Abstract Objective  The aim of the present study was to associate phase angle (PhA) with sarcopenia and its components in physically active older women. Methods  A cross-sectional study was performed with 94 physically active older women. PhA and muscle mass were assessed by bioelectrical impedance. Muscle strength was measured by handgrip strength (HGS) and functional capacity was evaluated by 4-meter walk test. Sarcopenia was diagnosed according to the European Consensus on Definition and Diagnosis of Sarcopenia (2010). Participants were evaluated according to the PhA tercile. The individuals were divided into two groups: 1st vs. 2nd and 3rd terciles. The individuals in the first tercile were considered having low PhA (
