The Impact of Burst Exercise on Cardiometabolic Status of Patients Newly Diagnosed With Type 2 Diabetes

摘要

Abstract Background The impact of burst high-intensity exercise on physiological, cardiometabolic, and biochemical variables compared with traditional moderate-intensity continuous exercise training (MICT) has yet to be assessed in patients with type 2 diabetes (T2D). We compared the impact of multiple short-duration, high-intensity burst exercise sessions to MICT on cardiometabolic variables in patients with T2D. Methods Forty newly diagnosed patients with T2D not receiving lipid lowering or hypoglycemic medications were randomized to 40 minutes of MICT (60% of maximal heart rate) 5 days per week or 3 continuous bursts of 12 minutes of high-intensity exercise (85% of maximal heart rate) 5 days per week for 3 months. Body mass index, hemoglobin A 1C (HbA 1C ), and lipid profile were assessed before and after 3 months of exercise training. Results Burst exercise resulted in greater body mass index reduction than did MICT (–2.1 ± 1.2 kg/m 2 vs –0.7 ± 0.7 kg/m 2 , respectively; P P 1C levels in the burst exercise group (8.14% ± 0.49% to 7.32%?±?0.39%) compared with the MICT group (8.18% ± 0.35% to?7.94% ± 0.41%). Compared with MICT, burst exercise was associated with a greater reduction in low-density lipoprotein cholesterol (–11?vs?–4%; P P P Conclusions Findings from the current study support better cardiometabolic benefits of burst exercise compared with MICT over 3 months in patients with newly diagnosed T2D.
