The purpose of this study was to validate a previously proposed cutoff for identifying the risk of sports injuries, based on the “ability to relax” component of a psychological competitive abilities measure. Validity was examined among male university athletes participating in individual sports (Study 1) and university tennis players who were screened for low physical injury risk using the Functional Movement Screen (FMS) (Study 2). Study 1 included 141 athletes participating in individual sports, and Study 2 included 29 tennis players with low physical injury risk. In both studies, injury occurrence was significantly associated with screening classification. In Study 1, the effect size was small (φ=.18), with a sensitivity of 46.7％ and a specificity of 71.9％; in contrast, in Study 2, which considered physical factors, a medium effect size was observed (φ=.41), and accuracy improved (sensitivity 55.0％, specificity 88.9％). These findings indicate that the proposed cutoff is effective for assessing injury risk among athletes in individual sports, and that accuracy is enhanced when physical factors are considered. In applied sports settings, a staged approach combining physical screening with psychological assessment may be effective for injury prevention.
