Systemic arterial blood pressure responses of stroke-prone spontaneously hypertensive rats to treadmill exercise

The present study was undertaken to compare the systemic blood pressure responses during graded acute exercise of stroke-prone spontaneously hypertensive rats (SHRSP) and normotensive Wistar-Kyoto rats (WKY). Systemic blood pressure was measured by left carotid artery catheter during exercise. Systolic blood pressure incre-ments with running exercises at 10, 15, and 20 m/min were significantly greater in SHRSP than in WKY. Diastolic blood pressure increments with exercise were singnificantly greater only at 20 m/min in SHRSP compared to WKY. This study suggests that the blood pressure response to exercise is accentuated in SHRSP.
