A study of over 100 men and women shows that walking as exercise may not be enough to produce significant health benefits.
The study compared a popular walking exercise program to a more traditional fitness routine incorporating cardio-based activities on treadmills and stationary bicycles.
The traditional group was asked to exercise at a moderate intensity, whereas the walking group was allowed to go at a self-selected pace.
The traditional fitness program improved aerobic fitness and reduced systolic blood pressure more than the walking program. Those who took part in the active regimen increased their peak oxygen uptake by 10 percent, compared to 4 percent for the other group.
Systolic blood pressure also dropped by 10 percent for the traditional group and 4 percent for the walking group.
