports, Melbourne, Australia). HID will be quantified in metres for consecutive 5-minute intervals throughout match play. The temporal pattern of HID will be compared between the hydrogen-rich water and placebo groups.
Measured: During the official football match (consecutive 5-minute intervals, up to 90 minutes)
Secondary outcomes (6)
Total Distance During Match Play
Total distance (TD), expressed in metres, will be measured continuously using a 10-Hz GPS system and quantified in consecutive 5-minute intervals throughout the official football match.
Measured: During the official football match (consecutive 5-minute intervals, up to 90 minutes)
PlayerLoad During Match Play
PlayerLoad will be measured continuously using the triaxial accelerometer integrated within the Catapult Vector S7 system and quantified in consecutive 5-minute intervals throughout match play.
Measured: During the official football match (consecutive 5-minute intervals, up to 90 minutes)
Top Speed During Match Play
Top speed, expressed in km·h-¹, will be determined using the 10-Hz GPS system during the official football match.
Measured: During the official football match (up to 90 minutes)
Heart Rate During Match Play
Heart rate will be recorded continuously and expressed relative to each participant's individual peak heart rate (HRpeak). Heart rate responses will be evaluated in consecutive 5-minute intervals.
Measured: During the official football match (consecutive 5-minute intervals, up to 90 minutes)
Repeated-Sprint Ability
Repeated-sprint ability will be assessed using five 20-m sprints starting every 20 seconds. Performance will be expressed as total sprint time (sum of the five sprints). Acute match-induced fatigue will be evaluated as the pre- to post-match change in total sprint time.
Measured: Pre-match and immediately post-match
Countermovement Jump Performance
Countermovement jump performance will be assessed using an OptoJump system. Acute match-induced neuromuscular fatigue will be evaluated as the pre- to post-match change in jump performance.
