The Effectiveness of Smart Technology Interventions Combining Nutrition and Exercise for Older Adults at Risk of Sarcopenia

Sarcopenia, characterized by muscle loss and weakness, is a major health issue among older adults and impacts mobility and quality of life. This study addresses the current lack of long-term, technology-assisted support for managing this condition at home. This randomized controlled trial (RCT) will evaluate a 12-week smart-technology-based program for 60 older adults at risk of sarcopenia. Intervention: Participants in the intervention group will receive a technology-assisted program delivered through a Line Bot system. The platform provides personalized exercise training videos, nutrition education, daily reminders, and a point-based logging system to support adherence and monitor engagement. The control group will receive standard clinic-based care. Purpose: The study aims to examine whether the smart technology intervention can improve muscle mass, physical performance, quality of life, and self-management ability among older adults at risk of sarcopenia. Expected Benefit: The digital intervention is anticipated to offer a more effective, accessible, and sustainable approach compared with standard care, providing practical support for preventing muscle decline in community-dwelling older adults
