Hormones affect almost all physiological aspects and actually act as a complementary part of the central nervous system. The aim of the present study was to determine the effect of eight weeks of home exercise on cortisol, androgen dehydroepiandrosterone and the ratio of androgen dehydroepiandrosterone to serum cortisol in female high school students. 16 female students of the second secondary level of Golbahar city were purposefully selected and randomly placed in two educational and control groups (8 people in each group). The exercise group participated in an 8-week exercise program at home including aerobic exercises 5 sessions per week and each session for 20, 25, 30, 35, 40, 45, 50, and 55 minutes for the first to eighth weeks. Before and after eight weeks, resting blood samples were taken from both groups, and the amounts of cortisol, dehydroepiandrosterone, and the ratio of dehydroepiandrosterone to cortisol were measured and calculated. The statistical method of analysis of variance between and within the subjects was used to compare the changes in the variables between the two groups. Cortisol in the training group compared to the control group means increased (P=0.026). Dehydroepiandrosterone and the ratio of dehydroepiandrosterone to cortisol decreased significantly in the training group compared to the control group (P=0.005 and P=0.006, respectively). Probably, eight weeks of aerobic training has led to the development of catabolic conditions in high school female students, which may lead to the prevention of overweight in them.
