A study from Lawrence Berkeley National Laboratory in California has suggested that as long as you’re expending energy, the speed doesn’t matter.
At least, that’s the findings from an astonishing six-year-long study on over 48,000 runners and walkers. It showed:
|Risk of developing||Running||Walking|
|Heart disease||down 4.5%||down 9.3%|
|High blood pressure||down 4.2%||down 7.2%|
|High cholesterol||down 4.3%||down 7%|
|Type 2 diabetes||down 12%||down 12%|
The catch? The amount of energy expended needs to be equal – so to achieve the same results a walker will have to walk much further and for longer than a runner would need to run.
“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.
“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.
