Resumo: | Carbohydrate is an important source of energy which is stored as glycogen. Since this storage may be related to the use of sports drinks, this study evaluated the changes in liver, skeletal muscle and kidney glycogen content of rats supplemented with maltodextrin and submitted to aerobic exercise at maximum lactate steady state or high intensity anaerobic exercise. Sixty-nine male Wistar rats, 60 days old at the beginning of the experiment, were used. The training protocol consisted of 8 weeks of continuous aerobic (60 min/day) or intermittent swimming (two periods of 30 min/day at an interval of 10 min and an exercise/rest ratio of 15 seconds), with overloads corresponding to 5% and 10% of body weight, respectively. The animals were supplemented for 37 days with a daily dose of 0.48 g/kg maltodextrin dissolved in water or received pure water. Factorial ANOVA or the Kruskal-Wallis test was used for data analysis. Aerobic training resulted in a significant increase in blood glucose (p˂0.02) and in a decline in hepatic glycogen content (p<0.02), while anaerobic exercise promoted a significant increase in lactate concentration (p<0.001) and a decrease in skeletal muscle (p=0.02) and kidney (p<0.03) glycogen content. Maltodextrin supplementation significantly increased muscle (p=0.008) and kidney (p<0.02) glycogen content in rats submitted to aerobic exercise. Eight weeks of aerobic and anaerobic exercise caused changes in liver, skeletal muscle and kidney glycogen content, as well as in blood glucose and blood lactate. Maltodextrin supplementation was effective in increasing skeletal muscle and kidney glycogen stores in rats submitted to aerobic exercise. |

Considerando que este armazenamento pode estar relacionado com o uso de soluções esportivas, este estudo verificou as alterações nos conteúdos de glicogênio hepático, muscular e renal de ratos suplementados com maltodextrina e treinados em exercício aeróbio no estado estável máximo de lactato ou anaeróbio de alta intensidade. Foram utilizados 69 ratos machos da linhagem Wistar, com 60 dias, no início do experimento. O protocolo de treinamento consistiu de oito semanas de natação em padrão aeróbio contínuo (60 min/dia) ou intermitente (dois períodos de 30 min, com intervalo de 10 min e relação esforço/pausa de 15 segundos), com sobrecargas correspondentes a 5% e 10% do peso corporal, respectivamente. Durante 37 dias, os animais foram suplementados com uma dose diária de 0,48 g/kg de maltodextrina dissolvida em água ou receberam água pura. Para a análise dos dados, utilizou-se a Anova fatorial ou o Teste de Kruskal-Wallis. O treinamento aeróbio ocasionou aumento na glicemia (p<0,02) e redução de glicogênio hepático (p<0,02), enquanto o exercício anaeróbio proporcionou aumento no lactato (p<0,001) e diminuição de glicogênio muscular (p=0,02) e renal (p<0,03). A maltodextrina causou elevação no conteúdo de glicogênio muscular (p=0,008) e renal (p<0,02) dos ratos exercitados em exercício aeróbio. Oito semanas de exercício aeróbio e anaeróbio proporcionaram importantes alterações nos conteúdos de glicogênio hepático, muscular e renal, assim como na glicemia e no lactato sanguíneo. A suplementação com maltodextrina foi efetiva em elevar o conteúdo de glicogênio muscular e renal de ratos exercitados em exercício aeróbio.Universidade Federal de Santa Catarina. Florianópolis, SC.
