The Effect of 12 Weeks Aerobic Exercise Training on Visfatin, Chemerin Serum Changes in 45-60 year old Obese Women with Type2 Diabetes

Adipocytokine including chemerin and visfatin have a key role in metabolic regulations, as well as obesity-related disorders such as type 2 diabetes. The aim of this study was to investigate the effect of the 12-week exercise training on changes in levels of visfatin and chemerin in obese women with type 2 diabetes.
In this study, 30 overweight women with the age range of 45-60 years old were selected and ther were divided into the control group (n = 15), and the experimental group (n = 15) which had no significant differences based on the body fat percentage and the body mass index. Exercise program consisted of increasing aerobic exercise three times were for 12 weeks. To measure Chemerin and Visfatin, blood samples before and 24 hours after the last training session were collected. Data evaluation was performed using ANCOVA to compare the pre-test and post-test in each group.
According to the obtained results, there was no significant difference between weight, body mass index, lean body weight, fat mass and fat percentage, but the chemerin levels have been increased significantly (p=0.0001) and also visfatin and glucose levels have been decreased (respectively p=0.0001 and p=0.001).
Aerobic activities are a stimulating factor for increasing in the chemerin hormone and also a stimulating factor for decreasing in the Visfatin hormone. It could be said that regular aerobic activities in 12 weeks are a good stimulating factor for creating changes in these hormones in women with diabetes and it is probably one of the contributing factors of physiologic changes resulted from these exercise activities is changes in these hormones.
