Premenstrual syndrome is manifested by recurrent emotional and depressive symptoms that may be associated with maladaptive coping with stress situations and the enhanced release of stress hormones, like cortisol hormone. Although previous studies revealed a flattened diurnal cortisol slope in women with PMS compared to healthy controls, there is no previous work on the effect of aerobic exercise on diurnal cortisol pattern in premenstrual syndrome. Therefore, this study will aim to investigate the effect of aerobic exercise participation on diurnal cortisol pattern in premenstrual syndrome.This trial will include two groups; group (A) will consist of 14 females who will receive relaxation training for 8 weeks, while group (B) will consist of 14 females who will receive the same relaxation training along with aerobic exercise for 8 weeks.
The aim of this study will be to investigate the effect of aerobic exercise on diurnal cortisol pattern in premenstrual syndrome.
