We studied the relationship between the physical exercise capacity and the orthostatic tolerance of physically average fit and very fit dayworkers at different times of the day. Six male railroad workers were physically very fit and six were averagely fit (mean of the maximal oxygen consumption 57.4 and 34.6 ml.kg-1.min-1, respectively. The mean age was 32 years. The orthostatic tests were performed with a tilt-table at 2.00, 6.00, 10.00, 14.00, 18.00, and 22.00 hours on six different days. Orthostatic lability at night was seen in both groups. At 14.00 and 18.00 hours the orthostatic tolerance in average fit men was slightly lower than in very fit men. This difference in the orthostatic tolerance between the groups may be a sign of the interdependence of good exercise tolerance and orthostatic tolerance.
我们研究了身体状况一般良好和非常良好的日班工人在一天中不同时间的体育锻炼能力与直立耐力之间的关系。六名男性铁路工人身体状况非常良好，六名身体状况一般良好（最大耗氧量平均值分别为57.4和34.6毫升·千克⁻¹·分钟⁻¹）。平均年龄为32岁。在六个不同的日子里，于2.00、6.00、10.00、14.00、18.00和22.00时使用倾斜台进行直立试验。两组在夜间均出现直立不耐受。在14.00和18.00时，身体状况一般良好的男性的直立耐力略低于身体状况非常良好的男性。两组之间直立耐力的这种差异可能是良好运动耐力与直立耐力相互依存的一个标志。
