【摘要】：目的观察在 2 1d头低位卧床的第一周和最后一周进行下体负压锻炼对立位耐力和心功能的影响。方法 1 2名健康男性志愿者 ,随机分为对照组和LBNP组 ,每组 6人 ,均参加 - 6°头低位倾斜卧床实验。对照组在卧床期间不做任何处理 ,LBNP组在卧床第一周和最后一周 ,每天进行 1h、- 30mmHg的下体负压锻炼。卧床前和卧床第 1 0、2 1天在倾斜床上进行 3次立位耐力检查 ,卧床期间测量心脏泵血和收缩功能等指标。结果卧床前两组 1 2名被试者均顺利通过立位耐力检查。卧床第 1 0和 2 1天 ,对照组所有被试者均不能通过立位耐力检查 ,而下体负压组仅有 1人未通过 ,卧床第 2 1天下
[Abstract]:Objective to observe the effects of lower body negative pressure exercise on position endurance and cardiac function during the first and last week of head down bed rest for 21 days. Methods Twelve healthy male volunteers were randomly divided into control group and LBNP group with 6 in each group. The control group did not do any treatment during the bed-rest period, and the LBNP group was in the first and last week of bed rest. 1h-30mmHg negative body pressure exercise was performed every day. Three standing endurance tests were performed before bed rest and 10 ~ (th) day after bed rest on the tilted bed. Results 12 subjects in the first two groups passed the orthostatic endurance test successfully. On the 10th and 21st days of bed rest, the indexes of cardiac pump blood and systolic function were measured. All subjects in the control group were unable to pass the standing endurance test, while only one person in the lower body negative pressure group failed, lying in bed for the 21st day.
