Please Scroll Down to See Forums Below You can! Keep lifting explosively and you can convert some slow twitch fibers to fast. At least that's the theory. Studies have shown the opposite to be true. Where long distance runners have had fast twitch fibers converted to slow. I don't know if there have been studies showing the converse to be true but it is assumed to be.

Oh crap...... I want a study, this would be about the most revolutionary news in the world of weightlifting!!
lol Deciever, I did a lot of research on this a few months back and read a couple physiology books (or tried). Glad I could help Cubanito.

Fast Twitch vs. Slow Twitch
I don't believe it's possible to convert slow twitch muscle fibers to fast twitch muscle fibers and vice versa. I do believe however that each muscle fiber can be maximized dependant upon training technique. George Halbert is one of the all-time best benchers ever and I'm willing to bet he is blessed genetically with an abundance of fast twitch muscle fibers in the pressing muscles (George is explosive as Hell). This is not to say that his ability is solely genetic. He has simple taken his genetics to another level by training intelligently and more intensely than 99% of the lifters competing today. You are what you are; and each has to do the best they can with what they are given. The important thing is to maximize one's own potential.
I can do 80% of my 1-max rep on bench about 5-7 times so I think I'm average.

Athough my statement wasn't completely accurate, the link below does show something can be done about the percentage of each type of fiber by the way you train.

Here is something else I came across.

In "Power-A Scientific Approach", Dr. Fred Hatfield on page referring to a paper by Armstrong in 1987 states:
"The mechanisms by which power,size, and strength are reduced as a result of endurance training most probably are mechanical destruction of existing white (fast-twitch) fibers, their replacement by red (slow-twitch) fibers, and enzymatic and neuromuscular changes more apropriate for slow, endurance types of movements".
"The mechanisms by which power,size, and strength are reduced as a result of endurance training most probably are mechanical destruction of existing white (fast-twitch) fibers, their replacement by red (slow-twitch) fibers, and enzymatic and neuromuscular changes more apropriate for slow, endurance types of movements".
perhaps this means that instead of CONVERTING slow twitch fibers to fast twitch fibers, that instead a lifter can manipulate the types of new fibers created through the type of training he or she does. if you create more fast twitch, the ratio of fast to slow rises. but i don't think you can actually convert slow twitch to fast twitch. that's like converting hot dogs to twinkies... or something, hehe. 
just a thought.
