Effects of 14 days 6 degree head-down-bed-rest on cooperative exercise control function

在我国，老年人口正在迅速增长.两千万人口在现在超过七十五岁的时候被统计出来。在人民中，一百二十万人将需要所有的时间，除非在床上。该床避免使人们脱离长期生活方式的适应，延缓病情的恢复，进而延缓社会生活的恢复。因此，本实验的目的是测定13名男性受试者头低位卧床14天前后的1）身体离开、2）简单反应时、选择反应时和3）成绩。本实验还研究了在14天6度头低位卧床休息期间，进行为期10天（1、2、3、5、7、9、11、12、13、14）的60 W、2G离心机30 min运动的效果。14天6度头的生理调节和身体协调物理控制功能的再调节 ...更多信息 - 卧床休息受试者为健康的13名学生（年龄20±2岁，身高173±3 cm，体重67±11 kg）（平均值±标准差）。受试者在头低位6 °卧床站立位睁眼3分钟前后，分别用三个应力测量放大器（Kyowa DPM 711 B）和A/D转换器（ADI，Mac Lab/8 s）测量身体摇摆。统计方法采用方差分析和Dunett分析。对照前100%完成测量，头低位卧床14天后第1天，13名受试者中无1人完成测量，测量时间为3 min。在14天后的第2天，所有受试者头低位卧床6度，完成站立位身体摇摆测量。与对照前相比，1天后测量到每1分钟重心轨迹长度显著增加。结果提示，健康青年长期卧床对健康危害较大，长期卧床后1天内发生跌倒时，应给予护理。卧床前8天反应时与对照前比较无显著性差异。问卷调查结果显示，受试者卧床休息8天后无疼痛。与对照前相比，13天和2天后的性能结果显著增加。这些数据显示了最终效应。体育锻炼和2G离心机对身体摇摆的影响不显著。但头低位卧床14天后，6度头低位卧床1天后，每分钟重心轨迹长度与对照前相比显著延长。少

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
