Abstract
Electrical stimulation, when accompanied by high temperature incubation, was found to lower the extractability of myofibrillar proteins and increase their degradation, particularly that of the myosin component. Troponin T and myosin light chain 2 were similarly affected. Troponin T and troponins I and C were degraded earlier during ageing in electrically stimulated muscles incubated at high temperature than in conventionally chilled muscles.
