The purpose of this prospective cohort study was to investigate the frequency, incidence, and pattern of time\u2010loss injuries in an elite male football academy, exploring injuries in relation to age and maturation status. Across four consecutive playing seasons, playing exposure and injuries to all academy players (U\u20199 to U\u201921) were recorded by club medical staff. Maturation status at the time of injury was also calculated for players competing in U\u201913 to U\u201916 aged squads. Time\u2010loss injury occurrence and maturation status at time of injury were the main outcome measures. A total of 603 time\u2010loss injuries were recorded, from 190 different players. Playing exposure was 229\u00a0317\u00a0hours resulting in an overall injury rate of 2.4 p\/1000\u00a0h, ranging from 0.7 p\/1000\u00a0h (U\u201911) to 4.8 p\/1000\u00a0h (U\u201921). Most injuries were traumatic in mechanism (73%). The most common injury location was the thigh (23%), and the most common injury type was muscle injury (29%) combining to provide the most common injury diagnosis; thigh muscle injury (17%). In U\u201913\u2010U\u201916 players, a higher number of injuries to early\u2010maturing players were observed in U\u201913\u2010U\u201914 players, while more injuries to U\u201915\u2010U\u201916 players occurred when classed as \u201con\u2010time\u201d in maturity status. Maturation status did not statistically relate to injury pattern; however, knee bone (not\u2010fracture) injuries peaked in U\u201913 players while hip\/groin muscle injuries peaked in U\u201915 players.<\/jats:p>","DOI":"10.1111\/sms.13933","type":"journal-article","created":{"date-parts":[[2021,2,10]],"date-time":"2021-02-10T06:17:32Z","timestamp":1612937852000},"page":"1324-1334","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":50,"title":["Injuries in youth football and the relationship to player maturation: An analysis of time\u2010loss injuries during four seasons in an English elite male football academy"],"prefix":"10.1111","volume":"31","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8787-7275","authenticated-orcid":false,"given":"Neil","family":"Light","sequence":"first","affiliation":[{"name":"Department of Sport and Exercise Sciences University of Chichester  Chichester UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Adam","family":"Johnson","sequence":"additional","affiliation":[{"name":"Brighton and Hove Albion Football Club  Brighton UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stuart","family":"Williams","sequence":"additional","affiliation":[{"name":"Brighton and Hove Albion Football Club  Brighton UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Neal","family":"Smith","sequence":"additional","affiliation":[{"name":"Department of Sport and Exercise Sciences University of Chichester  Chichester UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Beverley","family":"Hale","sequence":"additional","affiliation":[{"name":"Department of Sport and Exercise Sciences University of Chichester  Chichester UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kristian","family":"Thorborg","sequence":"additional","affiliation":[{"name":"Department of Orthopedic Surgery Sports Orthopedic Research Center Copenhagen (SORC\u2010C) Copenhagen University Hospital Amager\u2010Hvidovre  Copenhagen Denmark"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,3,5]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s40279-013-0061-x"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.1080\/02640414.2017.1402535"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1080\/24733938.2017.1410564"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1177\/0363546505283271"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1123\/pes.2017-0240"},{"key":"e_1_2_6_7_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0838.2006.00594.x"},{"issue":"4","key":"e_1_2_6_8_1","first-page":"351","article-title":"Sport injuries aligned to peak height velocity in talented pubertal soccer players","volume":"35","author":"Sluis A","year":"2014","journal-title":"Int J Sports Med"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2017-097626"},{"key":"e_1_2_6_10_1","doi-asserted-by":"publisher","DOI":"10.1136\/bmjsem-2016-000132"},{"key":"e_1_2_6_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.jsams.2020.08.004"},{"key":"e_1_2_6_12_1","unstructured":"The Premier League.Elite player performance plan.2011.
