Glycogen resynthesis in the rat muscle and liver after physical exercise.

Glycogen resynthesis was studied in muscles and liver of Wistar rats after a single bout of physical exercise, which included 30 min of enforced swimming in water at 32 degrees C. The experiment was carried out on untrained rats which rested after the exercise from 30 min to 24 h, receiving food ad libitum. During the postexercise restitution a rise was observed in the glycogen content of both tissues.

Effect of exercise on glycogen level in muscles and liver in rats.

The effect of exercise of glycogen level in skeletal muscles and liver was studied in Wistar rats. The previously untrained animals were subjected to one-time exercise in form of swimming in water at 32 degrees C for 10, 20 and 30 min. The glycogen level in the muscles (in g per 100 g of tissue) fell down during the first 10 minutes of the exercise by a mean value of 0.
