Exercise is good for the brain. We know that. But most studies of exercise and brain health have focused on the effects of running, walking or other aerobic activities.
Now a new experiment suggests that light resistance training may also slow the age-related shrinking of some parts of our brains.
Our brains are, of course, dynamic organs, adding and shedding neurons and connections throughout our lifetimes. They remodel and repair themselves constantly, in fact, in response to our lifestyles, including whether and how we exercise.
But they remain, like the rest of our bodies, vulnerable to the passage of time. Many neurological studies have found that, by late middle age, most of us have begun developing age-related holes or lesions in our brains’ white matter, which is the material that connects and passes messages between different brain regions.
