[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.

[Glycogen and glucose content in the tissues of the frog and reptiles].

In poikilotherm animals--the frog Rana ridibunda, lizards Lacerta strigata, Eremias arguta, snake Natrix tesselata--high glycogen and glucose concentrations have been found not only in the liver, but also in muscles and especially in the brain. The content of glycogen in the brain of the reptiles investigated is 63.5--4.2 times higher, whereas that of glucose--6.9--39.5 times higher than in the brain of rats. The level of free fatty acids in the blood of frogs and snakes studied is the same as in rats, being 3.8 times higher in the blood of the lizards.
