What is the difference between skeletal muscle Fibrs types?

Skeletal muscle fibers can be categorized into two types: slow-twitch (Type I) and fast-twitch (Type II). Type I muscle fibers are more efficient over long periods of time. They are mainly used for postural maintenance (such has holding the head upright), or endurance exercises (like marathon running).
