Sparing of muscle glycogen
Web23. sep 2012 · However, the mechanism underlying this ergogenic effect is less clear. Euglycaemia and oxidation of blood glucose at high rates late in exercise and a decreased rate of muscle glycogen utilisation (i.e. glycogen ‘sparing’) have been proposed as possible mechanisms underlying the ergogenic effect of CHO ingestion. Web15. sep 2013 · The use of electron microscopy has revealed that glycogen is not homogeneously distributed in skeletal muscle fibres, but rather localized in distinct pools. Furthermore, each glycogen granule has its own metabolic machinery with glycolytic enzymes and regulating proteins.
