Aim. The aim of this study was to determine the effect of incremental continuous running on changes in serum testosterone, and cortisol hormones responses.
Methods. With the approval of the Ethics Committee, 13 male athletic students were purposefully selected (weight 70.18 ± 4.4 kg, age 20.17 ±2.4 years, height 1.80 ± 0.33 m, VO2max 58.11 ± 3.21ml kg-1 min-1; means ± SD). The participants were trained according to an incremental continuous running program with a certain heart rate for two months (16 sessions). To determine the amount of serum cortisol and testosterone hormones, the participants’ blood samples were taken twice, once 24 hours before the first training session and once 24 hours after 16 sessions. Then, a 12-minute running-walking test was used to measure the maximal oxygen consumption (VO2max).
Results. There were no significant differences between the amounts of testosterone and cortisol hormones secreted in pre-test and post-test.
Conclusion. It seems the hormone response to exercise is dependent on several factors including the intensity, duration, and mode of exercise and the training status of the subject.
