The oxygen-binding. function of myoglobin, in situ in the bundles of muscle. fibers, was abolished by chemical treatment, and the contribu-. tion of myoglobin toward the oxygen uptake of the muscle fiber. bundles was estimated from the difference in the steady state.

Type IIB fibers, also called fast twitch or fast glycolytic (anaerobic) fibers, contain a low amount of myoglobin, mitochondria, and capillaries so they are white in color. Type IIB fibers create ATP at a slow rate through anaerobic metabolism but split it at a very fast rate.
