Fig. 4

The correlations between VORT for the vertical CoM position and VUCM for the vertical swing foot position. The horizontal axes represent VUCM for swing foot position, and the vertical axes represent VORT for CoM position. Upper panels: the correlations in the Early-SS phase, Middle panels: the correlations in the Mid-SS phase, Lower panels: the correlations in the Late-SS phase. Statistically, significant correlations are shown with one star (p < 0.05). For abbreviation, see the caption for Fig. 2
