Walking healthier than running

hikingBrisk walking reduces the risk of heart disease more effectively than running when the energy expenditure of both activities is balanced out according to a new study published in the American Heart Association journal, Arteriosclerosis, Thrombosis and Vascular Biology.

Researchers compared data from two studies of 33,060 runners and 15,045 walkers. For the same amount of energy used, walkers experienced greater health benefits than runners.

The effects on participants, who were aged 18 to 80, were observed over a period of six years and it was observed that although running reduced the risk of heart disease by 4.5%, walking reduced it by more than double at 9.3%.

Calorie for calorie, walking also had a stronger impact on heart disease risk factors with the risk of first-time high blood pressure being reduced by 4.2% by running as compared to 7.2% by walking.

First-time high cholesterol risk was lowered by 4.3% by running and 7% by walking, and the risk of first-time diabetes was reduced by about 12% by both walking and running.

“Walking and running provides an ideal test of the health benefits of moderate-intensity walking and vigorous-intensity running because they involve the same muscle groups and the same activities performed at different intensities,” said study leader Dr Paul Williams, from the Lawrence Berkeley National Laboratory in California.

“The more the runners ran, and the walkers walked, the better off they were in health benefits. If the amount of energy expended was the same between the two groups, then the health benefits were comparable.
“People are always looking for an excuse not to exercise but now they have a straightforward choice to run or to walk and invest in their future health.”
