Serious adverse events were rare , and no serious events were reported to be directly related to the exercise programme .
This review provides evidence that PRT is an effective intervention for improving physical functioning in  older people , including improving strength and the performance of some simple and complex activities .
BACKGROUND Muscle weakness in old age is associated with physical function decline .
Progressive resistance strength training ( PRT ) exercises are design ed to increase strength .
OBJECTIVES To assess the effects of PRT on older people and identify adverse events .
Resistive training and long-term function in older adults.
The purpose of this study was to evaluate the effects of a 24-month moderate-intensity resistive-training intervention on strength and function in older adults .  A repeated- measures experimental research design was employed as a sample of 55 apparently healthy , older , community-dwelling volunteers ( 30 exercisers- 25 women and 5 men ; 25 comparisons- 16 women and 9 men ) were evaluated for strength of 5 muscle groups that influence lower extremity movement and physical function . Strength and function were evaluated at 6-month intervals . The findings from this study indicate that a moderate-intensity resistive-training program increases strength in older adults and that the strength benefits are retained for the duration of the intervention . Furthermore , a long-term strength-training program can increase independent-function skills in older adults and might therefore aid in prolonging functional independence
