This study compared the acute effects of a session of different high-intensity interval exercise (HIIE) protocols and a session of moderate-intensity continuous exercise (MICE) on blood glucose, blood pressure (BP), and heart rate (HR) in people with Type 2 Diabetes Mellitus (DM2). The trial included 44 participants (age: 55.91 ± 1.25 years; BMI: 28.95 ± 0.67 kg/m²; Hb1Ac: 9.1 ± 2.3%; 76 mmol/mol) randomized into three exercise protocols based on the velocity at which maximum oxygen consumption was obtained (vVO2 max): long HIIE (2 min at 100% vV̇o2peak + 2 min of passive rest); short HIIE (30 s at 100% vV̇o2peak + 30 s of passive rest); or MICE (14 min at 70% vV̇o2peak) on a treadmill. Capillary blood glucose, BP, and HR measurements were taken at rest, during peak exercise, immediately after the end of exercise, and 10 min after exercise. Long and short HIIE protocols reduced capillary blood glucose by 32.14 mg/dL and 31.40 mg/dL, respectively, and reduced systolic BP by 12.43 mmHg and 8.73 mmHg, respectively. No significant changes were observed for MICE. HIIE was found to promote more acute effects than MICE on glycemia and BP in people with DM2.

Purpose: The present study aimed to report the effects of 15 weeks of a minimal dose resistance training on blood glucose levels, blood pressure, heart rate, physical capacity, and quality of life of a 67 old woman with type 2 diabetes mellitus, cardiopathy and hypertension. Method: The Patient was sedentary with a family history of heart failure and coronary artery disease. She suffered a heart attack in 2013 and was submitted to six cardiac catheterizations and one angioplasty between the 2015 and 2017. On April 2017, she was initially untrained in resistance training and was followed for 15 weeks with the performance of 31 resistance training sessions. Resistance training followed a minimal dose approach with 4 exercises performed with 2 sets to muscle failure, twice a week. Results: After follow up, the Patient presented a reduction in blood glucose, systolic and diastolic blood pressure, and heart rate at rest. There were also improvements on body mass index, cardiorespiratory fitness and quality of life. These results were accompanied by a reduction in the amount of antihypertensive and anti-diabetic medications. Conclusions: These results suggest that only 40 min of resistance training per week might help to improve general health and quality of life in a patient with hypertension and type 2 diabetes mellitus.
