The mean of dysmenorrhea duration of each cycle and days of bleeding were 2. 49 days and 6. 96 days، respectively. The mean of pain scores was similar in two groups before the intervention but it was significant after the intervention (p<0. 001). There was a significant difference in the exercise group in terms of pain severity before and after intervention (p<0. 001); while، there was no difference in the control group in this regard (p=0. 81).
