Running has been my primary form of exercise
for several years now. The coach was telling some us a while back about some study
he'd seen claiming that distance running
on a regular basis
actually improved your brain functions. He correlates this with the fact that track
program at my school has, over a sampling of the past 50 years, had more total honor roll
students than any other athletic program.
The study supposedly said that regular running stimulated and augmented blood flow to your brain, meaning it got more oxygen and was able to function better in all respects. So not only is running a fairly enjoyable and beneficial excercise, but it makes you smarter, too!
No wonder football players get the dumb stereotype...
