剧烈的体育锻炼会增加骨骼肌中的活性氧，导致组织损伤和疲劳。分子氢（H-2）通过诱导抗氧化酶直接或间接地作为治疗性抗氧化剂。在这里，我们以随机、双盲、安慰剂对照的方式研究了饮用H-2水（注入H-2的水）对心理测量疲劳和耐力的影响。在实验1中，所有参与者在第一次自行车测力计运动中只喝安慰剂水，为了比较，他们在第二次检查中运动前30分钟喝H-2水或安慰剂水。在这些健康的非训练的参与者（n = 99），视觉模拟量表判断的心理测量疲劳显着降低H-2组轻度运动后。当每组分为2个亚组时，视觉模拟量表值较高的亚组对H-2的作用更敏感。在实验2中，训练的参与者（n = 60）进行适度的运动自行车测力计以类似的方式在实验1中，但运动后10分钟饮用H-2水。分别通过最大耗氧量和博格量表判断，H-2组的耐力和疲劳显著改善。总之，在运动前饮用H-2水表现出抗疲劳和耐力的效果。
Acute physical exercise increases reactive oxygen species in skeletal muscle, leading to tissue damage and fatigue. Molecular hydrogen (H-2) acts as a therapeutic antioxidant directly or indirectly by inducing antioxidative enzymes. Here, we examined the effects of drinking H-2 water (H-2-infused water) on psychometric fatigue and endurance capacity in a randomized, double-blind, placebo-controlled fashion. In Experiment 1, all participants drank only placebo water in the first cycle ergometer exercise session, and for comparison they drank either H-2 water or placebo water 30 min before exercise in the second examination. In these healthy non-trained participants (n = 99), psychometric fatigue judged by visual analogue scales was significantly decreased in the H-2 group after mild exercise. When each group was divided into 2 subgroups, the subgroup with higher visual analogue scale values was more sensitive to the effect of H-2. In Experiment 2, trained participants (n = 60) were subjected to moderate exercise by cycle ergometer in a similar way as in Experiment 1, but exercise was performed 10 min after drinking H-2 water. Endurance and fatigue were significantly improved in the H-2 group as judged by maximal oxygen consumption and Borg's scale, respectively. Taken together, drinking H-2 water just before exercise exhibited anti-fatigue and endurance effects.
