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 Monohydrate and Conjugated Linoleic Acid Improve Strength and Body Composition Following Resistance Exercise in Older Adults
Aging is associated with lower muscle mass and an increase in body fat . We examined whether creatine monohydrate ( CrM ) and conjugated linoleic acid ( CLA ) could enhance strength gains and improve body composition ( i.e. , increase fat-free mass ( FFM ) ; decrease body fat ) following  resistance exercise training in older adults ( > 65 y ) . Men ( N = 19 ) and women ( N = 20 ) completed six months of resistance exercise training with CrM (5g/d)+CLA ( 6g/d ) or placebo with r and omized , double blind , allocation . Outcomes included : strength and muscular endurance , functional tasks , body composition ( DEXA scan ) , blood tests ( lipids , liver function , CK , glucose , systemic inflammation markers ( IL-6 , C-reactive protein ) ) , urinary markers of compliance ( creatine/creatinine ) , oxidative stress ( 8-OH-2dG , 8-isoP ) and bone resorption ( Ν-telopeptides ) . Exercise training improved all measurements of functional capacity ( P<0.05 ) and strength ( P<0.001 ) , with greater improvement for the CrM+CLA group in most measurements of muscular endurance , isokinetic knee extension strength , FFM , and lower fat mass ( P<0.05 ) . Plasma creatinine ( P<0.05 ) , but not creatinine clearance , increased for CrM+CLA , with no changes in serum CK activity or liver function tests . Together , this data confirms that supervised resistance exercise training is safe and effective for increasing strength in older adults and that a combination of CrM and CLA can enhance some of the beneficial effects of training over a six-month period .
