Fast-twitch fibers can be further classified into (1) fast-twitch IIa - fast oxidative glycolytic, because they use oxygen to help convert glycogen to ATP, and (2) fast-twitch type IIb - fast glycolytic, which rely on ATP stored in the muscle cell to generate energy. During aerobic activities of progressively greater intensity; changes in the pattern of muscle fiber type recruitment occur. In general, this progression moves from Type I oxidative fibers, to Type IIa fast twitch, fatigue resistant fibers, and finally to Type IIx fast twitch fibers. These two types of fast-twitch fibers also differ from each other, with Type IIa fibers displaying some similarities with the slow-twitch fibers. Type IIa fibers can produce energy through both glycolytic AND oxidative pathways which make them slightly more fatigue resistant than the Type IIb fibers. Type IIa, red, fast-twitch fibers in essence contain attributes of both these types.

Type IIA fibers, or fast oxidative fibers, are used more during sustained power activities such as sprinting 400 meters or doing repeated lifts with a weight below maximum (but not with very light weights). They contain very large amounts of myoglobin, very many mitochondria and very many blood capillaries. The two types of fast twitch muscle fibres are: Type 2A also known as fast oxidative-glycolytic Type 2B or fast glycolytic Fast oxidative/glycolytic fibers provide a faster twitch and larger force while still maintaining resistance to fatigue, great for extended sprinters such as a 400 meter run specialist. Lastly, fast glycolytic fibers provided the largest force and fastest twitch speed but are highly fatigue-able and are reserved for high-intensity bursts such as a short sprint or maximal lifts. 2020-06-15 · Fast-twitch muscle fibers are one of two types of skeletal muscle fibers, in addition to slow-twitch muscle fibers. Fast-twitch muscles are responsible for high-intensity work like heavy lifting 2019-01-01 · Human skeletal muscle is an extremely heterogeneous tissue that is composed of type I (slow twitch) and type II (fast twitch) muscle fibers.

Lastly, fast glycolytic fibers provided the largest force and fastest twitch speed but are highly fatigue-able and are reserved for high-intensity bursts such as a short sprint or maximal lifts. 2019-01-01 Slow oxidative (SO) muscle fibers: A. Are intermediate types between fast glycolic and fast oxidative fibers B. May fatigue more quickly than fast glycolic and fast oxidative fibers C. Do not produce ATP D. Use primarily anaerobic glycolysis E. Use primarily aerobic respiration 2013-03-06 There are actually two different types of fast twitch muscle fibres, and though both share some commonalities, there are also clear differences between them.

Also known as intermediate fibers. They possess a moderate number of mitochondria and they obtain their energy through a combination of aerobic and anaerobic metabolism. Their resistance to fatigue and efficiency is moderate. Their speed of contraction falls between the slow fibers and the fast glycolytic fibers. Based on physiological characteristics, human muscle fibers are fast fatigable, fast fatigue resistant, fast intermediate, or slow fibers; based on biochemical properties they are fast glycolytic type IIb fibers, fast oxidative- glycolytic type IIa fibers, or slow oxidative type I fibers.

Type IIa fibers are also known as fast oxidative fibers. These fibers contain high amounts of mitochondria and myoglobin and they are also red in colour.
