노인들의 고강도 유산소운동시 많은 산소요구량에 의하여 산화적인 스트레스가 증가하고, 결과적으로 함께 발생되는 활성산소는 MDA수준을 증가시킨다. 이렇게 노인들의 강도 높은 운동 중에 발생되는 활성산소에 홍삼복용이 어떠한 영향을 미치는 지를 알아보기 위하여 젊은이들과 비교하여 연구하였다. 노인들은 젊은이들과 함께 홍삼복용 전 후에 걸쳐 안정시, 운동직 후, 그리고 회복기 30분의 MDA수준이 유의하게 낮아진 것으로 나타났다. 따라서 홍삼복용은 젊은이들뿐만 아니라 노인들의 축적된 과산화지질을 제거하거나 과산화지질의 생성을 억제하는 항산화 효과가 있음을 시사한다.
This study was performed to investigate the effect of 12 weeks red-ginseng intaking on MDA(malondialdehyde) produced during aerobic exercise in the young and elderly women. Sixteen volunteers agreed to participate and were placed in 2 groups: in the young(20-25 yrs), red-ginseng intake group(n=8), in the elderly(60-69 yrs), red-ginseng intaking group(n=8). The subjects who joined this study were asked to take 2.7g of red-ginseng powder capsule per day before the meal for 12 weeks(3 times/day). MDA(from blood samples) were collected at rest, just after the submaximal exercise, and 30 minutes after the exercise(cycle ergometer riding) at the beginning and the end of the 12-weeks program. After 12 weeks of red-ginseng intaking, young and elderly groups showed the decreased MDA significantly at rest(41.57%, 28.59%), just after the exercise(45.96%, 40.74%). and 30 minutes after the exercise(37.37%, 32.68%). These results indicate that red-ginseng intaking, as an antioxidant, may be useful for removing MDA produced during aerobic exercise in the elderly.
