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 free leucine supplementation and resistance training on muscle strength and functional status in older adults: a randomized controlled trial
Objective To assess the effect of free leucine supplementation combined with resistance training versus resistance training only on muscle strength and functional status in older adults . Methods This was a r and omized , double-blind , placebo-controlled , parallel study with two intervention groups . Thirty older adults were r and omly assigned to receive either 10 g leucine/day ( leucine group [ LG ] , n=15 ) or a placebo ( control group [ CG ] , n=15 ) , plus resistance training over a 12-week period . Maximal overcoming isometric leg strength , functional status , nutritional status , body composition , health-related quality of life , depression , and dietary intake were assessed at 4 and 12 weeks . Missing data at 12 weeks were h and led using mixed models for repeated measurements for data imputation . Results Twenty-four subjects completed the 4-week assessment and eleven completed the 12-week intervention . Clinical ly significant gains were found in isometric leg strength at both assessment time points . Analysis of the effect size also showed how participants in LG outperformed those in CG for chair st and s and the timed up and go test . No significant changes were observed for the rest of the outcomes . Conclusion Our combined analysis showed moderate changes in isometric leg muscle strength and certain components of functional status . The magnitude of changes found on these outcomes should be qualified as a positive effect of the concomitant intervention
