- Abstract
Background: CrossFit® is a popular high-intensity, functional strength sport. Reviews of CrossFit® epidemiology lack a clear definition of 'injury'. Objectives: Based on a three-step definition of 'injury' with time-loss and medical attention, the existing literature was to be reviewed to determine injury rates in CrossFit® and the most affected body regions. Methods: Following the PRISMA-statement, four literature databases were searched for studies related to epidemiology in CrossFit®. Studies found were reviewed for evidence and quality of reporting through the OCEBM Levels of Evidence and the STROBE statement. Results: Thirty-two studies were included in the qualitative review and fourteen studies were included in the meta-analysis. The included studies were of level 3 and 4 of evidence and reported 14-22 items of the STROBE-checklist. A prevalence of 30.3% (95% CI: 25.3-35.3%) and an incidence of 3.20/1,000 hours (95% CI: 2.06-4.34) were calculated for musculoskeletal injuries in CrossFit®. Spine (26.8%, 95% CI: 20.6-33.0%), shoulder (25.9%, 95% CI: 20.1-31.6%), and knee (15.8%, 95% CI: 11.8-19.7%) were most affected. Conclusion: Musculoskeletal injury rates and affected body regions in CrossFit® are comparable to weightlifting and powerlifting. These findings suggest that recommendations for injury prevention in CrossFit® might not differ from generalized recommendations in strength sports. Studies of higher quality are needed to improve epidemiology data.
