Agility is a fitness-skill-related component that should be a part of the standard physiological testing for soccer players and one of the key performance indicators in soccer. The present study aimed to assess the reliability of the CRAST as a research tool in the study of soccer skills. Twenty-one university soccer players (chronological age: 19.3 ± 1.4 years; body mass: 69.6 ± 8.2 kg; stature: 173.5 ± 6.5 cm; federated training experience: 9.7 ± 3.6 years) volunteered for the testing protocol. The CRAST requires players to complete random courses six times as quickly as possible. In addition, the CRAST requires players to control and dribble the markers (four different colors: green, yellow, blue, and red). The soccer players completed three trials, each separated by one week. The first trial accounted for familiarization; the second and third were considered for analysis. The correlation for overall performance was very strong. The reliability of the CRAST was slightly better for total time than that for the penalty score (0.95 vs. 0.93). The TEM and the associated CV range of 7.04%-7.54% were for the penalty score and the total time, respectively. For both measurements, the ICC values also represent excellent reliability, as both values were over 0.900. The CRAST is a reliable protocol for assessing agility in soccer players.
敏捷性是一项与健身技能相关的要素，应成为足球运动员标准生理测试的一部分，也是足球运动中的关键性能指标之一。本研究旨在评估CRAST作为研究足球技能的一种工具的可靠性。21名大学足球运动员（实际年龄：19.3±1.4岁；体重：69.6±8.2千克；身高：173.5±6.5厘米；参加联合会训练的经验：9.7±3.6年）自愿参与测试方案。CRAST要求运动员尽可能快地六次完成随机路线。此外，CRAST要求运动员控制并带球绕过标志物（四种不同颜色：绿色、黄色、蓝色和红色）。足球运动员完成了三次测试，每次测试间隔一周。第一次测试用于熟悉；第二次和第三次测试用于分析。整体表现的相关性非常强。CRAST在总时间方面的可靠性略优于罚球得分方面的可靠性（0.95对0.93）。罚球得分和总时间的TEM及相关CV范围分别为7.04% - 7.54%。对于这两项测量，ICC值也都代表了极好的可靠性，因为两个值都超过了0.900。CRAST是评估足球运动员敏捷性的一项可靠方案。
