March 9, 2004 -- Getting at least 30 minutes a day of exercise not only helps prevent heart problems, but it should also be a part of the prescription for treating people with high blood pressure, according to a new report.

Revised guidelines on exercise and hypertension released today by the American College of Sports Medicine indicate that exercise should be a cornerstone of therapy for the prevention, treatment, and control of high blood pressure, and getting the recommended daily dose may not necessarily require working up a sweat.

"Moderate-intensity exercise has been scientifically documented to effectively lower blood pressure in people, perhaps more so than vigorous-intensity exercise," says Linda Pescatello, PhD, who was co-chairwoman of the panel that compiled the report. Moderate-intensity exercise includes walking, biking, and other activities that moderately raise the heart rate.

Pescatello says that news is especially good for people with hypertension who are more susceptible to potential health risks from more vigorous exercise, such as running.

"The fact that the evidence shows that moderate intensity exercise is preferred actually optimizes the blood pressure-lowering capacity of exercise for these people while minimizing risk," says Pescatello, who is also associate professor and director of the Center for Health Promotion at the University of Connecticut.

The complete report appears in the March issue of Medicine & Science in Sports & Exercise.

Daily Exercise Recommended

Researchers say the guidelines replace ones issued in 1993 and contain a greater emphasis on consistent, moderate-intensity physical activity and resistance exercise (such as weight training) as a vital part of treating and preventing high blood pressure. Previous recommendations called for more vigorous exercise on three to five days of the week.

The new guidelines call for 30 minutes of moderate-intensity physical activity (primarily aerobic exercise, which helps get heart rates to 70%-85% of an individual's maximal heart rate, or endurance exercise supplemented by resistance exercise) on most, preferably all days of the week for people with hypertension. The 30 minutes can be at once or accumulated during the day, such as in three 10-minute walks. These recommendations are in line with national physical activity guidelines for healthy adults issued by the CDC.
