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 .
Effect of exercise training on peak aerobic power, left ventricular morphology, and muscle strength in healthy older women.
The effect that aerobic ( AT ) and /or strength training ( ST ) has on altering peak aerobic power ( VO2peak ) , muscle strength , left ventricular ( LV ) morphology , and diastolic filling in healthy older women is not known . We assessed the effects of 12 weeks of AT , ST , combined aerobic and strength training ( COMT ) , or no training ( NT ) on VO2peak , muscle strength , LV morphology , and diastolic filling in 31 healthy women ( 68 + /- 4 years ) .  Relative VO2peak was significantly greater after 12 weeks of AT , ST , or COMT . Upper and lower extremity strength were significantly higher after 12 weeks of ST or COMT with no change after AT or NT . LV morphology and diastolic filling were not altered after 12 weeks of AT , ST , COMT , or NT . Twelve weeks of ST or COMT are as effective as 12 weeks of AT for increasing relative VO2peak , however , ST and COMT are more effective than AT for improving overall muscle strength
