【摘要】：目的:探讨富氢水对女子柔道运动员机体抗氧化能力的影响。方法:16名女子柔道运动员随机分为实验组和对照组,进行为期4周的实验,实验组每天上午和下午训练前或训练中各补充2袋富氢水(200 ml/袋),对照组则补充矿泉水。为不影响运动员的训练,不限制运动员的其他饮水。同时选择第14天上午的技术对抗训练课作为大强度训练课,运动员在训练前和训练中各补充2袋富氢水。在实验第1天、14天、28天清晨及第14天上午大强度训练课后1 h分别取静脉血5 ml用于抗氧化能力相关指标的检测。结果:在大负荷技术训练后1小时,对照组血中超氧化物歧化酶(SOD)、总抗氧化能力显著低于训练前(P0.05),而丙二醛(MDA)则显著高于训练前水平(P0.05),CAT活力和GSH-PX活力无显著变化。实验组与训练前比较,各项指标均无显著变化;与对照组比较,SOD和总抗氧化能力显著增加(P0.05),而MDA则出现显著降低(P0.05)。4周训练中,第1天、第14天和第28天清晨血中两组各指标均未见显著变化(P0.05)。结论:补充富氢水能显著降低女子柔道运动员大强度训练后导致的自由基水平升高,提高抗氧化酶活性,增强总抗氧化能力,对于大负荷训练导致的机体脂质过氧化具有保护作用。
[Abstract]:Objective: to investigate the effect of hydrogen rich water on the antioxidant capacity of women judo athletes. Methods: one hundred and sixteen women judo athletes were randomly divided into experimental group and control group for 4 weeks. The experimental group was supplemented with 2 bags of hydrogen rich water (200 ml / bag) before and during training every morning and afternoon, while the control group was supplemented with mineral water, which did not affect the training of athletes. There is no restriction on other drinking water for athletes. At the same time, the technical confrontation training class of the 14th morning is chosen as the high-intensity training class. The athletes supplement 2 bags of hydrogen rich water before and during training. On the first day of the experiment, 14 days. In the morning of 28 days and 14 days in the morning, 5 ml venous blood was taken for the determination of antioxidant capacity at 1 hour after intensive training. Results: 1 hour after heavy load training. In the control group, the total antioxidant capacity of SOD was significantly lower than that of P0.05G before training, while the MDAs of malondialdehyde (MDA) was significantly higher than that of P0.05 before training. There was no significant change in CAT activity and GSH-PX activity. Compared with the control group, sod and total antioxidant capacity increased significantly, while MDA decreased significantly during the 1st day of P0.054-week training. On the 14th day and the 28th day, no significant changes were found in the blood indexes of the two groups. Conclusion: supplement of hydrogen rich water can significantly reduce the increase of free radical level of female judo athletes after intensive training. Increasing the activity of antioxidant enzymes and enhancing the total antioxidant ability can protect the body from lipid peroxidation caused by heavy load training.

【正文快照】： 急性运动和力竭运动都可以导致内源性自由基增多,脂质过氧化反应增强,构成对细胞膜系统的损害[1]。自由基和脂质过氧化损伤与运动性疲劳的发生密切相关。目前比较一致的观点认为氢气具有选择性抗氧化作用,对于对生物体有害的自由基,氢气能主动性选择与其结合生成水[2]。富氢水
