Abstract des Autors
Glucose, lactate, free fatty acids (FFA), glycerol, epinephrine (E) and norepinephrine (NE) were measured in prepubertal boys at rest and at the 15-30 and 60th min of a bicycle exercise at 60% VO2max. Exercise induced at its onset a small decrease of blood glucose, which was significantly correlated to a large increase of NE. FFA and glycerol rose throughout the test in relation with the increase of E. Compared to the adults, the FFA turn-over was greater in boys. All these data suggest that two mechanisms, at least, come into play to prevent hypoglycemia in children during a prolonged exercise: a large increase of NE and a greater utilization of FFA.
