24 h Movement Behavior and Executive Function in 4～6-Year-Old Children:A Compositional and Isotemporal Reallocation Analysis Based on Embodied Cognition
Based on embodied cognition theory,this paper employed compositional data analysis to explore the relationship between 24-hour movement behavior and children's executive function(EF),and further analyzes the impact on EF of different activity components following isochronous substitution.A total of 103 children aged 4～6 years(50females,53 males)were measured for 24-hour movement behavior using the ActiGraph wGT3-BT accelerometer and subjective sleep reports.Their EF was assessed using a task paradigm developed in E-prime 3,and all statistical analyses were performed in RStudio software.The results showed that the children's moderate-to-vigorous physical activity(MVPA)did not meet the standards recommended by the World Health Organization,while sedentary behavior(SB)time was excessive.There was a possibility of conversion between MVPA and light physical activity(LPA),but MVPA time overall was stable.24-hour movement behavior was related to EF.MVPA and sleep period(SP)were positively correlated with EF,while SB was negatively correlated with EF.LP A showed no significant relationship with EF.Isochronous substitution of MVPA for SB or LPA significantly enhanced EF,with the highest benefit observed when replacing LPA.Conversely,when MVPA was replaced by SB or LPA through isochronous substitution,EF quickly declined.It indicated that from the perspective of embodied cognition,24-hour movement behavior,particularly MVPA and SP,played a significant role in the development of EF in children.It suggested that movement behavior,particularly optimizing MVPA and ensuring sufficient SP,should be comprehensively and systematically considered in children's educational practice and family education to effectively enhance children's EF.This study not only provided important references for educational practice but also further strengthened the application of embodied cognition theory.
