5.3.3 Types of muscle fibres and muscles
Factors affecting muscle fibre type
Post mortem characteristics of fibres
White fibres have a more highly developed which influences the response of muscle to changes in temperature and pH early post mortem. White muscles, because of their predominantly glycolytic nature, exhibit much more rapid lactic acid accumulation early post mortem. For this reason they are more susceptible to problems associated with rapid post mortem glycolysis. Alternatively, muscles with higher proportions of white fibres are more resistant to pre-rigor shortening than those composed of red.
