Effect of hydration with carbohydrates on the glycemic response in type I diabetics during exercise

Não está claro se a ingestão de carboidratos (CHO) através de bebidas esportivas pode manter a glicemia em diabéticos tipo 1. A finalidade deste estudo foi examinar a glicemia em adolescentes com diabetes tipo 1 que ingeriram bebidas esportivas com 6% de CHO durante e após o exercício. Dez adolescentes (5 meninas e 5 meninos, 15,3 ± 2,4 anos) com o diabetes controlado (HbA1c 0,05), e diminuiu significativamente na situação placebo (282,9 ± 85 para 160,2 ± 77mg•dL-1, p 0,05), y disminuyó significativamente en la situación placebo (282,9 ± 85 para 160,2 ± 77 mg•dL-1, p 0.05) as it did in the placebo situation (282.9 ± 85.1 to 160.2 ± 77.0 mg• dL-1, p < 0,05) (9 vs 43.2%). After 30 min of recovery, blood glucose concentrations were 177.2 ± 107 mg•dL-1 with CHO-6% and 149.1 ± 69.6 mg•dL-1 in the placebo situation, representing 20.1% and 47.3% of pre-exercise levels. No significant differences between situations were found in heart rate, rate of perceived exertion or in blood insulin and electrolytes levels. No changes in hematocrit and hemoglobin were found during exercise, indicating that subjects remained euhydrated. In conclusion, the use of drinks containing 6% of CHO was shown to attenuate the exercise-induced reduction of blood glucose concentration in adolescents with type I diabetes
