Abstract : An extensive review has been completed of the hormonal regulation of fluid and electrolyte balance during sedentary exposure to or exercise in the heat. The review focuses mainly on human responses although examples from animal studies are also included. The effects of exogenously administered hormones has been discussed followed by sections on hormonal response to sedentary heat exposure and exercise in the heat. Consideration of the exacerbative effects of hypohydration on the hormonal responses is followed by a section on electrolyte supplementation and the effects of heat acclimation. The review concludes with a discussion of the role of plasma volume in modifying the endocrinological responses as well as suggestions for future studies in this area. Keywords: Hypohydration, Acclimation, Electrolytes, Plasma Volume, Aldosterone, Vasopressin, Plasma Renin Activity
