| 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.
