The supplementation of conjugated linoleic acid (CLA) has positive effects in obese and does not promote amendment on body composition in healthy subjects practitioners of physical activity
Abstract
Objective: The present study has the objective of reviewing the scientific literature found in Medline, Scielo and Lilacs about principal effects of CLA in physical activity practitioners. Literature Review: Most of studies related to CLA are focused on its results between groups of obese – BMI ≥ 30 Kg/m). Recent studies indicates that CLA supplementation in obese people for 12 week, with a minimal dose of 3.4 g/d, showed positive results in anthropometric measurements as weight, BMI and Body Fat. Following other line of studies, the alternative use of CLA enriched foods showed no significant results in anthropometric variables. Finally, when supplemented with 3.0 and 6.0 g/dia, healthy subjects practitioners of physical activity had no significant results related to body composition. Beside this, most studies obtained worries results related to serum lipid profiles such as increased Total Cholesterol, LDL and decreased HDL in supplemented subjects. Conclusion: Based on Body Compo-sition, CLA supplementation has no effects in healthy exercised individuals. What has been proved is a positive function in the lost - and not in the prevention of weight gain in overweight and obese people supplemented with 3.4 g/d, for at least twelve weeks. Beside positive effects, it is important to consider its injuries on lipid profile.
