Abstract:
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.

Hypertension and Regulation of Blood Pressure
Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the diastolic...
