In general, muscles with a
higher percentage of type IIB fibers are more susceptible to postmortem
glycolysis due to their high glycolytic capacity than muscles with
a higher percentage of type I fibers. The percentage of type IIB fibers is
also positively correlated with the production of lactate and negatively
correlated with glycogen content in the early postmortem period,
whereas higher percentages of type I fibers are associated with higher
muscle pH and WHC
