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 .
Periodized resistance training with and without supplementation improve body composition and performance in older men
Purpose To examine the effects of 12 weeks of periodized resistance training ( RT ) with and without combined creatine and whey protein supplementation on changes in body composition , muscular strength , and functional performance . Methods Twenty-two male volunteers ( 68.1 ± 6.1 years ) were r and omly assigned to one of three groups : RT plus supplementation ( RTS , n = 7 ) ; RT only ( RT , n = 7 ) ; or control ( C , n = 8) . RTS consumed 0.3 g/kg/day of creatine for 5 days followed by 0.07 g/kg/day . RTS also consumed one 35 g liquid protein ready-to-drink daily . RT and RTS trained 3 days/week . Results Following 12 weeks of training , there were no significant differences in the main measured outcome variables between RT and RTS . RTS increased relative ( % change ) lean body mass ( LBM , 3.3 ± 3.1 % ) compared with C ( p = 0.01 ) . Compared to baseline , RT increased LBM at week 6 ( 60.2 ± 8.3 to 61.6 ± 9.4 kg ; p < 0.05 ) , and decreased fat mass ( 20.8 ± 4.2 to 19.0 ± 3.9 kg ; p = 0.05 ) and percentage body fat at week 12 ( 25.7 ± 3.8 to 23.8 ± 4.0 % ; p = 0.05 ) ; RTS increased LBM at week 6 ( p < 0.01 ) and week 12 ( 56.4 ± 4.3 to 58.2 ± 3.4 kg ; p < 0.01 ) , and decreased percentage body fat at week 12 ( 23.9 ± 4.4 to 22.0 ± 4.4 % ; p < 0.01 ) . In addition , compared to C , relative bench press 1-RM increased for RTS ( 72.4 ± 62.2 % ; p < 0.01 ) and RT ( 50.1 ± 21.5 % ; p = 0.05 ) ; relative leg press 1-RM increased for RTS ( 129.6 ± 39.4 % ; p < 0.0001 ) and RT ( 112.9 ± 22.7 % ; p < 0.0001 ) ; RTS increased relative Margaria stair-climbing power ( 38.3 ± 30.4 % ; p < 0.05 ) ; and , relative 400-m walk time decreased for RT ( −11 ± 9.2 % ; p < 0.05 ) and RTS ( −9.6 ± 9.4 % ; p = 0.05 ) . RT increased estimated VO2Max at week 6 ( p < 0.01 ) and 12 ( 34.6 ± 1.9 to 36.4 ± 2.7 ml/kg/min ; p = 0.01 ) compared to baseline . Lastly , RTS increased estimated VO2Max at week 12 ( 36.3 ± 2.7 to 37.5 ± 3.3 ml/kg/min ; p = 0.05 ) compared to baseline . Conclusion Creatine and whey protein supplementation may not provide additional benefits in older adults performing periodized RT to augment muscular and functional performance
