Every month in the print edition of 'Men's Journal,' Dr. Robert Mordkin, the chief of urology and director of robotic surgery at Virginia Hospital Center, surveys the nation's top doctors about men's health issues. Here, he talks to Dr. Barry Gordon, professor of neurology and cognitive science at Johns Hopkins Medical Institutions and author of 'Intelligent Memory,' about the impact that exercise has on the brain.
Is the type of exercise important?
Aerobic fitness is probably the best, but some studies have shown benefits from resistance training. Stretching – used as a control at times – has not shown any benefit. In terms of duration and effort, the best evidence seems to be for what's called a dose-response curve: That is, any exercise is beneficial. If you are physically active your whole life, it is predictive of better cognitive abilities later in life.
