抗阻运动对糖尿病前期患者作用效果的研究

Effect of resistance exercise in prediabetic patients

目的探讨抗阻运动对糖尿病前期患者代谢指标、胰岛素抵抗及疾病转归的作用效果。方法选择2014年7~11月该院周围小区尤其是离退休老人中糖尿病前期患者80例,按照随机数字表法将其分成对照组40例(完成数据分析39例,失访1例),观察组40例(完成数据分析34例,失访6例),对照组予饮食教育,电话随访,每周1次,连续6个月;观察组在饮食教育基础上进行抗阻运动,每周3次,每次40 min,连续6个月,分析两组患者代谢指标、胰岛素抵抗及疾病转归的影响。结果观察组34例糖尿病前期患者空腹血糖、胰岛素抵抗优于对照组,差异均有统计学意义(P<0.05);观察组患者转变为糖尿病的比例为20.59%,对照组转变为糖尿病的比例为46.15%,两组比较,差异有统计学意义(P<0.05)。结论抗阻运动可以有效降低空腹血糖,改善患者的胰岛素抵抗,提高胰岛素敏感性,预防糖尿病的发生。

Objective To evaluate the effect of resistance exercise on metabolic indexes ,insulin resistance and prognosis in prediabetic patients. Methods Eighty retired prediabetic patients in residential areas around the hospital were selected from July to November 2014, and divided into the control group （with 39 cases finished the data analysis and 1 case was lost during the follow-up） and the observation group （with 34 cases finished the data analysis and 6 cases were lost during the follow-up） by random number table, 40 cases in each group. The control group was with diet education and telephone follow-up, once a week for 6 months ,while the observation group was added with resistance exercise on the basis of diet education,three times a week for 6 months, 40 minutes every time. The metabolic indexes, insulin resistance and prognosis in the two groups were analyzed and compared. Results The fasting blood-glucose （FPG） and insulin resistance of 34 prediabetic patients in the observation group were superior to that in the control group, with statistically significant difference （P〈0.05）. The incidence of diabetes is 20.59% in the observation group ,which was lower than 46.15% in the control group, and the difference had statistical significance （P〈0.05）. Conclusion Resistance exercise can reduce the level of FPG,improve insulin resistance,increase insulin sensitivity and prevent the incidence of diabetes.
