[Classification of physical exercise]

Physical exercises are a major mean of therapeutical physical conditioning. Since muscle activity forms the basis for physical exercises, their classification should be based on the criteria and signs which characterize muscle performance (the type of muscle contraction, oxygen uptake, intensity, etc.) and affect the human body. It is necessary to make a classification of physical exercises on the basis of the major signs characterizing muscle activity in order to improve a learning process and physicians' professional activity.
