金乙祥,琴惠卿 단국대학교 1993 論文集 Vol.27 No.-
The purpose of this study was to investigate the relation of exercise and plasma lipoproteins which have the important functions for metabolism and transport of plasma lipids. The subjects of study were twenty male athletes in Korean National College of Physical Education. Their nutrient intakes were surveyed by weighing method, and plasma lipoproteins were determined by eletrophoretic method during the body weight reduction and exercise. And A group was loaded 70-80%, and B group loaded over 85% in maxiam oxygen consumption. The results obtained were as follows ; 1. According to the dietary analysis, in A group, the average intake of energy was 1915.5kcal per day of one man. in B group, was 1922.2kcal. Rates of energy composition were 60.7% in carbohydrate, 16.7% in protein and 22.6% in fats in A group and 61.5% 15.9%, 22.6% respectively, in B group. 2. Before and after body weight reduction, β-lipoproteins(LDL+VLDL) content in plasma of A group and B group were more decreased. And α-lipoprotins(HDL) content in plasma of A group and B group were more increased. 3. In "3rd step", β-lipoproteins content in plasma of A group were more increased in comparison to B group. In "4th step", β-lipoprotein content in plasma of B group were more increased in comparison to A group. 4. After exercise, progressive changes of plasma lipoproteins in each groups, α-lipoprotein content in plasma of A group and B group were more decreased gradually.
