Posttournament follow-up was made for all injuries. Match exposure for each player was recorded through video review to examine individual risk factors.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>A total of 58 injuries were recorded during 54 matches. The overall injury rate was 179.0 (95% CI, 138.4-231.6), and the time-loss injury rate was 28.2 (95% CI, 14.7-54.1) per 1000 player-hours. The foot\/toe (34.9%) was the most frequently injured area, followed by the lower leg (22.2%) and thigh (11.1%). There was only 1 ankle injury (1.6%). The most frequent injury type was contusions (60.3%), followed by lacerations\/abrasions (14.3%) and sprains\/ligament injuries (6.3%). Only 4 injuries resulted in \u226530 days of time-loss (7.4%). After adjusting for age, a previous history of severe injury and longer experience of beach soccer were significantly associated with injury risk.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>The time-loss injury rate in this study was comparable to the rates reported during the matches of soccer or futsal tournaments. However, a greater incidence of foot\/toe injury and lacerations\/abrasions as well as a lower incidence of ankle injury distinguished beach soccer from soccer and futsal, possibly related to the specific playing conditions of being barefoot on a sand surface.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1177\/2325967115625636","type":"journal-article","created":{"date-parts":[[2016,1,29]],"date-time":"2016-01-29T23:13:13Z","timestamp":1454109193000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":18,"title":["Beach Soccer Injuries During the Japanese National Championships"],"prefix":"10.1177","volume":"4","author":[{"given":"Tomoyuki","family":"Shimakawa","sequence":"first","affiliation":[{"name":"Department of Orthopaedic Surgery, Urasoe General Hospital, Okinawa, Japan."},{"name":"Department of Orthopaedic Surgery, Rokuto Orthopaedic Clinic, Okinawa, Japan."},{"name":"Department of Sports Orthopaedic Surgery, Aspetar Orthopaedic and Sports Medicine Hospital, Doha, Qatar."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Shimakawa","sequence":"additional","affiliation":[{"name":"Unit\u00e9 d\u2019\u00c9pid\u00e9miologie des Maladies \u00c9mergentes, Institut Pasteur, Paris, France."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoko","family":"Kawasoe","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Urasoe General Hospital, Okinawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kouji","family":"Yoshimura","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Rokuto Orthopaedic Clinic, Okinawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuma","family":"Chinen","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Rokuto Orthopaedic Clinic, Okinawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kazuya","family":"Eimon","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Rokuto Orthopaedic Clinic, Okinawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wataru","family":"Chibana","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Rokuto Orthopaedic Clinic, Okinawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shinichi","family":"Shirota","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Urasoe General Hospital, Okinawa, Japan."},{"name":"Department of Orthopaedic Surgery, Rokuto Orthopaedic Clinic, Okinawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kei","family":"Kadekawa","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Rokuto Orthopaedic Clinic, Okinawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roald","family":"Bahr","sequence":"additional","affiliation":[{"name":"Department of Sports Medicine, Oslo Sports Trauma Research Center, Norwegian School of Sport Sciences, Oslo, Norway."},{"name":"Department of Sports Injury and Illness Prevention, Orthopaedic Surgery, Aspetar Orthopaedic and Sports Medicine Hospital, Doha, Qatar."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomomi","family":"Uezato","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Rokuto Orthopaedic Clinic, Okinawa, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroshi","family":"Ikeda","sequence":"additional","affiliation":[{"name":"Department of Orthopaedic Surgery, Juntendo University, Tokyo, Japan."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2016,1,29]]},"reference":[{"key":"bibr1-2325967115625636","doi-asserted-by":"publisher","DOI":"10.1136\/bjsports-2011-090852"},{"key":"bibr2-2325967115625636","doi-asserted-by":"publisher","DOI":"10.3113\/FAI.2008.0919"},{"key":"bibr3-2325967115625636","doi-asserted-by":"publisher","DOI":"10.1177\/03635465030310010401"},{"key":"bibr4-2325967115625636","doi-asserted-by":"publisher","DOI":"10.1177\/28.suppl_5.s-3"},{"key":"bibr5-2325967115625636","doi-asserted-by":"publisher","DOI":"10.1177\/28.suppl_5.s-69"},{"key":"bibr6-2325967115625636","doi-asserted-by":"publisher","DOI":"10.1177\/0363546506288018"},{"key":"bibr7-2325967115625636","unstructured":"FIFA.
