CARDIOVASCULAR DISEASES, DYSLIPIDEMIA
The present study investigated the effects of three aerobic training protocols (L- HIIT, S-HIIT, and MICT) on cardiometabolic parameters of patients with T2DM. The recommendation of a minimum of 150 min per week of moderate intensity physical activities for blood glucose control and cardiovascular health is still predominant (Previous studies have shown 15 to 20% reductions in cardiovascular events when HbA1c is reduced by 1% (Although no significant difference was found for lipid profile between groups, there was a trend to decrease triglycerides and a large effect was found between pre and post intervention for both HIIT protocols [L-HIIT [-0.57 (wide)]; S-HIIT [-0.53 (wide)]. It is important to acknowledge that improvements in triglyceride and HDL levels are important due to the associations between dyslipidemia and cardiovascular diseases (L-HIIT showed a greater reduction in resting SBP when compared to MICT (p = 0.018; d = 1.56 [large effect]). Although several studies have shown BP reductions through exercises (One important limitation of the present study is the absence of dietary control. However, participants were oriented to not change their diet. We believe that these limitations do not prevent the conclusions of the study from being elaborated. In addition, due the lack of control group, it was not possible to know whether changes observed for exercising groups were different when compared to non-exercise conditions.
