Exploring the Effectiveness to Web-based Exercise Among Community-dwelling Adults With High Body Fat

The study findings can derive an effective exercise type either web-based or supervise exercise as well as build a series of exercise video that can promote self-exercise at home for health promotion for community residents.

Background: Web-based exercise is effective alternative training for community residents on health improvement; however, adherence to their performance is challenging. Purpose: This study aimed to (1) compare the effectiveness of 16-week exercise on improving blood samples, body composition, and anthropometric parameters between web-based exercise and supervised exercise; and (2) examine the trajectory of exercise adherence of web-based exercise for attendance and intensity over time for community-dwelling adults with high body fat. Design: A two-arm randomized control trial. Method: Participants who received 16-week supervised exercise for aerobic exercise training on 2020 in our previous project was served as one of control groups (n = 34). In present project, purposive sampling will be used to enroll a target of 66 community-dwelling residents aged 40-64 years with inactive habits and body fat percentage ≧ of 25% for males and ≧ 30% for females in study. Eligible participants will be stratified by sex and then block randomly divided into web-based exercise or a control group (without any exercise intervention). The web-based exercise will prescribe a 30-minute of aerobic exercise at least moderate intensity prescription for three times per week. Heart rate reserve and self-perceived exertion will be self-recorded on the web by participants. Generalized estimating equations will be used to explore the effectiveness of web-based exercise. Implications: The study findings can derive an effective exercise type either web-based or supervise exercise as well as build a series of exercise video that can promote self-exercise at home for health promotion for community residents.
