A well trained fast twitch muscle fiber can restore itself rather quickly and be ready for the speed requirements of the athlete.
The strength exercise activates the fast twitch muscle fibers (responsible for explosive power).
Chief among these is a preponderance of natural fast twitch muscle fibers, which aid in quicker reaction times.
Ballistic training forces the athlete's body to recruit and trigger fast twitch muscle fibers.
Complex training activates and works the nervous system and fast twitch muscle fibers simultaneously.
The gastrocnemius is actually made up of fast twitch muscle fibers, which benefit more from heavy loads and low reps (6-8) on the standing calf raise.
Intermediate fibers, also known as fast oxidative-glycolytic fibers, are fast twitch muscle fibers which have been converted via endurance training.
This stimulates Type 1 slow twitch muscle fibers and type 2 a and b fast twitch muscle fibers.
The ACTN3 protein, a "speed gene" most common among persons of West African descent that renders fast twitch muscle fibers fast.
Our bodies have two types of fast twitch muscle fibers - fast glycolytic (FG) and fast oxidative glycolytic (FOG).
From a scientific perspective, this approach allows them to develop their fast twitch muscle fibers and short twitch muscle fibers, all the while performing an intense cardio-strength interval workout.
The MYLK2 gene expresses skMLCK more prevalently in fast twitch muscle fibers as compared to slow twitch muscle fibers.
On the other hand, the main difference between the slow twitch muscle fiber (Type I) and fast twitch muscle fiber (Type II) has the same theory of the size deviations.
Fast twitch muscle (as compared to slow twitch muscle) operates using anaerobic metabolic systems, such that any recruitment of fast twitch muscle fibers leads to increased anaerobic energy expenditure.
Different muscle fiber types -slow twitch muscle fibers, oxidative muscle fibers, intermediate twitch muscle fibers, and fast twitch muscle fibers - release different clusters of myokines during contraction.
Fast twitch fibers make up the power muscles and are red.
This is, however, accompanied by a lack of fast twitch fibers (panel F).
However, fast twitch fibers fire more rapidly and generate more force.
They are a balance between the fast twitch fibers and the slow-twitch fibers.
Slow twitch muscles fire more slowly than fast twitch fibers, but are able to contract for a longer time before fatiguing.
This form of intense training can teach slow twitch muscle fibers to perform like fast twitch fibers.
Some authors define a fast twitch fiber as one in which the myosin can split ATP very quickly.
Type II-b fibers are fast twitch fibers.
In contrast, if the process was reversed, the fast twitch fiber performed as a slow twitch fiber as well.
Fast twitch fibers contract quickly and powerfully but fatigue very rapidly, sustaining only short, anaerobic bursts of activity before muscle contraction becomes painful.
During transition, the fast twitch fibers may increase in size, and gradually change into the slow twitch fibers exhibiting regular size.
These fibers are slightly larger in diameter, have more mitochondria as well as a greater blood supply and more endurance than typical fast twitch fibers.
Slow twitch fibers are more efficient in using oxygen to generate energy, while fast twitch fibers are less efficient.
Muscles are predominantly powered by the oxidation of fats and carbohydrates, but anaerobic chemical reactions are also used, particularly by fast twitch fibers.
Fast twitch fibers and slow twitch fibers are also called white muscle fibers and red muscles fibers, respectively.
It is thought to have a preferential beneficial effect on the slow twitch muscle fibers (as opposed to the fast twitch fibers used in sprint interval training).
Diminution of fast twitch fibers We also studied histochemical staining (type II and type I fibers) along with protein p27 expression.
MyoD expression is a key transcription factor in fast twitch fibers which is inhibited by NFATc1 in oxidative fiber types.
Studies have linked the fiber twitch type with ACTN3, i.e. fast twitch fiber abundant individuals carry the non-mutant gene version.
ACTN2 is expressed in all skeletal muscle fibers whereas ACTN3 is expressed only in fast twitch fibers.
The fast twitch fibers rely on a well-developed, short term, glycolytic system for energy transfer and can contract and develop tension at 2-3 times the rate of slow twitch fibers.
If you train a fast twitch fiber to do a lot of endurance work, it will eventually get a lot better, but it will never be as good as a slow twitch fiber."
Most people have about equal amounts of two types of fibers - slow twitch fibers, which are best for endurance events like marathons, and fast twitch fibers, which are best for sprints.
These observations indicate that an increase in cytoplasmic p27 staining may accompany normal female aging (age 49), along with the diminution of fast twitch fibers in otherwise normal muscles, and without manifestation of PFD.
Individuals with a high proportion of type I slow twitch muscle fibers will be relatively weaker than a similar individual with a high proportion of type II fast twitch fibers, but would have a greater inherent capacity for physical endurance.
