THE POST-EXERCISE SUPPRESSION OF KIDNEY FUNCTION IN MAN

Abstract
Diuresis was produced in 33 young adult athletic women by 600 cc. of water in a single dose of 1000 cc. in divided doses, 100 cc./15 min. Brief violent exercise suppressed kidney function for 45-60 min. The greatest excretory diminution occurred 45 min. after exercise, even when the activity was introduced after absorption was complete. The hypothesis suggested ia that oliguria occurs because of a disturbance in the balance of osmotic and hydro-static pressures which reduces the glomerular filtrate until the cardiovascular and physicochemical disturbances of violent exercise subside.
