It is also possible that PRT alone is not a robust intervention for balance control .
This is the first systematic synthesis of the literature to examine the effectiveness of PRT alone on balance performance in older adults .
The limited evidence presented in currently published data has not consistently shown that the use of PRT in isolation improves balance in this population .
The serious health , social and economic consequences of falls are well documented .
Lower extremity muscle weakness and power as well as balance impairment are major independent intrinsic contributors to falls and amenable to intervention .
Progressive resistance training ( PRT ) is widely accepted as an appropriate modality for treating sarcopenia and has been reported to improve balance .
However , other studies affirm no significant effect of PRT on balance .
To date , there is no clear , definitive statement or synthesis of studies that has examined the effect of PRT on balance .
Therefore , our objective was to systematic ally review the literature to probe the merit of PRT as a single intervention on balance performance in older adults .
Exercise effect on dynamic stability in older women: a randomized controlled trial.
OBJECTIVE To determine whether a 12-month program of regular exercise can improve dynamic postural stability in older women . DESIGN R and omized controlled trial of 12 months ' duration . SETTING Conducted as part of the R and wick Falls and Fractures Study , in Sydney , Australia . PARTICIPANTS One hundred and twelve community-dwelling women aged 60 to 85 years ( mean age 71.2 , SD = 5.4 ) . OUTCOME MEASURES Quantitative measures of dynamic postural stability : maximal balance range and coordinated stability . MAIN RESULTS Exercise and control subjects were tested before , midway through , and at the end of the trial . The stability measures had good test-retest reliability , and test performances were significantly associated with measures of lower limb muscle strength , reaction time , neuromuscular control , and body sway . At initial testing , exercisers and controls performed similarly in the two stability measures . The mean number of classes attended for the 48  exercise subjects who completed the program was 58.4 ( range 26 - 77 ) . At the end of the trial , the exercise subjects showed significantly improved performance in both the maximal balance range and coordinated stability tests , with no improvement evident in the controls . Improvements in coordinated stability were associated with corresponding improvements in ankle dorsiflexion , hip extension , and hip flexion strength . CONCLUSION These findings show that exercise can significantly improve dynamic postural stability in older persons and eluci date some possible mechanisms by which such improvements may be mediated
