  ABSTRACT: To better understand interlimb coordination during the double stance phase at fast walking speeds, we analyzed ground reaction forces generated by the leading and trailing limbs during the double stance phase at multiple speeds. Ground reaction forces were recorded during the double stance phase at slow, self-selected, and fast walking speeds in eleven healthy volunteers. We calculated the instantaneous phase of the ground reaction forces for the vertical and anterior-posterior components, and then calculated the relative phase between the leading and trailing limbs for each component. For the vertical component, the relative phase showed a significantly lower value in the fast condition than in the other two conditions in the early-double stance phase (fast vs. self-selected, p
