目的探讨新的对抗失重措施。方法１５名、年龄１９～２２岁的健康男性青年为被试者。头低位－６°卧床（－６°ＨＤＢＲ）模拟失重，持续２１ｄ。实验分对照组（单纯卧床）、低氧组（卧床＋低氧）和气功组（卧床＋气功）。低氧组卧床期间每人每天吸两次低氧，每次２０ｍｉｎ。气功组卧床中每天练功三次，每次４５ｍｉｎ。三组卧床前、后进行２０ｍｉｎ＋７５°的立位实验。结果三组被试者在卧床前立位中的心电图未发生明显变化，心律正常。卧床２１ｄ后立位实验中对照组２人出现房性和窦性心律紊乱；气功组２人出现结性心律紊乱。低氧组所有人均未发生心律紊乱。结论低氧对抗卧床后立位耐立降低效果较好。
Objective To explore new measures against weight loss. Method 15 healthy young men aged 19 to 22 years as subjects. Head-low -6 ° bed (-6 ° HDBR) simulated weightlessness, sustained 21d. The experiment was divided into control group (bed alone), hypoxia group (bed + hypoxia) and qigong group (bed + qigong). Hypoxia group bed per person per day twice a day inhaled hypoxia, each 20min. Qigong group bed practicing three times a day, each 45min. Three sets of bed before and after 20min +75 ° vertical position experiment. Results The three groups of subjects in the pre-bed position in the ECG did not change significantly, the rhythm of normal. Two days after bedridden position control, two patients in the control group had atrial and sinus rhythm disturbances; two patients in the Qigong group had a node rhythm disorder. Hypoxia group, no one had arrhythmia. Conclusion Hypoxia has a good effect of reducing standing stand-up after bed rest.
