Washington: A new study by researchers at Queen`s University has determined that adults who accumulated 150 minutes of exercise on a few days of the week were not any less healthy than adults who exercised more frequently throughout the week.
Ian Janssen and his graduate student Janine Clarke studied 2,324 adults from across Canada to determine whether the frequency of physical activity throughout the week is associated with risk factors for diabetes, heart disease and stroke.
"The findings indicate that it does not matter how adults choose to accumulate their 150 weekly minutes of physical activity," Dr. Janssen said.
"For instance, someone who did not perform any physical activity on Monday to Friday but was active for 150 minutes over the weekend would obtain the same health benefits from their activity as someone who accumulated 150 minutes of activity over the week by doing 20-25 minutes of activity on a daily basis," he said.
Physical activity was measured continuously throughout the week by having research participants wear accelerometers on their waists. Accelerometers are tiny electrical devices (about the size of a small package of matches) that record how much a person moves every minute.
The research is published in the journal Applied Physiology, Nutrition and Metabolism.
