等热卡不同运动方式糖尿病患者代谢因素和心血管反应的研究

Effects of different exercises with isocaloric consumes on metabolic factors and cardiovascular responses in type 2 diabetic patients

目的:探讨等热卡消耗的情况下不同运动方式对糖尿病患者代谢因素和心血管反应的影响,以利于糖尿病患者个体化运动处方的制订。方法:13例2型糖尿病患者采用活动平板和功率车两种运动方式,使用气体代谢分析仪器进行等热卡消耗运动方案,监测运动中血糖、心率、血压及气体代谢等指标。结果:在热卡消耗相等的情况下,两种方式运动前后患者血糖均显著降低,血糖下降差值无显著性变化;VE/VO2、VE/VCO2和运动中靶心率存在显著性差异。结论:等热卡不同方式的运动降糖效应和心血管效应相似,运动方式并不是糖尿病患者血糖控制的决定因素。

Objective：To explore the effects of different exercises with isocaloric consumes on metabolic factors and cardiovascular responses in order to provide individually exercise prescriptions for type 2 diabetic patients.Method： Thirteen patients with type 2 diabetes were included for this exercise programs of isocaloric consumes with motorized treadmill and cycle ergometer respectively by gas exchange analyzers（k4b^2）.The blood glucose,heart rate,blood pressure and gas exchange parameters were monitored during exercises.Result：The levers of blood glucose after exereise decreased significantly compared with that pre-exercise. There were not significantly differences in the reductions of blood glucose between treadmill and ergometer with isocaloric consumes,but there were significantly differences in VE/VO2.VE/VCO2 and target heart rate between different exercises.Conclusion：The effects of different exercises with isocaloric consumes on metabolic factors and cardiovascular responses are homologous,which suggests that the exercise form be not a crucial factor to adjust the levels of blood glucose in type 2 diabetic patients,and provide a new idea for quantity of exercise prescription by use of isocaloric consumes in type 2 diabetic patients.
