12-weeks resistance training is to investigate the effects on the hormonal and neurotransmitter activity, Identify the effective exercise of the Middle Ages and through it to become helpful in improving health and fitness. This study is nineteen subjects, members of S hotel fitness center, participated in having normal body composition with no medical problem. They were divided into two groups: control group (nine of them) and Weight Training Group (the other ten). The subjects were between the ages of 40 and 50, who exercised less than once a week within the last three months, and the WT was conducted regularly resistance training program of fitness center for twelve weeks. From each group, blood was collected to examine and compare changes in testosterone, growth hormone, cortisol, epinephrine, norepinephrine, serotonin and dopamine. Weight, muscle mass and body fat were measured to examine changes in body composition. Using SPSS Statistics 21.0 examined by using paired sample t-test, while a two-way ANOVA checked difference within groups. LSD was used for post verification. Weight did not show any significant difference in both groups for 12 weeks. Changes in amount of muscle mass appeared to be significant between 0 to 6 week, and between 0 to 12 week in WT group. Body mass change was significantly different between 0 to 6 week in WT group, whereas there was no significant difference in control group. Level of testosterone changed significantly between 0 to 6 week in WT group, Level of growth hormone increased significantly for 12 weeks in WT group, Level of cortisol showed significant difference between 0 to 12 weeks in WT group, but difference in control group was not significant. Level of cortisol showed significant difference between 0 to 12 weeks in WT group, but difference in control group was not significant. Changes in activity of neurotransmitter including epinephrine, norepinephrine, serotonin, dopamine were not revealed in both groups. In conclusion, 12-week resistance training seemed to have positive effect on changing body fat, and releasing testosterone and growth hormone, while it did not effect activity of neurotransmitter (epinephrine, norepinephrine, serotonin, dopamine). therefore, more studies are necessary which examine relation between resistance training and aerobic exercise.
