Short, Intense Exercise Bursts Improve Teen Cardiovascular Health

For teens, just eight-to-ten minutes of high-intensity interval exercise three times per week can significantly improve both blood vessel function and resting heart rate. University of Exeter’s Dr. Alan Barker adds, “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. This study indicates that, providing the intensity is high, health benefits are achievable with just 8-10 minutes of exercise.”
