Because they have a faster release of energy which causes them to slow down quicker.
The twitch actually refers to the fatiguability of the fiber. So, fast twitch do produce more force, but tire 'fast'er than slow twitch, which are 'slow'er to fatigue

What else can I help you with?
Are there fast twitch muscles in your legs?
There are fast twitch muscles fibers in all of your muscles, especially in your legs.
Individuals with a large percentage of fast twitch muscle fibers will generally?
People who possess a high percentage of fast twitch muscles will generally be quicker, faster, and able to jump higher than people with a lower percentage of fast twitch muscles.
What is the difference between fast twitch and slow twitch muscles?
Fast-twitch fibers can deliver a quick burst of power.Slow-twitch fibers can maintain a contraction for a longer time! -Apex :]
What is the role of slow muscle fibers and fast muscle fibers in the response of a muscle to different types of exercise?
There are two broad types of voluntary muscle fibers: slow twitch and fast twitch. Slow twitch fibers contract for long periods of time but with little force while fast twitch fibers contract quickly and powerfully but fatigue very rapidly.
What fibers are slow twitch fibers?
Our bodies are made up of different types of muscle fibers, all of which rely on different energy systems. Slow twitch fibers, as the name suggests, contract more slowly than fast twitch muscle fibers and they can contract for a longer period of time. We often call these 'endurance' muscles because they're great for aerobic activities that require endurance like running, cycling and swimming. In general, many of us will have about 50% slow twitch fibers and 50% fast twitch fibers, although it will differ between individuals. Successful long-distance runners will often have more slow twitch fibers while sprinters or bodybuilders will often have more fast twitch fibers. Strength training in different rep ranges (from 4-16) will allow you to work different muscle fibers and energy systems in your body.

What is it called when white muscle fibers that contract quickly?
Fast-twitch muscle fibers.
Do all human muscles contain fast and slow muscle fibers?
Yes Such as in weight traning if you train your fast twitch you will recover faster but fast is more muscle strength not really size if your looking for size in muscles go with slow twitch
What is true about fast-twitch muscle fibers?
They contract very quickly
Is true about fast twitch muscles?
They contract very quickly
What is true about twitch fast muscle fibers?
They contract very quickly
Which kind of muscles fibers enable the muscles to exert force for a long period of time?
Slow Twitch (:
