RESUMO

Objective To investigate the epidemiology of injury types among jiu-jitsu practitioners, as well as the incidence regarding different skill and experience levels, through the question: "What are the characteristics and prevalence of musculoskeletal injuries in Jiu-Jitsu practitioners?". Methods Since the beginning of the study, in August 2020, we conducted a search on the MEDLINE, LILACS, and SciELO electronic databases. We included cross-sectional studies published between 2018 and 2023 on the epidemiology of the types of injuries among jiu-jitsu practitioners that compared their incidence regarding different levels of ability and experience. Two independent researchers performed the data extraction and assessed the risk of bias. Results Seven studies were included. The common outcomes involved 2,847 jiu-jitsu practitioners. A high prevalence in the knee joint and chest and rib areas was reported. Considering the difference in experience level among the practitioners, we could observe that most of the individuals included were beginners. Among the age groups observed, male practitioners older than 30 years of age were the ones who presented the highest rate of musculoskeletal injury, especially during training sessions. Conclusion There is a high prevalence of musculoskeletal injuries among jiu-jitsu practitioners. The most affected anatomical segments are the knee joint, the chest, and the rib region, followed by the shoulder joint. The related factors change according to certain variables, being more common during training in male individuals over 30 years of age and beginners in the sport.

Resumo Objetivo Investigar a epidemiologia dos tipos de lesões entre praticantes de jiu-jitsu e sua incidência em diferentes níveis de habilidade e experiência por meio da questão: "Quais as características e a prevalência das lesões musculoesqueléticas em praticantes de jiu-jitsu?" Métodos Desde o início do estudo, em agosto de 2020, foram pesquisados os bancos de dados MEDLINE, LILACS e SciELO. Foram incluídos estudos transversais, publicados entre 2018 e 2023, que investigaram a epidemiologia dos tipos de lesões ocorridas entre praticantes de jiu-jitsu e compararam sua incidência em diferentes níveis de habilidade e experiência. Para tanto, dois pesquisadores independentes realizaram a extração dos dados e avaliaram o risco de viés. Resultados Sete estudos foram incluídos. Os resultados comuns envolveram 2.847 praticantes de jiu-jitsu. Houve uma alta prevalência de lesão na articulação do joelho e nas áreas do tórax e das costelas. Considerando a diferença de nível de experiência entre os praticantes, pôde-se observar que a maioria dos indivíduos incluídos eram iniciantes. Entre as faixas etárias observadas, homens acima de 30 anos de idade foram os que mais apresentaram lesões musculoesqueléticas, principalmente durante os treinos. Conclusão Houve uma alta prevalência de lesões musculoesqueléticas entre os praticantes de jiu-jitsu. Os segmentos anatômicos mais acometidos foram a articulação do joelho, o tórax e a região das costelas, seguidos da articulação do ombro. Os fatores relacionados mudaram de acordo com algumas variáveis, sendo mais comuns durante o treinamento em indivíduos do sexo masculino com mais de 30 anos e iniciantes na modalidade.

RESUMO

O objetivo do estudo foi analisar a percepção dos alunos do Ensino Médio em relação às lutas enquanto unidade temática nas aulas de Educação Física. Para tanto, a pesquisa se caracterizou como de natureza aplicada, do tipo descritiva, com a participação de 17 alunos do Ensino Médio. A pesquisa foi realizada em dois momentos, sendo o primeiro referente ao desenvolvimento de uma intervenção pedagógica do conteúdo de lutas, e o segundo a partir da aplicação de um questionário. Os resultados apontaram que 82% dos participantes usufruíram de uma prática positiva e prazerosa e 94% dos participantes afirmaram ausência de violência. Assim, compreende-se que as lutas na escola se configuram como um mediador na transformação das apreciações de concepções pelos participantes (AU).

RESUMO

El Tang Soo Do es un arte marcial versátil que destaca por el uso de la cadera para sus gestos técnicos. El karate es una de las artes marciales más atractivas alrededor del mundo. Tanto karate como Tang Soo Do comparten un estilo firme en sus técnicas y combate. Sin embargo, algunas de las formas en Tang Soo Do poseen un estilo suave similar al kung fu y al tai chi. Por ello, es interesante describir y comparar las capacidades físicas y la composición corporal de los practicantes de Tang Soo Do y karate a nivel recreativo. Para ello, se realizó una búsqueda en Medline® y Web of Science® durante enero de 2021. Se escogieron 10 estudios, organizando sus datos según composición corporal, fuerza muscular, resistencia muscular, flexibilidad y VO2max. Se encontraron 2 estudios en practicantes recreativos de Tang Soo Do y 8 en karate a nivel mundial, por lo que no existen suficientes estudios que permitan describir y comparar adecuadamente las capacidades físicas y la composición corporal entre sus practicantes a nivel recreativo; sin embargo, los resultados encontrados indican que es importante realizar más investigaciones que midan estas variables, con la finalidad de considerar en base a la evidencia alTang Soo Do como una importante opción para el bienestar físico y mental de sus practicantes. Las investigaciones futuras pueden evaluar estos datos en distintos grupos etarios, localización, tiempo de entrenamiento o tipos de competiciones según formas, combate o mixto. Además, se pueden realizar estudios comparativos en los practicantes de Tang Soo Do que permita a este arte marcial ser desde la evidencia una importante opción de práctica en colegios y universidades, así como un estilo de vida para sus practicantes.

SUMMARY: Tang Soo Do is a versatile martial art that stands out for the use of the hip for its technical gestures. Karate is one of the most attractive martial arts around the world. Both karate and Tang Soo Do share a firm style in their techniques and combat. However, some of the forms in Tang Soo Do possess a gentle style similar to Kung Fu and Tai Chi. Therefore, it is interesting to describe and compare the physical abilities and body composition of recreational Tang Soo Do and karate practitioners. A search was carried out in Medline® and Web of Science® during January 2021. Following the search 10 studies were chosen, organizing their data according to body composition, muscular strength, muscular resistance, flexibility and VO2max. Two studies were found on recreational Tang Soo Do practitioners and eight on karate worldwide, hence, there are not enough studies to adequately describe and compare physical abilities and body composition among recreational practitioners; However, the results found, indicate that it is important to conduct further research to measures these variables, in order to consider Tang Soo Do as an important option for the physical and mental well-being of its practitioners. Future research can evaluate these data can be evaluated in different age groups, location, training time or types of competitions according to forms, combat or mixed. In addition, comparative studies can be carried out on Tang Soo Do practitioners that allow this martial art to become an important option for practice in schools and universities, as well as a lifestyle for its practitioners.

RESUMO

The distal rupture of the biceps brachii muscle tendon (DBT) accounts for 3% of biceps ruptures. Diagnosis typically relies on high clinical suspicion and complementary imaging studies, with >90% of cases documented in males between the fourth and sixth decades of life. Reports of DBT ruptures in females are scarce, mostly involving partial and degenerative injuries. Here, we present an unprecedented case of a 28-year-old female professional mixed martial arts athlete with a total traumatic DBT rupture. The athlete underwent surgical repair using anchor reattachment technique. No complications were observed, and the athlete showed satisfactory outcomes, being cleared for physiotherapy after 2 weeks and returning to sports after a 3-month postoperative period.

RESUMO

OBJECTIVE: Evaluate injury trends in Brazilian Jiu Jitsu (BJJ) participation by presenting to U.S. emergency departments over a 10-year period and formulate an injury profile. METHODS: The U.S. Consumer Product Safety Commission's (CPSC) National Electronic Injury Surveillance System (NEISS) database was queried for martial arts related injuries from 1 January 2012 to 31 December 2021. Codes and narratives were examined to compile data for patients sustaining BJJ-related injuries. RESULTS: From 1 January 2012 to 31 December 2021 there were 7,722 (NE = 282,315) ED-diagnosed martial arts related injuries with 911 (NE = 36,023) BJJ-related injuries identified. Regression analysis demonstrated an increasing trend in the annual incidence of Brazilian Jiu Jitsu injuries presenting to the ED (R2 = 0.934; SE = 2.069: p < .0001). Average age was 25.68 years of age (range 4-83). The most common injury diagnoses were sprains/strains and other/not listed at 27.68% and 26.39%. The most commonly injured body parts were the upper trunk, and the shoulder comprising 13.66% and 12.14% of injured body parts, respectively. The most commonly fractured region was toes, at 14.15% of all fractures. The most common dislocations occurred at the shoulder and knee, at 32.49% and 28.45% of dislocations, respectively. The most common mechanisms of injury specifically identified were indeterminate contact between players, fall onto ground, or fall onto another player comprising 18.62% and 17.17%, of injuries, respectively. CONCLUSION: There was an increasing trend of BJJ-related injuries presenting to U.S. Emergency Departments. The most common diagnoses and body parts injured were sprains/strains and upper trunk and shoulder, respectively. The most commonly fractured and dislocated regions were toes and shoulder, respectively. The most common mechanisms of injury were indeterminate contact or falling. This study provides novel information concerning trends in injury and injury profiles for Brazilian Jiu Jitsu related injuries.

RESUMO

Resumen Se plantearon dos objetivos: (O1) analizar los efectos de una intervención de artes marciales sobre las actitudes hacia la violencia; (O2) Señalar estrategias pedagógicas útiles para este tipo de programas. Se diseñó un estudio de caso dentro de un proceso de investigación-acción participativa. Participaron siete estudiantes de educación primaria (6-11 años) usuarios de un centro de día. Se implementó una intervención de ocho semanas (15 sesiones) basada en el Brazilian Jiu-Jitsu (BJJ). Se recogió información a través de grupos de discusión, entrevistas individuales y diario del profesor. El análisis produjo tres categorías/temas (nueve subcategorías): cambios (actitudes hacia la violencia, comportamiento, relaciones sociales), sensaciones (positivas, negativas) y estrategias pedagógicas (contacto físico, etiqueta, encargado, juegos con momentos de calma). Los objetivos planteados fueron ampliamente conseguidos, disminuyendo las actitudes hacia la violencia de los participantes (O1) y señalando estrategias pedagógicas para poder replicar la intervención en diferentes contextos (O2). Por lo tanto, el programa puede considerarse un éxito para la mejora de las actitudes hacia violencia de jóvenes en riesgo de exclusión que acudan a un centro de día.

Resumo Foram definidos dois objetivos: (O1) analisar os efeitos de uma intervenção de artes marciais nas atitudes face à violência; (O2) Apontar estratégias pedagógicas para esse tipo de programa. Um estudo de caso foi desenhado dentro de um processo de pesquisa-ação participativa. Participaram sete alunos do ensino básico (6-11 anos), utentes de um centro de dia. Foi implementada uma intervenção de oito semanas (15 sessões) baseada no Brazilian Jiu-Jitsu. As informações foram coletadas por meio de grupos focais, entrevistas individuais e diário do professor. A análise produziu três categorias/temas (nove subcategorias): mudanças (atitudes perante à violência, comportamento, relações sociais), sensações (positivas, negativas) e estratégias pedagógicas (contato físico, etiqueta, gerente, jogos com momentos de calma). Os objetivos declarados foram em grande parte alcançados através da redução das atitudes dos participantes face à violência (O1) e da indicação de estratégias pedagógicas para poder replicar a intervenção em diferentes contextos (O2). Portanto, o programa pode ser considerado um sucesso por melhorar as atitudes face à violência entre os jovens em risco de exclusão que frequentam um centro de dia.

Abstract Two objectives were set: (O1) to analyze the effects of a martial arts intervention on attitudes towards violence; (O2) Point out pedagogical strategies for this type of program. A case study was designed within a participatory-action-research process. Seven primary school students (6-11 years old), users of a day center, participated. An eight-week intervention (15 sessions) based on Brazilian Jiu-Jitsu was implemented. Information was collected through focus groups, individual interviews and the teacher's diary. The analysis produced three categories/themes (nine subcategories): changes (attitudes towards violence, behavior, social relationships), sensations (positive, negative) and pedagogical strategies (physical contact, etiquette, manager, games with moments of calm). The stated objectives were largely achieved by reducing participants' attitudes towards violence (O1) and indicating pedagogical strategies to be able to replicate the intervention in different contexts (O2). Therefore the program can be considered a success for improving attitudes towards violence among young people at risk of exclusion who attend a day center.

RESUMO

ABSTRACT BACKGROUND AND OBJECTIVES: A notable gap persists in understanding the prevalence of pain and musculoskeletal injuries in combat sports. This study offers a comprehensive exploration of the most affected anatomical regions. Such an investigation is pivotal for refining clinical strategies involving preventive measures and physiotherapeutic interventions. METHODS: This is a cross-sectional observational study. Individuals aged 18 years or over, combat sport modalities practitioners, of both genders, and capable of answering the questionnaire were included. Data were analyzed using descriptive statistics and the Chi-square test. RESULTS: The final sample consisted of 71 athletes. Female athletes practiced 12.65% Judo and 21.51% practiced Jiu-jitsu, while 26.58% of male athletes practiced Judo and 39.24% Jiu-jitsu. The mean age was 31.14±11.75 years, and body mass index of 27.69 kg/m2 (±5.31). The average time of practice was 8±10.59 years. The regions most affected by pain in the last 12 months were the lumbar spine (90%), knees (90%) and wrists/ hands (60%). Female Judo presented a significant index of pain in the last 12 months in the upper limbs, and the neck was the region identified as most responsible for limiting activities. In the last 7 days, the thoracic and lumbar spine regions were more significant. In female Jiu-jitsu, in the 12-month and 7-day analyses, the ankle/foot were the most affected regions when compared to the male gender, and the knees were identified as most responsible for limiting activities. CONCLUSION: A comprehensive description of the main regions affected by musculoskeletal disorders and pain is of fundamental importance for the development of prevention and physiotherapeutic treatment strategies.
