The purpose of this study was to examine the Influence of a single bout of circuit weight training on cortisol in the morning and evening. 10 male bodybuilding athletes from Tehran were voluntary selected and all subjects performed a single bout of circuit weight training programming in the morning and evening. (N=10, weight = 85.7 kg, age = 30.80 years, length =178 cm, training time = 8 am. & 16 pm.). Data was classified and described using standard deviation and mean. Data analyzed using Kolmlgroph Smirnof test, independent t-tests and dependent ttest. The results showed there were significant differences between the amount of cortisol hormones secreted of morning and evening in pre-test and post-test, But there were higher cortislo levels in the before and after of morning exercise into the before and after of evening exercise. The findings of this research indicate that cortisol hormones are influenced by the time of training which is due to circadian rhythm and training program in the morning and evening.
