The purpose of this study was to investigate the effects of combined training and green tea supplementation on concentrations of testosterone and sex hormone-binding globulin plasma in overweight men. 24 sedentary overweight men (36.35±5.03 years) were randomly divided into three groups:1- supplement green tea+combined training, 2- placebo+combined training, 3-green tea supplement. The first and third groups were consumed one capsule (500mg) per day green tea supplements and the second group one capsule of starch supplements per day for 10 weeks. First and second groups began combined training (resistance training 60-75% one repetition maximum and 20 minutes of aerobic exercise intensity of 60-75% of maximum heart rate) for 10 weeks (three times a week and 2 hours a day). Blood samples were collected before and after supplementation and combined training to determine concentrations of testosterone and SH-BG plasma. Data was analyzed using ANOVA test (P≤0.05). Results Show that after 10 weeks of combined training were not significantly changes in the Concentrations of total testosterone, free testosterone and SH-BG plasma. Furthermore, no significant change in the Concentrations of total testosterone, free testosterone and SH-BG plasma, after taking green tea supplements was not found. Results of this study showed that 10 weeks combined training and green tea consumption didn’t effect on the Concentrations of total testosterone, free testosterone and SH-BG plasma. With regard to the efficacy of many herbal supplements may appear after prolonged use, it is recommended that next studies assess the effect of prolonged use of this plant
