Walking as good as running for heart disease
It may be time to rethink that exercise regime. Researchers at the Lawrence Berkeley National Laboratory, Life Science Division in California have found that brisk walking can be just as effective as running in reducing the risk of developing diabetes, high blood pressure and high cholesterol.
Unlike previous studies which focused on the amount of time a person walked or ran, this analysis determined that as long as the energy expended was equivalent, so were the benefits. Thus, higher intensity exercise was no better at reducing these health risks than moderate-intensity walking.
This study examined 33,060 runners in the National Runners' Health Study and 15,045 walkers in the National Walkers' Health Study over a six-year period. The results showed that the risk for hypertension was reduced 4.2 percent by running and 7.2 percent by walking; risk for high cholesterol was reduced by 4.3 percent by running and 7 percent by walking; risk of diabetes was lowered 12.1 percent by running and 12.3 percent by walking; and the risk of coronary heart disease was lowered 4.5 percent by running and 9.3 percent by walking.
