The September issue of WellSpring, a monthly online publication by the Alberta Centre for Active Living for practitioners, features an article by HALO Director Dr. Mark Tremblay and Research Manager Dr. Veronica Poitras titled, “Integrating physical activity, sleep and sedentary behaviour — a world first!

In this article, they write about the new Canadian 24-Hour Movement Guidelines for Children and Youth: An Integration of Physical Activity, Sedentary Behaviour, and Sleep, summarizing the background research, consultations, implications, and process to develop the guidelines.

From the article:

It is becoming clear that behaviours along the movement continuum (i.e., physical activity, sedentary behaviour and sleep) interact, such that their combined effects on health extend beyond the individual contributions of each behaviour (Figure 1). For example, the benefits of moderate- to vigorous-intensity physical activity can be reduced if children have poor sleep habits or engage in excessive sedentary behaviours (like screen time). Conversely, increased physical activity could attenuate the negative effects of insufficient sleep and/or extended periods of sitting in some individuals.1 Therefore, it is the combination of movement behaviours that is important with respect to health.
