臺北市某高中男生從事規律運動意圖和行為之研究

The purpose of the study is twofold: to predict and explain the male students' intention and behavior regarding regular exercise by means of Ajzen's theory of Planned Behavior (TPB), and to compare TPB with the Theory of Reasoned Action (TRA) to find out which theory is more feasible in explaining the adoption of regular exercise behavior. The Ajzen & Fishbein type of questionnaire was chosen and administered to 456 high school male students. Information about student's actual regular exercise behavior was gathered through telephone interviews two months after the survey questionnaire was conducted. The results indicated that the hypothesis of the TPB was highly supported. Students' intentions were significantly related to their actual regular exercise behavior. Multiple regression analysis provided that attitudes, subjective norms and perceived behavioral control accounted for 55% of variance in the intention to exercise regularly suggesting that perception of control has an important impact on a student's behavioral motivation Among students who did not exercise regularly, there were significant differences in behavior beliefs, normative beliefs and control beliefs, as compared with those who did. This study supported the hypothesis that the TPB was more successful than TRA in predicting behavior concerning regular exercise.
