Previously reported data from this study showed that 13
weeks of a twice-weekly resistance training program
partially restored muscle strength in older women with
TKA and symptomatic OA in the contralateral knee (16). In
this study, the women with TKA and symptomatic OA in
the contralateral knee displayed a relative muscle strength
increase and resistance exercise intensity progression
greater than those of young and older healthy women
following the same exercise training program (16). To the
best of our knowledge, there is no study analyzing the
effects of resistance training on several muscle strengthrelated
impairments commonly found in this population,
including functional performance, lower-limb loading distribution
and balance.
