HORMONAL RESPONSE TO A SHORT-TERM EXERCIS E AND UNDER EFFECT OF TRAINING

Physical exercise induces a mobilization of energy substrates in order to furnish fuel for metabolic pathways. A part of this regulation is under hormonal influences. A decrease in plasma insulin and an increas e in catecholamines play a central role. It results an enhanced lypoly sis. The increase in insulin sensitivity favours muscle glucose consum ption in spite of hypoinsulinemia during exercise. These coordinated a ctions indicate that physical training is able to influence the mechan isms of type 2 diabetes with insuline resistance when the etiology of type 1 diabetes is not influenced by physical training. Physical exerc ise exerts a synergic effect with diet in the treatment of obesity but it is unefficient alone. The action of physical training on metabolic disease is related to the level and duration of training.
