Abstract

 Introduction: This study in restigates the effect of one session of swimming and running training on hunger rate and ghrelin, insulin and cortisol hormones of the plasma in the healthy girls. Materials and Methods: Twelve girls participated in three modes of control, swimming and running training at 80-85% intensity of maximum heart rate, up to exhuastion. The hunger rate of the individuals before taking blood and eight hours after the training was assessed through appetite questionnaires. Blood samples were taken before, immediately after and two hours after the training sessions. Results: No significant change was observed in the hunger rate immediately, or two and eight hours after the training after one session of swimming and running training whereas one session of swimming and running training increased ghrelin immediately and two hours after the training. Cortisol decreased in three stages, immediately and two hours after the training in comparison withbase line levels, a reduction lower than that of controls. One session of swimming and running training prevented any significant rise in insulin. Conclusion: Swimming and running training causes ghrelin to increase, but has no effect on hunger rate.
