Fast-glycolytic muscle fibers are another name for Type IIb skeletal muscle fibers and are white in color. The skeletal muscle fibers are divided into three types: Slow-contracting muscle fiber (Type I), Fast-contracting muscle fiber (Type IIa) and Fast-contracting muscle fiber (Type IIb).
Fast-glycolytic muscle fibers Type IIb are abundant in muscles of the lower limbs that contract quickly and are oxygen dependent, prevalant in postural muscle of the back, generate lots of power and depend on lots of power and depend on anaerobic pathways to make ATP , have fewer but larger myofilaments and numerous mitochondria, have abundant myoglobin.
