Effect of Vitamin D Supplementation on Muscle Mass and Function

Obesity Clinical Trial

Official title:
Impact of Vitamin D Supplementation on Strength and Lean Mass Accumulation During an Exercise Intervention

Clinical Trial Summary

The study was designed to assess the effects of vitamin D supplementation during exercise training on body composition, muscle function, and glucose tolerance. The investigators hypothesis for these studies is that vitamin D supplementation enhances exercise-induced increases in strength and lean mass, potentially through enhancing insulin sensitivity and reducing inflammation.

Clinical Trial Description

The study was designed to assess the effects of vitamin D supplementation during exercise training on body composition, muscle function, and glucose tolerance. It was a double-blind, randomized, placebo-controlled, clinical trial with participants randomized into either a 4,000 IU/day vitamin D or placebo group and all participants completed 12 wks (3 d/wk) of exercise training. ;
