Braking and propulsive GRFs were lower and higher, respectively, across the majority of stance phase (6%\u201390% of stance, p&lt;0.01) in unanticipated side-stepping. Vertical GRFs were lower in unanticipated side-stepping in the early stance phase (14%\u201329% of stance, p&lt;0.01).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>Contrary to existing literature, AFLW players exhibited knee joint moments associated with reduced ACL loading when performing unanticipated side-stepping. Players appeared to adopt a \u2018cautious\u2019 approach to the unanticipated side-step (ie, decelerating at the change of direction), by reducing braking and vertical GRFs in the early stance phase of cutting. This approach may be implausible to employ or detrimental to performance during matches. AFLW ACL injury prevention programmes may be enhanced with greater exposure to scenarios that replicate reactive match-play demands when aiming to improve side-stepping biomechanics.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/bmjsem-2023-001587","type":"journal-article","created":{"date-parts":[[2023,6,14]],"date-time":"2023-06-14T13:37:10Z","timestamp":1686749830000},"page":"e001587","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":14,"title":["Anticipatory effects on side-step cutting biomechanics in Women\u2019s Australian Football League players"],"prefix":"10.1136","volume":"9","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-6036-8059","authenticated-orcid":false,"given":"Tess","family":"Rolley","sequence":"first","affiliation":[{"name":"Centre for Sport Research, School of Exercise and Nutrition Sciences, Deakin University, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stephen D","family":"Gill","sequence":"additional","affiliation":[{"name":"Barwon Centre for Orthopaedic Research and Education (B-CORE), Barwon Health, Geelong, Victoria, Australia"},{"name":"School of Medicine, Deakin University, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Meghan","family":"Keast","sequence":"additional","affiliation":[{"name":"Centre for Sport Research, School of Exercise and Nutrition Sciences, Deakin University, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tom","family":"Reade","sequence":"additional","affiliation":[{"name":"School of Medicine, Deakin University, Geelong, Victoria, Australia"},{"name":"Emergency Department, University Hospital Geelong, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Richard","family":"Page","sequence":"additional","affiliation":[{"name":"Barwon Centre for Orthopaedic Research and Education (B-CORE), Barwon Health, Geelong, Victoria, Australia"},{"name":"School of Medicine, Deakin University, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jason","family":"Bonacci","sequence":"additional","affiliation":[{"name":"Centre for Sport Research, School of Exercise and Nutrition Sciences, Deakin University, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julian","family":"Stella","sequence":"additional","affiliation":[{"name":"School of Medicine, Deakin University, Geelong, Victoria, Australia"},{"name":"Emergency Department, University Hospital Geelong, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brett","family":"Johnson","sequence":"additional","affiliation":[{"name":"Geelong Cats Football Club, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5639-6388","authenticated-orcid":false,"given":"Aaron","family":"Fox","sequence":"additional","affiliation":[{"name":"Centre for Sport Research, School of Exercise and Nutrition Sciences, Deakin University, Geelong, Victoria, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"239","published-online":{"date-parts":[[2023,6,14]]},"reference":[{"key":"2025083112271274000_9.2.e001587.1","doi-asserted-by":"publisher","DOI":"10.1016\/j.ocl.2006.09.001"},{"key":"2025083112271274000_9.2.e001587.2","doi-asserted-by":"crossref","unstructured":"Doorley JD , Womble MN .
