Influence of the Menstrual Cycle on the Maximal Strength of the External and Internal Rotators of the Shoulder in High-level Sports Women.

France16 participantsStarted 2025-09-01

Plain-language summary

The goal of this prospective interventional study is to measure the strength of the external and internal rotator muscles of both shoulders (dominant and non-dominant) of Montpellier Hérault Rugby players at different stages of their menstrual cycle. During the menstrual phase (beginning of the follicular phase from D0 to D5) and during the ovulatory/early luteal phase (approximately D13 to D18 of the menstrual cycle). The study is conducted on volunteers. The main question it aims to answer is : Is there an effect of the menstrual cycle on the maximum strength of the internal and external rotators of the shoulder in female athletes who play rugby?

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.
