Research had found that short bursts of exercise for teens reduce heart disease risk.
Exercise bursts of 8 to 10 minutes have the same effects on markers for cardiovascular disease as the currently recommended 60 minutes of daily exercise.
The small study in England supports other studies, showing similar effects in young children, and help to hold off diabetes in adults.
While teens in England are recommended at least 60 minutes of exercise a day, national surveys show that only 30 percent of boys and 20 percent of girls get this amount of exercise.
“We know that activity levels drop significantly as children reach adolescence, and so far attempts to increase this to an hour a day have proved fruitless,” said Dr. Alan Barker, a professor at the University of Exeter, in a press release. “This study indicates that, providing the intensity is high, health benefits are achievable with just 8-10 minutes of exercise.”
