Arm Label
Yogurt supplemented with vitamin D and calcium
Yogurt not supplemented with vitamin D and calcium

Outcomes
Primary Outcome Measures
Change in spatiotemporal gait, and in particular in the variability of stride time
Stride time variability is measured with spatiotemporal analysis of walking
Secondary Outcome Measures
Change in posture
Posture is evaluated with Time Up & Go, Five Time Sit-to-Stand and posture analysis with a platform.
Change in grip strength
Grip strength is measured with a dynamometer.
Change in executive performance
Executive performance is measured with Trial Making Test part B (TMT B)
Change in other cognitive scores
Executive scores are assessed with digit span test (forward and backward), Trial Making Test part A (TMT A), Stoop test and Processing Speed Index
Change in the serum concentration of 25 OHD
This outcome is assessed with the serum concentrations of 25OHD
Compliance to intervention
Compliance is measured by the number of yogurt capsules returned

5. Study Description
Brief Summary
Gait and posture disorders are very common in subjects aged 65 and over, and result mainly from neuromuscular and cognitive disorders.
Many studies have shown that 1) vitamin D deficiency is very common in women aged 65 and over, 2) individuals with hypovitaminosis D have lower muscle, gait and executive performances and are more prone to fail than individuals with no hypovitaminosis D, 3) the intake of vitamin D combined or not with calcium may improve muscle strength and cognitive performance.
The investigators hypothesized that the daily intake of 2 yogurts containing 200 IU of vitamin D and 400 mg of calcium 1) can improve spatiotemporal gait parameters, posture and executive performance, 2) and that this improvement depends of the initial level of vitamin D deficiency.
