Abstract	The purpose of this study was to examine the effects of vitamin D supplementation on inflammatory biomarkers in overweight and obese adults participating in a progressive resistance exercise training program. Twenty-three (26.1±4.7 y) overweight and obese (BMI: 31.3±3.2 kg·m−2) adults were randomized into a double-blind vitamin D supplementation (VitD, 4000 IU/d, female=5; male=5) or placebo (PL, female=7; male=6) intervention trial. Both groups performed 12 wk (three d/wk) of progressive resistance exercise training (three sets of eight exercises) at 70 – 80% of one repetition maximum. Whole blood lipopolysaccharide (LPS)-stimulated tumor necrosis factor (TNF) α production as well as circulating C-reactive protein (CRP), TNFα, interleukin 6 (IL-6), and alanine aminotransferase (ALT) were assessed at baseline and after the 12 wk intervention. No main effects of group or time were detected for circulating CRP, TNFα, IL-6 and ALT. As expected, when PL and VitD groups were combined, there was a significant correlation between percent body fat and CRP at baseline (r=0.45, P=0.04), and between serum 25OHD and CRP at 12 weeks (r=0.49, P=0.03). The PL group had a significant increase in 25 μg/ml LPS+polymixin B-stimulated TNFα production (P=0.04), and both groups had a significant reduction in unstimulated TNFα production (P<0.05) after the 12 week intervention. Vitamin D supplementation in healthy, overweight and obese adults participating in a resistance training intervention did not augment exercise-induced changes in inflammatory biomarkers.
