Diabetes is a chronic disease that reduces cardiorespiratory fitness and increases systolic and diastolic blood pressures as well as resting heart rate due to the activity level of the sympathetic nervous system. The aim of this study was to assess the effectiveness of 2 types of aerobic exercise, with and without external loading, on cardiac parameters in diabetic patients. : This randomized controlled trial was carried out on 45 volunteers. These individuals were randomly divided into aerobic, weighted vest, and control groups. The aerobic protocol comprised 24 sessions of aerobic exercise. The exercise program for the weighted vest group was identical to that of the aerobic group, except that the subjects wore a weighted vest. The parameters were measured before and after the 24 sessions. : The mean age of the study population was 48.30±5.02 years in the aerobic group, 48.33±5.74 years in the weighted vest group, and 48.60±4.79 years in the control group. Males comprised 7 (53.8%) patients in the aerobic group, 7 (58.3%) in the weighted vest group, and 8 (53.3%) in the control group. After 8 weeks, maximum oxygen consumption in the aerobic group (mean±SD=37.54±8.02 mL/kg/min, 95% CI: 5.48 to 11.60; P<0.001) and the weighted vest group (mean±SD=35.92±3.96 mL/kg/min, 95% CI: 4.36 to 9.64; P<0.001) was increased, similar to metabolic equivalent of task in the aerobic group (mean±SD=11.60±1.62 kcal/kg×h, 95% CI: 1.48 to 2.72; P<0.001) and the weighted vest group (mean±SD=11.21±1.11 kcal/kg×h, 95% CI: 1.23 to 2.28; P<0.001). Furthermore, resting heart rate decreased significantly in the aerobic group (mean ± SD=90.23±8.90 bpm, 95% CI: -13.93 to -1.29; P=0.022) and the weighted vest group (mean±SD=90.58±9.19 bpm, 95% CI: -0.16 to - 12.33; P=0.045). : These findings suggest that 24 aerobic exercise sessions might improve cardiac parameters in type 2 diabetes.
糖尿病是一种慢性疾病，由于交感神经系统的活动水平，它会降低心肺适能，升高收缩压和舒张压以及静息心率。本研究的目的是评估两种有氧运动（有无外部负荷）对糖尿病患者心脏参数的有效性。：这项随机对照试验对45名志愿者进行。这些个体被随机分为有氧运动组、负重背心组和对照组。有氧运动方案包括24节有氧运动课程。负重背心组的运动计划与有氧运动组相同，只是受试者穿着负重背心。在24节课程前后测量各项参数。：有氧运动组研究人群的平均年龄为48.30±5.02岁，负重背心组为48.33±5.74岁，对照组为48.60±4.79岁。有氧运动组男性有7名（53.8%），负重背心组有7名（58.3%），对照组有8名（53.3%）。8周后，有氧运动组的最大耗氧量（均值±标准差=37.54±8.02毫升/千克/分钟，95%置信区间：5.48至11.60；P<0.001）和负重背心组（均值±标准差=35.92±3.96毫升/千克/分钟，95%置信区间：4.36至9.64；P<0.001）增加，有氧运动组的代谢当量（均值±标准差=11.60±1.62千卡/千克×小时，95%置信区间：1.48至2.72；P<0.001）和负重背心组（均值±标准差=11.21±1.11千卡/千克×小时，95%置信区间：1.23至2.28；P<0.001）也类似。此外，有氧运动组（均值±标准差=90.23±8.90次/分钟，95%置信区间：-13.93至-1.29；P=0.022）和负重背心组（均值±标准差=90.58±9.19次/分钟，95%置信区间：-0.16至-12.33；P=0.045）的静息心率显著降低。：这些发现表明，24节有氧运动课程可能会改善2型糖尿病患者的心脏参数。
