Green 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.

In the present study, 5 ㎎/㎏ BW glucocorticoid (GC) was used for loping osteoporosis. After this treatment, 5 ㎎/㎏ BW alendronate (A) was injected in the abdomen for the medical cure and exercise regimen was performed for weeks. Exercise-training was designed endurance exercise with treadmill exercise (TM), 28 m/min, 30 min/day, 5 day/week. Bone mineral density(BMD), bone mineral content(BMC), and bone intensity were measured with DEXA and Instron. Bone length and diameter were measured with caliper and blood calcium was analyzed with enzymatic method. Osteoporosis induced with GC was higher in BMC. In addition, BMD, intensity, bone length, diameter, and blood calcium was tended to reduce but not significantly different between treatments. GC-A group has increased BMD and blood calcium than other treatments (p<0.05). Diameter and intensity, however, were not significantly different. TM has increased bone length of GC-TM and GC-ATM compared to GC-A (p<0.05), however; diameter was not. These results suggested that only the exercise-training regimen after glucocorticoid-induced osteoporosis is too stressful in rats. Therefore, exercise training combined with alendronate administration is better method to increase those effects.
