The main goals of this study were to identify profiles in school-aged children based on actual Motor Competence (MC) and accuracy of Perceived Motor Competence (PMC) and to examine how children with different profiles differ in terms of Physical Fitness (PF) and Body Fat percentage (BF%). The MC of a total of 287 children (51.6% boys, aged between 6 and 10 years-old) was assessed using the Motor Competence Assessment (MCA) instrument, and the accuracy of the PMC was measured using motor tasks (standing long jump, throwing, kicking, and walking backwards). PF and BF% were assessed using the 20m shuttle run test and TANITA, respectively. Cluster (C) analysis revealed four profiles, two of which were aligned - high MC-accurate PMC (C4) and low-inaccurate (C2), and two that were non-aligned - high-inaccurate (C1) and low-accurate (C3). Children in C4 performed better on PF and had less BF% than children in C3 and C2.
本研究的主要目的是根据实际运动能力（MC）和感知运动能力（PMC）的准确性来确定学龄儿童的特征，并探讨具有不同特征的儿童在身体适应性（PF）和体脂百分比（BF%）方面的差异。共有 287 名儿童（51.6%为男生，年龄在 6 至 10 岁之间）的 MC 使用运动能力评估（MCA）工具进行评估，PMC 的准确性使用运动任务（站立跳远、投掷、踢腿和向后走）进行测量。PF 和 BF%使用 20 米穿梭跑测试和 TANITA 分别进行评估。聚类（C）分析显示了四个特征，其中两个特征是一致的——高 MC-准确 PMC（C4）和低不准确（C2），两个特征是不一致的——高不准确（C1）和低准确（C3）。与 C3 和 C2 相比，C4 组的儿童在 PF 方面表现更好，BF%更低。
