Comparison of knee joint peak torque and body composition of participants between the KOA and CON groups (mean ± SD).

Body Composition/Peak Torque	KOA Group (n = 25)	CON Group (n = 22)
Muscle mass
TMM (%)	59.36 ± 3.94 *	63.24 ± 4.50
LMM (%)	18.47 ± 1.49 *	19.96 ± 1.51
Fat mass
TFM (%)	35.65 ± 4.18	33.00 ± 6.93
LFM (%)	9.29 ± 1.87	9.43 ± 2.03
Extension
aPT (Nm)	56.61 ± 14.69 *	66.02 ± 10.57
rPT (Nm/kg)	0.89 ± 0.26 *	1.11 ± 0.19
Flexion
aPT (Nm)	35.01 ± 7.96	36.43 ± 7.00
rPT (Nm/kg)	0.54 ± 0.16 *	0.62 ± 0.15
H/Q	0.62 ± 0.15 *	0.55 ± 0.08

Note: KOA group is knee osteoarthritis group, CON group is control group, TMM is total muscle mass, LMM is lower limbs muscle mass, TFM is total fat mass, LFM is lower limbs fat mass, aPT is absolute peak torque, rPT is relative peak torque, and H/Q is the relative peak torque ratio of knee flexion and extension. * p < 0.05.
