(1) Background: The developmental model describes possible mechanisms that could impact the trajectory of children and adolescents' health behaviors related to obesity; however, few data are available that support this model in the adolescent population. This study investigated the associations among motor competence (MC), moderate-to-vigorous physical activity (MVPA), perceived motor competence (PMC), and aerobic fitness in children and adolescents and the mediating and moderating effects of PMC, aerobic fitness, and weight status on the MC-MVPA relationship. (2) Methods: Participants included 47 adolescents (12.2 ± 1.6 y; 55% male) who completed the Bruininks-Oseretsky Test of Motor Proficiency, 2nd Edition (MC), Harter's perceived self-competency questionnaire (PMC), and the PACER test (aerobic fitness) and whose MVPA was measured via accelerometry. The body mass index (BMI) was calculated from measured height and weight. (3) Results: There were positive correlations between MC and fitness [(47) = 0.469, < 0.01], PMC and fitness [(47) = 0.682, < 0.01], and PMC and MC [(47) = 0.416, < 0.01]. There were no associations among MVPA and MC, PMC, or fitness ( > 0.05). There were inverse associations between BMI and both MVPA [(44) = -0.410, < 0.01] and fitness [(47) = 0.295, < 0.05]. The association between MC and MVPA was mediated by fitness (β = 0.3984; 95% CI (0.0564-0.7985)). (4) Conclusions: The associations among MC, PMC, and fitness highlight the critical role of MC in health and partially support the proposed developmental model concerning the relationships that exist among MC, MVPA, PMC, fitness, and BMI.
(1) 背景：发育模型描述了可能影响儿童和青少年与肥胖相关健康行为轨迹的机制；然而，在青少年群体中，支持该模型的数据很少。本研究调查了儿童和青少年的运动能力（MC）、中度至剧烈身体活动（MVPA）、感知运动能力（PMC）和有氧适能之间的关联，以及PMC、有氧适能和体重状况对MC-MVPA关系的中介和调节作用。(2) 方法：参与者包括47名青少年（12.2±1.6岁；55%为男性），他们完成了第二版布鲁宁克斯-奥塞瑞斯基运动熟练度测试（MC）、哈特感知自我能力问卷（PMC）和波比跳测试（有氧适能），其MVPA通过加速度计测量。根据测量的身高和体重计算体重指数（BMI）。(3) 结果：MC与适能之间存在正相关[r(47)=0.469，P<0.01]，PMC与适能之间存在正相关[r(47)=0.682，P<0.01]，PMC与MC之间存在正相关[r(47)=0.416，P<0.01]。MVPA与MC、PMC或适能之间无关联（P>0.05）。BMI与MVPA[r(44)=-0.410，P<0.01]和适能[r(47)=-0.295，P<0.05]之间均存在负相关。MC与MVPA之间的关联由适能介导（β=0.3984；95%CI(0.0564 - 0.7985)）。(4) 结论：MC、PMC和适能之间的关联突出了MC在健康中的关键作用，并部分支持了所提出的关于MC、MVPA、PMC、适能和BMI之间关系的发育模型。
