초록

생후 4주령 Sprague Dawley계 수컷 흰쥐를 분양 받아 청국장식이유산소운동군 8마리, 청국장식이군 8마리, 유산소운동군 8마리, 대조군 8마리, 총 32마리를 대상으로 구분하였다. 운동은 6주간, 주 5회, 경사도 0%, 속도 15~16 m/min으로 하고, 1주차 25분, 2~3주차 30분, 4~5주차 35분, 6주차 40분이 되도록 실시하였고, 청국장은 20% 청국장 첨가식이를 1일 20 g 기준으로 섭취시킨 결과는 다음과 같다. 청국장 식이와 유산소 운동은 혈중지질중 T-C, TG, HDL-C에서 긍정적인 효과가 나타났고, 항산화효소 중 SOD에서 긍정적인 효과가 나타났다. 이는 유산소 운동의 혈중지질의 개선, 항산화 효과와 청국장에 함유된 레시틴(lecithin), 사포닌(saponin), 글라이시틴(glycitin), 파이틱산(phytic acid) 등의 성분들의 시너지 작용으로 긍정적인 영향을 미친 것으로 사료된다. 그러나 LDL-C, TBARS, CAT, GPx의 차이는 나타나지 않았다. 차후 연구에서 운동강도, 빈도, 지속시간과 청국장의 섭취량 등에 변화를 준 다각적 연구가 필요할 것으로 사료된다.

The purpose of this study was to examine the effects of a cheonggukjang diet and aerobic exercise on lipid metabolism and antioxidant enzyme activity in rats. Thirty-two Sprague Dawley rats were randomized into a cheonggukjang diet with aerobic exercise (A), aerobic exercise (B), cheonggukjang diet (C), and control group (D). The cheonggukjang diet group consumed 20 g of 20% cheonggukjang a day with their normal diet. Exercise training consisted of treadmill running (25~40 min, 5 day/wk) and the exercise intensity was gradually increased. The results are as follows: T-C was significantly lower (p<0.05) in A compared to B and C. TG was significantly lower (p<0.001) in A compared to D. B and C were significantly lower than D. HDL-C was significantly higher (p<0.05) in C compared to D. LDL-C was not statistically different across the groups. Additionally, TBARS were not statistically different in the control or experimental groups. SOD was significantly lower (p<0.05) in A compared to D. C was significantly lower (p<0.05) that of D. CAT and GPx failed to reach the statistical difference between experimental and control groups. The major findings of this study were that aerobic exercise with a chenggukjang diet intervention improved lipid profiles and antioxidant capacity in this animal model. Therefore, a cheonggukjang diet and aerobic exercise will help to improve antioxidant capacity and prevent lifestyle related diseases.
