          Abstract

          RESUMO Este estudo teve como objetivo investigar a prevalência de lesões durante um ano em praticantes de CrossFit® e a influência das características da prática esportiva e demográficas nessas lesões. Foi realizado estudo de coorte retrospectivo com 180 praticantes de CrossFit®, que responderam a um questionário sobre: características demográficas (idade, massa corporal, altura e sexo), características da prática esportiva (tempo de prática esportiva, frequência e duração de treino, formação de carga e prática de outro esporte) e ocorrência e características da lesão (quantidade, região lesionada e estrutura acometida). Por meio do teste de Mann-Whitney U, investigou-se a diferença nas variáveis contínuas entre aqueles com e sem histórico de lesão. Utilizando o teste de qui-quadrado e o teste exato de Fisher, avaliou-se a associação entre variáveis categóricas e a presença ou não de lesão. O teste de qui-quadrado goodness-of-fit foi aplicado para investigar se a frequência observada de lesões por região do corpo e por tipo era diferente da esperada. A prevalência de lesão foi de 63%, e aqueles com histórico de lesão tinham menor tempo de prática esportiva. A presença de histórico de lesão foi associada a menor frequência semanal e diária e menor duração de treinos, assim como à formação de carga Scale. A frequência de lesão em perna, joelho, coluna lombar, ombro e punho, assim como do tipo músculo e tendão foi acima da esperada. As demais variáveis não apresentaram diferença entre grupos ou não foram associadas à presença de lesão. Logo, a maioria dos investigados relatou lesão que foi influenciada pelas características da prática esportiva, e não pelas demográficas.

          ABSTRACT This study aimed to investigate the prevalence of injuries in CrossFit® practitioners and the influence of sports practice and demographic characteristics on these injuries. A retrospective cohort study was carried out with 180 CrossFit® practitioners who answered a questionnaire with demographic characteristics (age, body mass, height, and sex), sports characteristics (number of years practicing CrossFit®; training frequency, duration, and training program; and practice of other sports), and presence of any injury suffered and its characteristics (number of injuries, region, and type of injury). The Mann-Whitney U test investigated the difference in continuous variables between those with and without injury history. The chi-square test and Fisher’s exact test investigated the association between categorical variables and the presence or not of injury over the last year. The chi-square goodness-of-fit test investigated if the frequency of injuries per body location and type differed from the expected one. Injury prevalence was 63%. Participants with a history of injury showed a shorter time of CrossFit® practice. The presence of injury history was associated with lesser weekly and daily training frequency, shorter training duration, and Scale training program. The frequency of injuries on leg, knee, lumbar spine, shoulder, and wrist, and the muscle and tendon was greater than expected. The other variables were neither different between groups nor associated with injury presence. Thus, most participants presented injury over the last year, influenced by the sports characteristics but not by demographic characteristics.

          RESUMEN Este estudio tuvo como objetivo investigar la prevalencia de lesiones en practicantes de CrossFit® durante un año y la influencia de las características deportivas y demográficas en estas lesiones. Se trata de estudio de cohorte retrospectivo, realizado con 180 practicantes de CrossFit®, quienes respondieron a un cuestionario que contenía: características demográficas (edad, masa corporal, altura y sexo), características de la práctica deportiva (tiempo de práctica deportiva, frecuencia y duración del entrenamiento, carga de entrenamiento y práctica de otro deporte) y ocurrencia y características de la lesión (cantidad, región lesionada y estructura afectada). Para el análisis de la diferencia en las variables continuas entre los practicantes con y sin antecedentes de lesiones, se utilizó la prueba U de Mann-Whitney. Se evaluó la asociación entre las variables categóricas y la presencia o ausencia de lesión mediante la prueba de chi-cuadrado y la prueba exacta de Fisher. La prueba de chi-cuadrado goodness-of-fit se aplicó para investigar si la frecuencia de lesiones por parte del cuerpo y por tipo era distinta de lo esperado. La prevalencia de lesión fue del 63%, y los practicantes con antecedente de lesión tenían menor tiempo de práctica deportiva. La presencia de antecedentes de lesión se asoció con una menor frecuencia semanal/diaria y una menor duración del entrenamiento, así como con la formación de la carga de Scale. La frecuencia de lesiones en la pierna, la rodilla, la columna lumbar, el hombro y la muñeca, así como de tipo muscular y tendinoso fue mayor a la esperada. Las demás variables no mostraron diferencia entre grupos o no se asociaron con la presencia de lesión. Por lo tanto, la mayoría de los participantes reportaron presentar una lesión que estuvo influenciada por las características de la práctica deportiva, y no por la demografía.

          Incidence, severity, aetiology and prevention of sports injuries. A review of concepts.

          Notwithstanding the healthy influence of sporting activities on risk factors, in particular those of cardiovascular disease, it is becoming increasingly apparent that sports can present a danger to health in the form of sports injuries. The extent of the sports injury problem calls for preventative action based on the results of epidemiological research. For the interpretation of these facts uniform definitions are needed and limitations of research designs should be known. Measures to prevent sports injuries form part of what is called the 'sequence of prevention'. Firstly the extent of the sports injury problem must be identified and described. Secondly the factors and mechanisms which play a part in the occurrence of sports injuries have to be identified. The third step is to introduce measures that are likely to reduce the future risk and/or severity of sports injuries. This measure should be based on the aetiological factors and the mechanism as identified in the second step. Finally the effect of the measures must be evaluated by repeating the first step. In this review some aspects of the first and second step of the sequence of prevention are discussed. The extent of the sports injury problem is often described by injury incidence and by indicators of the severity of sports injuries. Sports injury incidence should preferably be expressed as the number of sports injuries per exposure time (e.g. per 1000 hours of sports participation) in order to facilitate the comparability of research results. However, one should realise that the outcome of research applying this definition of sports injury incidence is highly dependent on the definitions of 'sports injury' and 'sports participation'. The outcome of such research also depends on the applied research design and research methodology. The incidence of sports injuries depends on: the method used to count injuries (e.g. prospective vs retrospective); the method used to establish the population at risk; and on the representativeness of the sample. Severity of sports injuries can be described on the basis of 6 criteria: the nature of the sports injury; the duration and nature of treatment; sporting time lost; working time lost; permanent damage; and cost. Here also uniform definitions are important and necessary in order to enhance the comparability of research data. In the second step of the 'sequence of prevention' the aetiological factors that play a role in the occurrence of a sports injury have to be identified by epidemiological studies. Epidemiological research on the aetiology of sports injuries requires a conceptual model.(ABSTRACT TRUNCATED AT 400 WORDS)

            Sports injuries and illnesses during the London Summer Olympic Games 2012.

            The Olympic Movement Medical Code encourages all stakeholders to ensure that sport is practised without danger to the health of the athletes. Systematic surveillance of injuries and illnesses is the foundation for developing preventive measures in sport. To analyse the injuries and illnesses that occurred during the Games of the XXX Olympiad, held in London in 2012. We recorded the daily occurrence (or non-occurrence) of injuries and illnesses (1) through the reporting of all National Olympic Committee (NOC) medical teams and (2) in the polyclinic and medical venues by the London Organising Committee of the Olympic and Paralympic Games' (LOCOG) medical staff. In total, 10 568 athletes (4676 women and 5892 men) from 204 NOCs participated in the study. NOC and LOCOG medical staff reported 1361 injuries and 758 illnesses, equalling incidences of 128.8 injuries and 71.7 illnesses per 1000 athletes. Altogether, 11% and 7% of the athletes incurred at least one injury or illness, respectively. The risk of an athlete being injured was the highest in taekwondo, football, BMX, handball, mountain bike, athletics, weightlifting, hockey and badminton, and the lowest in archery, canoe slalom and sprint, track cycling, rowing, shooting and equestrian. 35% of the injuries were expected to prevent the athlete from participating during competition or training. Women suffered 60% more illnesses than men (86.0 vs 53.3 illnesses per 1000 athletes). The rate of illness was the highest in athletics, beach volleyball, football, sailing, synchronised swimming and taekwondo. A total of 310 illnesses (41%) affected the respiratory system and the most common cause of illness was infection (n=347, 46%). At least 11% of the athletes incurred an injury during the games and 7% of the athletes' an illness. The incidence of injuries and illnesses varied substantially among sports. Future initiatives should include the development of preventive measures tailored for each specific sport and the continued focus among sport bodies to institute and further develop scientific injury and illness surveillance systems.

              CrossFit Overview: Systematic Review and Meta-analysis

              Background CrossFit is recognized as one of the fastest growing high-intensity functional training modes in the world. However, scientific data regarding the practice of CrossFit is sparse. Therefore, the objective of this study is to analyze the findings of scientific literature related to CrossFit via systematic review and meta-analysis. Methods Systematic searches of the PubMed, Web of Science, Scopus, Bireme/MedLine, and SciELO online databases were conducted for articles reporting the effects of CrossFit training. The systematic review followed the PRISMA guidelines. The Oxford Levels of Evidence was used for all included articles, and only studies that investigated the effects of CrossFit as a training program were included in the meta-analysis. For the meta-analysis, effect sizes (ESs) with 95% confidence interval (CI) were calculated and heterogeneity was assessed using a random-effects model. Results Thirty-one articles were included in the systematic review and four were included in the meta-analysis. However, only two studies had a high level of evidence at low risk of bias. Scientific literature related to CrossFit has reported on body composition, psycho-physiological parameters, musculoskeletal injury risk, life and health aspects, and psycho-social behavior. In the meta-analysis, significant results were not found for any variables. Conclusions The current scientific literature related to CrossFit has few studies with high level of evidence at low risk of bias. However, preliminary data has suggested that CrossFit practice is associated with higher levels of sense of community, satisfaction, and motivation.
