Prevalência e características das lesões musculoesqueléticas em praticantes de Crossfit

Abstract

Introduction: CrossFit promotes improvement of overall physical capacity, positively influencing the criteria that define physical fitness. Because it is a high-intensity modality, when practiced incorrectly and excessively, it can precipitate musculoskeletal injuries. Objective: To identify the prevalence and describe the characteristics of musculoskeletal injuries in CrossFit practitioners. Methodology: Cross-sectional, descriptive and quantitative study, carried out with 300 CrossFit practitioners. Participants underwent the Referred Morbidity Survey (IMR) to identify and characterize injuries. The research was carried out in 9 boxes in the metropolitan region of Goiânia. Results: Among the participants, 121 had injuries (40,4%) and 179 did not (59,7%). The most prevalent injuries were muscle strains (18,5%, n=28), tendinopathies (15,2%, n=23), nonspecific acute pain (10%, n=15) and dislocations (9,3%, n=14). Regarding the anatomical location of the injuries, the most common were the shoulder (24,5%, n=37), lower back (16,6%, n=25) and thigh (9,9%, n=15). The main injury mechanisms were overuse (45,1%, n=68), jerk (13,9%, n=21) and rotation (10,6%, n=16). The exercises most associated with injuries were the Dead lift (15,9%, n=24), Snatch (13,9%, n=21) and Pull up (13,2%, n=20). Most injuries occurred during training (90,7%, n=137). Conclusion: We found a moderate prevalence of musculoskeletal injuries in CrossFit practitioners, the main ones being muscle strain, tendinopathy, nonspecific acute pain and dislocations, especially affecting the shoulder, lower back, thigh and knee.
