Fast fibers are not associated with red muscle fibers, but rather with white muscle fibers. Red muscle fibers are also known as slow-twitch fibers and are associated with endurance activities. They contain high levels of myoglobin and large amounts of oxygen, as well as many blood vessels. They are also responsible for postural muscles due to their capacity for sustained, prolonged contractions.
