Participation in regular physical activity (PA) is critical to sustaining good health. While a few attempts have been made to use internet-based interventions to promote PA, no system review has been conducted in determining the effectiveness of the intervention. The purpose of this study was to conduct a review under the framework of persuasive technology (PT). Based on a comprehensive of literature search, nice experimental studies were identified and evaluated using the PT functional triad defined by Fogg in 2003. It was found that only two studies led to short-term impact in promoting PA and, furthermore, two studies have found that the intervention based traditional print materials worked better. From a perspective of PT, none of the studies designed its intervention based on the framework of captology and few took full advantages of PT functions. Designing new-generation, PT based internet intervention and examining related human factors are urgently needed.
