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 .
Effects of high-intensity strength training on quality-of-life parameters in cardiac rehabilitation patients.
Cardiac rehabilitation programs have not consistently been shown to improve the psychological well being of their patients . In our study of 38 cardiac patients ( 29 men and 9 women ) , a variety of quality -of-life parameters were assessed before and after they completed either 12 weeks of high-intensity strength training or flexibility training added to their outpatient cardiac rehabilitation  aerobic exercise program . The strength-trained patients increased their self-efficacy scores for lifting ( 29 % vs 4 % , p < 0.05 ) , push-ups ( 65 % vs. 17 % , p < 0.01 ) , climbing ( 36 % vs 0 % , p < 0.001 ) , and jogging ( 100 % vs -9 % , p < 0.001 ) , when compared with the flexibility-trained patients . The strength group also had greater improvements in Profile of Mood States dimensions : total mood disturbance ( 123 % vs 18 % , p < 0.05 ) , depression/dejection ( 73 % vs 15 % , p < 0.05 ) , and fatigue/inertia ( 42 % vs 3 % p < 0.05 ) , than did the flexibility group . The Medical Outcome Survey Short Form 36 role emotional health domain scores were significantly improved in the strength group when compared with the flexibility group ( 64 % vs 0 % , p < 0.05 ) , and the role limitation scores improved in both groups . Increases in strength were associated with enhanced self efficacy and improved mood and well-being scores ( n = 34 , r = 0.30 to 0.53 , p < 0.05 ) . High-intensity strength training added to a cardiac rehabilitation program of selected patients leads to improvements in quality -of-life parameters . These data , in conjunction with improvements in strength , strongly support the value of adding high-intensity strength training to cardiac rehabilitation programs
