Injuries in Youth Soccer During the Preseason

Objective:To evaluate injuries occurring during the preseason in youth soccer players. Design:Prospective cohort study over 1 preseason. Setting:2009-2010 preseason. Participants:Subjects were 912 youths aged 12 to 19 years. Assessment of Risk Factors:The club's medical staff prospectively recorded all injuries. A reportable injury was defined as by the consensus statement on soccer injuries. Estimated injury rates per 1000 hours of exposure during the preseason period were calculated. Main Outcome Measures:Injury rates (injuries per 1000 hours of soccer exposure) during preseason practices by age group, as well as prevalence, severity, and type of injuries. Results:Total incidence was 2.5 injuries per 1000 hours of exposure. Incidence of match and training injuries were 6.7 and 1.8 injuries per 1000 hours (P = 0.02), respectively. Injuries were sustained by 7.2% of players during the preseason, and 79% of the injuries involved the lower limbs, of which 23% were located to the thigh. Muscle strains and contusions were the most common injuries and external trauma the main cause. Conclusions:No age-related trend in the incidence of preseason injuries was found. During the preseason training period, athletic trainers should expect a majority of muscle strains, especially in the thigh region.
