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 .
Strength training and hemodynamic responses to exercise.
Sixty-two older adults ( 68.4+/-6 years ) were r and omized into a control group ( n=16 ) , low-intensity exercise group ( n=22 , LEX ; 50 % 1-repetition maximum ; 13 repetitions per exercise ) , or a high-intensity exercise group ( n=24 , HEX ; 80 % 1-repetition maximum ; eight repetitions per exercise ) group . Subjects trained for 24 weeks , performing 1 set for each of 13 exercises . Subjects performed a grade d exercise test ( GXT ) at baseline and after 24 weeks of strength training .  Heart rate , systolic , and diastolic blood pressures were measured at rest , during the GXT and 1 , 3 , and 5-min post-GXT . Mean arterial pressure was also calculated . Post-training , time to peak systolic and diastolic blood pressures and heart rate was increased in the LEX and HEX groups by 22.9 % and 44.5 % , respectively ( p<0.05 ) . Diastolic blood pressure , heart rate , and mean arterial pressure during the GXT were significantly decreased ( p<0.05 ) in the HEX group following training . Post-GXT heart rate was lower in the HEX and LEX groups compared to control ( p<0.05 ) indicating a more rapid recovery . Resistance exercise prolongs the onset of peak cardiovascular responses , decreases the cardiovascular response to exertion , and improves recovery from maximal exertion
