REGULATION OF ENERGY-METABOLISM DURING EXERCISE

This review deals with the peripheral sympathetic mechanisms involved in the regulation of energy substrate homeostasis during exercise. We have developed an experimental model for assessing sympathetic influen ces on metabolic processes in the awake and exercising rat. The data i n this survey particularly focus on the exercise-induced alterations o f the plasma concentrations of the catecholamines, adrenaline (A) and noradrenaline (NA), on the differences between adrenal A and neuronal NA, and on the role of pre-and postsynaptic adrenoceptors in the regul ation of energy metabolism during exercise.
