(1) Background: This study aimed to examine the role of social support in the relationship between perceived motor competence (MC) and physical activity (PA), according to the conceptual model of Motor Development. (2) Methods: Participants were 518 students (46.5% girls), 8-12 years old. By using a structural equation modeling approach, path analysis was used to test the actual-perceived MC relationship and the mediating influence of social support on the perceived MC-PA relationship. Analyses were done with age and sex as covariates. (3) Results: The results showed a good model fit (CFI = 0.98; RMSEA = 0.07; SRMR = 0.02), where actual MC was positively associated with perceived MC (ß = 0.26, < 0.001), which in turn was positively related to social support (ß = 0.34, < 0.001). The model showed the direct social support-PA path (ß = 0.42, < 0.001) and the indirect path from perceived MC through social support to PA (ß = 0.14, < 0.001). (4) Conclusions: This study confirms that social support mediates the perceived MC-PA relationship. As such, it is not only important to build and develop children's actual and perceived MC, but also to promote social support for PA engagement.
(1) 背景：本研究旨在根据运动发展理论的概念模型，检验社会支持在知觉运动能力（MC）与身体活动（PA）之间关系中的作用。(2) 方法：参与者为 518 名 8-12 岁的学生（46.5%为女生）。通过结构方程建模方法，路径分析用于检验实际知觉 MC 与知觉 MC-PA 关系之间的关系以及社会支持的中介作用。分析中考虑了年龄和性别作为协变量。(3) 结果：结果显示模型拟合良好（CFI = 0.98；RMSEA = 0.07；SRMR = 0.02），实际 MC 与知觉 MC 呈正相关（ß = 0.26，<0.001），知觉 MC 又与社会支持呈正相关（ß = 0.34，<0.001）。该模型显示了社会支持-PA 的直接路径（ß = 0.42，<0.001）和通过知觉 MC 到 PA 的间接路径（ß = 0.14，<0.001）。(4) 结论：本研究证实社会支持在知觉 MC-PA 关系中起中介作用。因此，不仅要重视培养和发展儿童的实际和知觉 MC，还要促进社会支持参与 PA。
