Physically-Fit Kids Have More Robust Brain Function. Children who are physically fit have faster and more robust brain responses during reading than their less-fit peers, a new research shows.

New York: Children who are physically fit have faster and more robust brain responses during reading than their less-fit peers, a new research shows.

These differences are visible when more fit kids are reading straightforward sentences or sentences that contain errors of grammar or syntax.

The new findings, however, do not prove that higher fitness directly influences the changes seen in the electrical activity of the brain, the researchers say.

Although, the research offers a potential mechanism to explain why fitness correlates so closely with better cognitive performance on a variety of tasks?

"All we know is there is something different about higher and lower fit kids. Whether that difference is caused by fitness or maybe some third variable that (affects) both fitness and language processing, we do not know yet," explained Prof. Charles Hillman from the University of Illinois.

The researchers used electroencephalography (EEG), placing an electrode cap on the scalp of children to capture some of the electrical impulses associated with brain activity.

The readouts from the electrodes look like seismic readings captured during an earthquake, and characteristic wave patterns are associated with different tasks.

"These patterns are called 'event-related potentials' (ERPs) and vary according to the person being evaluated and the nature of the stimulus," said Scudder, a graduate student from professor Hillman's team.
