Exercise as a Tool for Studying the Mechanisms and Applicability of Glycemic Variability

The aim this study is characterize glycemic variability using linear and nonlinear mathematical tools, under basal conditions and in response to specific protocols acute exercise that evoke oxidative stress and inflammation in healthy subjects and type 2 diabetes patients. For this purpose, the sample size will consist of 37 individuals healthy and 32 without type 2 diabetes mellitus wore a CGMS during 3 days. Participants randomly performed aerobic and eccentric sessions, both in the morning (24h after CGMS placement), and at least 7 days apart. Glucose variability was evaluated by glucose standard deviation, glucose variance, mean amplitude of glycemic excursions (MAGE), and glucose coefficient of variation (conventional methods) as well as by spectral and symbolic analysis (non-conventional methods). Physiological mechanisms altered by exercise protocols (Human Soluble Interleukin-6 and Glutathione), will be measured in blood samples.
