BACKGROUND/OBJECTIVES: CrossFit is one of the most popular yet controversial training regimens. Some groups extol the positive effects of its practice, while others argue that it is unsafe and that there is limited information. The aim of this study was to investigate, through a self-reported questionnaire, the epidemiology of Portuguese CrossFit training practitioners.
Statistical analyses, including Mann-Whitney U, chi-square, Spearman's rho correlations, and logistic regressions, were conducted.
A total of 288 practitioners completed the questionnaire, with 39.9% reporting injuries. These injuries occurred mainly during training, particularly when performing gymnastics exercises. Tendon (40.9%) and shoulder (46.1%) were the most common injuries. Key risk factors for injury included male gender (OR = 2.7), years of practice (4-6 years: OR = 7.22), heavier body weight (OR = 4.76), and higher weekly training volume (4-6 times per week).
Approximately 40% of CrossFit practitioners are expected to experience injuries, particularly in the shoulder and tendons. Injury risk is influenced by factors such as practice years, weekly training, sex, and body weight. These findings may help guide practitioners, coaches, and health professionals in better understanding the risk factors, mitigating injuries, and developing effective injury prevention strategies.
背景/目的：CrossFit是最受欢迎但也最具争议的训练方案之一。一些团体赞扬其训练的积极效果，而另一些人则认为它不安全且相关信息有限。本研究的目的是通过一份自我报告问卷，调查葡萄牙CrossFit训练从业者的流行病学情况。
进行了包括曼-惠特尼U检验、卡方检验、斯皮尔曼等级相关分析和逻辑回归分析在内的统计分析。
共有288名从业者完成了问卷，其中39.9%报告有受伤情况。这些损伤主要发生在训练期间，尤其是进行体操练习时。肌腱损伤（40.9%）和肩部损伤（46.1%）是最常见的损伤类型。受伤的关键风险因素包括男性（比值比=2.7）、训练年限（4 - 6年：比值比=7.22）、体重较重（比值比=4.76）以及每周训练量较大（每周4 - 6次）。
预计约40%的CrossFit从业者会受伤，尤其是肩部和肌腱部位。受伤风险受训练年限、每周训练量、性别和体重等因素影响。这些发现可能有助于指导从业者、教练和健康专业人员更好地理解风险因素、减轻损伤并制定有效的损伤预防策略。
