Background: Epidemiologic research to learn the incidence, type, location, and severity of female soccer injuries and the risk factors for sustaining a sport injury is the first step in developing preventive policies. The aim of this study was to analyze the incidence of injuries in the population of female soccer players in Spain.Methods: The injuries incurred by 25,397 female soccer players were registered by the medical staff of the Spanish Football Federation during 1 season. A standardized medical questionnaire was used to classify the injury according to type, severity, location, and injury mechanism. A total of 2108 injuries was reported with an incidence of 0.083 injuries per player per season. Most injuries were in the lower limbs(74.0%), mainly affecting knee(30.4%) and ankle joints(17.9%).Results: The proportion of injuries derived from contact with another player was higher during matches(33.7%) than during training(11.4%;p < 0.001). Noncontact injuries were classified as severe more frequently than were contact injuries(51.0% vs. 42.6%; p < 0.001). A higher incidence of injury was found in adult soccer players(≥18 years) vs. their counterparts younger than 18 years(0.094 vs. 0.072 injuries per player per year, respectively; p < 0.001). There were no differences between age groups in any other injury variable(e.g., type, mechanism, location, or severity; p > 0.05).Conclusion: Most female soccer injuries were located at the knee and ankle; the injury mechanism determined the playing time lost; and the player's age did not affect injury characteristics. 展开更多
