Children who are physically fit are out-performing those who do not take part in regular physical exercise or organised sport, a new study has found.
Researchers also found that the more physical exercise or structured sport that students do, the better they perform with their classwork, the Daily Telegraph reported.
Sedentary children are at risk of their academic results falling away, the researchers have told the federal government in a landmark report.
Parents not ensuring their children get at least ten hours sleep during the week are contributing to their kids' bulging waistlines.
Research by a specialist team at the University of Wollongong, which has presented its findings to the federal Department of Health and Ageing, shows "30 to 40 minutes of physical activity per day has demonstrated benefits for kids' cognitive and academic development."
The report titled 'A Systematic Review to Inform Physical Activity Guidelines for Children and Young People' shows a clear link between physical exercise and academic achievement.
"There is a dose-response relationship between physical activity and cognitive development/academic achievement - the more the better," Wollongong University's Dr Stewart Vella said.
"The benefits (of exercise) are substantial ... and the more physical activity (students) do the greater increase in grades," Vella added.
International researchers have suggested that exercise increases the flow of blood and oxygen to the brain and may lead to increased levels of norepinephrine and endorphins, which are important in stress reduction. (ANI)
