Washington: Researchers have claimed that kids who are physically fit have faster and more robust neuro-electrical brain responses during reading than their less-fit peers.
According to the researchers, new findings do not prove that higher fitness directly influences the changes seen in the electrical activity of the brain but offer a potential mechanism to explain why fitness correlates so closely with better cognitive performance on a variety of tasks.
University of Illinois kinesiology and community health professorÂ Charles Hillman, who led the research with graduate studentÂ Mark ScudderÂ and psychology professorÂ Kara Federmeier, said all they know is there is something different about higher and lower fit kids. He said that now whether that difference is caused by fitness or maybe some third variable that (affects) both fitness and language processing, they don’t know yet.
The researchers usedÂ electroencephalographyÂ (Â EEG), placing an electrode cap on the scalp to capture some of the electrical impulses associated with brain activity. The squiggly readouts from the electrodes look like seismic readings captured during an earthquake, and characteristic wave patterns are associated with different tasks.
