Abstract
CONTEXT: Injuries are a major adverse event in a soccer player's career. Reducing injury incidence requires a thorough knowledge of the epidemiology of soccer injuries. OBJECTIVE: To investigate the incidence and characteristics of injuries in the Dutch premier soccer league. DESIGN: Cohort study. SETTING: The Dutch premier soccer league. PATIENTS OR OTHER PARTICIPANTS: During the 2009-2010 soccer season, a total of 217 professional soccer players from 8 teams were prospectively followed. MAIN OUTCOME MEASURE(S): The medical staff recorded time-loss injuries, including information on injuries (ie, type, body part, duration) and exposure data for training sessions and matches. RESULTS: A total of 286 injuries were recorded, affecting 62.7% of the players. The overall injury incidence was 6.2 injuries per 1000 player-hours, 2.8 in training sessions and 32.8 in matches. Most of the recorded injuries were acute (68.5%). Eight percent of the injuries were classified as recurrent. Injuries were most likely to be located in the lower extremities (82.9%). Injury time loss ranged from 1 to 752 days, with a median of 8 days. Knee injuries had the greatest consequences in terms of days of absence from soccer play (on average, 45 days). The most common diagnosis was muscle/tendon injury of the lower extremities (32.9%). CONCLUSIONS: Injury risk in the Dutch premier soccer league is high, especially during matches. Preventive measures should focus on the most common diagnoses, namely, muscle/tendon injuries of the lower extremities.
