彈力帶低阻力訓練對第二型糖尿病病患功能性體適能、血糖及血脂之影響

Effects of Low Resistance Training with the Use of Elastic Band on Functional Fitness, Glucose and Lipid in Type 2 Diabetes

目的：探討使用低強度阻力彈力帶訓練對第2型糖尿病病患功能性體適能、血糖及血脂之影響。方法：採類實驗性（quasi-experimental design）研究設計，40位受試者，實驗組接受一位專業健身教練指導每週2次，每次一小時，持續12週的團體彈力帶訓練（n=17），對照組依平日活動方式未給予任何介入（n=23）。結果：在體適能的改變方面，除握力外，實驗組可顯著改善柔軟度、下半身肌力、肌耐力、敏捷性與動態平衡，且兩組間呈顯著差異（p＜0.05）；實驗組也能顯著降低身體質量指數（p=0.002）及胰島素抗性（p=0.01），兩組間亦有顯著差異。事後檢定干擾變項，兩組間的飲食攝取與藥物使用則無顯著的差異（p＞0.05）。結論：短期低阻力彈力帶訓練可改善本研究之第2型糖尿病病患功能性體適能、身體質量指數及胰島素抗性。

Objectives. To investigate the effects of low-intensity elastic resistance training on the functional fitness, blood glucose level, and blood lipid levels of patients with type 2 diabetes. Methods. A quasi-experimental design was used, and 40 patients were recruited. Patients in an elastic resistance training group were instructed by a professional fitness trainer twice a week for one hour each over twelve weeks (n=17). The control group (n=23) received no training interventions. Results. With regard to functional fitness, except for grip strength, the patients in the experimental group showed significant improvements in flexibility, lower limb muscle strength, muscle endurance, agility, and dynamic balance over the control group (all p＜0.05). The experimental group also showed significant decreases in body mass index (BMI) and insulin resistance (p = 0.002, p = 0.01, respectively). A post hoc analysis found that dietary intake and medication use did not differ between the two groups (p＞0.05). Conclusion. Short-term low-intensity elastic resistance training can improve the functional fitness, BMI, and insulin resistance of patients with type 2 diabetes.
