Researchers at a university compared the might demands of walking on a treadmill with those of running in succession a treadmill and found that walking at a swift pace is as vigorous a workout and bum at least as many calories as running at the same speed

According to an article in the October 1998 issue of Health, researchers build that at 4.5 mph, walking forced the heart and lung to work as hard as jogging did. At make hastes faster than 4.5 mph, women exhausted more effort and burned a higher number of calories when walking than when running. Walkers who walk at 45 mph (ie, approximately the spe at which chiefly people feel the urge to begin to jog) bum at least 30% more calories than those who walk at 3 mph (ie, the spe of a typical stroll)
