Fig. 5. Representative traces of position, velocity and acceleration in looped
take-off modes. Data are from 3D coordinates of the head. The lateral,
horizontal and vertical components are represented by a thin blue line, thick
red line and thick green line, respectively. Gray banding represents the
vertical (light gray) and horizontal (dark gray) acceleration phases. (A-C)
Anchored J-loop take-off. (D-F) Sliding J-loop take-off.
