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, according to research from Spain that looked at thousands of people.

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, according to research from Spain that looked at thousands of people.

While the current study, which appeared in the journal Stroke, cannot prove that regular walking caused the fewer strokes, it contributes to a small body of evidence for potential relationships between specific kinds of exercise and risk for specific diseases.

Past studies have also linked physical activity to fewer strokes, which can be caused by built-up plaque in arteries or ruptured blood vessels in the brain.

“The message for the general population remains similar: regularly engaging in moderate recreational activity is good for your health,” lead author Jose Maria Huerta of the Murcia Regional Health Authority in Spain told Reuters Health.

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.

In all, nearly 33,000 men and women answered a physical activity questionnaire given once in the mid-1990s as part of a larger European cancer project. For their study, Huerta and his team divided participants by gender, exercise type and total time spent exercising each week.

The authors 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.

The results for women who were regular walkers translated to a 43 percent reduction in stroke risk compared to the inactive group, Huerta said. There was no reduction seen for men based on exercise type or frequency.
