Class, note how the sympathetic-like effect of epinephrine and norepinephrine is to increase all metabolic and physiological variables, preparing the body for the demands of exercise.
Aldosterone is very involved in electroylte balance of Na+ and K+ during exercise. Cortisol may inhibit protein synthesis if the body is low on carbohydrates. See graphic below. It shows how cortisol helps to transport amino acids in muscle (that were to be used for protein synthesis). These amino acids (from muscle) will be utilized in the liver to make new glucose, referred to as gluconeogenesis.
