Abstract
ABSTRACT:Objective:To correlate CrossFit-related injuries with previous sedentary lifestyle, and to investigate other factors potentially associated with higher rates of injury among practitioners.Methods: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.Results: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).Conclusion: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.
Highlights
CrossFit is a strengthening and conditioning program based on high intensity functional movement created by Glassman in 2000.(1) Increasing popularity of this fitness program worldwide has sparkled the interest of physically active adults.[2]. The huge growth in (the number of CrossFit practitioners raised concerns about potential practice-related injuries.[3,4]
Spinal and knee injuries has been reported.[5,6,7] no evidence that CrossFit is associated with a higher incidence of injuries relative to other sports has been given so far and the rate of CrossFit-related injuries (0.74 to 3.3 per 1,000 hours of training) is similar to sports such as weightlifting, gymnastics and tennis.[5,8,9] Risk factors for higher incidence of CrossFit-related injuries are athletic skills, hours of training, participation in competitions and trainer supervision.[5,6,7]
To correlate CrossFit-related injuries with previous sedentary lifestyle, and to investigate other factors potentially associated with higher rates of injury among practitioners
Summary
To correlate CrossFit-related injuries with previous sedentary lifestyle, and to investigate other factors potentially associated with higher rates of injury among practitioners. Methods: 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. Conclusion: The incidence of CrossFit-related injuries did not differ significantly between previously sedentary and physically active participants. Objetivo: Correlacionar as lesões durante a prática do CrossFit com sedentarismo prévio e pesquisar outros fatores possivelmente relacionados ao aumento da taxa de lesão entre os praticantes. 35,5% declararam história de alguma lesão relacionada ao CrossFit. Os locais mais frequentes foram ombro e cotovelo (60,5%), coluna lombar (30,3%), e punho e mão (16,3%). Descritores: Crossfit; Ferimentos e lesões; Atletas; Comportamento sedentário; Exercício físico einstein (São Paulo). 2021;19:1-5
