Purpose: Exercise training may influence on appetite hormones and energy homeostasis. Aims: The purpose of the current study was to investigate the effect of resistance training with elastic band (ERT) on ghrelin (GHRL) and obestatin (OBST) hormones' concentration changes in overweight men. Methods: Twenty male overweight (25 < BMI ≤ 29.5 kg/m2) voluntary participated in the current study and randomly assigned in the resistance training with elastic bands (ERT; n = 10), and control (Con; n = 10). Elastic resistance training was done three sessions in week in non-consecutive for 8 weeks. Blood sample was gathered before ERT and was repeated 48 h interval with the last session of exercise training. GHRL and OBST were assessed in the plasma. Also, functional capacity (Push UP: PU; Squat: SQ) was assessed, and body fat percentage (BF %) was estimated. Results: We found that there was a significant difference in GHRL in the ERT than control [time × group (p = 0.045; F = 4.38)]; however, there was no significant difference in OBST (p˃0.05). It was also seen that the interactive effect of time in the ERT (time × group) was significant for PU and SQ [(p = 0.004; F = 8.02), and SQ (p = 0.011; F = 8.1], respectively. Also, a decrease was found in BF% in the ERT than control (p ≤ 0.001). Conclusion: Finally, it can be concluded elastic resistance training with elastic bands improve the functional capacities and ghrelin hormone, and should be taken into consideration in the design of weight control protocols. This implicitly states that stretching resistance training increases metabolism and improves calorie intake. [ABSTRACT FROM AUTHOR]
