In recent years various studies have emerged on the supplementation of conjugated linoleic acid is a polyunsaturated fatty acids. This study was motivated in order to use the CLA, which gained popularity with promises to produce effects in the reduction of lean body mass.

After a period of 62 days, the rat were sacrificed and was withdrawing the liver, spleen and kidney, to analyze the amount of fat tissue. The rest of the carcass was homogenized mouse to perform the analysis of the percentage of fat in rats. Based on the profile of body composition observed in the sample studied, it was possible to identify that the rats supplemented with conjugated linoleic acid had a significant reduction in percentage of fat when compared to the PLA group (51,52 0,03). When with the CLA (42,26 0,007) correlate the percentage of fat in the group CLAEX (34,14 0,01), it was noted a further decrease in the percentage of fat group in rats, demonstrating that the exercise involved supplementation led to greater reduction of body fat than supplementation alone.
