[Effect of immersion on the urinary excretion of aldosterone in trained and untrained male subjects (author's transl)].
Diuresis, the excretion of aldosterone-18-glucuronide and the excretion of sodium and potassium were measured before and during two periods of immersion in four male athletes in training and four untrained male subjects (age 20-27 years). The increase in diuresis during immersion was accompained by a concomitant decrease of aldosterone excretion and increase of sodium excretion in urine. These changes were more pronounced in untrained subjects than in trained subjects. From these results it may be concluded that trained subjects react more sensitive to slight changes in aldosterone secretion than untrained subjects.
