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 \u00b1 1.4 years; body mass: 69.6 \u00b1 8.2 kg; stature: 173.5 \u00b1 6.5 cm; federated training experience: 9.7 \u00b1 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%\u20137.54% 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.<\/jats:p>","DOI":"10.3390\/jfmk8010011","type":"journal-article","created":{"date-parts":[[2023,1,19]],"date-time":"2023-01-19T01:33:51Z","timestamp":1674092031000},"page":"11","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Reliability of the Coimbra Reactive Agility Soccer Test (CRAST)"],"prefix":"10.3390","volume":"8","author":[{"given":"Ant\u00f3nio","family":"N\u00f3brega","sequence":"first","affiliation":[{"name":"University of Coimbra, Research Unit for Sport and Physical Activity (CIDAF), Faculty of Sport Sciences and Physical Education, 3040-256 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8681-0642","authenticated-orcid":false,"given":"Hugo","family":"Sarmento","sequence":"additional","affiliation":[{"name":"University of Coimbra, Research Unit for Sport and Physical Activity (CIDAF), Faculty of Sport Sciences and Physical Education, 3040-256 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7922-1540","authenticated-orcid":false,"given":"Vasco","family":"Vaz","sequence":"additional","affiliation":[{"name":"University of Coimbra, Research Unit for Sport and Physical Activity (CIDAF), Faculty of Sport Sciences and Physical Education, 3040-256 Coimbra, Portugal"}]},{"given":"V\u00edtor","family":"Gouveia","sequence":"additional","affiliation":[{"name":"University of Coimbra, Research Unit for Sport and Physical Activity (CIDAF), Faculty of Sport Sciences and Physical Education, 3040-256 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9559-5048","authenticated-orcid":false,"given":"Joel","family":"Barrera","sequence":"additional","affiliation":[{"name":"University of Coimbra, Research Unit for Sport and Physical Activity (CIDAF), Faculty of Sport Sciences and Physical Education, 3040-256 Coimbra, Portugal"}]},{"given":"Andreia","family":"Martins","sequence":"additional","affiliation":[{"name":"University of Coimbra, Research Unit for Sport and Physical Activity (CIDAF), Faculty of Sport Sciences and Physical Education, 3040-256 Coimbra, Portugal"}]},{"given":"Tom\u00e1s","family":"Santos","sequence":"additional","affiliation":[{"name":"University of Coimbra, Research Unit for Sport and Physical Activity (CIDAF), Faculty of Sport Sciences and Physical Education, 3040-256 Coimbra, Portugal"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7536-9780","authenticated-orcid":false,"given":"Jo\u00e3o Pedro","family":"Duarte","sequence":"additional","affiliation":[{"name":"University of Coimbra, Research Unit for Sport and Physical Activity (CIDAF), Faculty of Sport Sciences and Physical Education, 3040-256 Coimbra, Portugal"}]}],"member":"1968","published-online":{"date-parts":[[2023,1,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1418","DOI":"10.1519\/JSC.0000000000000296","article-title":"Validation of the Loughborough Soccer Passing Test in young soccer players","volume":"28","author":"Rue","year":"2014","journal-title":"J.
