유영운동이 콜레스테롤 식이 흰쥐에 있어서 간 조직의 항산화물질 및 혈액 성분에 미치는 영향
백영호,김세중,정해영,최진호,Beak, Yeong-Ho,Kim, Se-Jong,Chung, Hae-Young,Choi, Jin-Ho 한국생명과학회 1997 생명과학회지 Vol.7 No.4
The purpose of this study was to investigate effects of swimming training and cholesterol diet on the activation of hepatic antioxidant enzymes and serum lipid in Sprague Dawley rats(24 weeks of age). They were divided into five groups which were made up of normal-diet detraining group(C), 2% cholesterol-diet detraining group(CC), 2% cholesterol-diet swimming training groups which were classified according to their training time(CSA: 12min, CSB:8min, CSC:4min). They were given normal diet for the first 6weeks and then, separated normal-dietary and 2% cholesterol-dietary for 14 weeks. During these periods, 10 weeks’ swimming training was performed after 4 weeks later. And then we analyzed blood and liver by decapitating those rats. Swimming training showed a tendency to increase the activation of GSH-peroxidase, Nonprotein-SH and malondialdehyde, and decrease total- cholesterol, LSL-C/HDL-C and VLDL significantly. Whereas, cholesterol diet which has no training showed decrease the activation of hepatic antioxodant enzymes, and increase total-cholesterol and LDL-C/HDL-C absolutely. These results suggest that swimming training should stimulate the activation of hepatic antioxidant enzymes and decrease total-cholestrol even if they had cholesterol diet.

Occurrence of Atherosclerosis can largely be attributed to blood serum cholesterol. panicular attention should be paid to the increase of LDL cholesterol and decrese of HDL cholestrol as risk factors. HDL cholesterol is a lipo-protein that prevents atherosclerosis. Total-cholesterol and LDL-cholesterol level was decreased significantly by exercise, training, HDL-cholesterol level was increased significantly by exercise training. Saturated fatty acid was not significant change serum at retraining, monoens was little decreased, polyenes was little increased, ratio of saturated fatty acid, also, was increased, but these results were not able to say sure by different level of fat diets. By retraining, ratio of n-3/n-6 was significant decreased, but ratio of unsaturated fatty acid for saturated fatty acid was significantly increased, change was not admitted by different level of fat diets. Therefore, researcher decided that exercise effect more than different level of fat diets on change of fatty acid in blood. Ditary fibers promote exercise of the digestive tract and shortens the time food remains inside the digestive tract. It can prevent obesity, hyperlipidemia, aterosclerosis and colin cancer by blocking the absorption of cholesterol. Various vegetables and sea foods are richin unsaturated fars and can act prevent the absorption of cholesterol inside the digestive tract. Risk factors of aterosclerosis is Hypertension, hyperlipidemia, diabetes, obesity, physical inactivity and excessive smoking. Aterosclerosis begins at young age worsens with age, paeticularty more so un men than women. For people with risk factors of atheroscleroisi, it is important to prvent atherosclerosis-related disease with dierary, living pattern and exercise prescription. For ideal exercise, it should be aerobic with Intensity of 70∼85%HRmax(50∼70%, Vo2max), duratin of 20∼60min/day. The frequency of 3∼5/week is desirable the better exercise presscription is endureance aerobic execose. To get more effect exercise, exercise consisitency very important. Regular exercise is effective in preventing coronary disease such as angina pectoris and infaction, inside it can lower the blood pressure and aids in weight control and release of stress.
