The post-exercise glycogen recovery in tissues of trained rats.
The post-exercise glycogen recovery in myocardium, liver, diaphragm muscle and musculus biceps femoris was compared in untrained and trained rats. The glycogen level in myocardium of the trained rats was significantly higher than that in the untrained ones only immediately after the exercise-test and on the second day after the exercise. The liver glycogen levels on each of the examined post-exercise days were similar in both groups and did not differ from the control values. The post-exercise glycogen recovery in the diapraghm muscle of the untrained rats was also similar to that in the trained animals. In musculus bicpes femoris similar post-exercise supercompensation was found in both groups except on the second day when the glycogen level in the trained animals was significantly higher than that in the untrained ones. The results suggest that it is necessary to separate the effects of training from those of the last bout of exercise in the training program when the effect of training is examined.
