SARC-F is a five-question self-reported questionnaire to screen for sarcopenia risk. The question comprises the subjects’ perception of his/ her limitations in strength, walking ability, rising from a chair, stair climbing, and experiences with falls [21]. ALM; appendicular lean mass. ASM; appendicular skeletal muscle mass. SPPB; Short physical performance battery. TUG; Timed-Up and Go test. SMI; Skeletal muscle index (total skeletal muscle mass (kg)/height (m)2). VFA; Visceral fat area.
