Fast Twitch / Slow Twitch: Which Twitch Are You?

Posted Feb 15 2010 12:00am
You have become hooked on running. You were born to run. But were you born to run fast or far?

Sprinters and distance runners are obviously different, but what causes one to be so fast and the other to have so much endurance?

The muscle has different types of fibers which determine whether you move quickly. If you have a high percentage of fast-twitch muscle fibers, you will be a fast runner. These types of cells burn sugar and fire very quickly and powerfully. The downside is that they burn fuel very quickly and are not resistant to fatigue. Slow-twitch muscle fibers tend to burn fat and fire repeatedly over a longer period of time.

There are ways to test the muscle fiber to see if it has more fast twitch or slow twitch muscle fibers, but they can be painful and are reserved for scientific study. For those with predominantly fast-twitch muscle fibers, there are ways to train the muscle to act in a slow-twitch manner and burn more fat than sugar, thus increasing endurance.
