Underlying trends elucidated by preference. Normalization of stiffness values by preference highlights underlying relationships between kinematic symmetry and VSPA stiffness, which are obscured when stiffness is normalized by weight. A Cross-leg RMS diff. ankle angle versus preference-normalized stiffness. Intra-subject averages for each speed and stiffness are plotted as individual points. Light lines show a second-order fit to all pooled intra-subject averages at each speed. B Cross-leg RMS diff. ankle angle versus weight-normalized stiffness.
