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 macronutrient intake on thigh muscle mass during home-based walking training in middle-aged and older women.
We examined whether post-exercise macronutrient supplementation during a 5-month home-based interval walking training ( IWT ) accelerated exercise-induced increases in skeletal muscle mass and strength in healthy middle-aged and older women . Thirty-five women ( 41 - 78 years ) were r and omly divided into two groups : IWT alone ( CNT , n = 18 ) or IWT plus post-exercise macronutrient ( 7.6 g protein , 32.5 g carbohydrate , and 4.4 g fat ) supplementation ( NUT , n = 17 ) . For IWT , all subjects were instructed to repeat five or more sets of 3-min low-intensity walking at 40 % peak aerobic capacity ( Vo2 peak ) , followed by a 3-min high-intensity walking above 70 % Vo2 peak per day for 4 or more days per week . We determined Vo2 peak , thigh muscle tissue area by computer tomography , and thigh muscle strength in all subjects before and after IWT . We found that an increase in hamstring muscle tissue area was 2.8 ± 1.2 % in NUT vs -1.0 ± 0.7 % in CNT and that in isometric knee flexion force was 16.3 ± 3.7 % in NUT vs 6.5 ± 3.0 % in CNT ; both were significantly higher in NUT than in CNT ( both , P < 0.001 ) . Thus , post-exercise macronutrient supplementation enhanced the increases in thigh muscle mass and strength , although partially , in home-based IWT in middle-aged and older women
