Background: ACL injuries present a considerable burden in female football, with highest incidence being related to change of direction (COD) tasks. The aim was to identify if differences existed between an anticipated and unanticipated 90-degree cutting task using the CMAS. Methods: 11 female professional footballers completed twelve 90-degree COD tasks (6 anticipated, 6 unanticipated). Participants performed the unanticipated task in response to a moving football at the start of their acceleration. All COD tasks were filmed and assessed using the CMAS. Results: The CMAS score for the unanticipated COD task (5.53 ± 0.71) was significantly larger than for the anticipated COD task (3.55 ± 0.85, p < 0.012). Excellent intra-rater reliability was observed (ICC = 0.97) for analysis of CMAS scores. Conclusions: Female footballers in this sample demonstrated a greater CMAS score during an unanticipated COD task compared to an anticipated COD task. These athletes are therefore more likely to display ‘high-risk’ movement patterns, thus greater risk of injury. Reacting to a sporting implement, such as a moving ball, may be a contributing factor to these results. Further research into unanticipated COD tasks should be considered to determine why these differences occur and the impact of anticipation on performance.
前交叉韧带损伤在女子足球运动中造成了相当大的负担，其中最高发病率与变向（COD）任务有关。目的是使用CMAS确定预期和非预期的90度切入任务之间是否存在差异。方法：11名女子职业足球运动员完成了12次90度COD任务（6次预期，6次非预期）。参与者在加速开始时对移动的足球做出反应来执行非预期任务。所有COD任务均被拍摄并使用CMAS进行评估。结果：非预期COD任务的CMAS评分（5.53±0.71）显著高于预期COD任务（3.55±0.85，p<0.012）。CMAS评分分析显示出极好的评分者内信度（ICC=0.97）。结论：与预期COD任务相比，该样本中的女子足球运动员在非预期COD任务期间表现出更高的CMAS评分。因此，这些运动员更有可能表现出“高风险”的运动模式，从而受伤风险更高。对运动器具（如移动的球）做出反应可能是导致这些结果的一个因素。应考虑对非预期COD任务进行进一步研究，以确定这些差异产生的原因以及预期对表现的影响。
