Does the height of someone who plays soccer affect the strength of their kick?

Yes and no. The height determines ones leg length and leg weight. Theoretically, a longer leg would be heavier, causing it to add more velocity and yes strength to the kick. However the only thing that deters this is the fact that it takes longer for one with a long leg, to wind up and kick the ball. Meaning a full swing during game time for a short person is less than a full swing for a tall person
