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 .
Oral amino-acid provision does not affect muscle strength or size gains in older men.
PURPOSE The intent of this investigation was to examine the effects of a daily oral provision consisting of amino acids ( L-lysine , L-leucine , L-valine , L-phenylalanine , L-threonine , L-histidine , L-isoleucine , and L-methionine ) in combination with carbohydrates ( dextrose , sucrose , and fructose ) on whole muscle strength and size characteristics during a 12-wk progressive knee extensor resistance training ( PRT ) program in older men ( > 65 yr ) . METHODS Seventeen older men were r and omly assigned to either the experimental ( EX ) or control ( CN ) groups . The EX ( N = 8) and CN ( N = 9 ) groups had the following characteristics-EX : 70.8 + /- 1.5 yr , 91.0 + /- 4.9 kg , and 177.0 + /- 3.9 cm ; CN : 72.1 + /- 1.9 yr , 75.4 + /- 4.7 kg , and 176.1 + /- 3.0 . Pre and post PRT maximal unilateral isometric torque ( N.m ) , isokinetic torque ( 1.05 , 1.57 , 2.09 , 3.14 , 4.19 , and 5.24 rad.s-1 ) , work capacity ( 30 consecutive reps at 3.14 rad.s-1 ) torque , one repetition maximum ( 1RM ) bilateral isotonic strength , and whole muscle cross-sectional area ( CSA ) of the mid-thigh were performed by computed tomography on each subject . RESULTS All variables showed an improvement with training ( P < 0.05 ) ; however , there were no differences between the groups . Both groups increased in isometric strength by 21 % , and isokinetic torque by 24 % to 11 % with the varying velocities ( 1.05 - 5.24 rad.s-1 ) . Whole muscle 1RM strength and thigh CSA increased 50 % and 6.5 % , respectively . Additionally , voluntary torque/CSA increased 12 % in both the EX and CN groups ( P < 0.05 ) . CONCLUSIONS In conclusion , these data suggest that whole muscle strength and size are not enhanced with a postexercise daily provision of an oral amino-acid complex during 12 wk of PRT in older men
