Example individual trial demonstrating sagittal plane CoM positions for criterion (cyan), unfiltered (green), low-pass filtered (red) and Kalman smoothed (blue) data during sprinting. Shaded areas depict the left foot (red shading) and right foot (green shading) stance phase. Footfall events were computed from marker-based foot kinematics [31]. OpenPose joint centre reconstructions (top) at touch-down and toe-off events are overlaid for context.
