Metformina como recurso ergogênico associada à suplementação de carboidrato sobre a capacidade anaeróbia

Abstract

Carbohydrate (CHO) intake has been used as a way to improve sports performance. Some researches indicate that CHO supplementation on anaerobic exercise causes no ergogenic effects. However, other authors claim that the CHO can be an important energy source for intense activities and short duration when administered at high concentrations. Metformin is used by diabetics as an oral antihyperglycaemic. Its mechanisms involve decreased hepatic glucose production and increased glucose uptake by skeletal muscle. Studies have associated with the intake of metformin exercise, intending to maximizing its effects. To contribute to the discussion of the problem, this study presents three articles: 1) A systematic review article which discusses the effects of carbohydrate intake on improving anaerobic capacity. In additional, also addresses metformin associated with exercise, demonstrating the effects of reducing blood glucose and decreased body weight; 2) An experimental paper in order to observe the effects of the intake of metformin alone and associated with carbohydrate supplementation on a classical method to estimate the anaerobic capacity (MAOD); 3) An experimental paper in order to observe the effects of the intake of metformin alone and associated with carbohydrate supplementation on an alternative method to estimate the anaerobic capacity (MAODALT)
