PRT results in improvements to muscle strength and some aspects of functional limitation , such as gait speed , in older adults .
However , based on current data , the effect of PRT on physical disability remains unclear .
Further , due to the poor reporting of adverse events in trials , it is difficult to evaluate the risks associated with PRT
BACKGROUND The aim of this systematic review was to quantify the effectiveness of progressive resistance strength training ( PRT ) to reduce  physical disability in older people .
Self-paced resistance training and walking exercise in community-dwelling older adults: effects on neuromotor performance.
BACKGROUND Resistance-training intervention studies have demonstrated meaningful health benefits in older adults ; however , most have used exercises performed at specific intensities on expensive equipment , which limit their widespread applicability . We tested whether two self-paced , less expensive exercise protocol s could be effective and safe for modifying neuromotor performance and functional capacity in community-dwelling adults 65 - 95 years of age . METHODS One hundred and thirty-one subjects were r and omized to a  novel resistance training , walking , or control group .  Subjects determined their level of resistance or walking intensity ( self-paced ) on a session-by-session basis . Muscle strength , balance , reaction time , stair climbing speed , and a timed pen pickup task were measured before and after the intervention period . Exercisers met three times per week for 10 months . RESULTS Significant improvements in t and em stance and single-legged stance with eyes open times and stair climbing speed were seen in both exercise groups . In addition , resistance trainers improved their muscle strength and ability to pick up an object from the floor and reduced the number of missteps taken during t and em walking , and walkers reduced t and em walking time . Controls showed no significant improvement in any variable . CONCLUSIONS The two self-paced exercise protocol s were effective at improving neuromotor performance and functional capacity in the study sample and show promise as a safe , effective , cost-efficient , acceptable exercise model for primary and secondary prevention in the general population of community-dwelling older adults
