Abstract
Purpose: This study investigated the associations between physical activity (PA), sedentary behavior (SB) and executive function (EF) in preadolescents.
Methods: One hundred and twenty preadolescents were recruited from two Hong Kong primary schools. PA and SB were recorded for seven consecutive days by accelerometer. EF performance, including inhibition (Stroop task, ST; Flanker task, FT) and working memory (Sternberg Paradigm task, SPT) were measured. Body mass index (BMI) and cardiorespiratory fitness (CRF, multi-stage fitness test) were tested. Latent profile analysis explored the profiles of PA and SB in preadolescents.
Results: Three distinct profiles were identified: Low Activity, Average Activity, and High Activity. Participants in Low Activity performed worse in the accuracy of ST (vs. Average Activity, P = 0.03; vs. High activity, P < 0.01), FT (vs. Average Activity, P = 0.02; vs. High activity, P < 0.001), and SPT (vs. Average Activity, P < 0.01; vs. High activity, P < 0.01). No significant difference was observed between participants with Average Activity and High Activity. No significant association was observed for profiles on BMI and CRF.
Conclusion: Supplementing the consensus of the literature that moderate-to-vigorous physical activity benefits cognition, we conclude that light physical activity enhances preadolescents' executive functioning.
