WebMay 17, 2024 · Concept Review. The three types of muscle fiber are slow oxidative (SO), fast oxidative (FO) and fast glycolytic (FG). SO fibers use aerobic metabolism to produce low power contractions over long periods and are slow to fatigue. FO fibers use aerobic metabolism to produce ATP but produce higher tension contractions than SO fibers. WebIn contrast to red muscle fibers, white muscle fibers have less myoglobin and mitochondria and have poor blood flow. Conversely, they have higher glycogen content and glycolysis enzymes. They are also very efficient for a strong and fast contraction of short-term anaerobic metabolism-fuelled contraction.
