Abstract

[Purpose] In this study, we investigated the relationship between the muscle thickness of the quadriceps measured by an ultrasound imaging system and physical function. [Subjects] The subjects were 98 community-dwelling older women aged over 60: average age, 72.7. [Methods] The muscle thickness of the quadriceps femoris at 10 cm above the upper border of the patella was evaluated by an ultrasound imaging system, and physical fitness which included knee extension strength was evaluated. [Results] There were significant correlations between muscle thickness and knee extension strength (r= .333, p< .001), hand-grip strength (r= .255, p< .05), and one-legged standing time (r= .278, p< .001). [Conclusion] The muscle thickness was correlated with physical fitness. However, multiple linear regression analysis indicated that muscle thickness did not predict the strength of knee extension precisely enough.<br>
