    Abstract:
    This is a report about the therapeutic behavior of blood pressure and heart rate in patients suffering from hypertension. Forty male patients with hypertension (age: 30-53 years) were treated either with running or swimming therapy according to the stamina principle or with nifedipine therapy (40-60 mg/d). Both groups were randomized. Peripheric hemodynamics were investigated by means of the Xenon-133-muscle-clearance (M. tibialis anterior). The values of interest were half-value time (T1/2) and the mean functional vessel diameter. Additionally total peripheric vascular resistance (TPR) and radiocardiographic cardiac output (CO) were measured. Significant decrease of systolic and diastolic blood pressure values at rest were obtained with the therapeutic regimens. CO increased and the TPR decreased. The decrease of blood pressure during physical therapy and with nifedipine therapy also is due to the enhanced microcirculation. Half-value time of muscle clearance (T1/2) and the mean functional vascular diameter were increased significantly.
