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 .
The effects of high- and moderate-resistance training on muscle function in the elderly.
The purpose of this study was to investigate the effects of a 12-week resistance-training program on muscle strength and mass in older adults . Thirty-three inactive participants ( 60 - 74 years old ) were assigned to 1 of 3 groups : high-resistance training ( HT ) , moderate-resistance training ( MT ) , and control . After the training period , both HT and MT significantly increased 1-RM body strength , the peak torque of knee extensors and flexors , and the midthigh cross-sectional area of the total muscle . In addition , both HT and MT significantly decreased the abdominal circumference . HT was more effective in increasing 1-RM strength , muscle mass , and peak knee-flexor torque than was MT . These data suggest that muscle strength and mass can be improved in the elderly with both high- and moderate-intensity resistance training , but high-resistance training can lead to greater strength gains and hypertrophy than can moderate-resistance training
