Effect of a Web Site Intervention on Physical Activity of College Females

This article provides a comprehensive review of Internet– and Website–based physical activity interventions targeting adult populations. Search procedures identified 72 unique Internet-based physical activity interventions published in peer-reviewed journals. Participants of the studies were predominately White, middle-aged (mean age = 43.3 years), and female (65.9%). Intervention durations ranged from 2 weeks to 13 months (median = 12 weeks). Forty-six of the studies were randomized controlled trials, 21 were randomized trials without a control condition, 2 were non–randomized controlled trials, and 3 used a single-group design. The majority of studies (n = 68) assessed outcomes immediately following the end of the intervention period, and 16 studies provided delayed postintervention assessments. Forty-four of the 72 studies (61.1%) reported significant increases in physical activity. Future directions for Internet-based physical activity interventions include increasing representation of minority and male populations in Internet-based efforts, conducting delayed postintervention follow-up assessments, and incorporating emerging technologies (ie, cellular and Smartphones) into Internet-based physical activity efforts.

“…Participants in this study highlighted goal setting, interaction with professionals, and personalization as important components of online programming. Formats such as Facebook, text messaging, and email may be effective, 52,53 but additional research is needed on ways to increase sustained engagement and long-term motivation. Findings from our study suggest mixing face-to-face with online components may provide the variability students need to keep them motivated and engaged.…”

“…This may have led to the review's lack of positive results, as it is a difficult task to maintain intervention effects long after the participants have been exposed to it. However, only three of the studies analyzed had positive outcomes that were lost at follow-up assessments, 25,32,37 so it appears as though the analysis of last measurements reported did not have a significant impact on the results. Another potential limitation is the fact that this study only examined quantitative PA outcomes that were expressed in terms of levels of activity.…”
