At baseline, the OKG showed lower functional performance and unilateral balance, and impaired
lower-limb loading distribution compared to the OG and the YG (p,0.05). After resistance training, the OKG
showed improvements in functional performance (,13% in sit-to-stand and rising from the floor, ,16% in
stair-climbing and ,23% in 6-minute walking (6 MW)), unilateral balance (,72% and ,78% in TKA and OA
leg, respectively) and lower-limb loading distribution, which were greater than those observed in the OG and
the YG. The OKG showed post-training 6 MW performance similar to that of the OG at baseline. Sit-to-stand
performance and unilateral stand balance were further restored to post-training levels of the OG and to
baseline levels of the YG.
