Or count how many steps you take in a single minute and skip the multiplication altogether. Or count how many steps you take in six seconds and multiply by 10. Just count how many steps you take in 10 seconds and multiply that number by six, she says. “You do not need special equipment or expertise.” “This is a number that is very easy for any of us to measure on our own,” she says. Or put more simply, it required about 100 steps per minute. Tudor-Locke and her colleagues found.īrisk walking involved a pace of about 2.7 miles per hour. They wound up with 38 studies that had included hundreds of men and women ranging in age from 18 to elderly and of many different B.M.I.s.īut despite the differences in the participants, the data about what made their walking brisk, or “moderate,” was consistent across all of the studies, Dr. They also wanted to find studies that had examined people of varying ages and body mass indexes, to see if a single measure of what makes walking brisk could apply to almost everyone. They wanted to see if there were consistencies between an easy-to-use number, such as steps per minute, and more technical determinations of intensity, such as respiration. They began by looking for recent, good-quality published studies that had tracked people’s walking pace and cadence, which is the number of steps they take per minute, as well as other measures of their effort, such as heart rate or increases in respiration. So, for the new study, which was published in June in a special issue of the British Journal of Sports Medicine devoted to the topic of walking, she and her colleagues decided to see whether there was enough data already available to develop a more precise and useful definition of brisk walking. “Who wants to sing when they walk?” she asks. That definition seemed impractical to Catrine Tudor-Locke, a professor of kinesiology at the University of Massachusetts in Amherst, who has long studied how much exercise might be needed or sufficient for health. Used by the Centers for Disease Control and Prevention and other agencies in their guidelines, it defines brisk walking (and other moderate-intensity activities) as occurring at a pace at which people can talk but not sing. Even the simplest, often-cited description of brisk walking can be vague and confusing.
