Abstract
While jumping is a fundamental movement skill, its coordination, especially at submaximal heights, is understudied. The purpose of this study was to use ground reaction force and 3D motion capture to understand how participants’ (n = 16, age = 23.0 ± 3.60 years) coordination patterns change when performing countermovement jumps to multiple heights (25%, 50%, 75%, 100%) across three phases of the jump (unweighting, eccentric, concentric) using modified vector coding. With increasing jump heights, anti-phase coordination of the thigh-pelvis segment couple in the unweighting phase increased (F = 17.05, p < 0.001), while thigh-leading coordination decreased (F = 17.06, p < 0.001). This finding, along with multiple significant coordination pattern changes in the eccentric phase of the jump, creates a framework for improved performance cueing and rehabilitation.
