compare the effect of 12 weeks of selected exercises and vitamin D on the serum visfatin level and beta cell function in women with overweight type II diabetes.

Visfatin is an insulin-like protein derived from adipose tissue that is associated with obesity and insulin resistance. The purpose of this study was to compare the effect of 12 weeks of selected exercises and vitamin D on the serum visfatin level and beta cell function in women with overweight type II diabetes. 40 type 2 diabetic women with a mean age of 1.49 ± 3.65 years, weight 158.15 ± 5.65 cm and body mass index 29.4 ± 0.46 kg / m2 were selected purposefully. Three groups of experimental (combined exercise, vitamin D, combined exercise with vitamin D) and a control group were randomly assigned into four groups of 10. Height, weight, BMI and fat percentage of subjects were measured. After 12 hours of fasting, the primary blood sample was taken to measure glucose, insulin, visfatin, insulin resistance, and beta cell function. Subjects then participated in the experimental group 1 in the combined program. The experimental group, in addition to the combined exercises, consumed vitamin D 6 pills per 50,000 units a week. Experimental group 3 consumed only vitamin D with 6 pills per dose of 50,000 units per week and did not have any training. The control group was only tracked. After 12 weeks, all variables were re-measured in 4 groups . The t-test was used to compare the intergroup ANOVA was used to compare the group. The results showed that after 12 weeks, there was a significant difference in serum visfatin, beta cellular activity, glucose and fasting insulin, insulin resistance, and body composition (p≤0.05).   The findings of this study emphasize the effect of combined exercises on reducing blood glucose in overweight women, and these exercises can be used to reduce blood glucose levels.
