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 aerobic and resistance training on fractionated reaction time and speed of movement.
To evaluate the effect of aerobic and variable resistance exercise training on fractionated reaction time ( RT ) and speed of movement ( SM ) in elderly individuals , premotor time ( PMT ) , motor time ( MT ) , total RT , and SM were measured in 49 healthy , untrained men and women , 70 to 79 years of age , before and after 6 months of training . Subjects were r and omized into either a walk/jog ( n = 17 ) , a strength training ( n = 20 ) , or a control group ( n = 12 ) . Improvements in aerobic capacity were only weakly related to reduced total RT ( r = 0.30 , p less than .05 ) . Analysis of covariance revealed that there were no differences ( p greater than .05 ) among the three groups after training with respect to PMT , MT , total RT , and SM . These findings indicate that 6 months of aerobic and strength training did not induce significant changes in RT or SM in this group
