WebbType I muscle fibers, or slow-twitch muscle fibers, are red in color and contain high concentrations of mitochondria. Type II muscle fibers, or fast-twitch muscle fibers, are white in color and have low concentrations of mitochondria. WebbThe slow twitch fibers generate energy for ATP re-synthesis by means of a long term system of aerobic energy transfer. These mainly include the ATPase type I and MHC type I fibers. They tend to have a low activity level of ATPase, a slower speed of contraction with a less well developed glycolytic capacity.
