Abstract

G
reen tea is widely consumed beverage in the world especially in Asia. It is known to have antioxidative activity and blood lipid lowering effect. In this point of view, green tea extracted polyphenol (50 ㎎/㎏) was administered for 5 wks with treadmill exercise training in experimental rats (EXP; n=8) or water as a placebo (CON; n=8). Blood lipids, total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) were analyzed and calculated with enzymatic methods. Superoxide dismutase (SOD) and malonedialdehyde (MDA) in liver were analyzed as reported elsewhere. TC and LDL-C, cause of arteriosclerosis, were significantly reduced in FXP (p<0.05). SOD was significantly increased in EXP and MDA was significantly decreased in EXP (p<0.05). These results suggested that green tea polyphenoll decreased the blood lipids and lipid peroxidation by exercise training.
