Understanding Physical Activity in Children with Varying Body Weights:Impact of Congruence Between Actual and Perceived Motor Competence
Objective:The purpose was to examine the impact of congruence between actual motor competence(MC)and perceived motor competence(PMC)on physical activity(PA)in children with varying body weights.Methods:The Canadian Agility and Movement Skill Assessment,the physical competence subscale of Self-Pere-eption Profile for Children,and the Yamax EX510 pedometer were used to measure MC,PMC,and PA of 342 children(Mage=10.73,SD=0.86)aged 9 to 12 years in Jinan,respectively.Polynomial regression and response surface analysis were conducted to analyze the data.Results:(1)In the congruence situation:children with"high MC-high PMC"had higher PA levels compared to those with"low MC-low PMC"(normal weight:a1=0.50,p＜0.05 and a2=0.09,p＞0.05;overweight and obese:a1=0.59,p＜0.05 and a2=0.01,p＞0.05);(2)in the case of incongruence:normal-weight children with"overestimated MC"showed higher PA levels compared to those with"underestimated MC"(a4=0.07,p＞0.05;a3=-0.19,p＜0.05),but this difference was not significant in overweight and obese children(Z-Hat=0.19,p＜0.05).Conclusion:In the Chinese cultural context,the synergistic improvement of MC and PMC can contribute to the improvement of PA in children with different body weights.However,the impact of incongruent development between MC and PMC on PA varies among children with differ-ent body weights.Targeted strategies are recommended to promote the simultaneous improvement of MC and PMC in children.
