[The effect of exertion on carbohydrate metabolism in myocardium of animals with experimental diabetes].

The aim of our experimental work was to investigate the carbohydrates metabolism in myocardium of experimental diabetic animals which were physically trained. The experiment was carried on a group of seventy white Wistar rats, which was divided into four subgroups. The first and the second subgroups consisted of normal animals. The alloxan diabetic animals belonged to the third and fourth subgroups. The animals of second and fourth subgroups were forced to physical efforts. The concentration of glycogen as well as lactic, pyruvic and citric acids in myocardium of all experimental rats were estimated. The most important results of the experiment was the observation of the changes of concentration of the lactic and citric acids in the myocardium. The other satisfactory issue was that the short-term physical training which had been forced on experimental diabetic rats for four following days were good influence for them. The intensive metabolism of lactic acid was observed of those diabetic rats.
