Since manifestation of exercise proteinuria was reported by Leube (1878) , the nature of exercise urinary protein has been extensively studied. The physiological mechanisms of increased excretion of urinary protein during and after exercise still remain to be obscured. The investigation presented here, were performed for the purpose of knowing the decreasing rate of soccer players body weight in each position during the soccer game, which was considered as a prolonged heavy exercise, of identifing the excretion of exercise proteinuria after performance of the game, and of studying the relation among urinary total protein at that time and its fraction in disc-electrophoresis. The protein fractions of urine by disc-electrophoresis, compared with serum, manifested slight albumin fraction at rest, but it much increased after the game, and furthermore α_1-, α_2-globulin, transferrin and γ-globulin were observed. The decreasing rate of body weight , total protein level and its albumin fraction mutually have the parallel relationship. Urine albumin fraction could have a relation to the decrease of body weight of athlete in each position rather than total protein. These results mentioned above would suggest the exsistence of some relationship between the total volume of exercise and excretion of urine protein, especially albumin.
