低氧,气功对抗卧床模拟失重和卧床后立位耐力的观察

为研究低氧、气功对抗卧床模拟失重的效果，１５名１９－２２岁的健康男性青年。分为三组：对照组，低氧组，气功组。结果表明：卧床期间，被试乾的生理功能都有不同程度的降低。气功组的小腿周径的减小，体重、脉压、日均心输出量和基础每搏量的降低均显著小于对照组（Ｐ〈０．０５）。低氧组的小腿周径和基础每搏量的降低经对照组显著减少（Ｐ〈０．０５），体重、脉压和日均心输出量的降低均小于对照组，但无显著性（Ｐ〉０．０５

A Study on the Counteracting Effect of Hypoxia and Qigong on Simulated Weightlessness and Orthostatic Tolerance after Bedrest.

-6 degrees head down bed rest (-6 degrees HDBR) 21d were used to simulate weightlessness. 15 healthy males, aged 19-22, were divided into 3 groups with 5 people in each group: control group (-6 degrees HDBR), hypoxia group (-6 degrees HDBR + Low Oxygen), Qigong group (-6 degrees HDBR + Qigong). The results showed that the reduction of weight, perimeter of shank, daily average cardic output, basal cardic output and the pulse pressure of the Qigong group were lower than those of the control group (P<0.05). The basal cardic output and the perimeter of shank of the Hypoxia group reduced significantly than those of the control group (P<0.05). However, the reduction of the other physiological functions of the Hypoxia group were not significantly lower than that of the control group (P>0.05). During HUT +75 degrees 20 min orthostatic tolerance test after HDBR, the parameters in the Hypoxia group were better than those in the other groups. The average standing time was also longer, and no presyncopal symptom occured.
