In our country, the population of old age is grown up in soon late decay. Twenty million populous are counted as year over seventy five in now. In the peoples one million and two hundred thousands peoples will need all time lest in bed. The bed lest make peoples to free from adaptation by standing living style and make delay from recovery from situation of ill moreover make delay to back to the life in social. So the purpose of these experiments is determination of 1) body away, 2) simple reaction time, and selective reaction time and 3) performance before and after 1 day and after 2 day by 14 days 6 degree head-down-bed-rest in 13 male subjects. Furthermore the purpose of these experiments is determination of 4) effects of physical exercise at the level of 60 w and 2G centrifuge for 30 min on ten days (1,2,3,5,7,9,11,12,13,14) during 14 days 6 degree head-down-bed-rest. Physiological conditioning and reconditioning in body cooperative physical control function by 14 days 6 degree head … More -down-bed-rest. Subjects are healthy 13 students (age 20±2 years old, height 173±3 cm, weight 67±11 kg)(Mean ± Standard Deviation). The subjects measured body sway by using three stress measure amplifiers (Kyowa DPM711B) and A/D converter (ADI, Mac Lab/8s) before and after 1 day and after 2 day 14 days 6 degree head-down-bed-rest at standing position with open eye during three minutes. Statistics methods are used with ANOVA and Dunett analysis. However complete measurements were done at pre control 100%, nein subjects in 13 subjects were completely measured duration 3 minutes measurement's time at 1 day after 14 days 6 degree head-down-bed-rest. At 2 day after 14 days 6 degree head-down-bed-rest all subjects were completed in body sway measurement at standing position. Significant increase was measured after 1 day in trace length of center of gravity per 1 minute in comparison of pre control. These results suggest that long time bed lest is bad in healthy young man. On 1 day after long bed-rest subjects must be cared to fall down. Reaction times were not short significantly before 8 day of bed-rest in comparison pre control. The subjects did not pain after the 8 day of bed-rest in questionnaire results. Performance results were increased significantly at 13 day and after 2 day in comparison pre control. These data were shown last effects. Physical exercise and 2G centrifuge were not significant effects on body sway. But 14-day 6 degree head-down-bed-rest effects significantly longer after 1 day in trace length of center of gravity per 1 minute in comparison of pre control. Less

在我国，老年人口是在不久的将来长大的。现在人口超过七十五岁的有二千万。在人民中，有一百万到二十万人将需要所有的时间，以免在床上。床使人们从站立的生活方式的适应中解脱出来，使人们从疾病的状态中恢复迟缓，使人们在社会生活中恢复迟缓。因此，本实验的目的是测定13名男性受试者14天6度头卧休息前后1天和2天的表现：1)身体距离，2)简单反应时间，3)选择性反应时间。此外，这些实验的目的是确定4)在60 w和2G水平下进行30分钟的体育锻炼，在14天（1、2、3、5、7、9、11、12、13、14），6度头下床休息。经14天6度头后身体协同生理控制功能的生理调理与修复。研究对象为健康学生13名（年龄20±2岁，身高173±3cm，体重67±11kg）（均数±标准差）。受试者于1天、2天后、14天6度头下床站立、睁眼休息3分钟，分别用3台应力测量放大器（Kyowa DPM711B）和A/D转换器（ADI, Mac Lab/8s）测量身体摇摆。统计方法采用方差分析和Dunett分析。然而，在控制前100%完成了完整的测量，13名受试者中没有1名受试者在14天6度头下床休息后的第1天完成了3分钟的测量时间。在6度头下床休息14天后的第2天，所有受试者完成站立姿势的身体摇摆测量。与对照组相比，1 d后每1分钟重心的迹线长度显著增加。这些结果表明，长时间卧床对健康的年轻人不利。在长时间卧床休息后的第1天，受试者必须小心摔倒。与对照组相比，卧床前8天的反应时间不明显缩短。问卷调查结果显示，卧床8天后受试者无疼痛感。13 d和2 d后的生产性能显著提高。这些数据显示了最后的效果。体育锻炼和2G离心机对身体摇摆无显著影响。但与对照组相比，14 d 6度头下床休息后1 d的每1分钟重心轨迹长度显著延长。少
