BMI, body mass index; BC, brachial circumference; FC, femoral circumference. BC is the brachial circumference of dominant arm. The mean FC is the mean circumference of both femurs. A larger FC indicates a larger circumference for both femurs. A smaller FC indicates a smaller circumference for both femurs. The grip strength represents the grip strength of the dominant arm. Correlation coefficient: the r and P values were obtained by Pearson product moment correlation.

^*P < 0.05,
