The participants were classified into four groups: robust; low muscle mass only; low grip strength and\/or physical function only; and low muscle mass with low grip strength and\/or low physical function (sarcopenia) based on the Asian Working Group for Sarcopenia 2019 definition. Muscle mass was assessed using dual\u2010energy X\u2010ray absorptiometry and a bioelectrical impedance analysis.
