WebMay 7, 2015 · Type IIB fibers do not have mitochondria and have a colorless appearance, which is why they are known as white fibers. Because they have a limited supply of stored energy, and thus fatigue quickly, Type IIB fibers are used for strength and power activities requiring a high amount of force in a short period of time. WebNov 18, 2024 · In contrast, white fibers (fast-twitch fibers) are larger in diameter. Their mitochondria and lipid droplets are smaller and less numerous than those of red fibers [ 2 ]. The properties of red muscle fibers make them very effective in postural maintenance, while white muscle fibers are suited for bursts of intense muscle activity [ 3 ].
