Hydrogen-Rich Water to Enhance Exercise Performance: A Review of Effects and Mechanisms (2024)

Study Synopsis

Hydrogen-rich water (HRW) has attracted growing interest among athletes, coaches, and researchers due to its potential to support exercise performance, recovery, and resistance to fatigue. In this 2024 scientific review, researchers examined the available evidence regarding hydrogen-rich water and athletic performance while also exploring the molecular mechanisms that may explain its effects.

The review evaluated studies involving endurance exercise, high-intensity exercise, muscle fatigue, recovery, oxidative stress, and exercise-related metabolic responses.

What Is a Review Article?

Unlike a single experiment, a review article analyzes and summarizes findings from numerous previously published studies. Review papers are valuable because they provide a broader understanding of the evidence and help identify consistent patterns across multiple investigations.

The authors noted that hydrogen-rich water has demonstrated promising effects in several areas of athletic performance, although not all studies have reported the same results.

Key Findings From the Review

Reduced Exercise-Induced Fatigue

Multiple studies reviewed by the authors reported reductions in exercise-induced fatigue following hydrogen-rich water supplementation. Several investigations found that athletes consuming hydrogen-rich water experienced improved performance during repeated bouts of exercise and demonstrated a slower decline in physical output during demanding activities.

Improved Recovery Following Exercise

The review highlighted evidence suggesting that hydrogen-rich water may support post-exercise recovery by reducing markers associated with exercise stress and muscle damage. Several studies reported improvements in recovery measures following intense training sessions.

Lower Lactate Accumulation

Research summarized in the review found that hydrogen-rich water may reduce blood lactate accumulation during exercise. Because elevated lactate is often associated with high-intensity effort and fatigue, this finding has attracted significant interest within sports science.

Enhanced Antioxidant Capacity

Exercise increases the production of reactive oxygen species (ROS), which contribute to oxidative stress. The review noted that molecular hydrogen may help support the body’s antioxidant defense systems while maintaining normal cellular signaling processes.

Potential Benefits for Explosive Power

Some studies reviewed by the authors reported improvements in explosive power and high-intensity exercise performance. These findings suggest hydrogen-rich water may be particularly relevant for sports requiring repeated bursts of power and rapid recovery.

Proposed Mechanisms

The review discussed several potential mechanisms through which molecular hydrogen may influence exercise performance.

Oxidative Stress Regulation

Molecular hydrogen has been shown to selectively interact with highly reactive oxidants while preserving beneficial signaling molecules. This may help maintain a healthier balance between exercise adaptation and excessive oxidative stress.

Anti-Inflammatory Effects

Research suggests molecular hydrogen may help regulate inflammatory pathways activated during strenuous exercise. This mechanism may contribute to improved recovery following training and competition.

Mitochondrial Support

The authors reviewed evidence suggesting molecular hydrogen may influence mitochondrial function and cellular energy production. Because mitochondria play a central role in exercise performance, this remains an important area for future research.

What the Review Found About Endurance Performance

While several studies reported favorable effects on fatigue, recovery, and power output, evidence for improvements in aerobic endurance remains mixed.Some studies reported benefits, while others found little or no improvement in measures such as aerobic capacity and endurance performance. The authors concluded that additional high-quality human trials are needed to better understand which athletes are most likely to benefit from hydrogen-rich water supplementation.

Why This Review Matters

This review is important because it evaluates the athletic performance literature as a whole rather than focusing on a single experiment. The overall evidence suggests that hydrogen-rich water may offer the greatest potential benefits in:

  • Exercise recovery
  • Fatigue management
  • Lactate regulation
  • Oxidative stress balance
  • High-intensity and explosive exercise performance

However, the review also emphasizes that additional research is needed to clarify its effects on aerobic endurance and long-term athletic adaptation.

Practical Takeaway

Current evidence suggests hydrogen-rich water may help support:

  • Recovery between training sessions
  • Resistance to exercise-induced fatigue
  • Lactate clearance
  • Antioxidant defenses
  • High-intensity exercise performance

The strongest evidence currently appears to support recovery and fatigue-related benefits, while evidence for improvements in aerobic endurance remains less consistent.

Hydrogen-Rich Water Reduces Delayed Onset Muscle Soreness (DOMS) After Resistance Training (2022)

Study Synopsis

Delayed onset muscle soreness (DOMS) is a common consequence of intense exercise and resistance training. Muscle soreness, reduced performance, and elevated lactate levels can negatively impact recovery and readiness for subsequent training sessions. Researchers investigated whether supplementation with hydrogen-rich water (HRW) could improve muscle performance, reduce lactate accumulation, and alleviate delayed onset muscle soreness following resistance exercise.

The study found that participants consuming hydrogen-rich water experienced significantly less muscle soreness after training, lower lactate levels, and improved measures of muscle performance compared with placebo.

Study Design

Researchers conducted a randomized, placebo-controlled, double-blind crossover study involving healthy physically active adults. Participants completed resistance exercise testing under both hydrogen-rich water and placebo conditions.

Researchers evaluated:

  • Muscle performance
  • Blood lactate response
  • Delayed onset muscle soreness (DOMS)
  • Recovery following resistance exercise

The crossover design allowed each participant to serve as their own control, strengthening the reliability of the findings.

Key Findings

Reduced Delayed Onset Muscle Soreness

Participants consuming hydrogen-rich water reported significantly lower levels of muscle soreness during recovery following resistance exercise. Twenty-four hours after exercise, DOMS scores were substantially lower in the hydrogen-rich water group compared with placebo.

Lower Lactate Response

Hydrogen-rich water supplementation reduced post-exercise blood lactate concentrations.

Lower lactate accumulation may reflect improved metabolic efficiency and recovery following intense exercise.

Improved Muscle Performance

Researchers observed improvements in muscle performance measurements among participants receiving hydrogen-rich water.

The findings suggest that hydrogen-rich water may help athletes maintain performance while supporting recovery after strenuous training.

Why This Study Matters

Many athletes and active individuals experience muscle soreness that can interfere with training consistency and recovery. This study is notable because it demonstrated benefits in three areas that are highly relevant to athletes:

  • Reduced muscle soreness
  • Lower lactate accumulation
  • Improved muscle performance

These outcomes suggest that hydrogen-rich water may be a valuable tool for supporting recovery after resistance training and high-intensity exercise.

Practical Takeaway

For athletes, fitness enthusiasts, and active individuals, this research suggests that hydrogen-rich water may help:

  • Reduce delayed onset muscle soreness (DOMS)
  • Support faster recovery after exercise
  • Lower exercise-induced lactate accumulation
  • Maintain muscle performance following strenuous training

These benefits may be especially valuable during periods of intense training, competition, or frequent exercise sessions.

Study Limitations

As with all studies, several limitations should be considered:

  • Modest sample size
  • Short-term supplementation period
  • Physically active participants rather than elite athletes
  • Additional research is needed to confirm findings across broader populations

Despite these limitations, the study provides encouraging evidence that hydrogen-rich water may support exercise recovery and reduce post-exercise muscle soreness.

Pre-Exercise Ingestion of Hydrogen-Rich Cold Water Enhances Endurance Performance and Lactate Response in Heat

This 2025 randomized, double-blind crossover study examined whether drinking hydrogen-rich cold water (HRCW) before exercise could improve endurance performance and reduce heat stress during exercise in hot conditions. Twenty-two trained male sports science students completed shuttle run tests in 32 °C heat under three conditions:

  • hydrogen-rich cold water (HRCW),
  • cold water alone,
  • and cold water combined with external cooling.

Researchers found that pre-exercise ingestion of 500 mL of hydrogen-rich cold water significantly improved endurance performance compared to cold water alone. Participants consuming HRCW showed:

  • a 4.8% increase in maximal aerobic speed (MAS),
  • more than 20% more shuttle run repetitions,
  • lower blood lactate levels,
  • reduced dehydration,
  • lower perceived exertion,
  • improved mood scores,
  • and reduced post-exercise body temperature.

Interestingly, the combination of external cooling and cold water lowered body temperature but did not improve performance as effectively as hydrogen-rich cold water alone. Researchers suggest that molecular hydrogen may provide benefits beyond simple cooling by helping reduce oxidative stress and support mitochondrial energy production during exercise in the heat.

The paper discusses several possible mechanisms by which molecular hydrogen may improve endurance performance, including:

  • selective reduction of harmful reactive oxygen species,
  • improved mitochondrial ATP production,
  • enhanced antioxidant defenses,
  • improved metabolic efficiency,
  • and reduced neuromuscular fatigue.

Researchers also observed significantly lower blood lactate concentrations after exercise in the HRCW condition, suggesting improved metabolic coordination and reduced exercise stress during heat exposure.

In everyday language, this study suggests that drinking hydrogen-rich cold water before exercise in hot conditions may help athletes maintain endurance, reduce heat stress, improve comfort, and recover more efficiently during intense activity.

The authors conclude that hydrogen-rich cold water may serve as an effective pre-cooling and performance-support strategy for exercise in hot environments.

Mechanism by Which Hydrogen-Rich Water Mitigates Exercise-Induced Fatigue

This 2026 study published in Medical Gas Research explored how hydrogen-rich water (HRW) reduces exercise fatigue at the molecular level. Researchers used a forced-swimming mouse model combined with metabolomics, oxidative stress testing, muscle tissue analysis, and cellular experiments to investigate the biological pathways involved. The study found that hydrogen-rich water significantly improved exercise endurance and recovery in fatigued mice. HRW:

  • increased treadmill running distance,
  • improved rotarod performance,
  • reduced blood lactate,
  • lowered blood urea nitrogen (BUN),
  • reduced creatine kinase (CK),
  • preserved muscle glycogen,
  • and reduced visible muscle fiber damage.

One of the most important findings was the identification of a specific anti-fatigue signaling pathway activated by HRW:

IRG1 → Itaconate → Nrf2 → HO-1

The researchers discovered that hydrogen-rich water increased expression of:

  • IRG1 (Immunoresponsive Gene 1),
    which increased production of:
  • Itaconate, a natural metabolic signaling molecule,
    which then activated:
  • Nrf2, the body’s master antioxidant response regulator,
    leading to increased:
  • HO-1 (Heme Oxygenase-1),
    a protective antioxidant and anti-inflammatory enzyme.

The paper concludes that this pathway helps reduce oxidative stress caused by strenuous exercise and improves recovery from fatigue. The graphical abstract on page 1 visually summarizes this cascade and its role in reducing oxidative stress in muscle tissue.

The study also showed:

  • lower oxidative stress markers (malondialdehyde),
  • increased antioxidant enzyme activity (SOD and glutathione peroxidase),
  • improved mitochondrial function,
  • and reduced reactive oxygen species (ROS) in muscle cells treated with HRW.

Importantly, the authors suggest that hydrogen-rich water does not merely “neutralize free radicals” directly. Instead, it appears to activate the body’s own endogenous antioxidant defense systems through metabolic signaling pathways. That distinction is scientifically important because it may explain why molecular hydrogen shows broad protective effects across multiple physiological systems.

In everyday language, this paper suggests that hydrogen-rich water may help the body:

  • recover faster from physical stress,
  • preserve muscle energy,
  • reduce oxidative damage,
  • support mitochondrial performance,
  • and activate natural cellular recovery pathways during intense exercise or fatigue states.

The authors conclude that hydrogen-rich water may represent a practical, low-toxicity strategy for improving exercise recovery and reducing fatigue-related oxidative stress.

Effects of Hydrogen-Rich Water on Prolonged Intermittent Exercise

This 2018 study investigated whether drinking hydrogen-rich water (HRW) could improve performance and reduce fatigue during repeated high-intensity intermittent exercise similar to many team sports. Researchers tested trained soccer players performing repeated sprint and endurance activities after consuming hydrogen-rich water for 7 days.

The study found that hydrogen-rich water significantly reduced declines in peak power during repeated exercise sessions. Athletes consuming HRW maintained better performance output and showed signs of reduced muscular fatigue compared to placebo.

Researchers observed:

  • improved repeated sprint performance,
  • reduced fatigue accumulation,
  • preservation of peak power output,
  • and lower physiological stress during prolonged intermittent exercise.

The paper discusses how molecular hydrogen may help by:

  • reducing oxidative stress generated during intense exercise,
  • improving mitochondrial efficiency,
  • lowering muscle fatigue,
  • and helping the body maintain energy production during repeated exertion.

Importantly, the authors noted that the benefits appeared most pronounced during prolonged, repeated bursts of exercise rather than short single efforts. This aligns well with sports involving repeated sprinting, rapid recovery demands, and sustained high workloads such as soccer, basketball, football, hockey, and combat sports.

In everyday language, this study suggests that hydrogen-rich water may help athletes maintain performance longer during demanding workouts or sports where fatigue normally builds over time.

The findings support growing research that molecular hydrogen may improve exercise tolerance and recovery by reducing oxidative damage and helping muscles function more efficiently under stress.

Effect of Molecular Hydrogen Application on Recovery After Endurance Running in Untrained Men

This 2025 randomized, double-blind, placebo-controlled crossover study examined whether hydrogen-rich water (HRW) could improve recovery after a 5 km endurance run in untrained men aged 20–30 years. Sixteen participants completed two separate 5 km runs spaced 7 days apart while consuming either HRW or placebo water. Participants consumed a total of 3780 mL of HRW, including a prophylactic dose before exercise and an additional dose after the running protocol. Researchers evaluated post-exercise muscle soreness using a Visual Analog Scale (VAS) and measured explosive lower-body power using countermovement jump (CMJ) testing.

The study found that HRW significantly reduced delayed onset muscle soreness (DOMS) at:

  • 1 hour post-exercise (p = 0.005)
  • 4 hours post-exercise (p = 0.002)
  • 24 hours post-exercise (p = 0.016)

Although HRW reduced muscle soreness, researchers did not observe statistically significant improvements in explosive lower-body power measured by vertical jump performance. However, the data suggested a relationship between reduced soreness and improved recovery dynamics after exercise. The paper also reviews earlier human studies showing that molecular hydrogen may help reduce exercise-induced oxidative stress, fatigue, and muscle soreness following endurance and high-intensity exercise.

In everyday language, the research suggests that hydrogen-rich water may help reduce post-exercise muscle soreness and improve recovery comfort after endurance exercise, particularly in individuals who are not endurance-trained.

The authors conclude that HRW may represent a useful recovery strategy for reducing exercise-induced muscle soreness in recreational or untrained individuals following endurance running.
