EXAMINING THE CORRELATION BETWEEN HIP ADDUCTOR MUSCLE STRENGTH, CORE STABILIZATION, AND LOWER EXTREMITY PERFORMANCE IN HEALTHY INDIVIDUALS

Purpose: This study aimed to investigate the correlation between hip adductor muscle strength and endurance, core stabilization, and lower extremity performance. Methods One hundred thirty-three healthy individuals were included in the study. Bilateral hip adductor muscle strength was evaluated with a compression test by using a sphygmomanometer, and endurance was evaluated by the number of hip adduction repetitions for each extremity performed in the side-lying position in one minute. Core stabilization was evaluated by the endurance of the trunk muscles (the time of maintaining the flexion of the trunk 60 degrees, the lateral bridge position, and the trunk extension against gravity). Lower extremity dynamic balance (Y balance test) and performance (single-leg and triple-crossover hop test) were also evaluated. Results A positive and moderate correlation was found between hip adductor muscle strength and endurance of nondominant (r=0.529, p<0.001) and dominant (r=0.355, p<0.001) trunk lateral flexors on the lower extremity side, dominant single-leg hop test (r=0.314, p<0.001), and dominant (r=0.362, p<0.001) and nondominant (r=0.331, p<0.001) triple-crossover hop test. A negative and low level of correlation was found between hip adductor muscle strength and dominant (r=-0.235, p=0.007) and nondominant (r=-0.244, p=0.005) Y balance test total scores, and dominant (r=-0.167, p=0.055) and nondominant (r=-0.186, p=0.032) Y balance test posteromedial scores. Conclusion Hip adductor muscle strength and endurance were significantly correlated with core stabilization, lower extremity dynamic balance and performance, and hip adductor muscle strength, balance, and performance test scores were affected by gender.
