Abstract

Introduction:The purpose of this study was to compare hip muscle resistance training with and without feedback on the trunk, pelvis, and lower extremity motions in frontal and sagittal planes in active females with dynamic valgus.
Materials and Methods: Twenty-nine active females (mean age: 22.8± 2.4 years, height: 1.70±0.6 m, mass: 69±7.1 kg) were randomly assigned to a hip muscle resistance training with feedback (n=15) or a hip muscle resistance training (n=14) group. Both training programs lasted six weeks(3 sessions/week). Peak angles of lateral trunk flexion, hip flexion, knee flexion, and valgus during single-leg drop landing and single-leg vertical drop jump were assessed for all participants at baseline and six weeks post-trainings.
Results:A significant main effect of group(p <0.05) except for hip flexion during single-leg vertical drop jump(p>0.05) the and time×group interaction(p <0.05) except for non-dominant leg hip flexion during single-leg vertical drop jump (p>0.05) were found for all outcomes.
Conclusion:Hip muscle resistance training with feedback seem to be better at improving trunk, pelvis and lower extremity motions in frontal and sagittal planes compared to hip muscle resistance training, while no significant differences were observed for hip flexion during single-leg vertical drop jump between the two groups in active females with dynamic valgus.
