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

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.
