During the Single-leg Squat assessment, the compensation of "hip drop" can be attributed to overactivity of which muscle?

The compensation of "hip drop" during the Single-leg Squat assessment indicates that there is a lack of stability in the hip on the side of the stance leg. This specific compensation can be attributed to overactivity of the adductor complex on the same side as the stance leg. When the adductors are overactive, they can pull the pelvis down on the stance leg, causing the hip to drop toward the ground rather than maintaining a level position.

In this scenario, the adductor complex's role is crucial as it assists in stabilizing the pelvis, especially during single-leg movements, where balance and control are key. If the adductors are overly dominant or tight, they can compromise the alignment and function of the hip and pelvis, leading to the observed compensation.

Understanding this relationship is important for corrective exercise strategies, as addressing overactivity in the adductor complex may help to improve pelvic stability and alignment during lower body movements.
