BACKGROUND/PURPOSE: Movement ability is an often-overlooked component of sports science and sports medicine research and needs to be considered alongside the appraisal of physical fitness and performance characteristics. To achieve this, a standardised assessment tool is required. The purpose of this paper is to introduce a new method for assessing movement ability and present results for intra- and inter-rater reliability.
National level female football players (n=17) were assessed using a novel movement assessment tool, the Athletic Ability Assessment (AAA). Athletes were assessed according to the scoring criteria by the primary researcher in real-time and via video on two separate occasions to estimate intra-tester reliability. Inter-tester reliability was estimated using the difference between five other testers' video-based scores.
The intra-tester minimal detectable change (MDC) for the composite AAA score was 2.9 points (90% confidence limits; 2.3 - 4.2 points) (2.5%; 2.0 - 3.6%) with an intraclass correlation coefficient (ICC) of 0.97 (0.92 - 0.99). Inter-tester MDC for the composite AAA score was 2.8 points (2.5 - 3.3 points) (2.4%; 2.1 - 2.8%) with an ICC 0.96 (0.94 - 0.98) Individual exercise scores for the intra- and inter-tester show a similar range MDC of between 0.4 - 1.1 points and kappa statistic level of agreement between 0.32 -0.77.
Results of the reliability analysis suggest high levels of agreement between scorers for total scores and provide reference values for minimal detectable changes using the AAA. The aim of the AAA is to become a reliable movement assessment protocol that addresses specific sporting populations. The reliability of AAA scoring established in this study is the first step in supporting the utilization of the AAA in future research.

背景/目的：运动能力是体育科学和运动医学研究中一个经常被忽视的组成部分，需要与身体素质和运动表现特征的评估一起加以考虑。要做到这一点，就需要一种标准化的评估工具。本文的目的是介绍一种评估运动能力的新方法，并展示评分者内和评分者间信度的结果。
使用一种新颖的运动评估工具——运动能力评估（AAA）对国家级女子足球运动员（n = 17）进行评估。主要研究人员根据评分标准在两个不同的场合对运动员进行实时评估，并通过视频评估，以估计测试者内信度。使用其他五名测试者基于视频的分数之间的差异来估计测试者间信度。
AAA综合得分的测试者内最小可检测变化（MDC）为2.9分（90%置信区间；2.3 - 4.2分）（2.5%；2.0 - 3.6%），组内相关系数（ICC）为0.97（0.92 - 0.99）。AAA综合得分的测试者间MDC为2.8分（2.5 - 3.3分）（2.4%；2.1 - 2.8%），ICC为0.96（0.94 - 0.98）。测试者内和测试者间的单项运动得分显示出相似的MDC范围，在0.4 - 1.1分之间，kappa统计一致性水平在0.32 - 0.77之间。
信度分析结果表明，评分者在总分上的一致性程度较高，并提供了使用AAA时最小可检测变化的参考值。AAA的目标是成为一种适用于特定运动人群的可靠运动评估方案。本研究中建立的AAA评分信度是支持在未来研究中使用AAA的第一步。
