If you want a young person to focus intently in school and perform well on tests, should you first send him or her to gym class? That question, which has particular relevance for school districts weighing whether to reduce or ax their physical education programs to save money, motivated a number of stimulating new examinations into the interplay of activity and attention. Some of the experiments studied children; others looked at laboratory rats bred to have an animal version of attention deficit disorder. For both groups, exercise significantly affected their ability to concentrate, although some activities seemed to be better than others at sharpening attention.
The most striking of the new studies involved 138 schoolchildren ages 8 to 11 who were living in Rome. The children were physically healthy, and none suffered from serious attention deficits. But like most children that age, they found it difficult to remain fully engaged in their lessons as the school day wore on. As the study’s authors, all affiliated with the Foro Italico campus of the University of Rome, point out, children “who undergo prolonged periods of academic instruction often reduce their attention and concentration.”
To determine whether exertion could make students less distracted, the researchers, whose study was published last week in Medicine & Science in Sports & Exercise, had the children complete several types of gym classes, as well as a typical instructional or lecture class. Just before and immediately after the classes, the children took a written test that required them to pick out certain letters from long chains of symbols in a short time. The test is widely accepted as a good indicator of a person’s attention and ability to concentrate.
