Energy is equal to to force times distance. The amount of force you can apply to an already near peak speed is low, and the distance you are applying the force over is very short, so yes -- we're typically talking under 1%.
Note that you can achieve acceleration immediately before impact via a whip crack energy transfer through the wrist, but this has very little to do with muscles. In addition, you can push the target
after the initial impact, but while that is relevant to knockback, and to the injury from a stabbing weapon that has penetrated armor, it has negligible effect on armor penetration.
