Impact of Different Types of Exercise Training on Biochemical Markers of Insulin-dependent Patients

Background: Type 1 diabetes mellitus (T1DM) is characterized by the destruction of β cells and consequent loss of insulin secretion due an autoimmune process, being associated with increased cardiovascular risk, oxidative stress and inflammation. Considering that most people with T1DM do not reach recommended levels of physical activity due to concern about the rapid drop in blood sugar and the excuse of "lack of time", shorter sessions of exercise that provide several benefits should be encouraged. Thus, this work aims to compare the effects of high-intensity interval training (HIIT), strength training (ST) and both interventions on several blood markers and functional parameters in T1DM patients. Study hypothesis: (1) ST+HIIT will be more beneficial than HIIT, which in turn will be more beneficial than ST, on modification of blood levels of pro and anti-inflammatory, pro and antioxidant, lipid, renal and glucose metabolism parameters and (2) ST+HIIT will be more beneficial than HIIT, which in turn will be more beneficial than ST, on modification of functional parameters, body composition and maximal oxygen uptake.
