Summary: | 碩士 === 國立中正大學 === 運動與休閒教育研究所 === 99 === Based on the framework of Theory of Planned Behavior (TPB), this study investigates mountain biking behavior among the participants of mountain biking. Among the mountain roads in central Taiwan, Questionnaires were distributed by the method of convenience sampling. 241 questionnaires were considered valid, and were statistically analyzed by descriptive statistics, product-moment correlation, regression analysis, and hierarchical multiple regression. The result shows that the percentage of male participants is 94.5%. The average age is 38, and the average experience of biking is 46.7 months. 58.5% of the participants are married, and 58.5% are college graduates. 32.2% of the bikers spend over 50,000 NT to purchase their bicycle. The attitude, subjective norm, and perceived behavioral control of mountain biking are significantly positively related to the constructive beliefs. Subjective norm is found the most dominant, followed by attitude and perceived behavioral control. The TPB model is found significant by regression analysis, which interprets the variance of 27.8% of behavioral intention. In terms of the predictions on attitude, subjective norm, and perceived behavioral control over behavioral intention, perceived behavioral control is better than attitude. Subjective norm does not reach the level of significance. In terms of predicting mountain biking behavioral intentions, TPB model shows better results than Theory of Reasoned Action (TRA).
