摘要:Statewide Extension walking programs are making an effort to increase physical activity levels in America. An investigation of all 20 of these programs revealed that 14 use websites as marketing and educational tools, which could prove useful as the popularity of Internet communities continues to grow. Website usability information and an analysis of all 14 sites were combined to determine characteristics that may enhance the efficacy of these sites. Application of these findings could allow Extension professionals to more efficiently communicate with the public about exercise, nutrition, and state walking programs.
