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 0.05) 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.Na intenção da redução de peso em obesos, algumas estratégias relacionadas a atividade física e uso de bioativos vem sendo utilizadas. Objetivo: Relacionar a perda de peso de mulheres praticantes de treinamento resistido com o uso do picolinato de cromo. Tratou-se de um ensaio clínico randomizado e controlado por placebo envolvendo 30 mulheres, com IMC acima de 25Kgm² e praticantes regulares de treinamento de resistência. As participantes foram divididas em dois grupos, sendo G1 (experimental) e G2 (controle), de forma aleatória para recebimento da suplementação por 30 dias. Todas as participantes foram submetidas ao mesmo protocolo de treino, o qual foi elaborado e acompanhado por um educador físico. Um dia antes e um dia após o período da suplementação foram realizadas avaliações antropométricas e verificado o recordatório alimentar. Para análise estatística, foram utilizados os testes Mann Whitney e t pareado para comparação intragrupos e Wilcoxon e t indepedente para comparação intergrupos. Quando feita a comparação intragrupos, pré e pós intervenção, foi observado, no G1, uma diferença estatística significativa no peso corporal, IMC, CC, CQ e %G (p0,05) em nenhuma variável. Através deste estudo pode-se concluir que o uso da suplementação por 30 dias de 400mcg de picolinato de cromo, não contribui para a redução da gordura corporal em mulheres com sobrepeso obesidade praticantes de treinamento de resistência. ABSTRACT Relationship of chromium picolinate supplementation with weight loss in womenIn the intention of reducing weight in obese, some strategies related to physical activity and use of bioactive have been used.
