PRT had a large positive effect on strength ( 41 trials , 1955 participants ) , but there was statistical heterogeneity that was not explained by differences in study quality , participant characteristics or the exercise program .
REVIEW ER 'S CONCLUSIONS PRT appears to be an effective intervention to increase strength in older people and has a positive effect on some functional limitations .
However , the effect of this intervention on more substantive outcomes such as measures of disability or HRQOL remains unclear .
BACKGROUND Muscle weakness in old age , is associated with physical disability and an increased risk of falls .
Progressive resistance strength ( PRT ) training exercises ( i.e. movements performed against a specific external force that is regularly increased during training ) are design ed to increase strength in older people .
OBJECTIVES To assess the effect of PRT on measures of physical disability , functional limitation and impairment in older people  , and identify adverse events .
The effects of strength training on strength and health-related quality of life in older adult women.
The short-term effects of an accessible exercise intervention on the strength and health-related quality of life ( HRQOL ) among older adult women were evaluated . We conducted an 8-week resistance training intervention utilizing elastic b and s in 62 community-dwelling women with a mean age of 68 years . Participants were r and omly assigned to either an exercise or a control group . Pre- and postintervention assessment s included strength tests and HRQOL . Results revealed significant increases in three major muscles compared to the control group . However , there were no significant changes on either mental or physical health functioning . The elastic b and s provide older adult women with an inexpensive , practical exercise program that effectively increases strength within 8 weeks but may have little effect on self-reported HRQOL
