Proteinuria during the 24-hour period following exercise

Abstract

The urine of 10 football players, collected for 24 hours following a practice game, was found to contain 2.3–15.2 times as much protein as urine collected following a period of rest. No changes were noted on electrophoresis of the serum proteins. The renal clearance of serum albumin increased more than the clearance of serum globulins following exercise, but in both the control and post-exercise specimens the clearance of globulins and percentage of globulins in the urine usually exceeded these values for albumin. Considerable variation in the excretion of proteins was noted among individual subjects in the control period; as protein excrextion increased following exercise, the protein excretion patterns became more uniform in these subjects. Compared to the previously described exercise proteinuria which occurs immediately following exercise, this second phase is characterized by less intense protein excretion and longer duration.

“…Es una forma común de proteinuria que se presenta asociada a la fiebre, 28 el ejercicio excesivo, 29,30 la exposición al frío, el estrés emocional, las convulsiones e inclusive al embarazo normal. 31,32 A este tipo de proteinuria se le conoce como funcional porque no existen defectos renales intrínsicos estructurales ni funcionales.…”

“…Gardner (1956) originated the term athletic pseudonephritis to characterize the patterns of urinary protein excretion induced by exercise that is to be benign, transient, and reversible. Since then, proteinuria has been shown to occur after non-traumatic exercise such as rowing (Poortmans, 1990), swimming , marathon running (Irving et al 1986) and triathlon (Farber et al 1987) and traumatic sports such as football (Coye and Rosandich, 1960) and baseball (Miyai and Ogata, 1990). It has been suggested that exercise-induced proteinuria noted by the acutely abnormal urinary findings decreases and returns to the baseline within 48 hours (Gardner.…”
