Relationships between Regional Muscle Mass Measured Using a Household Body Composition Meter and Center of Pressure Sway and the Functional Reach Test in Healthy Adult Men

Abstract

[Purpose] The purpose of this study was to examine the relationships between muscle mass, measured using a household body composition meter, by region and center of pressure (COP) sway in stabilometry and Functional Reach Test (FRT). [Participants and Methods] Forty healthy adult males were enrolled. The COP sway index was measured using a stabilometer while the subjects were standing still. The FRT was performed as a dynamic balance evaluation. Using a household body composition meter, the muscle masses of the whole body, left and right upper limbs, trunk, and left and right lower limbs were measured. [Results] There was no significant correlation between any of the muscle masses and the COP sway index; however, there was a significant moderate positive correlation between trunk muscle mass and FRT. [Conclusion] A relationship between trunk muscle mass and FRT was found; therefore, the use of a household body composition meter may be clinically meaningful.
