BACKGROUND/OBJECTIVE: The directional relationship between physical literacy (PL) and physical activity (PA) in children remains unclear. This study explored the directionality of the relationship between children's actual PL and PA, and whether their PL perceptions mediate this relationship.
This was a cross-sectional study. In total, 371 children (153 boys; M = 10.0 ± 1.0) from Chinese primary schools were recruited to complete all the assessments. Structural equation modeling (SEM) was conducted to determine a reciprocal relationship between Motivation and Confidence, Daily Behavior and moderate-to vigorous-intensity physical activity (MVPA).
When perceived PL was examined as a mediator, the model with direction from MVPA to actual PL was observed with significance in Motivation and Confidence ( = 0.48) and Daily Behavior ( = 0.20). Perceived PL displayed no mediation effect for the direction from actual PL to MVPA.
This study provides evidence that engagement in PA might be useful to support the continuous development of PL. As perceived PL is an integral part of this relationship, future research is needed to understand its role for providing potential intervention targets to improve these outcomes among Chinese children.
背景/目的：儿童身体素质（PL）与身体活动（PA）之间的方向性关联尚不清楚。本研究探讨了儿童实际PL与PA之间关系的方向性，以及他们对PL的认知是否介导了这种关系。
这是一项横断面研究。总共招募了371名来自中国小学的儿童（153名男孩；平均年龄M = 10.0 ± 1.0岁）来完成所有评估。采用结构方程模型（SEM）来确定动机与信心、日常行为与中等至剧烈强度身体活动（MVPA）之间的相互关系。
当将感知到的PL作为中介变量进行检验时，观察到从MVPA到实际PL方向的模型在动机与信心（β = 0.48）和日常行为（β = 0.20）方面具有显著性。感知到的PL对从实际PL到MVPA的方向没有中介作用。
本研究提供了证据，表明参与PA可能有助于支持PL的持续发展。由于感知到的PL是这种关系的一个组成部分，未来需要开展研究以了解其在为改善中国儿童这些结果提供潜在干预靶点方面的作用。
