RESUMO Objetivo: Testar a confiabilidade entre dois instrumentos com diferentes mecanismos de análise, seja por GPS (modelo GPSPORTS®) ou por análise de vídeo (InStat For Players®), relacionando os resultados de distância total percorrida e distância em alta velocidade ≥ 20km/h (Distância de Corrida de Intensidade Muito Alta, VHIR) durante partidas oficiais de futebol. Desenho do Estudo: Este é um estudo metodológico. Dados de 35 atletas de futebol profissional do sexo masculino, de todas as posições táticas foram incluídos. Idade 29,2 (± 4,8 anos) e gordura corporal 9,9 (± 1,7%), excluindo goleiros (102 análises individuais) foram coletados em jogos oficiais. Na análise dos dados, foram utilizados procedimentos de estatística descritiva para caracterizar a amostra e o coeficiente de correlação intraclasse (ICC) foi utilizado para verificar a concordância quanto à estabilidade e consistência interna dos testes com intervalos de confiança (IC) de 95%. Resultados: O ICC no caso da variável distância total percorrida foi significativo 0,914 (0,876; 0,941) e indicou concordância muito elevada, com o coeficiente de correlação linear indicando forte correlação positiva (p <0,001). O ICC para a variável VHIR não foi significativo, embora o coeficiente de correlação linear indique uma correlação positiva forte (p <0,001). Declaração de Relevância Clínica: Este estudo revela que há boa concordância na comparação de dois sistemas projetados para analisar as demandas de movimento de cada atleta profissional de futebol em relação à distância total percorrida. Nível de evidência I; Estudo metodológico - Investigação de um teste diagnóstico.

ABSTRACT Objective: To test the reliability between two instruments with different analysis mechanisms, either by GPS (model GPSPORTS®) or by video analysis (InStat For Players®), relating the results of total distance covered and distance at high speed ≥ 20km/h (Very High-Intensity Running Distance, VHIR) during official soccer matches. Study Design: This is a methodological study. Data from 35 male professional soccer athletes from all tactical positions were included. Age 29.2 (± 4.8 years) and body fat 9.9 (± 1.7%), excluding goalkeepers (102 individual analyzes) were collected in official matches. In the data analysis, descriptive statistics procedures were used to characterize the sample and the intraclass correlation coefficient (ICC) was used to verify the agreement on the stability and internal consistency of the tests with 95% confidence intervals (CI). Results: The ICC in the case of the total distance traveled variable was significant 0,914 (0,876; 0,941) and indicated a very high agreement, with the linear correlation coefficient indicating a strong positive correlation (p <0.001). The ICC for the VHIR variable was not significant, although the linear correlation coefficient indicates a strong positive correlation (p <0.001). Clinical Relevance Statment: This study reveals that there is good agreement in the comparison of two systems designed to analyze the movement demands of each professional soccer athlete in relation to the total distance covered. Level of Evidence I; Methodological Study - Investigation of a diagnostic test.

RESUMEN Objetivo: Probar la confiabilidad entre dos instrumentos con diferentes mecanismos de análisis, ya sea por GPS (modelo GPSPORTS®) y por análisis de video (InStat For Players®), relacionando los resultados de distancia total recorrida y distancia a alta velocidad ≥ 20km / h (Distancia de carrera de muy alta intensidad, VHIR) durante los partidos oficiales de fútbol. Diseño del estudio: se trata de un estudio metodológico. En los partidos oficiales se recopilaron datos de 35 atletas de fútbol profesionales masculinos, de todas las posiciones tácticas. Edad 29,2 (± 4,8 años) y grasa corporal 9,9 (± 1,7%), excluidos los porteros (102 análisis individuales). En el análisis de datos, se utilizaron procedimientos de estadística descriptiva para caracterizar la muestra y se utilizó el coeficiente de correlación intraclase (CCI) para verificar la concordancia sobre la estabilidad y consistencia interna de las pruebas con intervalos de confianza (IC) del 95%. Resultados: El CCI en el caso de la variable distancia total recorrida fue significativa 0,914 (0,876; 0,941) e indicó una concordancia muy alta, con el coeficiente de correlación lineal indicando una fuerte correlación positiva (p <0,001). El CCI para la variable VHIR no fue significativo, aunque el coeficiente de correlación lineal indica una fuerte correlación positiva (p <0,001). Enunciado de relevancia clínica: Este estudio revela que existe un buen acuerdo en la comparación de dos sistemas diseñados para analizar las demandas de movimiento de cada deportista de fútbol profesional en relación con la distancia total recorrida. Nivel de evidencia I; Estudio Metodológico - Investigación de una prueba diagnóstica.

ABSTRACTObjective:To establish the injury profile of soccer players from a first division Brazilian soccer team. In addition, we investigated the association between the characteristics of the injuries and the player's age and position.Method: Forty-eight players from a Brazilian first division soccer team were followed during one season. Descriptive statistics were used to characterize the injury profile. Spearman's tests were used to verify the association between the number and severity of injuries and the player's age. Chi-square test was used to verify the association between type of injury and player's position. Fisher's exact test was used to verify the association between the severity of injuries and player's position.Results: The incidence of injuries was 42.84/1000 hours in matches and 2.40/1000 hours in training. The injury severity was 19.5±34.4 days off competition or training. Lower limb was the most common location of injury and most injuries were muscular/tendinous, overuse, non-recurrent, and non-contact injuries. Player's age correlated with the amount and severity of muscle and tendon injuries. Defenders had more minimal injuries (1-3 days lost), while forwards had more moderate (8-28 days lost) and severe injuries (>28 days lost). Furthermore, wingbacks had more muscle and tendon injuries, while midfielders had more joint and ligament injuries.Conclusion: The injury profile of the Brazilian players investigated in this study reflected regional differences in soccer practices. Results confirm the influence of the player's age and position on the soccer injuries profile.
