Immediate impact of exercise on arterial stiffness in humans

Abstract

Background and objectives: Increased arterial stiff- ness is an accepted cardiovascular risk factor. Several studies have shown that regular exercise is associated with reduced arterial stiffness. However, the acute effect is not well known. The aim of this study was to evaluate the immediate impact of exercise on arterial stiffness measured by pulse wave velocity (PWV). Subjects and Methods: Data from 100 consecutive patients who underwent graded maximal aerobic ex- ercise test and pulse wave velocity study due to chest pain were analyzed. Results: With respect to bra- chial-ankle pulse wave velocity (baPWV), it decreased after the exercise test (before vs. after; 1420 ± 260 vs 1358 ± 245, 1428 ± 255, vs 1360 ± 239 cm/sec; left and right, respectively). Upper extremity systolic blood pressure did not change from baseline. However, up- per extremity diastolic blood pressure increased sli- ghtly. In addition, lower extremity blood pressure de- creased in both systolic and diastolic phases. In both normotensives and hypertensives, baPWV decreased after exercise test. Conclusion: Exercise immediately decreases arterial stiffness. Keywords:
