Background: Physiological studies suggest that sleep deprivation may influence bodyweight through affecting appetite (decreasing leptin and increasing ghrelin). The aim of this study was to evaluate the effects of 12 weeks of aerobic training on obesity indices, serum levels of ghrelin and leptin, and sleep quality in overweight and obese men. Materials and Methods: In this quasi-experimental study, 22 overweight and obese men with low sleep quality were randomly assigned to aerobic training (n=12) and control (n=10) groups. Aerobic training was performed (50-60 min/day, 3 day/week) for 12 weeks. Serum ghrelin and leptin and obesity and sleep quality indices were measured before and after the intervention. Changes in dependent variables resulting from the training intervention were assessed by dependant t-test using SPSS software. Results: After aerobic training, weight (p<0.03), body mass index (p<0.04), visceral fat (p<0.04), total abdominal fat (p<0.03), and sleep quality (p<0.001) significantly improved. However, ghrelin and leptin serum levels did not change in response to aerobic training (p<0.05) during the same period. Conclusion: Short-term aerobic training improved obesity indices and sleep quality in obese/overweight men, yet this improvement was not accompanied by changes in ghrelin and leptin serum levels.
