This case-study investigated the motor control strategies underpinning a world-record performance in short-duration, high-intensity rope skipping, focusing on control accuracy and temporal adaptations under extreme speed and fatigue. Methods included 3D motion capture, ground reaction force measurements, and biomechanical modeling. Biomechanical parameters were quantified to identify time-dependent changes and distinctive control strategies. Results demonstrated exceptional clearance accuracy, with left foot operating at mechanical limit and right providing a safety margin. Progressive adaptations of COG height and ROM reflected fatigue-related adjustments, revealing a three-phase adaptation model. Kinetic analyses indicated a functional division of labor, with left leg serving as the power limb and right as the timing limb. Kinematic findings further identified a hierarchical control strategy: trunk adjustments provided rhythmic scaffolding, left leg joints stabilized during contact, and right leg joints enhanced clearance mobility. These results illustrate how asymmetric, hierarchical coordination optimizes performance under extreme temporal and spatial constraints.
