No... fast twitch muscle is for explosive power. It is for bursts of speed as well. What it typically lacks is endurance- which is what slow twitch excels at.
If you wanted to do a type of workout that required a large number of reps in each set, then you are usually doing more slow twitch work than fast twitch. If you do the pyramid bench Rip described earlier, that would be more of a fast twitch routine.
In running, sprinters are pure fast twitch, whereas distance runners tend to be more slow twitch. This doesn't mean fast twitch athletes can't be distance runners; fast twitch can be taught to behave as slow twitch. What you can't really do is make slow twitch fast. To this extent, you are either born fast or you're not. Most people can train to excel at distance running, few people can be trained to excel at sprinting.
