摘要

本研究乃鑑於目前女大學生規律運動情況不佳導致體脂過高，造成潛在健康風險，因此應用跨理論模式探討健走介入對高體脂女大學生運動行為及肥胖之改變情形。以準實驗設計，招募無規律運動行為、體脂肪大於30%之女大學生為研究對象。實驗組12名，每週進行3~5次之30~40分鐘健走運動共六週；對照組18名，不進行任何運動介入。兩組於介入前後進行檢測。結果顯示(1)實驗組於介入後，知覺運動利益及運動自我效能顯著高於介入前，知覺運動障礙顯著低於介入前；對照組無顯著差異。(2)實驗組於介入後，運動改變階段皆進入具每週三次以上規律運動之準備期及行動期；對照組前後無變化。(3)實驗組於介入後，體脂肪百分比、腰臀比顯著低於介入前，對照組則無顯著差異。本研究結果顯示健走對運動行為影響因子及肥胖改善具有正向效益，同時驗證跨理論模式之各項影響因子會隨運動改變階段不同而有所變化。研究結果可供未來針對高體脂女大學生設計運動計畫之參考。

The purpose of this study was to assess the effectiveness of Transtheoretical Model (TTM) by the intervention of brisk walking for female college students with high body fat. Thirty female students (percentage body fat＞30%) were recruited in the stage of ”precontemplation”, ”contemplation” and ”preparation”. The experiment group (n=12) received 6-weeks brisk walking intervention (30~40 min, 3~5 times per week), while the control group (n=18) didn't receive any intervention. Exercise behavior determinants such as perceived exercise benefit、perceived exercise barrier、exercise self-efficacy and obesity indicators such as percentage body fat、waist-hip-raio and body mass index were measured on baseline, 6th week, and 14th week. The results revealed that significant and positive changes on perceived exercise benefit, perceived exercise barrier, exercise self-efficacy, percentage body fat, waist-hip-raio for the experiment group on 6th week, while no significant difference in the control group. The results verified that all exercise behavior determinants of TTM were different among different stages of change. Regular exercises play an important role on weight-loss and health benefit maintenance. This result is useful as a reference for designing exercise intervention to female college students with high body fat in the future.
