What's the difference between fast twitch muscle fibers and slow twitch???

[Salahudeen]

which is better to have?? and is it possible to change muscle fibers from fast twitch to slow twitch??

and does the type of muscle fibre twitch impact upon the way you should train the muscle??

Also I've noticed people who don't have big muscles are sometimes stronger than people who have massive muscles.

is this to do with fast twitch and slow twitch??
