Popis: BACKGROUND: Bioimpedance skeletal muscle indices (SMI) are used as a surrogate for skeletal muscle mass, but their associations with physical functioning and obesity need further evaluation. AIMS: To compare the associations of body mass index (BMI), bioimpedance spectroscopy-based calf intracellular resistance (Cri-SMI), and single-frequency bioimpedance analysis (SF-SMI) indices with physical performance and the functioning of community-dwelling older people at risk of or already suffering from sarcopenia. METHODS: Pre-intervention measurements of the screened subjects and the participants of the Porvoo sarcopenia trial (N = 428) were taken. Cri-SMI, whole-body SF-SMI, and BMI were related to hand-grip strength, walking speed, short physical performance battery (SPPB), and the physical component of the RAND-36. RESULTS: Among the older people (aged 75-96), Cri-SMI correlated inversely with age (men r = - 0.113, p
