Abstract

[Purpose] The purpose of this study was to clarify the relationship between the muscle mass and respiratory function of healthy adults. [Subjects and Methods] The subjects were 32 males and 19 females with a mean age of 19.4 ± 0.8 years. The subjects’ muscle mass was measured, and grip strength, toe-grip strength, forced vital capacity (FVC), %FVC, one-second forced expiratory volume (FEV1), and the FEV1/FVC ratio were also determined. The appendicular skeletal muscle mass index (SMI) was calculated using the measurements, and its relationships with the items of physical function were investigated. [Results] SMI of the subjects was 7.49 ± 0.62 kg/m2 for males and 6.30 ± 0.49 kg/m2 for females, and significant positive correlations between SMI and grip strength (r=0.763) and FVC (r=0.779) were found. [Conclusion] A positive correlation was found between SMI and the grip strength and FVC of healthy adults.
