Lipolytic actions of hormones on adipocytes in exercise-trained organisms.
Adipocytes from sportsmen exhibited lower basal rate of lipolysis but higher response to adrenaline than those from untrained persons. Dexamethasone exposure for 30 min enhanced the adrenaline effect both in sportsmen and trained rats. Insulin abolished this glucocorticoid action. A rapid permissive action of glucocorticoids was suggested in the trained organism.
