This study, based on hierarchial model of leisure constraints, aimed to investigate the influence of constraints dimensions on leisure and sports participation. The data were collected via a self-administrated residents questionnaire survey in mid-sized city in Korea. Descriptive and inferential analyses including factor analysis, one-way and multivariate analysis of variances were used to analyze the data.. The results showed that the constraint dimensions offered a significant contribution towards the prediction of participants and non-participants. The individual and psychological lack of interest, lack of knowledge and skill, and time dimensions were the best predictors for distinguishing between participations and non-participations.
