Boys’ results different from girls’
One notable finding was that physical activity affected academic outcomes differently for boys and girls.
Girls who participated in organized sports were about 7 per cent more likely to earn a high-school diploma or equivalent. Participation in organized or artistic sports was also associated with higher grades for girls.
By contrast, girls who engaged in unstructured physical activity had lower average grades at age 18.
For boys, only one correlation emerged from the results: those who participated in organized sports were almost 15 per cent more likely to have a high school diploma or equivalent by age 20.
Why do organized sports make a difference? Organized sports “require structure, usually by the implementation of rules and objectives,” the authors write in their study.
“When supervised by an adult and often in teams, sports allow children to develop key skills in various areas—leadership, behaving in a group, prolonged attention—that can be transferred to academic classes.
Cautioned Pagani: “We must bear in mind that our findings are based on data collected between 1996 and 2001, well before the explosion of screens and digital platforms. Confounding factors are likely to be greater and potentially more challenging today.”
