The Effect of Aerobic Exercise Training and Detraining on Some of the Menstrual Disorders in Non-athlete Students in Lorestan Universities

Early dysmenorrhea is a painful menstruation which happens without any pelvic pathological disorder and about 80% of women experience it. The purpose of this study was to investigate the effect of eight-week aerobic exercise trainings and detraining on the severity of dysmenorrhea and the amount of menstrual blood flow in non-athlete students. This study was semi-experimental in which sixty subjects were selected from students of Lorestan universities. After evaluating health status, early dysmenorrhea diagnosis and severe menstrual blood flow, the subjects were randomly divided into two equal control and exercise groups. The experimental group participated in an eight-week aerobic exercise training, three sessions per week. The severity of dysmenorrhea and the amount of menstrual blood flow were measured before and after exercise training and also after 48 days of detraining. Repeated measures of ANOVA and Cochran Q were used to analyze data. The aerobic exercise training significantly decreased early dysmenorrhea and menstrual blood flow in experimental group (p=0.001), but the positive effect of aerobic exercise training on the dysmenorrhea and menstrual blood flow was totally disappeared after 48 days of detraining (p=0.000). It seems that performing regular aerobic exercise training can be used as a preventing, treating or supplementary treating method in control of the early dysmenorrhea and the severe menstrual blood flow in non-athlete students.
