ABSTRACT
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.<BR>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<SUB>1</SUB>-, α<SUB>2</SUB>-globulin, transf errin and γ-globulin were observed.<BR>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.<BR>These results mentioned above would suggest the exsistence of some relationship between the total volume of exercise and excretion of urine protein, especially albumin.
ABSTRACT
In the studies of physical motion analysis the multiple photographic method with a stroboscope or the fast motion picture which has been used, are not sufficient to pursue a motion of some kinds of sports and of some hidden physical spot only from one direction and difficult to synchronize picture obtaind from three direction.<BR>To make use of electrical engineering from the points of Physiology and Kinesiology, it is worthy of pursuing a physical motion on three dimensions, up & down, right & left and before & behind at once, and furthermore, physiological phenomena in electrocardiogram and electromyogram with connection to the above analyzer.<BR>For that purpose a physical locomotion pursuit analyzer (SN-type, refered to PLPA later on) was devised.<BR>The present devised analyzer is composed of a three dimensions-accelerometor in a gyroscope, a preamplifier, a integration amplifier and a pen-writing recorder.<BR>As already known in the principle of physics, velocity can be obtained by single integration of acceleration rate and displacement by double integration of a acceleration rate.<BR>In above the PLPA, therefore, acceleration rate, velocity and displacement, each of three dimensions can be determined. Capacity of the present analyzer was as follows; Frequency rate : 1.5-20.0 HZ (Static accelerated component under 1.5 HZ was cut by differentiation circuit of DC-cut), time constant of electrical integration circuit : about 0.2sec.<BR>In the present report the outline of PLPA and some data of our experiments obtained by use of it were dealt.<BR>The problems of the telemetering system of this analyzer and digital exhibition by connection to computer require further study.
