One-leg standing time (OLST) has been frequently used physical performance measure; however, what muscular characteristics OLST represents remains uncertain. This cross-sectional study aimed to investigate the association between and muscle clarify possibility of using as a measure. Study participants comprised 1144 older adults aged 65 years or older. Computed tomography images provided mid-thigh skeletal area mean attenuation value. was measured for maximum 60 s. Static postural instability assessed posturography. A frequency < 20 s increased by quartiles (Q1: 33.6, Q2: 12.8, Q3: 13.6, Q4: 11.9%, P 0.001) value 32.3, 21.7, 14.3, 7.7%, 0.001).
