Influence of carbohydrate supplementation upon glucose and cortisol levels in the military march
Abstract
The goal of this research was evaluate the effect of carbohydrate suplement related to glycemic control and cortisol level of Brazilian army soldiers submited to 16Km military march. For such purpose, it was made a 16Km walking from medium to higer intensity. The soldiers were divided in 2 groups and suplemented with placebo and carbohydrate. A blood collection was made before and immediately after the march in both groups. The glucose and cortisol concentration were determined by enzymatic and radio-immune assays respectively. The results were anlyzed statisticlly using ANOVA and Post-Hoc the Tukey Test witer 0.05% significance level. The results show that carbohydrate supplementation facilitates the glycemic control and also attenuates the rise of cortisol during the 16 km military march.
