Muscle contains a red coloured oxygen storing pigment called myoglobin. Myoglobin content is high in some of the muscles which give a reddish appearance. Such muscles are called red fibres. These muscles also contain plenty of mitochondria which can utilise a large amount of oxygen stored in them for ATP production. These muscles, therefore, can also be called aerobic muscles.
