Relationship between the knee valgus moment and the hip abductor and adductor activity during single-leg landing

To reveal the relationship between the knee valgus moment (KVM) and the hip abductor and adductor activity during single-leg landing. A cross-sectional study. Laboratory-based, between April 2020 and May 2021. Thirty female collegiate athletes. KVM, hip adduction angle, hip internal rotation angle, knee valgus angle (KVA), gluteus medius muscle activity, adductor longus muscle activity, adductor longus to gluteus medius activity ratio (ADD/GMED), and vertical component of the ground reaction force (vGRF). Stepwise multiple regression analysis was performed. KVM was significantly positively associated with KVA (β = 0.613, p
