The purpose of this study examined the ability to predict previous knee and thigh injuries in athletes by assessing allometrically scaled ratios of average power and peak power results from VJ (vertical jump) and SLJ (standing long jump) testing using ROC curves. The strength and conditioning testing data and medical records of 26 female NCAA-I from soccer and volleyball teams were examined. Data examined included isokinetic knee flexion and extension, VJ power, and SLJ power outputs. Previous thigh or knee injury was compared to scaled average power ratio, peak power ratio, and calculated z-scores for average power ratio and peak power ratio. The use of AUROC to assess power output from the performance tests of the VJ and the SLJ to determine injury risk poorly predicts the possibility of a previous knee or a thigh injury.
