Ghrelin Concentration Changes Response to Regular Resistance Exercise Training

According to the prevalence of obesity and its complications in Iran and worldwide, the cognition of effective methods that reduce the risk factors and implications in obese persons can have significant clinical appliances. Hence, the aim of this study was to determine the effects of 12 weeks of regular resistance exercise training on plasma levels of ghrelin in the obese men.
Material and Twenty obese men (BMI≥ 30, 18-32 years)) were selected and randomly divided in to the two resistance training (n=10) and control (n=10) groups. Resistance training was performed three times a week on alternate days for 12 weeks and included 8 exercises. At baseline and after last training session, blood samples were taken in 12-14 hours fasting state from all subjects and ghrelin plasma levels before and after the protocol were measured. The paired and unpaired t-tests were used for statistical analysis P value Compared to pre-training, after 12 weeks of regular exercise training, the plasma ghrelin levels significantly increased (P0.05).
The results of this study indicated that the long term exercise training significantly increases the ghrelin plasma levels. Hence, it is recommended that this type of training can be used as an effective and low-cost therapeutic method to control the body composition in the obese men.
