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 .
Body composition in 70-year-old adults responds to dietary beta-hydroxy-beta-methylbutyrate similarly to that of young adults.
Studies in young adults have demonstrated that beta-hydroxy-beta-methylbutyrate ( HMB ) can increase gains in strength and fat-free mass during a progressive resistance-training program . The purpose of this study was to determine whether HMB would similarly benefit 70-y-old adults undergoing a 5 d/wk exercise program . Thirty-one men ( n = 15 ) and women ( n = 16 ) ( 70 + /- 1 y ) were r and omly assigned in a double-blind study to receive either capsules containing a placebo or Ca-HMB ( 3 g/d ) for the 8-wk study . Skin fold estimations of body composition as well as computerized tomography ( CT ) and dual X-ray absorptiometry ( DXA ) scans were measured before the study and immediately after the 8-wk training program . HMB supplementation tended to increase fat-free mass gain ( HMB , 0.8 + /- 0.4 kg ; placebo , -0.2 + /- 0.3 kg ; treatment x time , P = 0.08 ) . Furthermore , HMB supplementation increased the percentage of body fat loss ( skin fold : HMB , -0.66 + /- 0.23 % ; placebo , -0.03 + /- 0.21 % ; P = 0.05 ) compared with the placebo group . CT scans also indicated a greater decrease in the percentage of body fat with HMB supplementation ( P < 0.05 ) . In conclusion , changes in body composition can be accomplished in 70-y-old adults participating in a strength training program , as previously demonstrated in young adults , when HMB is supplemented daily
