Recent prospective cohort studies have reported preseason functional performance test (FPT) measures and associations with future risk of injury; however, the findings associated with these studies have been equivocal. The purpose of this study was to determine the ability of a battery of FPTs as a preseason screening tool to identify female Division III (D III) collegiate athletes who may be at risk for a non-contact time-loss injury to the lower quadrant [LQ = low back and lower extremities]. One hundred six female D III athletes were recruited for this study. Athletes performed 3 FPTs: standing long jump (SLJ), single-leg hop (SLH) for distance, and the lower extremity functional test (LEFT). Time-loss sport-related injuries were tracked during the season. Thirty-two (24 initial and 8 subsequent) time-loss LQ injuries were sustained during the study. Ten of the 24 initial injuries occurred at the thigh and knee. At-risk athletes with suboptimal FPT measures (SLJ ≤ 79% ht; (B) SLH ≤ 64% ht; LEFT ≥ 118 s) had significantly greater rates of initial [(7.2 per 1000 athletic exposures (AEs)] and total (7.6/1000 AEs) time-loss thigh or knee injuries than the referent group (0.9/1000 AEs; 1.0/1000 AEs respectively). At-risk athletes were 9 times more likely to experience a thigh or knee injury (OR = 9.7, CI: 2.3, 39.9; p = 0.002) than athletes in the referent group. At-risk athletes with prior history of LQ sports injury and lower off-season training habits had an 18-fold increased risk of a time-loss thigh or knee injury during the season (AOR = 18.7, CI: 3.0, 118.1; p = 0.002). This battery of FPTs appears useful as a tool for identifying female D III athletes at risk for a LQ injury; especially to the thigh or knee region.
