4주간의 트레드밀 운동과 단백질 식이가 흰쥐의 면역글로불린 및 항산화효소에 미치는 영향

Abstract

The purpose of this study was to investigate the effects of treadmill exercise and a protein diet on immunoglobulin and antioxidant enzymes in rats. Forty-four male Sprague-Dawley rats, 5 weeks old, were used. Experimental groups were divided into exercise with protein diet group (A, n=11), exercise group (B, n=11), protein diet group (C, n=11), and the control group (D, n=11). Exercise was administered through a treadmill running program (14 ～18 m/min, 0˚ grade, 20 min/day, 5 day/wk) and these rats were given a 40% protein diet for 4 wk. The results of this study are as follows: the protein diet group showed a significant increase in IgG of immu noglobulin compared to the exercise group and control group; the exercise with protein diet group a nd protein diet group showed a significant increase in SOD activity of antioxidant enzymes compared to the control group; the exercise with protein diet group, exercise group and protein diet group showed a significant increase in GPx activity of antioxidant enzymes compared to the control group; the exercise with protein diet group showed a significant increase in CAT activity of antioxidant enzymes compared to the protein diet group and control group. In conclusion, treadmill exercise and a protein diet were found to help with immunoglobulin and antioxidant enzymes. Further research regarding the effects of exercise and protein diets is required.
