本研究之目的在探討影響成年人運動行為的因素，以南部某學院夜間上課及某大學之學習指導中心之全體學生為研究對象，實際參與的樣本為400人。資料之收集主要採自填式問卷，統計方法主要有階層才是迴歸及徑路分析等。研究結果發現在最近三個月沒有運動的百分比約有35%，而平均每週運動1.5小時以上者約有29%。階層複迴歸分析結果發現性別、年齡、社會支持及知覺變項對運動行為的解釋共達15%的變異量。經徑路分析之後，顯示影響成年人運動行為的主要因素，有性別、社會支持、知覺健康狀況及知覺自我效能，其徑路係數介於0.10-0.19之間。

The purpose of this study was to explore the determinants of exercise behavior in adults. A total of 400 adults completed self-report questionnaires. The questionnaires included a demographic data sheet, past 3- month exercise questionnaire, interpersonal influences scale, self-rated health sub-index, self-rated abilities for health practice exercise subscales, and exercise benefitslbarriers scale. Results showed that 35.3% report-ed that they never performed any type of exercise; and only 29.0% practiced more than 90 minutes each week in the past 3 months. The resuits indicated that all of the variables predicted 15% of the variance in exercise behavior. Of all the variables, sex, interpersonal influences, perceived health status, and perceived exercise self-efficacy made significant contributions to the prediction of exercise behavior. Path coefficients ranged from 0.10 to 0.19.
