A research from Spain shows that women who walk at least three hours every week are less likely to suffer a stroke than women who walk less or not at all.
The researchers who conducted the study say that it contributes to a small body of evidence for potential relationships between specific kinds of exercise and risk for specific diseases. Women who walked briskly for 210 minutes or more per week had a lower stroke risk than inactive women but also lower than those who cycled and did other higher-intensity workouts for a shorter amount of time.
The results for women who were regular walkers translated to a 43 percent reduction in stroke risk compared to the inactive group.
The authors, who published their findings in the journal Stroke, checked in with participants periodically to record any strokes. During the 12-year follow-up period, a total of 442 strokes occurred among the men and women who took part. There was no reduction seen, however, for men based on exercise type or frequency.
Past studies have also linked physical activity to fewer strokes, which are caused by built-up plaque in arteries or ruptured blood vessels in the brain.
