The aim of the study is to investigate the physical activity level, aerobic capacity and dietary habits among a cohort of females with premenstrual syndrome

premenstrual syndrome can be defined as a recurrent disorder that occurs every month in the luteal phase of the menstrual cycle, and subside with the onset of menstruation. It is characterized by a complex set of symptoms, which include physical, psychological and behavioral changes with varying severity. This can interfere with the lives of females. Physical exercise improves PMS through rising endorphin levels, reducing adrenal cortisol symptoms, leading to lesser anxiety, depression and greater pain tolerance, as previous studies showed that it was effective in decreasing pain as well as mental and physical symptoms of PMS. Recently, lifestyle changes have gained more importance than pharmacotherapy. Lifestyle changes include many methods including diet regulation and exercise. 30 minutes of aerobic exercise is recommended for at least 3 days per week to contribute to the regulation of both body composition, mood and to improve physical symptoms. Evidence suggests that it can be helpful in reducing symptoms.
