football participation requires considerable utilization of both aerobic and anaerobic energy systems to match the high energetic demands of the sport. the consequent stresses imposed on the physiological and metabolic systems carries players to the threshold of exhaustion during match-play, from which they are required to recover in preparation for the subsequent game. a high number of players...

in this study, the energy reserves of prediapause and diapausing adult bugs were examined using colorimetric biochemical techniques to determine carbohydrates, lipids, glycogen, and protein content. to this end, 45-day-old bugs were obtained from three different sources: laboratory colony, cold-stored insects, or natural habitat. the results showed that prediapause males and females had signifi...

the aim of this article is to review health-related aspects of ramadan fasting in normal individuals and diabetics. during fasting days of ramadan, glucose homeostasis is maintained by meal taken bepore dawn and by liver glycogen stores. changes in serum lipids are variable and defend on the quality and quantity of food consumption and changes in weight. compliant, well controlled type 2 diabet...

To test the hypothesis that cortisol and epinephrine have direct regulatory roles in muscle glycogen metabolism and to determine what those roles might be, we developed an in vitro white muscle slice preparation from rainbow trout (Oncorhynchus mykiss Walbaum). In the absence of hormones, glycogen-depleted muscle slices obtained from exercised trout were capable of significant glycogen synthesi...

Healthy neurons do not store glycogen while they do possess the machinery for the glycogen synthesis albeit at an inactive state. Neurons in the degenerating brain, however, are known to accumulate glycogen, although its significance was not well understood. Emerging reports present contrasting views on neuronal glycogen synthesis; a few reports demonstrate a neurotoxic effect of glycogen while...
