An article by Anna-Liisa Kyhälä, Jyrki Reunamo ja Heikki Ruismäki titled Preschool Children are more Physically Active and less Sedentary on Weekdays Compared with Weekends has just been accepted for publication in Journal of Early Childhood Education Research. In the article, it can be seen clearly that it is not enough to look at the average amount of physical activity, children’s differences are also important. Furthermore, because children seem to less physically active during weekends, sufficient physical activity in day care center is even more important.
