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 .
Does Nutritional Supplementation Influence Adaptability of Muscle to Resistance Training in Men Aged 48 to 72 Years
Background and Purpose : Isotonic strength training can result in neuromuscular improvements evidence d in other forms of muscular effort , ie , isokinetic or isometric , especially in young subjects ; however , it is unclear if older muscle maintains this same adaptive ability . Additionally , it is not known if the benefits of resistance training can be augmented by creatine and protein supplementation in older men . Therefore , the purpose of this study was to assess changes in isokinetic parameters at varying speeds in men aged 48 to 72 years ( mean = 57 ± 2.1 ) following 16 weeks of isotonic resistance training and creatine and /or protein supplementation . Methods : Forty‐two male subjects were r and omly assigned to 1 of 4 training groups : ( 1 ) resistance training placebo ( n = 10 ) , ( 2 ) resistance trained creatine supplemented ( n = 10 ) , ( 3 ) resistance trained protein supplemented ( n = 11 ) , and ( 4 ) resistance trained creatine and protein supplemented ( n = 11 ) . The program consisted of progressive overload resistance training ( 3 d/wk ) and supplement consumption following the workout . Results : There were significant time effects ( P ≤ .05 ) for peak torque ( PT ) , time to PT , and average power for both the knee extensors and flexors at all velocities . However , no significant group or group by time interactions were noted , indicating that the supplementation protocol s had no added benefits . Conclusions : Men aged 48 to 72 years maintained their ability to improve isokinetic muscle function following isotonic training , however , supplementation did not enhance muscle adaptability
