This study hypothesized that Chinese\n professional B-boys have a higher injury prevalence than amateurs and the injury characteristics differ in their association with technical movements and training condition. METHODS: A self-developed 27-item questionnaire covering three domains\u2014basic information, training history, and\n injury characteristics\u2014was distributed online to male breakers. Participants were classified into amateur (n=468) and professional (n=178) groups using a composite criterion combining self-assessed skill rank and cumulative training hours. Continuous variables were compared using Mann-Whitney\n U tests, and categorical variables using chi-square tests with Bonferroni correction for post-hoc pairwise comparisons. Generalized estimating equations (GEE) were applied to analyze injury factors while accounting for within-dancer clustering of multiple injuries. RESULTS: Among the 646 dancers,\n 584 (90.4%) reported at least one injury, with no significant difference in injury prevalence between the amateur and professional groups (89.3% vs 93.3%, P=0.445). A total of 1,000 injury cases were documented. The most frequently injured sites were the wrist, knee, shoulder, and waist, with\n shoulder injuries significantly more common in professional dancers (21.3% vs 14.6%, P=0.031). Self-reported contributing factors included insufficient warm-up, fatigue, and perceived deficiencies in basic skills. Over 80% of dancers lacked professional medical support. Exploratory chi-square\n tests revealed that shoulder, knee, and wrist injuries were related with technical movements; however, these patterns were unadjusted for exposure time and therefore reflect only injury distribution, not movement-specific risk. CONCLUSIONS: Injury prevalence was similarly high in amateur and\n professional B-boys, with no significant between-group differences. Commonly injured sites and self-reported contributing factors, together with the lack of medical support, highlight the priorities for prevention. The movement\u2013injury patterns warrant further investigation in future\n prospective studies.<\/jats:p>","DOI":"10.21091\/mppa.2026.03012","type":"journal-article","created":{"date-parts":[[2026,8,28]],"date-time":"2026-08-28T04:31:45Z","timestamp":1787891505000},"page":"130-142","source":"Crossref","is-referenced-by-count":0,"title":["Injury Prevalence and Risk Factors in Professional and Amateur Breakdancers in China: A Cross-Sectional Study"],"prefix":"10.21091","volume":"41","author":[{"given":"Bo","family":"Wang","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"HuiYe","family":"Jia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"XiYang","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lu","family":"Bai","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"8662","container-title":["Medical Problems of Performing Artists"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ingentaconnect.com\/content\/scimed\/mppa\/2026\/00000041\/00000003\/art00004","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T04:30:36Z","timestamp":1788237036000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ingentaconnect.com\/content\/10.21091\/mppa.2026.03012"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,9,1]]},"references-count":0,"journal-issue":{"issue":"3","published-print":{"date-parts":[[2026,9,1]]}},"alternative-id":["0885-1158(20260901)41:3L.130;1-"],"URL":"https:\/\/doi.org\/10.21091\/mppa.2026.03012","relation":{},"ISSN":["0885-1158"],"issn-type":[{"value":"0885-1158","type":"print"}],"subject":[],"published":{"date-parts":[[2026,9,1]]}}}
