Abstract
The purpose of this study is to discuss and analyze the antidiabetic effect of aquatic exercise and Cordyceps militaris combined treatment protocol on streptozotocin-induced diabetic rats over a period of 6 weeks. We used 24 male rats of Sprague-Dawley family which were divided into four groups; test group Ⅰ(aquatic exercise and feeding of cordyceps militaris; n=6), test group Ⅱ (feeding of Cordyceps miliaris; n=6), test group Ⅲ (aquatic exercise; n=6), control group Ⅳ (non-treatment; n=6). After experimenting with these four groups for 6 weeks, we measured the blood glucose, inhibitory loss of body weight, amount of feeding and GLUT-4 protein quantity. Change of glucose levels slightly decreased in group Ⅱ and significantly decreased in group Ⅲ than group Ⅳ. Change of glucose levels slightly decreased in group Ⅱ and significantly decreased in group Ⅲ than group Ⅳ. But there was more effective decrease in group Ⅰ (p<0.001). The inhibitory loss of body weight was not significantly different in groups. The amount of feeding was not different in groups. GLUT-4 protein quantity decreased in group Ⅳ compared to normal group. It was significantly increased in group Ⅰ, Ⅲ compared to group Ⅳ. But there was more increase in group Ⅰ(p<0.001). These results so far say that when we apply aquatic exercise and feeding of Cordyceps militaris diabetic rats over a period 6 weeks, it is increase GLUT-4 and the increase of insulin sensitivity of peripheral tissue. So it is considered to be helpful in improvement of glucose homeostasis.
Key Words: Aquatic exercise, Cordyceps Militaris, blood glucose, GLUT-4
