Data on all injuries that occurred in U-15 youth soccer players during the 2019 season were collected from 681 players of 22 teams through a medical questionnaire. The questionnaire was based on injury surveillance procedures of the Federation International de Football Association Medical and Research Centre and International Olympic Committee, and it comprised questions on demographic characteristics, training conditions, and injury information. Among all players, defenders accounted for 33.0%, followed by attackers (30.7%), midfielders (26.8%), and goalkeepers (7.9%). Most players played soccer on artificial grounds (97.4%). Injuries occurred more frequently during training (56.3%) than during matches (43.7%). Recurrent injury rate was 4.4% and average days to return to full activities were 22.58. The ankle (26.6%) and knee joints (14.1%) were the most common injury locations, and ligament sprains (21.0%), contusions (15.6%), and fractures (13.9%) were the most frequent injury types. In conclusion, Korean youth soccer players have a high injury risk. Therefore, researchers and coaching staff need to consider these results as a key to prevent injuries in youth soccer players and injury prevention programs may help decrease injury rate by providing injury management.<\/jats:p>","DOI":"10.3390\/ijerph17145125","type":"journal-article","created":{"date-parts":[[2020,7,16]],"date-time":"2020-07-16T10:54:46Z","timestamp":1594896886000},"page":"5125","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":21,"title":["Injury Profiles in Korean Youth Soccer"],"prefix":"10.3390","volume":"17","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7680-8546","authenticated-orcid":false,"given":"Inje","family":"Lee","sequence":"first","affiliation":[{"name":"Department of Physical Education, Yonsei University, Seoul 03722, Korea"},{"name":"International Olympic Committee Research Centre KOREA, Yonsei University, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8318-7322","authenticated-orcid":false,"given":"Hee Seong","family":"Jeong","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Yonsei University, Seoul 03722, Korea"},{"name":"International Olympic Committee Research Centre KOREA, Yonsei University, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sae Yong","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Physical Education, Yonsei University, Seoul 03722, Korea"},{"name":"International Olympic Committee Research Centre KOREA, Yonsei University, Seoul 03722, Korea"},{"name":"Institute of Convergence Science, Yonsei University, Seoul 03722, Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,7,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"663","DOI":"10.1016\/S0278-5919(05)70110-1","article-title":"Youth soccer: An epidemiologic perspective","volume":"17","author":"Metzl","year":"1998","journal-title":"Clin.
