Training protocol (aerobics and fitness training) consisted of four weeks, each week four sessions of 50 minutes with the intensity of 65-70% heart rate Reserve. Visual analog scale was used to measure the severity of pain and 1600m running test was used to measure the maximal consumed oxygen. Data was analyzed with SPSS software (version 18) and Wilcoxon test and Mann Whitney U test. PResults: The exercise caused increase in maximal consumed oxygen and significant reduction in the severity of dysmenorrhea pain and resting heart rate from pre-test to post-test in both groups (P<0.05), but there was no significant difference between the morning and evening groups in the mentioned variables (P>0.05). There was no significant difference between pre-test and post-test in blood pressure and body temperature in two morning and evening groups (P>0.05). Also, there was no significant difference between two groups in terms of blood pressure and body temperature (P>0.05).
