ABSTRACT
The purpose of the present study was determining and comparison responses of cortisol and testosterone hormones and also testosterone to cortisol ratio serums in three aerobic activity sessions by three various sport devices including treadmill, ergometer and elliptical in active young men. Nine active young men of Tehran city with mean age of 24.11±3.88 years old, 178.77±6.47 cm height, 72.1±10.12 kg weight participated in three activity sessions consisting 25 min aerobic activity with intensity of 85% maximal heart beat rate by three devices (treadmill, ergometer and elliptical). Before and immediately after each activity session, blood samples were collected and for each sample, values of cortisol, testosterone and testosterone to cortisol ratio were gauged and calculated. In order to compare between three activity sessions, variance analysis test with repeated measurements and LSD post-hoc test were utilized and to investigate each activity session T paired test was implemented. There wasn't any significant difference between cortisol, testosterone and testosterone to cortisol ratio by three devices (treadmill, ergometer and elliptical). Treadmill didn't generated any significant difference in variants. Ergometer made a significant increase in testosterone serum (p<0.031), but it didn't make any significant variation in two other variants. Elliptical caused a significant decrease in cortisol (p<0.02), a significant increase in testosterone (p<0.002) and a significant increase in testosterone to cortisol ratio (p<0.01). Hormonal response following activity with elliptical was more anabolic than activities with treadmill and ergometer. So, in the possible manner it's recommended to use elliptical for aerobic activities. Of course, the differences between the three sessions weren't significant and this recommendation is understood from inner-session investigation. By the way, rather researches are still required to propose more suitable sport devices with more confide.
