Researchers develop new method for analyzing whole-body coordination in sports motion

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a novel method called Complex Hilbert Principal Component Analysis (CHPCA) to analyze whole-body coordination in sports motion using markerless 3D pose estimation data. This technique segments motion phases automatically and extends analysis to body surface mesh vertices, representing kinematic chains as continuous phase fields. The framework reveals a trunk-anchored global phase architecture and quantifies functional asymmetries between preparation and execution phases, bridging kinematic and kinetic descriptions of movement.
