The present review demonstrates that vitamin D supplementation result ed in small but nonsignificant improvements in muscle strength compared to control in postmenopausal women .
No significant effect was observed in mobility after vitamin D administration
BACKGROUND The results obtained from previous trials regarding the effects of vitamin D supplementation on muscle strength and mobility  in postmenopausal women have been inconsistent .
This systematic review and meta- analysis of r and omised controlled trials ( RCTs ) aim ed to investigate the effect of vitamin D supplementation on muscle strength and mobility in postmenopausal women .
Combination of alfacalcidol and calcium improved handgrip strength and mobility among Indonesian older women: A randomized controlled trial
AIM To determine the effect of alfacalcidol on muscle strength and functional mobility in Indonesian older women whose h and grip strength was low . METHODS A r and omized , double-blind controlled trial was carried out among 95 older women whose h and grip strength was ≤22 kg . Participants were r and omized into two groups : 47 participants received alfacalcidol 0.5 μg/day and 48 participants received a placebo . Each participant in both groups was given calcium 500 mg/day . H and grip strength as well as the Timed-Up and Go test were measured before and after 90 days of intervention . Per protocol analysis after intervention between two groups was carried out . RESULTS There was a significant improvement of h and grip strength in the group that received alfacalcidol compared with the placebo group ( 15.50 vs 13.75 ; P = 0.003 ) . The median time for the Timed-Up and Go test in the alfacalcidol group also improved significantly compared with the placebo group ( 9.01 vs 10.07 , P = 0.028 ) . CONCLUSIONS Alfacalcidol with daily doses of 0.5 μg significantly improved muscle strength and functional mobility in Indonesian older women . Geriatr Gerontol Int 2018 ; 18 : 434 - 440
