We have previously reported that blood pressure during running shows a peculiar pattern attributable to the beat phenomenon. To elucidate the mechanism behind this phenomenon in 10 amateur athletes, intra-arterial blood pressure was continuously recorded using the Oxford technique. During the run, each athlete carried on his chest a container filled with saline kept under pressure, connected to a second transducer. In the container, pressure waves ranging in amplitude from +/- 10 to +/- 62 mmHg were recorded. Their frequency was equal to that of the athletes' strides. When these waves were added by computer to the blood pressure tracing recorded during a bicycle ergometric test, the resultant harmonic proved to be similar to the tracing observed during running. The present results demonstrate that the running-induced blood pressure pattern is the sum of the accessory wave generated by the rhythmic aortic shocks produced by running locomotion and the normal sphygmic wave.
我们之前曾报道，跑步过程中的血压呈现出一种特殊模式，这归因于搏动现象。为了阐明10名业余运动员出现这种现象的机制，我们采用牛津技术持续记录动脉内血压。跑步过程中，每位运动员在胸前携带一个装有生理盐水的容器，该容器保持压力，并连接到第二个传感器。在容器中，记录到幅度在±10至±62 mmHg之间的压力波。其频率与运动员的步幅频率相等。当通过计算机将这些波添加到自行车测力计测试期间记录的血压描记图上时，得到的谐波被证明与跑步期间观察到的描记图相似。目前的结果表明，跑步引起的血压模式是由跑步运动产生的有节奏的主动脉冲击所产生的辅助波与正常脉搏波的总和。
