What is the difference between white and dark meat in a chicken?

Pale fibres: Fast twitch muscle fibres having low amounts of mitochondria and myoglobin, signifying reduced reliance on oxidative phosphorylation. Uses glycolysis to generate large amounts of force in a short period of time, however this is unsustainable and can only be achieved for a short burst. Fatigues easily. Red fibres: Slow twitch muscle fibres having high amounts of mitochondria and myoglobin, signifying reliance on oxidative phosphorylation. Force buildup takes time and maximum force is lesser than that of fast twitch fibres, however this can be sustained as long as adequate oxygen is delivered.
