title: Effect of exercise on the lipid content, lipid fatty acid composition and morphology of myocardial and skeletal muscles in rat.
abstract: The effect of exercise on the morphology of the myocardial and skeletal muscle, total lipid content and lipid fatty acid composition was checked in rats fed a rapeseed oil-containing diet. The graded exercise was found to reduce the growth rate of animals. Myocardial fatty degeneration was less intense and erucic acid content lower in trained rats fed a diet with 50% kcal of rapessed oil than the untrained ones. The opposite was true when rapeseed oil supplied 30% of calories. Histiocytic granulomata were more numerous in trained rats. Exercise failed to affect the accumulation of erucic acid in skeletal muscle.
