7 Healthcast: Study: Students do better on tests after physical activity
If you're looking to boost your child's grades, getting them out of the classroom may be a good idea.
A new study in the March issue of "Medicine and Science in Sports and Exercise" says physical activity right before a test helps kids do better by increasing blood flow to the brain and releasing good hormones to balance mood and help with concentration.
Abilities to process increased by 10 percent and concentration increased, too.
The same group scored higher after using mental exercises too like memory games or pretests.
The study also found students who went through physical and mental exercises before a test did not score as high as when they had just one form of exertion.
Researchers say too much mental and physical activity combined could be simply overwhelming for kids.
