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 are the three types of muscle fibers?
The three type of muscle fibers are fast-twitch, slow-twitch, and hybrid.
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.
Twitch muscle fibers are used for prolonged activity and have?
____ twitch muscle fibers are used for prolonged activity and have ___ mitochodria. Slow; many
What are the kinds of aerobic respiration?
Slow twitch and fast twitch A muscle fibers.
What Type of Muscle Fibers are used in Badminton?
slow twitch and fast twitch
Which turkey meat is made of slow twitch muscle fibers?
Muscle fibers when cooked are dark meat.
What type of muscle fibers are found in higher proportion in weight lifters?
slow-twitch muscle fibers
Which muscle fibers are best suited for running a marathon?
Type I (red) muscle fibers, which have slow oxidative characteristics, are those primarily called on for long-distance running. These are more commonly referred to as 'slow-twitch' muscle fibers.
Can you convert swimming laps into walking steps?
no, within your muscles are slow and quick twitch muscle fibers, activities such as running and walking use quick twitch muscle fibers while swimming uses slow twitch muscle fibers
Slow twitch muscle fibers are resistant to what?
are very resistant to fatigue
What is the difference between fast twitch and slow twitch muscle fibers?
Fast twitch muscle fibers are Type II muscle fibers. These muscle fibers have high explosive power and are anaerobic. They have a fast contractile speed and can reach peak tension in 50ms. They have a high glycolytic capacity and have low to moderate resistance to fatigue. Their motor unit strength is high.Slow twitch muscle fibers are Type I muscle fibers. These muscle fibers have steady power and are aerobic. The have a slow contractile speed and needs 110ms to reach peak tension. They have a low glycolytic capacity and a high resistance to fatigue. Their motor unit strength is low.
What is a physical activity that is short explosive and depends solely on the enegry that is stored in a musle and not on oxygen intake?
You are thinking of muscle fibers types. Skeletal muscle fibers are grossly divided into two type; slow twitch (type I) and fast twitch (type II).Slow twitch fibers are capable of continuous extended contractions and therefore, do not fatigue quickly. Fast twitch fibers are used for short rapid bursts of energy and as such fatigue more quickly than slow twitch fibers.
