Table 3 Correlation of knee extension muscle strength with SMI, walking speed and handgrip strength

	Knee extension muscle strength
	Men (N = 31)	Women (N = 92)
SMI	0.41 (P = 0.02)	0.10 (P = 0.33)
Walking speed	0.35 (P = 0.051)	0.17 (P = 0.092)
Handgrip strength	0.53 (P = 0.002)	0.36 (P < 0.001)
Unipedal standing test	0.61 (P < 0.001)	0.37 (P < 0.001)

SMI skeletal muscle mass index; Unipedal standing test shows unipedal standing retention time
