It has been established that the activity of calpains and the amount of neutrophil myeloperoxidase in skeletal muscles of rats increases after the 24-48 h-rest, that followed an intensive single physical exercise. Adaptation which appears as a result of systematic physical exercises causes less pronounced changes in the activity of proteolytic enzymes. Free ubiquitin content in skeletal muscles remains unchanged during training and in posttraining periods.
