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 vitamin D supplementation and exercise training on physical performance in Chilean vitamin D deficient elderly subjects
The aim was to assess the effects of resistance training and vitamin D supplementation on physical performance of healthy elderly subjects . Ninety-six subjects , aged 70 years or more with 25 OH vitamin D levels of 16 ng/ml or less , were r and omized to a  resistance training or control group . Trained and control groups were further r and omized to receive in a double blind fashion , vitamin D 400 IU plus 800 mg of calcium per day or calcium alone . Subjects were followed for nine months . Serum 25 OH vitamin D increased from 12.4+/-2.2 to 25.8+/-6.5 ng/ml among subjects supplemented with vitamin D. Trained subjects had significant improvements in quadriceps muscle strength , the short physical performance test and timed up and go . The latter improved more in trained subjects supplemented with vitamin D. At the end of the follow up , gait speed was higher among subjects supplemented with vitamin ( whether trained or not ) than in non-supplemented subjects ( 838+/-147 and 768+/-127 m/12 min , respectively , p=0.02 ) . Romberg ratio was lower among supplemented controls than non-supplemented trained subjects ( 128+/-40 % and 144+/-37 % , respectively , p=0.05 ) . In conclusion , vitamin D supplementation improved gait speed and body sway , and training improved muscle strength
