Linear regression analyses of the relationship between tibialis posterior (TP) fascicle length change (%) and (A) pronation displacement, (B) normalised subtalar joint (STJ) supination moments (Nm∙Nm−1), (C) normalised (STJ) negative work (J (kg m)−1), (D) total TP muscle activation during the negative power period. Moments and work were normalised to body weight (N) and foot length (m). 95% confidence interval of the regression lines are shown as dashed lines.
