Effect of Exercise Training on Omentin-1 and Vaspin: Comparison of Continuous Endurance, Circuit Resistance, and High Intensity Interval Trainings in Obese Young Men

Vaspin and Omentin are adipokines and seem to be related to metabolic risk factors. The purpose of the present study was to investigate the effects of continuous endurance training (CET), circuit resistance training (CRT), and high intensity interval training (HIT) on plasma levels of Omentin and Vaspin in obese young men.

A total of 44 obese young men voluntarily participated in the present study and were randomly divided into continuous endurance training (CET; n=11), circuit resistance training (CRT; n=11), high intensity interval training (HIT; n=11), and Control (Con; n=11) groups. CET was done with 70% VO2max. Also, HIT was performed with six three-minute sets of running at 90% of VO2max, while CRT was done at 11 stations with 20% 1RM, three times a week for 12 weeks. Blood samples were collected before and after training protocols and Omentin-1 and Vaspin were measured in the plasma. To compare between-group data, two-way ANOVA with repeated measurements and Bonferron's post hoc test were run.

The results showed that there is no significant difference between CET, HIT, and CRT in the Omentin-1 and Vaspin after training (p˃0.05). However, Omentin-1 increased significantly in the CRT (p=0.002) and HIT (p=0.011) compared with the controls. Also, Vaspin significantly decreased in the CRT compared with that in the control group (p=0.029).   

Finally, it can be stated that none of the continuous endurance, circuit resistance, and high intensity interval trainings is preferable to improve Vaspin and Omentin-1 although they can improve hormone levels after 12 weeks of exercise training.
