London: Short bursts of sprinting, known as "high intensity exercise", can actually burn 200 calories, much more than jogging or walking for long periods, according to a research.Colorado State University researchers compared the energy expenditure of a group of men on two different days: one spent watching TV, the other doing high-intensity exercise followed by long periods of recovery.To determine how many calories a typical sprint-interval training workout might burn, reserach team leader Kyle Sevits and his colleagues at Colorado recruited healthy male volunteers, aged between 25 and 31 years.Over three days, the men ate a diet calculated to give their bodies exactly the right amount of calories, so they weren`t over or under-eating. One group then spent a day being sedentary, watching TV, while the other group exercised.
