Brisk walking reduces the risk of heart disease more effectively than running when the energy expenditure of both activities is balanced out, a study has found.

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.

The effects on participants, who were aged 18 to 80, were observed over six years.

Running reduced the risk of heart disease by 4.5pc while walking reduced it by 9.3pc.

Calorie for calorie, walking also had a stronger impact on heart-disease risk factors. The risk of first-time high blood pressure was reduced by 4.2pc by running and 7.2pc walking.

First-time high-cholesterol risk was lowered by 4.3pc by running and 7pc by walking.

The risk of first-time diabetes was reduced by about 12pc by both walking and running.

"Walking and running provide 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, US.

"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, then the health benefits were comparable."

The research is reported in the 'American Heart Association journal Arteriosclerosis, Thrombosis and Vascular Biology'.
