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

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.

This quasi-experimental study was conducted in 50 men (45-55years) with overweight. Volunteers were selected through convenience sampling and were divided into Pilates training, VitaminD, combined, and control groups. The Pilates program was performed 3sessions/week, 60-75 minutes for session, with the intensity of 50-75% of reserve heart rate. The oral VitaminD received 50000 units of weekly. Data was analyzed by paired t, ANOVA and KruskalWallis tests with a p-value less than 0.05.

According findings, 60% and 40% of the subjects had deficienciy and insufficient levels of vitaminD, respectively. 8 weeks of Pilates training, VitaminD consumption and the combined intervention were associated with a significant increase in 25(OH)D and decreased glucose, insulin, and IR (P<0.05). But the effect of combination interventions and VitaminD consumption was greater on increasing levels of 25(OH)D than Pilates training. Combination intervention was also associated greater decrease in insulin and IR compared with VitaminD supplementation (P<0.05).

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.
