*Muscles remain biochemically active after the death of an animal

−

*Following a period of relaxation, contraction and stiffening occurs

−

*Due to deficiency of ATP releasing myosin heads from their binding sites at end of power stroke

−

*Onset faster in ATP deprived animals (starvation, hunting, tetanus...)

*May be absent in cachetic animals

−

*Disappears due to autolysis or putrefaction
