Efficacy of a High-Intensity Interval Training Program and Analysis of Menstrual Health Experience in Women With Primary Dysmenorrhea: A Mixed-Methods Randomized Controlled Trial.

What this Trial Is About

Researchers are evaluating whether a 12-week online supervised high-intensity interval training (HIIT) program can reduce menstrual pain and improve quality of life in women aged 18 to 40 with primary dysmenorrhea. The study also explores how this exercise affects women's personal experiences with their bodies and menstruation, aiming to provide new non-drug methods for managing menstrual pain through both a randomized controlled trial and qualitative analysis. Participants are divided into two groups: one group receives a 2-hour online menstrual health education workshop plus twice-weekly supervised online HIIT sessions for 12 weeks, while the control group receives only the educational workshop. All participants complete weekly digital diaries during the intervention. Clinical measures such as pain intensity, quality of life, sleep quality, mood, and work productivity are collected at baseline, immediately after the intervention, and at follow-up visits up to nine months. During the study, participants will be assessed using pain scales, questionnaires, and weekly diary entries to capture both physical symptoms and personal menstrual health experiences. Researchers will analyze changes in pain intensity and other health outcomes over time, integrating quantitative results with diary insights to understand biopsychosocial effects. The total participation includes the initial 12-week intervention and follow-up assessments through month nine, with safety and adherence monitored throughout.
