The survival of humans was strictly related to their physical capacity. To achieve Physical goals required a prompt and efficient energy system capable of sustaining either high intensity or maintaining prolonged physical activity. The oxidative phosphorylation of carbohydrates, fats to a minor extent, proteins,can sustain physical activity for many hours. Carbohydrates are the most efficient fuel for working muscle and their contribution to total fuel oxidation is positively related to the intensity of exercise. The first metabolic pathways of carbohydrate metabolism to be involved are skeletal muscle glycogenolysis and glycolysis. Later circulating glucose, formed through activated gluconeogenesis, becomes an important energetic source. Among glucose metabolites, lactate plays a primary role as either direct or indirect(gluconeogenesis) energy source for contracting skeletal muscle.
