Objective: To determine the incidence and risk factors for injuries that occurred during the matches of the Brazilian Football Championship. Methods: A prospective study was carried out with the collection of data referring to injuries that occurred during the 2019 Brazilian Football Championship. The injuries were recorded by the responsible physician of each team, through an online injury mapping system. Results: Among the 645 athletes who were included in the study, 214 (33.2%) of the players had at least one injury during the tournament. In total, 257 injuries were recorded during the Brazilian Championship, with an average of 0.68 injuries per game. 59.1% of the injured athletes were over 26 years old. The most common type of injury was muscle strain (37.7%) and forwards were the most affected (33.6%). Conclusion: Muscle injuries were the most frequent in the tournament, with the thigh muscles being the most affected. Most of the affected players were over 26 years old, there were 20.5 injuries for every 1000 hours of play and the incidence of injuries was approximately 33%, with attackers being the most affected (33.6%). Level of Evidence III, Study of nonconsecutive patients; without consistently applied reference “gold” standard.

Resumo Objetivo Realizar uma avaliação prospectiva das lesões musculares ocorridas durante as partidas das séries A e B do Campeonato Brasileiro de Futebol Masculino dos anos de 2016 a 2018. Métodos Estudo de coorte prospectivo com coleta de dados referentes às lesões musculares ocorridas durante os jogos oficiais da primeira e segunda divisões do Campeonato Brasileiro de Futebol Masculino nas temporadas de 2016, 2017 e 2018. Resultados O número total de lesões musculares foi de 577 ao longo das 3 temporadas, havendo uma redução gradual e anual na incidência delas (219 lesões em 2016, 195 em 2017, e 163 em 2018), com diferença estatística significativa entre os anos de 2016 e 2018. As lesões musculares representaram aproximadamente 35% de todas as lesões. A incidência das lesões musculares foi 7,66 para cada 1.000 horas de jogo. Nas 3 temporadas (2016 a 2018), a mais comum foi a lesão muscular dos isquiotibiais (41,1%, 40,5% e 33,7%, respectivamente). Os laterais foram os mais acometidos, e a escala de severidade de lesão mais comum foi a moderada (8 a 28 dias). O momento da partida com maior incidência de lesões foi no período entre 61 e 75 minutos, com um índice de 19,9%, não havendo diferença estatística em relação aos demais períodos de jogo. Conclusão Houve uma incidência de lesões musculares de 7,7 lesões/1.000 h, e ocorreram predominantemente nos jogos em casa, em defensores (laterais e zagueiros), com idade média de 28 anos, envolvendo principalmente a musculatura isquiotibial, com tempo médio de afastamento moderado (8 a 28 dias).

Purpose To evaluate the incidence of anterior cruciate ligament (ACL) injuries in male athletes from professional soccer clubs over two consecutive seasons (2018-2019) with a sub-analysis based on age category: under-13 (U-13), under-15 (U-15), under-17 (U-17), and under-20 (U-20) years. Methods A total of 17,108 young male soccer players were retrospectively reviewed from sixty-three professional clubs in the four highest Brazilian soccer divisions. Data regarding the number of athletes and the number of ACL injuries conirmed by magnetic resonance imaging (MRI) exams in the 2018 and 2019 seasons were collected. Incidence of ACL injury were compared by season, age category (under-13; under-15; under 17; and under-20), demographic region, and club division. Results Clubs from all regions of Brazil participated in the study. A total of 336 primary ACL injuries were diagnosed over the two seasons (8,167 athletes during the 2018 season and 8,941 athletes during the 2019 season) among all athletes, which corresponds to 2% of the included athletes. There were 11 cases (0.3%) in the under-13, 53 cases (1.3%) in the under-15, 107 cases (2.5%) in the under-17, and 165 cases (3.8%) in the under-20 age category. There was a higher incidence of ACL injury in the older age groups (p < 0.001). Conclusion A total of 336 ACL injuries were identiied in 17,108 youth soccer players from 63 professional clubs with an overall incidence of 2% over 2 seasons of competition. ACL injury rate ranged from 0.3% to 3.8% and was higher in the older and more competitive club divisions. Level of evidence IV.
