Fifteen professional male academy players participated in three training sessions, completing standardised contact\u2010drills while wearing custom\u2010fitted iMGs, all sessions were filmed. HAE data (peak linear acceleration and peak angular acceleration) were captured, synchronised, and processed alongside video data. Binomial logistic regression and ordinal mixed\u2010effect regression models were used to calculate overall and exceedance probabilities. Data included 1402 (93\u00a0\u00b1\u00a050 per player) contact\u2010drill observations, of which 133 had HAEs \u2265\u00a05\u00a0\n                    <jats:italic>g<\/jats:italic>\n                    (9\u00a0\u00b1\u00a08 per player). Substantial variability in probability for HAEs \u2265\u00a05\u00a0\n                    <jats:italic>g<\/jats:italic>\n                    (1.3%\u201341.3%) was observed across drills. Standing wrestle had the highest HAE \u2265\u00a05\u00a0\n                    <jats:italic>g<\/jats:italic>\n                    probability (41.3%; CI: 31.0%\u201352.3%), while tackle shield hits at 1\u00a0m had the lowest (1.3%; CI: 0.5%\u20133.4%). HAE probability was greater for tacklers than ball\u2010carriers. Overall, probability of a HAE \u2265\u00a025\u00a0\n                    <jats:italic>g<\/jats:italic>\n                    was &lt;\u00a01.1%. Standardised contact\u2010drills varied in HAE probabilities, but chances of higher magnitude HAEs was low for all drills. Overall, the probability of a HAE during standardised contact\u2010drills was low, although practitioners should consider the differences (i.e., the variability) in HAE probabilities when managing HAE training exposure.\n                  <\/jats:p>","DOI":"10.1002\/ejsc.70232","type":"journal-article","created":{"date-parts":[[2026,8,8]],"date-time":"2026-08-08T19:04:45Z","timestamp":1786215885000},"source":"Crossref","is-referenced-by-count":0,"title":["Head Acceleration Event Probabilities During Standardised Contact Drills in Academy Men's Rugby League"],"prefix":"10.1002","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-3656-8450","authenticated-orcid":false,"given":"Ryan","family":"White","sequence":"first","affiliation":[{"name":"Carnegie Applied Rugby Research (CARR) Centre Carnegie School of Sport Leeds Beckett University  Leeds UK"},{"name":"Sport Science and Medicine Department Crystal Palace FC  London UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Weaving","sequence":"additional","affiliation":[{"name":"Carnegie Applied Rugby Research (CARR) Centre Carnegie School of Sport Leeds Beckett University  Leeds UK"},{"name":"Department of Physical Activity and Sport Faculty of Arts and Sciences Edge Hill University  Ormskirk UK"},{"name":"Applied Sports Science and Exercise Testing Laboratory The University of Newcastle  Ourimbah New South Wales Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6518-1389","authenticated-orcid":false,"given":"Cameron","family":"Owen","sequence":"additional","affiliation":[{"name":"Carnegie Applied Rugby Research (CARR) Centre Carnegie School of Sport Leeds Beckett University  Leeds UK"},{"name":"Rugby Football League  Manchester UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1428-9282","authenticated-orcid":false,"given":"Greg","family":"Roe","sequence":"additional","affiliation":[{"name":"Carnegie Applied Rugby Research (CARR) Centre Carnegie School of Sport Leeds Beckett University  Leeds UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4243-132X","authenticated-orcid":false,"given":"Thomas","family":"Sawczuk","sequence":"additional","affiliation":[{"name":"Carnegie Applied Rugby Research (CARR) Centre Carnegie School of Sport Leeds Beckett University  Leeds UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5398-4416","authenticated-orcid":false,"given":"James","family":"Tooby","sequence":"additional","affiliation":[{"name":"Carnegie Applied Rugby Research (CARR) Centre Carnegie School of Sport Leeds Beckett University  Leeds UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Gemma","family":"Phillips","sequence":"additional","affiliation":[{"name":"Carnegie Applied Rugby Research (CARR) Centre Carnegie School of Sport Leeds Beckett University  Leeds UK"},{"name":"Rugby Football League  Manchester UK"},{"name":"Uni\u2010X Mobility Cycling  Oslo Norway"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dane","family":"Vishnubala","sequence":"additional","affiliation":[{"name":"Rugby Football League  Manchester UK"},{"name":"Faculty of Biological Sciences School of Biomedical Sciences University of Leeds  Leeds UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Anderson","sequence":"additional","affiliation":[{"name":"Rugby Football League  Manchester UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4274-6236","authenticated-orcid":false,"given":"Ben","family":"Jones","sequence":"additional","affiliation":[{"name":"Carnegie Applied Rugby Research (CARR) Centre Carnegie School of Sport Leeds Beckett University  Leeds UK"},{"name":"Rugby Football League  Manchester UK"},{"name":"PREM Rugby  London UK"},{"name":"School of Behavioural and Health Sciences Faculty of Health Sciences Australian Catholic University  Brisbane Queensland Australia"},{"name":"Division of Exercise Science and Sports Medicine Department of Human Biology Faculty of Health Sciences the University of Cape Town and the Sports Science Institute of South Africa  Cape Town South Africa"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,8]]},"reference":[{"key":"e_1_2_12_2_1","unstructured":"Christensen R.
