To investigate the influences of physical exercises on lipid metabolism in human, serum lipids were -determined in swimming, weight lifting and wrestling athletes after loading their proper exercises for certain periods of time. Atherolipid numbers were also determined in these hardly exercising athletes.
Besides same time, experimental studies were carried out in rats to see tha effects of high-carbohydrate, high-lipid and high-protein diets of 1, 2, 4 and 8 weeks duration upon serum total cholesterol ,level after the physical exercises.
The results obtained were as follows:
1. In studies with athletes, the serum concentration of various forms lipids and atherolipid number were increased for some periods of time by imposing physical exercises.
2. In experimental studies with rats, various dietary effect upon the serum total cholosterol level .after loading physical exercises were as follow; on high-lipid diets, the serum level increased upto the 4th week and thereafter kept the same increased level until the 8th week; on high-carbohydrate diet, the level increased upto the 2nd week and extended to the 4th week with the same increased level, but somewhat decreased at the 8th week; and on the high-protein diet, the level increased upto the 2nd week, and decreased progressively from the 4th week.
