In a longitudinal study of exercise results for men and women, the men have a decided advantage when it comes to stroke risk:
“Moderate-to-high intensity exercise such as jogging, swimming or tennis may help reduce stroke risk in older men but not in women, researchers report.
The study included almost 3,300 men and women, average age 69, in Manhattan who were followed for about nine years. During that time, there were 238 strokes among the participants. At the start of the study, 20 percent of the participants said they did regular moderate-to-high intensity exercise, while 41 percent said they did no physical activity.”
