Abstract

What are the main findings?• A seated bioelectrical impedance sensor accurately estimated appendicular muscle mass against DXA in older adults. • The Sergi prediction equation provided higher agreement and lower estimation error than the Kyle equation.

What are the implications of the main findings?

• Seated bioelectrical impedance enables rapid, practical muscle mass assessment without compromising measurement validity. • The phase angle derived from the sensor provides complementary information on muscle function and sarcopenia.
