快速健步走运动对老年2型糖尿病患者身体活动能力的影响

目的：探讨快速健步走运动对老年2型糖尿病（T2DM）患者糖代谢及身体活动能力各项指标的影响。方法将T2DM患者80例随机分为运动组及对照组，每组40例。对运动组患者进行为期16周的快速健步走运动训练，将运动前后糖代谢及身体活动能力各项指标进行对比。结果运动组运动前后体适能项目VO2max 、2 min原地踏步、6 min行走、30 s臂屈伸运动、抓背伸展运动、坐椅体前伸运动等6项测试指标比较差异有统计学意义（P＜0.05）；而坐站走、30 s连续坐椅站立测试2项指标值比较差异有统计学意义（P＜0.01）。对照组患者不进行运动训练，体适能各项指标无显著改善（P＞0.05）；运动组患者餐后2 h血糖下降明显（P＜0.05），糖化血红蛋白、空腹尿糖阳性率、餐后2 h尿糖阳性率比较差异有统计学意义（P＜0.01），空腹血糖、空腹胰岛素和餐后2 h胰岛素测试水平无显著变化（P＞0.05）。下肢肌力测试比较，运动组患者踝关节屈伸肌力量均有不同程度增长。结论快速健步走运动训练方案有利于改善T2DM患者糖代谢及活动能力。

Physical activity effected by fast walking in elderly patients with type 2 diabetic disease

Objective To evaluate the effects of fast walking exercise on the physical activity in elderly patients with type 2 diabetes （T2DM） in glucose metabolism and physical activity indicators. Methods 80 patients with T2DM were randomly divided into two groups：exercise group and the control group, 40 cases in each group. Exercise group performed on 16 weeks of fast walking, before the movement of glucose metabolism and physical activity indicators were compared. Results The experimental group iftness program VO2max before and after exercise, 30s arm lfexion and extension, 2min standing still, chair-reach, grab the back stretch, 6min walk, six test scores were signiifcantly increased （P〈0.05）. While continuous improvement 30s standing and sitting in the chair stand test results go two （P＆lt;0.01）. In the control group it had no signiifcant improvement after the test. Patients in the control group iftness body each index changed little （P〉0.05）. 2h postprandial blood glucose （2hPG） decreased significantly （P〈0.05）, glycosylated hemoglobin （HbAlc）, postprandial 24h urine positive rate, fasting urine positive rate was signiifcantly lower （P〈0.01） fasting plasma glucose （FPG）, fasting insulin （Flns） and 2h postprandial insulin （2hIns） levels did not change signiifcantly （P〈0.05）. Lower extremity muscle strength tests comparing exercise group had ankle flexion and extension muscle strength growth to varying. Conclusion Fast walking exercise training program will help to improve glucose metabolism and activity in patients with T2DM.
