本研究目的旨在探討自行車活動參與者參與動機、參與阻礙與再參與意願之關係。本研究針對曾經參與自行車活動之參與者對象，以立意抽樣方法，發放問卷400份，回收有效問卷387份，並將回收資料透過SPSS for Windows18.0以描述性統計、多元迴歸等統計方法，進行資料處理分析。研究結果發現：（一）場所服務阻礙為參與者遭遇之最大阻礙；（二）參與動機對再參與意願的預測力最高。場所服務阻礙為自行車活動參與者經常面臨較大的阻礙，建議未來相關單位應進一步提升運動指導員的質與量，藉此降低此方面的阻礙，並有效提升參與者「繼續參加類似活動」意願。

The purpose of this study was to investigate the relationships among motivations, constraints and intent to repeat participation in participants of cycling event. A questionnaire survey was administered. A total of 400 questionnaires were distributed, of which 387 were valid. The data were analyzed by descriptive and multiple regression analyses using SPSS 18.0. Conclusions were as follows: (a) Service constraint was the major constraint encountered by the cycling participants; (b) Motivation could significantly predict willingness to participate again. Service constraint was the major constraints encountered by the cycling participant; therefore, it is suggested that the authorities concerned should enhance the overall quantities and qualities related to sport instructors. In this way, the service constraints could be reduced and thus promote the participants' intent to repeat participation.
