Regular exercise could take teens' grades from C to B
REGULAR exercise boosts teenagers' school grades - and particularly helps girls in science, a British study said yesterday.
The more physically active they were, the better children performed in school, according to findings published online in the British Journal Of Sports Medicine.
And "girls' science results seemed to benefit the most", said a press statement.
The study's authors suggested that students who meet guidelines of being active for 60 minutes a day could raise their average grade in the General Certificate of Secondary Education exams taken at age 15 to 16 from C to B, Dr John Reilly, a professor of physical activity and public health science at the University of Strathclyde, said.
Because even the most active children got less than 60 minutes of exercise a day, the effect is speculative. Physical activity has long been suspected to boost brainpower, but little scientific evidence has existed until now.
For the study, researchers from England, Scotland and the United States measured the level of physical activity among nearly 5,000 11-year-olds who wore a motion-reading "accelerometer" for a week.
Their academic performance in English, maths and science was then assessed at the ages of 11, 13 and 16. Children who had been more physically active at 11 performed better in all three phases and all three subjects.
