OBJECTIVE: This study aimed to develop a web-based exercise program based on a preliminary survey and to evaluate its effect for promotion of exercise among chronic patients.

METHODS: For the preliminary survey, an investigation of internet use among chronic patients and a review of existing 20 exercise-related web-sites were undertaken. The web-site was developed and evaluated by user satisfaction with the site and expert validity. To evaluate the effect of the site, exercise stage and commitment to a plan for exercise were compared before and after using the site.

RESULTS: The content of the web-site included exercise and health, exercise prescription, chronic disease and exercise, and my page. The users rated 3.89 for system, 3.81 for content, and 3.60 for design in the satisfaction with the site. Experts rated 4.62 for feedback and privacy, 4.31 for purpose, 4.23 for authorship, 3.76 for content, 3.71 for design, 3.62 for functionality in the evaluation of the site. The commitment to a plan for exercise after using the site was significantly higher than that before using it.

CONCLUSION: This site can be facilitated to enhance physical activity for chronic patients and further effort to continuously use and revise the site is recommended.
