This study investigated relationships between fall characteristics and high\u2010risk falls at jumps in cross\u2010country eventing. A video analysis protocol was systematically developed to analyze 87 video recordings of high\u2010risk rider falls; defined as when the rider's head impacted the ground and\/or where there was potential horse impact with the rider. Falls were classified according to competition type, jump type, horse\u2010related, and rider\u2010related factors. At least one high\u2010risk fall characteristic was observed in 45 of 87 examined falls. Multivariable best subsets regression identified five independent variables explaining 38.4% of the variance in the number of high\u2010risk falls. Increased likelihood of high\u2010risk falls was associated with continuation of horse direction or speed upon rider ground impact, higher jump approach speed, changes in rider body posture upon landing, rider air jacket usage, and reduced rider fall time. The Eventing Fall Assessment Instrument (EFAI) video analysis protocol (attached as <jats:ext-link xmlns:xlink=\"http:\/\/www.w3.org\/1999\/xlink\" xlink:href=\"#sms14037-sup-0001\">supplementary material<\/jats:ext-link>) facilitated systematic examination of multiple characteristics associated with high\u2010risk falls and identified likely influential characteristics. Based on EFAI and subsequent data analyses, findings suggest optimized approach speed for correct striding and take\u2010off; jump design to enable run\u2010out; and rider training could help reduce the occurrence of high\u2010risk falls. Air jacket usage and their design characteristics warrant further investigation.<\/jats:p>","DOI":"10.1111\/sms.14037","type":"journal-article","created":{"date-parts":[[2021,8,23]],"date-time":"2021-08-23T08:26:25Z","timestamp":1629707185000},"page":"2187-2197","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Development of a video analysis protocol and assessment of fall characteristics in equestrian cross\u2010country eventing"],"prefix":"10.1111","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5175-3841","authenticated-orcid":false,"given":"Lindsay E.","family":"Nylund","sequence":"first","affiliation":[{"name":"School of Health Sciences Discipline of Exercise and Sports Science The University of Sydney Sydney NSW Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peter J.","family":"Sinclair","sequence":"additional","affiliation":[{"name":"School of Health Sciences Discipline of Exercise and Sports Science The University of Sydney Sydney NSW Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew N.","family":"McLean","sequence":"additional","affiliation":[{"name":"Equitation Science International Tuerong Vic Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6099-392X","authenticated-orcid":false,"given":"Stephen","family":"Cobley","sequence":"additional","affiliation":[{"name":"School of Health Sciences Discipline of Exercise and Sports Science The University of Sydney Sydney NSW Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2021,9]]},"reference":[{"key":"e_1_2_11_2_1","doi-asserted-by":"publisher","DOI":"10.1249\/jsr.0000000000000674"},{"key":"e_1_2_11_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10140\u2010019\u201001718\u20108"},{"key":"e_1_2_11_4_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.puhe.2018.11.023"},{"key":"e_1_2_11_5_1","unstructured":"F\u00e9d\u00e9ration Equeste Internationale..FEI Eventing Risk Management Program Statistics 2008\u20102019.
