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

Study Overview
=================
Brief Summary
-----------------
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.

Detailed Description
-----------------
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.

Design Details

Primary Purpose: Prevention
Allocation: Randomized
Intervention Model: Parallel Assignment
Interventional Model Description: we will design a randomized controlled trial comprising two arms of a 16-week exercise web-based aerobic exercise (AE) training and another control group without any exercise intervention.
Masking: Single


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: web-based exercise<br>Participants will receive web-based aerobic exercise (AE) training three times per week for 16 weeks. | Behavioral: web-based aerobic exercise<br>* Our designed AE program involved core muscle training through movements including marching, step touches, lunges, v-steps, box steps, twists, knee-ups, scoops, and scissors.<br>|
| No Intervention: control group<br>control group without any intervention. | |
