Related Claims¶
- Classroom physical activity increases children's on-task behaviour, with no consistent gain on attention or other cognitive tests — the general claim this finding bears on, with the studies behind it
- Teachers in Playworks schools reported less bullying and exclusionary behavior during recess than control-school teachers — a narrower finding that bears on this claim
- Playworks made transitions from recess to classroom learning less difficult, per teacher reports — a narrower finding that bears on this claim
- Girls in Playworks schools had significantly higher accelerometer intensity counts and spent more time in vigorous physical activity than girls in control schools — related
- In a randomized controlled trial, children in Playworks schools spent more time in vigorous physical activity at recess than students at non-Playworks schools, and more teachers in Playworks schools reported students engaged in intense recess activity — related
- Girls in Playworks schools were less likely to be sedentary and more likely to engage in jumping, tag, and playground games during recess — related
- No significant accelerometer-based differences in physical activity were found for boys in Playworks schools compared with control schools — related
