BCW-Based Resistance Training for Community-Dwelling Sarcopenia Patients

The purpose of this randomized controlled trial is to evaluate the effects of a Behavior Change Wheel (BCW)-based resistance exercise program on muscle health, physical performance, and exercise adherence in community-dwelling older adults with sarcopenia. Participants will be randomly assigned to either an experimental group or a waitlist control group. The experimental group will receive a 12-week BCW-based resistance exercise intervention (twice a week) immediately. The waitlist control group will maintain their usual routine for the first 3 months for comparison, and will then cross over to receive the identical 12-week intervention. The study aims to provide an effective and ethical exercise management strategy for sarcopenic patients.
