In professional male soccer, the risk of injury is a 1000 times higher compared to other occupations. Most injuries occur during matches. To prevent injuries in professional soccer matches, risk factors need to be identified that are specific to the sport. Purpose – The aim of the current study was to assess physical and tactical risk factors preceding an injury in a professional soccer match. Methods – Professional soccer players from 18 teams were studied in 234 matches. Injuries were identified based on video footage. Next, physical parameters as total distance (m), distance in speed zones (m) and number of sprints were investigated based on synchronized positional data. Tactical parameters included inter-team distances (m) in lateral, longitudinal and multidirectional directions and were calculated based on the centroids of the two teams. These physical and tactical risk factors were studied 5 minutes, 1 minute and 30 seconds prior to the moment of injury and compared to a data from matches where no injury occurred. Paired t-tests were performed to compare the activities between the time prior to the injury and the normative profiles. Results – Out of 45 captured injuries, 36 were contact injuries and 9 were non-contact injuries. Physical risk factors: Total distance, running distance and were significantly higher compared to the normative profiles in the 1 minute time window (p<.05). For the 30 seconds window also high speed and very high speed distance were significantly higher (p<.05). Tactical risk factors: Significantly smaller lateral, longitudinal and multidirectional inter-team distances were found in respectively all the time windows, compared to the normative profiles. For non-contact injuries, the longitudinal and multidirectional inter-team distances were significantly smaller compared to the normative profile over a 1 minute time window. Conclusion – These results suggest that physical and tactical parameters are risk factors for injuries in professional soccer matches.
