Exercise Improves Cardiovascular
Conditions Of Diabetes And Hypertension Patients
has shown that exercise provides multiple benefits, including improved
cardiovascular functioning, reduction in body fat and an increase in
muscle mass. These changes also help improve sensitivity to insulin and
blood pressure, experts say. As a result of these health improvements,
researchers suggest that exercise may have positive effects on patients
with type 2 diabetes and hypertension.
J. Stewart, Ed.D., of Johns Hopkins School of Medicine, Baltimore,
reviewed medical literature from January 1985 to June 2002 to gather
information on exercise, type 2 diabetes and hypertension. After
performing the search, Stewart developed guidelines for patients with
these conditions based on the articles she reviewed.
analysis evaluated 235 citations from peer-reviewed journals,
professional society guidelines and books.
review of the available data suggests plausible mechanisms by which
exercise training improves the cardiovascular consequences of type 2
diabetes and hypertension, mechanisms that go beyond the established
benefits of exercise on glycemic control and blood pressure reduction,"
recommendations for patients with type 2 diabetes and hypertension
include the following exercises, according to Stewart:
Warm-up and cool-down period of five to 10 minutes each including
Aerobic exercise including walking, cycling and swimming at 55 percent
to 79 percent of maximum heart rate (or 50 percent to 60 percent of
maximum heart rate for patients with low initial fitness levels) for 30
to 45 minutes.
Resistance training, including weight lifting for 20 minutes for one
set each for eight to 10 exercises.
exercise should be done three to four times a week and more frequently
if weight reduction is one of the goals, Stewart said.
