八段锦对2型糖尿病患者下肢肌力与身体成分的影响

Effect of regular Baduanjin exercise on lower limb strength and body composition in patients with type 2 diabetes mellitus

[目的]观察规律性八段锦运动对2型糖尿病患者的血糖、下肢肌力与身体成分的影响。[方法]选取60例2型糖尿病患者，年龄45—67岁之间，随机分为八段锦运动干预组与对照组，分别给予12周八段锦运动（45～50分／次，5次／周）与糖尿病的病因、防治及饮食等教育（90分／次，1次／月）。比较两组空腹血糖、餐后血糖、糖化血红蛋白、股四头肌、胭绳肌、胫骨前肌与腓肠肌最大等长肌力，体脂百分比与腰臀比。[结果]组内比较八段锦运动干预组，患者的空腹血糖、餐后血糖、糖化血红蛋白与运动前相比均降低，差异有统计学意义（P〈0．05）；干预后与对照组相比，差异有统计学意义（P〈0．05）。女性体脂百分比下降，差异有统计学意义（P〈0．05）；且与对照组相比，差异有统计学意义（P〈0．05）。与本组干预前相比较，双侧股四头肌、胫骨前肌、腓肠肌最大等长肌力均增长，依次平均增长6．7kg（增长率19．8％）、6．5kg（增长率24．3％）、6．0kg（增长率24．7％），均P〈O．05，与对照组相比，干预后，股四头肌、胫骨前肌与腓肠肌肌力增加，均P〈0．05。[结论]12周规律性八段锦运动有效改善2型糖尿病患者的血糖、身体成分与肌肉力量，可为进一步研究传统体育运动八段锦防治糖尿病及其并发症如糖尿病足等提供基础。

[Objective] To observe the effect of regular Baduanjin exercise on the level of blood glucose control, body composition and lower limb strength in patients with type 2 diabetes mellitus （T2DM）. [Methods] The 60 T2DM patients, aged from 45 to 67 years old, were enrolled in this study. They were randomly divided into two groups,Baduanjin exercise group and control group. Patients in Baduanjin exercise group did Baduanjin exercise for 12 weeks,45-50 min each time, 5 times a week. Patients in control group received diabetes education,once a month. Fasting blood-glucose （FBG）, postprandial blood sugar（PBG）, glycosylated hemoglobin （HbAlc）, body fat percentage （BF%）, waist-to-hip ratio （WHR）, maximum isometric strength of quadriceps femoris, hamstring, tibialis anterior and gastrocnemius were observed. [Results] In Baduanjin group, FBG, PBG and HbAlc decreased respectively after 12 weeks （P〈0.05）;BF% declined in female people （P〈0.05）, and between two groups, it was also showed significant differences. Compared with the same group, muscle strength increased in average as follows, quadriceps femoris 6.7 kg （19.8%）, tibialis anterior 6.5 kg （24.3%）and gastrocnemius 6.0 kg（24.7%） （P〈0.05）, compared with control group, increased significantly （P〈0.05）. [Conclusion] The 12 weeks regular Baduanjin exercise can improve the level of blood glucose control, body composition and muscle strength among the people with type 2 diabetes. It could provide the basis of traditional exercise preventing and combating diabetes and its complications.
