Interval walking training has demonstrated more pronounced positive effects on physical fitness and metabolism in type 2 diabetes (T2D), compared to continuous walking. One of the pathogenic mechanisms of T2D is associated with derangements in leptin/adiponectin axis, which might predispose affected individuals to vascular inflammation and albuminuria. The aim of this study was to investigate the effects of interval walking training delivered through smart mobile devices upon albuminuria and leptin/adiponectin ratio in patients with T2D.
Patients with T2D aged 35-75 were randomized into control (n = 26) and interval training (IT, n = 14) groups. Patients in IT group had to perform three 60-min interval walking sessions (3 min intervals of slow and fast walking with the intensity of 40% and 70% of the peak energy expenditure) per week delivered by smartphone application for four months. The adherence to training was monitored remotely. Outcome measures were albuminuria, leptin/adiponectin ratio, obesity indicators, and glycaemic control. Leptin and adiponectin concentration was measured in serum samples by Luminex technology.
In the IT group compared to control group, we observed a statistically significant decrease in albuminuria (p = .002) and leptin/adiponectin ratio (p = .01), as well as a decrease in HbA1c close to statistical significance (p = .09). In IT group, changes in leptin/adiponectin ratio correlated significantly with changes in hip circumference (p = .024).
Interval walking training is beneficial for vascular health in T2D via impact on albuminuria and leptin/adiponectin ratio.
与连续步行相比,间歇步行训练对 2 型糖尿病(T2D)患者的身体适应性和新陈代谢有更显著的积极影响。T2D 的一种发病机制与瘦素/脂联素轴的紊乱有关,这可能使受影响的个体易患血管炎症和白蛋白尿。本研究旨在探讨通过智能移动设备进行间歇步行训练对 T2D 患者白蛋白尿和瘦素/脂联素比值的影响。
将 35-75 岁的 T2D 患者随机分为对照组(n=26)和间歇训练组(IT 组,n=14)。IT 组患者每周需要通过智能手机应用程序进行三次 60 分钟的间歇步行训练(3 分钟的慢走和快走间隔,强度分别为峰值能量消耗的 40%和 70%),共进行四个月。训练的依从性通过远程监测。主要观察指标为白蛋白尿、瘦素/脂联素比值、肥胖指标和血糖控制。采用 Luminex 技术测量血清样本中的瘦素和脂联素浓度。
与对照组相比,IT 组患者的白蛋白尿(p=0.002)和瘦素/脂联素比值(p=0.01)明显下降,糖化血红蛋白(HbA1c)也接近统计学意义(p=0.09)。在 IT 组中,瘦素/脂联素比值的变化与臀围的变化呈显著相关(p=0.024)。
间歇步行训练通过对白蛋白尿和瘦素/脂联素比值的影响,对 T2D 的血管健康有益。
