Arterial compliance, systolic pressure and heart rate in elderly women at rest and on exercise.
In two groups of elderly women, the relationships between arterial compliance estimated by pulse wave velocity (PWV), and systolic blood pressure (SP), heart rate (HR), oxygen consumption and the time taken to run 400 m have been studies. Both at rest and with increasing levels of exercise, faster PWVs are associated with higher SPs. These is a tendency for resting HR to be higher with faster PWVs. The changes in HR and oxygen consumption from resting values are strikingly increased with faster PWVs. The time taken over 400 m rises as arterial compliance falls. Therefore, it seems that, with aging, reduced arterial compliance is a major factor affecting cardiovascular responses to exercise.
