An interesting study,
I'm not sure they value the right things when looking at the grades. To me it seems they over-ephasize active transportation when a better metric might just be minutes of physical activity per day. Wether the kid is in the backyard playing after being picked up from school or bking home its the total mintutes of activity.
Its also ignores intensity. Using the example of oragnized sprots like hockey and soccer you go out for an intense shift and then rest then do another intense shift. This studies states that is only partially active because it isn't continuous moderate activity. This is in direct contriditction with studies that show that bouts of high intensity activity can improve health in the same manner as constant moderate activity.
The underlying information is good though. And canada has the facilities in place to have active play. (Though a pile of dirt is all you really need) So its really up to the parents to get kids outside. The big thing preventing this is fear.
