By GRETCHEN REYNOLDS
It has long been a cliché that muscle bulk doesn’t equate to intelligence. In fact, most of the science to date about activity and brain health has focused on the role of endurance exercise in improving our brain functioning. Aerobic exercise causes a steep spike in blood movement to the brain, an action that some researchers have speculated might be necessary for the creation of new brain cells, or neurogenesis. Running and other forms of aerobic exercise have been shown, in mice and men, to lead to neurogenesis in those portions of the brain associated with memory and thinking, providing another compelling reason to get out at lunchtime and run.
