‘+’: perceived menstrual flow rated as light, medium, or heavy (score 1 to 3). Control and Dysmenorrhea groups were defined according to the definitions of inclusion criteria from the VAS scores of the Short Form McGill Pain Questionnaire in the current study. Superscripts numbers (1, 2, and 3) indicate significant differences (P < 0.05) between the groups. Dysmen and DysmenHIIT represent the dysmenorrhea groups not undergoing exercise and undergoing exercise treatments, respectively.
