| Research Abstract |
Vitamin D deficiency is highly prevalent in our study sample.In a cross-sectional study, we found that objectively measured physical activity and VO2max are independently and positively related to serum vitamin D status. Twelve months supplementation significantly improved 25(OH)D status in the vitamin D group compared to no changes in the Placebo group. However, the increase in 25(OH)D concentration in the vitmin D group did not result in signifi cant increases in VO2max.
