Backgrand and Objective: Low levels of 25-Hydroxyvitamin D are associated with obesity and anthropometric indices. Therefore, the aim of this study was to determine the effect of aerobic interval exercise training on serum levels of 25-OH Vitamin D and anthropometric indices in obesity and overweight women. Subjects and Methods: In this research semi-experimental study, 20 obese and overweight women aged between 30 to 50 years. and mean BMI of 31.71 ± 2.59 Kg / m2 referring to the Ahvaz Jundishapur University Clinic were selected purposefully. and randomly They were divided into intervention and control groups.

Anthropometric and serum level of 25-hydroxyvitamin D were measured before and after intervention in both groups. Data analysis was performed using independent and dependent t test at a significant level (P ≤0.05) Results: After eight weeks of of aerobic interval exercise training, a significant increase was observed in levels serum 25- hydroxyvitamin D (P=0.002). Which was associated with a significant decrease in body fat percentage, waist to hip ratio and body mass index in overweight and obese women (P <0.05).
