An internet-based intervention for promoting and maintaining physical activity: A randomized controlled trial

Abstract

Objectives: To evaluate the efficacy of a Social Cognitive Theory-based Internet intervention designed to promote and maintain leisure-time physical activity in university-aged female students in Thailand. Methods: The 3-month intervention was delivered through a website and e-mails with a follow-up evaluation 3 months after the end of the intervention. Female students (N = 220) were allocated to 4 parallel groups. Results: Significant increases in steps/day, weekly leisure-time activity score, self-efficacy, outcome expectations, and self-regulation, and reduced resting heart rate were observed at the end of the intervention. With the exception of resting heart rate, the intervention effects on these variables also remained at the follow-up. Conclusions: The Internet intervention program was effective in promoting and maintaining leisure-time physical activity in university-aged female students. © 2014, PNG Publications.
