30 d头低位卧床期间体育锻炼对脑血流的影响本实验利用经颅多普勒超声技术观察了30 d -6°HDT卧床期间下肢肌力训练和自行车功量计训练对脑血流的影响。

The results showed that in the HDT 30th day, the orthostatic tolerance decreased significantly (P.01) in control group compared with pre-HDT, but in the limb muscular group and bicycle ergometric group, the orthostatic tolerance decreased insignificantly compared with pre-HDT.

结果发现：卧床第30 d，对照组的立位耐力较卧床前显著降低(P.01)，而下肢肌力训练组和自行车功量计训练组的立位耐力较卧床前有所降低，但未达到显著水平。

Effects of exercise on heart function during 30d head-down tilt bed rest We observed and compared effects of lower limb muscular exercise with bicycle ergometric exercise during 30 d HDT bed rest on the changes of heart systole function and heart pump function.

30 d头低位卧床期间体育锻炼对心脏功能的影响本实验通过观察和比较30 d -6°HDT卧床期间下肢肌力训练或自行车功量计训练对心脏收缩泵血功能的影响。

The limb muscular exercise and the bicycle ergometric exercise in some extent can ameliorated the muscle atrophy following simulated microgravity, and played a role in restoring muscle structure and function.

下肢肌力训练和自行车功量计训练对防止模拟失重所致肌肉萎缩，促进肌肉恢复有一定的作用。

These results suggested that 30 d HDT bed rest has induced significant reduction in heart systole function and heart pump function. The limb muscular exercise and the bicycle ergometric exercise to some extent can improve the heart systole function; however, the bicycle ergometric exercise was better.

结果提示，30 d头低位卧床可引起心脏收缩泵血功能下降，下肢肌力训练和自行车功量计训练可在一定程度上改善心脏收缩功能，其中自行车功量计训练的对抗效果更佳。

Effects of exercise on orthostatic tolerance, exercise capacity and heart rate variability during 30 d HDT bed rest We observed and compared effects of lower limb muscular exercise with bicycle ergometric exercise during 30 d HDT bed rest on the changes of orthostatic tolerance, maximal exercise time, body weight and heart rate variability.

d头低位卧床期间体育锻炼对立位耐力、运动耐力和心率变异性的影响本实验观察和比较了30 d -6°头低位卧床期间下肢肌力训练和自行车功量计训练对立位耐力、最大运动时间、体重以及心率变异性的影响。

The cardiac systole and pump functions decrease significantly during 30 d HDT bed rest. The limb muscular exercise and the bicycle ergometric exercise may improve the cardiovascular system to some extent. Further, the bicycle ergometric exercise is the better one.

30 d头低位卧床可引起心脏收缩泵血功能下降，下肢肌力训练和自行车功率计训练可在一定程度上改善心血管功能，其中自行车功率计训练的对抗效果更佳。

Compared with pre-HDT, the MA of calf decreased significantly (P.05) in the HDT 1st and 22nd day in control group; the MA of calf decreased significantly (P.05) in the HDT 7th, 22nd 26th, 30th day in limb muscular group; the MA of calf decreased significantly (P.05) in the HDT 7th, 10th, 22nd and 30th day in bicycle ergometric group.
