PURPOSE:This study investigated the association between the posterolateral hip strength and lateral functional performance in healthy young adults and whether this relationship differs between sexes. METHODS:Forty-eight healthy adults (19 male, 29 female; 18-34 years) without a lower extremity pathology were included.The posterolateral hip strength of the dominant limb was assessed using the Hip Stability Isometric Test (HipSIT) with a handheld dynamometer, and the results were normalized to the body mass.The lateral functional performance was evaluated using the Side-Hop Test (SHT), recorded as the time to complete 10 lateral single-leg hops over 30 cm.Sex differences were analyzed, and sex-specific correlations between the HipSIT strength and SHT time were examined using the Spearman coefficients. RESULTS: Men showed significantly greater normalizedHipSIT strength and faster SHT times than females (p < .05).
