Zumba is a highly popular Latin-inspired dance fitness program with ∼14 million participants in 150 countries. However, there is little published data on the rates or types of injuries among participants. We surveyed a convenience sample of 49 adults (100% participation) in 5 Zumba classes in Hawai'i. Participants described any prior Zumba-related injuries. We used t-tests and logistic regression to determine if participant demographics or intensity of Zumba classes were associated with injuries. Participants were mostly female (82%), averaged 43.9 years of age (range 19 to 69 years), and took an average of 3 classes/week (1-2 hours/class) for an average of 11 months. Fourteen participants (29%) reported 21 prior Zumba-related injuries. Half of the 14 injured sought care from medical providers for their injuries. Of the 21 injuries, the most frequently injured sites were knees (42%), ankles (14%), and shoulders (14%). Participants with Zumba-related injuries did not differ significantly in age, months of Zumba, or hours/class compared to those who did not experience injuries. However, participants who reported injuries took significantly more classes/week (3.8 versus 2.7 classes, P = .006) than non-injured participants. In logistic regression, taking more classes/week remained significantly associated with injuries (odds ratio 3.6 [95% confidence interval 1.5 - 8.9, P = .006]) after controlling for age, gender, months of Zumba, and hours/class. Given Zumba's health benefits, our finding that 1 in 4 Zumba participants have experienced injuries indicates the need to improve Zumba routines, instructor training, and health provider counseling to reduce injury risk.
尊巴是一项广受欢迎的、受拉丁风格启发的舞蹈健身项目，在150个国家拥有约1400万参与者。然而，关于参与者受伤率或受伤类型的公开数据很少。我们对夏威夷5个尊巴课程中的49名成年人（参与率100%）进行了便利抽样调查。参与者描述了之前任何与尊巴相关的损伤情况。我们使用t检验和逻辑回归来确定参与者的人口统计学特征或尊巴课程强度是否与损伤有关。参与者大多为女性（82%），平均年龄43.9岁（范围19至69岁），平均每周上3节课程（每节1 - 2小时），平均时长为11个月。14名参与者（29%）报告了21起之前与尊巴相关的损伤。这14名受伤者中有一半因伤寻求医疗服务提供者的治疗。在这21起损伤中，最常受伤的部位是膝盖（42%）、脚踝（14%）和肩膀（14%）。与未受伤的参与者相比，有尊巴相关损伤的参与者在年龄、参与尊巴的月数或每节课时长方面没有显著差异。然而，报告受伤的参与者每周上课节数（3.8节对2.7节，P = 0.006）明显多于未受伤的参与者。在逻辑回归中，在控制了年龄、性别、参与尊巴的月数和每节课时长后，每周上课节数较多仍与损伤显著相关（优势比3.6 [95%置信区间1.5 - 8.9，P = 0.006]）。鉴于尊巴对健康有益，我们发现四分之一的尊巴参与者曾受过伤，这表明需要改进尊巴课程编排、教练培训以及医疗服务提供者的咨询，以降低受伤风险。
