Three or four short, brisk walks throughout the day may be more helpful to people watching their blood pressure than one continuous bout of exercise, Indiana University researchers report.
The study comprised 15 men and 5 women with pre-hypertension. Findings showed that both forms of exercise, accumulated and continuous, decreased study participants’ blood pressure by the same amount. The effect lasted for around 11 hours in the group who took four 10-minute walks, compared to 7 hours for the group who walked continuously for 40 minutes.
“We had no idea the short bouts would be better,” comments study chief Janet P. Wallace. “Most studies found in the literature report the long, continuous session as more effective for many variables.”
