步行训练对老年2型糖尿病患者肺功能及血糖的影响

Influence of waling training on pulmonary function and blood glucose in aged patients with type 2 diabetes mellitus

目的:探讨步行训练对老年2型糖尿病患者肺功能及血糖的影响。方法:选择我院内分泌科收治的163例2型糖尿病患者,按数字列表法随机分为常规组(80例,严格按照糖尿病饮食和常规胰岛素治疗,并按往常生活习惯正常生活),强化组[83例,在严格糖尿病饮食和常规胰岛素治疗的基础上再进行步行强化训练(即步行量≥10000步/d)],训练8周,比较分析两组患者干预前后心肺功能及血糖指标。结果:强化组治疗后较治疗前肺功能明显提高、血糖各指标明显降低(P均<0.01);且与常规组比较,强化组治疗后肺活量[(2622.0±323.3)ml比(2987.0±405.6)ml]、第一秒用力呼气量[(2003.0±279.7)ml比(2392.0±323.6)ml]、肺活量/体重比值[(44.0±4.2)ml/kg比(47.0±4.7)ml/kg]明显增加,糖化血红蛋白[(5.63±2.63)mmol/L比(3.82±1.41)mmol/L]、空腹血糖[(7.90±1.41)mmol/L比(5.28±1.18)mmol/L]、餐后2h血糖[(10.48±1.43)mmol/L比(8.09±1.68)mmol/L]明显降低(P均<0.01)。常规组治疗前后无明显差异(P>0.05)。结论:步行训练作为低强度有氧运动,能有效提高老年2型糖尿病患者肺功能,改善糖的代谢,有助于改善生活质量。

Objective： To explore influence of walking training on pulmonary function and blood glucose in aged patients with type 2 diabetes mellitus （T2DM）. Methods： A total of 163 T2DM patients treated in our department were selected. According to number table, they were randomly divided into routine group （n = 80, performed DM diet and routine insulin therapy strictly, and lived as usual） and intensive group （n = 83, received intensive walking training based on strict DM diet and routine insulin therapy, namely walking ≥10000 steps/d for eight weeks）. Pulmonary function and blood glucose indexes were compared between two groups before and after intervention. Results： Compared with before treatment, after treatment, there was significant rise in pulmonary function and significant reductions in blood glucose indexes in intensive group, P〈0.01 all; compared with routine group after treatment, there were significant rise in vital volume [（2622.0± 323.3）ml vs. （2987.0 ± 405.6）ml], forced expiratory volume in one second [（2003.0±279.7）ml 比 （2392.0 ±323.6）ml]and vital volume/body weight [（44.0 ± 4.2） ml/kg vs. （47.0 ± 4.7） ml/kg], and significant reductions in levels of glycosylated hemoglobin Alc [（5.63 ±2.63）mmol/L vs. （3.82 ± 1.41） mmol/L], fasting blood glucose [（7.90± 1.41） mmol/L vs. （5.28± 1.18） mmol/L]and 2h postprandial blood glucose [（10.48 ± 1.43） mmol/L vs. （8.09 ± 1.68） mmol/L]in intensive group, P〈0.01 all. Compared with before treatment, there were no significant changes in above indexes in routine group after treatment, P〉 0.05. Conclusion： As a low intensity aerobic exercise, walking training can effectively improve pulmonary function, glucose metabolism in aged patients with type 2 diabetes mellitus,it is help to improve quality of life.
