Suboptimal blood pressure, defined as >115/75 mmHg by meta-analysis, exhibits a positive relationship with cardiovascular disease, and is the leading attributable risk factor for death. Research has illustrated that even blood pressure (BP) below the hypertensive levels can contribute to increased vascular mortality. It has been demonstrated that for incremental increases in blood pressure (every 20 mmHg systolic or 10 mmHg diastolic) there is a twofold increase in cardiovascular disease risk. However, mounting evidence suggests that increased fitness and physical activity4 may attenuate the typical age related increase in BP to hypertensive levels. Exercise has been recommended as the first line of treatment in prehypertension and suboptimal BP, and a single bout of exercise (as short at 10 min) has been shown to lower BP for up to 12 hours post. It is this extended bout of postexercise hypotension (PEH) that is thought to contribute to the anti-hypertensive effects of exercise.
