Changes in the mineral content of the left heel bone of the Salyut-6 crewmembers who made 75--184-day flights were measured by direct photon absorptiometry. The postflight results were compared with the predicted rate of bone atrophy. This parameter was derived from the data concerning variations in the mineral content of spongy bones of men and animals exposed to actual and simulated weightlessness for various time intervals. The efficiency of countermeasures against the adverse effect of weightlessness on bones was assessed. It is concluded that crewmembers with a high content of minerals in spongy structures of the axial skeleton and a low basal metabolism should be selected for prolonged space missions.
通过直接光子吸收法测量了执行75至184天飞行任务的“礼炮6号”机组人员左脚跟骨矿物质含量的变化。将飞行后的结果与预测的骨质萎缩率进行了比较。该参数是根据有关在不同时间间隔内处于实际和模拟失重状态的人和动物松质骨矿物质含量变化的数据得出的。评估了对抗失重对骨骼不利影响的对策的效果。得出的结论是，对于长期太空任务，应选择轴向骨骼松质结构中矿物质含量高且基础代谢低的机组人员。
