摘要
背景：运动能力（MC）是反映一个人执行运动任务能力的关键要素，也是预测体能的重要指标。对于青少年来说，了解影响 MC 的因素对他们发展更复杂的运动技能至关重要。以往的研究考虑了本体感觉能力差对 MC 的影响，但对下肢关节位置感、运动控制和 MC 之间的关系还不甚了解。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控制与 MC 之间的关系：本研究采用横断面设计。招募了 13 至 14 岁的青少年（n = 427，196 名女孩和 231 名男孩）。运动再现任务用于评估关节位置感和运动控制能力，而儿童运动评估电池（mABC-2）则用于评估运动控制能力。在这项研究中，参与者被分为典型发育（TD，n = 231）组和可能发育协调障碍（DCD，n = 80）组，以便进一步分析组间的关节位置感、运动控制和运动控制能力：运动学数据，特别是归一化挺举，与 MC 有显著相关性。膝关节位置感与 MC 之间没有相关性，也没有发现 DCD 和 TD 的组间差异：结论：关节位置感不应作为区分 TD 和 DCD 的标准。与关节位置感相比，运动控制对青少年下肢协调能力的影响更大。在临床环境中应针对运动控制进行训练，而不是专注于关节位置感的练习，以提高运动能力：NCT03150784.注册时间：2017年5月12日，https://clinicaltrials.gov/study/NCT03150784 。
Knee joint position sense and kinematic control in relation to motor competency in 13 to 14-year-old adolescents.
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.
