Effect of AICAR treatment on glycogen metabolism in skeletal muscle.
AMP-activated protein kinase (AMPK) is proposed to stimulate fat and carbohydrate catabolism to maintain cellular energy status. Recent studies demonstrate that pharmacologic activation of AMPK and mutations in the enzyme are associated with elevated muscle glycogen content in vivo. Our purpose was to determine the mechanism for increased muscle glycogen associated with AMPK activity in vivo. A...
متن کاملThe Effect of Exercise and Diet on Muscle and Liver Glycogen Repletion in Standardbred Horses
Muscle and liver glycogen are important substrates for energy generation in horses performing various intensities of exercise. In a review of energy considerstions during exercise, Hodgson (1985) summarized a number of experiments that measured muscle glycogen utilization in horses performing a wide variety of exercises from endurance rides covering up to 160 km to Thorougbreds racing at speeds...
متن کاملRabbit Skeletal Muscle Glycogen
Glycogen in its particulate beta-form is localized in the sarcoplasm close to the sarcoplasmic reticulum. Some particles are in close contact with the membranes, on the outer side of the vesicles. The mild technique of differential precipitation-centrifugation has been adapted to the preparation of glycogen from adult skeletal muscle. A preliminary low-speed centrifugation which eliminates the ...

متن کاملPost-exercise muscle glycogen repletion in the extreme: effect of food absence and active recovery.
Glycogen plays a major role in supporting the energy demands of skeletal muscles during high intensity exercise. Despite its importance, the amount of glycogen stored in skeletal muscles is so small that a large fraction of it can be depleted in response to a single bout of high intensity exercise. For this reason, it is generally recommended to ingest food after exercise to replenish rapidly m...
