title: [Adaptation of the heart of the experimental animal to physical loading (morphometric characteristics)].
abstract: Physical loadings produce in experimental animals various adaptive rearrangements in the cardiac muscle parts. Peculiar changes in the parts of the hyperfunctioning myocardium essentially depends on the character of physical strains. Static physical loadings produce an increase of the cardiac mass with a predominant hypertrophy of the right ventricle and dilatation of its cavity in most rats. Under swimming--in half of the observations the cardiac hypetrophy occurs mainly at the expense of analogous structural rearrangement in the left ventricle.
