心肺运动试验在指导2型糖尿病患者精准化运动中的效果

The effect of cardiopulmonary exercise test in guiding precise exercise of patients with type 2 diabetes mellitus

目的:探索心肺运动试验在指导2型糖尿病患者精准化运动中的效果。方法:选择接受心肺运动试验的2型糖尿病患者60例,随机分为对照组和干预组,每组30例。对照组给予患者常规运动指导,干预组根据患者心肺运动试验结果给予精准化指导。运动3个月后,比较两组患者试验前后的糖化血红蛋白(HbA1c)、BMI、峰值摄氧量(VO2peak)、峰值氧脉搏(O2Pulsepeak)、无氧阈(AT)、峰值潮气量(VTpeak)结果,统计患者运动过程中不良事件发生情况。结果:3个月后与基线比较,对照组患者HbA1c、BMI、O2Pulsepeak、VTpeak的变化有显著差异(P<0.05),VO2peak、AT的变化无差异(均P>0.05),干预组所有数值变化显著(均P<0.05);干预组除HbA1c(P>0.05)外,其余数值较对照组改善程度明显(P<0.05);不良事件中,两组患者低血糖的发生无差异(P>0.05),对照组心脏危险事件明显高于干预组(均P<0.05)。结论:两种运动方式均能降低患者血糖水平,但是根据心肺运动试验结果指导2型糖尿病患者的精准化运动,更能有效提高患者心肺功能,减少运动过程中不良事件发生率。

Objective:To explore the effect of cardiopulmonary exercise test in guiding the precise exercise of patients with type 2 diabetes mellitus.Methods:After receiving cardiopulmonary exercise test,60 patients with type 2 diabetes mellitus were randomly divided into intervention group and control group,30 cases in each group.The control group were received routine exercise guidance,and the intervention group were received precise guidance according to the results of cardiopulmonary exercise test.The results of glycosylated hemoglobin(HbA1c),BMI,peak oxygen uptake(VO2peak),peak oxygen pulse(O2Pulsepeak),anaerobic threshold(AT)and peak tidal volume(VTpeak)were compared between the two groups after 3 months of exercise.The incidence of adverse events during exercise was counted.Results:Compared with baseline after 3 months,the changes of HbA1c,BMI,O2Pulsepeak and VTpeak in the control group were significantly different(P<0.05),but the changes of VO2peak and AT were not different(all P>0.05).All indicators in the intervention group were significantly different(all P<0.05).All indicators in the intervention group were significantly better than those in the control group(P<0.05),except HbA1c(P>0.05).There was no significant difference in the occurrence of hypoglycemia between the two groups(all P>0.05),but the cardiac risk events in the control group were significantly higher than those in the intervention group(all P<0.05).Conclusion:Both exercise methods can reduce the blood glucose level of patients,but according to the results of cardiopulmonary exercise test to guide the precise exercise of patients with type 2 diabetes mellitus,it can effectively improve the cardiopulmonary function of patients and reduce the incidence of adverse events during exercise.
