Abstract

To investigate the effects of conjugated linoleic acid (CLA) and/or exercise on body fat mass and weight, college women of normal weight (2130%) were recruited for this study. The participants were divided into 4 groups: placebo-no exercise, placebo-exercise, CLA-no exercise, and CLA-exercise groups. Three grams of either a placebo (corn oil) or CLA were taken every day for 12 weeks, and the exercise groups performed 80 minutes of aerobic and anaerobic exercise three times a week for 12 weeks. There were no differences in nutrient intakes among the groups. The CLA-exercise group had significantly lower body weight, BMI and body fat mass compared to the placebo-no exercise group. In addition, the HDL-cholesterol levels of subjects in the CLA-no exercise and CLA-exercise groups significantly increased compared to those in the placebo-no exercise group. These results suggest that a combination of CLA supplementation with exercise could efficiently reduce body fat mass and body weight compared to CLA supplementation or exercise alone.

체중이 정상이면서 체지방률 함량이 30% 이상인 여성을 대상으로 CLA 보충과 운동 여부가 체지방함량과 체중 및 혈당, 혈중 지질 농도에 미치는 영향에 대하여 살펴 본 결과는 다음과 같다. 실험 대상자들의 평균 연령은 22세였으며, 실험이 진행되는 동안 대상자들은 식이 조절을 하지 않았다. 실험 대상자들의 실험 후 체중과 BMI, 체지방 함량의 변화를 살펴본 결과, CLA-운동군이 placebo-비운동군에 비해 체중과 BMI가 유의적으로 작았으며, 체지방 함량도 적은 것으로 나타났다. 또한, 복부지방을 나타내는 허리둘레도 CLA-운동군이 placebo-비운동군과 비교하여 유의적으로 감소하여 CLA를 섭취하고 운동을 하는 것이 운동을 하거나, CLA만 섭취하는 것보다 체중 조절에 더 효과적인 것으로 나타났다. 대상자들의 평균 공복혈당, TG, total cholesterol, LDL-C, HDL-C은 모두 정상 범위에 속하였고, CLA를 섭취하거나 운동을 하는 경우 혈중 HDL-콜레스테롤의 함량을 증가시키는 것으로 나타났으나, CLA와 운동을 병행하는 경우 상승효과를 보이지는 않았다. 이러한 결과, CLA를 보충함으로써 체중 조절을 하는 것보다는 CLA와 운동을 함께 병행하는 것이 체중 조절에 효과적이며, 혈중 지질 농도를 개선시킬 수 있을 것으로 사료된다.
