Hip muscle strength and functional performance were assessed. Self-reported sport and recreation ability was quantified using the sports and recreational subscales from the International Hip Outcome Tool-33 (iHOT-Sport) and the Copenhagen Hip and Groin Outcome Score (HAGOS-Sport). Relationships were evaluated using regression models with sex and cartilage defects as potential effect modifiers. <\/jats:p><jats:p> RESULTS: There was a positive linear relationship between the one-leg-rise test and the iHOT-Sport subscale (\u03b2 = 0.61; 95% CI: 0.09, 1.14). A polynomial (concave) relationship was found between peak eccentric adduction strength and the HAGOS-Sport subscale (\u03b2 = \u221230.88; 95% CI: \u221257.78, \u22123.99). Cartilage defects modified the relationship between peak isometric adduction strength and HAGOS-Sport, with those with cartilage defects having a polynomial (convex) relationship (\u03b2 = 36.59; 95% CI: 12.74, 60.45), and those without cartilage defects having no relationship. <\/jats:p><jats:p> CONCLUSION: One-leg-rise performance and adduction strength were associated with self-reported sport and recreation ability, indicating a possible relationship between physical function, hip joint structure, and sport and recreation ability in football players with hip dysplasia.
