✓ Correct answer: C. Pelvic drop Answer: Pelvic drop If the gluteus medius of the supporting leg is weak during a single-leg hop assessment, the most likely compensation is a pelvic drop. The gluteus medius is a key muscle responsible for stabilizing the pelvis during single-leg movements. Weakness in this muscle results in inadequate stabilization, causing the pelvis on the non-supporting side to drop lower than the supporting side. This compensation can lead to further issues such as poor lower limb alignment, which may increase the risk of injury. Identifying this weakness allows fitness professionals to develop specific exercises to strengthen the gluteus medius and improve overall movement quality.
