How well children perform in the classroom could be linked to how physically active they are, suggests a Dutch review of previous studies.

Writing in Archives of Pediatrics & Adolescent Medicine, researchers said they found strong evidence of a link between exercise and academic performance.

The review looked at 14 studies involving more than 12,000 children.

Exercise may help by increasing blood and oxygen flow to the brain, it said.
