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 .
Effect of oral magnesium supplementation on physical performance in healthy elderly women involved in a weekly exercise program: a randomized controlled trial.
BACKGROUND Magnesium deficiency is associated with poor physical performance , but no trials are available on how magnesium supplementation affects elderly people 's physical performance . OBJECTIVE The aim of our study was to investigate whether 12 wk of oral magnesium supplementation can improve physical performance in healthy elderly women . DESIGN In a parallel-group , r and omized controlled trial , 139 healthy women ( mean ± SD age : 71.5 ± 5.2 y ) attending a mild fitness program were r and omly allocated to a treatment group ( 300 mg Mg/d ; n = 62 ) or a control group ( no placebo or intervention ; n = 77 ) by using a computer-generated r and omization sequence , and research ers were blinded to their grouping . After assessment at baseline and again after 12 wk , the primary outcome was a change in the Short Physical Performance Battery ( SPPB ) ; secondary outcomes were changes in peak torque isometric and isokinetic strength of the lower limbs and h and grip strength . RESULTS A total of 124 participants allocated to the treatment ( n = 53 ) or control ( n = 71 ) group were considered in the final analysis . At baseline , the SPPB scores did not differ between the 2 groups . After 12 wk , the treated group had a significantly better total SPPB score ( Δ = 0.41 ± 0.24 points ; P = 0.03 ) , chair st and times ( Δ = -1.31 ± 0.33 s ; P < 0.0001 ) , and 4-m walking speeds ( Δ = 0.14 ± 0.03 m/s ; P = 0.006 ) than did the control group . These findings were more evident in participants with a magnesium dietary intake lower than the Recommended Dietary Allowance . No significant differences emerged for the secondary outcomes investigated , and no serious adverse effects were reported . CONCLUSIONS Daily magnesium oxide supplementation for 12 wk seems to improve physical performance in healthy elderly women . These findings suggest a role for magnesium supplementation in preventing or delaying the age-related decline in physical performance
