Relação da suplementação de picolinato de cromo com a perda de peso em mulheres

Abstract

In the intention of reducing weight in obese, some strategies related to physical activity and use of bioactive have been used. Objective: To relate the weight loss of women practicing resistance training with the use of chromium picolinate. This was a randomized, placebo-controlled trial involving 30 women, with a BMI above 25Kg m 2 and regular resistance training practitioners. The participants were divided in two groups, being G1 (experimental) and G2 (control), in a random way to receive the supplementation for 30 days. All participants were submitted to the same training protocol, which was elaborated and accompanied by a physical educator. One day before and one day after the supplementation period, anthropometric assessments were performed and the food recall was verified. For statistical analysis, the Mann Whitney and t paired tests were used for intragroup and Wilcoxon comparisons, and t was independent for intergroup comparisons. When comparing intragroups, pre and post intervention, a significant statistical difference in body weight, BMI, CC, CQ and% G (p <0.001) was observed in G1. Group G2, only fat percentage presented statistical difference (p <0.000). When comparing intergroups, pre and post intervention, no statistical difference (p> 0.05) was observed in any variable. Through this study it can be concluded that the use of 30-day supplementation of 400mcg of chromium picolinate does not contribute to the reduction of body fat in overweight obese women practicing resistance training.
