Physical Activity Boosts Kids’ Brains
Physical and intellectual fitness go together, researchers found in a study of 24 kids ages 9 and 10. A special type of imaging showed that kids who performed better on treadmill tests had stronger “white matter,” the parts of the brain that carry nerve signals from region to region. Such nerve activity leads to better communication within the brain and potentially greater ability to think. While the researchers didn’t test the kids’ smarts, previous studies have shown a link between improved physical fitness and better school performance. And stronger white matter in particular has been linked to better math skills.
