自我監控與運動訓練在體重過重之健康成年人體重控制的效益

Abstract

目的：本研究目的在探討12週自我監控與運動訓練的介入對於體重控制的效益。方法：41名(31位男性和10位女性，23.55±6.0歲、169.04±9.64公分、88.04±21.17公斤)體重過重的健康成年人參與本研究，所有受試者在實驗處理前、後各接受一次身體組成(體重、BMI、體脂肪百分比、骨骼肌肉百分比、腰圍、腰臀圍比)、心肺耐力(RSVHRC)、血液生化值、血壓等檢測。所有受試者給予2小時健康促進、營養與體重控制的知識講習後，隨機分成運動+紀錄組(n=10)、運動組(n=10)、紀錄組(n=11)以及控制組(n=10)等4組，進行12週的實驗介入。運動訓練在實驗室內進行，受試者採用智慧型體重控制系統橢圓機進行每週3次的運動訓練，運動處方由橢圓機自動提供；自我監控記錄則在網站或手機應用程式紀錄每天的飲食或身體活動。第13週至第16週追蹤四組受試者的自我監控情形，第17週檢測所有受試者的身體組成和血壓。研究所得資料以獨立樣本單因子變異數分析探討實驗處理後各依變項變化量百分比的組間差異，顯著水準α為.05。結果：12週實驗後，運動+紀錄組和運動組兩組的體重、身體質量指數和腰圍顯著降低；運動+紀錄組同時顯著降低體脂肪百分比和三酸甘油酯，且顯著增加骨骼肌肉百分比。結論：從事為期12週，每週3次的智慧型體重控制橢圓機運動訓練並利用App程式紀錄，可以有效改善身體組成和三酸甘油酯。減重期間，只紀錄每天的飲食和身體活動，無法有效改善身體組成和血脂。Purpose: This study was to investigate the effects of self-monitoring and exercise training on weight management after 12 weeks of behavior intervention. Methods: forty-one apparent healthy overweight adults (31 males and 10 females, 23.55 ± 6.0 years, 169.04 ± 9.64 cm, 88.04 ± 21.17 kg) were recruited to participate the study. All subjects were given a health promotion seminar on nutrition and weight management followed by being randomly assigned into exercise training combined record group(n=10), exercise training-only group(n=10), record group-only (n=11), and control group(n=10). Physiological parameters such as body composition, cardiopulmonary capacity (RSVHRC), blood biochemical markers. and blood pressure were measured before and after intervention. Toke ellipical aerobic exericse characterized by incorperating intellgent weight management system that automatically set up exercise intensity and duration according to gender, age, and weight of participant was carried out 3 times per week in exercise combined record group. For self-monitoring groups, dietary and physical activity record were obtained by self website or mobile app logging, and intervention was extended to for another 4 weeks after 12th week in these groups. Then 17 th week, body composition and blood pressure were measured in these four groups. One-way ANOVA was performed to compare the differences between the groups on percentage of change before and after intervention. The significance was set at α=.05. Results: After 12 weeks of intervention, body weight, body mass index, and waist circumference was significantly reduced on exercise training combined record group and exercise training-only group. Moreover, percentage of body fat and skeletal muscle as well as blood triglycerides were also significantly improved in exercise training combined record group. Conclusions: Elliptical exercise training incorporated with intelligent weight management system combined dietary and physical activity record could improve body composition and blood triglycerides, whereas record-only group did not appear to effectively improve body composition and blood lipids.
