Accumulated Exercise
Physical activity guidelines endorse the accumulation of exercise in short bouts over the course of the day to make it easier for individuals to meet daily recommendations[28]. In a quasi-systematic review, Murphy and colleagues reviewed the studies that have compared the effects of a single continuous bout of exercise versus the effects of short accumulated bouts of the same total duration and identified six studies that have reported BP measures pre- and post-intervention[65]. Two of the six studies showed significant decreases in BP following training, with similar reductions reported among continuous and accumulated exercise bouts. Authors concluded that there is insufficient data in the present literature to allow comparison of the effects of accumulated and continuous bouts of exercise on BP. Furthermore, none of the identified studies excluded hypertensives, thus data supporting physical activity guidelines that endorse the accumulation of exercise in 10-minute bouts or greater for the prevention of hypertension are scarce and still needed.
