Women dancers were asked to state the degree of dysmenorrhea according to pain scale. The results of pain scale by dysmenorrhea were follows: 1) 60.7% of the participants were scaled at 4-5. 2) 21.9% of the participants were scaled at 6-7. 3) 12.9% of the participants were scaled at 2-3. 4) 2.7% of the participants were scaled at 8-10 5) 1.8% of the participants were scaled at 0-1. Statistical analyses revealed that there was a significant difference in the intensity of pain by dysmenorrhea- induced pain across dance type(x²=24.63, p<001), suggestion a trend in the negative effect of excessive training on dysmenorrhea. On the other hand, no significant differences in menstrual cycle, menstrual flow amount, premenstrual syndrome, and dysmenorrhea symptoms were found across the dance type.
