【摘要】 ６名年龄３５±６岁男性受试者作为对照组，６名年龄３６±６岁练气功的男性受试者为练气功组。实验程序包括２ｄ的准备期，７ｄ的头低位－６°卧床（ＨＤＢＲ－６°）期和２ｄ的恢复期。每天收集２４ｈ全尿，测定尿皮质醇（ＵＣＯＲ）和尿醛固酮（ＵＡＬＤ）；每两天采集耳血一次，测定超氧化物歧化酶（ＳＯＤ）的活性。结果表明：卧床前两组间ＵＣＯＲ和ＳＯＤ没有显著差异，而ＨＤＢＲ－６°后对照组ＵＣＯＲ和ＳＯＤ明显增加（Ｐ＜０．０１），练功组仅有增加的趋势，对照组和练功组相比在ＨＤＢＲ－６°期间差别显著（ｐ＜０．０１）。这表明练气功组比对照组有较好的耐受ＨＤＢＲ－６°的应激能力，对保持机体内环境稳定具有重要的意义。更多还原

【Abstract】 Six healthy male volunteers aged 35±6 yrs were selected as controlgroup and six male volunteers aged 36±6 yrs as Qigong group。 The schedule of experi-ments included a 2-day control period pre-HDBR-6°),a 7-day head down-6° bedrest(HDBR-6°) period and a 2-day recovery period(post-HDBR-6°)。 Urine sampleswere collected in 24h。 Ear blood was collected once every two days。 Urinary cortisol(U-COR) ,aldosterone(UALD ) and superoxide dismutase(SOD ) activity in blood weremeasured respectively。 The results indicated that the pre-HDBR contents of UCOR andSOD had no significant difference between the two groups , but the post-HDBR the con-tents of UCOR and SOD were higher in the control group(P<0.01) , and the contentsof UCOR and SOD showed a tendency of increase in the Qigong group。There were verysignificant differences(P<0.01 ) between control and Qigong group during HDBR-6°。 These findings indicate that the subjects exercising Qigong were more tolerable tothe stress of HDBR-6°than the control group。Qigong is important in maintaining sta-bility of internal environment of the organism。更多还原
