everyone either has fast twitch fibres/slow twitch fibres in the muscles.. if your a fast runner you obviously have more fast twitch fibres, meaning you'll be able to move your leg muscles quicker, so i suppose when your freestyling & if you have lots of fast twitch fibres, i guess you could say you could get your leg around the ball quicker then other freestylers who don't have as many fast twitch fibres.
meh, just a thought.
