March 26, 2007 issue - The stereotype of the "dumb jock" has never sounded right to Charles Hillman. A jock himself, he plays hockey four times a week, but when he isn't body-checking his opponents on the ice, he's giving his mind a comparable workout in his neuroscience and kinesiology lab at the University of Illinois. Nearly every semester in his classroom, he says, students on the women's cross-country team set the curve on his exams. So recently he started wondering if there was a vital and overlooked link between brawn and brains?if long hours at the gym could somehow build up not just muscles, but minds. With colleagues, he rounded up 259 Illinois third and fifth graders, measured their body-mass index and put them through classic PE routines: the "sit-and-reach," a brisk run and timed push-ups and sit-ups. Then he checked their physical abilities against their math and reading scores on a statewide standardized test. Sure enough, on the whole, the kids with the fittest bodies were the ones with the fittest brains, even when factors such as socioeconomic status were taken into account. Sports, Hillman concluded, might indeed be boosting the students' intellect...</p>

<p>...Scientists have always suspected as much, although they have not been able to prove it. The idea of the "scholar-athlete" isn't just a marketing ploy dreamed up by the NCAA; it goes back to the culture of ancient Greece, in which "fitness was almost as important as learning itself," says Harvard psychiatrist John Ratey. The Greeks, he adds, were clued into "the mind-body connection....</p>

<p>...Finally, there's the question that's been dogging Charles Hillman since he first picked up a hockey stick: why, if jocks on average have more capable brains than the rest of the public, do they have an unfair reputation for being dumb? Why does a term like "scholar-athlete," which would have made so much sense to the ancient Greeks, get snickered at today? The reason, says Hillman, is found not in science but in common sense: some of our schools have failed young athletes by cutting them too much slack. "A lot of it comes from schools' giving them an easy road," he says. "Kids get this wholly inaccurate label because they're good at sports, and then too much emphasis is placed on their physical abilities at the expense of their mental abilities.""
