Plasma cortisol and plasma aldosterone levels were measured before and immediately upon completion of a marathon run in 7 highly conditioned male subjects in order to evaluate the response of the adrenal cortex to physical exertion. Both cortisol and aldosterone values rose significantly in response to the stress of the muscular exertion of the 26 mile, 385 yard run.
