Walking in short bursts found to consume 20% to 60% more energy than walking continuously for same distance

A team of pathophysiologists at the University of Milan has found that climbing stairs or walking for short bursts allows people to consume 20% to 60% more energy than if they do the same activity nonstop for the same distance. In their study, published in the Proceedings of the Royal Society B, the group asked volunteers to walk on a treadmill or climb stairs while also monitoring their oxygen intake.
