Vitamin D insufficiency is a problem of growing concern, given its prevalence in older persons and the association of low vitamin D with multiple major health problems, including mobility and balance deterioration and falls, cardiovascular disease, diabetes, and certain cancers. Sedentary persons are particularly vulnerable for these health problems and generally not adherent to prescribed physical activity. This study will investigate if treatment with vitamin D will benefit physical performance in male veterans age 65 to 95.

Change in Short Physical Performance Battery Test Score
The short physical performance battery (SPPB) examines 3 areas of lower extremity function: static balance test, gait speed test and getting in and out of a chair test. The total SPPB score is the sum of the scores of the 3 components and can range from 0 to 12, with 0 reflecting severe limitations and 12 minimal or no limitations. The ranges for each subscale are: balance (0-4), gait speed (0-4), sit-to-stand (0-4). In all the subscales, 0 reflects worse outcome and 4 best outcome.
