Abstract:
Interrelations between physical exercise, monoamines and hypertension are postulated by various investigators. The purpose of the present study was to determine and compare catecholamine levels at rest and after a 12-week aerobic exercise program in 11 sedentary normotensive (N) and 8 hypertensive (H) men. Plasma catecholamines were determined by high performance liquid chromatography with electrochemical detection. A significant post-exercise increase in plasma noradrenaline was observed in the N and H groups (P < 0.01) both before and after the aerobic exercise program. The hypertensive group showed a significant reduction of the sum of 7 skinfold thickness scores after the aerobic exercise program (from 178.7 +/- 65.6 to 144.0 +/- 47.4 mm) although no significant difference was observed when the body mass index was compared. A significant reduction in diastolic blood pressure at rest was observed in the H group after the aerobic exercise program (from 99.2 +/- 2.0 to 85.0 +/- 5.5). There were no significant differences in catecholamine concentrations between groups before and after the 12-week aerobic exercise program at rest and post-exercise. These data show a relationship between physical exercise and hypertension that was not related to changes in plasma catecholamine levels.

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...

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...
