Description
Summary:Introduction: Obesity is a major risk factor for metabolic syndrome. This syndrome comprises a group of conditions including insulin resistance, diabetes type two and hypertension. Obese individuals may develop in parallel insulin resistance with obesity, while it remains normal glucose tolerance, the pancreatic beta cells to increase production and secretion of insulin as a compensatory mechanism. Studies have shown positive effects of caffeine and L-arginine on the reduction in glucose tolerance and increased insulin sensitivity. Methods: We used 10 adult male Wistar rats, 4-month-old boy with obesity induced by monosodium glutamate (MSG). We conducted a swim test lasting 30 minutes and measured blood glucose levels before and after exercise and supplementation. Results: The animals that received caffeine reduced (14%), for L-Arg was reduced to L-Arg was reduced (10%) or placebo (65%). Conclusion: The results showed that acute caffeine intake could be modifying the availability or glucose metabolism in obese mice along with exercise, however these data should be supplemented in the new study however try to follow the results of studies in the literature. Key Words: Obesity, Caffeine, L-arginine, Glucose, Exercise. Introducao: A obesidade e um dos principais fatores de risco para a sindrome metabolica. Essa sindrome engloba um grupo de patologias que incluem a resistencia a insulina, hipertensao e a diabetes tipo 2. Individuos obesos podem desenvolver a resistencia a insulina paralelamente a obesidade, pois enquanto a tolerancia a glicose permanece normal, as celulas G pancreaticas aumentam a producao e secrecao de insulina como um mecanismo compensatorio. Estudos mostram efeitos positivos da cafeina e da L-Arginina sobre a reducao da tolerancia a glicose e do aumento da sensibilidade a insulina. Metodos: Foram utilizados 10 ratos adultos Wistar, com 4 meses de idade, com quadro de obesidade induzido por glutamato monossodico (MSG). Foi realizado um teste de natacao com duracao de 30 minutos e medido os niveis glicemicos antes e apos exercicio e suplementacao. Resultados: Os ratos que receberam cafeina reduziram (14%), para a L-arg teve reducao de para a L-arg teve reducao de (10%) ou placebo (65%). Conclusao: Os resultados mostraram que a ingestao de cafeina aguda parece modificar a disponibilidade ou metabolismo da glicose em ratos obesos juntamente com o exercicio.
