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.
