The optimal amount of movement, the researchers found, was five minutes of walking every 30 minutes. Participants were allowed to work on a laptop, read, and use their phones during the sessions and were provided standardized meals. Researchers kept an eye on each participant to ensure they did not over- or under-exercise and periodically measured the participants’ blood pressure and blood sugar (key indicators of cardiovascular health). “If we hadn’t compared multiple options and varied the frequency and duration of the exercise, we would have only been able to provide people with our best guesses of the optimal routine,” Diaz says.Įach of the 11 adults who participated in the study came to Diaz’s laboratory, where participants sat in an ergonomic chair for eight hours, rising only for their prescribed exercise snack of treadmill walking or a bathroom break. Unlike other studies that test one or two activity options, Diaz’s study tested five different exercise “snacks”: one minute of walking after every 30 minutes of sitting, one minute after 60 minutes five minutes every 30 five minutes every 60 and no walking. The study, led by Keith Diaz, PhD, associate professor of behavioral medicine at Columbia University Vagelos College of Physicians and Surgeons, was published online in Medicine & Science in Sports & Exercise, the journal of the American College of Sports Medicine. Now a study by Columbia University exercise physiologists has an answer: just five minutes of walking every half hour during periods of prolonged sitting can offset some of the most harmful effects. But how often do we need to get up from our chairs? And for how long?įew studies have compared multiple options to come up with the answer most office workers want: What is the least amount of activity needed to counteract the health impact of a workday filled with sitting?
