  • 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.

They contain more mitochondria and myoglobin, and are aerobic in nature compared to fast-twitch ...

Fast-twitch muscle fibers are the type II muscle fibers that can generate a high power for a short period of time. On the other hand, slow-twitch muscle fibers are the type I fibers that can generate a moderate power for a long period of time. They do not become fatigued soon.

Fast-twitch muscle fibers are best suited for glycolytic energy production. What is the body's major storage form? The body stores much more energy in the form of fat than in the form of glycogen.

They’re known as oxidative-glycolytic muscles because they can use oxygen and glucose for energy. These fast twitch muscles have a higher number of mitochondria than the other type, Type IIb.

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. Fast-twitch fibers have a high threshold and will be recruited or activated only when the force demands are greater than the slow-twitch fibers can meet.

Fast Twitch (Type II) Fast-twitch fibers are good for rapid movements like jumping or sprinting that require fast muscle contractions of short duration. Unlike slow-twitch fibers, fast twitch-fibers rely on anaerobic respiration (glycolysis alone) to produce two molecules of ATP per molecule of glucose.

Fast-Twitch Fibres. The two types of fast-twitch muscle fibres differ from the slow-twitch fibres because they can produce energy in the absence of oxygen (glycolytic oxidation). This allows them to create energy quicker using phosphocreatine and glycogen to fuel those quick explosive movements such as jumping and sprinting.
