Results indicate that physical exercise has a positive impact on muscle mass and muscle function in subjects aged 65 years and older .
Conclusion Physical exercise has a positive impact on muscle mass and muscle function in healthy subjects aged 60 years and older .
The biggest effect of exercise intervention , of any type , has been seen on physical performance ( gait speed , chair rising test , balance , SPPB test , etc . )
.
We observed huge variations in regard to the dietary supplementation protocol s. Based on the included studies , mainly performed on well-nourished subjects , the interactive effect of dietary supplementation on muscle function appears limited
Summary This systematic review summarizes the effect of combined exercise and nutrition intervention on muscle mass and muscle function .
However , any interactive effect of dietary supplementation appears to be limited .
Introduction In 2013 , Denison et al. conducted a systematic review including 17 r and omized controlled trials ( RCTs ) to explore the effect of combined exercise and nutrition intervention to improve muscle mass , muscle strength , or physical performance in older people .
They concluded that further studies were needed to provide evidence upon which public health and clinical recommendations could be based .
The purpose of the present work was to up date the prior systematic review and include studies published up to October 2015 .
The effects of exercise and protein-energy supplements on body composition and muscle function in frail elderly individuals: a long-term controlled randomised study.
Fighting against inactivity and inadequate nutritional intake are of utmost importance in the elderly . To our knowledge , the few studies which have been performed were conducted for only a short period and the results do not permit formal conclusions to be drawn . We therefore tried to fill this gap in our knowledge by determining whether an intervention combining an acceptable progressive exercise programme and nutritional supplements would be feasible for a long-term period in the very frail elderly , and would bring about concomitant benefits in body composition and muscle power . Accordingly , this exercise and nutritional combination was assessed in the frail elderly in a 9-month r and omised trial with a factorial design . Fifty-seven elderly volunteers over 72 years , from sixteen retirement homes in Lyon , France participated in the study .  Dietary supplements were compared with placebo , and physical exercise was compared with memory training . Main outcome measures were fat-free mass ( FFM ) and muscle power . FFM was determined by labelled water , and muscle power was measured by a leg-extensor machine . At 9 months , the compliance was 63 % for exercise sessions , and 54 % for nutritional supplements . In patients with dietary supplements , muscle power increased by 57 % at 3 months ( P=0.03 ) , and showed only a tendency at 9 months ; although FFM increased by 2.7 % at 9 months , the difference was not significant ( P=0.10 ) . Exercise did not improve muscle power at 9 months , but improved functional tests ( five-time-chair rise , P=0.01 ) . BMI increased with supplements ( + 3.65 % ) , but decreased with placebo ( -0.5 % ) at 9 months ( P=0.007 ) . A long-term combined intervention is feasible in frail elderly individuals with a good rate of compliance . Nutritional supplements and exercise may improve muscle function . Despite no significant results on FFM , due to the limited number of volunteers , combined intervention should be suggested to counteract muscle weakness in the frail elderly
