Peak flow was measured by radioactive xenon in fifteen normal subjects in the anterior tibial muscle after maximal ischaemic exercise. The postischaemic exercise peak flow was 75 +/- 13 ml/100 g muscle/min (mean +/- SD), when the test was performed while the subjects rested in the horizontal position. When the same test was performed with the subjects resting in a 45 degrees feet down tilted position, the peak flow increased very much, about 65%, and averaged 125 +/- 17 ml/100 g muscle/min. The increased peak flow in the feet tilted position is explained by passive dilatation of the vessels due to increased hydrostatic pressure. It is suggested, that measurement of maximal ischaemic exercise blood flow in the tilted position may be a more sensitive procedure for detection of minimal vascular changes due to the very high blood flow obtained.
在15名正常受试者的胫前肌进行最大缺血运动后，用放射性氙测量峰值血流。当受试者处于水平位休息时进行测试，缺血运动后的峰值血流为75±13毫升/100克肌肉/分钟（平均值±标准差）。当受试者处于双脚向下倾斜45度的休息位进行相同测试时，峰值血流大幅增加，约65%，平均为125±17毫升/100克肌肉/分钟。双脚倾斜位峰值血流增加的原因是静水压力增加导致血管被动扩张。有人认为，在倾斜位测量最大缺血运动血流可能是检测微小血管变化的更敏感方法，因为能获得非常高的血流。
