Abstract

BACKGROUND AND OBJECTIVES: Vitamin D is an established important contributor to muscle function and aerobic metabolism. Hypovitaminosis D is highly prevalent in CKD patients and is associated with increased cardiovascular (CV) mortality via unknown mechanisms. Because aerobic-exercise capacity strongly predicts future CV events, we hypothesized that vitamin D status could be linked to CV outcomes via an effect on maximum aerobic-exercise capacity in patients with CKD and that this effect may be mediated in part via its actions on muscle strength and functional ability. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Baseline demographic, anthropometric, and biochemical data were collected in ..
