Improving running performance is multi-faceted; the aim of this article is to focus on exercises related to fast twitch muscle fibers and explains a general overview of their function.
Fast-Twitch Muscle Fibers:
Type II fibers are involved in any activity that includes a quick explosive movement or the rapid development of power. Most common applicable example would be football players and track and field athletes. Type II fibers develop more power then Type I or slow twitch muscle fibers because the Type IIx fiber can contract 10 times faster than the Type I fiber. The more adept you become at recruiting your Type II fibers; the more power you can develop. This leads to faster sprint times and decreased mile times for more focused short distance runs.
