Abstract
INTRODUCTION: This study explored the association between 24-hour movement behaviors and executive function (EF) in preschooers.
METHODS: This cross-sectional study was carried out with 447 preschoolers (242 boys, means age= 4.4 ± 0.9 years). Physical activity (PA) and sedentary behavior (SB) were assessed using an accelerometer for seven consecutive days. Sleep time was obtained through the parent-report questionnaire. Components of EF (cognitive flexibility, inhibitory control, and working memory) were assessed using the computerized behavioral tasks. To verify the association between 24-hour movement behaviors and EF, the compositional data analysis was used, and for the time reallocation, the compositional isotemporal substitution analysis was used.
RESULTS: The daily composition, adjusted for age, gender, and BMI, was significantly associated with inhibitory control (p<0.001; r2= 0.12), and working memory (p<0.001; r2= 0.30). The addition of MVPA at the expense of SB and LPA, LPA at the cost of sleep, were associated with significant inhibitory control improvements. The reallocation between MVPA and LPA yielded significant association with working memory. The impact of MVPA replacing LPA is stronger than MVPA re- placing SB on inhibition control.
CONCLUSION: These findings highlight the importance of maintaining or increasing MVPA in EF development in pre- schoolers.
