A recent study published in Research in Sports Medicine explored the effects of hydrogen-rich water on exercise-related biomarkers in previously untrained middle-aged adults. Researchers from the University of Novi Sad in Serbia conducted a randomized controlled pilot trial involving 27 adults aged 50 to 65, who were divided into two groups - one consuming hydrogen-rich water and the other regular water placebo for six weeks. Both groups participated in supervised resistance training sessions two to three times per week. The study found that while muscular performance did not significantly improve compared to the control group, the group drinking hydrogen-rich water showed a significant reduction in biomarkers of acute muscular damage. Furthermore, the hydrogen-rich water group exhibited beneficial hormonal responses, including small increases in free testosterone and cortisol levels, along with improvements in sleep quality. These outcomes indicate that hydrogen-rich water may help middle-aged adults new to exercise better cope with muscle damage from resistance training. Hydrogen-rich water is regular water infused with molecular hydrogen gas, believed to possess antioxidant properties that neutralize free radicals and reduce oxidative stress. The researchers highlighted the importance of further studies in broader populations to validate the findings and elucidate hydrogen's mechanisms at the molecular level. They also emphasized the need for well-controlled trials to explore the long-term safety and efficacy of hydrogen-rich water across different populations and types of physical activity. The study suggests that hydrogen-rich water could be a safe and beneficial beverage option for older exercise-naïve individuals, potentially aiding in training-specific adaptations. Overall, the research adds to the growing body of evidence supporting the potential of hydrogen-rich water in supporting exercise adaptation and reducing muscle damage in middle-aged adults embarking on fitness programs.
