As roughly 48% of these cases result from non-contact mechanisms, they are potentially preventable through optimized diagnostic screening. Evidence strongly links restricted hip range of motion (ROM) and strength deficits to an increased injury risk. This project aims to (1) develop a rigorously validated diagnostic testing procedure by comparing different joint positions, movement velocities, and muscle contractions to establish a preventive \"gold standard\" screening battery. dditionally, (2) pilot targeted prevention interventions over a competitive season. Using a crossover design, the research evaluates three protocols: Strength-focused,Flexibility-focused:and control group. (3) Implement of a Centralized Injury Reporting System. Combining comprehensive diagnostic screening with these practical interventions will yield a powerful tool for clinicians and coaches to effectively reduce the incidence and burden of non-contact hip and groin injuries",[91],"Hip Injury","NOT_YET_RECRUITING","2026-04-06",{"date":95,"type":96},"2026-04-13","ACTUAL",{"date":98,"type":85},"2027-01-01",{"date":100,"type":85},"2031-12-31",{"name":5,"class":6}]
