A large study published in Stroke found that women who walked two or more hours a week or walked briskly lowered the risk of stroke by more than a third.
The researchers followed nearly 40000 women aged over 44 for about 12 years to investigate the link between the levels of physical actitivity and the risk of having a stroke. The participants reported periodically on their physical activities via a questionnaire. 579 women had a stroke during the follow-up years.
The researchers said they have found a borderline significant link between the time spent on physical activities and stroke risk but they did not find a link between vigorous activity and reduced stroke risk. The lead author said the study was observational and physical activity was self-reported, further study is needed on more hemorrhagic strokes and with more ethnically diverse women.
