Abstract :
Aim: Exercise training (ET) may affect appetite-regulating factors. The purpose of current study was to investigate the effect of order of resistance training (RT) on ghrelin and obstatin hormones changes in obese women. Methods: For this purpose, 30 obese female subjects voluntarily participated in the present study and were randomly assigned to three resistance training: pyramid (Low to high; n=10), Oxford (high to low; n=10) and control (n=10).RT was performed in three non-consecutive sessions per week for eight weeks.Before starting the exercise training program, and 72 hours after the last training session, blood sampling was gathered and the ghrelin and obstatin hormones concentration in plasma were measured. Also, changes in body fat percentage (BF %) were measured by skinfold test. Results: The results showed that there was no significant difference between pyramid and Oxford RT in the ghrelin and obstatin in the interaction between the effect of time (exercise) (p>0.05). Conclusion: Finally, it can be said that intensity order of resistance training as form pyramid and Oxford is not effective on appetite regulating hormones. This issue can be used in the designing of resistance exercise program and weight control.
