- Abstract
The purpose of this study was to evaluate the chronic autonomic cardiac modulation and metabolic effects of 12 wks of long or short HIIT in adults with T2DM. Fifteen T2DM patients (52 ± 13,7 yrs) were submitted to 12 wks of intervention (24 sessions of 30 min). The sample was divided in 3 groups: (a) Short HIIT - 30 sec in 90%VO2peak, followed by 30 sec recovery; (b) Long HIIT - 120 sec in 85%VO2peak, followed by 120 sec recovery; and (c) Control Group - did not perform any exercise. We measured blood parameters, cardiopulmonary level, body composition, and heart rate variability (HRV) before and after 12 wks. The results demonstrated that long HIIT improved significantly the cardiac modulation and the VO2peak. Both exercise protocols improved significantly the glycemic control. This study indicates that long-HIIT is an interesting strategy to improve metabolic and cardiopulmonary functions, which can help to prevent the development of diabetic heart diseases in T2DM patients.
