This study used a prospective cohort design with 357 elite male youth football players (aged 10\u201018\u00a0years) assessed during the preseason period and then monitored during the season recording all non\u2010contact lower extremity injuries. Screening tests included single leg hop for distance (<jats:styled-content style=\"fixed-case\">SLHD<\/jats:styled-content>); 75% of maximum hop and stick (75%Hop); single leg countermovement jump (<jats:styled-content style=\"fixed-case\">SLCMJ<\/jats:styled-content>); and the tuck jump assessment (<jats:styled-content style=\"fixed-case\">TJ<\/jats:styled-content>).
