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 .
Long-term creatine supplementation improves muscular performance during resistance training in older women
This study examined the effects of long-term creatine supplementation combined with resistance training ( RT ) on the one-repetition maximum ( 1RM ) strength , motor functional performance ( e.g. , 30-s chair st and , arm curl , and getting up from lying on the floor tests ) and body composition ( e.g. , fat-free mass , muscle mass , and % body fat using DEXA scans ) in older women . Eighteen healthy women ( 64.9 ± 5.0 years ) were r and omly assigned in a double-blind fashion to either a creatine ( CR , N = 9 ) or placebo ( PL , N = 9 ) group . Both groups underwent a 12-week RT program ( 3 days week−1 ) , consuming an equivalent amount of either creatine ( 5.0 g day−1 ) or placebo ( maltodextrin ) . After 12 week , the CR group experienced a greater ( P < 0.05 ) increase ( Δ% ) in training volume ( + 164.2 ) , and 1RM bench press ( + 5.1 ) , knee extension ( + 3.9 ) and biceps curl ( + 8.8 ) performance than the PL group . Furthermore , CR group gained significantly more fat-free mass ( + 3.2 ) and muscle mass ( + 2.8 ) and were more efficient in performing submaximal-strength functional tests than the PL group . No changes ( P > 0.05 ) in body mass or % body fat were observed from pre- to post-test in either group . These results indicate that long-term creatine supplementation combined with RT  improves the ability to perform submaximal-strength functional tasks and promotes a greater increase in maximal strength , fat-free mass and muscle mass in older women
