Abstract: The purpose of this study was to determine the effects of different intensities of submaximal aerobic exercise on proteinuria in young football players. Ten volunteers of young football players (Age: 18±0.5 years, weight: 64.42±3.64 kg, height: 174±4 cm) were selected and participated in three sessions of aerobic activities including 30 min of running at three different intensities, 55, 70 and 85% of maximal heart rate. Before and 20 min after all three sessions, the amounts of urinary albumin, total protein, creatinine, β2-microglobuline and protein to creatinine ratio were measured and investigated using analysis of variance with repeated measurements and paired-samples student t-test. With increasing exercise intensity, the protein content of urine increased. β2-microglobuline significantly increased only for 85% of maximal heart rate. It seems that tubular proteinuria does not occur at lower intensities of activity. At lower intensities albuminuria and glomerular proteinuria take place and no proteinuria was observed for <70% of maximal heart rate intensities. Urine protein to creatinine ratio in before and after each exercise was <0.1, respectively. Thus, proteinuria after aerobic sub maximal activity with three different intensities has the physiological range.
