Context: Running related injury occurs frequently in collegiate cross-country runners. Hip strength is one factor that may be important in the rehabilitation and training of cross-country runners. However, no normative values exist to inform these strategies.

Objective: Establish normative values for hip abduction and external rotation isometric strength in collegiate cross-country runners and explore the association between strength and previous injury.

Design: Mixed methods using descriptive epidemiology and retrospective cross-sectional designs.

Setting: University Laboratory

Patients or Other Participants: Eighty-two NCAA Division III cross-country runners (38 males, 44 females) participated in this study.

Main Outcome Measure(s): Isometric hip strength and reported injury

Results: Males demonstrated greater absolute hip strength than females. Measures of hip strength were not different between sexes when normalized to height and mass. Hip abduction asymmetry was associated with previous injury in males. A combination of at least one leg with hip abduction weakness and bilateral external rotation weakness was associated with previous injury in females.

Conclusions: Knowledge of normative values of hip strength may help inform rehabilitation strategies in collegiate cross-country runners. Males and females may demonstrate differing strength profiles following running related injury.
