Purpose: However, the aim of the present study was to investigate the interactive effect of acute aerobic exercise with vitamin D supplementation on serum levels of 25-hydroxyvitamin D, insulin, glucose and insulin resistance in overweight girls.
Materials & method: The study population consisted of female students of Guilan University, of whom 16 with a body mass index of 25 to 30 kg / cm2 were randomly divided into two groups of supplements (8) and placebo (8). Each group performed one gel capsule (10,000 units) supplemented with vitamin D3 and placebo (sesame oil) and two rounds of acute aerobic exercise each week for 4 weeks through a treadmill that exhausted the treadmill. Then, in four different time intervals, 5 cc of blood samples were taken from the subjects' brachial vein.
Results: The results showed that the effect of time and group effect on 25 hydroxyvitamin D, insulin and glucose variables was significant in the supplement group (P ≤ 0.05), while in the control group there was no significant difference in these variables (P≥ 0.05). The results also showed that the interactive effect of time in the group was significant in the research variables (P ≤ 0.05).
Conclusion: According to the results, it can be said that increasing serum levels of 25-hydroxyvitamin D may improve glucose metabolism and insulin resistance in overweight girls through supplementation.
