This study examined the effects of perceptions of motor abilities on aerobic and musculoskeletal exercise performance in young children at risk for developmental coordination disorder (rDCD). The participants (N = 539) were part of a larger cohort study, the Coordination and Activity Tracking in Children (CATCH) study. The Movement Assessment Battery for Children (2nd Edition) was used to determine rDCD children. Perceptions of motor abilities were measured by the Perceived Efficacy and Goals Setting system. Aerobic exercise performance was measured using the Bruce Protocol treadmill test, and musculoskeletal exercise performance was assessed using the standing long jump and the Wingate Anaerobic test. The rDCD children reported lower Perceived Efficacy and Goals Setting scores and performed worse on all exercise performance measures. Perceptions of ability also mediated the relationship between developmental coordination disorder and each exercise performance test. It is concerning that children with low motor coordination report lower perceptions of ability even at a very young age.

本研究探讨了运动能力认知对有发育协调障碍 (rDCD) 风险的幼儿有氧运动和肌肉骨骼运动表现的影响。参与者 ( N  = 539) 是一项更大的队列研究——儿童协调和活动跟踪 (CATCH) 研究的一部分。儿童运动评估套组（第二版）用于确定 rDCD 儿童。对运动能力的感知是通过感知效能和目标设定系统来测量的。使用布鲁斯协议跑步机测试测量有氧运动表现，并使用立定跳远和温盖特无氧测试评估肌肉骨骼运动表现。rDCD 儿童的感知功效和目标设定分数较低，并且在所有运动表现指标上表现较差。对能力的看法也调节了发育协调障碍与每次运动表现测试之间的关系。令人担忧的是，运动协调能力低下的儿童即使在很小的时候就对能力的感知也较低。
