Figure 4. (a) Chest and hip-joint angles. Dashed and solid thick lines respectively show the mean values during the right and left turns. The thin line shows the range of 1 SD centered on the mean. The LW10-2/11 and LW12-2 skiers show marked differences in the amounts of joint angle displacement and the maximum joint angle. Owing to the inability of the hip joints to perform voluntary flexion/extension, the variances of the hip flexion angle were smaller than those of the other joint angles in the LW10-2/LW11 skier. The asterisk indicates a significant difference between the right and left turns. (b) Edging angle. The chest lateral flexion and the edging angle showed similar trend.
