Examining Associations Between Physical Activity and Academic Performance in a Large Sample of Ontario Students: The Role of Inattention and Hyperactivity.

BACKGROUND: Participation in physical activity (PA) is a modifiable factor that contributes to academic success, yet the optimal dose (ie, frequency) and mechanisms underlying the effect require further exploration. METHODS: Using data from 19,886 elementary and 11,238 secondary school students across Ontario, Canada, this study examined associations between PA participation frequency, academic achievement, and inattention and hyperactivity.
