For young adults who exercise a bit, doing a quick 9-minute sprint workout leads to bigger drops in muscle power—like how high you can jump or how strong your legs and arms feel—compared to other similar workouts using burpees or steady hard exercise.
After a quick 9-minute workout, sprint intervals might make your heart take longer to calm down compared to burpees or steady hard exercise — at least in young, somewhat active people.
Sprint and hard steady workouts get your heart pumping faster and keep it near maximum longer than burpee workouts in young, somewhat active people — at least during 9-minute sessions.
Sprinting might help you stay younger on the inside by keeping your muscles, nerves, and metabolism in top shape.
