anaerobic muscle fibers: Human muscle fibers are an interwoven mixture of aerobic and anaerobic fibers, whereas other animals, such as chickens, have entire muscle systems that are either aerobic or anaerobic. The dark meat in a cooked chicken is dark because these muscles were used to provide aerobic energy and are filled with oxygenated blood; white meat is anaerobic, and so is lacking in these red pigments.
