Sarcopenia is a geriatric syndrome characterized by a decline in muscle mass and strength, commonly occurring among the elderly and associated with an increased risk of falls, disability, and reduced quality of life. Factors influencing the development of sarcopenia include low levels of physical activity and high body fat percentage. Therefore, this study aimed to analyze the relationship between physical activity and body fat percentage with probable sarcopenia indicators among older adults in the working area of Sungai Selan Health Center. This research employed a cross-sectional design with consecutive sampling of participants aged over 50 years. Data were collected using the SARC-F questionnaire to assess sarcopenia, the IPAQ Short Form to measure physical activity, and Bioelectrical Impedance Analysis (BIA) to determine body fat percentage. The data were analyzed using SPSS through bivariate correlation tests. The results showed a significant relationship between physical activity level and body fat percentage, with probable sarcopenia indicators among the elderly in the working area of Sungai Selan Health Center.
