Purpose: Exercise could reverse the positive energy balance by increased energy expenditure and hunger suppresses. Hormones that play a role in appetite involved in the brain-gut axis of eating behavior come from different sources. No studies have examined the effect of acute concurrent exercise on hunger and PYY. Our purpose was to investigate the effects of a bout concurrent exercise on hunger feelings and plasma PYY in in obese men. Materials and Methods: Twelve-four untrained obese male were volunteered to participate in this study. Participants after eating standard breakfast, performed 7 resistance exercises against resistance corresponding to 60% of 1RM bout then ran on the cycle ergometer for 30 minutes at 60% of maximum heart rate in a random cross-over fashion. Venous blood sample was obtained in pre exercise and 30min post exercise bout. Visual analogue scales (VAS) used to assess subjective hunger sensations. Data were analyzed by Student’s paired and unpaired t-tests. Statistical significance was set at P<0.05. Results: There was a significant increase in plasma PYY concentration at post exercise compared with pre exercise and control (p=0.038). Hunger scores were significantly decreased 30-min following the exercise period in experimental group (p=0.003). Conclusion: Our results showed that plasma PYY concentration increased and hunger depressed following a combined resistance and aerobic exercise at 60% of 1RM or HRmax in obese men. Therefore, increased plasma PYY concentration after a single concurrent exercise session in obese men may possibly contribute to hunger (appetite) suppression.
