They are red in color due to the presence of large volumes of myoglobin (iron-oxygen binding protein) and high numbers of Mitochondria (power house of the cell). They are very resistant to fatigue and are capable of producing repeated low-level contractions by producing large amounts of ATP (Adenosine triphosphate) through an aerobic metabolic cycle.
