q2 i? Short bouts (max 20 minutes) mostly showed significant effects while a 45-minute bout showed none, and moderate intensity may be optimal per an inverted-U relationship. → Janssen M 2014

Review's narrative synthesis across 12 studies with bouts of 10–45 minutes; intensity was assessed in eight of them, and in the six laboratory studies it was around 60% of maximum heart rate (moderate). Reports short bouts (max 20 min) mostly significant; the 45-min bout (Pirrie & Lodewyk 2012) showed no effect on attention.

"In the majority of studies that included a short PA bout of maximum of 20 mi- nutes, a significant effect of PA on attention was found. In contrast, in the study from Pirrie and Lodewyk (2012) no effect was found after a 45 minutes PA bout."

q1 · i? · review · r3

Authors' interpretation citing the Yerkes-Dodson inverted-U hypothesis and evidence in mice and adults that moderate PA intensity is optimal for arousal and cognitive performance; offered as an argument, not a tested result.

"Arguably, intensity of PA influences the effect of PA on attention and the effect of PA on attention may follow and inverted U re- lationship."

Learner Variables¶

• Attention — outcome: instruction changes it
