摘要
以头低位（－６°）卧床模拟失重，共２１ｄ。５名男性经过９５ｄ气功训练的分比为气功组，另外５名男性为对照组。年龄为１９～２１岁。卧床期间，气功组每天进行３次气功训练，每次约５０ｍｉｎ。在卧床前中后期测量心输出量、心率、心电、血压、体重、小腿周径、脉图、神经传导速度、血中的ＳＯＤ、Ｃａ￣（２＋）和立位耐力、中医综合检查。结果表明，和对照组相比，卧床中气功组体重和小腿周径下降得少、主观感觉和客观体征明显轻、心输出量减少得少、脉压差明显高。神经传导速度明显快、体内超氧化物产生少、钙丢失较慢，说明气功锻炼使气功组对模拟失重的对抗能力明显高于对照组。
Weightlessness is simulated with-6°head down bedrest(HDBR-6°).10 healthy male subjects aged 19～21 years were served as subjects.5 men undergone Qigong training were classified as Qigong group.The other 5 men without Qigong training served as the control.They all underwent HDBR- 6 °for 21d.Qigong training are performed 3 times a day 50min a time in Qigong group.Cardiac output(CO)、heart rate(HR)、electrocardiogram(ECG)、body weight(BW)、circumference of leg、pulse graph、H reflex、concentration of SOD、Ca￣(++)in blood、tolerance to orthostatic tilt were measured and Chinese medical exami-nation was made,The results indicated that BW and circumference of leg in Qigong group decreased less as compared with the control.Subjective sensation and objective symptoms were less severe and CO decreased less as compared with the control.The total peripheral re-sistance of cardiovascular system decreased and the pulse pressure increased as compared with control group.The nervous transmission speed was higher and concentration of SOD and Ca￣(++)in blood was lower than that of the control group.It showed that Qigong practice in-creased the tolerance to simulated weightlessness in young men.
