Strength and power exercise like weight lifting requires the explosive release of energy yielded by fast-twitch muscle fibers. Slow-twitch muscles are involved in endurance activity.

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 are the three types of muscle fibers?
The three type of muscle fibers are fast-twitch, slow-twitch, and hybrid.
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
What is it called when white muscle fibers that contract quickly?
Fast-twitch muscle fibers.
What muscle fibers have fast contractions and a high level of glycogen stores?
fast-twitch fibers
What is true about fast-twitch muscle fibers?
They contract very quickly
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.
Fast twitch fibers are also called?
Fast twitch fibers are also called Type II muscle fibers due to their quick and powerful contractions. These fibers are typically used for explosive and high-intensity activities such as sprinting or weightlifting.
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.
What are slow twitch muscle 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.
How can you get more fast twitch muscle fibers?
There is no proven way to gain muscle fibers. Some research has shown that through intense explosive exercises VERY FEW slow twitch fibers will be converted to fast twitch. Other research, shown only in ANIMAL testing, has suggested that super high weight and low rep (1-3) will actually CREATE NEW fast twitch muscle fibers. But your pre-existing fast twitch muscle fibers can gain massive increases in size through explosive exercises. Examples of these exercises would be sprints, high weight low rep resistance training, and Olympic lifts. Remember, there is no proven way for HUMANS to actually gain new muscle fibers.
