type iib muscle cell
"A type II muscle cell that contains a low content of myoglobin, relatively few mitochondria, relatively few blood capillaries and large amounts of glycogen. Type II B fibres are white, geared to generate ATP by anaerobic metabolic processes, not able to supply skeletal muscle fibres continuously with sufficient ATP, fatigue easily, split ATP at a fast rate and have a fast contraction velocity."
