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. WebApr 11, 2024 · One of the main difference between Red and White Muscle Fibers is the colour which is deep Red for Red Muscles because of myoglobin which is present in the sarcoplasm (cytoplasm) of the Muscle Fiber.
