RESUMO
ABSTRACT Objective: To evaluate the prevalence and characteristics of musculoskeletal injuries associated with CrossFit® practitioners and the relationship of this prevalence among those who concomitantly perform resistance training (RT). Methods: Cross-sectional study in which adult participants of both sexes were included, who answered a mixed morbidity questionnaire adapted. The participants were allocated into groups according to whether or not they practiced another modality along with CrossFit®, with emphasis on RT. Analytical and descriptive statistics procedures were used, with a statistical significance level of 5% (p<0.05). Results: A total of 179 participants were included in the study. Prevalences of musculoskeletal injuries were observed in the overall study sample of 32.4% and in those who perform CrossFit® with RT of 30.8%. The injury prevalence ratio for this group was 0.95, with lower injury prevalence for the upper limbs (p=0.03) and lower limbs (p=0.02). It is worth noting that 96% of the CrossFit® and RT practitioners did strength training focused only on the upper and/or lower limb musculatures, without specific training for the anatomical segment of the Core (lumbar and pelvis). Conclusion: RT associated with CrossFit® and covering all anatomical segments, can be considered a protective factor for the occurrence of musculoskeletal injuries in CrossFit®. Level of Evidence IV; Case Series.
RESUMEN Objetivo: Evaluar la prevalencia y las características de las lesiones musculoesqueléticas asociadas a los practicantes de CrossFit® y la relación entre esta prevalencia y los que realizan simultáneamente entrenamiento de resistencia (ER). Métodos: Se trató de un estudio transversal en el que participaron adultos de ambos sexos que respondieron a un cuestionario adaptado de morbilidad mixta. Los participantes se dividieron en grupos según practicaran o no otro deporte junto con CrossFit®, en particular entrenamiento de resistencia. Se utilizaron procedimientos estadísticos analíticos y descriptivos, con un nivel de significación estadística del 5% (p<0,05). Resultados: Se incluyó en el estudio a un total de 179 participantes. Hubo una prevalencia de lesiones musculoesqueléticas en la muestra global del estudio del 32,4% y en los que practicaban CrossFit® con ER del 30,8%.El ratio de prevalencia de lesiones para este grupo fue de 0,95, con una menor prevalencia de lesiones en las extremidades superiores (p=0,03) y en las extremidades inferiores (p=0,02).Cabe destacar que el 96% de los practicantes de CrossFit® y ER realizaban entrenamientos de fuerza centrados únicamente en la musculatura de los miembros superiores y/o inferiores, sin realizar entrenamientos específicos para el segmento anatómico del Core (regiones lumbar y pélvica). Conclusión: El ER asociado al CrossFit® y que cubre todos los segmentos anatómicos puede ser considerado un factor protector contra la ocurrencia de lesiones músculo-esqueléticas en CrossFit®. Nivel de Evidencia IV; Serie de Casos.
RESUMO Objetivo: Avaliar a prevalência e as características das lesões musculoesqueléticas associadas aos praticantes de CrossFit® e a relação dessa prevalência entre aqueles que realizam de forma concomitante o treinamento resistido (TR). Métodos: Estudo transversal, no qual foram incluídos participantes adultos de ambos os sexos, que responderam a um questionário misto de morbidade adaptado. Os participantes foram divididos em grupos de acordo com a prática ou não de outra modalidade juntamente ao CrossFit®, com destaque para o TR. Foram utilizados procedimentos de estatísticas analítica e descritiva, com um nível de significância estatística de 5% (p<0,05). Resultados: Foram incluídos no estudo 179 participantes. Observaram-se prevalências de lesões musculoesqueléticas na amostra geral do estudo de 32,4% e naqueles que realizam o CrossFit® com TR de 30,8%. A razão de prevalência de lesões para esse grupo foi de 0,95, com menor prevalência de lesões para os membros superiores (p=0,03) e inferiores (p=0,02). Vale a pena destacar que 96% dos praticantes de CrossFit® e TR realizaram treinamentos de força com foco apenas nas musculaturas dos membros superiores e/ou inferiores, sem realização de treinamento específico para o segmento anatômico do Core (regiões lombar e pelve). Conclusão: O TR associado ao CrossFit® e com abrangência a todos os segmentos anatômicos pode ser considerado um fator de proteção para a ocorrência de lesões musculoesquelética no CrossFit®. Nível de Evidência IV; Série de Casos.
RESUMO
PURPOSE: To evaluate the prevalence and characteristics of orthopedic injuries associated with the technical-tactical profiles of Brazilian Jiu-Jitsu (BJJ) fighters, according to the fighters' graduation level (beginner and advanced). PATIENTS AND METHODS: Cross-sectional study, which included the participation of amateur and professional BJJ athletes, aged between 18 and 60 years and practitioners of the sport for at least six months. All answered a mixed self-reported morbidity questionnaire. Participants were divided into four groups, according to the technical-tactical profile in the fight (keeper and passer) and the fighter's graduation level (beginner and advanced), and also into four subgroups, divided by joining the groups in pairs above. Descriptive and analytical statistical procedures were used, with a level of statistical significance set at 5% (p < 0.05). RESULTS: A total of 198 participants were included in the study. There was a higher prevalence of musculoskeletal injuries in advanced fighters (p<0.001), with no significant difference between the profiles of guard and passer fighters. Sprains were the most common type of injury in all studied groups and subgroups. The anatomical segments knee and shoulder, respectively, were the most affected in all groups, and both segments showed significant associations of the athletes in the advanced and guard groups. CONCLUSION: The study showed important data for creation of specifics injury prevention protocols, through the higher prevalence of injuries in athletes of the advanced profile and in the segments of the knee and shoulder, with emphasis on the guard fighters.
