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 .
Effects of whey proteins and carbohydrates on the efficacy of resistance training in elderly people: double blind, randomised controlled trial
Background / objectives : A few previous studies indicate that protein supplementation increases gains in muscle mass and strength during a resistance exercise program . The purpose of this study was to investigate whether whey protein supplementation results in greater increases in lean body mass , muscle strength and physical function in elderly individuals during 12 weeks of resistance exercise when compared to isocaloric carbohydrate supplementation . Subjects/ Methods : A total of 161 men and women , 65–91 years old , participated in a r and omized , controlled , double-blind intervention study , involving dietary supplementation and a 12-week resistance exercise program , design ed to increase muscle mass and strength of all major muscle groups . Participants exercised three times a week and received either 20 g of whey protein ( n=83 ) or isocaloric carbohydrate ( n=78 ) in liquid form immediately after each workout . Data were obtained at baseline and end point . Results : The primary outcomes , lean body mass , strength and physical function increased significantly during the course of the study . Type of dietary supplementation did not influence gains in lean body mass ( P=0.365 ) , quadriceps strength ( P=0.776 ) or performance during a 6-min walk ( P=0.726 ) or a timed up- and -go test ( P=0.151 ) . Twenty participants discontinued the intervention . Conclusions : Ingestion of 20 g of whey protein immediately after resistance exercise three times per week , does not lead to greater gains in lean body mass , strength and physical function in elderly people with sufficient energy and protein intakes when compared to isocaloric carbohydrate
