十二週健走運動與飲食控制計畫對停經婦女身體組成及血脂肪的影響

The Effects of Twelve-Week Walking and Diet Program on Body Composition and Blood Lipid in Postmenopause Women

本研究目的在探討體重過重停經婦女，施以十二週不同的體重控制健走運動與飲食控制計畫後，是否會影響體重（body weight）、身體組成（BMI）及體內之總膽固醇（TC）、高密度脂蛋白（HDL）、低密度脂蛋白（LDL）、三酸甘油脂（TG）和總膽固醇與高密度脂蛋白的比值（TC／HDL）。以28位平均55.2±2.16歲體重過重（BMI＞30）之停經婦女為對象，依自願分為四組：（1）健走運動與飲食控制組6位、（2）健走運動控制組7位、（3）飲食控制組8位及（4）對照組7位。健走運動以每週運動三次，每次30分鐘，心跳維持在個人最大心跳率的65％～85％間，並以無線心跳記錄錶（POLAR）監測。飲食控制則要求受試者每天減少500～1000大卡之熱量攝取。所得資料以t檢定考驗各組前、後測的差異情形，並以單因子變異數分析（One-Way ANOVA）考驗四組前測的同質性，及四組後測之body weight、BMI、TC、HDL、LDL、TG與TC／HDL值是否有差異，如達顯著水準，再以薛費法（Scheffe method）進行事後比較，顯著水準訂為P＜.05。結果發現，施以單一的健走運動或飲食控制，對於降低body weight、BMI、TC、LDL、TG和TC／HDL在數值上有明顯下降；在HDL方面則明顯上升，而同時施以健走運動和飲食控制則效果最好。The objective of this study was to discuss whether postmenopausal women's weight, body composition (BMI) and total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), triglyceride (TG) and TC/HDL of the body would change after undergoing a twelve-week weight control plan of walking and diet. Twenty eight postmenopausal women, who were more than 55.2±2.16 years old on average and overweight (BMI>30), were divided themselves voluntarily into 4 groups:(1) six in the walking-and-diet control group, (2) seven in the walking control group, (3) eight in the diet control group, and (4) seven in the control group. Participants walked thirty minutes at a time, 3 times a week, and were monitored by a POLAR heart rate monitor. The heart rate range during training was kept at 65%-85%. The participants were asked to carry out diet control by reducing 500~1000 calories daily. The data was analyzed by t-test and one-way ANOVA; comparing the results with the Scheffe method then continued the analysis. The statistical significance was determined at the P< .05. The results show that either diet-control or the walking-control groups obviously increase the HDL and decrease the weight, BMI, TC, LDL, TG and TC/HDL. The diet-and-walking control group reaches the best result.
