Postmenopausal women: Walk farther and faster to reduce heart failure risk
FROM ACC18
Overall, the risk of heart failure was 20%-25% less for women who walked at least twice a week than it was for women who walked less frequently. In addition, women who walked for at least 40 minutes per walk had a 21%-25% lower heart failure risk than did those who walked less than 40 minutes per walk.
Pace mattered as well, Dr. Rasla pointed out. Women walking at an average pace and a fast pace had, respectively, 26% and 38% lower heart failure risk, compared with women who walked at a casual pace.
The researchers measured the women’s energy expenditure using the Metabolic Equivalent of Task (MET), a value calculated using the women’s self-reports of their walking frequency, duration, and speed. The results were similar across different age groups, ethnicities, and baseline body weight, which suggests the findings can be generalized to apply to most women. “I think we could give the same advice [about walking] to women up to age 79,” said Dr. Rasla.
The findings were limited by the use of self-reports, Dr. Rasla noted. However, the results suggest that walking can be a valuable and accessible form of exercise for older women, he said.
The Women’s Health Initiative is sponsored by the National Institutes of Health. The investigators reported no relevant conflicts of interest.
