Physical Activity Engagement outside of College Physical Education: Application of the Transtheoretical Model.

Abstract

Objective: In this study, we examined physical activity (PA) engagement outside of college physical education (PE) classes using the Transtheoretical Model (TTM). Methods: Overall, 414 university students enrolled in PE classes voluntarily participated in this study. Participants were asked to complete a survey packet to measure 4 core constructs of TTM and their PA level performed outside of PE classes. Among the participants, 150 randomly selected students were asked to wear a triaxial accelerometer for 7 consecutive days to identify their PA level. Descriptive statistics and multivariate analyses of variance were used to determine the association between stages of motivational readiness and other strategic core constructions. Results: We categorized 77% of respondents into either the "action" stage or the "maintenance" stage for engaging in additional PA outside of the classes. Behavioral processes of change showed a graded and significant association with the stages. Both self-efficacy and decisional balance were significantly higher in students at higher stages. Conclusion: Our findings showed that most students enrolled in college PE classes had additional PA outside of the class participation. In addition, behavioral processes may be effective strategies for this specific target group to promote PA.
