Outline of Final Research Achievements

Recent studies suggest that vitamins AND minerals, which have antioxidant properties, enhances muscle strength and has prophylactic activity against bone fractures, osteoporosis, and decreases in physical performance. A cross-sectional study conducted in 2006 on community-dwelling elderly women suggested that high blood concentrations of vitamin C is associated with improved physical performance. This was done by conducting a follow-up survey in 2013 using the 2006 survey results as a baseline in order to provide a longitudinal analysis with a higher level of evidence.
In community-dwelling women, the concentration of blood vitamin C related well to their physical performance. The association between baseline concentration of vitamin C and seven year change in physical function showed that maximal walking speed significantly increased.
