Menstrual Cycle and Women's Performance
Czechia32 participantsStarted 2026-04-01
Plain-language summary
This study examines how different phases of the menstrual cycle are associated with selected performance and musculoskeletal parameters in physically active women aged 18-35 years.
Participants will track their menstrual cycle using a mobile app for approximately 2 months and attend 3 laboratory visits scheduled to specific cycle phases.
At each visit, participants will complete non-invasive assessments including lower-limb strength/performance testing, musculoskeletal measurements (muscle and tendon properties), body composition assessment, and symptom-related questionnaires.
The goal is to improve understanding of physiological variability across the menstrual cycle and support evidence-based planning of training, testing, and clinical practice in women.

Inclusion Criteria:
* Female, age 18-35 years
Premenopausal
Occasional to recreational level of physical activity
Willing and able to track menstrual cycle using a mobile application for approximately 2 months
Willing and able to attend 3 laboratory visits scheduled to predefined menstrual cycle phases
Able to provide written informed consent
Exclusion Criteria:
* Irregular menstrual cycle (outside protocol-defined regularity)
Current pregnancy
Use of hormonal medication for therapeutic purposes (per protocol)
Current acute illness at time of testing
Musculoskeletal injury of the lower limb limiting safe performance testing
Contraindication to body composition assessment methods used in the study (e.g., BIA/DXA, per site protocol)
Any other condition that, in the investigator's judgment, may interfere with safe participation or data quality
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
What they're measuring

Phase-specific change in lower-limb neuromuscular performance across the menstrual cycle
Timeframe: Assessed at 3 laboratory visits across approximately 2 months (cycle tracking period)
