Abstract

Introduction: Different physical exercises play an important role in energy balance and weight control through affecting the appetite-regulating hormones. The aim of this study was to determine the effect of different resistance training modes on appetite and appetite-related hormones among sedentary healthy males. Subjects & Methods: This study was conducted on 40 healthy males with the mean age of 22.15±0.7 years and body mass index of 24.12±3.5 kg/m2. The study population was randomly assigned into four groups of control group (n=10), upper-body resistance training (n=10), lower-body resistance training, and full body resistance training. Trainings were performed three sessions a week for eight weeks. The fasting blood samples were obtained from the antecubital vein before and 48 h after the last session of the resistance training for the evaluation of plasma growth hormone, orexin, ghrelin, acyl ghrelin, and neuropeptide Y (NPY) using ELISA method. In addition, the desire to eat was measured by means of the appetite questionnaire. Results: According to the results, plasma growth hormone, orexin, ghrelin, and acyl ghrelin were increased significantly after lower-body and full body resistance trainings, compared to the pre-intervention stage. Meanwhile, the upper-body resistance training just resulted in the elevation of NPY (P=0.049). The enhancement of orexin level was more significant in the lower-body training group in comparison to that in the control group (P=0.001). Furthermore, the enhancement of ghrelin level was more significant in the full body (P=0.021) and lower-body (P=0.001) training groups than in the control group. On the other hand, the three intervention groups showed a higher elevation in NPY as compared to the control group. Additionally, desire to eat was increased after the three modes of training; however, there was no significant difference among the three training groups in this regard. Conclusion: As the findings indicated, resistance training, especially lower-body and full body resistance trainings, regulated appetite through the elevation of growth hormone, orexin, ghrelin, and NPY. Moreover, the type of resistance training affected the amount of appetite changes after adjusting to resistance training.
