This study examined the relationship between hip strength and hip, pelvis, and trunk kinematics in healthy runners. Whole body kinematic data were collected while subjects ran in the laboratory. Isometric hip abduction, flexion, external rotation, and internal rotation torques were measured bilaterally using a dynamometer. Subjects were divided into strong and weak groups for each muscle strength parameter. Differences in hip, pelvis, and trunk motion were then examined using independent sample t-tests. Pearson correlation coefficients were used to assess these relationships for all subjects. Most notably, runners with weak abductors displayed greater hip adduction and pelvic rotation compared to the strong abductor group, while runners with weak external rotators displayed greater trunk rotation compared to the strong external rotator group. Moderate, negative correlations were observed for the above relationships. While data from this study help clarify the relationship between hip strength and running kinematics, no causal conclusions can be made.
