Poor functional performance levels have been associated
with increasing rates of disability and daily living dependence
(36,37), as well as a higher risk for mortality and
nursing home admission (38). For example, older subjects
aged 70 to 79 years with the 5-repetition sit-to-stand time
above 12.6 s can be considered to have a lower-than-average
performance (39). Older subjects aged 65 to 99 years
performing the 5-repetition sit-to-stand test above 13.5
seconds displayed a greater risk (20% to 420%) of having
mobility-related disability after 2 years of follow-up (37).
Although both the OKG and OG showed baseline sit-tostand
performance below the above-mentioned cut-off
points, the resistance training-induced improvements in
functional performance of both the OKG and OG observed
in the present study may have important clinical implications
by helping to reduce the risk of future disability and to
increase the number of years with daily living independence.
