흰쥐의 연령증가에 따른 일시적 최대운동 부하시 혈장 콜레스테롤, HDL, LDL 및 TG 농도의 변화 = Changes of Total Cholesterol,HDL,LDL and Triglyceride Concenbtration during Acute Maximal Swimming Exercise in Different Aged of Rats

다국어 초록 (Multilingual Abstract)

The purpose of this study estimated whether a life style and diet pattern or natural phenomenon induced to aging in changes of plasma lipid component. Also, It was estimated from the changes of plasma lipid component followed acute maximal swimming exercise in different aged rats.
Three months, nine months and sixteen months male rats of a Sprague-Dawley were housed in individual cages, and they were separated into each two group.
- 3 month (12) : Control (6) and Experimental (6)
- 9 month (22) : Control (10) and Experimental (12)
- 16 month(16) : Control (8) and Experimental (8)
In the 3.9.16 month, half of control group was randomly sacrificed. The other half of experimental group was performed with swimming exercise until exhaustive state. Water tank of 50cm depth and 50cm diameter was used for this study. Rats were given a 5 min warm up with swimming exercise, this warm up was followed by taking 5 min rest period, then animal exercised until exhaustion.
Plasma cholesterol, HDL, LDL and TG levels followed aning of 3,9 and 16 months was not shown a significant difference between control group.
Also, Plasma cholesterol, HDL and LDL levels of experimental group was not displayed statistically significant difference between 3,9 and 16 month group, but there was a significant difference(p<.05) between control and experimental group of 16 month, and between experimental group of 3 month and 16 month(p<.05) in levels of triglycerides.
Conclusively, This study suggested that changes of plasma lipid component induced by aging was not phenomenan due to increase of age, and conditions except for life style and diet patern, etc. was similar to a changes of lipid component induced as exercise.
