the effects of resistance training in older subjects with TKA
and symptomatic OA in the contralateral knee.
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.
Increased understanding of the effects of resistance
training on the above-mentioned muscle strength-related
impairments in subjects with TKA and symptomatic OA in
the contralateral knee may help design future therapeutic
programs to reduce functional limitations and improve
quality of life in this population. Thus, the purpose of the
present study was to analyze the effects of a resistance
training program on functional capacity, lower-limb loading
distribution and balance in older women with TKA and
symptomatic OA in the contralateral knee and to compare
this group with older and young women without musculoskeletal
diseases who performed the same resistance
exercise program.
