This study aims to explore influence factors related to participating intentions of windsurfers. A structural questionnaire was developed as a survey tool. The subjects of this study comprise practitioners of the windsurfing sport. A cause-effect 'recreational experiences-satisfaction-participating intention' model was constructed on the basis of the 'belief (perception)-attitude-intention' process in cognitive psychology. The two variables participation motivation (driving force of behavior) and leisure constraints (barriers of behavior) were taken as antecedents in our cause-effect model, and their relationships were subjected to testing using the structural equation modeling (SEM). The findings of this study indicate that the structural model employed fits the data very well: participating motivation exert positive effects on recreational experiences and participating intentions. In turn, recreational experiences also exert positive effects on satisfaction, and satisfaction on participating intention. Additionally, our results demonstrate that while leisure constraints produced no significant effects on recreational experiences, they do show significant negative effects on future participating intentions. All in all, participating motivation turns out to be a key driving force of participating intentions. Our research results are hoped to serve as a useful reference and guide to promotional strategies for the windsurfing sport.
