In order to clarify the roles of endocrine responses to exercise, various hormones and metabolic parameters were determined at the same time. Eleven long distance runners performed treadmill running until exhaustion. Blood samples were obtained before, immediately after, and at 30 and 60 minutes following the exercise. Urine samples were collected before and after the exercise and change in body weight was also determined. Elevations in plasma ACTH, ADH, renin activity, glucagon, GH and serum cortisol were accompanied by a fall of blood pH, and rises in blood lactate concentration and ammonia, suggesting that these metabolic changes induced by strenuous exercise caused a stress reaction. Body weight and urine volume were decreased after the exercise. Increases in Ht and total protein concentration indicate hemoconcentration. The rise in plasma ADH may be induced by elevated osmolarity and reduced plasma volume in addition to stress reaction. The elevation of plasma renin activity may have resulted from reduced plasma volume and stress reaction. Increases in plasma renin activity and ACTH may induce a rise in aldosterone which may have induced a significant decrease in urinary Na/K. Elevations of plasma glucose and serum FFA were accompanied by rises in glucagon and GH. A rise in insulin may be induced by the elevated plasma glucose. A significant rise in plasma testosterone was observed after the exercise, but when the rise was corrected by hemoconcentration the elevation of testosterone was not significant any more. Thus, determinations of various parameters offer a deep insight into endocrine responses.
