Reducing total fat and other adiposity measures, especially for obese women with the greater exercise proved effective. This proves the fact that physical activity is an inexpensive, noninvasive strategy for disease prevention. Worldwide, public health agencies recommend that for overall health we be physically active for at least 150 minutes a week at moderate intensity, or 60-75 minutes a week at vigorous intensity.
The finding is noteworthy, say the authors from Alberta Health Services in Edmonton, Alberta, Canada, because body fat has been associated with increased risk of postmenopausal breast cancer, so these women may derive unique benefit from exercise.
For the study, the women with body mass indexes (BMI) between 22 and 40 were asked not to change their usual diet.
Doubling the amount of weekly moderate to vigorous aerobic exercise, to 300 minutes instead of 150 minutes a week, had a better effect on body fat in a trial of 400 inactive postmenopausal women.
Reducing total fat and other adiposity measures, especially for obese women, was more effective with the greater exercise during a 1-year clinical trial published in JAMA Oncology.
