BACKGROUND
Motor competence (MC) is a key component reflecting one's ability to execute motor tasks and is an important predictor of physical fitness. For adolescents, understanding the factors affecting MC is pertinent to their development of more sophisticated sporting skills. Previous studies considered the influence of poor proprioceptive ability on MC, however, the relationship between lower limb joint position sense, kinematic control, and MC is not well understood. Therefore, the aim of this study was to determine the relation between joint position sense and kinematic control with MC in adolescents during a lower limb movement reproduction task.
METHODS
This study was a cross-sectional design. Young people (n = 427, 196 girls and 231 boys) aged 13 to 14 years were recruited. A movement reproduction task was used to assess joint position sense and kinematic control, while the Movement Assessment Battery for Children (mABC-2) was used to assess MC. In this study, participants were categorized into the Typically Developed (TD, n = 231) and Probable Developmental Coordination Disorder (DCD, n = 80) groups for further analysis of joint position sense, kinematic control, and MC between groups.
RESULTS
Kinematic data, specifically normalized jerk, showed a significant correlation with MC. There was no correlation between knee joint position sense and MC, and no group differences between DCD and TD were found.
CONCLUSIONS
Joint position sense should not be used as a measure to distinguish TD and DCD. Rather than joint position sense, control of kinematic movement has a greater influence on the coordination of the lower limbs in adolescents. Movement control training should be implemented in the clinical setting to target kinematic control, rather than focus on joint position sense practice, to improve motor competency.

背景
运动能力（MC）是反映一个人执行运动任务能力的关键组成部分，也是身体健康的重要预测指标。对于青少年来说，了解影响 MC 的因素对于他们发展更复杂的运动技能至关重要。先前的研究考虑了本体感觉能力差对 MC 的影响，但下肢关节位置感、运动学控制与 MC 之间的关系尚不清楚。因此，本研究旨在确定青少年在下肢运动再现任务中关节位置感和运动学控制与 MC 之间的关系。
方法
这是一项横断面设计研究。招募了 13 至 14 岁的青少年（n=427，196 名女孩和 231 名男孩）。使用运动再现任务评估关节位置感和运动学控制，同时使用儿童运动评估 batter（mABC-2）评估 MC。在这项研究中，参与者被分为典型发育（TD，n=231）和可能发展性协调障碍（DCD，n=80）组，以进一步分析组间关节位置感、运动学控制和 MC。
结果
运动学数据，特别是归一化的急动度，与 MC 呈显著相关。膝关节位置感与 MC 无相关性，DCD 与 TD 之间也无组间差异。
结论
关节位置感不应用于区分 TD 和 DCD。运动学运动控制而不是关节位置感对青少年下肢协调性的影响更大。运动控制训练应在临床环境中实施，以针对运动学控制，而不是专注于关节位置感练习，以提高运动能力。
