The decline of muscle strength is associated with physical disability in
late adulthood. Progressive resistance strength training has been demonstrated to
be an effective intervention to increase muscle strength, however, its effect on
reducing physical disability in older adults is unclear.
The purpose of this
study is to examine the effect of progressive resistance strength training on
physical disability via meta-analysis. METHOD: Two reviewers independently
searched for qualified trials, assessed trial quality and extracted data. Trial
inclusion criteria are: (1) Randomised controlled trials, (2) Mean age of
participant sample is >/= 60 years, (3) Progressive resistance strength training
as the primary intervention and (4) the trial included outcome measures of
physical disability (i.e. physical function domain of the Short-Form 36).
RESULTS: Thirty-three trials were analysed. Although the effect size is small,
the intervention groups showed reduced physical disability when compared to the
control groups (SMD = 0.14, 95% CI = 0.05 to 0.22). CONCLUSIONS: Progressive
resistance strength training appears to be an effective intervention to reduce
physical disability in older adults. To maximise the effect, we suggest
therapists use responsive outcome measures and multi-component intervention
approach.
