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 .
Creatine supplementation and resistance training in vulnerable older women: A randomized double-blind placebo-controlled clinical trial
This study aim ed to examine the efficacy of creatine supplementation , associated or not with resistance training , in vulnerable older women . A 24-week , double-blind , r and omized , placebo-controlled trial was performed . Sixty subjects were assigned to compose the following groups : placebo ( PL ) , creatine supplementation ( CR ) , placebo with resistance training ( PL+RT ) , and creatine supplementation with resistance training ( CR+RT ) . The subjects were assessed at baseline and after 24weeks . The primary outcome was muscle strength , as assessed by one-repetition maximum ( 1-RM ) tests . Secondary outcomes included appendicular lean mass , bone mass , biochemical bone markers , and physical function tests . The changes in 1-RM leg press were significantly greater in the CR+RT group ( + 19.9 % ) than in the PL ( + 2.4 % ) and the CR groups ( + 3.7 % ) , but not than in the PL+RT group ( + 15 % ) ( p=0.002 , p=0.002 , and p=0.357 , respectively ) . The CR+RT group showed superior gains in 1-RM bench press ( + 10 % ) when compared with all the other groups ( p≤0.05 ) . The CR+RT group ( + 1.31 % ) showed greater appendicular lean mass accrual than the PL ( -1.2 % ) , the CR ( + 0.3 % ) , and the PL+RT groups ( -0.2 % ) ( p≤0.05 ) . The CR and the PL+RT groups experienced comparable gains in appendicular lean mass ( p=0.62 ) , but superior to those seen in the PL group . Changes in fat mass , bone mass and serum bone markers did not significantly differ between the groups ( p>0.05 ) . In conclusion , creatine supplementation combined with resistance training improved appendicular lean mass and muscle function , but not bone mass , in older vulnerable women .
