Abstract

Background and Objective: Diabetes type 2 has been estimated as the seventh leading cause of death worldwide. Diabetic patients are 2-3 times more likely to be at the risk of atherosclerosis, compared to normal people. It has been reported that exercise prevents atherosclerosis in diabetic patients. Therefore, the aim of this study was to investigate the effect of exercise on vascular variables of patients with type 2 diabetes. Materials and Methods: This clinical trial was conducted on 40 patients out of 702 volunteers with diabetes who were randomly assigned into two groups of combined (aerobic and resistance) and control. The intervention protocol included 24 30-min sessions of aerobic exercise on the treadmill without any slope during 8 weeks (three sessions per week). The protocol intensity was set at 50-70% maximum heart rate and volunteers wore a weighted vest during exercise. On the other hand, the control group had no exercise for two months. All variables were measured before the intervention and after 24 sessions of the intervention protocol. Results: According to the results, there were no differences between the groups regarding demographic characteristics and a history of type 2 diabetes before the intervention. After 24 sessions, there was a significant decrease in the intima-media thickness. Moreover, the ratio of the intimamedia thickness to the lumen in three sections of Carotid Bulb, Internal Carotid, and Common Carotid was significantly reduced in the combined exercise group, compared to the control group (P<0.05); however, no significant difference was observed in the lumen diameter (P>0.05). All vascular parameters remained unchanged in the control group (P>0.05). Conclusion: In total, 24 sessions of aerobic and resistance exercise had a positive effect on vascular parameters. According to the simulation of a backpack by a weighted vest, the method used in this study was considered as a cheap and useful technique for patients with type 2 diabetes.

2型糖尿病患者有氧和阻力联合运动24次后颈动脉内膜-中膜厚度降低
背景和目的:2型糖尿病已被估计为全球第七大死因。糖尿病患者患动脉粥样硬化的风险是正常人的2-3倍。据报道,运动可以预防糖尿病患者的动脉粥样硬化。因此,本研究的目的是探讨运动对2型糖尿病患者血管变量的影响。材料与方法:本临床试验选取702名糖尿病志愿者中的40名患者,随机分为两组(有氧组和抵抗组)和对照组。干预方案包括连续8周在无坡度的跑步机上进行24次30分钟的有氧运动(每周3次)。协议强度设定为最大心率的50-70%,志愿者在运动期间穿着加权背心。另一方面,对照组两个月没有锻炼。在干预前和干预方案的24个疗程后测量所有变量。结果:根据结果,两组在人口统计学特征和干预前的2型糖尿病病史方面没有差异。24个疗程后,内膜-中膜厚度显著降低。与对照组相比,联合运动组颈动脉球段、颈内动脉段、颈总动脉段的内膜厚度与管腔的比值显著降低(P0.05)。对照组血管参数无明显变化(P < 0.05)。结论:24次有氧和阻力运动对血管参数有积极影响。根据加重背心对背包的模拟,本研究中使用的方法对于2型糖尿病患者来说是一种廉价且有用的技术。
