Rises in the directly measured arterial pressure were produced by intravenous injections of phenylephrine, and systolic pressure was correlated with the following pulse interval. The slope of the systolic pressure-pulse interval relation was used to express reflex sensitivity. With increasing exercise, the reflex sensitivity decreased progressively so that at a level of exercise which produced a heart rate of 150/min there was no reflex cardiac slowing in response to a provoked rise of pressure. The reduction in reflex sensitivity was studied during the changes from rest to exercise and vice versa. Reflex sensitivity decreased within 5 seconds of the onset of exercise.
