| Long-term
exercise can control blood pressure as well as drugs, according to a study reported
in the January issue of the journal Medicine and Science in Sports and Exercise. Exercise
has been well documented to exert a beneficial effect on cardiovascular health,
but this is the first study to determine the long-term effect of regular training
as a monotherapy on both blood pressure at rest and during exercise. Researchers
from Humboldt-University in Berlin studied 10 subjects with hypertension and an
average age of 43 years to determine their blood pressure response to long-term
aerobic training. Blood
pressure measurements were obtained at rest and during exercise. Patients were
instructed to exercise 120 minutes a week. After
18 months of training, the blood pressure of the participants dropped at rest
from 139 to 133 mm Hg on average and during exercise from 184 to 172 mm Hg on
average. After
three years of training, the blood pressure of the participants continued to decrease
significantly to an average of 130 mm Hg at rest and an average of 167 mm Hg during
exercise. No significant changes in body weight were documented during the training
period. "Long-term
aerobic exercise is associated with a decrease in blood pressure at rest and during
exercise, which is comparable to that of drug therapies," concluded the researchers. Other
