About this study
Official title: Effects of Yoga on Menstrual Symptoms, Pain, Sleep Quality, and Aerobic Endurance in Young Women With Primary Dysmenorrhea: A Randomized Controlled Trial
The goal of this clinical trial was to assess whether a yoga-based exercise program could improve aerobic endurance, sleep quality, and reduce menstrual symptoms and pain in young women aged 18-25 with primary dysmenorrhea.
The main questions it aimed to answer were:
Read more
Did yoga reduce menstrual pain and symptom severity?
Did yoga improve sleep quality and aerobic endurance?
Researchers compared a yoga intervention group to a control group to determine whether the yoga program led to improvements in these outcomes.
Participants:
Were randomly assigned to either a yoga group or a control group
Completed assessments of menstrual pain (VAS), menstrual symptoms (Menstrual Symptom Scale), sleep quality (Sleep Diary), and aerobic endurance (Incremental Shuttle Walk Test and Endurance Shuttle Walk Test)
In the intervention group, attended 50-minute yoga sessions twice a week for three menstrual cycles
Participants in the control group were offered the same yoga program after the study period.
Read the detailed description
Primary dysmenorrhea, defined as painful menstruation without an identifiable pelvic pathology, is one of the most prevalent gynecological conditions among young women, affecting up to 90% of this population. It is typically characterized by cramping lower abdominal pain, often accompanied by back or thigh discomfort, and may be associated with systemic symptoms such as nausea, fatigue, and gastrointestinal disturbances. These symptoms can impair daily functioning, reduce sleep quality, and limit physical activity and endurance. While pharmacologic treatments remain first-line therapy, non-pharmacologic, low-risk, and accessible interventions such as yoga have gained attention for their potential holistic benefits.
This randomized controlled trial was designed to evaluate the effects of an 8-week structured yoga program on aerobic endurance, sleep quality, menstrual pain, and menstrual symptom severity in young women with primary dysmenorrhea.
A total of 32 female participants, aged 18-25 years, who had reported primary dysmenorrhea with menstrual pain intensity greater than 40 mm on the Visual Analog Scale (VAS) for at least the past 6 months, were recruited and randomly assigned to either a yoga intervention group (n = 16) or a control group (n = 16). Participants were recruited through convenience and snowball sampling methods via social media and community announcements. Exclusion criteria included regular physical exercise, irregular menstrual cycles, pregnancy, prior childbirth, pelvic surgery, or use of hormonal or psychiatric medications.
The yoga program was delivered twice weekly in 50-minute sessions for 8 weeks (across three menstrual cycles). It included:
Asanas (postures) targeting flexibility and pelvic mobility
Pranayama (breathing exercises) aimed at autonomic regulation
Relaxation and mindfulness components to reduce stress and improve sleep
All participants underwent assessments at three timepoints (baseline, after menstrual cycle 1, and after menstrual cycle 3), specifically during the first 3 days of their menstruation.
Outcome Measures:
Pain intensity: assessed via Visual Analog Scale (VAS)
Menstrual symptoms: evaluated using the Menstrual Symptom Questionnaire (MSQ)
Attitudes toward menstruation: measured through the Menstrual Attitude Questionnaire (MAQ)
Sleep quality: assessed with a Sleep Diary, capturing both quantitative sleep parameters and subjective quality
Aerobic endurance: measured using two field tests:
Incremental Shuttle Walk Test (ISWT) - to evaluate maximum aerobic capacity
Endurance Shuttle Walk Test (ESWT) - to assess submaximal endurance at 70-85% VO₂peak
Each test included pre- and post-assessment of vital signs (heart rate, oxygen saturation, blood pressure) and perceived exertion (Modified Borg Scale). Testing was stopped according to safety thresholds (e.g., failure to match the pace, HR >85% max, or participant-reported symptoms).
The primary hypothesis was that the yoga group would show statistically significant improvements in sleep quality and aerobic endurance, and reductions in menstrual pain and symptom severity, compared to the control group.
This study aimed to contribute to the growing body of evidence supporting yoga as a safe, accessible, and non-invasive strategy to manage primary dysmenorrhea and its associated physical and psychological burdens in young women. The findings may have implications for broader implementation in university and workplace settings to support menstrual and general well-being.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Yoga Exercise ProgramOther
Participants in the intervention group received a structured yoga-based exercise program consisting of 50-minute sessions, conducted twice per week over a period of approximately 10-12 weeks (three menstrual cycles). The program was based on Hatha Yoga principles
| Study group | Role | What they receive |
|---|---|---|
| Yoga Intervention | Experimental | Participants in this group received a structured yoga program consisting of 50-minute sessions, twice per week, over three menstrual cycles. Receives: Other: Yoga Exercise Program |
| Control Group | No intervention | Participants in this group received no intervention during the study period but were offered the yoga program after completion of the study. |
What is being measured
The primary outcome is the main question the study is designed to answer.
Sleep Quality
Change in sleep quality assessed using the Sleep Diary across three menstrual cycles. Includes measures such as sleep onset latency, total sleep time, number of awakenings, and subjective sleep quality.
Measure Type: Continuous (sleep parameters in minutes and Likert-scale scores) Sleep Onset Latency (in minutes) Total Sleep Time (in minutes) Number of Awakenings (count) Subjective Sleep Quality (Scale 1-5)
Measured: Since the menstrual cycle length varies between 28-35 days Baseline, at the end of Menstrual Cycle 2 (approximately Day 56-70), and at the end of Menstrual Cycle 3 (approximately Day 84-105)
Aerobic Endurance
Change in aerobic endurance assessed via Incremental Shuttle Walk Test (ISWT) Measure Type: Continuous (distance in meters)
Measured: Since the menstrual cycle length varies between 28-35 days Baseline and at the end of Menstrual Cycle 3 (approximately Day 84-105)
Aerobic Endurance
Change in aerobic endurance assessed by Endurance Shuttle Walk Test (ESWT). Time to exhaustion during the ESWT, used to assess submaximal aerobic endurance Measure Type: Continuous (minutes)
Measured: Since the menstrual cycle length varies between 28-35 days Baseline and at the end of Menstrual Cycle 3 (approximately Day 84-105)]
Secondary outcomes (2)
Menstrual Pain Intensity
. Pain severity will be assessed using a 100 mm Visual Analog Scale (VAS), where 0 mm indicates "no pain" and 100 mm indicates "worst imaginable pain." Measure Type: Continuous (VAS score in millimeters)Scores will be recorded during the first 3 days of menstruation across three menstrual cycles.
Measured: Since the menstrual cycle length varies between 28-35 days Baseline, at the end of Menstrual Cycle 2 (approximately Day 56-70), and at the end of Menstrual Cycle 3 (approximately Day 84-105)
Menstrual Symptom Severity
Menstrual symptoms will be assessed using the Menstrual Symptom Questionnaire (MSQ), a 24-item self-report scale evaluating the severity and frequency of physical and emotional symptoms related to menstruation. The total MSQ score is calculated by summing item responses. Higher scores indicate worse (more severe) menstrual symptoms Measure Type: Continuous (total MSQ score) / Score range: 0 to 96
Measured: Since the menstrual cycle length varies between 28-35 days Baseline and at the end of Menstrual Cycle 3 (approximately Day 84-105)

The goal of this clinical trial was to assess whether a yoga-based exercise program could improve aerobic endurance, sleep quality, and reduce menstrual symptoms and pain in young women aged 18-25 with primary dysmenorrhea.
The main questions it aimed to answer were:
Did yoga reduce menstrual pain and symptom severity?
Did yoga improve sleep quality and aerobic endurance?
Researchers compared a yoga intervention group to a control group to determine whether the yoga program led to improvements in these outcomes.
Participants:
Were randomly assigned to either a yoga group or a control group
Completed assessments of menstrual pain (VAS), menstrual symptoms (Menstrual Symptom Scale), sleep quality (Sleep Diary), and aerobic endurance (Incremental Shuttle Walk Test and Endurance Shuttle Walk Test)
In the intervention group, attended 50-minute yoga sessions twice a week for three menstrual cycles
