To correlate CrossFit-related injuries with previous sedentary lifestyle, and to investigate other factors potentially associated with higher rates of injury among practitioners.
A nationwide cross-sectional study involving CrossFit practitioners who received a digital questionnaire inquiring into CrossFit-related injuries, previous sedentary life, training intensity and experience, site of injury and general demographics.
This sample included 121 CrossFit practitioners, 34.7% of participants were sedentary prior to starting CrossFit practice, from these, 45.2% reported CrossFit-related injuries, compared to 30.4% from previously active practitioners (p=0.104). The shoulder/elbow (60.5%), lumbar spine (30.3%) and wrist/hand (16.3%) were the most common sites of injury among participants reporting CrossFit-related injuries (35.5%). Participants performing intense weight training were more prone to injuries than those practicing light or moderate weight training (p=0.043). On average, participants with a history of injury spent significantly more time training than those with no history of injury (68.4 and 61.7 minutes, respectively; p=0.044).
The incidence of CrossFit-related injuries did not differ significantly between previously sedentary and physically active participants. Intense weight training was associated with a higher incidence of injuries. The overall injury rate was 35.5%, similar to that found in previous studies, and the most common site of injury was shoulder/elbow.
探讨 CrossFit 相关损伤与既往久坐生活方式的相关性,并研究与从业人员较高损伤率相关的其他因素。
一项全国性横断面研究,涉及接受数字问卷调查的 CrossFit 从业人员,该问卷询问了与 CrossFit 相关的损伤、既往久坐生活、训练强度和经验、损伤部位以及一般人口统计学信息。
本样本包括 121 名 CrossFit 从业人员,34.7%的参与者在开始 CrossFit 训练前久坐,其中 45.2%报告了 CrossFit 相关损伤,而之前活跃的参与者中这一比例为 30.4%(p=0.104)。报告 CrossFit 相关损伤的参与者中,肩部/肘部(60.5%)、腰椎(30.3%)和腕/手(16.3%)是最常见的损伤部位(35.5%)。进行高强度举重训练的参与者比进行轻或中强度举重训练的参与者更容易受伤(p=0.043)。平均而言,有受伤史的参与者比没有受伤史的参与者训练时间明显更长(分别为 68.4 分钟和 61.7 分钟;p=0.044)。
既往久坐和活跃的参与者之间 CrossFit 相关损伤的发生率无显著差异。高强度举重训练与更高的损伤发生率相关。总体损伤率为 35.5%,与之前的研究相似,最常见的损伤部位是肩部/肘部。
