The effectiveness of vitamin D supplementation with Pilates Training on vitamin D status in overweight men. A clinical trial study

Aims: VitaminD deficiency is a common problem, and it is related to increased risk of metabolic syndrome and cardiovascular disease. But vitaminD has a beneficial effect on insulin secretion. The aim of this study was to investigate the effectiveness of vitaminD supplementation with Pilates training on vitaminD status and insulin resistance in overweight men. Materials & Methods: This quasi-experimental study was conducted in ۵۰ men (۴۵-۵۵years) with overweight. Volunteers were selected through convenience sampling and were divided into Pilates training, VitaminD, combined, and control groups. The Pilates program was performed ۳sessions/week, ۶۰-۷۵ minutes for session, with the intensity of ۵۰-۷۵% of reserve heart rate. The oral VitaminD received ۵۰۰۰۰ units of weekly. Data was analyzed by paired t, ANOVA and KruskalWallis tests with a p-value less than ۰.۰۵. Findings: According findings, ۶۰% and ۴۰% of the subjects had deficienciy and insufficient levels of vitaminD, respectively. ۸ weeks of Pilates training, VitaminD consumption and the combined intervention were associated with a significant increase in ۲۵(OH)D and decreased glucose, insulin, and IR (P<۰.۰۵). But the effect of combination interventions and VitaminD consumption was greater on increasing levels of ۲۵(OH)D than Pilates training. Combination intervention was also associated greater decrease in insulin and IR compared with VitaminD supplementation (P<۰.۰۵).  Conclusion: It seems that VitaminD, Pilates training and a combination of these interventions can improve the glycemic status and VitaminD in overweight people with low levels of vitaminD. Therefore, maintaining a normal status of vitamin D helps to develop the health of overweight people.
