Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q1 i? The authors state that physical activity opportunities during the school day are being reduced or eliminated in response to mandates for increased academic classroom time, and that their findings suggest this trend may be counterproductive for achievement. → Chaddock-Heyman L 2015

q1 · i? · associational · r1
Authors' contextual argument in the Discussion, citing policy trends and inactivity statistics rather than presenting new data on this point. They argue their findings provide "additional evidence that increased aerobic fitness levels may enhance cognitive and brain plasticity".
"Physical activity opportunities during the school day are being reduced or eliminated in response to mandates for increased academic classroom time [50], and rising rates of physical inactivity [51– 52]."

Learner Variables¶
- Physical Well-Being — predictor: learners who differ on it differ in outcomes
