BackgroundBrazilian jiu-jitsu is characterized by musculoskeletal disorders and high occurrence of sports injuries. The present study was aimed to analyze some internal factors, as well as to describe occurrence and characteristics of retrospective musculoskeletal injuries in different age groups of Brazilian jiu-jitsu practitioners.MethodsOne hundred ninety-three Brazilian jiu-jitsu practitioners, which were divided into three age groups: Adolescent, Adult, and Master. Besides anthropometric characterization, standard clinical tests were conducted to analyze the global and segmental joint flexibility, lumbar spine range of motion, and handgrip strength. Sports injury occurrence and total physical activity were obtained from an adapted morbidity survey and International Physical Activity Questionnaire - Short Form (IPAQ-SF), respectively.ResultsA total of 247 cases of retrospective injuries was registered (1.27 injury/ participant). Occurrence of rectus femoral muscle retraction in the right leg was increased within Master. Adult and Master have exhibited higher occurrence of sports injuries than Adolescent group (p < 0.05). Joint injuries were the most common sports-related injuries by all Brazilian jiu-jitsu practitioners. While female gender and exposure time constituted the most predictive variables for sports injury occurrence in Adolescent, graduation level was more associated with sports injuries occurrence in Adult.ConclusionsJoint injuries derived from combat demands were the main sports injury in all age categories of Brazilian jiu-jitsu. Master subjects presented a higher occurrence of clinical changes and retrospective musculoskeletal injuries in relation to other age groups. Female gender and exposure time constituted the main predictive factors in adolescent subjects, while graduation category was more directly associated with retrospective injury onset in the Adult group.
Introduction: In soccer, the players’ positions have been associated with specific functional overload, which may cause sports injuries. Objective: To investigate the occurrence and characterize sport injuries according to soccer player position. Methods: 232 male soccer players (129 professionals and 103 amateurs) from different sport teams in Mato Grosso do Sul, Brazil, were distributed in groups according to their soccer player position. Besides anthropometric characteristics, sports injuries were registered by using a referred morbidity survey. The occurrence of injuries was analyzed by means of the Goodman Test. Logistic regression models were used to investigate the relationship between different risk factors and the occurrence/-recurrence of sports injuries. Results: Forwards showed higher occurrence rates of sport injuries than other soccer position groups. Joint injuries in lower limbs constituted the most frequent registered cases. Muscle injuries in the back region were the most registered sports injuries among midfielders, while muscle damages in lower limbs were the primary injuries registered for other line positions. In the etiologic context, contact was the main cause of sports injuries in all groups. Most athletes (195) reported recurrence of sports injuries. Conclusion: The occurrence of sports injuries was higher among forwards. Traumatic joint and muscle injuries were the most prevalent registers in all line positions.
RESUMO A prática de judô integra situações variadas de contato físico e exigências específicas, tornando-o uma modalidade competitiva e com alto índice de lesões musculoesqueléticas (LME). Este estudo transversal teve por objetivo descrever a epidemiologia de LME e analisar a relação entre diferentes características e a ocorrência de lesão em judocas. A casuística integrou 111 participantes de ambos os sexos. Para tomar informações sobre lesões, utilizou-se um inquérito de morbidade referida. Para análise estatística, foi empregado o teste de Goodman de proporções multinomiais. A relação entre fatores associados com LME foi avaliada por meio de regressão logística. Foram relatados 135 LME, com prevalência de 65% (72 esportistas), totalizando 1,22 LME/atleta. A maioria dos relatos foi constituída por lesões articulares decorrentes de traumas (n=50 casos, 37%), sendo que entorse de tornozelo (25,2%) e luxação de ombro (17,8%) foram os casos com maior frequência. Entre as lesões ósseas, verificou-se maior proporção de casos graves (25 casos; 18,5%). Sexo e carga horária semanal constituíram-se como as principais características preditivas para ocorrência de LME no judô (p<0,001). Conclui-se que as lesões articulares traumáticas em tornozelo e ombro foram as principais LME no judô. Sexo masculino e maior carga horária semanal constituíram-se como as principais características preditivas de lesão entre judocas.
<p>Este estudo teve por objetivo analisar a epidemiologia de lesões musculoesqueléticas (LME) no futebol, relacionando-as com frequência de prática e nível de atividade física. A casuística integrou 126 participantes homens, praticantes regulares de futebol amador em diferentes centros poliesportivos de Campo Grande/MS. Os participantes foram distribuídos em quatro grupos, de acordo com a frequência semanal de prática de futebol: G1, um dia, G2, dois dias, G3, três dias, e G4, quatro ou mais dias de atividade, com duração de 10 a 60 minutos. Para a tomada de informações sobre o nível de atividade física e LME, foram utilizados, respectivamente, o questionário internacional de atividade física (IPAQ) e um inquérito de morbidade referida. Não se constatou uma associação entre prática de futebol e nível de atividade física; o G4 mostrou maiores valores de gasto metabólico. Foram registrados 96 LME, envolvendo 87 participantes (69%), totalizando 1,52 LME/ praticante. Constatou-se um predomínio de lesões musculares (36%) e articulares (34%) em membros inferiores. O trauma constituiu o principal mecanismo de lesão (28%), destacando-se como a maior causa no G3. Foi possível constatar que a frequência de prática de futebol não se associa diretamente com a ocorrência de LME entre jogadores amadores de futebol.</p>
