THE RELATIONSHIP BETWEEN EXERCISE ABILITY AND NUTRITION / 体力科学

For adult rats fed on the following six kinds of diets for about 80 days, intermediate metabolic substrates in serum, liver and skeletal muscle were determined. The components of feeding diet are as follows:<BR>1. STANDARD DIEF : 18% protein, 100 oil & 65% dextrin.<BR>2. HIGH PROTEIN-HIGH FAT DIET: 29% protein, 25% oil & 39% dextrin.<BR>3. LOW PROTEIN-LOW FAT DIET: 9% protein, 2% oil & 82% dextrin.<BR>4. STANDARD DIET modified with choline chloride & vitamin B, C & E.<BR>5. HIGH PROTEIN-HIGH FAT DIET modified with choline chloride & vitamin B, C & E.<BR>6. LOW PROTEIN-LOW FAT DIET modified with choline chloride & vitamin B, C & E. (reference : 1, 2, 3 ; due to National Institute of Nutrition)<BR>As the results increase of body weight was the least 3rd diet group, and by addition of choline chloride (above 4th, 5th & 6th diet groups) it were generally inhibited. Especially the latter phenomenon was remarkably observed in 6th diet group. Although intermediate metabolic substrates in skeletal muscle were no difference from their control levels, triglyceride and cholesterol of liver reduced also in 4th, 5th & 6th diet group, and FFA level of it increased on contrary. The triglycerides of interscapular brown fat and white fat of epididymis reduced in 4th, 5th & 6th diet groups. Furthermore, increase of triglyceride, FFA and cholesterol in serum observed in above 4th, 5th & 6th diet group, which will suggest that they might be removed from brown or white fat and choline chloride might play an important role of lipid-releasing effect from those tissues.

URINARY PROTEIN AND ITS ELECTROPHORETIC PATTERN IN SOCCER PLAYERS / 体力科学

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.
