摘　　要：背景:氢气可以减轻剧烈运动引起的氧化应激,改善疲劳状况。目前已有一些研究报道,摄入富氢水或富氢气体对改善运动性疲劳和运动表现有潜在效果。目的:探究高强度运动前吸入富氢气体对运动疲劳后本体感觉和肌肉耐力表现的影响。方法:通过随机、双盲、交叉、重复测量的试验设计,将24名健康成年男子随机分为A、B组,每组12名,在交叉前的试验第一阶段分别吸入20 min富氢气体和安慰剂气体(空气),随后使用功率车建立疲劳模型,在吸气前和疲劳后进行疲劳目测类比评分、心率变异性、膝关节本体感觉(被动位置觉、关节运动觉和肌肉力觉)和伸膝等长肌肉耐力测试。经过7 d洗脱期后,在试验第二阶段两组交换干预方案并进行上述测试。分别对比2个阶段中A、B组结果的差异,并整合两阶段结果,对比氢气和安慰剂干预的差异。结果与结论:(1)在试验的第一阶段,氢气组干预后的疲劳目测类比评分低于安慰剂组(P <0.01),相邻R-R间期差值均方根、低频输出功率均值、高频输出功率均值和等长肌肉耐力值均大于安慰剂组(P <0.05),被动位置觉和关节运动觉优于安慰剂组(P <0.05),两组间肌肉力觉比较差异无显著性意义(P> 0.05),安慰剂组干预后的肌肉力觉差于干预前(P <0.01)。在试验的第二阶段,氢气组与安慰剂组干预后所有测试结果的差异趋势同试验的第一阶段。整合后试验结果显示仍然是氢气组上述指标检测值优于安慰剂组(P <0.05)。(2)线性回归分析显示,干预后疲劳目测类比评分和被动位置觉结果呈正相关(r=0.327,P=0.023),即高强度运动后主观疲劳程度越高被动位置觉结果越差。(3)结果表明,高强度运动前吸入富氢气体能够降低运动后的疲劳程度,从而改善本体感觉和肌肉耐力表现,这可能是降低损伤发生的一个新策略,并且富氢气体有效性是可以重复实现的。BACKGROUND:Hydrogen,as an antioxidant,can reduce oxidative stress induced by strenuous exercise and achieve the effect of improving fatigue.Several studies have been reported on the potential effects of hydrogen-rich water or hydrogen-rich gas on improving exercise fatigue and athletic performance.OBJECTIVE:To investigate the effects of hydrogen-rich gas inhalation prior to high-intensity exercise on proprioception and muscular endurance performance after exercise fatigue.METHODS:Through a randomized,double-blind,crossover,and repeated measurement experimental design,24 healthy men were randomly divided into group A and group B,with 12 in each group.In the first phase of the crossover experiment,group A inhaled hydrogen-rich gas(hydrogen group)for 20 minutes and group B inhaled placebo gas(air;placebo group)for 20 minutes.Then,cycle ergometers were used to establish the fatigue model.Visual analog fatigue scale,heart rate variability,knee joint proprioception(passive position perception,joint motion perception,and muscle force perception)and isometric knee extension muscle endurance were tested before and after intervention.After a 7-day washout period,two groups exchanged intervention methods and the above tests were performed again in the second phase of the experiment.Differences between the results of groups A and B in the two phases were compared,and finally the results of the two phases were integrated to compare the overall differences between hydrogen intervention and placebo intervention.RESULTS AND CONCLUSION:In the first phase of the crossover experiment,the visual analog fatigue scale score of the hydrogen group after intervention was significantly lower than that of the placebo group(P<0.01).The root mean square of the difference between the adjacent R-R,mean low-frequency output power,mean high-frequency output power,and isometric muscle endurance after intervention in the hydrogen group were significantly higher than those in the placebo group(P<0.05).Passive position perception and joint motion pe
