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 with elastic bands: measure of its effects in cardiac rehabilitation after coronary diseases].
OBJECTIVES To compare high intensity strength training with weightlifting exercises or with elastic b and s. SETTING Outpatient unit of cardiac rehabilitation . TYPE : Prospect i ve r and omised clinical trial . POPULATION Inclusion of coronary patients in phase II after medical or surgical treatment of a myocardiac infa rct ion , without cardiac insufficiency ; beta-blockers were accepted . METHOD Evaluation of coronary patients at beginning and at the end of a 4 week cardiac rehabilitation program . It included progressive aerobic training according to Karvonen method for all the patients , associated with weightlifting exercises ( Koch press ) in the control group , or use of elastic b and s in the experimental group .  Cardiac rate , oxygen consumption at rest and at maximum power were the main criteria with also muscle strength of quadriceps , hamstrings , biceps brachii , latissimus dorsi and triceps brachii , body mass indexes , quality of life with SF-36 , anxiety ( stay T test ) and perceived exertion with the Borg 10-point category-ratio scale , myotendinous injuries ( Shaw scale ) . RESULTS Twenty-six coronary patients , all male from 45 to 65 years old , all receiving beta-blockers , were included , 13 in each group . Control and experimental groups were initially similar . At the end of the 4 week program , all the two groups improved significantly their strength and power and there were no differences between the two groups . Perceived exertion was lower in the group using elastic b and s and there were no myotendinous lesions . CONCLUSION Strength training with elastic b and s is a low-cost , attractive , playful technique , proposed to a group of coronary patients , which appears as effective in cardiac rehabilitation as individual weightlifting training
