I have written repeatedly about the brain benefits from physical exercise. Asregular readers know, I have a visceral interest in this having lost three family members to dementia. My mother suffered from dementia. Her sister died of Alzheimer’s Disease and my father’s father also was cognitively challenged. That goes back to the mid 1940’s when far less was understood about cognition in general.
Now comes the latest issue of Scientific American with fresh insights into the brain/exercise situation:
People often consider walking and running to be activities that the body is able to perform on autopilot. But research carried out over the past decade by us and others would indicate that this folk wisdom is wrong. Instead exercise seems to be as much a cognitive activity as a physical one….
But simply exercising more may not realize the full potential of physical activity for keeping brain decline at bay. Indeed, our model suggests that even people who already get a lot of aerobic activity may want to rethink their routines. It is possible that we might not always exercise in ways that take full advantage of our evolved mechanisms for sustaining brain performance….
… we have developed a game designed to specifically challenge aspects of cognition that tend to decline with age and that are probably needed during foraging. In the game, players spatially navigate and complete attention and memory tasks while cycling at a moderate aerobic intensity level.
