Gear increasing fast twich fibers

[100m champ]

is there any gear out there increasing fast twich fibers?

Gear in general will increase fast twich fibers,but your looking in the wrong area.It`s all to do with the type of training you do.Muscle fiber type appears to play an important role in determining success in some sports. Successful distance runners have a high proportion of slow twitch muscles (percent slow twitch fibers is highly related to maximum oxygen consumption). Sprinters have a predominance of fast twitch muscles. Several studies have shown that a high content of fast twitch fibers is a prerequisite for success in progressive resistance training. This is understandable, as the fast twitch fibers experience selective hypertrophy as a result of high resistance, low repetition exercise.

I have to agree with the above post. Your best way of increasing that type of fiber is a more explosive training. I have read this many times before but I do not have any links or books that I can think of right now. I'm pretty sure it would be some sort of plyometric taining that athletes usually use.
