Jones S, Almousa S, Gibb A, et al. - Using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, researchers analyzed and summarized published scientific data on high-level youth football injury characteristics and calculated the risk of injury sustained during the typical season. Of the 1,346 studies identified, 23 met the criteria for inclusion. Data reported that the likelihood of sustaining a time-loss injury during a high-level youth season ranged between < 1% and 96% for under 9- to under 16-year age groups and 50% and 91% for under 18- to under 21-year age groups. Findings suggested that high-level youth players lose large portions of seasonal development as a result of injury, with players apparently suffering from long absences from training and matches, thus affecting health and well-being and possibly burdening club/parental finances and healthcare systems.
