Beats modulate blood pressure during running.
Blood pressure (BP) changes during running were studied in 25 subjects with intraarterial monitoring. Periodic pulse pressure variations ranging from 20 to 200 mm Hg were recorded throughout the exercise. To prove that these pressure oscillations were due to a "beat" phenomenon 10 athletes ran with a Teruflex container filled with saline: pressure changes up to +/- 62 mm Hg were recorded in the container. These pressure waves were added by computer to the sphygmic waves recorded intraarterially in the same subject during bicycle ergometry: the resultant tracing showed a beat-shaped pattern similar to that recorded during running.
