Figure 3. Stick pictures from the right and back sides of a ski. Stick pictures during the right and left turns are overlaid. The thick line in the figures in the lower panel shows the angulation at the chest joint. Both 0% and 100% of time indicate the switching instant of the right (left) turn. The LW10-2/11 and LW12-2 skiers showed a marked difference in trunk movement in the sagittal plane.
