cross-posted from: https://beehaw.org/post/16413694 Appropriate levels of physical activity, sedentary behaviour and sleep (collectively termed movement behaviours) are essential for the healthy growth and development of preschool-aged children. This was the impetus for creating the Canadian 24-Hour Movement Guidelines for the Early Years (birth to four years). Likewise, this is why the World Health Organization adopted the Canadian guidelines when creating the global guidelines on physical activity, sedentary behaviour and sleep for children under five years of age. Considering the extensive benefits of movement behaviours, it is very alarming that a recent study found that only 14 per cent of preschoolers around the world are meeting movement behaviour guideline recommendations.
