External sagittal plane muscle moments generated by their contributions to the ground reaction forces over the stance phase. Since the muscle forces and kinematics are symmetrical, the muscle contributions to angular momentum are identical for both legs, and therefore the results from only one leg are shown. Positive values indicate the muscle is generating backward angular momentum, negative values indicate the muscle is generating forward angular momentum. Blue dashed lines are the contributions from the horizontal ground reaction force, red dotted lines are the contributions from the vertical ground reaction force. Solid black lines (Net) are the summed contribution from the horizontal and vertical components. All other muscle contributions were small and not shown.
