Complementary and Alternative Medicine: Fair, Balanced, and to the Point
  • About this web log

    This blog is intended as an objective and dispassionate source of information on the latest CAM research. Since my background is in pharmacy and allopathic medicine, I view all CAM as advancing through the development pipeline to eventually become integrated into mainstream medical practice. Some will succeed while others fail. But all are treated fairly here.

    Comparing the effects of walking on blood pressure

    Three or four short, brisk walks during the day are more helpful to people watching their blood pressure than one continuous 40-minute work-out in a gym.

    Twenty people with prehypertension (increased blood pressure levels that typically progress to high blood pressure) participated in this study. They walked on a treadmill for 40 minutes on one day. The next day, the same group went for 4, 10-minute walks over 3.5 hours.

    On average, the systolic blood pressure following both forms of exercise dropped a little more than 5 mm Hg. This is significant because a reduction of 5 mm Hg is associated with reduced mortality. However, the response lasted about 11 hours when the group took four 10-minute walks, compared to seven hours when they walked continuously for 40 minutes.

    A person has prehypertension when the systolic blood pressure ranges from 120 to 139 mm Hg or the diastolic pressure ranges from 80 to 89 mm Hg. Another study is going to be done in people with high blood pressure.
