Exercise your brain

It turns out that the old adage about how a healthy body leads to a healthy mind is being proven in the classroom

Brothers Theo, 11, and Loic Tremblay, 7, play street hockey close to their home in Outremont, last summer. Studies have shown that exercise just before tackling schoolwork can boost children's academic performance.

MONTREAL - Can't get your kids to concentrate on their homework? Don't nag. Send them out for a quick game of road hockey instead. Researchers report kids perform better academically after working up a sweat than after a day spent sitting around a classroom.
The idea that exercise and academic success go hand and hand is gaining more credibility. To the delight of physical education teachers everywhere, the message is filtering down to school administrators.
Naperville Central High School, located just outside Chicago, decided to see what would happen if they got some of their underperformers moving. Kids who scored poorly in math or reading went to the gym before sitting down to tackle a series of equations or read an assigned chapter of their text book.
The results were astounding. Kids who had previously struggled with school work improved their reading skills to the point where they were reading a year and a half above their grade level. Math scores rose by 21 per cent.
This small experiment jives with some of the latest research. Study ,after study reports not only that exercise has an immediate effect on test scores, but that fit kids do better in school than kids who don't exercise.
Physical activity, it seems, does more than just strengthen muscles; it strengthens the brain, too. Scientists suggest that kids who exercise on a regular basis solve problems faster than kids who don't. Fit kids are also more attentive and score higher when tested for accuracy.
The evidence is so strong that it's difficult to suggest that more time in study hall is the only answer to better grades. That being said, researchers are less clear about exactly how much exercise is needed to turn Cs into As. One of the first studies to try to pinpoint the exercise prescription necessary to stimulate learning was done in Trois Rivières and published in 1994. It stated that children who exercised an hour a day over and above their regular school gym class were more successful academically than students who got their exercise in gym class only.
Other studies suggest that only vigorous activity results in better academic performance, and some suggest that girls who exercise receive more scholastic benefit than active boys. As for how much exercise it takes to improve grades, the number varies from as low as 20 minutes a day to as high as 60 minutes. Also, elementary and middle school students are more suggestive to exercise interventions than high school students.
As for organized sport, that too has a positive effect on kids' report cards. A January 2010 article in the Journal of School Health reported that the grade-point averages for high school students who played on sports teams were higher than those who sat on the sidelines. It also reported that the more teams the students played on, the greater the boost to their GPA.
This wide spectrum of results is indicative of the complexity of collecting and evaluating exercise habits. Most people are generous when it comes to recounting the amount of time spent exercising. Then there's the difficulty of determining exercise intensity - what's moderate for some is easy for others.
There are less subjective ways to quantify physical activity. Pedometers and accelerometers measure daily activity, but are expensive, especially for large study samples.
That being said, there seems to be an agreement among researchers that not all exercise is equal in its ability to improve academic success. Aerobic exercise has proven more effective at boosting kids' test scores than muscular conditioning or stretching. And more exercise versus less produces more dramatic scholastic improvements.
Also interesting to note is that not all academic subjects reap the same benefits from exercise. Math scores seem to respond best to a bout of exercise compared with other subjects like English, history or geography.
Armed with the latest research, schools need to look at ways to incorporate more physical activity into the curriculum rather than less. Naperville High School went so far as to equip classrooms with stationary bikes and exercise balls, which allow students to exercise without leaving the classroom.
With that in mind, study hall may want to incorporate a little 4-on-4 soccer and math class should be scheduled right after gym class.
Parents should also rethink how their kids schedule homework. Take the family out for a bike ride or trip to the park before the kids hit the books after school. And participation in community or school-based sports should be encouraged and thought of as an academic asset, not a deterrent.
Keeping kids attentive and successful in school is the key to long-term academic success. And habits learned early are habits that tend to stick. So get out there with your kids and show them that exercise is not only the way to better health, it's also the way to better grades
