Abstract :
Introduction: Dipeptidyl peptidase-4 (DPP-4), is related to many metabolic diseases such as obesity. The purpose of this study was to investigate the effect of eight weeks of endurance training on the serum level of DPP-4, endurance performance and some anthropometric indicators in obese women. Materials and Methods: 23 inactive obese women aged 30 to 45 with a BMI of 30.5±5.37 who voluntarily and purposefully participated in the study. The subjects were randomly divided into two experimental groups (N=12) and control (N=11). First, pre-test measurements related to blood sample, height, weight, BMI, fat percentage, VO2max and waist to hip ratio of the subjects were performed. Then, the experimental group participated in 8 weeks of endurance training and the measurements of the post-test were recorded. MANCOVA test was used to check the significance of the difference between the groups. Results: The results showed that there is no significant difference between the research variables in the pre-test (p<0.05). MANCOVA showed that there was a significant decrease in weight (P=0.001), BMI (P=0.001), fat percentage (P=0.001) and DPP-4 (0.001) =P), and there is a significant increase in the amount of maximum oxygen consumption (P=0.038) after the end of the study in training group compared to the control group. Conclusion: It was found that eight weeks of endurance training reduces the serum level of DPP-4 and improves body composition and endurance performance in obese women. Therefore, it is suggested that obese women use these exercises to improve their health, body composition and increase their endurance capacity.
