And remember Super-HEavy weight lifters lift far more than 130lb weight lifters.
You can actually turn on slow twitch to be semi-fast twitch with training. And you can enlarge fast twitch fibre too.
No offense, but this is my area of expertise. A few corrections:
1. Superheavy lifters do lift more than small lifters, obviously. However, they do NOT lift PROPORTIONALLY more. In fact, the strongest pound-for-pound lifter WAS a bulgarian called "The Pocket Hercules".
2. Whether Lennox is more explosive than Marciano is unknown and highly debatable.
3. You absolutely cannot, under any circumstance, turn a slow-twitch fiber into a fast-twitch fiber. The mitochondria of the fiber types is different, and it can no more be done than you training your iris to be green and not brown. You can elevate in a minimal way the PERCENTAGE of fast-twich fibers to a very, very minimal extent through training. A person with a naturally low percentage of fast fibers will always have a naturally low percentage of fibers, regardless of training. Fast twich fibers are NOT thick-bundle fibers (to use a lay term). One other interesting factor that plays a part is reconditioning of the Golgi reflex, which can inhibit or excite greater groups of muscle recruitment, which allows slower fibers to ACT like fast fibers due to higher collective recruitment under stress.
I hope that clears it up a bit.
