Abstract

Understanding the mechanisms associated with engaging in physical activity (PA) is crucial for its promotion. The aim was to analyze the relationship between motor competence (MC) and PA and the role of physical fitness (PF). Participants were N = 1,064 children of both sexes (n = 530 girls) and 7.87 ± 1.17 years of age. MC was assessed with KörperkoordinationTest für Kinder. PF was assessed with 50-yard dash, 1-mile run/walk, and standing long jump. PA was assessed with a questionnaire. Mediation and moderation were determined according to Baron and Kenny using Sobel test for indirect effect and using PROCESS (version 3.4). Mediation results showed perfect mediation in girls but not in boys and not when all participants were included in the analysis. The linear moderation was significant for all participants and for boys and girls apart. However, the results of conditional effects of MC at the 16th, 50th, and 84th percentile of the PF, which became significant at the 50th percentile for all participants and for boys, were not significant in girls. In conclusion, perfect mediation seems to exist in girls but not in boys. In boys, the relationship between MC and PA seems conditioned by the PF levels.

体适能在运动能力与身体活动关系中的作用:中介还是调节?

了解参与体育活动(PA)的相关机制对于促进其发展至关重要。目的是分析运动能力(MC)和运动能力(PA)之间的关系以及身体素质(PF)的作用。研究对象为1064名男女儿童(530名女孩)，年龄为7.87±1.17岁。用KörperkoordinationTest f r Kinder评估MC。对PF进行了50码短跑、1英里跑/走和立定跳远的评估。通过问卷评估PA。根据Baron和Kenny使用Sobel间接效应检验和PROCESS(3.4版)来确定中介和适度。调解结果显示，在女孩中有完美的调解，而在男孩中没有，当所有参与者都包括在分析中时也没有。线性调节对所有参与者都是显著的，除了男孩和女孩。然而，MC的条件效应在PF的第16、50和84百分位的结果，在所有参与者和男孩的第50百分位变得显著，在女孩中不显著。综上所述，完美的调解似乎存在于女孩身上，而不存在于男孩身上。在男孩中，MC和PA之间的关系似乎受PF水平的制约。
