Objective To observe and compare the effects of exercise on the cardiac function during 30 d head-down tilt bed rest, and to see if these protocols would positively affect cardiac function. Methods Fifteen healthy male volunteers were randomly divided into control group, lower limb muscular exercise group and bicycle ergometric exercise group, with 5 in each group.

目的 本实验利用头低位卧床模拟失重，通过观察和比较30 d卧床期间不同体育锻炼方式对心脏收缩泵血功能的影响，旨在进一步明确体育锻炼对失重后心脏功能变化的对抗效果，为制定我国载人航天时航天员失重对抗方案提供实验依据。

Effects of exercise on limb muscle during 30 d head-down tilt bed rest We observed and compared the effects of lower limb muscular exercise with bicycle ergometric exercise during 30 d HDT bed rest on the changes of perimeter of leg, cross-sectional area of leg and mean amplitude of calf.

30 d头低位卧床期间体育锻炼对下肢肌肉的影响本实验进行了30 d头低位卧床，观察和比较了卧床期间下肢肌力训练和自行车功量计训练对小腿围径、小腿截面积和腓肠肌肌电平均振幅的影响。

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。

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。

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。

The purpose of this study was to examine the effcet of acute exercise and acute exercise after hyperthermic treatment on hsp70 and oxidative stress markers SOD and MDA At the same time, we investigated hsp70 response changes to exercise.

通过观察急性运动和热预处理后急性运动对大鼠股四头肌热休克蛋白70表达影响的时相性变化和氧化应激标志物超氧化物歧化酶活性和丙二醛含量的变化，探讨HSP70对急性运动大鼠股四头肌抗氧化能力的影响和股四头肌HSP70表达的应答性反应。

Aerobic exercise facilitates the growth of development stage skeletal muscles, and may cause a transformation of white fibers to intermedial fibers. The size of skeletal muscles is associated with the exercise styles and exercise levels and also the development stage.

有氧运动对发育期大鼠骨骼肌各型肌纤维有明显的促增长作用，并可引起白肌纤维向中间肌纤维的转变，肌纤维的形态结构不仅同运动方式及运动负荷有关，同时还与发育的年龄有着密切的相关。

On the basis of these treatments, the patients in the treatment group also had aerobic kinesitherapy through limb and trunk exercises with assistance to improve oxygen consumption of the body and increase the heart rate. In each session of exercise, the patients were supposed to attain the target heart rate of 70％ to 85％ of the personal highest safe heart rate.At the beginning, each session of exercise lasted for 10-15 minutes and the heart rate or pulse was measured every 4-6 minutes, with the patients'heart rate allowed to increase by no more than 20/minute and the patients not feeling tired. The subsequent exercise time gradually increased but not over 30-40 minutes, twice a day for no less than 5 days a week.

干预：两组患者均给予改善循环和营养神经药物等治疗，在此基础上，治疗组采用有氧运动疗法：以靶心率为指标，即以通过运动获得的个人最高安全心率70％～85％作为每次运动的靶心率，开始时每次运动10～15 min，每运动4～6 min测一次心率或脉搏，运动以患者心率增加不超过20次/min、患者感觉不疲乏为度，以后逐渐增加运动时间，直至每次活动持续时间30-40 min，2次/d，每周治疗不少于5 d。
