Abstract

The purpose of this study is to identify the effects of exercise training and oak tree wood vinegar ingestion on the blood lipids and antioxidant activities of rats. The subjects were 28 Sprague Dawley male rats, and they were assigned into four groups (n=7, respectively): the control group (CON), the exercise group (EXE), the vinegar ingestion group (VIN), and the vinegar ingestion and exercise training group (VINEXE). The diet was based on high fat and oral administration of oak tree wood vinegar. The rats that were not given oak tree wood vinegar were given the same amount of distilled water orally in order to maintain the same level of stress. They were exercise trained on motor-driven treadmills during a four-week session. Weight changes in the VINEXE were significantly inhibited in the later period of exercise, when compared to the CON (p<0.05). Fat increase was significantly suppressed in VIN and EXE (p<0.05), and a synergistic effect was discovered in the VINEXE (p<0.05). Glucose and ammonia levels were significantly reduced in the EXE, VIN, and VINEXE compared to the CON (p<0.05). In blood lipids, TC and LDL-C were significantly enhanced in the EXE, VIN, and VINEXE compared to the CON (p<0.05), while HDL-C was significantly improved in the EXE and VINEXE (p<0.05). Liver MDA contents showed significant changes in each group (p<0.05), and SOD activities were significantly enhanced in the VIN and the VINEXE when compared to other groups (p<0.05). Therefore, oak tree wood vinegar ingestion with exercise training for four weeks may result in inhibition of weight gain, improvement of blood lipids, and inhibition of lipid peroxidation, contributing to health promotion.

본 연구는 운동훈련과 목초액의 장기섭취가 혈중 지질성분 및 항산화활성에 미치는 영향을 살펴보고자 하였다. 28마리의 Sprague Dawley 수컷 쥐를 이용하여 대조군(CON), 운동군(EXE), 목초액섭취군(VIN), 그리고 목초액과 운동군을 병행한 군(VINEXE)으로 각각 7마리 씩 구분하였다. 식이는 고지방식이(40%)를 기본으로 하였으며, 운동군은 4주간의 트레드밀 달리기하였으며, 목초액은 경구투여하였다. 목초액을 섭취하지 않는 집단에게는 동일한 양의 증류수를 경구투여하여 동일한 스트레스를 유지할 수 있도록 하였다. 체중의 변화는 운동 후반기에 CON에 비하여 VINEXE이 유의하게 억제되는 것으로 나타났다(p<0.05). 지방량의 변화는 VIN 및 EXE군에서 유의한 상승의 억제가 나타났으며(p<0.05), VINEXE 역시 동일한 결과가 나타났다(p<0.05). 혈액성분 중 글루코스와 암모니아는 CON에 비하여 다른 집단에서 유의하게 낮은 것으로 나타났으며(p<0.05). 혈중 지질 중 TC, LDL-C는 CON에 비하여 다른 집단이 유의하게 낮은 것으로 나타났으며, VINEXE의 유의한 상승효과가 나타났다(p<0.05). HDL-C는 EXE와 VINEXE군에서 유의하게 개선되는 것으로 나타났다(p<0.05). MDA 함량은 각각의 집단간 모두 유의한 변화를 보였으며(p<0.05), SOD 활성은 VIN과 VINEXE가 다른 집단에 비하여 유의하게 높은 것으로 나타났다(p<0.05). 이상과 같은 결과를 볼 때 4주간의 운동을 하는 동안 목초액 섭취는 체중 증가 억제 및 혈중 지질성분의 개선, 그리고 지질과산화 억제로 나타나며, 건강 증진에 도움을 줄 수 있을 것이라는 점을 시사하고 있다.
