The influence of removing the 10-minute bout requirement on the demographic, behaviour and health profiles of Canadian adults who meet the physical activity recommendations

The physical activity (PA) recommendation was recently revised in the Canadian 24-Hour Movement Guidelines for Adults. The 150 minutes per week of moderate-to-vigorous intensity PA (MVPA) went from requiring that MVPA be accrued in bouts of 10 minutes or more (bouted) to having no bout requirement (non-bouted). Using adult accelerometer data from three combined cycles of the nationally representative Canadian Health Measures Survey, this study compared adherence to the bouted and non-bouted recommendations, and assessed differences in sociodemographic, health and fitness measures.
