Youth participation in tackle football is increasing each year. Late maturation has been implicated as a risk factor for injury. Percentage of predicted adult stature derived from the Khamis and Roche [KR](1994) non-invasive method of adult stature prediction has been proposed as an alternative to invasive measures of maturity. Percentage of predicted adult stature remains untested as a maturity indicator in youth football players. The purpose of this study was to determine the validity of percent of predicted adult stature in youth football players, and to examine maturity as a risk factor for injury in the same population. There were 779 youth football players in grades fourth through eighth involved in the injury analysis study and a subset of 64 participated in the validation of the non-invasive method of maturity estimation. Partial correlations controlling for chronological age revealed that the KR percent of predicted adult stature was moderately, but significantly related to skeletal age (partial r, adjusted for CA, = 0.54; p < .001). Injury analysis revealed that 284 players accounted for 474 injuries and 26565 exposures. Players were twice more likely to be injured in games than in practices and 1.4 times more likely to suffer a non-time-loss injury. Risk factor analysis revealed that maturity was not a risk factor for injury. Stature and previous injury were significant risk factors for injury.
