Background: Calf muscle fatigue has been shown to affect movement patterns and may contribute to increased injury risk, particularly in the knee joint. Objective: This study aims to investigate the effect of calf muscle fatigue on lower limb kinematics during cutting maneuvers in female athletes with and without dynamic knee valgus (DKV). Methods: This case-control study included female athletes with (n = 12) and without dynamic knee valgus (n = 12). The cutting maneuver kinematics were measured with 10 cameras motion analysis before and after calf muscle fatigue, which was induced using an isokinetic dynamometer through repeated maximal...
