Pearson's correlation coefficients between changes between trials in balance performance (COM mediolateral path length) and changes between trials in the contribution of the derivative of the angular momentum (Ḣ) to COM acceleration in the relative power between 2.5 and 4.5 Hz of the board angle and in the effects of the vestibular and visual manipulation on COM excursion. Pre 1-pre 2 refers to the differences between the 2 pretraining trials. Pre 2-post 1 refers to differences between the 2nd pretraining trial and the 1st posttraining trial. The dashed horizontal line indicates the threshold for significance at α < 0.05.
